[0033] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.
[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.
[0035] A cable is an electrical energy and signal transmission device, usually made of one or more mutually insulated conductors covered with an insulation layer and a protective layer. Its main function is to transmit electrical energy or electrical signals from one place to another, and it is an indispensable component of modern power systems and communication systems.
[0036] However, cables are often exposed to sunlight, high temperatures, and humidity, especially at the joints between interconnected cables. After prolonged use, this can lead to aging of the cable surface, affecting the cable's insulation performance and increasing the risk of cable damage.
[0037] To resolve the above technical issues, please refer to Figures 1 to 4 This application provides a conductor connection structure 100 for use in power cables. The conductor connection structure 100 may include: a fixing ring 110, a telescopic cylinder 120, a first clamp 130, a winding assembly, and a connecting rope 150.
[0038] Specifically, a fixing ring 110 is sleeved on the cable and fixedly connected to the cable. The fixing ring 110 includes a first end face and a second end face that are opposite to each other. A telescopic cylinder 120 is sleeved on the cable and is located on the side where the first end face of the fixing ring 110 is located. The telescopic cylinder 120 includes an inner cylinder 122 and an outer cylinder 121. The outer cylinder 121 is connected to the fixing ring 110. The inner cylinder 122 has a connecting ring 1221 at one end away from the fixing ring 110. A first clamp 130 is located on the side of the telescopic cylinder 120 away from the fixing ring 110 and is fixedly sleeved on the cable. A winding assembly is provided on the first clamp 130. The winding assembly includes a bracket and a winding rod 142. The winding rod 142 is rotatably connected to the bracket. One end of the connecting rope 150 is connected to the winding rod 142, and the other end is connected to the connecting ring 1221.
[0039] It should be noted that in the specific operation process, the fixing ring 110 and the first clamp 130 are fixed first, and then the connecting rope 150 is wound by rotating the winding rod 142, so that the connecting rope 150 pulls the connecting ring 1221, causing the telescopic cylinder 120 to extend. The telescopic cylinder 120 protects the cable, thereby reducing the time that the cable corresponding to the position of the telescopic cylinder 120 is exposed to sunlight, high temperature and humid environment, slowing down the aging of the cable surface and extending the service life of the cable.
[0040] It can be understood that multiple cylindrical structures can be provided between the inner cylinder 122 and the outer cylinder 121 of the telescopic cylinder 120 to extend the elongation length of the telescopic cylinder 120.
[0041] Furthermore, the fixing ring 110 is provided with an annular groove, the opening of which is located on the first end face. The outer cylinder 121 is connected to the bottom wall of the annular groove, and the telescopic cylinder 120 can be housed in the annular groove.
[0042] In this way, when the conductor connection structure 100 is not in use, the storage space for the retaining ring 110 and the telescopic cylinder 120 can be reduced.
[0043] Furthermore, the conductor connection structure 100 may also include a connecting spring 123, one end of which is connected to the bottom wall of the annular groove and the other end is connected to the outer cylinder 121. The connecting spring 123 always applies a pulling force toward the bottom wall of the annular groove to the outer cylinder 121.
[0044] In this way, when the winding rod 142 is reversed, the outer cylinder 121 will be housed in the annular groove under the action of the connecting spring 123. At the same time, the connection between the outer cylinder 121 and the bottom wall of the annular groove is achieved through the connecting spring 123.
[0045] The number of connecting springs 123 can be multiple, and the multiple connecting springs 123 are spaced apart in the circumferential direction of the outer cylinder 121.
[0046] This prevents the telescopic cylinder 120 from tilting during movement and ensures its stability during use.
[0047] In some embodiments of this application, a connecting plate 124 is provided on the second end face, and the conductor connection structure 100 further includes a second clamp 160, which fixes the connecting plate 124 to the cable.
[0048] Therefore, by setting the second clamp 160 and the connecting plate 124, the fixed connection between the fixing ring 110 and the cable is realized, thereby fixing the telescopic cylinder 120.
