Other combinations are possible depending on the desired connection type. In particular, two identical contact carriers become analogous to the embodiments described above 12 connected with each other.

Based on 14 and 15 Below is a particularly suitable manufacturing method for producing the contact carrier described above 12 explained. It is used to make the plastic holder 16 an injection molding tool used in the injection molding process, which comprises an injection mold, which in turn comprises two half-molds, which form a cavity in the closed state. By means of a relative to the cavity movable slide, which has a in 15 symbolically indicated by a black bar partition 80 forms, the cavity is reversibly divisible into two identical Teilkavitäten. Each Teilkavität is complementary to the plastic holder 16 formed. With inserted partition 80 thus become two plastic mounts 16 (as with the contact carrier 12 according to 14 shown) simultaneously.
