Abstract: A plug-in connector has a plug member and a locking device for securing the plug member on a counterpart. The locking device has at least one locking element having a release position and a locking position, wherein in the release position the plug member is removable from the counterpart and wherein in the locking position the plug member and the counterpart are locked relative to one another. An actuating element acting on the locking device is provided for moving the at least one locking element from the release position into the locking position in a radial direction relative to a longitudinal axis of the plug member.

Abstract: A contact clip for an insulated, multi-strand electric cable has first and second clip parts engaging one another. The first clip part has a receptacle for correctly positioning the cable and the second clip part has contact pins assigned to a strand of the cable, respectively. The contact pins pierce the cable insulation and electrically contact the strands of the cable. They are positioned transversely to a longitudinal cable direction adjacent to and at a spacing from one another. This spacing matches the strand spacing. The receptacle is wider than the cable in the transverse cable direction. A fitting member is inserted into the receptacle for determining a lateral position of the cable in the receptacle. A first contact pin, depending on the lateral position of the cable within the receptacle, either engages one of the strands of the cable or the fitting member.

Abstract: A connecting plug for connecting an input/output unit to a machine control with a central bus, wherein the input/output unit is to be connected to a multi-strand electrical cable connected to a bus node, has a housing with a first plug connection for an incoming cable and a second plug connection for an outgoing cable. The incoming cable is looped through to the outgoing cable forming a looped-through cable. The housing has a connector for the input/output unit. An electronic device is arranged in the housing and connected to the connector. The connector is connected by the electronic device to the looped-through cable.

Abstract: A printed circuit board arrangement for printed circuits with electronic components has a first board having a first electric partial circuit and having a first edge formed as a first contact comb with successively arranged first projections and first cutouts. A second board having a second electric partial circuit and having a second edge formed as a second contact comb with successively arranged second projections and second cutouts is provided, wherein the second contact comb is configured to be complementary to the first contact comb. The first and second boards are combined to form a complete circuit with the first and second boards substantially positioned in a common plane. The first projections engage captively the second cutouts, and the second projections engage captively the first cutouts.
