Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a lossless brazing flexible wiring block. Background Art

[0002] In the rail transit industry, the connection method and process between the running rails and conductors in DC traction power supply, signal systems, various equipment, and grounding systems directly affect the service life of the rails and driving safety. The main processes commonly used to handle and solve this problem in existing technologies include:

[0003] 1. Welding on rails: Welding the conductor directly to the rail waist uses exothermic welding (thermal reaction). This process is difficult to control and maintain, resulting in low reliability. Due to the high temperature, improper welding can easily lead to martensite formation, resulting in rail damage or even breakage, posing a significant risk to driving safety.

[0004] 2. Bolt connection is used. After drilling holes in the rails, expansion screws are installed to form a crimped electrical connection structure. During the application of the crimping process and products in various rail transit sites, the electrical connection capability is relatively weak compared to the welding process, especially in the DC traction return electrical connection. Due to the application environment of the electrical connection between the wire and the rail, and the fact that the crimping process is based on tightening nuts, its stability and durability are relatively weak. This process requires drilling a large number of holes in the rails, which will cause damage to the rails. The detection and control of these holes in the later operation process will consume manpower and material resources, and there are also safety risks. Utility Model Content
