Description

May 12, 1964 K. H. POHL WIRE FORMED sowaauass MULTIPLE CONNECTOR Filed July 14, 1961 A TTORNEY United States Patent 3,132,913 WIRE FORMED SOLDERLESS MULTIPLE CONNECTOR Karl-Heinz Pohl, Summit, N..I., assignor to Bell Telephone Laboratories, Incorporated, New York, N.Y., a
corporation of New York Filed July 14, 1961, Ser. No. 124,101 4 Claims. (Cl. 339-97) This invention relates to solderless, electrical connectors.
In many applications, particularly in the telephone art, it is necessary to make multiple interconnections between small-diameter, insulated conductors in confined spaces where the use of screw-type terminal strips or similar connecting devices is undesirable. In addition, it is often difficult to effectively strip insulation from such small conductors without materially damaging the conductor surfaces or to hold them in position while connector components are manipulated to perfect fastening. The desirable features of known solderless connectors in this regard are offset by the number and size of components usually found in such connectors, or the alternative difficulty of tinning the contact surfaces of one piece, solderless connectors without materially inhibiting their ability to penetrate the insulation wall covering the conductor. Heretofore known methods of forming solderless connector structures from round wire stock overcome these difiiculties but are generally unacceptable in applications such as those regularly encountered in the telephone art where high connector to conductor interfacial contact pressures are essential in order to perfect a noiseless connection.
It is an object of this invention to provide high contact pressure, solderless connections which will have a low noise factor.
It is another object of this invention to provide conductor interconnections without the necessity of stripping insulation therefrom.
It is also an object of this invention to form an interconnection bank from electrically conductive wire stock which may be tinned without materially inhibiting its ability to penetrate conductor insulation walls.
Still another object of this invention is to perfect multiple conductor interconnectors with a minimum of manipulation in a limited physical space.
This invention achieves these objects by forming a series of pairs of parallel abutting wire sections from springy, electrically conductive wire stock such that the abutting surfaces are pressed against each other by the spring bias of looped sections formed from continuations of the wire stock and located at the ends of the abutting contact sections. This invention can be better understood by reference to the attached drawing in which:
FIG. 1 is a cross section through a connector block unit of one embodiment of the invention;
FIG. 2 is a perspective view of the connector shown in section in FIG. 1; and
FIG. 3 is a perspective view of another embodiment of this invention.
Referring first to FIG. '1, depicted therein is a cross section of an insulation block in which is imbedded a solderless multiple interconnector device 11 formed from a continuous filament of round, springy, electrically conductive wire stock, such as a bronze containing phosphorus. The extreme ends of this filament are formed into straight sections 14, 15 extending through the block perpendicularly to its top and bottom surfaces. Intermediate these straight sections are paired contact sections 18, 19; 21, 22; and 24, 25. Each of the sections has a common abutting surface with its associated pair member, and the members of each pair are separated from each other by closed loops 28, 30, 32 also formed from the same wire filament. The adjacent contact members of adjacent pairs (i.e. .19, 21; 22, 24) are separated from each other bysernicircular loops 35, 37 or, in the case of the endmost contact sections 18, 25 by semicircular loops 39, 41. When a conductor 43 is thrust between one of the pairs of contact members 21, 22, the contact members are actively forced toward each other through operation of the spring effect of the closed loop 30 and the open loops 35, 37 acting on opposite ends of the pair of contact members. This causes the facing surfaces of the contact sections 21, 22 to penetrate the insulation wall surrounding the conductor 43 and to come into firm physical and electrical contact with the conductor. The closure pressure on the upper ends of the contact sections 21, 22 established by the open loops 35, 37 is a function of the inherent springiness of the loop members augmented by the tendency of the outermost end of each of the open loops to resist positional dislocation due to its structural integration with the next adjacent contact members '19, 24 which bear against their associated contact pair members 18, 25. Similarly, the closure pressure on the upper ends of the endmost contact members 18, 25 is perfected by the inherent springiness of the open loops 39, 41 and their tendency to resist positional dislocation because of structural integration with the straight sections 14, 15. The closure pressure of the lower ends of the contact sections is established by the inherent springiness of the wire stock in the closed loops 28, 30, 32. The closure effect of these double cantilever structures acting on the ends of the contact sections of each pair causes the wire forming the contact sections to easily penetrate the insulation wall of an insulated conductor inserted therebetween, and to con-tact the conductor with great force, thereby establishing a firm, positive electrical contact. In addition, the insulated conductor tends to be retained in a location intermediate the ends of the contact sections due to the application of closure pressure at the contact section ends. This is a marked improvement over the heretofore utilized scissor effect of applying closure pressure fnom one end of a pair of solderless wire-formed connector contact surfaces, the natural tendency of which was to expel rather than retain the conductor, and in which high pressure contacts could not assuredly be maintained.
FIG. 2 illustrates several interconnector units 11 imbedded within the insulation block 10 parallel to each other and with their open loops located above the top surface of the block. The interconnector devices reside in slots 12 cut in the upper face of the block to accommodate them. The advantage of using such slots as opposed to totally surrounding the connector devices with the materi-al of the insulation block is in fully utilizing the augmenting effect of each adjacent contact pair operating through the open loop members.
FIG. 3 illustrates another embodiment of this invention wherein an interconnector device 11 similar to that illustrated in FIG. 2 is imbedded in a slot 12 in an insulation block 10 but is directly connected through a straight section 15 of the same wire filament to a second interconnection device 47 whose contact surfaces face degrees away from the contact surfaces of the first interconnection device. The second interconnector device 47 has its contact members 48, 49; 51, 52 and 54, 55 spaced so that they will readily accommodate and yet firmly bear upon the conductor paths 57, 59 of printed circuit boards 61, 62. Through use of this embodiment, a common electrical interconnection between the printed circuit boards 61, 62 and electrical conductors 63 inserted between the contact members of the first interconnector device 11 may be perfected.
It is to be understood that the embodiments of the invention herein set forth are only illustrative and that numerous other embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention.
