Description

Technical Field

[0001] This utility model relates to the field of electrical connection components, and in particular to a connector with a self-locking and anti-loosening structure. Background Technology

[0002] The connector with a self-locking anti-loosening structure mainly solves the problem of traditional connectors being prone to loosening and poor contact during use, ensuring the reliability and stability of the connection. In many electronic, mechanical and electrical equipment, connectors are widely used to connect circuits and equipment. However, due to the influence of vibration, tension or external factors, the connection of traditional connectors may become loose, leading to equipment failure or performance degradation. In order to overcome this problem, a connector structure with a self-locking function has been developed.

[0003] Traditional connectors consist of a plug and a socket. The metal terminals of the plug and the metal terminals of the socket make contact to achieve electrical connection. The connector transmits signals or power through the plugging and unplugging process. Stable connection is usually ensured by spring pressure, crimping or threaded fastening. Traditional connectors have a certain locking mechanism to facilitate disassembly and replacement.

[0004] Traditional connectors, especially in industries such as automotive, aerospace, and electronic equipment, are subject to vibration or impact from the external environment during application. When connectors are exposed to vibration sources, the connection between the plug and socket is affected, leading to loosening or poor contact. Over time, this can result in signal loss, equipment failure, or short circuits. To address this issue, a connector with a self-locking anti-loosening structure is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connector with a self-locking and anti-loosening structure, which aims to improve the problem of unstable connection of connectors in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connector with a self-locking and anti-loosening structure includes a connecting plate, an interface fixedly connected to one side of the connecting plate, a fixing plate one fixedly connected to the inner wall of the interface, a connecting post slidably connected to the inner wall of the fixing plate one, a triangular apex fixedly connected to one end of the connecting post, a spring sleeved on the outer wall of the connecting post, a pull rod fixedly connected to the other end of the connecting post, a pull handle fixedly connected to one end of the pull rod, a fixing plate two fixedly connected to one side of the inner wall of the interface, and a protective component provided on the top of the interface.

[0008] As a further description of the above technical solution:

[0009] The protective component includes a fixed block, a rotating rod is fixedly connected to the inner wall of the fixed block, and two connecting blocks are rotatably connected to the outer wall of the rotating rod;

[0010] As a further description of the above technical solution:

[0011] A protective cover is fixedly connected to the top of the two connecting blocks, and a plug is slidably connected to the inner wall of the interface;

[0012] As a further description of the above technical solution:

[0013] A fixing ring is fixedly connected to one side of the plug, and a transmission line is fixedly connected to the inner wall of the fixing ring;

[0014] As a further description of the above technical solution:

[0015] The outer wall of the triangular apex is slidably connected to the inner wall of the interface, and the outer wall of the pull rod is slidably connected to the inner wall of the second fixing plate;

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to one side of the triangular apex, and the other end of the spring is fixedly connected to one side of the fixing plate.

[0018] As a further description of the above technical solution:

[0019] The bottom of the fixing block is fixedly connected to the top of the interface, and the outer wall of the triangular top contactes the outer groove of the plug;

[0020] As a further description of the above technical solution:

[0021] The plug has grooves on both sides, and the inner wall of the protective cover is in contact with the outer wall of the transmission line.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by inserting the plug into the interior of the interface, the outer wall of the plug can push the two triangular fins to both sides, thereby compressing the spring and generating elastic force. When the plug is fully inserted into the interior of the interface, the spring can release the elastic force, thereby pushing the triangular fins to slide forward. The triangular fins can engage with the groove on the outer wall of the plug, thus achieving self-locking between the interface and the plug. When the interface and the plug need to be disassembled, by pulling the handle, the movement of the handle can drive the pull rod to move, and the movement of the pull rod can drive the connecting post and the triangular fins to move, thereby separating the plug from the interface, greatly improving the practicality and convenience of the device.

