[0031] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0032] In order to solve the problem of circuit and signal transmission interruption caused by unstable fixation of terminals and connectors in the prior art, a multifunctional fixed wire clamp is provided, such as Figure 1 As shown, the connector comprises a plastic body 1, terminals 2, and a wire clamp 3. The plastic body 1 has three slots 8 arranged in parallel. Terminals 2 are inserted into slots 8 on either side of the plastic body 1. Wires are secured to the terminals 2. The upper ends of the wire clamps 3 are snapped onto the plastic body 1, while the lower ends of the wire clamps 3 are also inserted into slots 8 on either side of the plastic body 1. The blocking members 6 on the surface of the wire clamps 3 abut against the slots 8 in the middle without terminals 2, forming a connector with the wire clamps 3.

[0033] like Figure 2 As shown, a limiting member 11 is provided on the terminal 2, and a limiting groove 12 is provided in the slot 8 of the plastic body 1. When the terminal 2 is inserted into place, the limiting member 11 abuts against the limiting groove 12. When the terminal 2 is installed in the plastic body 1, the limiting member on the terminal 2 is squeezed and fits against the terminal 2, pushing the terminal 2 so that the limiting member on the terminal 2 reaches the position of the limiting groove 12, causing the limiting member on the terminal 2 to rebound and abut against the limiting groove 12, thereby fixing the terminal 2 in the plastic body 1.

[0034] like Figure 3 As shown, the upper end of the wire clamp 3 is provided with a first fixed end 4, and the first fixed end 4 is provided with a back-off buckle 9. The upper end surface of the plastic body 1 is provided with a back-off groove 10. The back-off buckle 9 cooperates with the back-off groove 10 and is engaged in the back-off groove 10. The engagement of the back-off buckle 9 with the back-off groove 10 is performed internally, preventing the back-off buckle 9 from being unlocked by external forces and preventing it from falling off the connector.

[0035] The lower end of the wire clamp 3 is provided with two second fixed ends 5, and the positions of the two second fixed ends 5 correspond to the positions of the slots 8 on both sides of the plastic body 1. When in use, the two second fixed ends 5 at the lower end of the wire clamp 3 are respectively inserted into the slots 8 on both sides of the plastic body 1, and the first fixed end 4 at the upper end of the wire clamp 3 is inserted into the upper surface of the plastic body 1, as shown in FIG. Figure 4 As shown, the clamp 3 is fixed to the plastic body 1 until the retaining buckle 9 on the first fixed end 4 engages with the retaining groove 10. At this time, the wire clamp 3 is fixed to the plastic body 1. At the same time, push blocks 7 are symmetrically provided at the front end of the second fixed end 5. When the wire clamp 3 is gradually pushed into the plastic body 1, if the terminal 2 is not properly inserted, the push blocks 7 on the clamp 3 abut against the side of the terminal 2, pushing the terminal 2 into place within the plastic body 1.

[0036] When the terminal 2 is not installed in place in the plastic body 1, the wire clamp 3 is pushed so that the pushing block 7 on it pushes the terminal 2 so that the terminal 2 is installed in place. The pushing block 7 plays a protective role, fixing the terminal 2 in the plastic body 1 to prevent the terminal 2 from falling off due to external force.

[0037] When the wire clamp 3 is inserted into the plastic body 1, the blocking portion 6 on the wire clamp 3 abuts against the slot 8 where there is no terminal 2. If the terminal 2 is installed incorrectly, the wire clamp 3 cannot be installed on the plastic body 1 due to the blocking portion 6. This ensures that after the front-end operator installs the wire clamp 3, it can detect whether the terminal 2 is installed in the correct hole, which can prevent the connector from failing due to the incorrect hole, thus improving safety.

[0038] In order to facilitate the installation of the wire clamp 3 and the plastic body 1 , the connecting surfaces of the wire clamp 3 and the plastic body 1 are both configured as inclined surfaces to facilitate the insertion of the wire clamp 3 .

[0039] To strengthen the connection between the terminal 2 and the plastic body 1, a connection can be established between the wire clamp 3 and the terminal 2, thereby more firmly fixing the terminal 2 to the plastic body 1 and ensuring the stability of the terminal 2. A moving rod 13 and an elastic arc piece 14 are provided on the push block 7 at the second fixed end 5 of the wire clamp 3. The extension and contraction of the moving rod 13 within the push block 7 changes the angle of the elastic arc piece 14, so that the elastic arc piece 14 can clamp the spring piece 15 on the terminal 2, thereby establishing the connection between the terminal 2 and the plastic body 1.

