Description
Technical Field
[0001] This utility model relates to the field of connectors, specifically a resilient contact anti-detachment connector. Background Technology
[0002] Electrical connectors are precision components used to reliably connect and disconnect circuits. They are widely used in industry, aerospace, and electronic equipment. They come in various forms, including plugs, sockets, and terminals. In industrial applications, electrical connectors require high protection levels and high-temperature resistance to ensure stable operation in harsh environments. Existing connectors typically rely on an integrated anti-detachment structure within the housing for locking, depending solely on the material's elasticity to ensure detachment prevention. However, when external force reaches a certain level, the connection can still break, causing power outages and posing a safety risk. Furthermore, the anti-detachment structure inevitably deteriorates after repeated insertions and removals due to the material's inherent lifespan, requiring complete connector replacement, which is uneconomical. Therefore, those skilled in the art have developed a resilient contact anti-detachment connector to address the problems described in the background section. Utility Model Content
[0003] The purpose of this invention is to provide a flexible contact anti-detachment connector to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: A flexible contact anti-detachment connector includes a male connector head, an anti-detachment sleeve, a female connector head, and an anti-detachment mounting ring. The anti-detachment sleeve is rotatably connected to the outer side of the male connector head. The top of the anti-detachment sleeve is horizontal to the top of the insertion rod on the male connector head. Two symmetrical clearance grooves are arranged on the inner side of the anti-detachment sleeve. A rotating groove is provided at the bottom of each clearance groove. Two arc-shaped receiving grooves are symmetrically arranged at the top of each rotating groove. Arc-shaped pressure blocks are slidably connected within each receiving groove. Each receiving groove has a symmetrically arranged [feature / feature] at its top. Two stud mounting holes are provided. Two guide studs are symmetrically arranged on the top of the arc-shaped pressure block via threaded connection. The guide studs are slidably connected to the stud mounting holes. A spring mounting hole is provided in the middle of the receiving groove. A compression spring is provided in the spring mounting hole. A connector female head is slidably connected to the top of the connector male head. An anti-detachment mounting ring is provided on the outer side of the connector female head. Two locking blocks are symmetrically arranged on the outer side of the anti-detachment mounting ring. The locking blocks are slidably connected to the clearance groove and rotatably connected to the rotating slide.
[0005] As a further embodiment of this utility model: a limiting ring is provided at the middle of the outer side of the male connector, and a locking ring is connected to the outer top of the male connector by a thread. The tail of the anti-drop sleeve is located between the limiting ring and the locking ring, and multiple locking holes are evenly distributed on the top of the locking ring.
[0006] As a further improvement of this utility model: a guide slope is provided between the bottom two ends of the arc-shaped pressure block and the side surface. When the arc-shaped pressure block is elastically acted upon by the compression spring and fits against the rotating slide groove, the guide slope coincides with the edge of the storage groove.
[0007] As a further improvement of this utility model, the top of the guide stud is provided with a slot.
[0008] As a further improvement of this utility model, the outer side of the anti-slip sleeve is evenly distributed with anti-slip texture.
[0009] As a further improvement of this utility model: the top outer side of the connector female head is provided with a connecting internal thread, and the anti-detachment mounting ring is threadedly connected to the connecting internal thread.
[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, an arc-shaped pressure block is slidably connected within the storage groove. Two guide studs are symmetrically arranged on the top of the arc-shaped pressure block via threaded connections. A spring mounting hole is provided in the middle of the storage groove, and a compression spring is installed inside the spring mounting hole. When the male connector and the female connector are slidably connected, the locking block is slidably connected to the clearance groove. Then, the anti-detachment sleeve is rotated, causing the locking block to slidably connect to the rotating slide. When the locking block contacts the arc-shaped pressure block, the compression spring is compressed, and the arc-shaped locking block enters the storage groove. Under the action of the compression spring, the arc-shaped locking block continuously presses down on the locking block, increasing the friction between the arc-shaped pressure block and the locking block, preventing the anti-detachment sleeve from rotating on its own, and improving the reliability of the anti-detachment mechanism.
[0011] 2. In this utility model, a limiting ring is provided at the middle of the outer side of the male connector, and a locking ring is connected to the outer top of the male connector by a thread. The tail of the anti-detachment sleeve is located between the limiting ring and the locking ring. The anti-detachment mounting ring is connected to the female connector by a thread. The key anti-detachment components can be quickly replaced, which is economical and easy to maintain. Attached Figure Description

[0014] 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.
