MULTIPLE ELECTRICAL CONNECTOR WITH LON UDINAL SPACED CONTACTS CARRIED BY INSULATI KEY Filed June 10, 1963 3 Sheets-Sheet 5 INVENTOR Robefl H, SremKamp RMQDQM ATTORNEYS United States Patent MULTIPLE ELECTRICAL CONNECTOR WITH LONGITUDINAL SPACED CONTACTS CAR- RIED BY INSULATING KEY Robert A. Steinkamp, Middletown, Conn, assignor to Ripley Company, Inc., Middletown, Conn. Filed June 10, 1963, Ser. No. 286,775 12 Claims. (Cl. 20051.07)

This invention relates to electrical connectors and more particularly relates to an arrangement for simultaneously acomplishing a multiplicity of electrical connections.

A device embodying the invention may be adapted for many applications. However, a connector embodying the invention is particularly adapted for use in making electrical connections between a plurality of electrical conductors which are energized in accordance with specific intelligence and a device adapted to read-out and record the encoded intelligence. In practice, the invention may be embodied in an electrical connecting apparatus comprising a first contact carrier having contacts thereon which are energized in accordance with recorded or metered intelligence and a second contact carrier having contacts thereon arranged to make electrical engagement with preselected contacts of the first contact carrier. The contacts of the second contact carrier may be connected to a device arranged to read-out and record the intelligence encoded on the contacts of the stationary contact carrier.

The contacts of the first contact carrier may be electrically connected to a utility meter such as disclosed in copending application Serial No. 276,839 fied April 30, 1963, of Robert A. Steinkamp and assigned to the same assignee as the present application. In such application the first contact carrier would preferably be fixedly mounted on the exterior of a dwelling receiving electrical service and the contacts thereof would be energizable in accordance with the reading of the electric service recording meter. The second contact carrier is then carried by a service man having a read-out and/or recording device to determine the reading of a meter as encoded on the contacts of the first contact carrier. The second contact carrier is arranged to have the contacts thereon placed in predetermined electrical engagements with the contacts of the stationary contact carrier.

With such an arrangement the utility service man may simply and easily take a meter reading and have it recorded on the spot without entering the serviced structure JI observing the dials on the meter.

As will be apparent the stationary contact carrier is subjected to atmospheric conditions and therefore must be resistant to weather and should simply and ruggedly be constructed. Additionally, and quite importantly, the stationary and portable contact carriers must be so arranged that only preselected electrical engagement is made by the contacts of each of the carriers, otherwise faulty and erroneous readings could result. Moreover, both the stationary and portable contact carriers must be ruggedly constructed to insure efiicient operation thereof while being subjected to making and breaking of electrical connections therebetween many times.

Accordingly, the present invention provides a new and improved multiple electrical contact arrangement adaptable for the purposes described which is of simple, yet rugged construction and which is provided with means to insure that electrical engagement is made only between preselected contacts of the contact carriers. The present invention allows the contacts of each carrier to be brought into engagement only when the carriers are in a predetermined physical relation and the contacts are properly aligned, for predetermined engagement.

3,222,471 Patented Dec. 7, 1965 "ice An object of this invention is to provide a new and improved apparatus for simultaneously making a plurality of electrical connections.

Another object of this invention is to provide a new and improved electrical connector comprising first and second contact carriers having contacts thereon Wherein electrical engagement may be made between predetermined contacts of contact carriers only when the carriers and the contacts thereon are in a predetermined physical relationship and the contacts of each carrier are in a predetermined aligned relationship.

Another object of this invention is to provide a new and improved apparatus for simultaneously making electrical connections between a plurality of electrical contacts wherein the contact carrying members must be initially joined in a predetermined physical relationship and means are provided for preventing the making of electrical contacts between the contacts of the carrier members unless such physical relationship is first accomplished.

A further object of this invention is to provide new and improved apparatus for facilitating the transfer of intelligence stored on a plurality of electrical contacts in an encoded form to a read-out or recording device.

A still further object of this invention is to provide a new and improved electrical connecting apparatus of the type described which is simple and rugged in structure and which will withstand repeated making and breaking of electrical engagement between pluralities of electrical contact elements.

A still further object of this invention is to provide new and improved electrical connecting apparatus for making connections to a plurality of circuits at one location and then break the connection and use a portion of the apparatus to make connections to similar circuits at other locations without placing undue stress and wear on the connecting apparatus.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combinations of elements, and arrangements of parts will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.

