1 ZERO-INSERTION FORCE CONNECTOR BACKGROUND or THE INVENTION Zero-insertion force connectors to date have been relatively expensive to manufacture due to the relatively high number of parts involved and, in some instances, close tolerance parts requiring expensive manufacturing processes such as machining. Other such connectors have intricate actuating mechanisms and generally two actuating members, one for each side of the circuit board or substrate.
It is therefore an objective of the present invention to provide a relatively inexpensive zero-insertion force connector having a relatively few number of parts.
It is a further object of the invention to provide a connector having a single actuator for actuating two opposing rows of contacts.
It is still another object of the invention to provide a connector of small compact size and configuration allowing for high density package of electronic components.
SUMMARY OF THE INVENTION The above objects are carried out by providing a connector of generally rectangular box-like configuration having a circuit board or substrate receiving cavity in the top wall. Located to either side of the plane of insertion of the circuit board is a row of electrically conductive leaf spring contacts with the free ends in engagement with the upper end of a respective rocker member located on each side of the plane of insertion. The lower end of each rocker member is in engagement with an elongated cam member whose axis is in the plane of insertion. Rotation of the cam member forces the leaf s ring contact portions against circuitry located on the two faces of the inserted board or substrate.
Other objects and attainments of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings in which there is shown and described an illustrative embodiment of the invention; it is to be understood, however, that this embodiment is not intended to be exhaustive nor limiting of the invention but is given for purposes of illustration and principles thereof and the manner of applying it in practical use so that they may modify in various forms, each as may be best suited to the conditions of a particular use.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective view of the invention prior to insertion of a circuit board;
FIG. 2 is an exploded perspective view of the invention;
' FIG. 3 is a section view along line A-A of FIG. 1 showing DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings there is shown the connector of the preferred embodiment. The connector 10 comprises a generally rectangular box-like housing 12, preferably of metal construction, having top 14, side 16, and end walls 18. Bottom wall 20 (see FIGS. 3 5) is formed primarily by dielectric carrier members 22, 24, each carrying a row of 25 electrically conductive contact members 26. The number of contacts 26 may be varied to suit a particular application. The carrier members 22, 24 are identical and oppositely disposed with each having mating tongues 28 and grooves 30. The tongues 28 and grooves 30 are intermated and the two carrier members 22, 24 with respective contacts 26 are cemented or otherwise bonded in position in FIGS. 1 and 3 5. With sidewalls l6 and end walls 18 the upper surfaces 32 of carrier members 22 24 forrnan elongated cavity C generally symmetrical about a plane of insertion 34. Each row of contacts 26 is spaced equidistant from plane 34.
Contact members 26 are all identical and each include a lead end 36 suitable for wire wrap, solder, mother circuit board, or other appropriate electrical connection with external circuitry. Contact members 26 are slightly ofiset as at 38 to facilitate or aid in retention within molded carrier members 22, 24. The contact members 26 are bent inwardly at '40 toward plane 34 and then reverse curved outwardly near the end portions to form a leaf spring contact portion 42 for electrical engagement with circuitry 44 of a circuit'board'46.
Located in cavity C adjacent each sidewall 16 is an elongated comb-like rocker member 48. Each rocker member 48 has an elongated generally cylindrical surface 50 located on a first side 51 thereof and is in pivotal engagement by means of cylindrical extensions 52 with respective upstanding supports 53. The opposite or second side 54' of rocker member48 on the upper end thereof has an elongated groove or notch 56 within which the free-ends 58 of leaf spring contacts portions 42 abut. The lower end of comb-like rocker member 48 is comprised of a plurality of tooth-like members 60 of a number one less than the number of contact members 26 with each tooth between and separating adjacent contact members 26. The second side 54 of each tooth 60 is in engagement with an elongated rotatable cam bar or member 62 whose axis of rotation lies in plane 34.
While the cam member is in the first position (FIGS. 3 and 4) the circuit board 46 is inserted between the two rows of contacts 26 (FIG. 4). As seen there is space between the contact portions 42, 42 greater than the thickness of board46 and circuitry 44' thus allowing a zero-insertion force. After the board 46 is in position (FIG. 4) the cam member 62 is rotated forcing contact portions 42 the board 46 (FIG. 5).
