Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a cable connector and a cable. Background Technology

[0002] Cables, as crucial carriers of power transmission and signal transmission, play a vital role in modern infrastructure construction and industrial production. In cable installation projects, due to the limitations of cable length and the complexity of the route, multiple cable segments often need to be connected to form a complete line. At this point, the cable joint becomes an indispensable key component. Its core function is to achieve a stable connection at the junction of cable segments, ensuring the electrical conductivity of the entire cable line. Simultaneously, the cable joint must provide reliable sealing protection, isolating the intrusion of the external environment (such as moisture and dust), and maintaining the required insulation strength at the connection point, thereby ensuring the long-term safe and stable operation of the cable line.

[0003] In existing technologies, some cable joints and their associated cable structures still have significant shortcomings in practical applications. On the one hand, in situations where cables need to be moved or dragged after installation, these cable joints often exhibit poor resistance to displacement, easily becoming loose, and in severe cases, even completely detaching. This not only interrupts the continuity of the line but also significantly affects the performance and reliability of the entire system, thus its practicality needs improvement. On the other hand, some existing cable joints, after being connected to the cable, do not have an ideal sealing effect at the connection interface, resulting in weak sealing points. This can allow external moisture or contaminants to penetrate the joint, easily causing a decline in insulation performance under the influence of an electric field, and even inducing a short circuit at the cable-joint connection, creating serious safety hazards. Therefore, this utility model proposes a cable joint and cable to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cable connector and cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable connector and a cable, comprising: a connector body, with symmetrical butt grooves at both ends of the connector body, a battery core matching the cable being installed through the middle of the inner side of the connector body, a rubber sleeve being fixedly fitted on the inner ring surface of the butt groove, a relatively movable clamping plate being provided on one side of the butt groove, the bottom of the clamping plate being arc-shaped and a rubber block being fixedly connected inside the arc surface, an anti-slip texture being provided on one side of the rubber block, and a driving component for driving the relative movement of the clamping plate being connected to the top of the clamping plate;

[0006] A limiting component for limiting the drive assembly is provided in the middle of the upper surface of the connector body.

[0007] Preferably, the drive assembly includes an H-shaped frame, with sliding pins fixedly fitted at both ends of the H-shaped frame, and a drive rod rotatably fitted in the middle of the H-shaped frame.

[0008] Preferably, two limiting plates are fixedly sleeved on the drive rod, and the upper and lower limiting plates are respectively attached to the upper and lower surfaces of the H-shaped frame, and guide plates are fixedly connected to both ends of the upper surface of the connector body.

[0009] Preferably, sliders are slidably connected to both ends of one side of the guide plate, a connecting block is fixedly connected to the top of the slider, an arc-shaped hole is opened on the surface of the connecting block, the bottom of the connecting block is fixedly connected to the clamping plate, and the arc-shaped hole is slidably connected to the sliding pin.

[0010] Preferably, an arc-shaped piece is fixedly connected to the bottom of the drive rod, and the limiting component includes a limiting platform. The lower surface of the limiting platform is fixedly connected to the middle of the upper surface of the connector body. The limiting platform is hollow, and an arc-shaped groove matching the arc-shaped piece is opened in the middle of the upper surface of the limiting platform.

[0011] Preferably, a limiting hole is provided at the end of the arc-shaped plate away from the drive rod, and stepped holes are provided on both sides of the upper surface of the limiting plate. The top of the stepped hole is fixedly connected to the top of the pin by a return spring, and the bottom of the stepped hole is slidably inserted into the bottom of the pin. The bottom of the pin passes through the stepped hole and is adapted to the limiting hole.

[0012] A cable including the cable connector described above.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By employing a bidirectional, driven arc-shaped clamping mechanism with a clamping plate, anti-slip textured rubber blocks, and a mechanical linkage locking system (H-frame, drive rod, and limit assembly), a multi-directional flexible clamping force is formed after cable insertion. When the drive assembly presses down, the clamping plate tightens synchronously along the outer ring of the cable. The arc-shaped surface and anti-slip texture of the rubber block significantly enhance the static friction with the cable. The limit assembly then locks the drive rod's rigid locking pin into the limit hole, creating a multi-layered anti-retraction mechanism. This design completely solves the problem of joint displacement, shaking, or even detachment caused by vibration or dragging during cable movement, ensuring long-term stable and reliable connection.

[0015] 2. By incorporating a mating groove with a built-in rubber sleeve at the cable insertion end, the elastic deformation of the groove achieves the first seal on the outer ring of the cable. Simultaneously, during the tightening process of the clamp, the rubber block tightly wraps around the cable surface, forming a radial pressure sealing layer that complements the first sealing structure. The combined effect isolates external moisture and dust from intrusion and eliminates microscopic gaps between the cable and the joint interface, significantly improving the overall sealing and insulation reliability of the connection. This effectively avoids the risk of short circuits caused by media infiltration, eliminating potential safety hazards at their source. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a cable connector and a cable, comprising: a connector body 1, with symmetrical mating grooves 2 at both ends of the connector body 1, facilitating the insertion of two cables from both sides through the mating grooves 2 on both sides of the connector body 1; a battery core 3, matching the cable, is installed through the middle of the inner side of the connector body 1, allowing the two cables inserted into the mating grooves 2 to be connected through the battery core; a rubber sleeve 4 is fixedly fitted on the inner ring surface of the mating groove 2, the inner diameter of the rubber sleeve being adapted to the cable, thereby increasing the sealing between the rubber sleeve and the outer ring surface of the cable; and a jacking plate is provided on one side of the mating groove 2. The movable clamping plate 5 has an arc-shaped bottom and a rubber block 6 is fixedly connected inside the arc surface. The arc-shaped clamping plate 5 and the rubber block 6 can better fit with the cable, thereby improving the stability of the cable clamping. The rubber block 6 has anti-slip texture 7 on one side. The anti-slip texture 7 on the rubber block 6 further improves the clamping stability and avoids displacement, shaking or loosening between the cable and the connecting body 1. The top of the clamping plate 5 is connected to a driving component for driving the relative movement of the clamping plate 5. A limiting component for limiting the driving component is provided in the middle of the upper surface of the connector body 1.

