[0018] Please refer to Figures 1-3 , an embodiment provided by the present utility model: a test tool for a PLC optical splitter, including a base 1, a support vertical plate 2 vertically fixed at the top of the base 1, a plurality of flange plates 3 installed on the support vertical plate 2, and detection plugs 4 respectively inserted at one end of the flange plates 3. A plurality of mounting holes 101 are provided at the edge of the base 1, and the base 1 can be fixed at the working location through bolts to improve stability.

[0019] On the other end of the flange 3, a feeding mechanism 6 is provided for simultaneously inserting a plurality of test line connectors 5 into the inside of the detection plug 4 for testing. Specifically, the feeding mechanism 6 includes two vertically arranged connecting rods 601, a first placing seat 602 and a second placing seat 603 respectively fixed at the upper and lower ends of the connecting rod 601, and a first pressing plate 604 and a second pressing plate 605 respectively arranged above the first placing seat 602 and the second placing seat 603. The two sides of the first pressing plate 604 and the second pressing plate 605 are respectively slidably connected to the two connecting rods 601. The second placing seat 603 is located above the first placing seat 602, and baffles 606 for limiting the second pressing plate 605 are fixed at the tops of the connecting rods 601. A plurality of positioning openings 6021 matching the test line connectors 5 are equally spaced on the first placing seat 602 and the second placing seat 603. The distance between adjacent two positioning openings 6021 is equal to the distance between adjacent two flanges 3. The first placing seat 602 and the second placing seat 603 have the same structure, both being L-shaped plate structures, including a bottom plate and a vertical plate vertically fixed on one side of the top of the bottom plate. The positioning openings 6021 are arranged on the vertical plate. When the test line connector 5 is placed on the bottom plate, the wires of the test line connector 5 can pass through the positioning openings 6021. Further, the height of the vertical plate is less than the height of the test line connector 5. When pinching the first placing seat 602 and the first pressing plate 604 or the second placing seat 603 and the second pressing plate 605, all the test line connectors 5 can be clamped simultaneously, which is convenient for the insertion and extraction of the test line connectors 5. Further, elastic rubber pads can also be arranged at the bottom ends of the first pressing plate 604 and the second pressing plate 605 to improve the clamping firmness.

[0020] In this embodiment, the positioning opening 6021 is a U-shaped structure, and elastic rubber pads adapted thereto are arranged on the inner sides of the positioning openings 6021, which can play a role of blocking and separating, making the test line connectors 5 correspond to the detection plugs 4 one by one. At the same time, the elastic rubber pads can also play a role of clamping and positioning the cables of the test line connectors 5.

[0021] In this embodiment, springs 607 are sleeved on the connecting rods 601 above the first pressing plate 604 and the second pressing plate 605 respectively, which are respectively used to push the first pressing plate 604 and the second pressing plate 605 to move downward. When the test line connector 5 is placed on the top of the first placing seat 602 or the second placing seat 603, the spring 607 pushes the first pressing plate 604 to overlap on the top of the first placing seat 602, and the second pressing plate 605 overlaps on the top of the second placing seat 603, which can play a role of pre-positioning the test line connector 5 and prevent the test line connector 5 from separating from the corresponding positioning opening 6021 due to cable twisting or the like. When placing the test line connector 5, only need to lift the first pressing plate 604 or the second pressing plate 605 upward, which is convenient to use.

[0022] Further, two positioning rods 7 are fixed on one side of the supporting vertical plate 2 close to the feeding mechanism 6, and the number can also be set to other values according to needs. Positioning holes 6022 matching the positioning rods 7 are provided on both the first placing seat 602 and the second placing seat 603. When the test line connector 5 on the first placing seat 602 or the second placing seat 603 is inserted into the detection plug 4, the positioning rod 7 is inserted into the positioning hole 6022, which further facilitates the insertion of the test line connector 5 and can support the feeding mechanism 6 at the same time.

[0023] Further, a guiding portion 701 with a gradually decreasing size is provided at one end of the positioning rod 7 away from the supporting vertical plate 2, which facilitates the insertion of the guiding portion 701 into the positioning hole 6022.

[0024] Working principle: First, a plurality of test line connectors 5 are placed on the top of the first placing seat 602, and the spring 607 pushes the first pressing plate 604 to press against the top of the test line connector 5 to achieve pre-positioning of the test line connector 5. During detection, the positioning rod 7 is inserted into the positioning hole 6022 on the first placing seat 602. At this time, each test line connector 5 is aligned with the detection plug 4 one by one. Then, the first placing seat 602 is pushed further toward the detection plug 4, and a plurality of test line connectors 5 can be correspondingly inserted into the detection plug 4 for detection at the same time. Meanwhile, the next batch of test line connectors 5 to be detected can be placed on the second placing seat 603. When the detection of the first placing seat 602 is completed, the first pressing plate 604 and the first placing seat 602 are pinched downward, and a plurality of test line connectors 5 can be pulled out at the same time. Then, the test line connectors 5 on the second placing seat 603 are inserted into the detection plug 4 for testing, which improves the detection efficiency.

[0025] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
