During the test process, the wire may be dragged inadvertently, and the connector may fall off from the test head of the optical power tester, thereby damaging the test head of the optical power tester. When not in use, the test head of the optical power tester lacks protective equipment, which makes it easy for dust and moisture to enter, causing damage to the inside and affecting the use. Therefore, there is a large room for improvement.

When the optical power tester body 1 is not working, the threaded cover 3 is threadedly sleeved on the outside of the test head body 101 to prevent the test head body 101 from being damaged by bumps or moisture.

[0022] Reference Figure 4 A fixing plate 4 is fixedly connected to one side of the optical power tester body 1, and a bearing plate 402 is movably connected to the top of the fixing plate 4 through a plurality of springs 401. The rubber block 1 403 and the rubber block 2 404 are both fixedly connected to the top of the bearing plate 402. A card slot adapted to the wire 201 is provided on the top of the rubber block 1 403, and the card slot is slightly smaller than the wire 201. A card slot adapted to the plug 2 is provided on the top of the rubber block 2 404, and the card slot is slightly smaller than the plug 2. When the test head body 101 is connected to the plug 2, the bearing plate 402 can be pressed down to squeeze the spring 401, thereby making the rubber block 1 403 The first rubber block 403 and the second rubber block 404 are moved down to facilitate the threaded connection between the plug 2 and the test head body 101. After the plug 2 and the test head body 101 are connected, the carrier plate 402 can be released. At this time, the rubber block 1 403 and the second rubber block 404 are moved up, and the grooves on the top of the rubber block 1 403 and the second rubber block 404 are respectively engaged with the wire 201 and the plug 2, which play a role of squeezing and fixing the rubber block 1 403 and the second rubber block 404.

[0025] The implementation principle of the protection structure of the test head of an optical power tester in the embodiment of the present application is as follows: by setting a threaded cover 3, a rubber block 1 403 and a rubber block 2 404, the connector can be inserted into the socket of the optical terminal device to be tested, and the threaded cover 3 is screwed out, and the threaded cover 3 is hung on one side of the optical power tester body 1 through the connecting iron chain 302. When the test head body 101 is connected to the plug 2, the bearing plate 402 can be pressed down to squeeze the spring 401, thereby moving the rubber block 1 403 and the rubber block 2 404 downward, so that the plug 2 is threadedly connected to the test head body 101. After the plug 2 and the test head body 101 are connected, they can be released. The load-bearing plate 402, at this time, the rubber block 1 403 and the rubber block 2 404 move up, and the card slots on the top of the rubber block 1 403 and the rubber block 2 404 are respectively engaged with the wire 201 and the plug 2, which play a role of squeezing and fixing the rubber block 1 403 and the rubber block 2 404.
