Jumper wire applied to electric locomotive vehicle

Abstract

The invention discloses a jumper wire applied to an electric locomotive vehicle. The jumper wire comprises a connector plug (4), connector adapters (5), a tail clamp (6) and a cable (7), wherein the cable (7) penetrates through the tail clamp (6) and the connector adapters (5) sequentially, and is connected with the connector plug (4); the connector adapters (5) are bent connector adapters. According to the jumper wire applied to the electric locomotive vehicle provided by the invention, the connector adapters are set as the bent connector adapters, and the cable penetrates through the tail clamp and the connector adapters, and is connected with the connector plug. The cable is guided by the bent connector adapters, the bending angle of the cable between the two connector adapters is convenient to adjust, the convenient arrangement is also realized when the spacing between carriages of the electric locomotive is smaller, the convenience in arrangement of the jumper wire applied to the electric locomotive vehicle is improved, and the reliability of the jumper wire in a motion state is improved, and the service life of the jumper wire is prolonged.

Description

technical field [0001] The invention relates to the technical field of electric locomotive equipment, in particular to a jumper wire applied to electric locomotive vehicles. Background technique [0002] Because electric locomotives are driven by high-power DC and AC motors, they are integrated with complex power transmission and signal transmission systems. Most of the power transmission and signal transmission lines are bridged at the undercarriage end of the vehicle through jumper wires. [0003] The jumper wires are usually exposed at the bottom of the vehicle's underframe. The jumper wires need to adapt to the irregular movement between the compartments and the exposed natural environment, and their electrical, mechanical and environmental performance requirements are extremely high. The signal and power cables on common jumper cables are single-core multi-strand wires, and the outside is wrapped with nylon corrugated hose. Both ends of the jumper are equipped with ada...

AI Technical Summary

Problems solved by technology

The connection between the adapter and the nylon hose is often moved, and it is easy to loosen and enter water vapor, and the nylon hose will still age, break and enter water vapor, affecting electrical performance

[0004] In addition, the tail attachment of the connector is a straight head. When the jumper wire is short, that is, the distance between the control boxes on two adjacent cars is small, and when the jumper cable integrates a lot of signal wires or high-current power wires, the wires When the diameter of the cable sheath is thick, the bending radius of the jumper wire will be small, and the number of bends will be large, which is not convenient for installing the jumper wire between the two carriages
