Description

Technical Field

[0001] This utility model relates to the field of testing technology for navigation light cables, specifically a quick plug for testing the insulation resistance of navigation light cables. Background Technology

[0002] The insulation resistance of navigation light cables is a crucial operational indicator. According to Table A-8 of the "Operation and Maintenance Regulations for Navigation Light Systems in Civil Airports," the insulation resistance of cable circuits of different lengths should meet the requirements in the table below. The Civil Aviation Administration of China's Safety Committee Office has issued the "Standards for Judging Major Safety Hazards in Civil Aviation (Trial Implementation)," which stipulates that runway lights, approach lights, and PAPI lights whose insulation resistance does not meet the standard requirements will be judged as major safety hazards. If a navigation light circuit cable experiences a complete grounding fault at two or more points, the navigation lights between the two grounding points will dim or completely go out, significantly impacting operational support and potentially leading to the closure of the airport due to the inability to guarantee the normal operation of aircraft.

[0003] When the insulation resistance of the navigation light cable decreases, a megohmmeter (megohmmeter) needs to be used to check the cable connectors connected to the cable in the isolation transformer box of the field circuit. Each isolation transformer box has two cable connectors, one with a socket and the other with a pin. During testing, one person needs to operate the megohmmeter and another person needs to assist in connecting the circuit. Each point requires two people to complete the testing operation, which is labor-intensive and inefficient. In addition, the person assisting in connecting the circuit is prone to touching the output wire of the megohmmeter and getting an electric shock. Although the output current of the megohmmeter is small, there will still be an electric shock and pain. When people touch the output wire, it will cause inaccurate test data.

[0004] Based on this, this utility model designs a quick plug for detecting the insulation resistance of navigation light cables to solve the problem. Utility Model Content

[0005] The purpose of this invention is to provide a quick plug for testing the insulation resistance of navigation light cables, so as to solve the problems in the background technology that require two people to operate and that workers are prone to electric shock.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick plug for detecting the insulation resistance of navigation light cables, comprising a cable connection post and a connection mechanism. The connection mechanism is located on the right side of the cable connection post. The connection mechanism includes a cable connection pin installed on the right side of the cable connection post. A wire is provided above the cable connection post. The right end of the wire is electrically connected to the outer surface of the cable connection post.

The inner wall of the heat shrink tubing is fixedly connected to the outer surface of the wire, the outer surface of the cable connection post, and the outer surface of the cable connection pin. A clamp is fixedly installed on the outer surface of the heat shrink tubing. A insertion hole is provided on the left side of the cable connection post.
