Abstract: Disclosed is a shielding of an electrically conductive material for use in a printed circuit board connector. The shielding is formed of at least two shield elements which each have at least two shield contact receptacles, at least two shield contact elements and at least one fastening structure for connection to a housing of the printed circuit board connector, and at least one printed circuit board contact for establishing an electrical connection to the printed circuit board to be contacted. The shield elements each have at least a first side element and a second side element which are interconnected by at least one intersection region.

Abstract: A plug is provided which has a main body and a sliding element, the sliding element encompassing the main body and being arranged thereon so as to be movable along a plugging axis of the plug, the plug having a blocking element which is arranged on the sliding element so as to be rotatable between an open position and a locked position, the axis of rotation of the blocking element being perpendicular to the plugging axis of the plug, or the plug having a blocking element which is arranged on the sliding element so as to be slidable between an open position and a locked position, the sliding axis of the blocking element being perpendicular to the plugging axis of the plug.

Abstract: An electric contact element for use in a printed circuit board plug connector is formed with at least two opposing narrow faces and at least two opposing wide faces. At least one narrow face is designed to be used as a contact surface in order to be brought into an electrically conductive connection with a counter contact element. At least the contact surface of the contact element and of the counter contact element are designed to have identical structures, and the wide face has at least one rigid region and a flexible region.

Abstract: An angled printed circuit board connector is suitable for connecting at least one circuit board to at least one additional circuit board or at least one corresponding circuit board connector. It comprises a housing, at least two contact elements which are arranged in pairs and have at least two narrow sides and at least two wide sides. The contact elements have at least one flexible contact region. At least the flexible contact region of the contact elements are substantially identically shaped. The housing is designed to orient the contact elements substantially parallel to the connected circuit board. Each contact has a rigid contact region that adjoins the flexible contact region. The rigid contact region has at least one fastening element for fastening the contact element in the housing. The rigid contact region forms at least one angle of 80° to 100°.

Abstract: A printed circuit board connector for connecting at least one circuit board to at least one additional circuit board or at least one corresponding circuit board connector, comprises a housing, at least two contact elements which are arranged in pairs and have at least two narrow sides and at least two wide sides, the contact elements having at least one flexible contact region, at least the flexible contact region of the contact elements being substantially identically shaped, the housing being designed to orient the contact elements substantially perpendicularly to the receiving circuit board, each contact having a rigid contact region that adjoins the flexible contact region, the rigid contact region having at least one fastening element for fastening the contact element in the housing.

Abstract: A contact element for establishing electrical contact between a first and a second printed circuit board is provided. The contact element has a fastening region for fastening to the first printed circuit board and a plug section for a plug connection to the second printed circuit board. The plug section has at least two contact arms which are electrically conductively connected to one another. A method for assembling a printed circuit board arrangement is also provided.

Abstract: In order to simplify mounting and cabling of optoelectronic plug connectors (3, 3?) and—equipped therewith—subdistribution units (6) and subdistribution systems, the use of special module housings (100) is proposed. The latter can accommodate a plurality of, in particular eight, identical and/or different optoelectronic transducers (2, 2?) and are installed in the plug connectors (3, 3?) between the electrical plug contacts (311) and the multi-core optical cables (58), i.e. the cores (51) thereof. Susceptibility to errors is considerably improved as a result and mounting is significantly simplified as a result of the improved clarity.

Abstract: In order to produce a circuit board plug connector in which the advantages of hermaphroditic plug connectors are combined with the advantages of conventional plug connectors, a contact carrier is equipped with both plug contacts of a first type and plug contacts of a second type in equal numbers. Advantageously, the plug contacts of the first type are designed as “male” contacts (blade contacts) and the plug contacts of the second type are designed as “female” contacts (fork contacts) and can be plugged into one another in principle.

Abstract: An electric plug connector has a locking element configured for releasably connecting to a mating plug connector, a housing for receiving at least one cable and at least one contact element, and a bending guard which is made of an elastic material and prevents excessive bending of the connected cable, wherein the bending guard can be used for different cable cross-sections for field assembly.
