[0002] Terminal blocks are electrical components used to connect wires. Their main function is to connect power sources, equipment, and external interfaces to wire harnesses for transmitting electrical energy and signals. In circuits, terminal blocks can connect wires to other electrical equipment or circuits to ensure the normal operation of the circuit.

[0003] When using the terminal blocks, insert the cable into the wiring slot on one side of the housing, then turn the first bolt until it reaches the cable in the wiring slot inside the housing, and then secure the cable. When some wiring slots on the housing are not in use, debris can easily accumulate inside, preventing the insertion of wires into those slots during subsequent use, thus affecting the effectiveness of the terminal block structure. Utility Model Content

[0004] This utility model proposes a protective terminal structure to address the problem that when some wiring slots on the outer casing are not in use, debris can easily accumulate inside, preventing the insertion of wires into these slots during subsequent use and thus affecting the effectiveness of the terminal structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective terminal block structure, including a housing, a plurality of wiring grooves on one side of the housing, a plurality of first bolts on one side of the housing, wires in the wiring grooves on one side of the housing, a protective device on the side of the housing near the wiring grooves, the protective device including a fixing plate, one side of the fixing plate being fixedly connected to the housing, a plurality of through holes on one side of the fixing plate, a protective plate being slidably connected inside the through holes on one side of the fixing plate, a second bolt being threadedly connected to one side of the protective plate, a plurality of threaded grooves on one side of the fixing plate, one side of the second bolt being threadedly connected to the threaded grooves on one side of the fixing plate, and a control frame being fixedly connected to one side of the protective plate.

[0006] The aforementioned components achieve the following effect: When using the terminal block, insert the cable into the wiring slot on one side of the housing, then rotate the first bolt to bring it into contact with the cable in the wiring slot inside the housing, thus securing the cable. When some wiring slots on one side of the housing are not in use, the protective plate inside the through hole on one side of the fixing plate can be moved using the control bracket, allowing the protective plate to slide inside the fixing plate. This protects the unused wiring slots on the housing. Then, rotate the second bolt to pass through the protective plate and fix it to the threaded groove on one side of the fixing plate, thus completing the fixation of the protective plate. By using the protective device, unused wiring slots on the housing can be protected, preventing debris from easily accumulating inside these slots and thus preventing wires from being inserted into some wiring slots during subsequent use. This improves the usability of the terminal block structure.

[0007] Preferably, the protective plate is fixedly connected to both sides with arc strips, and the arc surface of the arc strips is close to the inner wall of the through hole on one side of the fixed plate.

[0008] The effect achieved by the above components is to reduce the friction between the protective plate and the through hole on one side of the fixed plate by using the arc strip, making it easier for the operator to move the protective plate.

[0009] Preferably, two sponge blocks are fixedly connected to the side of the protective plate near the outer shell, and the size of the two sponge blocks is adapted to the size of the protective plate.

[0010] The effect achieved by the above components is to improve the sealing between the protective plate and the outer shell by using sponge blocks, thereby improving the performance of the protective plate.

[0011] Preferably, a connecting rope is fixedly connected to one side of the second bolt, and one side of the connecting rope is fixedly connected to the protective plate.

[0012] The effect achieved by the above components is to connect the second bolt to the protective plate by using a connecting rope, thereby preventing the second bolt from being lost.

[0013] Preferably, a rubber sleeve is fixedly connected to one side of the control frame, and the size of the rubber sleeve is adapted to the control frame.

[0014] The effect achieved by the above components is to increase the friction between the control frame and the operator by using a rubber sleeve, making it easier for the operator to grip the control frame and use it.

[0015] Preferably, the outer casing is provided with a plurality of support devices on the side near the wiring groove. The plurality of support devices include a mounting block, the mounting block is fixedly connected to the outer casing, a third bolt is inserted into the internal thread of the mounting block, a support frame is threaded into one side of the third bolt, and a support ring is fixedly connected to one side of the support frame. The size of the support ring is adapted to the size of the wire.

