[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0032] Refer to Figures 1-7 As shown, a test tool for a PLC optical splitter includes:

[0033] A mounting base plate 1, with mounting waist holes 101 penetrating through the four corners of the mounting base plate 1. A plurality of vertically upward extending guide posts 102 are fixedly connected to the rear side of the upper end of the mounting base plate 1, and an upper mounting plate 103 is fixedly installed at the upper ends of the guide posts 102;

[0034] A port alignment component, which includes a substrate 2 fixedly installed on the upper end of the mounting base plate 1. A lower alignment substrate 3 is slidably installed in the middle of the upper end of the substrate 2. Vertically upward extending support pillars 4 are fixedly connected to both sides of the upper end of the substrate 2, and an upper alignment substrate 401 is fixedly installed at the upper ends of the support pillars 4. A plurality of alignment seats 5 are installed at the upper ends of the lower alignment substrate 3 and the upper alignment substrate 401. The front end of the alignment seat 5 is used to connect the optical splitter output port 6. An input alignment seat 7 is fixedly connected to one side of the upper end of the substrate 2. The front end of the input alignment seat 7 is used to connect the optical splitter input port 8, and the rear end of the input alignment seat 7 is used to connect the optical emission port 9;

[0035] A plug-in component, which includes a plug-in mounting plate 10 slidably connected to the guide posts 102, and a plurality of detection components 11 are installed at the upper end of the plug-in mounting plate 10;

[0036] Adopt a structure of installing two sets of alignment seats on a double-layer alignment substrate, and at the same time adopt a lifting and sliding method to adjust the movement of the detection component 11. When in use, first insert the optical splitter output port 8 on a set of alignment seats 5, and then test the optical splitter output port 8 of this group through the detection component 11. During the test process, synchronously insert the optical splitter output port 8 on another set of alignment seats 5 to realize the synchronous progress of the insertion and test steps of the optical splitter output port 8 and the alignment seats 5. Repeat this cycle until the tests of all optical splitter output ports 8 are completed.

[0037] A wire bundling clip is installed on one side of the substrate 2. The wire bundling clip includes an OK wire clip 202 and an NG wire clip 201. The OK wire clip 202 and the NG wire clip 201 are arranged alternately. The OK wire clip 202 is used to accommodate and position the optical splitter input port 8 with a passing test, and the NG wire clip 201 is used to accommodate and position the optical splitter input port 8 with a failing test. This setting effectively ensures the classification of the optical splitter input ports 8 and prevents the confusion of the optical splitter input ports 8 from occurring during the multi-channel optical splitter test.

[0038] A lifting drive screw 12 is rotatably installed at the lower end of the upper mounting plate 103. The lifting drive screw 12 is threadedly connected to the plug-in mounting plate 10. A drive motor 13 is fixedly installed at the upper end of the upper mounting plate 103. The output end of the drive motor 13 penetrates through the upper mounting plate 103 and is fixedly connected to the lifting drive screw 12. When the drive motor 13 is started, it drives the lifting drive screw 12 to rotate.

[0039] A pull-out groove 301 is formed through the front end of the substrate 2. Sliding grooves 203 are symmetrically formed inside the upper end of the substrate 2. Slide bars 302 are fixedly connected to both sides of the lower alignment substrate 3. The slide bars 302 are slidably connected inside the sliding grooves 203. The lower alignment substrate 3 is installed in a sliding manner. When the lower alignment substrate 3 is pulled out, the optical splitter input port 8 is inserted, and when the lower alignment substrate 3 is pushed in, the optical splitter input port 8 is tested.

[0040] A number of spring-up positioning blocks 204 are arranged at the upper end of the substrate 2. Positioning grooves 303 are formed at the corresponding positions on the lower end of the lower alignment substrate 3. The spring-up positioning blocks 204 are adapted to the positioning grooves 303. Two rows of positioning grooves 303 are formed, and three rows of spring-up positioning blocks 204 are arranged. When the lower alignment substrate 3 is pulled out, the first row and the second row of spring-up positioning blocks 204 are clamped in the positioning grooves 303 to realize the positioning of the lower alignment substrate 3. At this time, the optical splitter input port 8 can be inserted into the alignment seat 5 on the lower alignment substrate 3. When the lower alignment substrate 3 is pushed in, the second row and the third row of spring-up positioning blocks 204 are clamped in the positioning grooves 303 to realize the positioning of the lower alignment substrate 3. At this time, the optical splitter input port 8 inserted into the alignment seat 5 on the lower alignment substrate 3 can be tested.

