Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-shield coaxial quick push-pull self-locking connector. Background Technology

[0002] Coaxial push-pull self-locking connectors are quick-connect devices widely used in electronic equipment, communication systems, and medical devices. Their core feature is their coaxial structure, enabling rapid insertion and removal via a push-pull operation, and a self-locking function to ensure connection stability. However, most coaxial push-pull self-locking connectors on the market currently use an external spring locking mechanism. While this design is simple and low-cost, it has significant drawbacks in practical use. When users perform insertion and removal operations, significant friction and collision occur between the metal spring and the connector housing, resulting in a noticeable "clicking" sound. This noise problem is particularly prominent in special applications requiring quiet operation, such as medical testing equipment, recording studio audio equipment, and conference room audio-visual systems, often failing to meet users' needs for a low-noise operating environment. Furthermore, frequent metal friction accelerates connector wear, affecting product lifespan and connection reliability. Utility Model Content

[0003] The main purpose of this invention is to provide a high-shield coaxial quick-pull self-locking connector, which aims to eliminate the micro-explosion noise generated when connecting and disconnecting the connector, while maintaining a safe and tight locking fit.

[0004] To achieve the above objectives, this utility model proposes a high-shield coaxial quick-pull self-locking connector, comprising:

[0005] A socket assembly, the socket assembly including a socket housing and a first coaxial assembly, one end of the socket housing having a first cylindrical portion, the first coaxial assembly being disposed inside the first cylindrical portion, and the outer wall surface of the first cylindrical portion having a snap-fit ​​groove circumferentially provided.

[0006] A plug assembly includes a plug housing and a second coaxial assembly. One end of the plug housing is provided with a second cylindrical portion corresponding to the first cylindrical portion. The second coaxial assembly is disposed inside the second cylindrical portion. A snap-fit ​​cylinder is also provided around the second cylindrical portion. A snap-fit ​​strip is provided at the end of the snap-fit ​​cylinder. The first cylindrical portion can be inserted into the gap between the snap-fit ​​cylinder and the second cylindrical portion to connect the first coaxial assembly and the second coaxial assembly. The snap-fit ​​strip abuts against and is limited in the snap-fit ​​groove.

[0007] In one possible implementation, the plug assembly further includes a housing that covers the outside of the plug housing, and an abutment strip is provided on the inner wall of the housing corresponding to the snap-fit ​​strip. The housing is movable along the surface of the plug housing to allow the abutment strip to press against or move away from the snap-fit ​​strip.

[0008] In one possible implementation, an adjustment gap is formed between the outer shell and the plug housing, and a spring is provided in the adjustment gap, which can drive the abutment strip to press against the snap-fit ​​strip.

[0009] In one possible implementation, the snap-fit ​​cylinder has multiple circumferential cuts on its surface.

[0010] In one possible implementation, a sealing gasket is provided at the bottom of the gap between the snap-fit ​​cylinder and the second cylinder body.

[0011] This utility model's technical solution optimizes the snap-fit ​​cylinder structure, significantly reducing operating noise while maintaining high shielding performance and rapid insertion / removal characteristics; the addition of a circumferential elastic slit allows the snap-fit ​​cylinder to deform flexibly, avoiding the "clicking" sound of hard collisions between metal springs; and the sealing gasket further absorbs mechanical vibration noise through buffering and damping, making it particularly suitable for scenarios requiring silent operation, such as medical equipment and recording studios.

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] Reference Figures 1 to 3 This utility model proposes a high-shield coaxial quick-pull self-locking connector, including a socket assembly and a plug assembly. The socket assembly includes a socket housing 1 and a first coaxial assembly 2. One end of the socket housing 1 forms a first cylindrical portion 11, and the first coaxial assembly 2 is disposed inside the first cylindrical portion 11. A snap-fit ​​groove 12 is provided circumferentially on the outer wall surface of the first cylindrical portion 11. The plug assembly includes a plug housing 3 and a second coaxial assembly. One end of the plug housing 3 is provided with a second cylindrical portion 31 corresponding to the first cylindrical portion 11. The second coaxial assembly is disposed inside the second cylindrical portion 31. A snap-fit ​​tube 32 is also provided around the second cylindrical portion 31. A snap-fit ​​strip 33 is provided at the end of the snap-fit ​​tube 32. The first cylindrical portion 11 can be inserted into the gap between the snap-fit ​​tube 32 and the second cylindrical portion 31 to connect the first coaxial assembly 2 and the second coaxial assembly, and the snap-fit ​​strip 33 abuts against and is limited to the snap-fit ​​groove 12.

[0021] Understandably, one end of the socket housing 1 is provided with a first cylindrical portion 11, and the first coaxial assembly 2 is installed inside the first cylindrical portion 11 for transmitting signals or power. The snap-fit ​​groove 12 is a groove opened along the circumferential direction on the outer wall of the first cylindrical portion 11 for engaging and locking with the snap-fit ​​strip 33 of the plug assembly.

