The terminals and insula tor housing are of a construction and arrangement such that the terminals serve the dual function of electrically connecting a wire conductor to the circuit board as well as to biasingly retain the circuit board in place within the housing.

5 Claims, 13 Drawing Figures PATENTEB FEB 4W5 SHEEI 10F 3 g 1 PRINTED CIRCUIT CONNECTOR TERMINAL The present invention provides an electrical connector means, and in particular, an electrical connector means comprising, in combination, a printed circuit board having a plurality of conductor strips thereon and a row of through openings spaced inwardly from an adjacent side edge of the printed circuit board, a plurality of terminals which are adapted to be simultaneously connected to the circuit board, a wire conductor connected to each terminal, and a plastic insulator housing for housing the printed circuit board, terminals and conductors.

I-leretofore, various terminals for engaging contact areas on one or both sides adjacent an edge of a printed circuit board have been provided to achieve an electrical connection between printed circuits on the circuit board and an electrical component. Housings have also been provided for retaining of the printed circuit boards and terminals.

The present invention provides a novel electrical connector means of the above noted type, but in which the printed circuit board has a row of openings spaced inwardly from its side edge and located adjacent contact areas of printed circuits and in which the various individual terminals are integrally connected via webs to a carrier strip and crimped onto wire conductors. The terminals are adapted to be simultaneously connected to the printed circuit board and thereafter the carrier strip is severed from the terminals. The present invention also includes a housing means for housing the circuit board and terminals. The terminals are of a novel construction such that they both provide an electrical connection to the printed circuit board and cooperate with the housing means to biasingly retain the printed circuit board within the housing.

Accordingly, an important object of the present invention is to provide a new and improved electrical connector means comprising a printed circuit board having a row of openings spaced inwardly from its adjacent side edge and located adjacent contact areas of printed circuits thereon and a plurality of electrical terminals integrally connected via webs to a carrier strip and which include spaced fingers for receiving the printed circuit board, and wherein the terminals are simulta'neously connected to the printed circuit board by inserting one of the fingers through he adjacent openings in the circuit board, simultaneously moving the terminals relative to the circuit board so that the latter adjacent the openings is received between the fingers of each terminal and thereafter severing the carrier I strip from the individual terminals.

A further object of the present invention is to provide a new and improved electrical connector means, as defined in the preceding object, and in which the terminals each comprise a pair of first laterally spaced fingers for engaging one side of the printed circuit board and a second finger having a first section extending transversely of the first finger, an intermediate section for engaging the opposite side of the printed circuit board and a third section extending transversely of the second section, and in which the printed circuit board is thicker than the spacing between the first and second fingers whereby the printed circuit board is biasingly engaged by the flexible fingers when received therebetween.

Yet another object of the present invention is to provide a new and improved electrical connector means, as defined in the next preceding object, and which further includes a housing means of a generally rectangular shape for receiving the printed circuit board, and in which the housing means includes a plurality of laterally spaced inwardly extending ribs on two opposite sides of the housing and wherein the resilient fingers are received between the adjacent ribs when the circuit board is inserted therein and the second finger deflected toward the circuit board by the housing means so that the printed circuit board is biasingly retained within the housing against the ribs on one side thereof.

A still further object is to provide a new and improved electrical connector means, as defined in the next preceding object, and wherein the first fingers of the terminals are substantially planar, engage the circuit board along their side edges and are deflected toward each other by the ribs on one side of the housing means when inserted between the ribs to aid in locating and retaining the circuit board within the housing means.

The present invention further resides in various novel constructions and arrangement of parts, and further objects, novel characteristics and advantages of the present invention will be apparent to those skilled in the art to which it relates and from the following detailed description of the illustrated embodiments thereof made with reference to the accompanying drawings forming a part of this specification and in which similar reference numerals or characters are employed to designate corresponding parts throughout the several views, and in which:

FIG. 13 is a fragmentary top plan view of the electrical connector means shown in FIG. 12.

