Description

Technical Field

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

[0002] Cable equipment is a general term for systematic devices and tools used in the fields of power, communication, and data transmission for cable laying, installation, connection, protection, and management. Its core function is to realize the safe and efficient transmission of electrical energy or signals. As a key component in cable equipment, cable connectors undertake the tasks of physical connection, electrical conduction, and signal transmission between cables or between cables and equipment. Their performance directly affects the reliability and stability of the entire system.

[0003] Common cable connectors are usually plugged directly together during use, lacking the ability to buffer external forces. When the cable is subjected to external force, the two cable connectors are prone to breakage, resulting in transmission interruption. Therefore, there is an urgent need for a cable connector with buffering function to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable connector with a buffer function, which has the advantages of buffering external forces on the cable and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable connector with a buffer function, comprising two connector bodies, which are inserted into each other. A buffer frame is slidably connected to one end of each connector body along its axis away from each other. A buffer spring is fixedly connected to the inner wall of each buffer frame. The other end of each buffer spring is fixedly connected to the inner wall of the connector body adjacent to it. A cable body is electrically connected to the end of each connector body. A rubber fastening sleeve is fitted onto the outer surface of each cable body along its axial direction. Both rubber fastening sleeves are in contact with the inner wall of the buffer frame adjacent to them.

[0006] Furthermore, the inner walls of the two connector bodies at their opposite ends are each provided with a rubber sealing ring, and the inner walls of the two connector bodies at their opposite ends are each threaded with a pressing member, and the two pressing members are in contact with their adjacent rubber sealing rings.

[0007] The above solution, by setting the rubber sealing ring and the extrusion component together, can greatly enhance the sealing performance at the connection between the connector body and the buffer frame. The rubber sealing ring itself has good elasticity and sealing performance. When the extrusion component is gradually tightened through the threaded connection and squeezes the rubber sealing ring, the sealing ring will deform and fit tightly against the connection part, effectively preventing external dust, moisture and other impurities from entering the buffer cavity.

[0008] Furthermore, a set of positioning grooves is provided on the outer surface of both connector bodies, and the protruding parts of the inner walls of the two buffer frames are slidably connected to the positioning grooves adjacent to them.

[0009] The above solution, which uses a sliding connection between the positioning groove and the protruding part of the inner wall of the buffer frame, provides guidance for the sliding of the buffer frame on the connector body. This ensures that the buffer frame always moves in the predetermined direction when it is slid under external force, avoiding deviation or shaking.

[0010] Furthermore, a threaded slot is provided between the two connector bodies, and a T-shaped threaded connector is provided between the two connector bodies, the threaded connector being threadedly connected to the two threaded slots.

[0011] The above solution, which uses a T-shaped threaded connector to connect with a threaded groove, provides a stable and reliable connection between the two connector bodies. This allows the two connector bodies to effectively withstand various tensile and torsional forces that the cable connector is subjected to during use, preventing the two connector bodies from loosening or separating.

[0012] Furthermore, both cable bodies are coiled and located within a buffer frame adjacent to them.

[0013] Through the above scheme, the coiled cable body can increase its flexibility and extensibility to a certain extent. When the cable is pulled by external force, the coiled part can freely extend and contract, thereby better adapting to changes in external force and avoiding damage to the cable due to excessive stretching.

[0014] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0015] This type of cable connector with buffer function, through the cooperation of a buffer frame and a buffer spring, can gradually dissipate and buffer the external force when the cable body is pulled by an external force, by utilizing the elastic force generated during the deformation of the buffer spring. This effectively reduces the direct impact of the external force on the overall system. At the same time, the cable body is coiled inside the buffer frame, which can prevent the cable body from becoming taut under the action of external force. The external force is first absorbed by the buffer frame and spring, thereby cutting off the transmission path of the external force to the connection point, providing a strong guarantee for the stable connection of the connector.

[0016] Secondly, the combination of the rubber fastening sleeve and the rubber sealing ring can create a sealed buffer cavity between the buffer frame and the connector body. When the buffer frame slides on the connector body, the pressure inside the cavity will change. This pressure change will generate a reverse traction force acting on the buffer frame, thereby providing secondary buffering of the external force borne by the cable body. Through the double buffering mechanism, the external force transmitted to the connection point of the two connector bodies is greatly reduced, ensuring that the two connector bodies can always maintain a stable and reliable connection state under various complex external force environments.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Please see Figures 1-4 This embodiment of a cable connector with a buffer function includes two connector bodies 1, which are inserted into each other. Buffer frames 2 are slidably connected to the ends of the two connector bodies 1 that are far apart from each other along their axes. Buffer springs 3 are fixedly connected to the inner walls of the two buffer frames 2, and both buffer springs 3 are in a reset state. The other ends of the two buffer springs 3 are fixedly connected to the inner walls of the connector bodies 1 that are close to them. Cable bodies 4 are electrically connected to the ends of the two connector bodies 1. Rubber fastening sleeves 5 are sleeved on the outer surfaces of the two cable bodies 4 along their axial direction, and both rubber fastening sleeves 5 are in contact with the inner walls of the buffer frames 2 that are close to them.

