Abstract: A clamp assembly for servicing electronic circuits is disclosed. The clamp assembly has two or more clamps (1, 2). The clamps are mounted on a rod (3) extending through each clamp. The space between the clamps may be stably increased or reduced by simply sliding one or both of the clamps along the rod to engage the ball bearing in each clamp on a dimple in the rod. A bushing is used as a pivot for each clamp. The rod passes through the bushing and the bushing holds the flanges of the clamp together on the rod. A spring (6) is fitted to the clamp arms (5A) by a locating dowel on each arm of the clamp. Squeezing the ends (5A) of the lever arms together allows the clamp to open. Each of the clamps is preferably lined with an insulating and heat resistant ceramic or plastic pad. These pads have V-shaped grooves formed in them to assist in the holding of small electrical components or electrical leads. This allows wiring etc.
