Description
- This invention relates to electrical connectors and, more particularly, to electrical connectors for use with printed circuit boards and telephone plugs.
- It is often desired to provide a direct readily interchangeable electrical connection between external input devices, such as telephone plugs, and internal system devices, such as prated circuit boards. In the past such a connection has typically been accomplished by two connector assemblies indivi- dually mounted using a printed circuit back panel or a chassis/cabling interface. This arrangement is relati- vely expensive since two separate connector assemblies are required as well as interfacing hardware. This arrangement also creates a rather long electrical signal path, with consequent opportunity for signal degradation, and results in a rather high volume package, rendering it difficult to use where installation space is at a premium.
- It is an object of the invention to provide a compact and inexpensive electrical connector providing a direct readily interchangeable electrical hardware connection between telephone plugs and printed circuit boards.
- The electrical connector according to the invention includes a housing of insulative material defining an elongated slot adapted to receive an edge of a printed circuit board and a socket adapted to receive an electrical plug having a plurality of electrical terminals. A plurality of elongated electrical contacts of conductive springy material extend side by side within the housing generally between the housing slot and the housing socket, Each contact includes a circuit board engaging section defining a generally flat wiping portion positioned at one side of the housing slot and operative to resi- liently and wipingly engage a respective contact on the edge of a printed circuit board inserted into the slot, and a plug engaging section defining a tail portion projecting in cantilever fashion into the socket toward the blind end of the socket and at an angle with respect to the line of action of the socket. With this arrangement, printed circuit boards may be interchangeably inserted into the housing slot for resilient engagement by the wiping portions of the contacts and multi-terminal plugs may be interchangeably inserted into the housing socket for resilient wiping engagement by the tail portions of the contacts with the tail portions resiliently pivoting to a spring loaded contact position as the plug seats in the socket.
- According to a further feature of the invention, the contacts include upper and lower contacts having the wiping portions of their circuit board engaging sections respectively arranged to contact the upper and lower surfaces of an entering circuit board and the tail portions of all the contacts are arranged, cantilever fashion, in the housing socket in side-by-side lateral alignment.
- According to another feature of the invention, the lateral spacing between each contact tail portion is significantly less than the lateral spacing between each contact wiping portion and the contacts are dissimilar and are configured so that, ta.ken as set, they neck down between the wiping portions and the tail portions to accommodate the disparity in lateral spacing.
- In the disclosed embodiment of the invention, the circuit board slot opens in the front face of the connector, the plug socket opens in the rear face of the connector at a location generally above the slot location, and the plug engaging sections of the contacts extend rearwardly through passages in the housing to a location on the rear face of the housing below the socket, thereafter bend upwardly through a right angle to the lower edge of the socket and thereafter bend forwardly in cantilever fashion into the socket.

- The invention electrical connector, broadly considered, comprises a
housing 10 and a plurality of contact assemblies 12 extending within the housing. -
Housing 10 is formed of an insulative material such, for example, as nylon 6/6 U.L. Rated 94 V-0, 30% glass filled; or ZytelFR 50 U.L. Rated 94 V-0.Housing 10 may be monolithic or multi-piece. In the disclosed monolithic form,housing 10 is bounded by a plurality of generally planar surfaces including afront surface 14, arear surface 16, an insetrear surface 17, atop surface 18, abottom surface 20,forward side surfaces rearward side surfaces 26, 28 and a plurality ofchamfered surfaces circuit board slot 46 opens infront housing face 14 and atelephone plug socket 48 opens inrear housing face 17.Slot 46 extends laterally acrossfront face 14 and rearwardly within the housing toblind end wall 50. The entrance toslot 46 is chamfered at 46a to facilitate insertion of a printed circuit board. A series oflower notches 52 open infront housing face 14 at laterally spaced locations thereacross and a series ofupper notches 54 open infront housing face 14 at laterally spaced locations that are staggered with respect tolower notches 52. The foward portions oflower notches 52 open at their upper sides inslot 46 and the forward portions ofupper notches 54 open at their lower sides inslot 46. The rearward portions oflower notches 52 pinch inwardly and terminate in rearwardly extendinglower passages 56. The rearward portions ofupper notches 54 pinch inwardly and terminate in rearwardly extendingupper passages 58. Upper andlower passages rear housing face 17. A plurality of parallel verticalopen grooves 60 are formed inface 17. Eachgroove 60 communicates at its lower end with the rear end of arespective passage socket 48. Sinceupper passages 58 open inrear face 17 at a location above the rear face opening oflower passages 56, thegrooves 60 communicating withupper passages 58 are foreshortened relative to thegrooves 60 communicating withlower passages 56.Grooves 60 respectively communicate at their upper ends with the rear ends of a plurality of parallel forwardly extending open grooves 64 formed in socket bottom wall 62. Integralpivotal latch members 65 of known construction are provided at the top and bottom ofhousing 10 to facilitate attachment of the housing to a suitable mounting surface or structure. - Each contact assembly 12 includes a circuit board engaging piece or
