Abstract

A clamp fastener for fastening plates (4, 5) e.g. in cabinets containing electronic equipment. The plates (4,5) are clamped together between the legs of a U-shaped member (1) having converging legs and a round rod (2) disposed in the member. The fastener gives good mechanical and electrical contact along the whole of the contact length of the plates.

Claims

1. A clamp fastener for clamping two plates together comprising an elongated member of U-shaped cross-section including a base and two legs extending from said base to converge towards one another, the plates which are to be clamped together being disposed as a unit between said legs in contact with one of said legs, a rod disposed between said legs for and configured for tangentaily contacting the plates and the other of said legs, said rod being displaceable between said legs to vary the distance between the rod and the base and pressure means supported by said elongated member for displacing said rod away from said base to press said plates together by a wedging action of the rod between the convergent lens.

2. A clamp fastener as claimed in claim 1 wherein a first of said legs extends perpendicularly to said base and the second of said legs extends at an angle thereto towards said first leg.

3. A clamp fastener as claimed in claim 2 wherein said rod has a round cross-section.

4. A clamp fastener as claimed in claim 3 wherein said pressure means comprises a threaded member in said base bearing against said rod to displace said rod to cause the rod to ride on said second leg and press said plates together and against said first leg to achieve mechanical and electrical contact between said plates.
