ABSTRACT:
A terminal block for receiving and terminating one or more conductors. The block comprises a housing of insulating material and screw-operated insulation displacement terminals (3) which are arranged in cavities (22) of the housing. Each terminal (3) includes a first contact member (4) which has an upper portion (5) containing a transverse opening (18) to accommodate one or more conductors. Furthermore, the first contact member (4) has a lower portion forming a downwardly extending pin (6) which extends through a base portion (14) of the housing and can be inserted into a plated-through hole of a printed circuit board. The terminal also includes a second contact member (7) forming a cage (8) which has on its top a threaded bore (11) for a screw (10). Furthermore, the second contact member (7) also has a transverse opening (17) which is aligned with the transverse opening of the first contact member when the upper portion (5) of the first contact member (4) is slidably mounted in the cage (8) of the second contact member (7). One of the transverse openings of the first and the second contact members (4, 7) is provided with at least one insulation displacement slot (20). When the screw is rotated, the transverse openings (17, 18) are forced out of alignment such that the conductors are forced into the insulation displacement slots (20).
