Description

Technical Field

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

[0002] In the field of power transmission, snap-fit ​​self-locking cable connectors are a common connection device used to connect two cable segments. To a certain extent, they meet the basic requirements of cable connection. However, with the development of technology and the diversification of application scenarios, their shortcomings have gradually become apparent.

[0003] Existing cable connectors generally include a housing, a shell, a connecting sleeve, and end sleeves. The shell is flat, with its left end fitting onto the right end of the housing, and its right end fitting onto the left end of the end sleeve. The connecting sleeve is fitted onto the shell. An axial limiting structure is provided at the junction of the shell and the connecting sleeve, and an axial limiting structure is also provided at the junction of the shell and the end sleeve. The drawbacks of this type of cable connector are that the connection between the shell and the end sleeve is relatively cumbersome, and its self-locking performance is poor. To address these issues, we propose a self-locking cable connector. Utility Model Content

[0004] The purpose of this invention is to provide a self-locking cable connector to solve the problems mentioned in the background art, such as the cumbersome operation and poor self-locking performance of existing cable connectors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-locking cable connector, comprising a cable one and a cable two, wherein cable one and cable two are respectively provided at opposite ends, cable connector one and cable connector two are inserted into cable connector one, cable connector one is threadedly connected to cable connector one, a limit sleeve is embedded in the end face of the limit sleeve away from cable one, the return spring is arranged in a ring on the limit sleeve, a sliding sleeve is movably sleeved on the outside of the limit sleeve, the return spring is located inside the sliding sleeve, and the right end of the return spring contacts the sliding sleeve, an L-shaped groove is opened in a ring on the side of cable connector one away from cable one, and a guide groove is opened in a ring on the inner side of the sliding sleeve; The cable connector 2 has a guide block arranged in a ring shape on the side away from the cable 2. The guide block is slidably connected inside the guide groove. The inner side of the cable connector 2 has a limiting block arranged in a ring shape and slidably connected inside the L-shaped groove.

[0006] Preferably, the sliding sleeve is movably fitted onto the second cable connector, and the outer diameter of the second cable connector is larger than the outer diameter of the first cable connector.

[0007] Preferably, the limiting block is located on the inner side of the adjacent guide block.

[0008] Preferably, the width of the limiting block is equal to the width of the L-shaped groove.

[0009] Preferably, the width of the guide block is equal to the width of the guide groove.

[0010] Preferably, the number of guide blocks and limiting blocks are equal, and the included angle between the guide blocks and limiting blocks is 45 degrees.

[0011] Preferably, the L-shaped groove includes a radial side and an axial side, and the length of the limiting block is equal to the groove width of the radial side.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This self-locking cable connector features a limiting sleeve threaded onto the outer side of cable connector one, and a sliding sleeve slidably fitted onto the outer side of the limiting sleeve. A return spring connects the sliding sleeve and the limiting sleeve. The elastic return spring's action allows the guide groove inside the sliding sleeve to engage the guide block, enabling relative rotation between cable connector one and cable connector two. This aligns the axial position of the limiting block and the L-shaped groove. During the sliding of the limiting block from the axial side to the radial side, cable connector two needs to be rotated to move the limiting block into the radial side, thus restricting the relative axial position of cable connector one and cable connector two. This structure allows for quick and easy connection of cable connector one and cable connector two, providing excellent self-locking performance and saving time and effort. Furthermore, replacing the return spring simply requires unscrewing the limiting sleeve from cable connector one, making operation convenient and further ensuring the cable connection effect.

[0015] 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.

[0016] Example: Please refer to Figure 1-5 This utility model provides a technical solution: a self-locking cable connector, comprising a cable 1 and a cable 2, wherein cable 1 and cable 2 are respectively provided with cable connector 11 and cable connector 21 at their opposite ends, cable connector 21 being inserted into cable connector 11, wherein the core wires inside cable 1 and cable 2 pass through the corresponding cable connector 11 and cable connector 21, and after cable connector 11 and cable connector 21 are connected, cable 1 and cable 2 can be electrically connected.

