Definitions

  • This invention is concerned with solderless wireconnectors, such as may be used for splicing or permanently connecting together bare or insulated copper or aluminum wire conductors in telephone and other electrical circuits,
  • solderless wireconnectors such as may be used for splicing or permanently connecting together bare or insulated copper or aluminum wire conductors in telephone and other electrical circuits
  • One application for which the connectors of the invention are particularly well adapted is the splicing of plastic'covered copper wires of the same or different diameter in telephone cable junctions. Larger diameter wires are also conveniently and permanently connected by means of connectors constructed in accordance with the principles of the invention.
  • connection is permanent and is not loosened by repeated mechanical stresses, temperature or pressure changes, exposed to moisture, or passage of electrical current; and the initial low resistance is maintained. No preliminary stripping of insulation is required.
  • the connector penetrates and displaces the plastic, paper or other insulating covering during application, making and maintaining a positive metal-to-metal juncture. Twisting and soldering operations are avoided. No special tools are required, the connector being applied to most wire-sizes by means of common pliers or side-cutters.
  • the connector provides its own insulating covering, and positively indicates the completion of the connection.
  • the connection is permanent under all operating conditions, the connector may if necessary be removed and re-applied.
  • the connector is further characterized by simplicity of construction and manufacture.
  • FIGURE 1 represents a View in perspective, with portions cut away, of a preferred form of the connector as employed in the joining of insulated copper wires in telephone circuits;
  • FIGURE 2 is a plan View of a conductive metal blank as used in producing the connector of FIGURE l;
  • FlGURES 3 and 4 illustrate the metallic connector component in partial elevational view in two stages of application to an insulated wire shown in section
  • FIGURE 5 is a cross-sectional view taken at the position of section 55 of FIGURE 1 after application of the connector in the joining of wire-ends.
  • the connector of FIGURE 1 comprises an insulating base 11 provided with longitudinal tubular passages 12, 13, 14 for insertion of Wire-ends to be connected, and
  • FIGURE 1 having a slotted, generally U-shaped, conductive member 15 supported within an insulating cap 22 movably tion indicated in FIGURE 1 by means of inner ridges 23 on opposing sides of the cap in cooperation with upper grooves 24 in the inner walls of the base 11, illustrated in FIGURE 5.
  • the U-shaped connector member 15 is conveniently formed from a fiat slotted plate 30 as shown in FIGURE 2, wherein the opposing jaws defining the slots 17, 19 are shown to be substantially parallel over the inner closed portion of the slot and to be gradually divergent toward the open end.
  • Inner fold lines 25 indicate the juncture between the leg portions and the central portion of the completed connector member 15.
  • FIGURES 3 and 4- Two stages in the formation of a permanent positive electrical connection between the connector member and an insulated copper wire are indicated in FIGURES 3 and 4-.
  • the insulated wire comprising a copper conductor 35 with its insulating covering 37, is shown as it enters between the divergent end portions of the opposing jaws defining the slot 17, As pressure is applied, the conductor is forced into the slot 17, and the jaws first penetrate the insulating covering 37 and then contact and eventually partially deform the copper core 35. At the same time, the jaws are forced apart from their initially substantially parallel relationship to a relatively slightly angular position as in FIGURE 4, in which position the jaws impart continual pressure against the conductor 35 due to the resiliency of the material of which the leg 16 of the connector member is constructed.
  • the wire may enter the slot formed by the initially parallel opposing jaw portions to a greater or lesser distance. In all cases, however, the conductor 35 should be completely within the initially parallel jaw area and should be somewhat below the closed end of the slot.
  • FIGURE 5 shows the configuration of the connector of FIGURE 1 at section 5-5 after it has been applied in connecting a plurality of conductors.
  • the upper surface of the cap 22 is now flush with the upper surface of the thickened upper portion of the base 11, and is held in position by means of the ridges 23 fitting within corresponding lower grooves in the interior surface of the base member 11.
  • the extended edge of the leg 18 of the connector member 15 fits within the groove 21, and the conductors 35 are shown to be forced well into the corresponding slots.
  • the U-shaped connector member 15 is retained within the plastic cap 22 in the specific structure here shown, by plastic ridges 38 extending from the interior side walls of the cap between the legs 16 and 18,
  • the width of the slots 17 is somewhat smaller, along the inner parallel portion, than the initial diameter of the copper conductor to which connection is to be made. It will also be appreciated, in view of the foregoing description, that the thickness of the connector member 16, the hardness, tensile strength and resiliency of the material of which it is constructed, and the distance between the closed end of the slot 17 and the adjacent fold line 25 of the connector member 15 must all be selected, with respect to the properties and dimensions of the wires to be connected, so as to insure that the entry of the conductor into the slot under pressure will not only force the opposing jaws through the insulating covering and into the metallic conductor but will also cause slight but significant separation of the jaw surfaces. Under these conditions, the jaw surfaces do not themselves deform; they make positive metallic contact with effective areas of the conductor surface;
  • the connector member 15 is formed of 0.025 in. (No. 22 B and S gage) cartridge brass; the slots 17 are each 0.013 inch in width memberand wires. 7 or substantially to, their original parallel positions, due
  • the connector of FIGURE 1 is particularly useful for connecting together a plurality of wire-ends; and for this purpose the tubular passages 12-14 need extend from the open end only slightly beyond the rearward leg portion 18 of the connector member 15. in the form illustrated, the tubular passage extending throughout the length of the base 111 permits contact with the conductor at both ends of the connector or alternatively permits interconnecting of two wire-ends entering the same tubular passage from opposing ends. Thus, up to six wire-ends may be interconnected with a connector asillustrated in FIGURE 1.
  • Suitable soft plastic insulating materials such as polyisobutylene or silicone greases, which completely fill all interstices within the closed connector and effectively prevent any subsequent entry of liquid Water or of corrosive vapors.
  • Plating the connector member with corrosion-resistant metal is also contemplated.
  • the connector 10 of FIGURE 1 will be seen to provide a completely enclosed and completely insulated permanent connection. It is, of course, possible to form a simple and effective means of applying the necessary stresses, and is preferred. Where additional stress is de sired, the plate of which the connector member 15 is constructed may be substantially thickened, in which case it may be necessary to reduce the thickness of the jaw surface so as to provide increased unit pressure on the conductor inserted therebetween; and the jaw surfaces may in such instances be hardened to resist such increased unit pressure. Alternatively, where somewhat less stress is required, or where the base portion of the plate 30 between the fold lines is significantly thicker than the leg portions 16 and 18, additional springiness or resiliency may be provided the jaw members, e.g. by
  • the U-shaped member 15 may be replaced by a single slotted flat or curved plate, an outer portion of which may be designed for connection to binding posts or other connection or support members.
  • means other than the body member 11 may be provided ,for applying pressure to a wire at bothsides of the slotted connector-member in forcing the wire between the opposing jaws.
  • the connector member and associated pressure-applying member may both be made of metal, the whole then preferably being enclosed in a flexible plastic open-ended insulating cover. Where subsequent removal of the connector may be desirable, the cap 22 and body 11 of the connector of FIGURE 1 are so constructed as to permit entry ofa suitable blade for prying the cap and connector-member from the body- The opposing jaws then return to,
