Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically an anti-loosening connector. Background Technology

[0002] Electrical connectors are an indispensable key component in modern electronic devices and electrical systems. Their core function is to achieve reliable transmission of current or signals, and connection stability is an important foundation for ensuring reliable transmission.

[0003] Currently, anti-loosening connectors typically employ either a snap-fit ​​or threaded structure. Snap-fit ​​structures use springs or pins for quick insertion, removal, and locking, offering advantages such as ease of operation, rapid connection, and clear feedback. However, under continuous or strong vibration, their locking force is limited, and there remains a risk of accidental disengagement. Threaded structures securely lock the male and female sockets together by rotating a threaded sleeve, providing extremely high locking force and excellent vibration resistance. However, operation is relatively cumbersome, and the connection and disconnection processes are time-consuming, causing inconvenience during on-site installation. Utility Model Content

[0004] This invention provides a connector that prevents loosening, solving the problem that traditional connectors cannot simultaneously achieve both ease of operation and secure connection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening connector, comprising:

[0006] The male plug body has a locking hole, and an anti-loosening component is slidably installed on the outside of the male plug body. The anti-loosening component includes a threaded sleeve and a movable ring. The threaded sleeve and the movable ring are rotatably connected and the movable ring is slidably connected to the male plug body. The rotation direction of the threaded sleeve intersects the sliding direction of the movable ring.

[0007] The female socket body is adapted to the male plug body. The outer wall of the female socket body is provided with threads that are adapted to the threaded sleeve. A second anti-loosening component is fixed on the female socket body. The second anti-loosening component includes a mounting ring, which is fixedly connected to one end of the female socket body. The mounting ring is provided with a locking block that engages with the locking hole.

[0008] In some embodiments, the threaded sleeve and the movable ring are both sleeved on the outer wall of the male plug body, two limiting blocks are symmetrically arranged on the inner wall of the movable ring, and two limiting grooves are symmetrically arranged on the outer wall of the male plug body, with the limiting blocks slidably installed in the corresponding limiting grooves.

[0009] In some embodiments, the distance between the end of the limiting groove near the top of the opening of the male plug body and the top of the opening of the male plug body is less than the width of the threaded sleeve.

[0010] In some embodiments, one end of the movable ring is provided with a T-shaped limiting ring, and one end of the threaded sleeve is provided with a T-shaped limiting groove that matches the limiting ring, and the limiting ring is rotatably connected in the T-shaped limiting groove.

[0011] In some embodiments, the mounting ring is symmetrically provided with elastic locking rods on its outer side, and the locking block is disposed at the other end of the elastic locking rods; the inner wall of the male plug body is provided with a guide groove adapted to the elastic locking rods, and the locking hole is disposed at the other end of the guide groove.

[0012] In some embodiments, the mounting ring has a first mounting hole, and one end of the female socket body has a mounting groove. The mounting groove has a second mounting hole that matches the first mounting hole, and the first mounting hole and the second mounting hole are fixedly connected by screws.

[0013] In some embodiments, the elastic lever is a metal elastic lever or a plastic elastic lever.

[0014] In some embodiments, a guide sleeve is provided inside the male plug body surrounding the male plug pins, and the guide sleeve is adapted to the female socket pin seat of the female socket body.

[0015] In some embodiments, the rotation direction of the threaded sleeve is perpendicular to the sliding direction of the movable ring. Beneficial effects

[0016] This invention provides a connector that prevents loosening. Compared with the prior art, it has the following advantages:

[0017] (1) This utility model ingeniously constructs a dual anti-loosening system that combines quick snap-fit ​​and powerful threaded locking by setting a first anti-loosening component and a second anti-loosening component. When the connector is inserted, the elastic lever and the locking block of the second anti-loosening component can first cooperate with the locking hole on the inner wall of the male plug body to achieve quick and reliable initial positioning and locking. This not only provides the operator with clear tactile and audible feedback of being in place, but also ensures that the connector will not accidentally separate before proceeding to the next step of threaded locking. Subsequently, by tightening the threaded sleeve of the first anti-loosening component, a second, more powerful threaded locking can be achieved. This locking force is sufficient to resist severe vibration and impact, thereby greatly ensuring the final reliability and stability of the connection and effectively overcoming the limitations of a single locking method in terms of convenience or reliability.

[0018] (2) This utility model significantly simplifies the connector disassembly process through the linkage design of the first and second anti-loosening components. During disassembly, the user only needs to loosen the threaded sleeve and then pull the first anti-loosening component backward. The movable ring and limiting block on it will squeeze and release the locking state of the second anti-loosening component, and the male plug body will be pulled out of the female socket body. This integrated unlocking and pulling action combines multiple operations that originally needed to be performed step by step into a single continuous action, eliminating the need for the user to manually press the locking block, greatly improving the convenience and efficiency of operation, especially in situations where space is limited or frequent plugging and unplugging is required. At the same time, the second anti-loosening component can be easily disassembled and replaced if damaged. Attached Figure Description

[0025] 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.

