The outer cover of the support frame is provided with a housing, and the housing includes at least two An electrical connector installation box fixed on the bridging beam and a protective tile arranged between adjacent electrical connector installation boxes, an electrical connector is fixedly arranged on at least one vertical wall of the electrical connector installation box.

One of the electrical connector installation box and the protective tile is provided with a slot and the other is provided with a key, and the electrical connector installation box is snap-fitted with the protective tile.

An installation hole for installing an electrical connector is provided on the side plate of the electrical connector installation box, and the electrical connector is fixedly assembled in the installation hole.

The top of the electrical connector installation box is provided with a cover plate.

The protective tile is in the shape of a circular arc, and keys are provided on both side edges parallel to the axis of the slip ring sleeve, and corresponding slots are provided on the bottom of the electrical connector installation box. The above-mentioned electrical connector installation box is connected with the above-mentioned protection tile.

The protective tile is in the shape of a circular arc, and there are slots on both side edges parallel to the axis of the slip ring bushing. The bottom of the electrical connector installation box is provided with a corresponding key. The above-mentioned electrical connector installation box is connected with the above-mentioned protection tile.

Because the utility model changes the traditional integrated electric rotary connector shell into a split structure through the combination of the electric connector installation box and the protective tile, it is convenient for the staff to overhaul the electric rotary connector; further, the electrical connection The connector installation box is connected with the protection tile, and the protection tile can be easily disassembled only by loosening the electrical connector installation box. The electrical connector installation box is provided with an electrical connector installation hole, and the wire of the electrical rotary connector can be connected with the electrical connector plug or socket, which facilitates the wiring of the rotary connector at the point; in the electrical connector The top of the installation box is provided with a cover plate, so that the brushes, electric slip rings and other components can be completely covered inside the housing, which is conducive to its protection; A card key or a card slot is provided on the protective tile, and a corresponding card slot or card key is provided on the electrical connector installation box.
