Description
Technical Field
[0001] This utility model relates to the field of terminal block connection technology, specifically a terminal block connection structure for wire connection. Background Technology
[0002] In electrical equipment and circuit systems, terminal blocks are key components for realizing wire connections. The performance of their connection structure directly affects the stability and reliability of the electrical system. Currently, traditional terminal and cable connection structures have many problems in practical applications. On the one hand, during equipment maintenance, existing connection structures often require multiple tools and complex disassembly steps to separate cables from terminals, making rapid disconnection impossible. This operation not only consumes a lot of time and manpower, seriously affecting maintenance progress, but may also damage terminals and cables due to frequent disassembly, reducing their service life. On the other hand, when connecting wires are disconnected during maintenance, they are usually placed directly near the terminals, exposing the conductive core inside the connecting wires. The exposed conductive core is highly susceptible to electric shock and may also cause short circuits due to accidental contact, posing significant safety hazards and seriously threatening the personal safety of operators and the normal operation of electrical equipment. Utility Model Content
[0003] The purpose of this invention is to provide a terminal block connection structure for wire connection, so as to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a terminal block connection structure for wire connection, comprising a terminal and a conductive plate, wherein a cavity is formed inside the terminal, and a conductive plate is fixed inside the cavity; slotted rods are fixed inside both sides of the terminal, and a cavity is formed inside the slotted rod; a support block is slidably connected inside the cavity; a through hole is opened at the center of the support block, and a shell is fixed inside the through hole; a spring is sleeved on the outer wall of the shell, and one side of the spring is connected to the support block, and the other side is connected to the inner wall of the slotted rod; a conductive rod is fixed inside the shell; a transmission component is provided on the side of the support block away from the spring; and a fixing component is provided on the side wall.
[0005] Preferably, the transmission component includes a slider, which is fixed to the side of the support block away from the spring. Support plates are fixed to both the top and bottom ends of the slider. A threaded plate is rotatably connected to the outer wall of the groove rod, and the threaded plate corresponds to the support plate.
[0006] Preferably, the support plate is arc-shaped, and the outer wall of the arc is threaded to engage with the threaded inner wall of the threaded plate.
[0007] Preferably, the guide rod extends through a through hole in the support block into the interior of the slider.
[0008] Preferably, the fixing component includes a limiting block, which is slidably connected to both sides of the inner side of the groove rod. A first inclined block is fixed to the inner side of the limiting block, and a second inclined block is attached to the inclined side of the first inclined block. A connecting rod is fixed to the outer side of the second inclined block, and the side of the connecting rod away from the second inclined block is connected to the slider.
[0009] Preferably, the inner side of the first inclined block is machined with a rubber strip to increase friction when the cable is held in place.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By setting up a transmission component, pulling the support plate will cause the slider and support block to move outward, separating the transmission rod from the transmission plate and making room for cable connection. After the cable is connected, rotating the threaded plate in the opposite direction will use the spring reaction force to push the transmission rod back to its original position and fit against the transmission plate, achieving a quick connection without the need for complicated tools, greatly improving wiring efficiency and reducing the difficulty and time cost of manual operation. The conductive rod is installed in the housing with a tight fit, and its diameter is adapted to the internal space of the housing. At the same time, the spring provides inward tension to the housing, ensuring that the conductive rod and the conductive plate are always in close contact, effectively reducing contact resistance, ensuring the stability and reliability of current conduction, and reducing the risk of circuit failure due to poor contact. The first inclined block, the second inclined block, and the limiting block in the fixing component cooperate with each other. When the slider moves outward, the second inclined block moves through the connecting rod, converting the lateral force into an inward force, so that the first inclined block firmly clamps the cable. The rubber strip on the inner side of the first inclined block further increases the friction, preventing the cable from loosening or falling off, and ensuring the stability of the connection structure during use. The through-hole inside the support block fits tightly with the outer shell, and the diameter of the conductive rod is compatible with the outer shell. This design allows the terminal block connection structure to be compatible with various cable specifications, making it widely applicable. At the same time, the grooved rod provides a smooth and stable environment for the sliding of the support block, ensuring the