FIG. is a perspective view, in part, of a contact and contact mounting means utilized in the contact carriers of FIGS. 6 and 7.

A first preferred embodiment of the invention comprises first and second contact carrying members 10 and 11. Carrier member 10 will hereinafter be refrred to as a receptacle or stationary contact carrier and carrier member 11 will hereinafter be referred to as a plug or portable contact carrier. As Will hereinafter be more fully de- "scribed portable contact carrier 11 is in the shape of a probe arranged to be inserted into a passage defined in stationary contact carrier 10, positioned therein and then rotated a predetermined angle to effect electrical engagement between the contacts carried by each of the carrier members 10 and 11 in a predetermined relationship.

Stationary contact carrier 10 is generally comprised 'of two parts, a mounting portion 12 and a cover portion 13. The mounting and cover portions matingly fit together to provide a weather-tight seal therebetween, as shown in FIGS. 2 and 3. Contact separating fingers or ribs 14 extend from the side walls of portion 12 and contact separating fingers or ribs 15 extend from the side 'walls of portion 13.

As more clearly shown in FIGS. 2 and 3 the contact separating fingers 14 and 15 are so formed as to define a passage 16 therethrough arranged to receive portable contact carrier or the probe portion of the portable contact carrier therein. Portions 12 and 13 define an aperture 17 in carrier member 10 aligned with the defined passage 16 to allow admittance of the probe portion 19 of portable contact carrier 11 into the passageway. To assure that probe 19 is inserted into the defined passage in a predetermined angular position aperture 17 is fromed with keyways 20 and 21 arranged to matingly receive keys formed on probe 11 as will hereinafter be more fully described.

The contact separating fingers or ribs 14 and 15 on each of the portions 12 and 13 are so dimensioned and spaced that each rib 14 is laterally aligned with a rib 15 with respect to the length of passage 16 and define contact receiving pockets therebetween. Therefore, contact receiving pockets 22 between the fingers 14 and pockets 23 between fingers 15 are in lateral alignment. Each of the pockets 22 and 23 is adapted to receive therein an electrical contact member 24 (only one shown) and 24 respectively, having a portion thereof 25 or 25 adapted to be connected to an external circuit and another portion thereof 26 or 26 adapted to-be electrically engaged by a predetermined contact on portable carrier member 11. As more clearly shown in FIGS. 2 and 3 when portions 12 and 13 are joined the fingers or ribs 14 on cover portion 12 are aligned with a predetermined finger or rib 15 on cover portion 13 and therefore contact receiving pockets 22 and 23 are aligned laterally of the direction of passage 16.

Provided in stationary contact carrier member 10 is a probe positioning means illustrated as a hemispherical seat 28 ararnged to receive therein the hemispherical nose 29 of probe 19 and halt insertion of probe 19 into passage 16 after it has traveled therein a predetermined distance such that it aligns contacts on probe 19 with contacts 24 and 24 or more specifically portions 26 and 26 of contacts 24 and 24 laterally across passage 16.

Portable contact carrier 11 comprises a cylindrical probe portion 19 terminating in hemispherical nose 29. The other end of probe 19 is mounted to a handle 31 as by means of threads 32 or other suitable means. A multiconductor cable 33 extends through handle portion 31 and a sealing grommet 34 therein into probe member 19 where A the individual conductors of cable 33 are selectively connected to contacts.

Defined in probe member 19 longitudinally thereof are slots 36 and 37 which in the illustrated embodiment of the invention are angularly displaced 180 degrees. Carried in slots 36 and 37 are contact mounting members 38 and 39, respectively, which are of an elastomeric material such as rubber or the like. The contact mounting members, as more clearly shown in FIGS. 3 and 4, are formed with a groove 40 therein on either side thereof which receive the edges of probe 19 defining slots 36 and 37 and in this manner are secured to probe member 19.

Contact mounting members 38 and 39 'are provided with a plurality of contact receiving apertures 42 therethrough in linear predetermined spaced relation corresponding to the spacing between contacts 24 and contacts 24 along the length of passage 16. The apertures 42 have a flange-like portion 43 intermediate the ends thereof adapted to fit into the necked down portions 44 of contacts 45. In this manner contacts 45 are secured in mounting members 38 and 39 and through the mounting members carried on probe 19.

