Description

Technical Field

[0001] This utility model relates to the field of copper terminal block technology, and in particular to a waterproof copper terminal block. Background Technology

[0002] Copper terminals are made of copper and are used for transitional connections between copper core cables and the copper ends of electrical equipment. They are mainly used in power distribution devices to connect wires, power cables and electrical equipment, ensuring that current can be transmitted stably and safely.

[0003] Traditional copper terminal blocks play an important role in electrical connections, but their waterproof performance is often insufficient in humid or underwater environments, which can easily lead to safety hazards. In the prior art, waterproof heat shrink tubing is usually wrapped around the outer surface of the copper terminal block and the cable connection for waterproofing. Although the waterproof heat shrink tubing has a certain sealing performance, in some cases, such as long-term immersion in water or impact by high-pressure water flow, its waterproof performance may be reduced or damaged, making it inconvenient to use. This utility model provides an alternative solution. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof copper terminal block.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof copper terminal block, comprising a copper terminal block body, bolts symmetrically connected to one side of the copper terminal block body, cables inserted into the inner walls of both ends of the copper terminal block body, a waterproof sealing device provided on the outer surface of the copper terminal block body, and limit devices provided between the two ends of the copper terminal block body and the cables, the waterproof sealing device comprising two first protective sleeves and two second protective sleeves, a groove frame fixedly connected to the outer surface of the copper terminal block body, and a first sealing device fixedly connected to one side of the inner wall of both ends of the groove frame. The first protective sleeve is fitted onto the outer surface of one end of the copper terminal block body, and the other end is threaded to the inner wall of one end of the groove frame. A threaded tube is fixedly connected to one side of the first protective sleeve, and several rectangular grooves are opened on one side of the threaded tube. A second sealing block is fixedly connected to one side of the first protective sleeve at the outer surface of one end of the threaded tube. The inner wall of one end of the second protective sleeve is threaded to the outer surface of one end of the threaded tube. The longitudinal section of one end of the second protective sleeve is trapezoidal. A third sealing block is fixedly connected to the inner wall of one end of the second protective sleeve. The cable is inserted into the inner walls of the second protective sleeve, the threaded tube, and the first protective sleeve.

[0006] The effect achieved by the above components is as follows: By setting up a waterproof sealing device, when connecting two cables using the copper terminal block body, the second protective sleeve, the threaded tube, and the first protective sleeve are first sequentially placed on the outer surface of the cable, so that the third sealing block inside one end of the inner wall of the second protective sleeve is tightly fitted to the outer surface of the cable. Then, the cable is fixed in the inner wall of the copper terminal block body, and the first protective sleeve is screwed into the inner wall of the groove frame and sealed by the first sealing block. Then, the second protective sleeve is screwed into the outer surface of the threaded tube to compress it, and the interface is sealed by the second sealing block. The inner walls of one end of the cable and the second protective sleeve are sealed by the third sealing block. In this way, the copper terminal block body and the interface with the cable can be completely covered and sealed, so that it is not easy to cause safety hazards when used in humid or underwater environments, thus improving the safety of use.

[0007] Preferably, the outer surfaces of the first protective sleeve and the second protective sleeve are each fixedly connected with a plurality of protrusions, and the plurality of protrusions are arranged at equal intervals.

[0008] The effect achieved by the above-mentioned components is that by setting protrusions, the roughness of the outer surfaces of the first and second protective sleeves can be increased, making it easier to manually grip and twist them.

[0009] Preferably, a plurality of elastic silicone blocks are fixedly connected to the inner wall of one end of the threaded tube, and the elastic silicone blocks are disposed in the inner wall of the end of the threaded tube away from the first protective sleeve.

[0010] The effect achieved by the above components is as follows: by setting up the elastic silicone block, when the second protective sleeve is squeezing the threaded tube, one end of the threaded tube will shrink and gather, and one side of the elastic silicone block will abut against the outer surface of the cable, thus preventing damage to the cable.