reliability of the structure and improving the product's versatility. During equipment maintenance, simply pull the support plate to separate the transmission rod from the transmission plate, and fix the support plate with the threaded plate to quickly disconnect the terminal from the cable connection. This eliminates the need to remove the entire terminal block or perform complex operations, making it convenient to inspect and repair the equipment or cables, shortening maintenance time, and improving equipment maintenance efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0014] Please see Figure 1-4 This utility model provides a terminal block connection structure for wire connection: a terminal block connection structure for wire connection includes a terminal 1 and a conductive plate 2. The terminal 1 has an internal cavity, and the conductive plate 2 is fixed inside the cavity. Slotted rods 3 are fixed inside both sides of the terminal 1. The internal cavity of the slotted rod 3 is cylindrical, providing a smooth and stable environment for the sliding of the support block 4. The internal cavity of the slotted rod 3 has a slidably connected support block 4. The through hole inside the support block 4 is circular, and its diameter fits tightly with the outer shell 5, ensuring that the outer shell 5 is within the support block. 4. The support block 4 is firmly fixed inside. A through hole is opened in the center of the support block 4, and a shell 5 is fixed inside the through hole. A spring 6 is sleeved on the outer wall of the shell 5. One side of the spring 6 is connected to the support block 4, and the other side is connected to the inner wall of the groove rod 3. The spring 6 is used to provide an inward pulling force to the shell 5. A conduction rod 7 is fixed inside the shell 5. The conduction rod 7 is cylindrical in shape, and its diameter is adapted to the internal space of the shell 5. It is installed in the shell 5 in a tight fit manner to ensure the stability of current conduction. A transmission component is provided on the side of the support block 4 away from the spring 6, and a fixing component is provided on the side wall.
[0015] The transmission component includes a slider 8, which is fixed on the side of the support block 4 away from the spring 6. When the slider 8 is pulled outward, the spring 6 can be stretched through the support block 4. The top and bottom ends of the slider 8 are fixed with support plates 9. When the support plates 9 are pulled outward, they can engage with the threaded plate 14 to fix the slider 8. The outer wall of the groove rod 3 is rotatably connected to the threaded plate 14, and the threaded plate 14 corresponds to the support plate 9. The support plate 9 is arc-shaped, and the outer wall of the arc is threaded to engage with the threaded inner wall of the threaded plate 14. The transmission rod 7 extends into the interior of the slider 8 through the through hole of the support block 4.
[0016] The fixing component includes a limiting block 10, which is slidably connected to both sides of the inside of the groove rod 3. The limiting block 10 is used to limit the movement of the first inclined block 11 inward. The first inclined block 11 is fixed to the inside of the limiting block 10. When the first inclined block 11 moves inward, it can clamp and fix the cable. The inclined side of the first inclined block 11 is attached to the second inclined block 12. The second inclined block 12 is attached to the inclined side of the first inclined block 11, and the force of lateral movement is transmitted to the second inclined block 12. The second inclined block 12 converts the lateral force into the force of inward movement to hold the cable. The outer side of the second inclined block 12 is fixed to the connecting rod 13, and the side of the connecting rod 13 away from the second inclined block 12 is connected to the slider 8. The inner side of the first inclined block 11 is machined with a rubber strip to increase the friction when holding the cable.
[0017] Working principle: When a terminal block connection structure for wire connection is first used, and a cable needs to be connected to terminal 1, the user pulls the support plate 9 outward. During this pulling, the slider 8 drives the support block 4 to pull outward simultaneously. The outward movement of the support block 4 stretches the spring 6. During this stretching process, the outer shell 5 causes the conductive rod 7 to separate from the conductive plate 2. Then, when the support plate 9 moves outward and comes into contact with the threaded plate 14, the threaded plate 14 rotates, pulling the support plate 9 outward. The user then strips one end of the cable and inserts it into the slotted rod 3. When the cable is inserted into the slotted rod 3... The stripped cable is inserted into the slider 8 and fits against the conductor rod 7. Then, the user rotates the threaded plate 14 in the opposite direction. When the threaded plate 14 rotates in the opposite direction, the support plate 9 moves inward and separates from the threaded plate 14. After the threaded plate 14 separates from the support plate 9, the reaction force of the spring 6 drives the outer shell 5 to move inward through the support block 4. Then, the outer shell 5 drives the conductor rod 7 to move inward and fit against the conductor plate 2. When it is necessary to quickly disconnect the terminal from the cable during equipment maintenance, the user only needs to pull the support plate 9 outward to separate the conductor rod 7 from the conductor plate 2. After the support plate 9 is connected to the threaded plate 14, the equipment or cable can be maintained.
[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
