Abstract
Contact device adapted to be inserted between two contact surfaces of two conductors of an electrical connection provided with at least one bolt, the device being formed by a metal foam plate to reduce electrical resistance of the connection. The surface area of the metal foam plate is at least equal to the surface area in contact with the two conductors, and is approximately 1 to 2 mm thick. The metal foam plate includes at least one circular opening intended to contain the bolt and at least one first pre-cut located between the opening and an outer edge of the contact device. The pre-cut is made by cutting the foam plate over a part of its thickness so that it can be easily broken along the pre-cut, the pre-cut allowing the bolt to be passed through it during the installation of the contact device.