[0023] In use, two cables are inserted into the connecting body 1 through the rubber sleeves 4 set in the docking groove 2. The rubber 4 fits tightly against the outer surface of the cable to achieve a sealing effect. At the same time as insertion, the cable ends are connected to the battery core 3. After connection is completed, the two clamping plates 5 are driven by the drive component to move towards each other until the rubber block 6 on one side of the clamping plate 5 comes into tight contact with the outer surface of the cable, thus firmly clamping it. In addition, the anti-slip texture 7 on the rubber block 6 further improves the clamping stability and prevents loosening. Finally, the drive component is limited by the limiting component to prevent the drive component from moving in the opposite direction, further ensuring that the cable is not loosened from the connecting body 1.

[0024] The drive assembly includes an H-shaped frame 8, which is mounted on the upper side of the connector body 1. Sliding pins 9 are fixedly sleeved at both ends of the H-shaped frame 8. A drive rod 10 is rotatably sleeved in the middle of the H-shaped frame 8. Two limiting pieces 11 are fixedly sleeved on the drive rod 10. The upper and lower limiting pieces 11 are respectively attached to the upper and lower surfaces of the H-shaped frame 8. The drive rod 10 is limited within the H-shaped frame 8 by the contact between the limiting pieces 11 and the H-shaped frame 8. Guide plates 12 are fixedly connected to both ends of the upper surface of the connector body 1. Sliding blocks 13 are slidably connected to both ends of one side of the guide plates 12. The guide plates 12 guide and limit the sliding blocks 13. A connecting block 14 is fixedly connected to the top of the sliding block 13. An arc-shaped hole 15 is opened on the surface of the connecting block 14. The bottom of the connecting block 14 is fixedly connected to the clamping plate 5. The arc-shaped hole 15 is slidably connected to the sliding pins 9.

[0025] Once the cable is connected, pressing down on the drive rod 10 causes the limiting plate 11 to limit the movement of the drive rod 10, which in turn causes the H-frame 8 to move downwards synchronously. The H-frame 8 slides within the arc-shaped hole 15 in the connecting block 14 via the sliding pins 9 fixedly connected to its two ends, thereby pushing the connecting block 14 to move. This causes the connecting block 14 to move the slider 13. The two sliders 13 move towards each other under the limiting guidance of the guide plate 12. Subsequently, the sliders 13 drive the clamping plate 5 to move synchronously, causing the clamping plate 5 to move towards the outer surface of the cable until the rubber block 6 is in close contact with the cable. This completes the clamping and limiting of the cable, preventing the connection from loosening. At the same time, the rubber block 6 provides cushioning to prevent damage from clamping, thus enhancing safety.

[0026] An arc-shaped piece 16 is fixedly connected to the bottom of the drive rod 10. The arc-shaped piece 16 is symmetrically arranged about the drive rod 10. The limiting component includes a limiting platform 17. The lower surface of the limiting platform 17 is fixedly connected to the middle of the upper surface of the connector body 1. The limiting platform 17 is hollow. An arc-shaped groove 18 matching the arc-shaped piece 16 is opened in the middle of the upper surface of the limiting platform 17. The arc-shaped piece 16 and the arc-shaped groove 18 are slidably connected. A limiting hole 19 is opened at the end of the arc-shaped piece 16 away from the drive rod 10. Stepped holes 20 are opened on both sides of the upper surface of the limiting platform 17. The top of the stepped hole 20 is fixedly connected to the top of the pin 22 through a return spring 21. The bottom of the stepped hole 20 is slidably inserted into the bottom of the pin 22, and the bottom of the pin 22 passes through the stepped hole 20 and is adapted to the limiting hole 19.

[0027] When the drive rod 10 is pressed down, it slides into the limiting platform 17. The arc-shaped piece 16, which is fixedly connected to its bottom, moves into the limiting platform 17 under the limitation of the arc-shaped groove 18 until it abuts against the inner side of the top of the limiting platform 17. At this time, the pin 22 is pulled up, and the pin 22 stretches the return spring 21. Then, by twisting the drive rod 10 ninety degrees, the stepped hole 20 is made coaxial with the limiting hole 19. Then the pin 22 is released. Under the reverse elastic force of the return spring 21, the bottom of the pin 22 is inserted into the limiting hole 19, thereby limiting the arc-shaped piece 16, then limiting the drive rod 10, and then limiting the H-shaped frame 8, preventing the movement of the H-shaped frame 8 and ensuring the stability of the clamping plate 5 for the cable. When it is necessary to disassemble the cable, the pin 22 is pulled up, and then the drive rod 10 is twisted ninety degrees in the opposite direction. Pulling the drive rod 10 up can indirectly release the limitation of the clamping plate 5, and thus release the limitation of the cable.
