摘要:
The invention is directed to an arrangement for simply and inexpensively attaching semirigid coaxial cable to suitable connectors in which the connector is provided with a sleeve having either internal fluting or cross threads. The effective internal diameter of the sleeve is only slightly greater than the external diameter of the outer conductor of the semirigid cable so that when the sleeve is crimped the flutes and/or threads bite into the outer conductor to form a connector-cable bond sufficiently resistant to pull-off, twisting and slipping, while at the same time forming a joint having an acceptably low radio signal power leakage through the crimped interface and so little dimensioning effect on the cable that transmission losses due to internal reflections are maintained acceptably low.

An electrical connector is disclosed for terminating semi-rigid coaxial cable, and comprises a grip ring having a continuous rearward end with multiple spline fingers extending forwardly therefrom and grooves on its inner surface, and a bored tubular shell member having a contoured internal diameter to accept the cable and the grip ring and grooves extending along an outer part of the bore of the shell member. The cable is drawn through the grip ring and the shell member, and as the grip ring is press inserted into a rearward end of the shell member, the spline fingers resiliently deflect inwardly along the shell member contour, and embed into the outer semi-rigid cable sheath to establish electrical contact therewith and the grooved bore score the outside surface of the grip ring during its movement into engagement with the cable sheath which causes the grooves of the grip ring to score the cable sheath, thereby providing antitorque connection therebetween.

A tool for wrapping insulated wire without first stripping or slitting the insulation is obtained by means of a novel bit configuration which crushes the insulation during the wrapping process causing the terminal corners to pierce and contact the wire core. Additional features include means for breaking the wire after wrapping, and means providing a continuous supply of fresh wire.

A continuous strip of thermoplastic articles, such as electrical connecting device housings, has first and second portions defined by bands which extend along the entire length of the strip. The first band is of a first thermoplastic material which has optimum properties and characteristics for the parts of the articles which lie in the first band and the second band is of a second thermoplastic material which has optimum properties and characteristics for those portions of the article which lie in the second band of the continuous strip. In the case where the articles are connector housings, the first band may be of a material which has superior crimping characteristics while the second band may be of a material having optimum firmness and strength. The strip is manufactured by a continuous thermoplastic molding process in which the two materials are continuously extruded through a nozzle and into an endless series of side-by-side cavities in a molding wheel while the surface of the wheel was continuously moving past the nozzle.

Modular connectors and associated adapter assemblies are disclosed for interconnecting telephones and telephone signal equipment. The modular connector and a mounting plate are structured so that the connector sidewalls with integral bosses and/or the apertured mounting plate are resiliently deformable to permit simple insertion and snap-locking of the connector and mounting plate.Various adapter configurations utilizing one or more modular connectors in unique system arrays for interconnection to non-mating signal equipment are also disclosed.

A three piece electrical contact assembly that includes an inner sleeve that is stamped and formed into a tubular shape from a flat sheet of metal. The electrical contact assembly provides a secure electrical and mechanical connection when crimped to a wire without the need for welding or brazing a seam (31) that results from forming the contact. The contact assembly includes: an inner sleeve having an enlarged middle portion (35) having forwardly and rearwardly facing shoulders for retention of the contact in a connector insert and a plurality of axially arranged slots (32) arranged in the wire receiving end of the contact assembly allow the contact assembly to distort symmetrically when a wire is crimped inside the contact; and a first and second outer sleeve (10,20) telescopically located over the front and rear portions, respectively, of the inner sleeve.

A carrier strip having a plurality of electrical terminals thereon is stamped and formed with alternating tab and recess portions. The carrier strip is adapted to be conveyed through an insertion machine which severs the terminals from the strip and inserts the terminals into a workpiece. To achieve closer spacing of the terminals and consequent increase in speed of terminal insertion within a workpiece, the carrier strip is adapted for stacking upon itself to provide multiple layers of carrier strips which are conveyed simultaneously to the insertion machine. For effective registration and interlocking of the stacked layers the carrier strip is purposely provided with a stamped and formed interlocking geometry. Multiple lengths of carrier strips according to the present invention may be conveyed simultaneously to an insertion machine where stacked registration is accomplished immediately prior to the insertion station of the machine.
摘要:
An electrical connector shielded contact assembly allows easy termination of coaxial cables by simultaneous crimping of coaxial cable conductors to the contact assembly in a single operation. Users installation comprises stripping of the cable to bare the inner and braided outer conductors, sliding of the inner and outer conductors respectively into and onto the contact assembly, slipping a ring over the braided outer conductor, and simultaneously crimping both the outer conductor and the inner conductor to the contact assembly. This operation is enabled by constructing the coaxial contact assembly from a stamped and formed outer contact configured as a housing utilizing dovetails on the seam for strength, an inner pin or socket contact, and suitable insulators therebetween. The housing and the inner contact have reliefs therebetween so that, when assembling an inner plastic dielectric component together with the inner pin or socket contact into place within the housing, the dielectric flows into the reliefs between the inner contact and the housing to form a stable and strong assembly. Windows in the outer housing permit subsequent simultaneous crimping of the inner and outer coaxial cable conductors respectively to the inner contact and the housing, with the inner crimp being aligned and protected by the dielectric component which serves the further purpose of controlling the differential span of electrical characteristics, that is, the dielectric constant, between the coaxial cable and the coaxial contact.
摘要:
An electrical connector for engagement preferably with relatively thin conductive material comprising, in one embodiment, a pair of generally planar interengaging members matingly arranged in spaced, opposing relationship. Each of preferably a plurality of preferably tapered piercing members selectively disposed adjacent a first surface of at least one of said members is arranged to penetrate through thin conductive material interposed between said members and extend into and be deformed about an associated selectively proportioned transverse aperture in the mating member as said members are compressively urged against the intervening conductive material, to establish a secure connection therebetween. Each of the members may be provided with one or more extending portions for coupling the connector to a further conductor or support member. Other embodiments include a multiple of spaced, interengaging members similarly comprising selectively disposed transverse apertures and mating piercing members.
