ABSTRACT:
A wiring connection terminal block having a housing for accommodating a movable block and a compression spring, is arranged within an insulator made of fire-proof synthethic polyester. Two opposite sides of the housing each has a wire hole with oblique surface, forming a sharp wedge at the top rim of each hole. The moveable block has a wire hole with oblique surfaces forming concavities into opposite surfaces of the moveable block. The oblique surfaces are positioned at the bottom rims of the wire holes on the surface of the moveable block and extend into the moveable block. A wire is inserted into the wiring holes by compressing the compressing spring to bring the wiring holes of the moveable block into alignment with the wiring holes of the housing. When the compressing spring is released an inserted wire is pushed upward and bent into the concavities on either side of the moveable block by the force of the compressing spring. Electrical connection between the housing and the inserted wire in the wire holes is created by the sharp wedges on the housing which pierce the wire cover when the wire is forced against the points.
