Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector that prevents accidental disconnection. Background Technology

[0002] Connectors, also known as plugs or sockets, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, upon contact, can transmit information or current; hence, they are called connectors.

[0003] Existing connectors often suffer from accidental disconnection due to the lack of self-locking function, causing signal interruption and losses to enterprises. Furthermore, the lack of anti-accidental disconnection function makes them prone to accidental disconnection or insertion by non-professionals, resulting in poor electrical connection stability.

[0004] To address this, we propose a connector designed to prevent accidental disconnection. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a connector that prevents accidental disconnection.

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

[0007] An anti-accidental disconnect connector includes a socket, a groove on one side of the socket, a toggle lever movably installed inside the groove, the toggle lever being L-shaped, a slot on one side of the socket, two clips movably installed inside the slot, a plug engaging inside the clips, a first wire installed on the side of the socket away from the plug, a second wire fixedly installed on the side of the plug away from the socket, and an anti-accidental disconnect component installed inside the socket.

[0008] As a further improvement of this utility model: the anti-misoperation component includes a sliding groove, the socket has a sliding groove inside, a convex shaft is slidably connected inside the sliding groove, and two push-pull rods are rotatably connected to the outside of the convex shaft.

[0009] As a further embodiment of this utility model: the two ends of the two push-pull rods away from the convex shaft are respectively rotatably connected to two clamps, and the two clamps are rotatably connected to the socket.

[0010] As a further improvement of this utility model: two slots are provided on the side of the two clamps that are close to each other, and two tenons are engaged and connected inside the two slots. The two tenons are respectively fixedly installed on both sides of the plug.

[0011] As a further embodiment of this utility model: a sliding groove is provided on the upper surface of the toggle lever, the sliding groove is slidably connected to the convex shaft, and the end of the toggle lever away from the convex shaft is rotatably connected to the socket.

[0012] As a further improvement of this utility model: a fixing ring is fixedly installed on the side of the toggle lever away from the push-pull lever, and a spring is installed inside the fixing ring.

[0013] As a further improvement of this utility model: a connecting ring is installed at the end of the spring away from the fixed ring, and the connecting ring is fixedly connected to the socket.

[0014] Compared with the prior art, the present invention provides a connector that prevents accidental disconnection, which has the following advantages:

[0015] 1. The core innovation of this utility model's anti-misplug connector lies in its ingeniously designed linkage locking structure. Through a mechanical transmission system composed of a toggle lever, a convex shaft, and a push-pull lever, a secure connection between the plug and socket can be achieved with a single hand. When the plug is inserted into the slot, the locking mechanism automatically engages with the latches on both sides of the plug under the action of the push-pull lever, forming a four-point locking structure that greatly enhances tensile strength. Particularly noteworthy is the continuous tension provided by the spring through the fixing ring and connecting ring, ensuring the toggle lever remains in the locked position, effectively preventing loosening due to vibration or accidental pulling. This elastic locking mechanism is particularly important in vibration environments such as aerospace and industrial automation, ensuring continuous and stable operation of equipment under harsh conditions.

[0016] 2. This utility model's anti-accidental disconnection component design fully considers the balance between ease of operation and reliability. The L-shaped lever is ergonomically designed, providing a comfortable grip and operating lever arm, allowing for easy operation even while wearing gloves. The sliding connection between the sliding groove and the convex shaft converts the rotational motion of the lever into the linear motion of the push-pull rod, achieving effective force transmission and direction conversion. Furthermore, the engagement design of the slot and the tenon adopts a progressive ramp structure, making the insertion process smoother and providing clear feedback upon completion. This design has significant advantages in scenarios with extremely high requirements for connection stability, such as medical equipment and rail transportation, effectively reducing safety risks caused by misoperation or accidental disconnection.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0025] Example: A connector to prevent accidental unplugging, such as Figures 1-4 As shown, the device includes a socket 1, a groove 2 on one side of the socket 1, a lever 3 movably installed inside the groove 2, the lever 3 being L-shaped, a slot 4 on one side of the socket 1, two clips 5 movably installed inside the slot 4, a plug 6 engaging inside the clips 5, a wire 7 installed on the side of the socket 1 away from the plug 6, a second wire 8 fixedly installed on the side of the plug 6 away from the socket 1, and an anti-accidental disconnection component 9 installed inside the socket 1.

[0026] like Figures 1-4As shown, the anti-misoperation component 9 includes a slide groove 10. The slide groove 10 is located inside the socket 1. A convex shaft 11 is slidably connected inside the slide groove 10. Two push-pull rods 12 are rotatably connected to the outside of the convex shaft 11. The two ends of the two push-pull rods 12 away from the convex shaft 11 are rotatably connected to two clamps 5. The two clamps 5 are rotatably connected to the socket 1. Two slots 13 are located on the side of the two clamps 5 that are close to each other. Two tenons 14 are engaged inside the two slots 13. The two tenons 14 are fixedly installed on both sides of the plug 6. A sliding groove 15 is located on the upper surface of the toggle rod 3. The sliding groove 15 is slidably connected to the convex shaft 11. The end of the toggle rod 3 away from the convex shaft 11 is rotatably connected to the socket 1. A fixing ring 16 is fixedly installed on the side of the toggle rod 3 away from the push-pull rod 12. A fixing ring 16 is installed inside the fixing ring 16. There is a spring 17, and a connecting ring 18 is installed at the end of the spring 17 away from the fixing ring 16. The connecting ring 18 is fixedly connected to the socket 1. The plug 6 is inserted into the slot 4. The locking tenon 14 pushes the locking device 5 to open outward. At this time, the actuating rod 3 moves in conjunction with the locking device 5. The convex shaft 11 is located at the bottom of the sliding groove 15. Locking stage: When the plug 6 is fully inserted, the actuating rod 3 is raised. It drives the convex shaft 11 to slide down along the sliding groove 10 through the sliding groove 15. The push-pull rod 12 pushes the locking device 5 to rotate inward, so that the slot 13 and the locking tenon 14 are fully engaged. At the same time, the spring 17 is compressed to generate elastic potential energy and maintain the locked state. Unlocking stage: Press down the actuating rod 3, the convex shaft 11 slides up, and the push-pull rod 12 drives the locking device 5 to open outward, releasing the locking of the locking tenon 14. At this time, the plug 6 can be pulled out smoothly.

[0027] Working principle: The working process of this anti-misoperation connector can be divided into three stages: insertion, locking, and unlocking. Insertion stage: The plug 6 is inserted into the slot 4, and the locking tenon 14 pushes the locking device 5 to open outward. At this time, the actuating rod 3 moves in conjunction with the locking device 5, and the convex shaft 11 is located at the bottom of the sliding groove 15. Locking stage: When the plug 6 is fully inserted, the actuating rod 3 is raised, and the convex shaft 11 is driven to slide down the sliding groove 10 through the sliding groove 15. The push-pull rod 12 then pushes the locking device 5 to rotate inward, so that the slot 13 and the locking tenon 14 are fully engaged. At the same time, the spring 17 is compressed to generate elastic potential energy to maintain the locked state. Unlocking stage: Press down the actuating rod 3, the convex shaft 11 slides up, and the push-pull rod 12 drives the locking device 5 to open outward, releasing the locking of the locking tenon 14. At this time, the plug 6 can be pulled out smoothly. The whole process is achieved through mechanical linkage, without the need for additional tools, and is simple to operate and highly reliable.
