Description

Technical Field

[0001] This utility model relates to the field of cable connector technology, specifically to an adjustable cable connector structure. Background Technology

[0002] Cold shrink cable connectors are cable accessories made of elastic materials, vulcanized in the factory, and then expanded in diameter and lined with plastic spiral supports. During on-site installation, the cable connector is placed on the treated cable end or intermediate joint, and the internal supporting plastic spiral strip is pulled out. The cable connector will elastically shrink back at room temperature, wrapping the cable end or intermediate joint. Compared with heat shrink cable accessories, cold shrink cables do not require heating, and after installation, moving or bending them will not cause the risk of the internal layers of the accessory separating, unlike heat shrink cable accessories.

[0003] The internal support of the cold-shrink cable is made of a plastic spiral. In the process of using the existing technology, the inventor found that the plastic support inside the cold-shrink cable has a large number of spirals. When removing the spiral plastic support, it is necessary to disassemble and remove the support one spiral at a time. The operation is cumbersome, and the plastic support that is disassembled and removed one spiral at a time is easy to scratch the hands of the workers, which is very inconvenient. Utility Model Content

[0004] Based on the above description, this utility model provides an adjustable cable connector structure to solve the problem that the existing cold-shrink cable has a large number of spiral plastic support coils inside, and when the spiral plastic support is pulled out, it is necessary to disassemble and pull out the support coil by coil, which is cumbersome and can easily scratch the hands of the workers.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable cable joint structure includes a cold shrink joint. The inner side of the cold shrink joint is equipped with a first support part and a second support part that are distributed in a ring at equal intervals. The first support part and the second support part intersect each other and form a sliding connection. The first support part and the second support part extend toward both ends of the cold shrink joint, respectively.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, both the first support portion and the second support portion are arc-shaped, and the outer arc surface fits the inner side of the cold shrink joint. The axes of the first support portion and the second support portion coincide with the axis of the cold shrink joint.

[0008] Furthermore, the first support portions are distributed in a ring at equal intervals with the axis of the cold shrink joint as the center, and the second support portions are inserted between two adjacent first support portions.

[0009] Furthermore, the ends of the first support portion and the second support portion that are far apart from each other extend to the outside of the cold shrink joint and are integrally formed with curved paddles. The curved paddles are bent toward the outside of the cold shrink joint, and the other ends of the first support portion and the second support portion are flush with the two ends of the cold shrink joint.

[0010] Furthermore, the first support portion has grooves on both sides, and the end of the groove away from the curved paddle passes through the first support portion. The grooves are symmetrically distributed with the center of the first support portion as the origin.

[0011] Furthermore, the second support portion has integrally formed sliders on both sides that are slidably connected in the groove. The sliders are arranged at equal intervals and are symmetrically distributed with the center of the second support portion as the origin.

[0012] Furthermore, the first support portion and the second support portion are both arranged in a wavy shape on the side that fits against the inner wall of the cold shrink joint.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This invention replaces the traditional spiral plastic support structure by setting up a first support part and a second support part that are crisscrossed and slidably connected. This simplifies the disassembly process of the support components during installation. The first support part and the second support part can be pulled out from both ends of the cold shrink joint, eliminating the need to disassemble the spiral support piece by turn. This significantly improves operational efficiency and avoids the risk of the plastic spiral support piece scratching the workers' hands during disassembly, thus enhancing the safety and convenience of the installation process.

[0015] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0017] Please see Figure 1-6 The present invention discloses an adjustable cable connector structure, including a cold shrink connector 1. The inner side of the cold shrink connector 1 is provided with a first support part 2 and a second support part 4 that are distributed in a ring at equal intervals. The first support part 2 and the second support part 4 intersect each other and form a sliding connection. The first support part 2 and the second support part 4 extend toward both ends of the cold shrink connector 1, respectively.

[0018] Please see Figure 1 Both the first support part 2 and the second support part 4 are arc-shaped, and their outer arc surfaces are in contact with the inner side of the cold shrink connector 1. The axes of the first support part 2 and the second support part 4 coincide with the axis of the cold shrink connector 1. The first support parts 2 are distributed in a ring at equal intervals with the axis of the cold shrink connector 1 as the center. The second support part 4 is inserted between two adjacent first support parts 2. The first support parts 2 and the second support parts 4 adopt an arc-shaped design, which can form a complete cylindrical shape when they are inserted and combined. The outer arc surface is in contact with the inner side of the cold shrink connector 1 to ensure support stability. The cylindrical structure formed by the first support parts 2 and the second support parts 4 can ensure that the cold shrink connector 1 is subjected to uniform force, avoid irregular deformation caused by uneven force on the cold shrink connector 1, and ensure the stability of the cold shrink connector 1 in the expanded state.

[0019] Please see Figure 1 The first support part 2 and the second support part 4 extend to the outside of the cold shrink joint 1 at their respective ends and are integrally formed with a curved lever 6. The curved lever 6 bends toward the outside of the cold shrink joint 1. The other ends of the first support part 2 and the second support part 4 are flush with the two ends of the cold shrink joint 1. The curved lever 6 is provided at the outside of the cold shrink joint 1 at one end of the first support part 2 and the second support part 4, which makes it easy for the operator to quickly apply force to pull the support part and realize one-time extraction, reduce disassembly steps, improve installation efficiency, and avoid the inconvenience caused by pulling the traditional spiral support one turn at a time.

[0020] Please see Figure 3 The first support part 2 has grooves 3 on both sides. The end of the groove 3 away from the curved lever 6 passes through the first support part 2. The grooves 3 are symmetrically distributed with the center of the first support part 2 as the origin. The second support part 4 has sliders 5 integrally formed on both sides and slidably connected in the grooves 3. The sliders 5 are equidistantly arranged and symmetrically distributed with the center of the second support part 4 as the origin. The grooves 3 allow the sliders 5 of the second support part 4 to slide smoothly, ensuring that the support part will not get stuck when it is pulled out, improving the smoothness and reliability of the operation. At the same time, the grooves 3 pass through the end away from the curved lever 6, allowing the sliders 5 to slide out and detach from the grooves 3. The first support part 2 and the second support part 4 can slide and disassemble in a direction away from each other through the sliders 5 and the grooves 3, and be taken out from the cold shrink joint 1.

[0021] Please see Figure 1 The first support part 2 and the second support part 4 are both arranged in a wave-like shape on the side that fits against the inner wall of the cold shrink connector 1. The wave-like design of the first support part 2 and the second support part 4 on the side that fits against the inner wall of the cold shrink connector 1 reduces the friction of the contact surface. The wave-like side of the first support part 2 and the second support part 4 makes linear contact with the inside of the cold shrink connector 1. While ensuring uniform support for the cold shrink connector 1, it is convenient for the operator to apply force to pull the first support part 2 and the second support part 4 apart and pull them out of the cold shrink connector 1.
