A terminal plate assembly has a one piece inner terminal block for three pins or bolts and a separate outer terminal block for each pin or bolt. Sealing between the terminal plate and each pin is accomplished by two O-ring seals which are squeezed between the inner and outer terminal blocks. Additionally, one of the O-rings also serves to hold the assembled terminal blocks in place with respect to the terminal plate.

A terminal plate assembly comprising: (I) an inner terminal block including: (a) a generally flat elongated portion; (b) three equally spaced projections extending from one side of said flat elongated portion and each serially including a first cylindrical portion having a first diameter, a second cylindrical portion having a second diameter which is less than and first diameter with said first and second cylindrical portions together defining a flange, a frustum of a cone, an axial bore extending through said frustum, said first and second cylindrical portions and said flat elongated portion; (c) three equally spaced holes in the other side of said flat elongated portion with each of said holes being only a portion of a circle and serving as a counterbore for a corresponding one of said axial bores; (II) a plurality of outer terminal blocks each including: (a) an outer cylindrical portion having said first diameter and terminating in a flat annular portion; (b) a recess defined by a conical portion extending from said flat annular portion and being of mating configuration to said frustum and an inner cylindrical portion terminating in an annular end wall which forms an extension of a corresponding one of said axial bores in an assembled terminal plate assembly; (III) a plurality of pins each including: (a) a body portion including an unthreaded portion and a threaded portion for securing to a power source; (b) a head portion for securing to a motor lead; (c) a portion of said head portion being shaped so as to be matingly received in a corresponding one of said three equally spaced holes whereby a pin extends through said axial bore and one of said outer terminal blocks can be placed thereon so that said pin extends through said extension of said bore; (IV) first O-ring means adapted to be placed on each said second cylindrical portion and to be squeezingly engaged in a sealing engagement between said flange and said flat annular portion; (V) second O-ring means adapted to be placed on each said unthreaded portion of said pin and to be squeezingly engaged between the end of said frustum and said annular end wall; (VI) a plurality of nuts for threadably engaging said threaded portions of each of said pins to cause said inner and outer terminal blocks to come together and thereby squeezingly engage said first and second O-ring means in a sealing engagement and to cause said first O-ring to be radially extruded to thereby additionally secure said inner and outer terminal blocks in place with respect to a surrounding structure.