Each of the contacts 45 at one end thereof is adapted to have connected thereto one of the conductors of the multi-conductor cable 33. As illustrated the contacts 45 have a Well 46 adapted to have one of the conductors soldered or otherwise joined thereto. The engaging surface 47 of contacts 45 extend beyond the upper surface of the mounting members 38 and 39. ipeoz3ttociveadraz.7t

The contact mounting members 38 and 39 extend beyond the peripheral surface of probe member 19. The width of the contact mounting members 38 and 39 is selected such that mounting members 38 and 39 act as keys to allow insertion of probe member 19 into passage 16 through aperture 17 only when probe 19 is in a predetermined angular position With aperture 17 and therefore passage 16. Mounting member 38 is selected to be of a width which will be matingly received by keyway 20 and mounting member 39 is selected to be of a width matingly received by keyway 21. With this arrangement it will be evident that there is only one position in which probe 19 may be inserted through aperture 17, one of the mounting members being of a greater width than the other.

Additionally a key member 48 is provided to form the leading portion of the keys. As shown in FIG. 2, member 48 is of generally I-shape cross section having upper and lower flanges of the same width as mounting members 38 and 39, respectively. Member 48 is initially inserted in slots 36 and 37 and rotated therein to achieve the position shown in FIGS. 1 and 2. The ribs 14 and 15 are further formed to define a continuation of keyways 2t and 21 as most clearly seen in FIGS. 2 and 3. However, ribs 14 are cut away on one side of keyway 20 adjacent the upper portion thereof and ribs 15 are cut away on one side of keyway 21 adjacent the lower portion thereof in order that probe 19 may be rotated in a predetermined direction (clockwise as illustrated) when it has been fully inserted into passage 16.

When probe 19 has been properly inserted through aperture 17 and seated against seat 28 to properly align the two rows of contacts 42 with contacts 24 and 24 or more specifically portions 26 and 26 thereof, the portable contact carrier may be rotated ninety degrees clockwise to bring contacts 45 into electrical engagement with preselected contacts 24 and 24 It will be noted that when the probe member 19 is rotated ninety degrees the contacts mounted on contact mounting member 38 will make electrical engagement with contact members 24 in mounting portion 12 and the contacts 45 mounted in mounting member 39 will make electrical engagement with contacts 24 carried in cover portion 13. It will further be noted that the ribs or fingers 14 and 15 are formed with shoulders 49 and 50, respectively, to prevent greater than a predetermined angular rotation of probe member 19. It will further be noted that the keyways defined by the ribs or fingers 14 and 15 are cut away on opposite sides thereof and while allowing ninety. degrees rotation in a clockwise direction to effect electrical engagement between the contacts 45 and 24, 24 will prevent further than a ninety degree rotation of probe 19. The shoulders 49 and 50 act as a stop by engaging the contact mounting members 38 and 39.

The contact carrier portions 12 and 13 are provided with mating collar portions 51 which define an aperture with keyways similar to aperture 17 with keyways 20 and 21. The collars 51 are so positioned and dimensioned that the probe 19 must be inserted into passage 16 a distance such that the mounting members 38 and 39 clear collars 51 before the probe 19 can be rotated. With this arrangement, the hemispherical seat 28 and the collars 51 act to position the prob-e member 19 in passage 16 such that the contacts carried thereon are laterally aligned with predetermined contacts 24 and 24 before the probe 19 can be rotated. Therefore the contacts on probe 19 and the contacts 24 and 24 are laterally aligned, with respect to passage 16 prior to contacts 45 being rotated into electrical engagement with contacts 24.

In the illustrated embodiment of the invention, the contacts 24 are arranged to be connected to conductors which are in parallel spaced-apart relation in an insulating medium. As illustrated the conductors to be connected to the contacts 24 are in a cable of ribbon or tape form. An adaptor member 52, having flanges 53 received in slots provided therefor by mounting and cover portions 12 and '13, respectively, is mounted on stationary contact carrier member and has spaced contact separating ribs or fingers 54 and 55 on the sidewalls thereof on either side of a slot-like aperture 56. Ribs 54 and 55 are vertically aligned with ribs 14 and 15, respectively. The cable 57 is selected such that the spacing between the conductors 58 thereof is the same as the spacing between the pockets defined between the ribs 14, 54 and 15, 55. To effect a positive electrical connection between the conductors 58 and predetermined ones of contacts 24 the conductors 58 are laid bare at the end thereof inserted into slot 56. The cable 57 may be secured to an insulating spacing element 59 such as by eyeleting or riveting (not shown) the ends of the conductors 58 to spacer 59, When spacer 59 is wedged between ribs 54 and 55 the conductors 58 are positively held against the turned ends 25 of contacts 24.

