Description

Technical Field

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

[0002] Terminal blocks are electrical components used to connect and secure wires. They are widely used in various electrical equipment and systems, ensuring efficient and stable transmission of current or signals by providing a safe and reliable connection point. In many applications, especially in humid or outdoor environments, the terminals are easily exposed to moisture or liquids. If the terminals are not waterproof, moisture can enter the terminal block along the wires, causing electrical short circuits, corrosion, and other malfunctions, severely impacting the safety and reliability of the equipment. Therefore, waterproof design of the terminal block terminals is crucial to improve their stability and lifespan in harsh environments.

[0003] In the prior art, most existing terminal blocks do not have a specially designed waterproof structure. During use, the connection between the terminal block and the wire is not waterproof. This allows moisture to enter the terminal block along the wire when it is exposed to a humid environment or splashed with water. Once moisture enters, it may cause short circuits, reduced insulation performance, or even serious electrical faults, thereby damaging the entire circuit system and further reducing the service life and reliability of the terminal block. Therefore, this utility model proposes a terminal block with waterproof function to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof terminal block to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a waterproof terminal block, comprising: a terminal block body, a groove on one side of the terminal block body, the groove abutting against one side of a sealing ring, the other side of the sealing ring being fixedly connected to one side of a waterproof cover, a transparent cover plate being fixedly installed on the other side of the waterproof cover, and anti-slip support blocks being fixedly connected to the middle of the two side walls of the terminal block body.

[0006] The waterproof cover is fixedly connected to both sides with mounting plates. The mounting plates are slidably connected to the anti-slip support blocks. A limit plate is fixedly installed on one side of the mounting plate. A U-shaped rod is slidably sleeved inside the limit plate. One end of the U-shaped rod is slidably inserted into the mounting plate. The limit plate is fixedly connected to one end of a spring. The other end of the spring is fixedly connected to a limit piece. The limit piece is fixedly sleeved on the U-shaped rod.

[0007] Preferably, the mounting plate has two sets of four in total, which are symmetrically arranged about the central plane of the waterproof cover. A limit hole is opened on one side surface of the mounting plate, and the limit hole is slidably inserted into one end of the U-shaped rod.

[0008] Preferably, the limiting plate is fixedly connected to both sides of the terminal block body, the surface of the limiting plate is provided with sliding holes, the sliding holes and U-shaped rods are slidably connected, and the upper surface of the waterproof cover is provided with ventilation holes, which are arranged in a linear array.

[0009] Preferably, a drying box is provided above the ventilation hole, and a dustproof mesh is provided below the ventilation hole. The drying box, the dustproof mesh, and the waterproof cover are all fixedly connected by small bolts.

[0010] Preferably, one side of the waterproof cover is fixedly connected to the transparent cover plate by a large bolt. The transparent cover plate has positioning holes on the side away from the terminal block body, and the positioning holes are arranged in a linear array about one side of the transparent cover plate.

[0011] Preferably, the positioning hole is fixedly connected to one end of the positioning sleeve, the outer ring surface of the other end of the positioning sleeve is threaded with a threaded sleeve, the inner ring surface of the other end of the positioning sleeve is slidably fitted with an elastic clip, and one end of the elastic clip is fixedly connected with a rubber block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The waterproof cover is fixed to the side of the terminal block body near the wiring groove by the mounting plate. The waterproof cover and the sealing ring further enhance the waterproof function, thereby preventing moisture from entering the terminal block when the wiring port of the terminal block body is exposed to a humid environment or splashed with water, which could cause serious electrical faults and damage the entire circuit system.

[0014] 2. By twisting the threaded connection of one end of the positioning sleeve, the screw sleeve moves closer to the terminal body. The screw sleeve presses the elastic clamp into the positioning sleeve, and then the four branches of the elastic clamp continuously contract, which in turn causes the rubber block to clamp the wire. This not only secures the wire but also increases the seal between the wire and the clamp, preventing moisture from entering the interior of the terminal body along the wire.

