Abstract
Abstract A terminal block includes a printed circuit element which has conductive paths deposited on one of its surfaces, with each path extending from a terminal area surrounding an opening in the element to a centralized area. In one embodiment, the printed circuit element is a rigid board and terminals are mounted on the board and extend through each opening and project outwardly on the opposite surface of the board. The terminals are swedged at one end to physically retain them on the board and to electrically connect them to the conductive path. The rigid board is attached to an open box-like shell through which a cable carrying wire conductor extends and connects, interior to the block, to the conductive paths on the circuit board. In another embodiment, the circuit element is a flat, flexible sheet which is disposed against a support board provided with apertures aligned with the openings in the flexible sheet. The terminals extend through both the board and the sheet and may be swedged at one end to grip the support board and flexible element and to electrically connect the terminals to the conductive path. Alternately, the terminals may be soldered to the terminal area surrounding an opening of the flexible sheet. A back plate may be connected to the board to sandwich the flexible sheet therebetween.

Claim 1
Independent Claim
294 words
A terminal block comprising: a rigid support board having a plurality of spaced apertures therein; a plurality of separate printed circuit conductive paths disposed on one side of said board, each conductive path including a terminal area aligned with one of said apertures and a terminus area, the terminus areas of the conductive paths being grouped together; a terminal extending through each aperture and projecting outwardly from the opposite side of said board, each terminal including a shoulder intermediate its ends and adapted to rest against the surface of said opposite side of said board, and a hollow cylindrical mounting end adapted to be received in one of said apertures and to be deformed to physically restrain the terminal on said board against withdrawal and to physically and electrically engage said terminal with said terminal area of the respective conductive path; cooperating means on each terminal and said board locking said terminals against rotation on said board, said cooperating means comprising a mounting portion with a polygonal cross section on each terminal and a polygonal shape formed at each aperture to receive and mate with said mounting portion; a cable carrying conductors each of which is connected to a terminus area of a respective conductive path; and a box-like shell having a back wall, an upstanding rim extending about the entire periphery of said back wall, one open side and a cable opening, said board being supported on said shell at the rim to close said open side and with the surface of said one side of said board facing the interior of said shell so as to provide a space between said one side of said board and the opposing surface of said back wall, and said cable extending through said cable opening.
