The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application.

[0029] Referring to Figure 1 and Figure 2 The utility model discloses a detection appearance with plug wire detection function.

[0030] A detection appearance with plug wire detection function, including casing 1, plug wire interface 2, pcb mainboard 4 and switch part 3. Plug wire interface 2 and pcb mainboard 4 electrically conductive, and switch part 3 is located in the plug wire interface inside and is electrically connected with pcb mainboard 4, and switch part 3 controls pcb mainboard 4 to start, and switch part 3 is connected and starts detection appearance. Switch part 3 is disconnected when the cable to be tested is not inserted in plug wire interface 2, and closes the detection appearance.

[0031] Switch part 3 is used to contact with the cable to be tested inserted in plug wire interface 2, to conduct and start detection appearance, and is disconnected and closes detection appearance after the cable is pulled out plug wire interface 2.

[0032] After the cable is inserted in plug wire interface 2, cable and switch part 3 contact, so that switch part 3 electrically conductive, pcb mainboard 4 is started, and detection appearance is started, and cable test starts.

[0033] After the cable is pulled out plug wire interface 2, switch part 3 is released, and switch part electrically breaks circuit, and pcb mainboard 4 is closed, and detection appearance is closed, and cable test ends.

[0034] Based on the above technical scheme, add switch part 3 in detection appearance and electrically connected with pcb mainboard 4 and control pcb mainboard 4 to start, after the cable is inserted in plug wire interface 2, cable and switch part 3 contact, and electrically conductive switch part 3, and start pcb mainboard 4 simultaneously, directly enter test step, do not need to separately carry out switch closing operation, reduce the operation step in test process, improve test efficiency. Similarly, after cable test ends, directly pull out cable interface, do not carry out switch disconnecting operation, reduce the operation step in test process, improve test efficiency.

[0035] Based on the above technical scheme, the switch part is electrically connected with the pcb mainboard 4 and controls the start switch part of the pcb mainboard. After the cable is inserted into the plug-in interface, the cable and the switch part are in contact, and the switch part is electrically conducted, and the pcb mainboard is started synchronously, and directly enters the test step. Thus, the tester is started only when the cable is inserted, and after the cable is pulled out, the tester is completely in the power-off state. Compared with the test process of the tester in the prior art, the standby process of the tester is shortened or omitted, the standby current is reduced, and the electric energy is saved.

[0036] In addition, in the above scheme, the switch part 3 is always in the disconnected state before the cable is inserted into the plug-in interface 2, which avoids the pcb mainboard 4 from being conducted when the cable is not connected, disturbs the test program and test process, and affects the accuracy of the test result.

[0037] In the above scheme, after the test cable is inserted into the plug-in interface 2, the switch part 3 is synchronously conducted, and the pcb mainboard 4 is synchronously started, which not only simplifies the test operation process, but also avoids the operation error problem in the test process. In addition, by setting the switch part 3, the pcb mainboard 4 is conducted and started at the same time when the cable is inserted into the plug-in interface 2, which reduces the setting of the switch in the prior art, simplifies the structure of the tester as a whole, and reduces the requirements for the test angle and position during the use of the tester, so that the tester no longer needs to be placed and angled due to the exposure of the switch position.

[0038] In the above technical scheme, the switch part is located inside the plug-in interface, which realizes the hiding of the switch part, avoids setting the control switch and other structures on the surface of the shell, simplifies the shell structure of the tester, reduces the number of parts on the surface of the shell, and makes the appearance of the test more beautiful.

In the embodiment, the synchronous closing and opening of the switch part is automatically realized through the cable insertion and cable pulling out, that is, the electrical conduction and electrical disconnection of the switch part 3 are realized synchronously, the manual closing or opening operation process of the control switch is saved, the operation steps in the test process are reduced, the test process is simplified, the test efficiency is improved, and the test accuracy is ensured. In addition, the synchronous closing and opening of the switch part is automatically realized through the cable insertion and cable pulling out, that is, the electrical conduction and electrical disconnection of the switch part 3 are realized synchronously, and the standby process of the tester is shortened or saved, the standby current is reduced, and the electric energy is saved.
