The plastic parts include surfaces (26, 64) allowing a reverse displacement for wire removal. A multiple wire version including a common housing (90) is taught with multiple push buttons (50).

Abstract: A contact and terminal assembly having a block member, a conductor, and a securing member is disclosed. The block member and the securing member each define coacting curved surfaces between which the conductor is secured. The coacting curved surfaces define an appropriate angle for bending the conductor such that the conductor may serve on one end as a contact and at the other end as a terminal to which an electrical connection may be made. The block member, conductor, and securing member each include appropriate tabs and shoulders such that the three items may be appropriately interlocked to be affixed to each other.

Abstract: An adaptor is provided for effecting a small radius-of-curvature bend in a relatively large diameter coaxial cable. The adaptor comprises a central, preferably plastic, bellows-like protective element, at either end of which is attached a connector for attachment externally to a relatively large diameter coaxial cable, each connector attached internally to a flexible, relatively small diameter coaxial cable which extends from one connector to the other connector through the protective bellows-like element. Because of the bellows-like element and the relatively small diameter of the flexible coaxial cable in the adaptor, a small radius-of-curvature effective bend in the relatively large diameter coaxial cable assembly can be achieved without significant transmission losses.

Abstract: A connector bank for cable wires (2,3,4) of telephone cables such that two cable wires (2,4 or 3,4, resp.) connected with each other over the connector bank can be separated from each other, with no need to loosen the respective contact connections.

An outer molding of synthetic resin (33) surrounds tubular metal components (16, 12, 8, 10, 9) of the terminal, and a concentric inner molding 32 isolates the outer and inner sheaths (13, 17) of the cable (7). Within the terminal (6), the insulated conductors (19) which emerge from the end of the cable are spaced from one another, and traverse an insulating sealing plug (20) inserted in a watertight manner inside the tubular metal components (8, 9).

Abstract: A substantially U-shaped electric connecting terminal wherein a plate-like web is flanked by and is integral with two sidewalls. The web has a centrally located partly circular opening and two sector-shaped springy lugs which extend into the opening. Each sidewall has an outer panel which is integral with the web and an inner panel which is integral with the respective outer panel and carries a springy lug which overlies a portion of the opening. The dimensions of the lugs are selected in such a way that, when the web is impaled on a cylindrical or polygonal stud of a support for the terminal, the tips of the lugs frictionally engage the peripheral surface of the stud and hold the terminal in a selected position with reference to the support. The lugs of the sidewalls alternate with the lugs of the web and define therewith slots which extend radially of the opening.

Abstract: A telephone modular jack includes a base for receiving thereon a contact block carrying an array of spring contacts, the corresponding number of terminal units, and a cover, all mounted downwardly upon the base to be capable of being assembled by an automated technique. Each of the terminal units has a lug which is press-fitted to each one of lead tabs extended from the spring contacts when the contact block is mounted on the base. Each spring contact has a first end portion, a middle portion, and a second end portion, the portions being bent with respect to the others. The contact block includes a upright support and a horizontal support in parallel with the base. The middle portion of each spring contact is molded in the upright support in such a manner as to project the first end portion from the top of the upright support diagonally downward to the base, while the second end portion extends through the horizontal support and projects therefrom to define the lead tab at its end.
