Active cable guards for vehicles

Abstract

The invention relates to a movable cable protection device for cars. The device comprises a first rubber plate, a second rubber plate, a rectangular sleeve ring which is hooped in the middle of the second rubber plate to be used for separating upper and lower pipelines, a pair of metal compression plates for clamping the rubber plates and a chain ring for hoisting the metal compression plates. Hoisting holes are formed in the upper ends of the first rubber plate and the second rubber plate, through holes corresponding to the hoisting holes are formed in the metal compression plates, metal sleeves penetrate the hoisting holes of the first rubber plate and the second rubber plate, bolts penetrate the metal compression plates to be fixed with the metal sleeves, and accordingly, the first rubber plate and the second rubber plate are fixed between the pair of the metal compression plates. The upper portions of the metal compression plates are fixed with the lower end of the chain ring through hinge pin components. By means of the device, the protection characteristic of the non-damage of the rubber plates to the cables, and the flexibility and the mobility of the chain ring are used for protecting the cables and binding the excessive swing of the cables, so that the limit exceeding of the cables of the friction between the cables with the framework are prevented, the electrical connection safety is improved, and the movable cable reserved length is controlled effectively.

Description

technical field [0001] The invention relates to a movable cable protection device for vehicles and belongs to the technical field of rail vehicle wiring design. Background technique [0002] The construction design of cable harness wiring on rail vehicles is an essential link. It is relatively easy to design the wiring of fixed cables in wire harness carriers such as wire troughs, but it is usually difficult to design the wiring protection of movable cables, such as in bogies. Active cables such as the vehicle body and the coupler line. The wiring cables in these areas need to be maintained in a certain space area in a swinging state with the operation of the vehicle while leaving enough cable margin. At present, fixed points are usually set at both ends of the movable cable, and there is no protective measure for the middle section of the movable cable. In practical applications, after the movable cable is installed, the swing range is too large during the operation of the...

AI Technical Summary

Problems solved by technology

The current situation is usually to set fixed points at both ends of the movable cable, and there is no protective measure for the middle section of the movable cable. In practical applications, after the movable cable is installed, the swing range is too large during the operation of the vehicle, and there is a phenomenon of exceeding the limit or friction with the frame. , bringing safety hazards to the operation of electrically connected vehicles
