Abstract: A connector for a printed circuit board has a printed circuit board having a cut-out portion at one corner of its inserting end side and a plurality of contact points or conductor strips juxtaposed along a marginal portion of its inserting end and a connector body having a groove through which the printed circuit board is inserted and withdrawn. The groove is provided therein with a plurality of contacts which are arranged in such a manner as to be resiliently contacted with a group of the contact points. The connector body is provided with a single push-up lever for pushing up one side of the printed circuit board. The single push-up lever is pivotally supported on one end portion of the connector body. The push-up lever is provided with a push-up portion adapted to engage with the cut-out portion of the printed circuit board. The cut-out portion is given a push-up force by the push-up portion resulting from pivotal movement of the push-up lever.

Abstract: A front plug system with a lagging end contact arrangement. The front plug system for flat components includes a front element (1) with front plug connector (20) which can be plugged on by a swinging motion. If the front plug connector is plugged on until the point of engagement of a closing arrangement (27, 15) is reached, all operating contacts of the front plug systems arranged in receiving arrangements (3, 24) are already closed. An end contact arrangement (51, 52) arranged opposite the center of rotation of the front plug connector engages only when, after operating the closing arrangement, the front plug connector is plugged completely onto the front element and secured against being pulled off. With the end contact arrangement according to the invention the electrical signals of the operating contacts can be released simultaneously in particular across a control on the flat component.

Abstract: A connecting apparatus is provided for removably attaching a first member to a second member. The first and second members include respective mating surfaces which mate with each other. A pivot arm is situated adjacent one end of the mating surface of the first member. A jack screw is retained adjacent the remaining end of the mating surface of the first member. The jack screw includes a threaded end which extends from the mating surface of the first member and which faces the second member. The second member includes a pivot structure adjacent one end of the mating surface of the second member. The pivot structure of the second member permits the first member to pivot about the pivot structure when the pivot arm of the first member is removably engaged in the pivot structure. A screw captivating structure is situated in the second member for captively engaging the jack screw when the mating surface of the first member is pivoted toward and mated with the mating surface of the second member.

Abstract: A two-piece rotating contact zero insertion force connector is used to interconnect printed circuit boards (daughter boards) to backplanes (mother boards), cables to panels or cables to cables. This is accomplished by rotating one-half of the mating contacts relative to the other half to complete the necessary electrical connection. A number of different rotating contact designs are included which could be utilized to implement the overall concept.

Abstract: An improved plug-and-receptacle electric connector arrangement designed such that in mating the plug connector and the receptacle connector, the plug connector is inserted at an angle within the receptacle connector until the front end of the plug has reached the rear end of the entry space of the receptacle connector. The plug connector is rotated about a fixed point of the receptacle connector until the plug connector has been put in alignment with the receptacle connector. Then, both mechanical and electrical connections are established between the mating units.

Abstract: Electrical connector assemblies comprising a housing and a plurality of contact pins engaged therein, the pins having spaced flexible contact arms adapted to receive and be flexed apart by an electrical component such as a printed circuit card during the pivot attachment thereof. The contact pins have a spaced pair of lower contact legs and a spaced pair of upper contact arms, one of which is generally C-shaped and flexible in directions towards and away from the other to provide a flexible gap therebetween which, at rest, is greater than the thickness of the printed circuit card.

Abstract: An automating assembly for electrical installations comprises a plurality of input and output modules each detachably fastened to a respective modular module carrier removably attached to a support bar. The module carriers each include an integrated circuit connectable to the integrated circuits of adjacent module carriers by means of rigidly mounted plug strips and cooperating jack strips connected to the integrated circuits of the module carriers via flat flexible cables. Each modular module carrier is connected to a respective terminal block for the coupling of external wires to the automating assembly. The module carriers are designed to facilitate the removal of individual module carriers for applications in which a reduced number of input and output modules is required.
