Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a connector that prevents detachment. Background Technology
[0002] A connector is a device or apparatus used to achieve electrical or signal connections, and is widely used in various electronic devices, systems, and networks. Its core function is to connect different circuits, components, or devices together through specific interface designs to enable the transmission of electrical energy, signals, or data.
[0003] However, most existing connectors still fall short in terms of connection stability and environmental adaptability. Many connectors are fixed by simple threaded structures. This type of connection is prone to loosening or even falling off when faced with vibration, impact or harsh environments, which in turn affects the normal operation of the equipment and the stability of signal transmission.
[0004] Therefore, there is a particular need for a connector that prevents detachment in order to solve the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of most existing connectors which are fixed by simple threaded structures and are prone to loosening and falling off under vibration, impact or harsh environments, affecting the normal operation of equipment and the stability of signal transmission, this utility model provides a connector that is resistant to falling off.
[0006] This utility model is achieved through the following technical means: a connector for preventing detachment, including a plug and a socket, wherein the core of the plug is inserted into the socket hole, and the two are stably connected. It also includes a mounting plate, a connecting plate, a wedge plate, a first spring, and a top block. The mounting plate is fixed to the outside of the plug, and the connecting plate is fixed to the outside of the socket and located directly behind the mounting plate. Two wedge plates are slidably disposed on the mounting plate, with the end away from the mounting plate having a hook-like structure and passing through the connecting plate to abut against its rear side, forming a limiting mechanism. Two first springs are symmetrically disposed on the mounting plate, with the two ends of each first spring fixedly connected to the mounting plate and the corresponding wedge plate, respectively. The first springs are high-strength springs. The top block is threaded on the outside of the plug, and its outer periphery has two symmetrically distributed semi-circular protrusions, which respectively contact the other ends of the two wedge plates.
[0007] Preferably, the plate also includes protrusions, with multiple protrusions divided into two groups, each group consisting of two protrusions arranged side by side and fixed to the other end of each wedge plate, and slidingly engaging with the corresponding track on the mounting plate.
[0008] Preferably, the device also includes limiting blocks, with multiple limiting blocks arranged in a circular array and fixed inside the plug. Multiple grooves, the same number as the limiting blocks, are arranged in a circular array and opened inside the socket. The limiting blocks and grooves correspond one-to-one for sliding engagement.
[0009] Preferably, a rubber ring is also included, which is fixed to the outside of the plug and forms a tight contact with the socket.
[0010] Preferably, the device also includes a rubber sleeve, a second spring, a rubber ring, guide rods, and a cover plate. The rubber ring is positioned between the plug and the socket and covers the connection between the plug and the socket from the circumferential direction. The rubber sleeve is fixed to the outer ring of the rubber ring by multiple second springs in a ring array and forms a sliding connection with the rubber ring. Multiple guide rods are evenly distributed along the two rings and fixed to both ends of the rubber sleeve. Each cover plate is inserted between multiple guide rods at the same end and forms a tight contact with the rubber sleeve.
[0011] Preferably, each guide rod has a ring of elastic material wrapped around its surface.
[0012] Beneficial effects: 1. Through the coordinated action of the mounting plate, connecting plate, wedge plate, first spring and top block, a stable connection mechanism is formed. This mechanism can achieve a stable connection between the plug and the socket, effectively preventing the plug from accidentally falling off the socket under vibration or external force, thereby ensuring the stability and safety of the electrical connection.
[0013] 2. Through the sliding snap-fit design of the limiting block and the groove, the plug is more securely fixed on the socket, effectively preventing wear on the core and socket caused by relative rotation during the plug-socket connection process, thereby extending the service life of the connector.
[0014] 3. The combination design of rubber sleeve, second spring, rubber ring, guide rod and cover plate provides double protection for the connection between plug and socket, effectively isolating external dust and moisture, and protecting the connection from corrosion and damage.