section 66 and a plug engaging piece orsection 68.Pieces 66 are formed of conductive resilient strip material andpieces 68 are formed of conductive resilient rod or wire material. The inboard or rearward end of eachstrip piece 66 is joined to the inboard or forward end of eachwire piece 68 by crimping or welding. - Four
upper contact assemblies 12a, 12b, 12c, and 12d are provided as well as four lower contact assemblies 12e, 12f, 12g, and 12h. Upper contact assemblies 12a, 12b, 12c, and 12d are positioned inhousing 10 with eachstrip piece 66 positioned in anupper notch 54 and eachwire piece 68 extending rearwardly through anupper passage 58, then upwardly in avertical groove 60, and then forwardly and upwardly to define atail portion 70.Tail portions 70 project in cantilever fashion intosocket 48 toward the blind end 48a of the socket and at an angle with respect to the line of action 48b of the socket. Lower contact assemblies 12e, 12f, 12g, and 12h are positioned inhousing 10 with eachstrip piece 66 positioned in alower notch 52 and eachwire piece 68 extending rearwardly through alower passage 56, then upwardly in avertical groove 60, and then forwardly and upwardly in cantilever fashion intosocket 48 to define atail portion 70. The upwardly extending portions of the wire pieces of the upper contact assemblies are foreshortened relative to the corresponding portions of the wire pieces of the lower contact assemblies so that thetail portions 70 of all of the contacts are positioned side by side in lateral alignment withinsocket 48. - Each
strip piece 66 includes awiping portion 72 projecting upwardly or downwardly intoslot 46. The rearward tip 74 of eachwiping portion 72 is spring loaded against the adjacent housing surface to provide a preload for the wiping portion. Atab 76, struck from eachstrip piece 66, seats in agroove 78 in the bottom or top, respectively, of eachnotch - The lateral spacing between the wiping portions of adjacent upper contact assemblies or between the wiping portions of adjacent lower contact assemblies (for example, as viewed in Fig. 1 between the centerline of the wiping portion of lower contact assembly 12e and the centerline of the wiping portion of lower contact assembly 12f) is significantly greater than the lateral spacing between the respective tail portions of these assemblies. For example, the spacing between
adjacent tail portions 70 insocket 48 will typically correspond to the standard .040 inch spacing between adjacent terminals 80 on astandard telephone plug 82 so that the spacing between the tail portions of adjacent upper or adjacent lower contact assemblies will be .080 inches. By contrast, the spacing between adjacent upper or adjacent lower wiping portions will correspond to a standard spacing for theconductive strips 84 on a printed circuit board 86. Whereas various standards are used for the lateral spacing of the conductive strip on a printed circuit board, all of the common spacing standards (for example, .150 inches or .109 inches) exceed the spacing (that is, .080 inches) between every second terminal on a standard phone plug. - To accommodate this spacing disparity, the contact assemblies are made in sets of dissimilar assemblies. Thus, as best seen in Fig. 4, the four upper contact assemblies each have a unique strip piece. Specifically, as viewed from the rear of the connector in Fig. 3, the center line of the wiping portion of the strip piece of
assembly 12a is offset sharply to the right of the centerline of the inboard end of that strip; the centerline of the wiping portion of the strip piece of assembly 12b is offset slightly to the right of the centerline of the inboard end of that strip; the centerline of the wiping portion of the strip piece of assembly 12c is offset to the left of the centerline of the inboard end of that strip by a distance slightly greater than the opposite offset of the strip of assembly 12b; and the centerline of the wiping portion of the strip piece of assembly 12d is offset to the left of the centerline of the inboard end of that piece by a distance slightly greater than the opposite offset of the strip ofassembly 12a. The upper contact assemblies, taken as a set, thus neck down between the wiping portions and the tail portions to accommodate the disparity in lateral spacing between the wiping portions and the corresponding tail portions. A matching set of dissimilar strip pieces, rotated 180°, is used as the strip pieces for the lower contact assemblies. Specifically, the contact strip forassembly 12a, when rotated 180°, is usable as the strip piece for assembly 12h. The strip pieces for assemblies 12b and 12g, 12c and 12f, and 12d and 12e are similarly interchangeable. - The
invention connector 10 allows ready and interchangeable electrical connection between anyselected telephone plug 82 and any selected printed circuit board 86. Specifically, when it is desired to establish a direct electrical hardware connection between a selectedtelephone plug 82 and a selected printed circuit board 86, the plug assembly is plugged intosocket 48 and the printed circuit board is plugged intoslot 46. As the plug moves intosocket 48 along line of action 48b, plug terminals 80 wipingly engagecontact tail portion 70 and resiliently pivot the tail portions to their spring loaded contact positions as the plug seats in the socket. Withplug 82 seated insocket 48,tail portions 70 seat in grooves 64 andshoulders 84 on a standard resilient latch 86 onplug 82 coact in known manner with shoulders onhousing 10 to preclude inadvertent removal of the plug from the socket. As printed circuit board 86 entersslot 46, the wipingportions 72 of the upper and lower contacts resiliently and wipingly engageconductive strips 84 on the upper and lower surfaces, respectively, of board 86. - The invention connector will be seen to provide a compact and inexpensive device for providing direct and readily interchangeable electrical hardware connection between telephone plugs and printed circuit boards.
