Abstract

A metal spring 1 is inserted between a stacked column of connector blocks 2 and a retaining metal frame 3, as shown in the figure. The spring exerts pressure on blocks 2 in order to increase the electrostatic discharge level of a particular machine.

Connector Retaining Ground Spring

A metal spring 1 is inserted between a stacked column of connector blocks 2 and a retaining metal frame 3, as shown in the figure. The spring exerts pressure on blocks 2 in order to increase the electrostatic discharge level of a particular machine.

A problem arises because blocks 2, which are constructed of a polycarbonate material with an aluminized plating on their outer shells and side mounting slots, make a high resistance connection to ground when attached to the retaining metal frame. The solution is provided with spring 1 wedged in the uppermost opening between the top connector block and frame 3. The spring insures intimate contact between all the stacked blocks, hence a continuous ground connection. Another advantage is that the spring exerts a force which prevents accidental dislodging or unmating of all connectors, due to vibration or shock.