[0021] Example: A connector designed to prevent detachment, such as... Figures 1-4 As shown, the device includes a plug 1, a socket 2, limiting blocks 7, and a rubber ring 8. The core of the plug 1 is inserted into the socket hole of the socket 2, achieving a stable connection. Four limiting blocks 7 are arranged in a circular array and are bonded to the inside of the plug 1. Four grooves 71, the same number as the limiting blocks 7, are arranged in a circular array and are formed inside the socket 2. The limiting blocks 7 and grooves 71 are slidably engaged in a one-to-one correspondence, so that the plug 1 is limited to the socket 2. The rubber ring 8 is bonded to the outside of the plug 1 and forms a tight contact with the socket 2, providing a sealing protection. The device also includes a mounting plate 3, a connecting plate 4, wedge plates 5, a first spring 6, and a top block 9. The mounting plate 3 is bonded to the outside of the plug 1, and the connecting plate 4 is bonded to the outside of the socket 2 and is located directly behind the mounting plate 3. Two wedge plates 5 are vertically distributed and slidably disposed on the mounting plate 3. Their rear ends away from the mounting plate 3 have a hook-like structure and pass through the connecting plate 4, abutting its rear side to form a limiting mechanism, which securely limits the connecting plate 4 to the mounting plate 3. The limiting relationship between the connecting plate 4 and the mounting plate 3 indirectly limits the socket 2 to the plug 1, ensuring the stability of the connection. The four protrusions 51 are divided into two groups, with two protrusions in each group arranged side by side and bonded to the front end of each wedge plate 5. They slide and cooperate with the corresponding track on the mounting plate 3, thereby increasing the sliding contact area between the wedge plate 5 and the mounting plate 3 and improving the stability and smoothness of sliding. Two first springs 6 are symmetrically arranged on the mounting plate 3, with both ends of each first spring 6 fixedly connected to the mounting plate 3 and the corresponding wedge plate 5, respectively, providing necessary elastic support and restoring force for the wedge plate 5. The first springs 6 are strong springs. The top block 9 is threaded on the outside of the plug 1, and has two symmetrically distributed semi-circular protrusions on its outer periphery. These two semi-circular protrusions contact the front ends of the two wedge plates 5 respectively, providing positioning for the wedge plates 5. The last end of the thread on the outside of the plug 1 is kept on the same vertical plane as the rear side of the top block 9, ensuring that the top block 9 can remain stable in the initial position and can only slide forward.
[0022] like Figure 1 and Figure 5As shown, it also includes a rubber sleeve 10, a second spring 11, a rubber ring 12, guide rods 13, and a cover plate 14. The rubber ring 12 is placed between the plug 1 and the socket 2, covering the connection between the plug 1 and the socket 2 from the circumferential direction. The rubber sleeve 10 is bonded to the outer ring of the rubber ring 12 by eighteen second springs 11 arranged in a ring, forming a sliding connection with the rubber ring 12. The eight guide rods 13 are evenly distributed along the two rings and are bonded to the front and rear ends of the rubber sleeve 10 respectively. Each cover plate 14 is inserted between four guide rods 13 at the same end and forms a tight contact with the rubber sleeve 10, thereby sealing it off. The rubber ring 12 provides comprehensive protection for the connection between the plug 1 and the socket 2. Each guide rod 13 has a ring of elastic material, such as rubber or silicone, on its surface. During the installation of the cover plate 14, this elastic material is subjected to radial pressure and undergoes elastic deformation, i.e., it is compressed. When the cover plate 14 is fully inserted, the elastic material will gradually return to its original shape due to its inherent elastic restoring force. During this process, the elastic material will continuously apply a radial clamping force to the outer diameter of the guide rod 13. This clamping force can effectively prevent the cover plate 14 from slipping off along the axial direction of the guide rod 13.
[0023] When using connectors to connect devices, the wedge plate 5, under the abutment of the top block 9, always remains hooked to the connecting plate 4, preventing the plug 1 from accidentally falling off the socket 2. At the same time, under the double protective cover of the rubber sleeve 10 and the rubber ring 12, the connection between the plug 1 and the socket 2 is fully protected, avoiding the intrusion of external dust and moisture, thereby ensuring the stability and reliability of the connection.
[0024] When it is necessary to disassemble the connector, the operator shall follow these steps: First, remove the cover plate 14, then remove the rubber sleeve 10 to expose the connection between the plug 1 and the socket 2. Next, rotate the top block 9 clockwise to slide it forward and offset the wedge plate 5. At this time, press the wedge plate 5 inward to release the hook state with the connecting plate 4. During this process, the wedge plate 5 compresses the first spring 6. Then, pull the plug 1 to smoothly disengage its core from the socket 2's insertion hole. After disassembly, release the wedge plate 5. The first spring 6 returns to its original state and pushes the wedge plate 5 outward to return to its initial position for the next use.