[0011] Preferably, a third protective sleeve is fixedly connected to one side of the first protective sleeve, and the third protective sleeve is fitted onto the outer surface of the second sealing block away from the threaded tube.

[0012] The effect achieved by the above components is that by setting a third protective sleeve, the outer surface of the second sealing block can be protected, reducing the area in contact with air, avoiding aging and damage, and improving service life.

[0013] Preferably, the limiting device includes a circular ring block, the inner wall of which is fixedly connected to the outer surface of the cable, and a plurality of slots are formed on the outer surface of the circular ring block. Circular hole blocks are fixedly connected to both ends of the copper terminal body, and a locking block is slidably connected to the inner wall of the circular hole block. A spring is sleeved on the outer surface of one end of the locking block, and both ends of the spring are fixedly connected to one side of the locking block and the circular hole block, respectively. One end of the locking block is inserted into the inner wall of the slot.

[0014] The effect achieved by the above-mentioned components is as follows: by setting a limiting device, before installation, the locking block can be pulled outward to a certain position in the inner wall of the round hole block, causing the spring to stretch. Then, after the cable is inserted into the copper terminal body and fixed, the locking block is released, so that under the reset action of the spring, one end can be locked into the corresponding slot, thus fixing and limiting the cable a second time, making it less likely to loosen or fall off during use and improving the stability during use.

[0015] Preferably, an anti-slip block is fixedly connected to one end of the outer surface of the card block, and the anti-slip block is made of rubber.

[0016] The effect achieved by the above components is that by setting anti-slip blocks, the gap between the outer surface of one end of the block and the inner wall of the slot can be sealed, making the block less prone to shaking when it is in the limiting position, and the limiting is more secure.

[0017] Preferably, a pull block is fixedly connected to one side of the locking block, and the pull block is disposed on the side of the locking block near the spring.

[0018] The effect achieved by the above components is that by setting up the pull block, the contact area at one end of the block can be increased, making it easier to manually hold and pull it.

[0019] Preferably, a reinforcing rod is fixedly connected to both sides of one end of the circular hole block, and one side of the reinforcing rod is fixedly connected to one side of the copper terminal body.

[0020] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the round hole block and the copper terminal body can be increased, making the connection more secure and stable.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a waterproof sealing device, when connecting two cables using the copper terminal block body, the second protective sleeve, the threaded tube, and the first protective sleeve are first sequentially placed on the outer surface of the cable, so that the third sealing block inside one end of the inner wall of the second protective sleeve is tightly fitted to the outer surface of the cable. Then, the cable is fixed in the inner wall of the copper terminal block body, and the first protective sleeve is screwed into the inner wall of the groove frame and sealed by the first sealing block. Then, the second protective sleeve is screwed into the outer surface of the threaded tube to compress it, and the interface is sealed by the second sealing block. The inner walls of one end of the cable and the second protective sleeve are sealed by the third sealing block. In this way, the copper terminal block body and the interface with the cable can be completely covered and sealed, so that it is not easy to cause safety hazards when used in humid or underwater environments, thus improving the safety of use.

