Abstract

To permit, selectively and in accordance with safety or standardization rirements, connection of different electrical supply devices, such as extending cables or terminal posts, pins or clamps, to a single, standardized operating or accessory circuit retained on a circuit board (2) within a housing (1), the housing is formed with a connection receiving portion (5a) selectively differently constructed connection parts (3, 3') forming insert elements are provided, dimensioned and shaped to fit into the receiving portion of the housing. The connection parts, forming the insert element, thus can be constructed according to the respective safety or standardization requirements without otherwise affecting the structure of the substantially more expensive operating or accessory circuit in the housing. A strain relief can be integrated with the construction, for example secured to the housing and/or the connection part to clamp wires or cables projecting from the housing, attached to terminal pins, posts or clamps of one form of connection part, or directly from another form of connection part.
