Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of auxiliary assembly equipment for high-voltage contact devices, and specifically relates to a separate auxiliary assembly fixture for high-voltage contact devices. Background Technology
[0002] The high-voltage contact device is part of the aviation ignition system. A conductive rod is installed inside its insulating sleeve. One end of the conductive rod's lead wire connects to the inside of the ignition device, while the other end is tightly fitted to the center electrode of the output cable. Power is supplied to the ignition device via the high-voltage contact device and then transmitted to the output cable. The output cable then transmits the power to the spark plug, creating a spark and achieving ignition. In the high-voltage contact device assembly, the proper installation and secure fixing of the conductive rod is crucial for the normal operation of the product.
[0003] In existing technologies, conductive rods are installed by applying tension to the lead wires. However, the installed conductive rods are susceptible to displacement due to pressure from the insulating sleeve. Since the adhesive used to fix the conductive rods requires at least 24 hours to cure, tension must be maintained on the lead wires throughout the curing process to ensure the conductive rods are fixed in the specified position. However, the lead wires are easily damaged during curing, and the dimensions of the conductive rods are difficult to guarantee, resulting in poor consistency and wasting time and effort.
