Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable technology, specifically to an anti-vibration cable accessory with anti-extrusion function. Background Technology
[0002] Cable accessories are commonly used to connect two cables during installation, as well as to create terminal joints. The joints between two cables are connected using metal connectors, and then heat-shrink tubing is used to heat-shrink the connection point for insulation.
[0003] Cable connectors are typically secured by clamping cables with bolts. In construction sites, vibrations generated during construction work can affect the connectors and bolts, causing the bolts to loosen and consequently loosening the connectors. Therefore, as an important accessory for cable connections, it is crucial to optimize the connectors for shock and pressure resistance. To this end, we propose a shock-resistant cable accessory with anti-crushing function. Utility Model Content
[0004] The purpose of this invention is to provide a shock-resistant cable accessory with anti-crushing function to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant cable accessory with anti-extrusion function, comprising a first sleeve, a first damping component disposed on the inner wall of the first sleeve, the first damping component comprising a first damper for consuming vibration energy, one end of the first damper being fixedly connected to the inner wall of the first sleeve, the other end of the first damper being fixedly connected to a first abutment, a first damping spring for soft connection buffering being disposed between the first abutment and the inner wall of the first sleeve, and the first damping spring being sleeved on the side surface of the first damper, and a connecting component being disposed on one side of the first sleeve.
[0006] Preferably, the connecting assembly includes an internal threaded groove, which is formed inside the first sleeve. The internal threaded groove is threadedly connected to a threaded sleeve, and a second sleeve is fixedly connected to one side of the threaded sleeve.
[0007] Preferably, a second damping assembly is provided inside the second sleeve. The second damping assembly includes a second damper. One end of the second damper is fixedly connected to the inner wall of the second sleeve, and the other end of the second damper is fixedly connected to a second abutment. A second damping spring is provided between the inner wall of the second sleeve and the second abutment, and the second damping spring is sleeved on the side surface of the second damper.
[0008] Preferably, a first elastic ring is fixedly sleeved on the inner edge of the first sleeve at the end away from the second sleeve, and an insulating layer for cable insulation is sleeved on the inner ring surface of the first elastic ring.
[0009] Preferably, a second elastic ring is fixedly sleeved on the inner edge of the second sleeve at the end away from the first sleeve, and the inner ring surface of the second elastic ring is sleeved on the insulation layer of the cable.
[0010] Preferably, a wire core is sleeved inside the insulating layer, and a connector is sleeved at the connection position of the two wire cores, with a threaded hole inside the connector.
[0011] Preferably, the threaded hole is internally threaded with a fixing bolt, which rotates within the threaded hole to press one end of the fixing bolt against the wire core, and the side surface of the connector is fitted with a heat shrink tubing for insulation protection.
[0012] Compared with the prior art, the beneficial effects of this utility model are: The first and second damping components weaken the vibration energy generated during construction by transmitting it to the first and second sleeves. The vibration energy is then reduced by the action of the first damper, the first damping spring, the second damper, and the second damping spring, thereby reducing the transmission of vibration energy to the connector. This allows the fixing bolts to be effectively tightened on the connector, thus improving the stability of the connection between the two cables.
[0013] The first and second sleeves are connected by internal thread grooves and threaded sleeves, which allows for quick fixation after wiring. The heat shrink tubing and the connector protrusion limit the first and second sleeves, preventing them from sliding freely on the cable after tightening. This ensures that the first and second sleeves are always in the position of the connector, thereby improving the effectiveness of shock absorption. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides a technical solution: such as Figures 1-4 The diagram shows a shock-resistant cable accessory with anti-crushing function, comprising a first sleeve 1. A first damping component is provided on the inner wall of the first sleeve 1. The first damping component includes a first damper 3 for absorbing vibration energy. One end of the first damper 3 is fixedly connected to the inner wall of the first sleeve 1, and the other end is fixedly connected to a first abutment 4. A first damping spring 5 for flexible connection buffering is provided between the first abutment 4 and the inner wall of the first sleeve 1, and the first damping spring 5 is sleeved on the side surface of the first damper 3. A connecting component is provided on one side of the first sleeve 1. In use, the excessively long cable is cut off so that the interfaces of the two cables are flush. Then, the insulation layer 12 at the two interfaces is stripped using a wire stripping tool to expose the wire core 13. Subsequently, the first sleeve 1, the second sleeve 2, and the heat shrink tubing 8 are sleeved onto the cable through the unconnected interfaces. Then, the wire core 13 at the two interfaces is connected to the cable. Both ends of the connector 9 are inserted into the connector 9. Then, by tightening the fixing bolt 11, one end of the fixing bolt 11 is pressed against the wire core 13, fixing the wire core 13 between the inner wall of the connector 9 and the fixing bolt 11, thus forming a tight connection between the two cables. Then, the heat shrink tubing 8 is moved to the connector 9 and wrapped with heat to form insulation. Finally, the first sleeve 1 and the second sleeve 2 are brought close to each other and tightened by the internal thread groove 6 and the threaded sleeve 7. When vibration occurs, the vibration is transmitted through the first sleeve 1 and the second sleeve 2, so that the first damping spring 5 and the second damping spring 16 store the vibration energy. The first damping spring 5 and the second damping spring 16 achieve a soft connection between the first sleeve 1 and the second sleeve 2 and the connector 9. Then, the vibration energy is consumed by the first damper 3 and the second damper 14, thereby weakening the direct effect of external vibration and pressure on the connector 9.
