Description

Technical Field

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

[0002] Terminal blocks are accessories used to achieve electrical connections. In industry, they fall under the category of connectors. They facilitate the connection and disconnection of wires, preventing wires from being soldered or tangled together, and making it easier for later maintenance, repair, and replacement.

[0003] The connection between terminals and wires is generally achieved by using mechanical pressure to cause plastic deformation between the terminal and the wire, forming an intermolecular bond. This method is suitable for multi-strand stranded wires or single-core wires. The clamping method is usually achieved by manually operating crimping pliers, and the connection strength depends on the pressure of the operator's hands. In order to improve the connection strength between the wire and the terminal, we have designed a terminal connection clamping mechanism that uses a pull-down impact compression method to compress the terminal, thereby improving the connection strength between the terminal and the wire and ensuring the connection effect. Utility Model Content

[0004] The purpose of this utility model is to provide a terminal block connection clamping mechanism, which has the advantages of using a pull-down impact compression method to compress the terminal block, thereby improving the connection strength between the terminal block and the wire and ensuring the connection effect, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A terminal block connection clamping mechanism includes an L-shaped fixing plate, on which a terminal block head is placed. A movable plate that can move up and down is provided on the front side of the inner cavity of the L-shaped fixing plate. A T-shaped plate is fixedly installed on the front side of the movable plate. A threaded post is provided through the T-shaped plate. A punching head located above the terminal block head is installed below the threaded post. An L-shaped plate is fixedly installed on the right side of the movable plate. A connector is fixedly installed on the inner side of the L-shaped plate. A shaft connector is fixedly installed on the front side of the inner cavity of the L-shaped fixing plate. A V-shaped plate is rotatably connected to the inner cavity of the shaft connector through a rotating shaft. A pull rod is installed on the V-shaped plate. A diagonal rod is rotatably connected to the middle of the V-shaped plate through a rotating shaft. The diagonal rod is rotatably connected to the connector. An elastic reset component is provided between the bottom of the L-shaped plate and the L-shaped fixing plate.

[0006] Preferably, the bottom of the inner side of the L-shaped fixing plate is provided with a limiting cavity for placing the wiring terminal head.

[0007] Preferably, the elastic reset assembly includes a fixed seat fixedly installed on the front side of the L-shaped fixed plate, a guide rod fixedly connected to the bottom of the L-shaped plate, the bottom of the guide rod extending through to the bottom of the fixed seat and slidably connected to the fixed seat, and a spring sleeved on the surface of the guide rod, the top and bottom of the spring contacting the L-shaped plate and the fixed seat respectively.

[0008] Preferably, the guide rod is threaded with an anti-loosening nut, the top of which abuts against the fixing seat.

[0009] Preferably, two adjusting nuts are installed on the threaded post, and the two adjusting nuts abut against the T-shaped plate respectively.

[0010] Preferably, a guide rail is fixedly installed on the front side of the inner cavity of the L-shaped fixing plate, and a sliding sleeve is slidably connected to the surface of the guide rail. The front side of the sliding sleeve is fixedly installed with the movable plate.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model inserts a wire into a terminal head and places the terminal head in the inner cavity of a limiting cavity. Then, it quickly pulls down a pull rod. Through the cooperation of a V-shaped plate and a diagonal rod, it drives an L-shaped plate and a movable plate to move downward. This causes the threaded column and the punching head to move downward and impact and squeeze the terminal head inside the limiting cavity. The terminal head deforms and connects firmly with the wire. This achieves the purpose of using a pull-down impact and squeezing method to squeeze the terminal head, thereby improving the connection strength between the terminal head and the wire and ensuring the connection effect.

[0013] 2. This utility model uses the cooperation of guide rail and sliding sleeve. During the up and down movement of the movable plate, the sliding sleeve will slide up and down on the surface of the guide rail, which provides guidance and limit for the movement of the movable plate, improves the stability of the up and down movement of the movable plate, and ensures the accuracy of the impact and extrusion position of the punch head.

[0014] 3. By adjusting the setting of the nuts, the position of the threaded post on the T-shaped plate can be adjusted by operating the two adjusting nuts, thereby adjusting the height of the punch head. The height of the punch head can be adjusted according to the user's usage habits. Attached Figure Description

[0022] In the following description, embodiments of the terminal connection clamping mechanism of this utility model will be described with reference to the accompanying drawings.