[0028] Example 1, as Figure 1-4As shown, a waterproof copper terminal block includes a copper terminal block body 1. Bolts 4 are symmetrically connected to one side of the copper terminal block body 1. Cables 5 are inserted into the inner walls of both ends of the copper terminal block body 1. A waterproof sealing device 2 is provided on the outer surface of the copper terminal block body 1. Limiting devices 3 are provided between the two ends of the copper terminal block body 1 and the cables 5. The waterproof sealing device 2 includes two first protective sleeves 23 and two second protective sleeves 27. A groove frame 21 is fixedly connected to the outer surface of the copper terminal block body 1. A first sealing block 22 is fixedly connected to one side of the inner wall of both ends of the groove frame 21. The first protective sleeves 23 are sleeved on the copper terminal block. One end of the outer surface of the sub-body 1 is threaded to the inner wall of one end of the groove frame 21. A threaded tube 24 is fixedly connected to one side of the first protective sleeve 23. Several rectangular grooves 25 are opened on one side of the threaded tube 24. A second sealing block 26 is fixedly connected to one side of the first protective sleeve 23 at one end of the outer surface of the threaded tube 24. One end of the inner wall of the second protective sleeve 27 is threaded to the outer surface of one end of the threaded tube 24. One end of the second protective sleeve 27 has a trapezoidal longitudinal section. A third sealing block 28 is fixedly connected to one end of the inner wall of the second protective sleeve 27. The cable 5 is inserted into the inner walls of the second protective sleeve 27, the threaded tube 24 and the first protective sleeve 23. When connecting two cables 5 using the copper terminal block body 1, first, the second protective sleeve 27, the threaded tube 24, and the first protective sleeve 23 are sequentially fitted onto the outer surface of the cable 5, ensuring that the third sealing block 28 inside one end of the inner wall of the second protective sleeve 27 is tightly fitted against the outer surface of the cable 5. Then, one end of the insulation of the cable 5 is removed, exposing the copper core, which is then inserted into the inner wall of the copper terminal block body 1. The bolt 4 is then tightened to secure it to the inner wall of the copper terminal block body 1. At this point, one end of the first protective sleeve 23 is threaded into the inner wall of the groove bracket 21, so that one side abuts against and presses against the first sealing block 22, protecting one end of the copper terminal block body 1. Finally, the second protective sleeve 27 is pulled onto the cable 5 to a fixed position. The inner wall of the second protective sleeve 27 is threaded onto the outer surface of the threaded tube 24, and one end of the threaded tube 24 is squeezed, causing it to shrink within the gap of the rectangular groove 25. At the same time, one side of the second protective sleeve 27 abuts against one side of the second sealing block 26, sealing the second protective sleeve 27 and the outer surface of the threaded tube 24. The squeezed and shrunken end of the threaded tube 24 abuts against the outer surface of the cable 5, fixing and limiting it to prevent it from shaking. Similarly, the other end of the copper terminal body 1 is operated in the same way, sealing and protecting it as well. This completely covers and seals the copper terminal body 1 and the interface with the cable 5, making it less likely to cause safety hazards when used in humid or underwater environments, improving safety and convenience of use.

[0029] Reference Figure 2 and Figure 3As shown in the figure, this embodiment discloses that the outer surfaces of both the first protective sleeve 23 and the second protective sleeve 27 are fixedly connected with a plurality of protrusions 29, which are arranged at equal intervals. By setting the protrusions 29, the roughness of the outer surfaces of the first protective sleeve 23 and the second protective sleeve 27 can be increased, making it easier to manually grip and tighten them. A plurality of elastic silicone blocks 210 are fixedly connected to the inner wall of one end of the threaded tube 24, and the elastic silicone blocks 210 are disposed in the inner wall of the end of the threaded tube 24 away from the first protective sleeve 23. By setting the elastic silicone blocks 210, when the second protective sleeve 27 squeezes the threaded tube 24, the end of the threaded tube 24 contracts and gathers, which will abut one side of the elastic silicone block 210 against the outer surface of the cable 5, thus preventing damage to the cable 5.

[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a third protective sleeve 211 fixedly connected to one side of the first protective sleeve 23. The third protective sleeve 211 is fitted onto the outer surface of the second sealing block 26 away from the threaded tube 24. By providing the third protective sleeve 211, the outer surface of the second sealing block 26 can be protected, reducing the area in contact with air, avoiding aging and damage, and improving service life.

