Description

The present invention relates to a cross connector according to the preamble of claim 1.

It is known to connect electrical contacts in juxtaposed terminal blocks of a terminal clamping arrangement by means of a contact tab of a cross connector with each other electrically conductive. Furthermore, it is known that in terminal blocks that are not to be connected by the cross connector, the contact tabs can be disengaged. The publication DE 42 23 540 A1 shows a cross connector having a marking device for each electrical contact in the visible upper edge region of a transverse bar of the cross connector. The marking device enables a reversible or irreversible arrangement or removal of a marking for each of the contact tabs. However, a loose mark may be lost and / or the installer may forget to place or remove the mark, such that in such terminal clamping arrangements, it is not certain that the electrical contact of one terminal through the cross connector is actually connected or disengaged from one or more adjacent terminal blocks taken.

The FR 2 190 319 shows a cross connector for a terminal block assembly having contact terminals, which are adapted to be contacted from the outside of the housing of the terminal to screw terminals. The actual cross connector is realized with an insulated line which has been stripped in the region of the contact terminals and around which the contact terminals are wound around. A mark is not provided on the actual contact terminals. There is also no housing on the cross connector. Between adjacent contact terminals, however, the cross-connecting line is surrounded by the conductor insulation.
