Description

Technical Field

[0001] The utility model relates to the technical field of circuit protection, in particular to an industrial automation control circuit protection device. Background Art

[0002] The leakage protector, also known as the leakage switch or leakage circuit breaker, is mainly used to protect against leakage faults in the equipment and to protect people from fatal electric shock. It has overload and short-circuit protection functions. It can be used to protect the line or motor from overload and short circuit. It can also be used as an infrequent switching start of the line under normal circumstances.

[0003] The circuit protection device in the prior art is a leakage protector, in which one end of the cable is inserted into a reserved socket, and then the bolt is tightened, and the extrusion force of the bolt is used to confine one end of the cable in the reserved hole to complete the installation of the line. The circuit protection device using this method is prone to cause one end of the cable to become loose. Since the bolt is directly used to fix one end of the cable after inserting one end of the cable into the reserved hole, the bolt fixation mainly relies on the friction between the bolt and the cable. Long-term use will inevitably cause the joint to become loose. Once loose, it will cause a short circuit, which seriously affects the use effect of the circuit protection device and reduces the use efficiency. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides the following technical solutions:

[0005] An industrial automation control circuit protection device comprises a main body, wherein the top and bottom surfaces of the main body are provided with wiring sockets for plugging in cables, and the front surface of the main body is threadedly connected with a fastening bolt inserted into the wiring socket; a limit extrusion block for pressing the cable is slidably arranged in the main body, and the limit extrusion block is located above the fastening bolt; a power mechanism for driving the limit extrusion block to move left and right is arranged in the main body, and the end of the power mechanism passes through the front surface of the main body.

[0006] As an improvement of the above technical solution, a slide groove is provided in the main body for the limiting extrusion block to slide left and right, and the slide groove is communicated with the wiring jack.

[0007] As an improvement of the above technical solution, the power mechanism includes a threaded rod and a first bevel gear. The threaded rod is rotatably arranged in the body. The outer periphery of the threaded rod is fixedly connected to the first bevel gear near one end of the threaded rod. The threaded rod is threadedly connected to the limiting extrusion block.

[0008] As an improvement of the above technical solution, the power mechanism also includes a second bevel gear and an adjusting rod. The second bevel gear is rotatably arranged in the main body, the second bevel gear is meshingly connected with the first bevel gear, one end of the second bevel gear is fixedly connected to the adjusting rod, the adjusting rod is rotatably connected to the main body, and the end of the adjusting rod passes through the front side of the main body.

[0009] As an improvement of the above technical solution, the end of the adjusting rod is provided with a groove which is the same as the end of the fastening bolt.

[0010] Beneficial effects of the utility model:

[0011] The sliding of the limiting extrusion block can make the cable inserted into the main body bend and deform, so that the cable is bent between the limiting extrusion block and the main body. At this time, even if the cable is pulled, the end of the cable will not move, thereby preventing the cable and the fastening bolt from moving. Long-term use can also prevent the cable joint from loosening, thereby improving service life and efficiency and ensuring stability of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] Please refer to Figure 1-Figure 4 As shown, the utility model provides an industrial automation control circuit protection device, including a body 1, the top and bottom surfaces of the body 1 are provided with wiring jacks 11 for plugging cables, and the front surface of the body 1 is threadedly connected with a fastening bolt 12 inserted into the wiring jack 11;

[0019] A limit extrusion block 22 for pressing the cable is slidably arranged in the body 1, and the limit extrusion block 22 is located above the fastening bolt 12;

[0020] A power mechanism for driving the limiting extrusion block 22 to move left and right is arranged in the main body 1 , and the end of the power mechanism passes through the front side of the main body 1 .

[0021] In the present case, by inserting the cable into the wiring jack 11 and then tightening the fastening bolt 12, the cable can be tightened by the end of the fastening bolt 12, and then by turning the power mechanism, the power mechanism can drive the limiting extrusion block 22 to slide left and right in the main body 1, so that the cable can be squeezed, so that the cable is bent and deformed, and the cable is fastened in the main body 1, avoiding looseness at the joint between the cable and the fastening bolt 12.

[0022] Among them, the sliding of the limiting extrusion block 22 can make the cable inserted into the main body 1 bend and deform, so that the cable is bent between the limiting extrusion block 22 and the main body 1. At this time, even if the cable is pulled, the end of the cable will not move, thereby preventing the cable and the fastening bolt 12 from moving. Long-term use can also prevent the cable joint from loosening, thereby improving service life and efficiency and ensuring stability of use.

[0023] A slide groove 13 is provided in the body 1 for the limit extrusion block 22 to slide left and right, and the slide groove 13 is communicated with the wiring jack 11 .

[0024] The power mechanism includes a threaded rod 2 and a first bevel gear 21 . The threaded rod 2 is rotatably arranged in the body 1 . The outer periphery of the threaded rod 2 is fixedly connected to the first bevel gear 21 near one end of the threaded rod 2 . The threaded rod 2 is threadedly connected to the limiting extrusion block 22 .

[0025] The slide groove 13 is provided to facilitate the sliding of the limiting extrusion block 22. The threaded rod 2 is threadedly connected to the limiting extrusion block 22. The rotation of the threaded rod 2 can drive the limiting extrusion block 22 to slide in the slide groove 13. The sliding of the limiting extrusion block 22 can squeeze the cable, causing the cable to deform. After deformation, the cable is crimped between the limiting extrusion block 22 and the body 1, thereby limiting the cable and squeezing and tightening the cable to prevent the cable end from loosening.

[0026] The power mechanism also includes a second bevel gear 3 and an adjusting rod 31. The second bevel gear 3 is rotatably arranged in the main body 1. The second bevel gear 3 is meshed and connected with the first bevel gear 21. One end of the second bevel gear 3 is fixedly connected to the adjusting rod 31. The adjusting rod 31 is rotatably connected to the main body 1, and the end of the adjusting rod 31 passes through the front of the main body 1.

[0027] The end of the adjusting rod 31 is provided with a groove which is the same as the end of the fastening bolt 12 .

[0028] Through the setting of the adjusting rod 31, the end of the adjusting rod 31 passes through the front side of the body 1, and the end of the adjusting rod 31 is provided with a groove which is the same as the end of the fastening bolt 12, wherein the groove is a socket for inserting a screwdriver. After the cable is fastened in the wiring socket 11, the adjusting rod 31 is turned with a screwdriver to drive the second bevel gear 3 to rotate, and the second bevel gear 3 is meshed and linked with the first bevel gear 21, so that the rotation of the second bevel gear 3 can drive the first bevel gear 21 to rotate, and the first bevel gear 21 drives the threaded rod 2 to rotate, and the threaded rod 2 drives the limiting extrusion block 22 to slide in the slide groove 13, thereby completing the extrusion and limiting of the cable.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
