Power Tool, Trailer Connecting Wire Harness
Well, the user’s question is about power tools and trailer connection harnesses. I need to see what relevant information is in the search results first. First, the search results mention related patents and products for trailer connection harnesses, such as Weidiankang’s patent for quick-disassembly and assembly harness connectors, and the design of US-standard 7-pin trailer sockets and harnesses. Zusätzlich, YAXUN’s harness production equipment patent 1 and automotive harness terminal crimping process 6 may involve harness manufacturing and quality control.
