Abstract: A plug connector has a male plug part, connected to an electric connecting cable and having contact elements, and a female plug part with matching counter contact elements providing electric contact in a contact position established when the male plug part is inserted into the female plug part. The female plug part has a sleeve-shaped housing having an inner circumferential surface with a locking edge. The male plug part has a locking sleeve and an outer sleeve axially slipped onto the locking sleeve. The outer sleeve has locking tabs engaging the locking edge in the contact position. The locking sleeve has several tongue-shaped thickened portions distributed circumferentially that have radially outwardly positioned cone-shaped locking surfaces. The locking tabs are spaced circumferentially from one another by a spacing that allows the thickened portions to pass between the locking tabs when the outer sleeve is slipped onto the locking sleeve.

Abstract: An electronic component for mounting on a PCB by a reflow soldering method has a conductor element mounted on an insulating component body, the conductor element having a contact region exposed on the exterior of the component body to connect the component to the PCB. In order to increase the numerical mounting density of such electronic components on the PCB a window is provided in the body of the component, which allows IR radiation to pass through the component body to the contact region of the conductor element.

Abstract: An improved contact device uses a connector module (1) of U-shaped cross-section to electrically connect a liquid crystal display or other flat panel (4) with edge contacts to a printed circuit board (7). Lower cost and reduced profile height are achieved in that the contact elements (6) of the connector module are in direct electrical contact with corresponding conductors on the printed circuit board, and the topside of the connector module is lined with a soft elastomer layer (12).

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: 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: The method relates to manufacturing contact spring sockets with a plurality of radially inward bowed contact springs clamped at one end in an approximately cylindrical socket body, formed by a thin-walled deformable sleeve. After introduction of the straight contact springs into the socket body from one socket end, they are made fast by deformation of the socket material and their free ends are brought into supporting abutment on an annulus. This is associated with a mandrel for assisting assembly, which passes through it and which is during manufacture introduced co-axially into the socket body and finally withdrawn from it. Subsequently the mandrel together with the annulus is introduced into the socket body. The contact springs are then, by applying axial pressure on their ends, converted into a shape bowed into the interior of the socket until they abut the mandrel.

Abstract: A connector, for a multiconductor flat cable, composed of three rows of connection contacts mounted at a defined distance from one another in an elongate body of insulating material, with the connection contacts having the shape of sockets or pins which extend toward one surface or side of the insulating body. The connection contacts are each connected, via a center connecting section, with respective conductor terminals which are spaced slightly differently from one another than the associated connection contacts and each has the shape of a pair of contact fingers which extend approximately mutually parallel toward the opposite side or surface of the insulating body. The conductor terminals are longitudinally located such that each conductor of the flat cable will be pressed between a respective pair of contact fingers so as to pierce or displace the insulation surrounding the conductor and contact same.

Abstract: A method relates to manufacturing contact spring sockets with a plurality of contact springs, clamped at one end in an approximately cylindrical thin-walled socket body and bowed radially inward. The straight contact springs are introduced in the socket body into the annular space between a mandrel and the socket wall and subsequently when in an aligned state relative to each other are pressed against an annular head at the front end of the line connector which partly projects into the socket body and are made fast in this position at one end. Deformation of the socket body for elastically bowing the contact springs can be omitted according to the invention, if after introduction of the contact springs into the annular space of the socket body an insert ring (10) is introduced into the latter fitting adjacent the socket innner wall, whose internal diameter is smaller than the external diameter of the annulus plus twice the diameter of the contact springs.