[0023] Figure 1-4This invention illustrates a terminal block connection clamping mechanism according to an embodiment of the present invention. It includes an L-shaped fixing plate 1, on which a terminal block head 2 is placed. A limiting cavity 14 for placing the terminal block head 2 is provided at the bottom inner side of the L-shaped fixing plate 1. A movable plate 3, which can move up and down, is provided on the front side of the inner cavity of the L-shaped fixing plate 1. A T-shaped plate 4 is fixedly installed on the front side of the movable plate 3. A threaded post 5 is passed through the T-shaped plate 4, and two adjusting nuts 15 are installed on the threaded post 5. The two adjusting nuts 15 respectively abut against the T-shaped plate 4. By adjusting the nuts 15, the two terminals can be connected and clamped. The adjusting nut 15 can adjust the position of the threaded post 5 on the T-shaped plate 4, thereby adjusting the height of the punch head 6. The height of the punch head 6 can be adjusted according to the user's habits. The punch head 6 is installed below the threaded post 5 and above the terminal head 2. A guide rail 16 is fixedly installed on the front side of the inner cavity of the L-shaped fixing plate 1. A sliding sleeve 17 is slidably connected to the surface of the guide rail 16. The front side of the sliding sleeve 17 is fixedly installed to the movable plate 3. Through the cooperation of the guide rail 16 and the sliding sleeve 17, the sliding sleeve 17 will slide up and down on the surface of the guide rail 16 during the up and down movement of the movable plate 3. The movement of the movable plate 3 provides guidance and limitation, improving the stability of the up-and-down movement of the movable plate 3 and ensuring the accuracy of the impact and extrusion position of the stamping head 6. An L-shaped plate 7 is fixedly installed on the right side of the movable plate 3, and a connector 8 is fixedly installed on the inner side of the L-shaped plate 7. A shaft connector 9 is fixedly installed on the front side of the inner cavity of the L-shaped fixed plate 1. A V-shaped plate 10 is rotatably connected to the inner cavity of the shaft connector 9 via a rotating shaft. A pull rod 11 is installed on the V-shaped plate 10. A diagonal rod 12 is rotatably connected to the middle of the V-shaped plate 10 via a rotating shaft. The diagonal rod 12 is rotatably connected to the connector 8. The bottom of the L-shaped plate 7 is connected to the L-shaped fixed plate 10. An elastic reset assembly 13 is provided between the fixed plates 1. The elastic reset assembly 13 includes a fixed seat 131 fixedly installed on the front side of the L-shaped fixed plate 1. A guide rod 132 is fixedly connected to the bottom of the L-shaped plate 7. The bottom of the guide rod 132 extends through to the bottom of the fixed seat 131 and is slidably connected to the fixed seat 131. A spring 133 is sleeved on the surface of the guide rod 132. The top and bottom of the spring 133 contact the L-shaped plate 7 and the fixed seat 131 respectively. An anti-loosening nut 134 is threadedly connected to the surface of the guide rod 132. The top of the anti-loosening nut 134 abuts against the fixed seat 131.

[0024] Working principle: When using this utility model, insert the wire into the terminal head 2, then place it in the inner cavity of the upper limit cavity 14 of the L-shaped fixing plate 1, hold the pull rod 11 and pull it down. The pull rod 11 drives the V-shaped plate 10 to rotate. The V-shaped plate 10 pushes the L-shaped plate 7 downward through the inclined rod 12 and the connector 8. The L-shaped plate 7 drives the threaded column 5 and the punch head 6 downward through the movable plate 3 and the T-shaped plate 4, so that the punch head 6 impacts and squeezes the terminal head 2, causing the terminal head 2 to deform and firmly connect with the wire. During the downward movement of the L-shaped plate 7, the guide rod 132 will slide on the fixed seat 131 and squeeze the spring 133. After the punching is completed, the restoring force of the spring 133 pushes the L-shaped plate 7 to reset, thereby causing the pull rod 11 to reset, which is convenient for the next pressing operation. The anti-loosening nut 134 can prevent the guide rod 132 from detaching from the fixed seat 131.

[0025] In summary, this terminal block clamping mechanism works by inserting a wire into the terminal block head 2 and placing the terminal block head 2 inside the limiting cavity 14. Then, the pull rod 11 is quickly pulled down. The V-shaped plate 10 and the inclined rod 12 work together to move the L-shaped plate 7 and the movable plate 3 downwards. This causes the threaded column 5 and the punch head 6 to move downwards, impacting and squeezing the terminal block head 2 inside the limiting cavity 14. The terminal block head 2 deforms and firmly connects with the wire. This achieves the goal of using a pull-down impact squeezing method to compress the terminal block, increasing the connection strength between the terminal block and the wire, and ensuring a good connection effect.
