Abstract: A patchboard having multiple honeycomb components, each honeycomb component having a box-shaped housing with two end surfaces and four lateral surfaces which extend between the end surfaces. Each of the end surfaces has at least one connection region, and each of the lateral surfaces has at least one connection element for connecting to another honeycomb component. Individual honeycomb components can be removed from the patchboard in that at least one respective elastic latching arm with a latching hook is arranged on at least two mutually adjacent lateral surfaces of the honeycomb components. Each of the latching arms extends in the direction of the length of each lateral surface, and at least one recess is formed at least on the lateral surfaces on which at least one latching arm is formed, the recess being used to access the latching hook of a latching arm from an end face using a tool.

Abstract: A terminal device includes: a housing having at least one contact cavity; a contact part which is arranged in the at least one contact cavity and into which at least one electrical line can be plugged in order to make electrical contact with the contact part; and at least one busbar which is arranged on the housing, is electrically connected to the contact part, and a busbar portion of which extends along a height line. An end portion adjoins the busbar portion, which end portion extends in an oblique direction at an oblique angle to the height line and can be moved along the height line relative to the contact part.

Abstract: A terminal clamp is described. The terminal clamp includes a housing, a clamp pocket arranged in the housing into which a conductor to be clamped can be inserted, the clamp pocket having a base wall, and two side walls which are opposite each other, which extend away from the base wall, and which form a conductor guide channel, the conductor guide channel having, at least in regions in the longitudinal direction thereof, a cross-section which continually narrows towards the base wall, and at least one clamping spring protruding into the clamp pocket for clamping the inserted conductor in the clamp pocket.

Abstract: The invention relates to a spring-cage terminal block, having a bus bar and a leg spring for connecting a stripped conductor end piece of an electrical conductor, wherein the conductor end piece is inserted into a material passage of the bus bar and is clamped by means of the leg spring. According to the invention, the contact surface on the metal collar inner wall surface of the material passage has contact ribs extending along the insertion direction in order to form a linear contact pattern which extends in the insertion direction.