The present invention provides a novel electrical connector means. Referring to FIGS. 1-9, the electrical connector means comprises, in general, a printed circuit board 10 having a plurality of printed conductor strips or circuits l2 thereon and a row of through rectangularly shaped openings 14 spaced inwardly from an adjacentend or side edge a of the circuit board, a plurality of electrical terminals which are received within the openings 14 and connected to the circuit board 10 adjacent the sides defining the openings 14, a plurality of wire conductors 24 which are crimped to the terminals 20 and a housing means 30 for receiving and housing the printed circuit board and terminals 20. The terminals 20, as will be hereinafter more fully described, function to provide both an electrical engagement between the wire conductors 24 and contact areas 12a of the printed circuits and to biasingly hold the printed circuit board in place within the housing 30.

The printed circuit board 10 made from any suitable electrically insulating material comprises a flat planar member. The conductor strips 12 are made from metal and are preferably bonded to the planar insulating member. The openings 14 are in a row and are spaced inwardly from the side surface 10a of the printed circuit board.

The terminals 20 are made from suitableor conventional, thin, flat metal stock which is cut and thereafter bent to the configuration shown in FIG. 3. The terminals 20 include a rearward portion 40 and a forward portion 42. The rearward portion 40 includes spaced pairs of crimping flanges 44 and 46, which are adapted to be crimped onto the bare end 24a and insulator por' tion 24b of the wire conductor 24, as shown in FIG. 1. The wire conductor 24, upon being crimped to the crimping flanges 44, 46 lies over the forward portion 42 of the terminal 20. The rearward portion 40 is also bent to provide an upwardly extending beveled surface 48 intermediate its ends, and for reasons which will be more fully described hereinafter.

The forward portion42 includes a pair of laterally spaced upper fingers 50 which are integrally connected by a transverse bridge section 52 adjacent their ends closest to the rearward portion 40. The fingers 50 each comprise a first or inner section 54 which is adapted to engage one side of the printed circuit boardv and a second or outer section 56 extending transversely of the first section 54 and which terminate in a curved free or outer end 58. The second section 56 forms an obtuse included angle with the first section 54, preferably of approximately l 1 0.

The forward portion also includes a lower finger 60 which is integral with the bridge portion 52 intermediate the upper fingers 50. The lower fingers 60 include a first or inner section 62 extending transversely or normal to the first section 54 of the upper fingers 50, an intermediate or second section 64 which is adapted to engage the opposite side of the printed circuit board when the latter is received between the fingers 50 and 60 and an outer or third section 66 which extends transversely outwardly of the intermediate section 64 and which terminates in a curved free or outer end 68. The outer section 66 forms an obtuse included angle with respect to the intermediate sections 64, preferably of approximately 110.

The terminals 20 are preferably made from a metallic material which is flexible and substantially resilient. That is, a material which can be deformed to a new shape, but yet be resilient enough to provide good spring back characteristics. The transverse distance between the sections 54 and 60 of the fingers 50 and 60 when the terminal 20 is in its free state is less than the given thickness of the printed circuit board 10. The intermediate section of the finger 60, when in its free state, forms an acute included angle with respect to the first section 54 of the fingers 50, but is adapted to be disposed parallel with respect to the first sections 54 when the printed circuit board is received between the fingers 50 and 60. The flexibility of the finger 60 is enhanced by providing the fingers 60 with a reversely bent bight portion 70 at the juncture of the sections 62 and 64. The radius of the bight portion 70 is such that the sections 64 and 66 of the finger 60 can be flexed and still have excellent spring back toward its free state position.

As alluded to hereinbefore, the terminals 20 are stamped and bent to the configuration shown in HO. 3 by a suitable punch and die apparatus. The terminals 20 are initially integrally connected via webs 71 to a carrier strip 72, shown in phantom in FIG. 1. While the terminals remain connected to the carrier strip 72, the individual insulated wire conductors are crimped to the terminals 20 via the crimping flanges 44 and 46.

