The invention relates to a housing comprising a terminal block intended to receive at least one end of a multi-strand cable and therefore comprising at least one recess (6a, 6b, 6c, 6d) for receiving the end of the cable, the recess being provided with a wall (8) in which an opening (7a, 7b, 7c, 7d) is arranged and through which the end of the cable extends during use, and a flank (10a, 10b, 10c, 10d) arranged opposite the wall with the opening, at least one surface of the flank facing the inside of the recess being rough in order to limit the risk of at least one strand detached from the end of the cable sliding through a space between the flank and the rest of the housing.

In various representative aspects, an apparatus for securing solar panels to a rail support guide, while facilitating grounding by a common grounding wire. The apparatus is an electrically conductive lay-in-lug fastener, which facilitates multiple rows of solar panels to be electrically bonded to each other. The apparatus includes a lug member for securing the grounding wire. In doing so, the structure for securing the grounding wire is at an acute angle to the frame, enabling a wrench to be used even in space-challenged locations.

The invention relates to a plug connector contact carrier (1) for selectively populating with electrical crimp contact elements (10) or electrical screw contact elements (20), comprising a plurality of contact chambers (2) for the contact elements, which contact chambers are provided in a contact grid, wherein the contact carrier has insertion openings (11) for inserting the contact elements into the contact chambers and wherein furthermore the contact chambers are property designed in such a way that selectively either a crimp contact element or a screw contact element can be inserted into and mounted in the contact chamber.

Wiring arrangement at wall edges and corners with decorative effect, having at least two elongated wire guiding strips; each wire guiding strip is positioned at a wall edge between a wall and a floor or a wall edge between two adjacent walls; each wall edge between the wall and the floor or each wall edge between two adjacent walls is provided with only one of the wire guiding strips; a corner connector is provided between two ends of two adjacent wire guiding strips to achieve electrical connection and a change in direction of the wiring arrangement; the corner connector has two legs electrically connected to two ends of the two adjacent wire guiding strips respectively; each of the wire guiding strips has a soft PVC wrapping layer and wires wrapped inside. The wiring arrangement has a reasonable structure and is safe and aesthetically pleasing.
