Description

Technical Field

[0001] The utility model belongs to the field of civil aviation maintenance, and in particular relates to a tool for removing a metal end of an earphone blocked in an earphone jack in an airplane cabin. Background Art

[0002] Domestic civil aircraft maintenance companies encounter a variety of problems during short stops and post-flight maintenance. Among them, the problem of blockage of the headphone jack of the aircraft cabin in-flight entertainment system equipment has become the norm. This is because during the flight, passengers use headphones very frequently, and it is easy for the metal end of the headphone at the front end of the headphone plug to break and get blocked in the headphone jack, making the headphone socket unusable. If it is not handled in time, it will reduce the comfort of passengers. Long-distance passengers often complain about this problem.

[0003] In order to solve the problem of headphone jacks, the traditional maintenance method on various types of existing civil aircraft is to disassemble the headphone jack as a whole, or disassemble the TV set containing the headphone jack as a whole, and then replace it. The disassembled headphone jack or TV set needs to be sent to a special maintenance department for repair. However, the entire process from discovering the fault to receiving the parts for replacement takes too long, and the disassembly is cumbersome, and various corresponding tools are required, which wastes manpower, material and financial resources. The maintenance efficiency is low, and the frequent use of multiple tools will reduce the service life of the tools, increase the risk of tool omission, and cause flight delays.
