C. E.'QUINN Septn 6, 1949.

CONNECTOR Filed April l2, 1946 3nve`ntor CZaz Quinn Patented Sept. 6, 1949 :Asopos y coNNEcTon Clark E. Quinn, Highland Park, Mich., assilnor to General Motors Corporation, Detroit, Mich., a corporation of Delawaresppuesunn Api-u 12, laisserai No. $61.505 Y comme (c1. 11a-a' 2s) The present invention relates to electrical connectors and more specliically to connectors for extremely low voltage circuits, for example, thermopile circuits. 'I'he requirements for such a connector are extremely rigid since the introduction or losses of voltages of extremely small magnitude will cause a very high percentage of error. Such connections must contain a minimum of junctions to keep the contact losses as low as possible. The contact resistance between the materials used must be maintained at a minimum. The connections between these contacts should not be affected by vibration or tension on the cables. The above requirements must be met in order that the losses within the connection will be maintained as low as possible. In order to minimize the introduction of spurious voltages to the circuit the connector must be shielded thermally, electrostatically and magnetically. The connector and all parts carrying current must be of material which matches the thermal characteristics oi the associated conductors in order not to introduce thermal po tentials. The prior art shows various means of meeting one or two of the above requirements but no connection was available prior to the present invention meeting all of these require.- ments.

It is the object of the present invention to produce a connector in which the losses and introduction of extraneous voltages is minimized.

It is a. further object of this invention to make a connector which is thermally electrostatically and magnetically shielded.

It is also an object of this invention to produce a connector that is cheap to produce, efficient in operation and rugged in construction and fool-prooi in use.

It is a still further object of this invention to produce a connector having concentric axially biased contact elements.

Further objects of this invention will be apparent in the speciiication, illustrated in the drawings and specically pointed out in the claims.

Referring to the iigm-es:

Figure 1 is a sectional view of the conductor as it is assembled with a parallel line cable.

. I 2 I l Referring more specifically to Figure 1, the I conductors from the thermopile or otherspurce of voltage are shown as a cable consisting of wires 2 and 4 with rubber insulation l. This 5 cable has an armor lll soldered to a metallic spring 8 for securing said cable to the main casing of the plug l2. The set screw I4 .pre-l vents the transmission of any tension from the cable to the connectors. This plug carries therein an insulator oi phenolicl material li secured by set screw I6.

Outer contact element lI8 is secured to the insulator l5 by a press iit therein and is electrically connected to the wire 2. Insulator 2l is secured inside contact I8 by a press lit therein.

Inner contact 22 is secured by a press ilt in insulator and is electrically connected to wire 4. Another subassembly is contained in a shell 24 which is adapted to be screwed into an in- 20 strument cabinet or panel by means of threads 32 and is adapted to be secured to the plug l2 by means o! threads 30 in cap 26. said cap being secured to the plug I2 by snap :ring 28. The shell 24 carries therein, secured by set screw 42, an insulating member 34 which has openings therein for securing outer contact 3i and inner contact 44. Outer contact 36 is slidably secured to the insulator and limited in travel by ears 38 on the contact element. A compression .30 spring 40 biasesthis element into contact with the element I8 when the connector is in the assembled position. These ears also prevent the accidental disassembly of contact 36 when the plug is disconnected from the shell.

The inner contact 44 is slidably secured in the insulator 3 4 by means of pin 50. This pin peiforms the same function as the so-called ears 3l on the contact 36. This inner contact 44 is biased in an axial direction against the contact 22 by 40 means of compression spring 48. An insulator 48 is secured between the spring 4i and the contact 44. This insulator 48 also acts as a support to prevent canting of contact 44 with a resulting short circuit between it and contact 36.

45 Referring to Figure 2, the manner in which the ears 38 and the pin 50 restrain their respectivo contacts from excessive movement is shown.

From the above description it is apparent that a connector is produced having butt contacts of so uniform pressure which are not aiiected by tension on the cable and only slightly anected by vibration. It is also apparent that these contacts. being concentric, are free from such linkage of magnetic ux as would introduce currents therese in. I'he insulating materiel and the plugand 3 shell arrangement thermally and electrostatically shield the elements therein.

Referring to Figure 4, the shorting cap I2 has screw threads N therein for engagement with threads on the shell 24 to attach this cap to the shell. An insulator'll is retained in the cap by snap ring B6. This insulator may be of resilient insulating material, for example, rubber, or of comparatively non-resilient material, without departing from the scope of this invention. Secured to insulator 58 is a shortlng cap 60 made from material of high electrical conductivity, preferably but not necessarily the same material as contacts 38 and M.

It is to be understood also that although the invention has been described with speciilc reference to a particular embodiment thereof, it is not to be so limited, since changes and alterations therein may be made which are within the full intended scope of this invention as defined by the appended claims.

I claim:

l. A connector assembly adapted to mate with a second connector assembly to form a readily separable electrical connector, the first assembly including; an insulator, two concentric contact members slidable axially in said insulator, each of said contact members having an outwardly facing contact surface normal to the common axis of the contact members, means axially biasing each contact and urging its contacting surface in an outward axial direction with respect to said insulator, each contact member having a projection thereon engaging said insulator to hold it in assembly therewith.

2. A readily separable electrical connector having a ilrst connector assembly as claimed in claim 1 and a matingassembly including; concentric electrical contact members connected to ilexible electrical conductors and separated from each other by an insulating means.
