[0014] Compared with the prior art, the present invention provides a power fitting connector for an elastic cable, which has the following beneficial effects: 1. By setting the fixing mechanism, the insertion mechanism can be limited. After the insertion mechanism completes the distance movement, the fixing mechanism can prevent it from moving again, thereby ensuring the stability of the installation of the power fitting connector after installation.

[0015] 2. By setting the clamping plate, when the rotating block is pushed, the hook part of the rotating block is used to ensure the smooth combination of the two without jamming. Moreover, when the rotating block and the clamping plate are successfully combined, the connection is stable and there is no shaking, thereby effectively preventing the cable from shifting.

[0016] 3. By setting the insertion mechanism, the limit can be quickly achieved after the cable is installed, which effectively avoids the problem of cable deviation during installation due to the long installation time, and ensures the accuracy and stability of the installation.

[0017] 4. By setting the limiting mechanism, the limiting mechanism can ensure that the sleeve can move freely. When the limiting mechanism is in the locked state, it will restrict the sleeve and make it unable to move. This design can produce a certain buffering effect when facing an elastic cable.

The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0022] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation" and other terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] Embodiment 1: Refer to Figures 1 - 5 , the present invention provides a technical solution: a power hardware connector for elastic cables, including a bent rod 1. There are two groups of fixed blocks 2 arranged on the outer wall of the bent rod 1. The inner walls of the two groups of fixed blocks 2 are both slidably connected to the outer wall of the bent rod 1. A sleeve 3 is fixedly connected to one side of the two groups of fixed blocks 2 close to each other. It also includes: Fixing mechanism 4, the fixing mechanism 4 includes two groups of moving plates 401. On the side of the two groups of moving plates 401 close to the bent rod 1, they are all slidably connected to the outer wall of the bent rod 1. On the side of the two groups of moving plates 401 away from the bent rod 1, two groups of first connecting rods 403 are arranged. On the side of the four groups of first connecting rods 403 close to the moving plate 401, they are all slidably connected to the moving plate 401. On the side of the four groups of first connecting rods 403 away from the moving plate 401, a pushing block is fixedly connected. On the side of the two groups of first connecting rods 403 on the left close to the moving plate 401, two second arc-shaped blocks 405 are fixedly connected. On the side of the two groups of second arc-shaped blocks 405 away from the moving plate 401, two first bent plates 407 are fixedly connected. By setting the rotating block 408, the hook of the rotating block 408 can restrict the groove of the clamping plate 406, so that the combination is more firm after combination, and there will be a certain gap after combination, thus enhancing a certain contraction performance. On the side of the two groups of first bent plates 407 away from the moving block, two groups of rotating blocks 408 are rotatably connected through a first rotating shaft. The first bent plate 407 is used to fix the position of the rotating block 408. On the side of the two groups of first connecting rods 403 on the right close to the moving plate 401, two first arc-shaped blocks 404 are fixedly connected. On the side of the two groups of first arc-shaped blocks 404 close to the rotating block 408, a clamping plate 406 is fixedly connected. By setting the clamping plate 406, it can prevent the left and right shaking after fixation, thus ensuring the stability of the fixing mechanism 4 after installation. The fixing mechanism 4 is provided in two groups and is symmetrically arranged with the middle of the bent rod 1 as the center. The clamping plate 406 is used to push the rotating block 408 to rotate at an angle.

[0024] The working principle of this embodiment is as follows: During the installation operation, the staff pushes the moving plate 401 to move it on the outer wall of the bent rod 1. While the moving plate 401 moves, it drives the first connecting rod 403 to move synchronously, and then pushes the pushing plate 402. During this process, the first connecting rod 403 also drives the first arc-shaped block 404 and the second arc-shaped block 405 to move synchronously. When the first arc-shaped block 404 and the second arc-shaped block 405 move, they drive the clamping plate 406 and the first bent plate 407 to move. At the same time, the first bent plate 407 drives the rotating block 408 to move. After the moving plate 401 completes its movement on the bent rod 1, the staff pushes the pushing plate 402 to push the moving plate 401 closer to the outer wall of the bent rod 1. When the moving plate 401 moves, it drives the first connecting rod 403 to move towards the outer wall of the bent rod 1, and then pushes the first arc-shaped block 404 and the second arc-shaped block 405 to move synchronously. This makes the first arc-shaped block 404 and the second arc-shaped block 405 push the clamping plate 406 and the first bent plate 407 closer to each other. When the clamping plate 406 moves, it pushes the rotating block 408 to rotate. Finally, the rotating block 408 is caught in the groove of the clamping plate 406 to complete the fixation.