[0015] 3. A drying box is installed on the upper side through the ventilation hole. The drying box is filled with drying particles to adsorb moisture in the circulating air, thereby preventing the inside of the waterproof cover from becoming damp and further realizing the waterproof function. A dustproof mesh plate is fixedly installed on the lower side of the drying box, which can filter dust in the flowing air and prevent external impurities from entering the inside of the terminal body and affecting the service life of electronic components.

[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 5This utility model provides a technical solution: a waterproof terminal block, comprising: a terminal block body 1, the terminal block body 1 including a wiring groove, a groove 2 formed on one side of the terminal block body 1, the groove 2 abutting against one side of a sealing ring 3, thereby improving the sealing performance and enhancing the waterproof effect by adding the sealing ring 3, the other side of the sealing ring 3 being fixedly connected to one side of a waterproof cover 4, a transparent cover plate 5 being fixedly installed on the other side of the waterproof cover 4, and anti-slip support blocks 21 being fixedly connected to the middle of both side walls of the terminal block body 1, the upper and lower surfaces of the anti-slip support blocks 21 having anti-slip textures, and the transparent cover plate 5 being used for easy access. Upon inspection of the wiring slot of the terminal block body 1, mounting plates 6 are fixedly connected to both sides of the waterproof cover 4. The mounting plates 6 are slidably connected to the anti-slip support blocks 21. While supporting the mounting plates 6, the anti-slip support blocks 21 can increase the surface friction between them, thereby preventing relative movement between the mounting plates 6 and the anti-slip support blocks 21. A limit plate 7 is fixedly installed on one side of the mounting plate 6. A U-shaped rod 8 is slidably sleeved inside the limit plate 7. One end of the U-shaped rod 8 is slidably inserted into the mounting plate 6. The limit plate 7 is fixedly connected to one end of the spring 9. The other end of the spring 9 is fixedly connected to the limit piece 10. The limit piece 10 is fixedly sleeved on the U-shaped rod 8.

[0024] In use, first, pull the symmetrically arranged U-shaped rods 8 backwards, causing them to slide under the limit plate 7. This drives the limit plate 10 to move in the direction that compresses the spring 9. Then, the groove 2 and the sealing ring 3 are inserted into each other, initially achieving the waterproof function. One side of the waterproof cover 4 abuts against the side of the terminal body 1 near the wiring groove. At the same time, the mounting plate 6 slides to the upper and lower sides of the anti-slip support block 21. The mounting plate 6 is arranged on the two side walls of the terminal body 1. Then, release the U-shaped rods 8. Under the reverse elastic force of the spring 9, the U-shaped rods 8 move in the opposite direction, causing one end of the U-shaped rods 8 to insert into the mounting plate 6. This allows the U-shaped plate 8 and the spring 9 to interact. Under the pressure of the force and the anti-slip support of the anti-slip support block 21, the mounting plate 6 is fixed and limited, thereby fixing the waterproof cover 4 to one side of the terminal body 1. The waterproof cover 4 and the sealing ring 3 further realize the waterproof function, thus preventing water from entering the inside of the terminal when the wiring port of the terminal body 1 is exposed to a humid environment or splashed with water, causing serious electrical faults and damaging the entire circuit system. In addition, when wiring, simply pass the wire through the transparent cover 5 and insert it into the wiring groove, and finally tighten the screw. The transparent cover 5 serves both as a waterproof function and as a means of facilitating wiring operations.