The disclosed apparatus may be utilized so that two cables 57 may be brought into slot 56 on either side of spacer 59 and connection made to the contacts 24 in the same manner as described above.

Alternatively, selected ones of the contacts 24 and the conductors 58 connected thereto may be connected in a coding arrangement to contacts 24 in portion 13 as will hereinafter be described. While the invention is illustrated as being arranged to receive cables containing a plurality of conductors in flat or ribbon form it is to be understood that the contacts 24 or modifications thereof may be connected to more conventional type conductors such as round wire carried in round multiple conductor cable. For this reason the contacts 24 and 24 may be formed with an aperture 60 (FIG. 1) therein to facilitate connection of a wire thereto and the carrier member provided with an aperture to admit such conductors.

Where it is desired to connect selected ones of contacts 24 to selected ones of contacts 24 an encoder 62 (FIG. 5) may be utilized. Flat cables 63 and 64 having conductors 65 and 66, respectively, are crossed and selected ones of conductors 65 and 66 are eyeleted together or otherwise electrically connected. Portion A of cable 64 is then folded over one side of the contacting portions C of cables 63 and 64 and portionB of cable 63 is folded over the other side of contacting portions C of cables 63 and 64 to provide electrical insulation over the eyelets 66. Alternatively cable portions A and B could be eliminated and insulating sheets used. Portion D of cable 64 is then folded along a forty-five degree line 67 and portion D then folded over contacting portions C so that the bare ends of conductors 65 and 66 of each cable are in alignment. The bare ends of conductors 65 may then be placed on one side of spacer 59 in electrical engagement with conductors 58 and contacts 24 at portions 25 and the bare ends of conductors 66 placed on the other side of spacer 59 in electrical engagement with contacts 24 Portion C with overlapped portions A and B are then rolled up to fit into recess R in carrier member 10 above ribs 14 and 15.

In this manner selected ones of contacts 24 and the conductors 58 connected thereto are cross connected to selected ones of contacts 24 With this arrangement the contacts 24 dependent on the state of energization thereof may be encoded in a manner which identifies the contact carrier 10. Thus a single probe member 11 may be utilized in conjunction with a plurality of stationary members to effect connections to the contacts of the stationary carrier members to read-out intelligence encoded on one set of contacts 24 and an identifying code on another set of contacts 24 It will of course be understood that other techniques of effecting cross connections between contacts 24 and 24 may be utilized, such as conventional round conductors.

To further weathproof carrier member 10, doors 68 and 69 may be hinged in carrier member to cover aperture 17 and may further be provided with spring means (not shown) to bias doors 68 and 69 toward a closed position. To prevent doors 68 and 69 from blocking exit of probe 19 from passage 16 by engaging mounting members 38 and 39, lips 68a and 69a are provided on the doors so that the doors may ride over mounting members 38 and 39 as probe 19 is withdrawn from passage 16.

In operation, the probe 19 is inserted into passage 16 in the angular position determined by the keys and keyways until nose 29 is properly seated in seat 28 and mounting members 38 and 39 clear shoulders 51. At this point contacts 45 on mounting member are laterally aligned with contacts 24 and contacts 42 on mounting member 39 are laterally aligned with contacts 24 Probe 19 may now be rotated until shoulders 49 and 50 on ribs 14 and 15 are engaged by mounting members 38 and 39, all respectively. At this time the contacts 45 make electrical engagement with contacts 24 and 24 The elastic material forming the contact mounting members and the resiliency of contacts 24 and 24 due to the shape and mounting thereof minimize loading of the contacts when they are brought into electrical engagement. When electrical connections between the contacts of the carrier members have been made and the desired information derived, probe 19 is rotated counter-clockwise until the keyways defined by ribs 14 and 15 prevent further rotation, probe 19 is withdrawn from passage 16 and carrier member 10, and thereafter may be utilized to make electrical connections with other stationary contact carriers.