[0041] The four corners of the plug-in mounting plate 10 are provided with through guiding holes 1001. The guiding columns 102 are slidably connected to the inside of the guiding holes 1001. A threaded hole 1002 is provided through the middle of one side of the plug-in mounting plate 10. The lifting driving screw 12 is threadedly connected to the inside of the threaded hole 1002. The rotation of the lifting driving screw 12 drives the plug-in mounting plate 10 to lift along the guiding hole 1001 through the thread. The upper end of the guiding column 102 is provided with a lifting limiter 104. The lifting limiter 104 limits the upward stroke of the plug-in mounting plate 10, ensuring that when the plug-in mounting plate 10 rises to the maximum height, the detection assembly 11 corresponds to the position of a group of alignment seats installed on the upper alignment substrate 401.

[0042] The detection assembly 11 includes a plug-in cylinder 1102. The plug-in cylinder 1102 is fixedly installed on the upper end of the plug-in mounting plate 10 through a cylinder seat 1101. The output end of the plug-in cylinder 1102 is fixedly connected to a connecting plate 1103. The front end of the connecting plate 1103 is fixedly connected to a detection head mounting member 1104. A detection plug 14 is installed on the detection head mounting member 1104. The plug-in cylinder 1102 is used to push the detection plug 14 to perform telescopic movement, thereby realizing the docking and pulling out of the detection plug 14 and the alignment seat 5. Specifically, when the plug-in cylinder 1102 pushes the detection plug 14 forward, the docking of the detection plug 14 and the alignment seat 5 can be realized. When the plug-in cylinder 1102 pushes the detection plug 14 backward, the pulling out of the detection plug 14 and the alignment seat 5 can be realized.

[0043] A detection head mounting clip 1107 is fixedly installed on the front side of the detection head mounting member 1104 through bolts. The detection head mounting member 1104 and the detection head mounting clip 1107 cooperate to fix the detection plug 14. The detection plug 14 is fixedly installed in the way of the detection head mounting clip 1107. When the detection plug 14 fails, only the detection head mounting clip 1107 needs to be removed to realize the replacement and maintenance of the detection plug 14.

[0044] A plug-in slide rail 1105 is fixedly installed at the corresponding position of the upper end of the plug-in mounting plate 10 and the detection head mounting member 1104. A plug-in slider 1106 is slidably installed on the plug-in slide rail 1105. The plug-in slider 1106 is fixedly installed at the middle of the lower end of the detection head mounting member 1104. The slide rail and slider structure effectively ensures the movement stability when the plug-in cylinder 1102 pushes the detection head mounting member 1104 to slide, and thus the precise plugging between the detection plug 14 and the alignment seat 5 can be realized, ensuring the stability of the detection process of this solution.

[0045] The usage process of the present invention is as follows: First, connect the input port 8 and the optical emission port 9 of the optical splitter to both ends of the input alignment seat 7 respectively. Then, pull out the lower alignment substrate 3, insert the output port 8 of the optical splitter into the alignment seat 5 on the lower alignment substrate 3. After the insertion is completed, push the lower alignment substrate 3 back. Then, the insertion cylinder 1102 pushes the detection plug 14 forward to achieve the docking of the detection plug 14 with the alignment seat 5, and the external detection device tests the output port 8 of the optical splitter. At the same time, insert the output port 8 of the optical splitter into the alignment seat 5 on the upper alignment substrate 401. After the test is completed, the insertion cylinder 1102 pushes the detection plug 14 backward to achieve the extraction of the detection plug 14 from the alignment seat 5. Then, when the drive motor 13 starts, it drives the lifting drive screw 12 to rotate, thereby driving the drive insertion mounting plate 10 to lift along the guide hole 1001 to the upper test position. Then, repeat the test process. At the same time, pull out the lower alignment substrate 3 to insert and extract the output port 8 of the optical splitter, and place the tested output port 8 of the optical splitter on the OK clamp 202 or the NG clamp 201 according to the test results. Repeat this cycle until the tests of all output ports 8 of the optical splitter are completed.

[0046] In summary, the advantages of the present invention are as follows: It adopts a structure of double-layer alignment substrates to install two groups of alignment seats, and at the same time adopts a lifting and sliding method to move and adjust the detection component, realizing the synchronous progress of the insertion and test steps of the output port of the optical splitter and the alignment seat, effectively shortening the test time of the PLC optical splitter and greatly improving the test efficiency of the PLC optical splitter.