[0016] The effect achieved by the above components is as follows: when the wire is inserted into the wiring slot on one side of the housing, the support frame can be moved to insert into the mounting block. Then, the third bolt is rotated to pass through the mounting block and fix it to the support frame. Then, the support ring is fixed to the side of the housing near the wiring slot. When the wire is inserted into the wiring slot on one side of the housing, it needs to pass through the support ring first and be supported and limited by the support ring. By using the support device, the side of the wire near the housing can be supported, avoiding excessive bending of the wire near the housing and damage to the wire sheath.

[0017] Preferably, a washer is abutted on the side of the third bolt near the mounting block, and one side of the washer abuts against the mounting block.

[0018] The effect achieved by the above components is to increase the contact area between the third bolt and the mounting block by using a shim, thereby making the third bolt more securely fixed to the support frame.

[0019] Preferably, two guide plates are fixedly connected to one side of the mounting block, and the two guide plates are inclinedly arranged on one side of the mounting block.

[0020] The effect achieved by the above components is to increase the size of the mounting block's inlet and outlet by using a guide plate, making it easier for the support frame to be inserted into the mounting block.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using protective devices, unused wiring slots on the housing can be shielded and protected, preventing debris from easily accumulating inside these slots and causing situations where wires cannot be inserted into some of the wiring slots during subsequent use. This improves the usability of the terminal block structure. Attached Figure Description

[0028] Reference Figure 1-4 As shown, this embodiment discloses a protective terminal structure, including a housing 1, a plurality of wiring grooves 4 on one side of the housing 1, a plurality of first bolts 5 on one side of the housing 1, wires 6 in the wiring grooves 4 on one side of the housing 1, and a protective device 2 on the side of the housing 1 near the wiring grooves 4.

[0029] Reference Figure 1-4 As shown, this embodiment discloses a protective device 2 including a fixing plate 21. One side of the fixing plate 21 is fixedly connected to the outer casing 1. A plurality of through holes 22 are provided on one side of the fixing plate 21. A protective plate 23 is slidably connected inside the through holes 22 on one side of the fixing plate 21. A second bolt 24 is threadedly connected to one side of the protective plate 23. A plurality of threaded grooves 25 are provided on one side of the fixing plate 21. One side of the second bolt 24 is threadedly connected to the threaded grooves 25 on one side of the fixing plate 21. A control frame 26 is fixedly connected to one side of the protective plate 23. When using the terminal block, the cable is inserted into the wiring groove 4 on one side of the outer casing 1, and then the first bolt 5 is rotated to bring the first bolt 5 to the cable in the wiring groove 4 inside the outer casing 1, and then the cable is fixed. When the wiring slots 4 on one side of the housing 1 are not in use, the protective plate 23 inside the through hole 22 on one side of the fixing plate 21 can be moved by the control bracket 26, so that the protective plate 23 slides inside the fixing plate 21, and then the fixing plate 21 shields and protects the unused wiring slots 4 on the housing 1. Then, the second bolt 24 is rotated so that the second bolt 24 passes through the protective plate 23 and is fixed to the threaded groove 25 on one side of the fixing plate 21, and then the position of the protective plate 23 is fixed. By using the protective device 2, the unused wiring slots 4 on the housing 1 can be shielded and protected, so as to avoid the inside of the unused wiring slots 4 being prone to debris, which would cause the wiring slots 4 on the housing 1 to be unable to insert wires 6 during subsequent use, thereby improving the performance of the terminal block structure.

[0030] Reference Figure 1-4As shown, this embodiment discloses that arc strips 27 are fixedly connected to both sides of the protective plate 23, and the arc surface of the arc strips 27 is close to the inner wall of the through hole 22 on one side of the fixed plate 21. By using the arc strips 27, the friction between the protective plate 23 and the through hole 22 on one side of the fixed plate 21 is reduced, making it easier for the operator to move the protective plate 23. Two sponge blocks 28 are fixedly connected to the side of the protective plate 23 near the outer shell 1, and the size of the two sponge blocks 28 is adapted to the size of the protective plate 23. By using the sponge blocks 28, the sealing between the protective plate 23 and the outer shell 1 is improved, thereby improving the performance of the protective plate 23. A connecting rope 29 is fixedly connected to one side of the second bolt 24, and one side of the connecting rope 29 is fixedly connected to the protective plate 23. By using the connecting rope 29, the second bolt 24 is connected to the protective plate 23, preventing the second bolt 24 from being lost. A rubber sleeve 210 is fixedly connected to one side of the control frame 26, and the size of the rubber sleeve 210 is adapted to the size of the control frame 26. By using a rubber sleeve 210, the friction between the control frame 26 and the operator is increased, making it easier for the operator to grip the control frame 26 for use.

