Description

Technical Field

[0001] This utility model relates to the field of PLC module testing technology, and in particular to a connection testing device for PLC modules. Background Technology

[0002] PLC modules refer to the various functional parts of a programmable logic controller system. A PLC is a device specifically designed for industrial automation control. Through pre-programmed logic rules, it enables automated control of industrial equipment, improving production efficiency, quality, and safety.

[0003] When testing a PLC module, an external cable is needed to connect the PLC module to the detector. Since the PLC module has many connection holes, multiple connecting cables are required. As a result, the connecting cables become tangled together in a mess, making it difficult to clearly see which hole the connecting cable is inserted into. It requires manual searching along the connecting cables, which brings a huge amount of work. Utility Model Content

[0010] In addition, in a preferred configuration, the top and bottom of the second semicircular sleeve are fixedly mounted with an annular sleeve by self-tapping screws, the annular sleeve is fitted onto the fixing post, and a locking hook adapted to the locking groove is provided on one side of the second semicircular sleeve.

[0011] Furthermore, in a preferred configuration, the limiting strip and locking hook are made of a highly elastic material.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-6A connection detection device for a PLC module includes a detector body 2, a placement platform 6 fixedly mounted on the top of the detector body 2 by screws, a PLC module 1 placed in the placement platform 6, a plurality of socket holes 22 opened on the side of the detector body 2, a plurality of cable holders 4 fixedly mounted on the side of the detector body 2 by screws, a control center 21 provided on the side of the detector body 2, and a plurality of cable grooves 23 opened on the top of the detector body 2, with limit strips 3 provided above the cable grooves 23.

[0023] Among them, a limiting strip 3 is provided on the top of the detector body 2 above the wire groove 23. One end of the limiting strip 3 is fixedly installed on the top of the detector body 2, and the other end of the limiting strip 3 can move freely.

[0024] Meanwhile, the detector body 2 has a limiting groove 24 that is adapted to the limiting strip 3, and the limiting groove 24 is located on one side of the wire groove 23.

[0025] Meanwhile, the cable fastener 4 includes a first semicircular sleeve 5 and a second semicircular sleeve 7. A locking groove 52 is provided on one side of the first semicircular sleeve 5, and a fixing post 51 is fixedly installed on the other side of the first semicircular sleeve 5.

[0026] Meanwhile, the top and bottom of the second semicircular sleeve 7 are fixedly installed with the annular sleeve 72 by self-tapping screws 73. The annular sleeve 72 is sleeved on the fixed post 51. A locking hook 71 that matches the locking groove 52 is provided on one side of the second semicircular sleeve 7.

[0027] Furthermore, the limiting strip 3 and the locking hook 71 are made of a highly elastic material.

[0028] In this embodiment, by inserting the connector plug into the socket 22 and then placing the connector wire into the wire groove 23, the limiting strip 3 is made of a highly elastic material. Therefore, by bending the free end of the limiting strip 3, it is inserted into the limiting groove 24, thus confining the connector wire within the wire groove 23 and preventing it from protruding. Since the locking hook 71 is also made of a highly elastic material, squeezing the locking hook 71 by hand pushes it out of the locking groove 52. Then, rotating the second semicircular sleeve 7 causes the annular sleeve 72 to rotate around the fixed 51, thereby driving the second semicircular sleeve 7... The sleeve 7 rotates around the fixed 51, thereby opening the cable retainer 4. Then, the connecting wire is placed into the first semicircular sleeve 5. The second semicircular sleeve 7 is rotated and pressed to make the locking hook 71 enter the locking groove 52 for locking, thereby closing the cable retainer 4 and fixing the connecting wire in the cable retainer 4. Then, the connecting wire is placed into the wire groove 23, and the limiting strip 3 is inserted into the limiting groove 24 to restrict the connecting wire within the wire groove 23. Then, the connecting wire plug is inserted into the hole of the PLC module, thus clearly showing which hole each connecting wire is connected to.

[0029] In this invention, by placing the connecting wire into the wire groove 23 and then using the limiting strip 3 to confine it within the wire groove 23, and then placing the connecting wire in the wire holder 4, the connecting wire connects the PLC module 1 to the detector. This makes it clear which hole each connecting wire is connected to, eliminating the need to manually search along the connecting wire and greatly reducing the workload.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