[0024] 2. In this utility model, by rotating the protective cover, the protective cover can drive the two connecting blocks to rotate on the fixed block, thereby achieving effective protection of the plug and interface connection part. When the plug and interface are connected, the protective cover can smoothly cover the connection point of the plug and interface, forming a protective barrier to prevent external objects or accidental collisions from damaging the plug and interface, thereby avoiding interference from the external environment, preventing dust, moisture and other factors from adversely affecting the equipment, extending the service life of the equipment, improving the reliability of the equipment, and ensuring long-term stable operation.

[0032] 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.

[0033] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a connector with a self-locking anti-loosening structure, including a connecting plate 1. An interface 2 is fixedly connected to one side of the connecting plate 1. The interface 2 serves as the main connecting component, responsible for connecting with subsequent equipment and providing a stable contact point. A fixing plate 3 is fixedly connected to the inner wall of the interface 2, which serves to reinforce and ensure the stability of the inner wall of the interface 2, preventing loosening after long-term use. A connecting post 4 is slidably connected to the inner wall of the fixing plate 3. The connecting post 4 can slide along the inner wall of the interface 2, which helps to flexibly adapt to different connection requirements and enhance the practicality of the connector. A triangular head 5 is fixedly connected to one end of the connecting post 4. The triangular head 5 can play a guiding role during insertion, making the connection more accurate and avoiding poor contact of the plug 10.

[0034] A spring 6 is fitted on the outer wall of the connecting post 4. The function of the spring 6 is to provide elastic force to ensure that the connecting post 4 can move freely during insertion and removal, and to effectively restore its position through rebound force, thereby enhancing the self-locking function of the device. A pull rod 7 is fixedly connected to the other end of the connecting post 4. The pull rod 7 can improve the convenience of operation. A handle 9 is fixedly connected to one end of the pull rod 7. A fixing plate 8 is fixedly connected to the inner wall of one side of the interface 2. A protective component is provided on the top of the interface 2.

[0035] Reference Figures 2 to 4 The protective component includes a fixing block 13, which provides support and a stable foundation to ensure that the component does not shift during use. A rotating rod 14 is fixedly connected to the inner wall of the fixing block 13. The rotating rod 14 allows the protective component to rotate or adjust at a specific angle to adapt to different usage requirements. Two connecting blocks 15 are rotatably connected to the outer wall of the rotating rod 14. The connecting blocks 15 allow the protective component to be more securely connected to subsequent components. A protective cover 16 is fixedly connected to the top of the two connecting blocks 15. The main function of the protective cover 16 is to protect the components of the equipment and prevent external physical damage or dust intrusion. A plug 10 is slidably connected to the inner wall of the interface 2. The plug 10 is made easier to install or remove by sliding. A fixing ring 11 is fixedly connected to one side of the plug 10. A transmission line 12 is fixedly connected to the inner wall of the fixing ring 11.

[0036] Working principle: By inserting the plug 10 into the interface 2, the outer wall of the plug 10 pushes the two triangular heads 5 to the sides, thereby compressing the spring 6 and generating elastic force. When the plug 10 is fully inserted into the interface 2, the spring 6 releases the elastic force, thereby pushing the triangular heads 5 forward. The triangular heads 5 can engage with the groove on the outer wall of the plug 10, thus achieving self-locking between the interface 2 and the plug 10. When the interface 2 and the plug 10 need to be disassembled, by pulling the handle 9, the movement of the handle 9 can drive the pull rod 7 to move. The movement of the pull rod 7 can drive the connecting post 4 and the triangular heads 5 to move, thereby separating the plug 10 from the interface 2, greatly improving the practicality and convenience of the device.

[0037] By rotating the protective cover 16, the two connecting blocks 15 can rotate on the fixed block 13, thereby effectively protecting the connection between the plug 10 and the interface 2. When the plug 10 and the interface 2 are connected, the protective cover 16 can smoothly cover the connection between the plug 10 and the interface 2, forming a protective barrier to prevent damage to the plug 10 and the interface 2 from external objects or accidental collisions. This avoids interference from the external environment, prevents dust, moisture and other factors from adversely affecting the equipment, extends the service life of the equipment, improves the reliability of the equipment, and ensures stable operation for a long time.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
