ABSTRACT:
The terminal block assembly of this invention provides a finger safe method of distributing power while at the same time enabling the installer to make uniform and correct connections to a multiplicity of taps or ports. Each connection includes an abutment or seat physically to engage the end of the conductor and in addition the construction of the block and its insulating case provides the installer with visual access to the tip of the conductor in its proper seated position before the conductor is secured to the block with clamp screws. In order to provide such visual access the walls partially blocking the seating end of each conductor socket are scalloped or provided with an inverted conical section which enables the tip of each conductor to be seen from the top of the block. To facilitate this visual access the entire top of the insulating case is made from a transparent material. In one embodiment the top is provided with interior projections serving both to gauge and limit retraction of some of the clamp screws to prevent loose screws in the case. In another embodiment the screws, even though fully retracted or disengaged from the blcok, are held in axial alignment with their respective sockets and can't become loose in the case.