The terminals 20 are adapted to be simultaneously connected to the printed circuit board 10. The terminals 20 are connected by inserting the fingers 60 through the openings 14 in the printed circuit board 10 and thereafter pulling the terminals 20 via the wire conductors 24 to the right, as viewed in FIG. 2, so that the edges of the circuit board 10 adjacent the openings 14 are received between the fingers 50 and 60. The circuit board 10 adjacent its lower side will have a contact area 12a which is engaged by the finger 60 to provide an electrical contact therebetween. During connection of the terminals 20 to the circuit board 10, the fingers 60 will be deflected downwardly slightly, since they are more flexible than the fingers 50 due to the provision of the bight portions 70. After the terminals 20 are connected to the printed circuit board 10, the carrier strip 72 is severed by a suitable punch and die so as to leave the individual terminals 20 connected to the board 10, but separated from one another.

The printed circuit board 10 and terminals 20 when connected thereto are adapted to be connected to the housing 30. The housing 30 is made from a suitable insulating material, such as plastic, and is of a generally rectangular, hollow shape having upper, lower and side walls 81-84, respectively. The housing also has a closed end wall 85 at one end and an open end 86 at its opposite end. Extending inwardly from the upper wall 81 are a plurality of integral, laterally spaced, thin longitudinally extending ribs 90. Extending inwardly from the bottom wall 82 are a plurality of integral, laterally spaced longitudinally extending ribs 91. The ribs 90 and 91 are aligned with each other, but spaced apart to provide a transversely extending space 92 into which the circuit board 10 can be inserted. The ribs 91, as best shown in FIG. 9, have a bevelled entry end 94 to guide the circuit board 10 between the ribs 90 and 91 when inserted therein, a first intermediate portion 95 of a given height, a second bevelled cam surface portion 96 intermediate its ends, and an end portion 97 of a greater height than the portion 95. The ribs 91 also have an increasing thickness proceding from the open end 86 of the housing toward the closed end 85 of the housing.

The circuit board 10 is adapted to be inserted within the housing 30, terminal end first. As it is inserted within the housing 30, the circuit board 10 will be received between the ribs'90 and 91 and with the terminals 20 being received between adjacent ones of the ribs 90 and 91. It should be noted at this point that the dimension between the outer free ends 58, 68 of the upper fingers 50 and the lower fingers 60 when the terminal is being connected to the circuit board is greater than the transverse distance between the upper and lower walls 81 and 82. Thus, as the terminals are received between the ribs 90 and 91, the outermost leg sections 56 and 66 will be deflected toward each other. The upper sections 56 of the terminals 20'will flex a greater extent than the sections 66,'since they are more flexible due to their greater length. The circuit board 10 is thus biased upwardly against the ribs 90 by the sections 66 of the terminals and biasingly held in place. When the board 10 is fully inserted, its forward" end will be received between the sections 97 of the ribs 91 and the ribs 90. The reason for the different height portions 95, 97 is that the circuit board has different portions of different thicknesses. The beveled surface 96 will cam the board 10 onto the rib portion 97 should the board 10 not be engaged with the ribs 90 as it is being inserted into the housing 30.

It should be apparent that the terminals 20 provide the dual function of providing an electrical connection between the contact area of the printed circuit board and the wire conductor as well as to biasingly hold the circuit board 10 in place within the housing 30. The provision of the tapered ribs 91, causes the lower fingers 60 to be guided so that the circuit board 10 is located within a predetermined location within the housing 30.

The housing 30 is adapted to be connected to a mating connector housing (not shown) containing terminals which engage the opposite end of the printed circuit board. To this end, the housing 30 has an integral hook 100 formed integral with its side 83 which is adapted to be received wihtin a suitable opening and mate with a catch in the mating connector housing and a deflectable forwardly extending finger 104 having an enlarged end 105 which is adapted to be snapped fittingly received within a catch member formed integral with the mating connector housing.