[0026] See Figures 1 to 4 The present invention provides an anti-loosening connector, comprising:

[0027] The male plug body 1 has a locking hole 11. A first anti-loosening component 12 is slidably installed on the outside of the male plug body 1. The first anti-loosening component 12 includes a threaded sleeve 121 and a movable ring 122. The threaded sleeve 121 and the movable ring 122 are rotatably connected and limited. One end of the movable ring 122 is slidably connected to the male plug body 1 and limited. The rotation direction of the threaded sleeve 121 intersects the sliding direction of the movable ring 122.

[0028] The female socket body 2 is adapted to the male plug body 1. The outer wall of the female socket body 2 is provided with thread teeth 21 that are adapted to the threaded sleeve 121. A second anti-loosening component 22 is fixed on the female socket body 2. The second anti-loosening component 22 includes a mounting ring 221. The mounting ring 221 is fixedly connected to one end of the female socket body 2. The mounting ring 221 is provided with a locking block 222 that engages with the locking hole 11.

[0029] In this embodiment, the anti-loosening connector features an ingenious structural design. Through a double anti-loosening structure, it ensures the stability and reliability of the connection, effectively preventing accidental disconnection due to external factors such as vibration. The guide sleeve 15, the first anti-loosening component 12, and the second anti-loosening component 22 are included. The second anti-loosening component 22 includes a mounting ring 221 with a locking block 222 that matches the locking hole 11 on the male plug body 1. The female socket body 2 engages with the locking hole 11 on the male plug body 1 via the locking block 222, achieving a first layer of locking. The first anti-loosening component 12 includes a threaded sleeve 121 and a movable ring 12. Both the threaded sleeve 121 and the movable ring 122 are slidably fitted onto the outer wall of the male plug body 1. The male plug body 1 is threadedly connected to the threaded teeth 21 on the female socket body 2 via the threaded sleeve 121, achieving a second layer of locking.

[0030] In some embodiments, the rotation direction of the threaded sleeve 121 is perpendicular to the sliding direction of the movable ring 122, thereby improving ease of operation.

[0031] In some embodiments, such as Figure 3 As shown, one end of the movable ring 122 is provided with a T-shaped limiting ring 124, and one end of the threaded sleeve 121 is provided with a T-shaped limiting groove 125 that is adapted to the limiting ring 124. The limiting ring 124 is rotatably connected in the T-shaped limiting groove 125.

[0032] In this embodiment, a sophisticated connection structure is designed to allow the threaded sleeve 121 to rotate relative to the movable ring 122 while maintaining axial linkage between the two. Specifically, a T-shaped limiting ring 124 is integrally formed at the end of the movable ring 122 that connects to the threaded sleeve 121. Correspondingly, a T-shaped limiting groove 125 is formed on the inner wall of the end of the threaded sleeve 121 facing the movable ring 122, which mates with the limiting ring 124. This allows the limiting ring 124 to rotate freely within the T-shaped limiting groove 125, while simultaneously allowing the threaded sleeve 121 to rotate relative to the movable ring 122.

[0033] In some embodiments, the distance between the end of the limiting groove 13 near the top of the opening of the male plug body 1 and the top of the opening of the male plug body 1 is less than the width of the threaded sleeve 121, so as to ensure that the threaded sleeve 121 fully engages with the thread teeth 21 and improves the locking degree.

[0034] In some embodiments, such as Figure 3 As shown, the threaded sleeve 121 and the movable ring 122 are both sleeved on the outer wall of the male plug body 1. Two limiting blocks 123 are symmetrically arranged on the inner wall of the movable ring 122. Two limiting grooves 13 are symmetrically arranged on the outer wall of the male plug body 1. The limiting blocks 123 are slidably installed in the corresponding limiting grooves 13.

[0035] In this embodiment, to prevent the movable ring 122 on the first anti-loosening component 12 from rotating on the male plug body 1 and to allow only axial sliding, two limiting grooves 13 are symmetrically formed on the outer wall of the male plug body 1 along its axial direction. Simultaneously, two limiting blocks 123 are symmetrically fixed on the inner wall of the movable ring 122. These two limiting blocks 123 are slidably installed within their respective limiting grooves 13. This fit ensures that when the user pushes the first anti-loosening component 12, the movable ring 122 can only slide back and forth on the male plug body 1 along the direction of the limiting grooves 13, and cannot rotate circumferentially, while not affecting the rotation of the threaded sleeve 121.