[0040] like Figure 5As shown, the long side of the push block 7 is positioned on the second fixed end 5. A chute 16 is formed on the push block 7. The push block 7 has a trapezoidal cross-section, and the shape of the chute 16 matches that of the push block 7. A movable rod 13 is positioned between the two push blocks 7. The movable rod 13 is shaped like a "[" and has two side arms that slide and retract on the push blocks 7 on either side. The main arm of the movable rod 13 slides back and forth between the two push blocks 7. A stopper is provided at the front end of the chute 16 to prevent the two side arms of the movable rod 13 from slipping out of the chute 16 when sliding and retracting on the push blocks 7 on either side.

[0041] As the movable rod 13 slides from front to back between the push blocks 7, the width of the main rod of the movable rod 13 gradually decreases. A downwardly curved elastic piece 14 is sleeved on the movable rod 13. This naturally curved shape completely surrounds the spring piece 15 of the terminal 2. As the movable rod 13 slides from front to back between the push blocks 7, the angle of the elastic piece 14 gradually decreases.

[0042] When the second fixed end 5 of the wire clamp 3 extends into the plastic body 1 and the support rod of the movable rod 13 on it completely abuts the front face of the terminal 2, the terminal 2 is pushed into the plastic body 1, thereby gradually being installed into place. The push block 7 and the support rod of the movable rod 13 can keep the second fixed end 5 always abutting against the terminal 2 and can ensure that the push block 7 is always located above the spring 15 of the terminal 2, facilitating the elastic arc 14 to squeeze and fix the spring 15.

[0043] The elastic arc piece 14 includes at least a first state, and in the first state, the terminal 2 is not fully installed in place, and the wire clamp 3 is inserted into the plastic body 1. Figure 6 As shown, at this point, the main rod of the movable rod 13 is located at the short edge of the push block 7, the supporting rod of the movable rod 13 is fully extended in the push block 7, and the elastic arc piece 14 is in a naturally expanded state. The wire clamp 3 is gradually pushed in. When the supporting rod abuts against the terminal 2, the elastic arc piece 14 surrounds the spring piece 15 of the terminal 2.

[0044] The elastic arc piece 14 also includes a second state, and in the second state, the terminal 2 and the wire clamp 3 are not installed in place, the support rod is against the terminal 2, and the support rod is gradually pushed into the slide groove 16 in the push block 7, as shown in FIG. Figure 7 As shown, until the support rod of movable rod 13 is fully inserted into push block 7 and the main rod of movable rod 13 approaches the long side of push block 7, elastic arc piece 14 is compressed and clamped onto spring piece 15 of terminal 2. Terminal 2 is fixed to wire clamp 3. Wire clamp 3 is further pushed to install terminal 2 on plastic body 1. Wire clamp 3 is fixed to plastic body 1. At this point, elastic arc piece 14 remains clamped onto spring piece 15 of terminal 2. A stable connection is established between terminal 2, wire clamp 3, and plastic body 1, ensuring stable installation of terminal 2.

[0045] The usage process of the embodiment of the present invention is as follows:

[0046] Terminal 2 is installed in the plastic body 1. The stopper on terminal 2 is squeezed and fits against terminal 2, pushing terminal 2 to move in the plastic body 1. When terminal 2 is not properly installed in the plastic body 1, the wire clamp 3 is pushed, causing the push block 7 on the clamp to push terminal 2, causing the stopper on terminal 2 to reach the position of the stop slot 12. The stopper then rebounds and abuts against the stop slot 12, thereby securing terminal 2 in the plastic body 1.

[0047] As the clamp 3 is gradually pushed into the plastic body 1 until the support rod rests against the terminal 2, the elastic arc 14 surrounds the spring 15 of the terminal 2. Continue pushing the clamp 3, and the support rod gradually enters the slide groove 16 in the push block 7 until the main rod of the movable rod 13 approaches the long side of the push block 7. The elastic arc 14 is compressed and clamped onto the spring 15 of the terminal 2. Push the clamp 3 again until both the clamp 3 and the terminal 2 are installed in the plastic body 1.

[0048] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
