Patent ID: 6991478

Claim:
An electrical connection device, designed to make a metallisation point on a support, said support having two electrically conducting support faces substantially opposite each other, and a support hole passing through said support, that opens up on each of said support faces, said electrical connection device comprising: two electrically conducting contact parts, each with a peripheral part and a central part, and each having first and second substantially opposite faces, each first face having a peripheral face corresponding to the peripheral part and a central face corresponding to the central part, the peripheral face and the central face being delimited by a shoulder, and said central face being substantially plane so as to come substantially into plane contact with one of said support faces, when in service, two seals designed to be compressed between the peripheral face on one of the contact parts and on one of the two support faces respectively, when in service, and means of fastening the device on the support, capable of maintaining electrical contact between said conducting support faces and said contact parts, wherein the means of fastening comprise: a hole in each of the two contact parts, passing through it along an axial direction substantially centred with respect to its central part and its peripheral part, and through fastening means with an axial direction, designed to pass firstly through the hole in one of the contact parts, then through the support hole, then through the hole in the other contact part, when in service, wherein said through fastening means comprise two clamping parts, each clamping part comprising a cylindrical part terminating at one end by an end collar and provided with locking means at the other end, said locking means being capable of cooperating to lock said two clamping parts together, and each end collar being designed to bear in contact with the second face of one of the two contact parts, when in service, and wherein the cylindrical parts of said clamping parts are hollow and said through fastening means also comprise a screw/nut assembly, the screw having a screw stem designed to pass through one and then the other clamping parts when in service, and the screw having a screw head designed to bear in contact with the end collar of one of the clamping parts when in service, and the nut being designed to bear in contact with the end collar of the other clamping part when in service.