[0025] Embodiment Two: Please refer to Figure 6On the basis of Embodiment 1, the present invention provides a technical solution: It further includes an insertion mechanism 5. The insertion mechanism 5 includes a first sliding block 501. The side of the first sliding block 501 close to the bent rod 1 is slidably connected to the outer wall of the bent rod 1. On the side of the first sliding block 501 away from the moving plate 401, two groups of positioning rods 502 are fixedly connected. The first sliding block 501 is used to push the positioning rods 502 to move. On the side of the two groups of positioning rods 502 away from the first sliding block 501, a rotating block 503 is rotatably connected through a second rotating shaft. On the side of the two groups of rotating blocks 503 away from the positioning rods 502, a spring 504 is fixedly connected. The spring 504 is used to slow down the driving force of the rotating block 503. On the side of the two groups of springs 504 away from the rotating blocks 503, a rectangular plate 506 is fixedly connected. By setting the spring 504, it can be ensured that on the side of the two rectangular plates 506 away from the spring 504, two groups of clamping plates 505 are fixedly connected. By setting the spring 504, it can be ensured that during the movement, due to the instability of the spring 504, the moving ring 507 will shake during the movement, so that when it comes into contact with the limiting mechanism 6, it can be better combined. On the side of the four groups of clamping plates 505 away from the rectangular plate 506, a moving ring 507 is fixedly connected. The insertion mechanism 5 is provided in two groups and is symmetrically arranged with the middle of the bent rod 1 as the center. The clamping plate 505 is used to prevent the moving ring 507 from tilting at an angle.

[0026] The working principle of this embodiment is as follows: When the moving plate 401 moves on the bent rod 1, it will synchronously drive the first sliding block 501 to slide on the bent rod 1. During the movement of the first sliding block 501, it will drive the positioning rods 502 to displace synchronously. When the positioning rods 502 move, they will push the rotating block 503, and the rotating block 503 will then push the spring 504. After the spring 504 is forced to move, it will push the rectangular plate 506. When the rectangular plate 506 moves, it will push the clamping plate 505. While the clamping plate 505 moves, it drives the moving ring 507, and finally realizes the overall movement of the insertion mechanism 5.

[0027] Embodiment 3: Please refer to Figures 7 - 8, based on the first and second embodiments, the present invention provides a technical solution: it further includes a limiting mechanism 6. The limiting mechanism 6 includes a second sliding block 601. The side of the first sliding block 601 close to the bent rod 1 is slidably connected to the outer wall of the bent rod 1. On the side of the second sliding block 601 away from the moving plate 401, two groups of second connecting rods 602 are fixedly connected. On the side of the two groups of second connecting rods 602 close to the fixed block 2, they are fixedly connected to the fixed block 2. On the side of the second sliding block 601 close to the fixed block 2, two groups of contact plates 603 are fixedly connected. The second sliding block 601 is used to drive the contact plates 603 to slide. On the inner walls of the two groups of contact plates 603, there are top plates 604. On the side of the two groups of top plates 604 close to the contact plates 603, they are fixedly connected to the inner walls of the contact plates 603. On the side of the two groups of top plates 604 away from the contact plates 603, elastic plates 608 are fixedly connected. On the side of the two groups of elastic plates 608 away from the top plates 604, return rods 609 are fixedly connected. The elastic plates 608 are used to pull the return rods 609 to incline. On the inner walls of the two groups of contact plates 603, there are fitting plates 605. On the front and back sides of the two groups of fitting plates 605, they are fixedly connected to the inner walls of the contact plates 603. On the side of the two groups of fitting plates 605 close to the elastic plates 608, two groups of third sliding blocks 607 are slidably connected. By setting the third sliding blocks 607, it can ensure that the elastic plates 608 have a certain space for rebounding when rebounding, avoiding component damage caused by the inability of the elastic plates 608 to rebound. On the side of the four groups of third sliding blocks 607 close to the elastic plates 608, support blocks 606 are fixedly connected. By setting the support blocks 606, it can ensure that when the elastic plates 608 rebound, the support blocks 606 restrict them, ensuring the inclination angle of the return rods 609, so that the insertion mechanism 5 can be better removed. The limiting mechanism 6 is provided in two groups and is symmetrically arranged with the middle of the bent rod 1 as the center. The support blocks 606 are used to prevent the elastic plates 608 from bending in the reverse direction.

[0028] The working principle of this embodiment is as follows: When the moving ring 507 moves a certain distance, it will come into contact with the resilient rod 609. Under the push of the moving ring 507, the resilient rod 609 begins to tilt at a small angle towards the side away from the insertion mechanism 5. The moving ring 507 continues to push, causing the resilient rod 609 to tilt further. When the resilient rod 609 tilts to a certain angle, since the moving ring 507 is still moving continuously, the resilient rod 609 will get stuck in the inner wall of the moving ring 507. During the tilting process of the resilient rod 609, it will drive the elastic plate 608 to bend, which helps the resilient rod 609 to obtain a better tilt angle. When the elastic plate 608 bends towards the side close to the insertion mechanism 5, it will come into contact with the supporting block 606. At this time, the supporting block 606 will restrict the elastic plate 608, and when the elastic plate 608 bends towards the supporting block 606 side, it will push the supporting block 606 to move slightly. When the supporting block 606 is moving, it will push the third sliding block 607 to slide on the fitting plate 605, so as to ensure that the elastic plate 608 has a moving space, but the elastic plate 608 can only bend slightly and cannot drive the resilient rod 609 to tilt synchronously, thus ensuring that the resilient rod 609 can work properly.