[0025] By setting up the buffer frame 2 and the buffer spring 3 together, when the cable body 4 is pulled by external force, the elastic force generated during the deformation of the buffer spring 3 can be used to gradually dissipate and buffer the external force, effectively reducing the direct impact of the external force on the overall system. At the same time, the cable body 4 is curled up inside the buffer frame 2, which can prevent the cable body 4 from becoming taut under the action of external force. The external force is first absorbed by the buffer frame 2 and the spring, thereby cutting off the transmission path of the external force to the connection point, providing a strong guarantee for the stable connection of the connector.

[0026] Secondly, the combination of the rubber fastening sleeve 5 and the rubber sealing ring 6 can create a sealed buffer cavity between the buffer frame 2 and the connector body 1. When the buffer frame 2 slides on the connector body 1, the pressure inside the cavity will change. This pressure change will generate a reverse traction force acting on the buffer frame 2, thereby providing secondary buffering for the external force borne by the cable body 4. Through the double buffering mechanism, the external force transmitted to the connection point of the two connector bodies 1 is greatly reduced, ensuring that the two connector bodies 1 can always maintain a stable and reliable connection state under various complex external force environments.

[0027] Rubber sealing rings 6 are provided on the inner walls of the two connector bodies 1 at their far ends. Extrusion members 7 are threadedly connected to the inner walls of the two connector bodies 1 at their far ends. Both extrusion members 7 are in contact with their adjacent rubber sealing rings 6. By setting the rubber sealing rings 6 and extrusion members 7 to cooperate, the sealing performance at the connection between the connector body 1 and the buffer frame 2 can be greatly enhanced. The rubber sealing ring 6 itself has good elasticity and sealing performance. When the extrusion members 7 are gradually tightened through the threaded connection and squeeze the rubber sealing ring 6, the sealing ring will deform and fit tightly against the connection part, effectively preventing external dust, moisture and other impurities from entering the buffer cavity.

[0028] Each of the two connector bodies 1 has a set of positioning grooves 8 on its outer surface. The protruding parts of the inner walls of the two buffer frames 2 are slidably connected to the positioning grooves 8 adjacent to them. The sliding connection design between the positioning grooves 8 and the protruding parts of the inner walls of the buffer frames 2 provides guidance for the sliding of the buffer frames 2 on the connector bodies 1, ensuring that the buffer frames 2 always move in a predetermined direction when they are slid under external force, avoiding deviation or shaking. A threaded slot 9 is provided between the two connector bodies 1, and a T-shaped threaded connector 10 is provided between the two connector bodies 1. The threaded connector 10 is threadedly connected to the two threaded slots 9, forming a T-shape. The threaded connection 10 and the threaded groove 9 provide a stable and reliable connection for the two connector bodies 1, enabling the two connector bodies 1 to effectively withstand various tensile and torsional forces on the cable connector during use, preventing loosening or separation between the two connector bodies 1. Both cable bodies 4 are coiled and located in the buffer frame 2 close to them. The coiled cable bodies 4 can increase their flexibility and extensibility to a certain extent. When the cable is pulled by external force, the coiled part can freely extend and contract, thereby better adapting to changes in external force and avoiding damage to the cable due to excessive stretching.

[0029] The working principle of the above embodiment is as follows: When the cable body 4 is pulled by an external force, the cable body 4 will drive the rubber fastening sleeve 5 to slide inside the buffer frame 2, causing the internal pressure of the buffer frame 2 to change. Since the cable body 4 is coiled inside the buffer frame 2, the cable body 4 can freely expand and contract within the buffer frame 2, preventing the cable body 4 from becoming too tight and causing the cable body 4 to break off from the connector body 1. When the rubber fastening sleeve 5 contacts the inner wall of the buffer frame 2, the external force will be transmitted to the buffer frame 2, causing the buffer frame 2 to slide on the outer surface of the connector body 1 and stretch the buffer spring 3, gradually dissipating and buffering the external force, effectively reducing the direct impact of the external force on the overall system. When the buffer frame 2 slides on the outer surface of the connector body 1, the pressure inside the buffer frame 2 will change significantly. The pressure change will generate a reverse traction force acting on the buffer frame 2, thereby providing secondary buffering of the external force borne by the cable body 4, ensuring that the two connector bodies 1 can always maintain a stable and reliable connection state under various complex external force environments.