[0015] Please see Figures 1-7In this embodiment of the utility model, the elastic contact anti-detachment connector includes a male connector 1, an anti-detachment sleeve 3, a female connector 2, and an anti-detachment mounting ring 4. The anti-detachment sleeve 3 is rotatably connected to the outer side of the male connector 1. The top end of the anti-detachment sleeve 3 is horizontal with the top end of the insertion rod on the male connector 1. Two clearance grooves 6 are symmetrically arranged on the inner side of the anti-detachment sleeve 3. A rotating slide groove 7 is provided at the bottom of the clearance groove 6. Two arc-shaped receiving grooves 8 are symmetrically arranged at the top of the rotating slide groove 7. An arc-shaped pressure block 9 is slidably connected in the receiving groove 8. Two stud mounting holes 11 are symmetrically arranged at the top of each receiving groove 8. Two guide studs 10 are symmetrically arranged on the top of the arc-shaped pressure block 9 through threaded connection. The guide studs 10 are connected to... The stud mounting hole 11 is a sliding connection. A spring mounting hole 15 is provided in the middle of the storage groove 8. A compression spring 13 is provided in the spring mounting hole 15. The top of the connector male head 1 is slidably connected to the connector female head 2. An anti-detachment mounting ring 4 is provided on the outside of the connector female head 2. Two locking blocks 19 are symmetrically arranged on the outside of the anti-detachment mounting ring 4. The locking blocks 19 are slidably connected to the clearance groove 6 and rotatably connected to the rotating slide 7. The rigid structure of the locking blocks 19 and the rotating slide 7 ensures that the anti-detachment sleeve 3 will not be disconnected due to external force after locking. The pressure of the compression spring 13 on the arc-shaped pressure block 9 increases the friction between the arc-shaped pressure block 9 and the locking blocks 19, so that the anti-detachment sleeve 3 cannot rotate on its own, thus improving the reliability of anti-detachment.
[0016] Among them, a limit ring 14 is provided at the middle of the outer side of the male connector 1, and a locking ring 12 is connected to the outer top of the male connector 1 by a thread. The tail of the anti-drop sleeve 3 is located between the limit ring 14 and the locking ring 12, which facilitates the replacement of the anti-drop sleeve 3. Multiple locking holes 16 are evenly distributed on the top of the locking ring 12, which facilitates the installation and removal of the locking ring 12 and makes it easy to use. Among them, the bottom ends of the arc-shaped pressure block 9 are provided with guide slopes 18 between the two sides. When the arc-shaped pressure block 9 is elastically acted by the compression spring 13 and fits against the rotating slide 7, the guide slopes 18 coincide with the edge of the storage groove 8, making the arc-shaped pressure block 9 and the locking block 19 rotate more smoothly. The top of the guide stud 10 is provided with a slot 17, which facilitates the installation of the guide stud 10 and makes it easy to use; Among them, the outer side of the anti-slip sleeve 3 is evenly distributed with anti-slip texture 5, which makes it easy to rotate the anti-slip sleeve 3 and to lock and release the anti-slip mounting ring 4. The connector female head 2 has an internal thread 20 on its top outer side. The anti-detachment mounting ring 4 is threadedly connected to the internal thread 20, which facilitates the replacement of the anti-detachment mounting ring 4 and is economical.
[0017] The working principle of this utility model is as follows: The anti-detachment sleeve 3 is slidably connected to the male connector 1, so that the tail of the anti-detachment sleeve 3 fits against the limiting ring 14. Then, using tweezers or other tools, the locking ring 12 is inserted into the locking hole 16, and the locking ring 12 is threadedly connected to the top outer side of the male connector 1, so that the anti-detachment sleeve 3 and the male connector 1 can be rotatably connected. The anti-detachment mounting ring 4 is threadedly connected to the female connector 2. When the male connector 1 and the female connector 2 are slidably connected, the anti-detachment sleeve 3 is rotated to make the clearance groove 6 slide with the locking block 19. When the locking block 19 moves to the rotating slide groove 7 at the bottom of the clearance groove 6, Rotating the anti-detachment sleeve 3 causes the locking block 19 to rotate and connect with the rotating slide 7. When the locking block 19 contacts the arc-shaped pressure block 9, the pressure spring 13 contracts under the action of the guide inclined surface 18, and the arc-shaped pressure block 9 enters the receiving groove 8. The locking block 19 moves to the bottom of the arc-shaped pressure block 9. Under the action of the pressure spring 13, the arc-shaped locking block 19 is always pressed down, which increases the friction between the arc-shaped pressure block 9 and the locking block 19, prevents the anti-detachment sleeve 3 from rotating, and improves the anti-detachment performance. The anti-detachment sleeve 3 and the anti-detachment mounting ring 4 are easy to replace. When damage occurs, the damaged parts can be quickly replaced without replacing the entire connector, which is economical.
[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