The various wire conductors, which extend between the adjacent ribs 90, are adapted to a bent 90 and be contained within anaxially slit corrugated conduit 106 connected to the housing 30 and shown in phantom in FIG. 7. To this end, the housing includes a stationary semi-circular portion 107 extending transversely of its right sidewall 84. The semi-circular portion has a semicircular radially inwardly extending rib 108 and a nib or catch 109 formed integral therewith at its upper end. The deflectable finger 104 is also formed integral with the upper end of the portion 107. The portion 107 has formed integral therewith adjacent its lower end, as

viewed in FIG. 8, a second semi-circular portion 110 which is integrally hinged to the semi-circular portion 107 via a flexible hinge 112. The semi-circular portion 110 has a semi-circular radially inwardly extending rib 115. The semi-circular portion 110, adjacent its free end, carries a deflectable latch 116 having an opening '117 therein.

The corrugated tube 196 is adapted to be connected to the housing by positioning the end of the tube within the semi-circular portion 107 and with the rib 108 being received between adjacent ones of the corrugations and then moving the semi-circular portion 110 upwardly about its hinge 112 towards the portion 106 and with its rib 115 being received between adjacent ones of the corrugations until the latch 116 engages the catch 109 and is deflected thereover to receive catch 109 within the opening 117. This secures the corrugated tube 106 to the housing 30.

FIGS. 10-13 show a second and preferred embodiment of an electrical connector means of the present invention. The electrical connector means of FIGS. 10-13 is identical to the electrical connector means of FIGS. l-9, except that different terminals are employed. The parts of the electrical connector means of FIGS. 10-13, which are identical to the parts of the electrical connector means of FIGS; l-9, have been given the same reference numerals.

The terminals 130 are of an identical construction to the terminals 20 except that different first fingers 132 are provided. The portions of the terminals 130 which are identical to the portions of the terminals 20 have been given the same reference numerals, but with a prime affixed thereto.

The fingers 132 of the terminals 130 are of substantially planar and rectangular shape. The fingers 132 adjacent their ends closest to the rearward portion 40' are bent upwardly so as to be disposed perpendicularly to the bridge section 52'. The fingers 132 along their lower side edges 135 are adapted to engage the top side of the printed circuit board 10. The terminal 130, when in its free state, has a transverse dimension between the lower side edges 135 of the fingers 132 and the intermediate section 64' of the finger 60 which is less than the thickness of the circuitboard 10.

The terminals 130 are interconnected via webs to a carrier strip 142 and are adapted to be simultaneously connected to the circuit board 10 in the same manner as previously described in connection with the terminals 20 except that the side edges 135 of the fingers 132 engage the top side of the circuit board 10. The finger 60 deflects about its bight portion 70 when being connected to the circuit board 10 and biases the circuit board against the side edges 135 of the upper fingers 132. After the terminals are simultaneously connected to the circuit board 10, the webs l40 are severed to individually separate the terminals 130.

The fingers 132 have curved outer ends so are laterally bent at the bridge section 52so as to diverge away from each other proceeding from the bridge section 52 toward their outer ends 150. The transverse distance between the outermost sides of the curved ends 150 is slightly greater than the transverse distance between adjacent ribs 90 of the housing means 30.

The circuit board 10 containing the terminals 130 is connected to the housing means 30 in the same manner as the circuit board 10 containing the terminals 20 except that the fingers 132 are deflected toward each other by the adjacent facing sides of the ribs 90. Entry of the fingers 132 between the ribs 90 is facilitated by the curved ends 150. The finger 60 serves to bias the circuit board 10 against the underside of the ribs 90 and the fingers 132 serve to locate and aid in retaining the circuit board 10 in place. The fingers 132, 60 also serve to prevent rattling of the circuit board 10 within the housing means 30 when connected thereto.

Although the illustrated embodiments hereof have been described in great detail, it should be apparent that certain modifications, changes, and adaptations may be made in the illustrated embodiments, and that it is intended to cover all such modifications, changes and adaptations which come within the spirit of the present invention.