[0036] In some embodiments, such as Figure 4 As shown, the mounting ring 221 is symmetrically provided with elastic locking rods 223 on its outer side, and the locking block 222 is provided at the other end of the elastic locking rod 223; the inner wall of the male plug body 1 is provided with a guide groove 14 that is adapted to the elastic locking rod 223, and the locking hole is provided at the other end of the guide groove 14.

[0037] In this embodiment, the second anti-loosening component 22 is a key component for achieving the second locking (clamp-locking), providing a quick and convenient pre-locking function. This component includes a mounting ring 221, with two elastic levers 223 (either metal or plastic) symmetrically fixed to the outer side of the mounting ring 221. Each lever 223 has a protruding locking block 222 fixed at its end away from the mounting ring 221. To facilitate the clamp-locking of the second anti-loosening component 22, two guide grooves 14 are symmetrically formed on the inner wall of the male plug body 1 to mate with the elastic levers 223. At the bottom of the guide grooves 14, i.e., the insertion end, a locking hole 11 is formed to mate with the locking block 222.

[0038] In some embodiments, such as Figure 4 As shown, the mounting ring 221 is provided with a first mounting hole 224, and the female socket body 2 is provided with a mounting groove 23 at one end. The mounting groove 23 is provided with a second mounting hole 231 that is adapted to the first mounting hole 224. The first mounting hole 224 and the second mounting hole 231 are fixedly connected by screws 225.

[0039] In this embodiment, to securely install the second anti-loosening component 22 onto the female socket body 2, an annular mounting groove 23 is provided on the insertion end face of the female socket body 2. The mounting ring 221 is precisely accommodated within this mounting groove 23. The mounting ring 221 has several first mounting holes 224. By passing a screw 225 through the first mounting holes 224 and screwing it into the second mounting holes 231 of the female socket body 2, the mounting ring 221 and the entire second anti-loosening component 22 can be securely fixed to the female socket body 2. Therefore, the second anti-loosening component 22 can be easily disassembled and replaced if damaged.

[0040] In some embodiments, such as Figure 5 As shown, the male plug body 1 has a guide sleeve 15 surrounding the male plug pins 16 inside, and the guide sleeve 15 is adapted to the female socket pin hole seat 24 of the female socket body 2.

[0041] In this embodiment, the male plug body 1 is a hollow cylindrical structure, and a guide sleeve 15 is fixedly installed inside it. The function of the guide sleeve 15 is to provide guidance during the insertion process, ensuring that the pins of the male plug and the female socket can be accurately aligned and preventing damage.

[0042] As an example and not a limitation, the working process of this utility model is as follows:

[0043] When using, first align the male plug body 1 with the female socket body 2. During insertion, the guide sleeve 15 first enters the female socket body 2, serving as a preliminary alignment and guide.

[0044] First-stage locking: Continue pushing the male plug body 1 into the female socket body 2. During this process, the two elastic levers 223 on the female socket body 2 will enter the guide groove 14 on the inner wall of the male plug body 1 (serving as a foolproof design). As the insertion goes deeper, the locking block 222 will slide along the groove wall of the guide groove 14, causing the elastic levers 223 to elastically deform inward. When the male plug body 1 is fully inserted, the locking block 222 reaches the locking hole 11, and the elastic levers 223 return to their original shape due to their own elasticity, causing the locking block 222 to "click" into the locking hole 11. At this point, the first-stage locking is complete. This process provides clear tactile and audible feedback to confirm that the connection is in place. Furthermore, the locking force can prevent the connector from accidentally slipping out without external force, achieving initial anti-loosening.

[0045] Second-stage locking threaded fastening: After completing the snap-fit ​​locking, to achieve a higher level of anti-loosening, especially in environments with strong vibration, the user needs to perform a second-stage locking. The user pushes the entire first anti-loosening component 12 forward, allowing it to slide forward along the limiting groove 13 of the male plug body 1 until the front end of the threaded sleeve 121 contacts the female socket body 2. Then, the user manually rotates the threaded sleeve 121. Because the movable ring 122 is restricted from rotation by the cooperation of the limiting block 123 and the limiting groove 13, only the threaded sleeve 121 will rotate relative to the male plug body 1 and the movable ring 122. The internal thread of the threaded sleeve 121 will engage with the thread teeth 21 on the outer wall of the female socket body 2. Tightening the threaded sleeve 121 will generate a strong axial locking force, tightly pulling the male plug body 1 and the female socket body 2 together. At this point, the second-stage locking is complete.

[0046] Disassembly process: The operation sequence is reversed during disassembly. First, loosen the threaded sleeve 121 counterclockwise to disengage it from the thread 21. Then, pull the entire first anti-loosening assembly 12 backward along the male plug body 1. During the pull-back process, the limiting block 123 on the movable ring 122 will squeeze the end of the elastic locking rod 223, causing the locking block 222 to disengage from the locking hole 11, thus allowing the male plug body 1 to be pulled out of the female socket body 2.