[0031] Reference Figure 4 As shown, this embodiment discloses a limiting device 3 including a circular block 31. The inner wall of the circular block 31 is fixedly connected to the outer surface of the cable 5. Several slots 32 are formed on the outer surface of the circular block 31. Circular hole blocks 33 are fixedly connected to both ends of the copper terminal body 1. A locking block 34 is slidably connected to the inner wall of the circular hole block 33. A spring 35 is sleeved on the outer surface of one end of the locking block 34. The two ends of the spring 35 are fixedly connected to one side of the locking block 34 and the circular hole block 33, respectively. One end of the locking block 34 is inserted into the inner wall of the slot 32. Before installation, the locking block 34 can be pulled outward to a certain position in the inner wall of the circular hole block 33, causing the spring 35 to stretch. After the cable 5 is inserted into the copper terminal body 1 and fixed, the locking block 34 is released, allowing one end to be locked into the corresponding slot 32 under the reset action of the spring 35. This provides secondary fixing and limiting of the cable 5, making it less prone to loosening and falling off during use, thus improving stability during use.

[0032] Reference Figure 4As shown, this embodiment discloses that an anti-slip block 36, made of rubber, is fixedly connected to the outer surface of one end of the locking block 34. By setting the anti-slip block 36, the gap between the outer surface of one end of the locking block 34 and the inner wall of the locking groove 32 can be sealed, making the locking block 34 less prone to shaking when in the limiting position, and making the limiting more secure. A pull block 37 is fixedly connected to one side of the locking block 34, and the pull block 37 is located on the side of the locking block 34 near the spring 35. By setting the pull block 37, the contact area of ​​one end of the locking block 34 can be increased, making it easier to manually grasp and pull it. Reinforcing rods 38 are fixedly connected to both sides of one end of the round hole block 33, and one side of the reinforcing rod 38 is fixedly connected to one side of the copper terminal body 1. By setting the reinforcing rod 38, the connection area between the round hole block 33 and the copper terminal body 1 can be increased, making the connection more secure and stable.

[0033] Working principle: When connecting two cables 5 using the copper terminal block body 1, firstly, the second protective sleeve 27, the threaded tube 24, and the first protective sleeve 23 are sequentially fitted onto the outer surface of the cable 5, ensuring that the inner wall of the third sealing block 28 at one end of the second protective sleeve 27 is tightly fitted against the outer surface of the cable 5. Then, one end of the insulation of the cable 5 is removed, exposing the copper core, which is then inserted into the inner wall of the copper terminal block body 1. The bolt 4 is then tightened to secure it to the inner wall of the copper terminal block body 1. At this point, one end of the first protective sleeve 23 is threaded into the inner wall of the groove bracket 21, so that one side abuts against and presses against the first sealing block 22, protecting one end of the copper terminal block body 1. Finally, the second protective sleeve 27 is pulled along the cable 5. At a certain position, one end of the inner wall of the threaded tube 24 is fitted onto the outer surface of the threaded tube 24. This compresses one end of the threaded tube 24, causing it to contract within the gap of the rectangular groove 25. Simultaneously, one side of the second protective sleeve 27 abuts against one side of the second sealing block 26, sealing the second protective sleeve 27 and the outer surface of the threaded tube 24. The compressed and contracted end of the threaded tube 24 abuts against the outer surface of the cable 5, fixing and limiting it to prevent it from shaking. Similarly, the other end of the copper terminal body 1 is subjected to the same operation, with its other end also sealed and protected. This completely covers and seals the copper terminal body 1 and the interface with the cable 5, making it less likely to cause safety hazards when used in humid or underwater environments, improving safety and convenience of use.

[0034] Before installation, the locking block 34 can be pulled outward to a certain position in the inner wall of the round hole block 33, causing the spring 35 to stretch. After the cable 5 is inserted into the copper terminal body 1 and fixed, the locking block 34 is released, so that one end can be locked into the corresponding slot 32 under the reset action of the spring 35, thus fixing and limiting the cable 5 for the second time, making it less likely to loosen or fall off during use and improving the stability during use.
