Patent ID: 8226428

Claim:
An electrical connection device comprising: a first high and/or medium voltage electrical contact block comprising a contact, the contact comprising a recess, the recess being cylindrical and having a cylindrical wall about a first longitudinal axis; a second high and/or medium voltage electrical contact block comprising a contact, the contact of the second block comprising a cylindrical recess, the second block movable relative to the first block; a tubular bar having a second longitudinal axis and first and second ends, the first end insertable into the recess of the contact of the first block and the second end insertable into the recess of the contact of the second block; a first insert that projects into the cylindrical recess of the first block and a second insert that projects into the cylindrical recess of the second block, wherein the wall of each recess and each insert defines an annular space, and wherein the tubular bar is insertable into the annular space; and at least one pair of conductive spring-forming elements in the first block and at least one pair of conductive spring-forming elements in the second block, wherein one of each of the pair of conductive spring-forming elements is between the insert and the tubular bar, and wherein the other of each of the pair of conductive spring-forming elements is between the tubular bar and the cylindrical wall of the recess, wherein an inclination of an angle a is possible between the first longitudinal axis and the second longitudinal axis, wherein the tubular bar remains in electrical contact with the contact of the first and second block during the inclination by the at least one pair of conductive spring-forming elements when the electrical connection device is being assembled and disassembled, wherein the spring-forming elements are annular, and further comprising at least three mechanical connection supports distributed around the circumference of the cylindrical recess.