[0025] Example 2: Based on Example 1, the mounting plate 6 has two sets of four plates arranged symmetrically about the central plane of the waterproof cover 4. A limiting hole 11 is formed on one side surface of the mounting plate 6, and the limiting hole 11 is slidably inserted into one end of the U-shaped rod 8. Four mounting plates 6 are provided and fixedly installed on the side wall of the waterproof cover 4. The limiting hole 11 on the upper surface of the mounting plate 6 facilitates the insertion of the U-shaped rod 8. A limiting plate 7 is fixedly connected to both sides of the terminal body 1. A sliding hole 12 is formed on the surface of the limiting plate 7, and the sliding holes 12 are slidably connected between the U-shaped rods 8. A ventilation hole 13 is formed on the upper surface of the waterproof cover 4. The ventilation holes 13 increase ventilation inside and outside the waterproof cover 4, thus preventing overheating and potential danger. The ventilation holes 13 are arranged in a linear array. The limiting plate 7 limits the U-shaped rod 8 through the sliding holes 12. A drying box 14 is provided on the upper side of the ventilation holes 13, and a dustproof mesh plate 15 is provided on the lower side of the ventilation holes 13. The drying box 14 and the dustproof mesh plate 15 are fixedly connected to the waterproof cover 4 by small bolts. The fixed connection between the drying box 14 and the dustproof mesh plate 15 and the waterproof cover 4 by small bolts facilitates replacement after long-term use, thereby ensuring the effectiveness of the entire device.

[0026] When the U-shaped rod 8 slides into the mounting plate 7, it is limited by the sliding hole 12 on the limiting plate 7, thus ensuring the stability of the movement of the U-shaped rod 8. One end of the U-shaped rod 8 is adapted to the limiting hole 11 on the surface of the mounting plate 6, so that the mounting plate 6 is limited and fixed by the insertion of the U-shaped rod 8 through the limiting hole 11. When it is necessary to disassemble the waterproof cover 4, it is only necessary to pull the symmetrically arranged U-shaped rods 8 in the opposite direction to release the limitation of the U-shaped rod 8 on the mounting plate 6, thus facilitating subsequent maintenance operations. Several ventilation holes 13 are arranged in a linear array on the upper surface of the waterproof cover 4. The ventilation holes 13 are designed to ensure the airflow inside and outside the waterproof cover 4, thereby... To prevent overheating and affecting the normal operation of electronic components, a drying box 14 is installed above the ventilation hole 13. The drying box 14 is filled with drying particles to absorb moisture in the circulating air, thereby preventing the inside of the waterproof cover 4 from becoming damp and further achieving waterproof function. A dustproof mesh plate 15 is fixedly installed on the lower side of the drying box 14 to filter dust in the flowing air, thereby preventing external impurities from entering the inside of the terminal body 1 and affecting the service life of electronic components. The drying box 14 and the dustproof mesh plate 15 are both fixedly installed on the waterproof cover 4 with small bolts, which facilitates later replacement and ensures the effectiveness of use.

[0027] Example 3: Based on Example 2, the waterproof cover 4 is fixedly connected to the transparent cover plate 5 on one side by large bolts. The transparent cover plate 5 has a positioning hole 16 on the side away from the terminal body 1. The positioning holes 16 are arranged in a linear array on one side of the transparent cover plate 5. The waterproof cover 4 and the transparent cover plate 5 are installed by large bolts, which facilitates subsequent disassembly and maintenance. The positioning hole 16 limits and fixes the positioning sleeve 17. The positioning hole 16 is fixedly connected to one end of the positioning sleeve 17. The outer ring surface of the other end of the positioning sleeve 17 is threaded with a threaded sleeve 18. The inner ring surface of the other end of the positioning sleeve 17 is slidably fitted with an elastic clip 19. The end of the elastic clip 19 has four branches. The end of the elastic clip 19 with four branches is fixedly connected to a rubber block 20.

[0028] After the waterproof cover 4 is installed, when wiring is required, first pass the wire through the elastic clip 19 and insert it into the wiring slot of the terminal body 1 through the transparent cover 5. Then, tighten the screw on the top of the terminal body 1 to fix the wire. Then, twist the threaded connection sleeve 18 at one end of the positioning sleeve 17 to move the sleeve 18 closer to the terminal body 1. The sleeve 18 will press the elastic clip 19 into the positioning sleeve 17. Then, the four branches of the elastic clip 19 will continuously contract, which will cause the rubber block 20 to clamp the wire. While tightening the wire, it also increases the sealing between the wire and the rubber block 20, preventing moisture from entering the interior of the terminal body 1 along the wire. Once moisture enters, it may cause short circuits, reduced insulation performance, or even serious electrical faults, thereby damaging the entire circuit system and further reducing the service life and reliability of the terminal.
