2M loopback test tool for serial port of telephone switchboard

Abstract

The invention discloses a 2M loopback test tool for a serial port of a telephone switchboard. The 2M loopback test tool comprises a male test head, a female test head and pins. The male test head andthe female test head are each provided with a shell. A male test head connecting seat is fixedly mounted in the shell of the male test head, and the pins are welded in the male test head connecting seat. A female test head connecting seat is fixedly mounted in the shell of the female test head, jacks are formed in one side of the female test head connecting seat, and a wiring groove is formed in one end of the shell. According to the invention, the male test head, the female test head and the pins are arranged. After the loopback test tool is adopted, the accuracy of a test result and the working efficiency are greatly improved, the operation process becomes very simple immediately, the possibility of wrong short circuit in the test process is reduced to zero, the operation requirements for workers are greatly reduced, meanwhile, the work which needs to be completed by cooperation of 2-3 persons in the past can be completed by independent operation of only one person, and manpower resources are saved.

Description

technical field [0001] The invention relates to the technical field of communication technology, in particular to a 2M loopback test tool for a serial port of a telephone exchange. Background technique [0002] In daily work, it is often necessary to use the loopback test to determine whether the status of the equipment is normal, but in actual work, there is no special test tool for this item, and it is generally necessary to use a digital patch panel for loopback testing. In the absence of a digital distribution frame, the test can only be carried out by short-circuiting the corresponding pin corners of the device port with bare hands. This method is neither fast nor accurate. If the operation is not done properly, it may cause damage to the device. There are security risks. Therefore urgently need to develop a kind of telephone exchange serial port 2M loopback test tool, to guarantee the safety and accuracy of loopback test, improve work efficiency.
