Through-wall terminal of rail transit converter device

Abstract

The invention relates to a through-wall terminal, particularly to a through-wall terminal of a rail transit converter device, and aims to solve the problem of poor contact of a high-voltage electricalconnection part caused by axial movement of a terminal body once a fastening bolt of an existing through-wall terminal is loosened. The through-wall terminal of the rail transit converter device comprises a terminal body and a mounting plate, wherein the terminal body is composed of a terminal seat and a connecting copper bar, the terminal seat comprises a cylinder, a connecting flange is arranged around the middle of the cylinder, a skewed shaft hole is formed in the cylinder, the connecting copper bar is inserted into the skewed shaft hole, the two ends of the connecting copper bar extend out of the cylinder, a center hole matched with the cylinder is formed in the center of the mounting plate, buckles are uniformly distributed around the cylinder, the surfaces, facing the connecting flange, of the buckles are planes, the distance between the plane, facing the connecting flange, of each buckle and the connecting flange is equal to the thickness of the mounting plate, clamping grooves corresponding to the buckles in position and matched with the buckles in shape are evenly distributed around the center hole of the mounting plate, and the sides, facing the circle center of the center hole, of the clamping grooves are open.

Description

technical field [0001] The invention relates to a wall-through terminal, in particular to a wall-through terminal for a rail transit converter. Background technique [0002] The through-wall terminal is a terminal that realizes the electrical connection inside and outside the converter device. This part is widely used in the converter device with sealing requirements. [0003] The existing through-the-wall terminal includes a terminal body and a mounting plate; the terminal body is composed of a terminal base and a connecting copper bar (for connecting the electrical lines outside and inside the converter cabinet), the terminal base includes a cylinder, and the center of the cylinder is set There are connecting flanges, bolt through holes are evenly distributed on the connecting flanges, there are partial shaft holes on the cylinder, the connecting copper bar is inserted into the partial shaft holes, and the two ends protrude from the cylinder, and there are holes on the pro...

AI Technical Summary

Problems solved by technology

[0006] The invention solves the problem that once the fastening bolts of the existing through-the-wall terminals are loosened, the terminal body will move axially, thereby resulting in poor contact of the high-voltage electrical connection parts, and provides an improved through-the-wall terminal of the rail transit converter device