[0031] Reference Figure 1-4 As shown in the figure, this embodiment discloses that the outer casing 1 is provided with several support devices 3 on the side near the wiring groove 4. The several support devices 3 include a mounting block 31, which is fixedly connected to the outer casing 1. A third bolt 32 is inserted into the internal thread of the mounting block 31. A support frame 33 is threaded into one side of the third bolt 32. A support ring 34 is fixedly connected to one side of the support frame 33. The size of the support ring 34 is adapted to the size of the wire 6. When the wire 6 is inserted into the wiring groove 4 on the side of the outer casing 1, the support frame 33 can be moved to insert into the mounting block 31. Then, the third bolt 32 is rotated to pass through the mounting block 31 and be fixed to the support frame 33. Then, the support ring 34 is fixed to the side of the outer casing 1 near the wiring groove 4. When the wire 6 is inserted into the wiring groove 4 on the side of the outer casing 1, it needs to pass through the support ring 34 first to be supported and limited by the support ring 34. By using the support devices 3, the side of the wire 6 near the outer casing 1 can be supported, avoiding excessive bending of the wire 6 near the outer casing 1, which would cause damage to the wire sheath.

[0032] Reference Figure 1-4 As shown, this embodiment discloses that a washer 35 is abutted against the side of the third bolt 32 near the mounting block 31, and one side of the washer 35 abuts against the mounting block 31. By using the washer 35, the contact area between the third bolt 32 and the mounting block 31 is increased, thereby making the third bolt 32 more securely fixed to the support frame 33. Two guide plates 36 are fixedly connected to one side of the mounting block 31, and the two guide plates 36 are obliquely arranged on one side of the mounting block 31. By using the guide plates 36, the size of the entrance and exit of the mounting block 31 is increased, making it easier for the support frame 33 to be inserted into the mounting block 31.

[0033] Working principle: When using the terminal block, insert the cable into the wiring slot 4 on one side of the housing 1, then rotate the first bolt 5 to bring it into contact with the cable in the wiring slot 4 inside the housing 1, and then fix the cable. When some wiring slots 4 on one side of the housing 1 are not in use, the protective plate 23 inside the through hole 22 on one side of the fixing plate 21 can be moved by the control bracket 26, so that the protective plate 23 slides inside the fixing plate 21, and then the fixing plate 21 protects the unused wiring slots 4 on the housing 1. Then rotate the second bolt 24 to pass through the protective plate 23 and fix it to the threaded groove 25 on one side of the fixing plate 21, and then the position of the protective plate 23 is fixed. By using the protective device 2, the unused wiring slots 4 on the housing 1 can be protected, avoiding the accumulation of debris inside the unused wiring slots 4, which could prevent the insertion of wires 6 into some wiring slots 4 on the housing 1 during subsequent use, thereby improving the performance of the terminal block structure.

[0034] When the wire 6 is inserted into the wiring slot 4 on one side of the housing 1, the support frame 33 can be moved so that the support frame 33 is inserted into the mounting block 31 with the guide plate 36. Then, the third bolt 32 is rotated so that the third bolt 32 passes through the washer 35 and the mounting block 31 and is fixed to the support frame 33. Then, the support ring 34 is fixed to the side of the housing 1 near the wiring slot 4. When the wire 6 is inserted into the wiring slot 4 on one side of the housing 1, it needs to pass through the support ring 34 first so that it can be supported and limited by the support ring 34. By using the support device 3, the side of the wire 6 near the housing 1 can be supported to avoid the wire 6 being bent due to excessive force on the side of the wire 6 near the housing 1, which would cause damage to the surface of the wire 6.
