Abstract
A clamping arrangement is provided that clamps a switch pole-unit (or portion thereof) to a support member. In a preferred embodiment, the clamping arrangement includes a first member that functions as a pole-unit base to support the switch pole-unit, a second member, and facilities for clamping the first and second members about the support member. The first member includes notches that each have a length that is greater than or equal to the dimension of a predetermined portion of the support member that is assembled to the first member. The clamping arrangement further includes provisions operative during or after that apply a force to secure the support member in the notches so as to prevent any movement of the support member relative to the notches of the first member; e.g., by forcing the support member into engagement with a first end of each of the notches. The force-applying provisions in one arrangement include tangs which extend from the first member and are positioned so as to extend adjacent to the second end of each of the notches. The tangs are effective to accommodate a predetermined range of dimensions for the support member and also provide self-alignment of the clamping arrangement during assembly. In a preferred arrangement, the second member also includes a notch that is dimensioned to accommodate a predetermined portion of the support member that is assembled to the second member.
