Abstract
Abstract Contact head for simultaneously contacting a plurality of points in an electrical circuit, said head comprising a rigid insulating support provided with a plurality of parallel holes passing entirely through said support, a plurality of pins each adapted for sliding in one respective of said holes, and a block of elastic material attached to said support. Each pin has one of its two ends connected to a connecting lead, said end being embedded in said block, while its other end projects from said support to be applied against one of the points of the electrical circuit.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
180 words
A contact head for simultaneously contacting a plurality of points in an electrical circuit, said head comprising: - a central hole and a rigid insulating support in the form of a parallelepiped and provided with a plurality of holes passing entirely through said support in a direction parallel to the length of said parallelepiped, and opening on two opposite surfaces of said support, said holes being distributed around the periphery of said support, - a plurality of pins each adapted for sliding in one respective of said holes, each pin having one of its two ends projecting from said support at one of said opposite surfaces, and its other end projecting from said support at the other surface and soldered to a connecting lead, - and a block of elastic material disposed against said other surface of the support, said block having a protuberance positioned within said central hole of said support, said block embedding said soldered ends of the pins and exerting an elastic action on said pins when the pins have their free ends pressed against said circuit.
Claim 2
Dependent Claim
180 words
A contact head for simultaneously contacting a plurality of points in an electrical circuit, said head comprising: - a central hole and a rigid insulating support in the form of a parallelepiped and provided with a plurality of holes passing entirely through said support in a direction parallel to the length of said parallelepiped, and opening on two opposite surfaces of said support, said holes being distributed around the periphery of said support, - a plurality of pins each adapted for sliding in one respective of said holes, each pin having one of its two ends projecting from said support at one of said opposite surfaces, and its other end projecting from said support at the other surface and soldered to a connecting lead, - and a block of elastic material disposed against said other surface of the support, said block having a protuberance positioned within said central hole of said support, said block embedding said soldered ends of the pins and exerting an elastic action on said pins when the pins have their free ends pressed against said circuit.
Claim 3
Dependent Claim
59 words
In combination, a plurality of contact heads according to claim 1, and a support panel for supporting said heads, wherein each contact head further comprises at least two grooves provided on both sides of the insulating support and transversely to the direction of the pins, for receiving fixing bars secured to said support panel and engaged in said grooves.
Claim 4
Dependent Claim
17 words
A contact head as in claim 1 wherein said protuberance is force fit within said central hole.
