Description

Technical Field

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

[0002] When connecting a terminal block to a terminal block, the screws on the terminal block secure the terminal block. Since the connection between the wire and the terminal block is generally a compression connection, the movement and pulling of the wire can easily cause the wire to break from the terminal block. Therefore, we have proposed a terminal locking structure that uses plastic fasteners to compress and fix the wire near the terminal block, ensuring that the connection between the terminal block and the wire will not move easily after the terminal block is connected, thus ensuring stability. Utility Model Content

[0003] The purpose of this utility model is to provide a terminal locking structure, which uses plastic fasteners to press and fix the wires near the terminal, ensuring that the connection position of the terminal and the wire will not easily move after the terminal is connected to the terminal block, thus ensuring stability and solving the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A terminal locking structure includes a support block fixedly installed below the wiring ports on both sides of the terminal block body. Terminal heads are installed on both sides of the terminal block body by screws. A wire body is installed on the terminal head. The wire body rests on the top of the support block. An elastic U-shaped strip is provided through the top of the support block. Two rectangular through holes are opened on the top of the support block for the elastic U-shaped strip to pass through. Multiple equally spaced protrusions are provided on both sides of the elastic U-shaped strip. The bottom sides of the support block are equipped with locking blocks that are adapted to the protrusions. The inner wall of the elastic U-shaped strip presses on the wire body.

[0005] Preferably, threaded holes are provided on both sides of the bottom of the support block, and a fastening screw that is threadedly connected to the threaded hole is provided through the block.

[0006] Preferably, the card block has a strip-shaped hole through which the fastening screw passes and moves.

[0007] Preferably, two symmetrical guide pins are fixedly connected to both sides of the bottom of the support block, and two strip holes that move on the surface of the guide pins are opened on the card block.

[0008] Preferably, the top of the support block has a limiting cavity for placing the wire body.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model involves installing a locking block below a support block, then connecting the terminal head to the terminal block body, with the wire body on the terminal head resting on the support block. Next, an elastic U-shaped strip is inserted into the inner cavity of two rectangular through holes until it is firmly pressed against the wire body. The locking block on the support block is then inserted between two protruding strips to lock the elastic U-shaped strip in place, thus confining the wire body to the top of the support block. This achieves the goal of using plastic fasteners to press and fix the wire near the terminal, ensuring that the connection between the terminal and the wire does not easily move after the terminal is connected to the terminal block, thus guaranteeing stability.

[0011] 2. This utility model utilizes the combined use of a threaded hole, a fastening screw, a first slotted hole, a guide pin, and a second slotted hole. When installing the clip, insert the fastening screw into the inner cavity of the first slotted hole on the clip and thread it into the inner cavity of the threaded hole to install the clip. Moreover, the clip can move on the surface of the two guide pins, and the first slotted hole on the clip can move on the surface of the fastening screw to adjust the inward distance of the clip, ensuring that the clip can be securely engaged with the gap between the two protruding strips.

[0012] 3. By setting up a limiting cavity, this utility model can ensure the stability of the wire body at the top of the support block. The wire body will not shift during the pressing process of the elastic U-shaped strip, thus improving the stability of the wire body after it is fixed. Attached Figure Description

[0020] In the following description, embodiments of the terminal locking structure of this utility model will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a terminal locking structure according to an embodiment of the present invention. It includes support blocks 2 fixedly installed below the connection ports on both sides of the terminal block body 1. Terminal heads 3 are screwed onto both sides of the terminal block body 1, and wire bodies 4 are mounted on the terminal heads 3. The wire bodies 4 rest on the top of the support blocks 2. An elastic U-shaped strip 5 is provided through the top of the support blocks 2. A limiting cavity 6 is provided on the top of the support blocks 2 for placing the wire bodies 4. The limiting cavity 6 ensures the stability of the wire bodies 4 on the top of the support blocks 2, preventing displacement of the wire bodies 4 during the pressing process of the elastic U-shaped strip 5, thus improving the stability of the wire bodies 4 after fixing. Two rectangular through holes 7 are provided on the top of the support blocks 2 for the elastic U-shaped strip 5 to pass through. Multiple equally spaced protrusions 8 are provided on both sides of the elastic U-shaped strip 5. Locking blocks 9 adapted to the protrusions 8 are installed on both sides of the bottom of the support blocks 2. Both sides of the bottom are provided with threaded holes 10. A fastening screw 11 is threaded through the block 9 and connected to the threaded hole 10. The block 9 is provided with a slotted hole 12 for the fastening screw 11 to pass through and move. Two symmetrical guide pins 13 are fixedly connected to both sides of the bottom of the support block 2. The block 9 is provided with two slotted holes 14 that move on the surface of the guide pins 13. By using the threaded hole 10, fastening screw 11, slotted hole 12, guide pin 13 and slotted hole 14 together, when installing the block 9, the fastening screw 11 is inserted into the inner cavity of the slotted hole 12 on the block 9 and threaded into the inner cavity of the threaded hole 10, the block 9 can be installed. Moreover, the block 9 can move on the surface of the two guide pins 13, and the slotted hole 12 on the block 9 can move on the surface of the fastening screw 11. Adjusting the inward distance of the block 9 ensures that the block 9 can be firmly engaged with the gap between the two protruding strips 8. The inner wall of the elastic U-shaped strip 5 presses on the wire body 4.

[0022] Working principle: When using this utility model, the terminal head 3 is installed on the terminal block body 1 by screws on the terminal block body 1. During this process, the wire body 4 on the terminal head 3 rests on the support block 2. The elastic U-shaped strip 5 is picked up and inserted into the inner cavity of the two rectangular through holes 7 on the support block 2. The protrusions 8 on the elastic U-shaped strip 5 come into contact with the locking block 9, causing the elastic U-shaped strip 5 to deform inward until the top of the inner cavity of the elastic U-shaped strip 5 is in contact with the wire body 4. At this time, the locking block 9 is locked in the gap between the two protrusions 8, which realizes the limiting of the elastic U-shaped strip 5 and prevents the elastic U-shaped strip 5 from moving upward. The surface of the wire body 4 on the terminal head 3 is near the limiting and locking of the elastic U-shaped strip 5 and the support block 2, ensuring a stable connection.

[0023] In summary, this terminal locking structure, by installing the locking block 9 below the support block 2, then connecting the terminal head 3 to the terminal block body 1, with the wire body 4 on the terminal head 3 resting on the support block 2, then inserting the elastic U-shaped strip 5 into the inner cavity of the two rectangular through holes 7 until the elastic U-shaped strip 5 is firmly pressed onto the wire body 4, and inserting the locking block 9 on the support block 2 between the two protruding strips 8 to lock the state of the elastic U-shaped strip 5, thus restricting the wire body 4 to the top of the support block 2, achieves the purpose of using plastic fasteners to press and fix the wire near the terminal, ensuring that the position of the terminal and the wire connection will not easily move after the terminal is connected to the terminal block, thus ensuring stability.