[0017] Please see Figure 1-2 The cable connector 11 is threadedly connected to a limiting sleeve 14. The cable connector 11 has a thread for connecting to the limiting sleeve 14. By rotating the limiting sleeve 14, the position on the cable connector 11 can be changed.

[0018] Furthermore, a reset spring 15 is embedded in the end face of the limiting sleeve 14 away from the cable 1. A groove with a circular cross-section is opened on the corresponding end face of the limiting sleeve 14. The number of grooves is equal to the number of reset springs 15. The grooves can play a certain guiding and positioning role for the reset springs 15.

[0019] Furthermore, the return spring 15 is annularly mounted on the limiting sleeve 14. A sliding sleeve 12 is movably fitted around the outer side of the limiting sleeve 14. The return spring 15 is located inside the sliding sleeve 12, and its right end contacts the sliding sleeve 12. The return spring 15 allows the sliding sleeve 12 to cover the cable connector 11 as needed. Replacing the return spring 15 simply requires unscrewing the limiting sleeve 14 from the cable connector 11, making the operation convenient and further ensuring the cable connection effect.

[0020] Furthermore, an L-shaped groove 13 is provided in an annular shape on the side of the cable connector 11 away from the cable 1. The L-shaped groove 13 includes a radial side and an axial side. The radial side can limit the position of the sliding component inside, while the axial side can guide the sliding component inside.

[0021] Furthermore, a guide groove 16 is annularly formed on the inner surface of the sliding sleeve 12; a guide block 22 is annularly formed on the side of the cable connector 21 away from the cable 2, and the guide block 22 is slidably connected inside the guide groove 16, the width of the guide block 22 being equal to the width of the guide groove 16. The sliding sleeve 12 is movably fitted onto the cable connector 21, and the outer diameter of the cable connector 21 is larger than the outer diameter of the cable connector 11. After the axial positions of the guide block 22 and the guide groove 16 correspond, the sliding sleeve 12 slides to the outside of the cable connector 21 by the elastic reset action of the return spring 15, thereby restricting the relative rotation of the cable connector 11 and the cable connector 21.

[0022] In this example, a limiting block 23, which is slidably connected to the L-shaped groove 13, is arranged in a ring shape on the inner side of the cable connector 21. The limiting block 23 is located in the middle of the adjacent guide block 22. The width of the limiting block 23 is equal to the width of the L-shaped groove 13. The length of the limiting block 23 is equal to the width of the radial side of the groove. When the limiting block 23 slides inside the L-shaped groove 13, it slides from the axial side to the radial side. At this time, the axial side guides the limiting block 23, while the radial side restricts its position, preventing it from moving along the axis of the cable connector 21. During the process of the limiting block 23 sliding from the axial side to the radial side, the cable connector 21 needs to be rotated. During this process, the axial positions of the guide block 22 and the guide groove 16 inside the sliding sleeve 12 correspond, which facilitates the insertion and connection of the cable connector 11 and the cable connector 21.

[0023] It is worth noting that the number of guide blocks 22 and limiting blocks 23 are equal, and the included angle between guide blocks 22 and limiting blocks 23 is 45 degrees. In the initial state, the guide blocks 22 and guide grooves 16 are staggered. However, as the cable connector 21 rotates, causing the limiting block 23 to slide from the axial side to the radial side, the axial positions of the guide blocks 22 and the guide grooves 16 inside the sliding sleeve 12 will correspond, thus facilitating the insertion and connection of cable connector 11 and cable connector 21.

[0024] Working principle: When using this self-locking cable connector to connect cable 1 and cable 2, cable connector 21 is inserted into cable connector 11. At this time, the axial positions of the limiting block 23 and the L-shaped groove 13 are aligned. During the process of sliding the limiting block 23 from the axial side to the radial side, cable connector 21 needs to be rotated to move the limiting block 23 into the radial side, thereby restricting the relative axial positions of cable connector 11 and cable connector 21. During the relative rotation of cable connector 21 and cable connector 11, the axial positions of the guide block 22 and the guide groove 16 inside the sliding sleeve 12 are aligned. At this time, cable connector 11 and cable connector 21 will not rotate relative to each other, thus facilitating the insertion and connection of cable connector 11 and cable connector 21.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
