Electrical Grounding Bracket 
.
The problem: 
To provide a device which serves as a common 
grounding point for the shielded wires of a multipin 
electrical connector and permits addition or removal 
of ground leads without disturbing the other grounded 
wires. 
The solution: 
A specially shaped bracket which fits around the 
connector and supports a grounding bar to which 
shield ground wires can be fastened. 
How it's done: 
The grounding bracket shown in the shaded portion 
of the diagram conforms to the exterior configuration 
of a typical multiple-pin connector. In essence, it 
is simply a rigidly supported, rounded strip of metal 
onto which may be soldered the shield-ground leads 
of the shielded wires leading to the connector pins.
The electrical grounding bracket simplifies solder 
operations and the dressing of shield terminations. 
Because each shield-ground lead can be soldered in-
dependently to the bracket, it is a simple matter to 
alter the wiring configuration of the connector or to 
remove or add shielded wires. The bracket also per-
mits addition or deletion of a ground circuit without 
disturbing the remaining ground wires, and the 
grounding bracket may itself be unfastened from the 
connector for electrical tests. Although the bracket 
provides a minimum of two parallel DC ground paths 
through the connector shell, by appropriate insula-
tion of one mounting screw, only one path can be 
obtained; multiple paths or selective grounding points 
can be obtained by wires attached to the bracket.