For economy in manufacture, it is preferred that mounting portion 12 and cover portion 13 be of molded insulating material as well as adaptor 52. Mounting portion 12 may be formed with a tapered rear surface to angle passage 16 away from a wall upon which carrier member 10 is mounted and thereby facilitate insertion of probe 19 into passage 16. Probe 19 is preferably formed of aluminum and contacts 24, 24 and 45 of any suitable electrically conductive material having a high degree of corrosion resistance. In assembly of carrier member 10 contacts 24 are placed in pockets 22 and the pockets defined between ribs 54. Mounting portion 12 may then be secured to a mounting surface by bolts or the like (not shown). Spacer 59 is then properly positioned to connect conductors 58 with contacts 24 and one set of encoder conductors, if an encoder is used. Cover portion 13 together with the other half of adapter 52 with contacts 24 therein is then matingly joined to mounting portion 12, with the second set of encoder conductors engaging contacts 24 and cover portion 13 is secured to mounting portion 10 by bolts or the like.

A second embodiment of the invention is illustrated in FIGS. 6-10. This embodiment comprises a stationary contact carrier member 70 (FIG. 7) and a portable contact carrier member 71 (FIG. 6). The portable contact carrier member comprises a probe portion 72 of generally cylindrical form having a hemispherical nose 73 and a handle 74. The probe 72 as more clearly seen in FIG. 9 comprises two members 75 and 76 made of rigid insulating material and having an L-shaped key 77 along the length thereof. Probe member 72 is hollow to allow the conductors of a multiconductor cable 78 to pass therethrough and be connected to preselected contacts 79. The contacts 79 are aligned along the length of proble 72 on a mounting member or jig 80 which is carried by the members 75 and 76 forming the probe 72 parallel to a longitudinal axis of the probe. Key 77 is parallel to but offset from a longitudinal axis of the probe. Key 77 serves two functions, to align the probe with a receptacle therefor as hereinafter described and to shield the exposed portion of contacts 79. The contacts 79 as more clearly shown in FIG. are contoured so that they snap into place in pockets 81 in mounting jig 80. Contacts 79 are provided with an aperture 82 to receive a conductor 83 therein and allow soldering of the conductor to the contact. Contacts 79 are formed of a resilient electrically conductive material which is non-corrosive.

The stationary contact carrier member or receptacle 70 is composed of two pieces made of rigid insulating material so designed that when assembled a contact mounting jig 84 identical to jig 80 is held in place parallel to the longitudinal axis thereof. The members 82 and 83 forming the receptacle define a conductor conduit 86 therein to allow passage of the conductors 87 of a multiconductor cable 88 therethrough and connection of the conductors 87 to contacts 89 in mounting jig 84. Contacts 89 are similar to the contacts 79.

Receptacle 70 further defines therein a passage 90 arranged to admit probe 72 therein.

The receptacle is provided with a locking or mounting ring 91 having an aperture 92 with keyway 93 therethrough so that probe member 72 may be inserted into passage 90 in receptacle 70. As will be seen from the drawings, when probe 72 is inserted into passage 90, contacts 79 will be angularly offset from contacts 89 and electrical engagement therebetween cannot be effected un til probe member 72 is rotated while in passage 90. Keyway 93 is cut away on one side thereof within carrier member 70 to allow rotation of probe 72 therein when key 77 has cleared ring 91. Means are provided to insure proper positioning of probe 72 in passage 90 prior to making electrical contacts between the contacts carried by the respective members. The contact carrier members are so formed and dimensioned that when hemispherical nose 73 seats in a hemispherical seat 94 at the end of passage 90 the trailing edge 95 of key 77 clears mounting ring 91 and the contacts 79 on mounting jig 80 are laterally aligned with preselected contacts 89 on mounting jib 84. Thereafter to effect electrical engagements between contacts 79 and contacts 89, probe member 72 through handle 74 is rotated clockwise at which time the free ends 96 of contacts 89 and'79 which are of resilient material make a wiping engagement. Key 77 abutting mounting jig 84 and contacts 89 limits rotation of probe 72 in passage 90 as it is rotated in lateral extension 97 of key way 93 in passage 90. Thereafter, when it is desired to break the electrical connection between contacts 79 and 89, probe member 72 through handle 74 is rotated counter-clockwise until key 77 is aligned with keyway 93 and probe 72 is withdrawn from passage 90. The apparatus of FIGS. 6-10 provides means for positively making a plurality of electrical connections between predetermined contacts in the same manner as the apparatus of FIGS. 1-4.

It may thus be seen that the objects set forth above as well as those made apparent from the preceding description are efficiently attained.