[0018] like Figures 1-3 As shown, the connecting assembly includes an internal threaded groove 6, which is formed inside the first sleeve 1. The internal threaded groove 6 is threadedly connected to a threaded sleeve 7, and a second sleeve 2 is fixedly connected to one side of the threaded sleeve 7.
[0019] like Figures 1-3 As shown, a second damping assembly is provided inside the second sleeve 2. The second damping assembly includes a second damper 14. One end of the second damper 14 is fixedly connected to the inner wall of the second sleeve 2, and the other end of the second damper 14 is fixedly connected to a second abutment 15. A second damping spring 16 is provided between the inner wall of the second sleeve 2 and the second abutment 15, and the second damping spring 16 is sleeved on the side surface of the second damper 14.
[0020] like Figures 1-3 As shown, a first elastic ring 17 is fixedly sleeved on the inner edge of the first sleeve 1 away from the second sleeve 2, and an insulation layer 12 for cable insulation is sleeved on the inner ring surface of the first elastic ring 17.
[0021] like Figures 1-4 As shown, a second elastic ring 18 is fixedly sleeved on the inner edge of the second sleeve 2 away from the first sleeve 1. The inner ring surface of the second elastic ring 18 is sleeved on the insulation layer 12 of the cable. Through the first damping component and the second damping component, the vibration generated by the construction site is transmitted to the first sleeve 1 and the second sleeve 2. Under the action of the first damper 3, the first damping spring 5, the second damper 14 and the second damping spring 16, the vibration energy is weakened, thereby reducing the vibration energy transmitted to the connector 9. This allows the fixing bolt 11 to be effectively tightened on the connector 9, thereby improving the stability of the connection between the two cables. The first sleeve 1 and the second sleeve 2 are threadedly connected by the internal thread groove 6 and the threaded sleeve 7, which allows for quick fixing after the wiring is completed. The first sleeve 1 and the second sleeve 2 are limited by the heat shrink tubing 8 and the protrusion of the connector 9, so that the first sleeve 1 and the second sleeve 2 cannot slide freely on the cable after tightening. This ensures that the first sleeve 1 and the second sleeve 2 are always in the position of the connector 9, thereby improving the effectiveness of vibration damping.
[0022] like Figure 2 and Figure 3 As shown, a wire core 13 is sleeved inside the insulation layer 12, and a connector 9 is sleeved at the connection position of the two wire cores 13. A threaded hole 10 is opened inside the connector 9.
[0023] like Figure 2 and Figure 3 As shown, a fixing bolt 11 is connected to the internal thread of the threaded hole 10. The fixing bolt 11 rotates in the threaded hole 10, so that one end of the fixing bolt 11 abuts against the wire core 13. A heat shrink tubing 8 for insulation protection is sleeved on the side surface of the connector 9.
[0024] Working principle: During use, cut off the excessively long cable so that the interfaces of the two cables are flush. Then, use a wire stripper to strip the insulation layer 12 at both interfaces, exposing the wire core 13. Next, slip the first sleeve 1, the second sleeve 2, and the heat shrink tubing 8 onto the cable through the unconnected interfaces. Then, insert the wire core 13 from both ends of the connector 9 into the connector 9. Then, tighten the fixing bolt 11, so that one end of the fixing bolt 11 presses against the wire core 13, fixing the wire core 13 between the inner wall of the connector 9 and the fixing bolt 11, thus securing the interfaces of the two cables. Finally, apply the heat shrink tubing... 8 is moved to the connector 9 and wrapped by heating to form insulation. Finally, the first sleeve 1 and the second sleeve 2 are brought close to each other and fastened by the internal thread groove 6 and the threaded sleeve 7. When vibration occurs, the vibration is transmitted through the first sleeve 1 and the second sleeve 2, so that the first damping spring 5 and the second damping spring 16 store the vibration energy. The first damping spring 5 and the second damping spring 16 realize the soft connection between the first sleeve 1 and the second sleeve 2 and the connector 9. Then, the vibration energy is consumed by the first damper 3 and the second damper 14, thereby weakening the direct effect of external vibration and pressure on the connector 9.
