Abstract: A modular connector system includes at least one connector frame composed of a plurality of frame members which can be connected to each other, preferably by means of screws. A plurality of insulating members are secured in the connector frame. Each insulating member has two outer contact surfaces which extend approximately parallel to each other. A plurality of insulating members are arranged next to each other in a row with the outer contact surfaces resting against each other. Each insulating member also has at least two outer holding surfaces which extend transversely of the contact surfaces and are provided with holding projections. The distances between the holding surfaces of all insulating members are equal. The outer holding surfaces are engaged by two of the frame members of the connector frame which extend parallel to each other, such that a movement of the insulating members transversely of the plane of the connector frame is excluded.

Abstract: The inventive contact socket serves to connect flat contact tongues as are used in plug-type connection devices for testing purposes, in particular in the manufacture of automobiles. The contact socket (1), which permits frequent plug-in cycles with small insertion forces being required, comprises a contact spring support with two bearing walls (2, 3) which are essentially parallel to one another. Said bearing walls (2, 3) are furnished on the inner side, preferably on both inner sides, with a respective row of contact springs (4) being curved such that a gap (5) opening elastically, with contact being established, when a flat contact tongue is inserted, is formed by the regions that are curved toward one another. The ends (6, 7) of each contact spring (4) are bent back toward one another on the outer side of the associated bearing wall (2, 3). The two bearing walls (2, 3) are interconnected via a transverse wall (12) determining their mutual spacing.

Abstract: A contact pin and bushing assembly has the contact pin and a pin support, which limits the degree of insertion of the contact pin into an aperture in a circuit board, formed as separate items which are clamped together by the back end of the pin being pressed into a bore in the support. The pin support is provided at the base of the contact bushing.

Abstract: A water-cooled, high-current docking plug-connector device designed particularly for automatic welding machines has a plug socket component (1) with elastic contacts (4,6) and a plug pin component (2) for insertion into the socket component (1), so that the components can be rotated relative to each other. In order to transmit high current with low voltages, without the danger of the elastic contacts lifting out of position, several contact ring groups (3) are positioned in axial succession within the plug socket component (1), each of which ring groups (3) has at least one slotted outer socket contact ring (4) with a contact surface (5) resting elastically on the inner surface of the plug socket component (1), and at least one slotted inner socket contact ring (6) with a contact surface (7) which, in the inserted condition, rests elstically on the plug pin component (2).

Abstract: A contact pin - contact bushing unit comprises a contact pin (3), having two spring-mounted, parallel legs (6) bordering an elongated hole formed by punching. The legs are employed for insertion into the opening of a circuit board. The legs (6) terminate in a shoulder (7) which serves to demarcate the insertion path. The contact bushing is formed by a contact spring bushing (2) with several contact springs (8). The contact springs extend roughly from the area of a clamping shoulder (8), which determines the fixture point of one of their ends, at a distance from the bushing axis to the area of the front pin insertion hole (13). In an intermediate area of the contact bushing, the contact springs display the shortest distance from the bushing axis. The shoulder bordering the contact pin insertion path is formed by the indicated clamping shoulder (7) of the contact spring bushing (2).

Abstract: A cinch plug for connection to an electrical cable in audio or video systems has a contact pin and surrounding contact bushing each of which are formed of curved circumferentially disposed axially extending contact springs.

Abstract: An electrical plug and socket connector includes a two-part connector frame (1) which can be affixed to an apparatus housing, and further includes a two-piece insulating body (4, 5) enclosed between the two frame parts (2, 3), which insulating body has a plurality of bores to accommodate contact elements (6, 7) in the form of plug pins, plug sockets, or the like, which contact elements are connectable to electrical conductors on the rear side of the connector. The insulating body includes a frontwardly disposed supporting and guiding plate (4) fabricated of thermoplastic plastic. The insulating body also includes a rear plate (5). In order to achieve a trouble-free seal, the rear plate of the insulating body is in the form of a sealing plate (5) of rubberlike elastic material, and this sealing plate (5) is particularly dimensioned with respect to the supporting and guiding plate (4), which supporting and guiding plate rests against the outwardly curved or flared flange (12) of the front part of the frame.

Abstract: An electrical contact device for transmitting high electric current includes a cylindrical contact pin (2) and a spring-loaded contact jack (1) for receiving the pin. A plurality of essentially axially parallel spring-loaded contact elements are provided which extend axially on the cylindrical inner wall of the jack. In order to allow contact over large tolerances between the contact pin (1) and contact spring jack (2), the jack is provided with intermediate spring contact elements (4,5) between it and an outer sleeve body (3) is which the jack is mounted with spring-loading both axially and radially.

Abstract: The contact element for an electrical plug connector has a plurality of contact springs disposed side by side, each such spring being a segment of a contact spring wire, one end of which is attached to a bearing piece. Each such spring has, in its middle region, a contact locus which provides contact with a cooperating contact piece. In order to substantially simplify the structure from a manufacturing engineering standpoint, a single structural unit is formed from a first metal strip which forms the bearing piece, a plurality of spacing members connected to the bearing piece and extending parallel to each other, and a second metal strip parallel to the first, which second strip forms the support piece.

Abstract: A contact element in the form of a spring contact jack or spring plug pin has a plurality of mutually laterally disposed spring contacts which can be attached at one end to a support piece and which are radially curved in order to provide contact with an opposing contact; and further relates to a method of manufacturing the contact element.
