Abstract
Description
Technical Field
[0001] This application relates to the technical field of test equipment, and particularly relates to a connector fretting abrasion testing machine. Background Art
[0002] After the connector is installed and used on a vehicle, the vibration of the vehicle will cause the wire harness to be pulled, so that the mating PIN pins of the connector will have a small displacement of about 50 microns. Long-term small displacements will cause fretting abrasion on the surface of the PIN pins. Fretting abrasion will cause an increase in the resistance of the connector, and further cause problems such as overheating and overcurrent of the connector. Therefore, a connector fretting abrasion testing machine is needed to verify in advance whether the connector will undergo fretting abrasion.
[0003] The existing connector fretting abrasion testing machines mainly adopt a driving method of a rotary motor + lead screw nut mechanism, and it is difficult to guarantee the accuracy, which affects the test results. Summary of the Utility Model
[0004] In view of this, embodiments of this application provide a connector fretting abrasion testing machine to solve the problem of poor accuracy of the driving mechanism of the existing connector fretting abrasion testing machine.
[0005] An embodiment of this application provides a connector fretting abrasion testing machine, including a first mounting seat, a second mounting seat and a linear motor. The first mounting seat and the second mounting seat are arranged at intervals along a first direction. One of the first mounting seat and the second mounting seat is used to mount the male end of the connector, and the other of the first mounting seat and the second mounting seat is used to mount the female end of the connector; at least one of the first mounting seat and the second mounting seat is connected to the corresponding linear motor to realize the mutual approach or separation of the first mounting seat and the second mounting seat in the first direction.
[0006] The beneficial effect of the connector fretting abrasion testing machine provided by the embodiment of this application is that: by connecting at least one of the first mounting seat and the second mounting seat to the corresponding linear motor, during the test, the linear motor is used to drive the first mounting seat and the second mounting seat to approach or separate from each other in the first direction, so that after the male end and the female end of the connector are mated, a small displacement is generated in the male end within the female end to verify whether the connector will undergo fretting abrasion. Compared with the driving method of a rotary motor + lead screw nut mechanism, the linear motor does not require a lead screw nut mechanism to transmit power, and the driving accuracy is relatively high, which can improve the accuracy of the test results.
[0007] In some embodiments, the connector fretting abrasion testing machine further includes a base, and the first mounting seat, the second mounting seat and the linear motor are arranged on the base.

[0013] In some embodiments, the adjusting device further includes a first adjusting structure for adjusting the second mounting seat in the first direction.
[0014] Adjusting the position of the second mounting seat in the first direction through the first adjusting structure is beneficial to the mating insertion of the male end and the female end of the connector, and at the same time can reduce the moving distance of the linear motor.
[0015] In some embodiments, the first mounting seat includes a first seat body and a first pressing member detachably connected to the first seat body, and at least one first fixing hole is formed between the first seat body and the first pressing member;
[0016] And / or, the second mounting seat includes a second seat body and a second pressing member detachably connected to the second seat body, and at least one second fixing hole is formed between the second seat body and the second pressing member.
[0017] Pressing one of the male end and the female end in the first fixing hole through the cooperation of the first pressing member and the first seat body, and pressing the other of the male end and the female end in the second fixing hole through the cooperation of the second pressing member and the second seat body are beneficial to the disassembly and assembly of the male end and the female end on the first mounting seat and the second mounting seat.
[0018] In some embodiments, the linear motor is a voice coil motor.
[0019] When the voice coil motor is working, it not only has high driving accuracy but also fast response, which can further improve the accuracy of test results.

[0021] By using the resistance measuring instrument to record the change in resistance during the test in real time, the severity of the fretting abrasion of the connector is judged.
[0022] In some embodiments, the connector fretting abrasion testing machine further includes an electron microscope for observing the surface change of the connector during the test.
[0023] By adopting the above technical solution, the electron microscope can observe the degree of oxidation of the connector during the fretting abrasion process; at the same time, there is a scale on the electron microscope, and it can be observed whether the tiny displacement generated by the male end in the female end is consistent with the designed displacement value, so as to ensure the accuracy of the test results.