[0049] In some embodiments of this application, the bracket includes an L-shaped plate 1411, the free end of the long plate of the L-shaped plate 1411 is fixedly connected to the first clamp 130, and the winding rod 142 passes through the short plate of the L-shaped plate 1411 and is rotatably connected to the short plate of the L-shaped plate 1411.
[0050] It should be noted that by setting the L-shaped plate 1411, the winding rod 142 can be clamped on the first clamp 130, so that the winding rod 142 is located on the outside of the cable. In this way, interference between the connecting rope 150 and the cable can be avoided during the rotation of the winding rod 142.
[0051] When the long plate of the L-shaped plate 1411 is located between the winding rod 142 and the telescopic cylinder 120, a through hole for the connecting rope 150 to pass through is also required on the L-shaped plate 1411.
[0052] In some embodiments of this application, the conductor connection structure 100 further includes a first handle 143, which is located at one end of the winding rod.
[0053] In this way, by setting the first handle 143, the operator can be provided with a position to rotate the winding rod 142, reducing the difficulty of rotating the winding rod 142.
[0054] In some embodiments of this application, the bracket may further include an auxiliary plate 144 and a threaded post 145. The auxiliary plate 144 is connected to the short plate and is arranged perpendicular to the short plate. The auxiliary plate 144 is provided with a threaded hole, which is arranged opposite to the winding rod 142. The threaded post 145 is threadedly engaged with the threaded hole and can abut against the winding rod 142.
[0055] Therefore, by setting the auxiliary plate 144 and the threaded post 145, the winding rod 142 can be limited when it rotates to the target position, so as to avoid the winding rod 142 reversing and affecting the normal use of the conductor connection structure 100.
[0056] In some embodiments of this application, the conductor connection structure 100 further includes an anti-slip sleeve 180, which is fixedly sleeved on the cable and located between the first clamp 130 and the telescopic cylinder 120. Thus, by providing the anti-slip sleeve 180, the contact area of the operator's hands when handling the cable can be increased.
[0057] The outer wall of the cable is fixedly connected with multiple scale lines at equal intervals. These scale lines serve to remind workers of the cable's length when using it.
[0058] In some embodiments of this application, please refer to Figure 1 and Figure 5The conductor connection structure 100 may further include a clamping mechanism 170, which includes: a hollow ring 171, a semi-circular block 172, a pull rod 173 and abutment spring 174, a fixed short plate 175, a movable plate 176 and a threaded rod 177. The hollow ring 171 is sleeved on the cable; the semi-circular block 172 is located inside the hollow ring 171; the pull rod 173 passes through the hollow ring 171 and includes a first end and a second end, the first end being connected to the semi-circular block 172 via the abutment spring 174; the fixed short plate 175 is connected to the hollow ring 171 and has a first threaded hole; the movable plate 176 has a second threaded hole and is located outside the second end; the threaded rod 177 passes through the first threaded hole and the second threaded hole and is threadedly engaged with the first threaded hole and the second threaded hole.
[0059] In this way, the operator can hold the movable plate 176 with one hand to ensure that the movable plate 176 is opposite to the second end, and rotate the threaded rod 177 with the other hand so that the movable plate 176 presses the pull rod 173. The pull rod 173 compresses the spring and applies a pushing force to the semi-circular block 172, so that the semi-circular block 172 moves away from the pull rod 173, clamping the cable between the semi-circular block 172 and the inner wall of the hollow ring 171, thereby allowing the clamping mechanism 170 to be fixed at the cable interface.
[0060] It is understandable that the interface is more likely to be damaged, and the clamping mechanism 170 can be used to protect the cable interface.
[0061] Furthermore, the number of semicircular blocks 172, pull rods 173, abutment springs 174, fixed short plates 175, movable plates 176, and threaded rods 177 can all be two, with the cable clamped between the two semicircular blocks 172.