[0022] The plug housing 3 has a second cylindrical portion 31 corresponding to the first cylindrical portion 11 of the socket, which is used to mate with the insertion part of the socket. The second coaxial assembly is installed inside the second cylindrical portion 31 and mates with the first coaxial assembly 2 of the socket to realize signal or power transmission. The snap-fit ​​cylinder 32 is located around the second cylindrical portion 31, forming an annular space for the first cylindrical portion 11 of the socket to be inserted. The snap-fit ​​strip 33 is provided at the end of the snap-fit ​​cylinder 32 for engaging and locking with the snap-fit ​​groove 12 of the socket.

[0023] During insertion, the first cylindrical part 11 of the socket inserts into the gap between the snap-fit ​​sleeve 32 and the second cylindrical part 31 of the plug, bringing the first coaxial assembly 2 and the second coaxial assembly into contact and achieving electrical connection. Once the socket is fully inserted, the snap-fit ​​strip 33 on the plug engages with the snap-fit ​​groove 12 on the outer wall of the socket, forming a mechanical lock to prevent accidental dislodgement. This design enables quick insertion and removal, push-pull operation, convenient connection without rotation, and reduced noise.

[0024] Reference Figures 2 to 3 In one embodiment of the present invention, the plug assembly further includes a housing 5, which covers the outside of the plug housing 3. The inner wall of the housing 5 is provided with an abutment strip 51 corresponding to the snap-fit ​​strip 33. The housing 5 can move along the surface of the plug housing 3 so that the abutment strip 51 abuts against / moves away from the snap-fit ​​strip 33.

[0025] Understandably, the outer casing 5 is fitted over the outside of the plug housing 3 and can slide along the axial direction of the plug housing 3 to control the locking state. The abutment strip 51 is provided on the inner wall surface of the outer casing 5, and its position corresponds to the snap-fit ​​strip 33 of the plug housing 3.

[0026] When the plug is inserted into the socket, push the outer casing 5 forward to slide it, causing the abutment strip 51 of the outer casing 5 to press against the locking strip 33 of the plug housing 3. Since the locking strip 33 was already engaged in the locking groove 12 of the socket, the pressure of the abutment strip 51 makes the locking strip 33 more tightly embedded in the locking groove 12, enhancing the locking strength and preventing accidental loosening. When it is necessary to unplug the plug, slide the outer casing 5 backward to release the pressure of the abutment strip 51 on the locking strip 33. At this time, the engagement between the locking strip 33 and the locking groove 12 loosens, and the plug can be easily pulled out, achieving quick separation.

[0027] The above settings enhance locking reliability. The pressure of the abutment bar 51 makes the engagement bar 33 and the engagement groove 12 fit more tightly, making it suitable for vibration environments. Operation is more convenient, as locking / unlocking can be achieved simply by sliding the outer shell 5, without the need for additional tools or complicated operations.

[0028] Reference Figures 2 to 3 In one embodiment of this utility model, an adjustment gap 6 is formed between the outer shell 5 and the plug shell 3. A spring 61 is provided in the adjustment gap 6, and the spring 61 can drive the abutment strip 51 to press against the locking strip 33.

[0029] Understandably, an adjustment gap 6 is provided between the outer shell 5 and the plug shell 3. A compression spring 61 is installed in the adjustment gap 6. Under normal conditions, the spring 61 pushes the outer shell 5 forward, causing the abutment strip 51 to automatically press against the locking strip 33. When inserted, the socket cylinder is pushed in, which naturally compresses the spring 61. After it reaches the desired position, the spring 61 rebounds and automatically locks. When pulled out, the outer shell 5 must be manually pulled back to overcome the force of the spring 61 and release the lock before it can be separated.

[0030] Reference Figure 2 In one embodiment of this utility model, the surface of the snap-fit ​​cylinder 32 is provided with a plurality of circumferential cuts 34.

[0031] Understandably, the snap-fit ​​sleeve 32 significantly improves the smoothness of insertion and removal operations through the circumferential slits 34 design. Multiple longitudinal slits 34 are evenly spaced circumferentially on the surface of the snap-fit ​​sleeve 32. The number of slits 34 is typically 4-8, depending on the size, and the depth of the slits 34 extends to 2 / 3 of the length of the snap-fit ​​sleeve 32. During insertion, the slits 34 provide radial elasticity to the snap-fit ​​sleeve 32, reducing the required insertion force; after locking, the elastic flaps formed between the slits 34 provide uniform contact pressure; similarly, during removal, the slit structure reduces the operating force required for unlocking.

[0032] Reference Figure 3 In one embodiment of this utility model, a sealing gasket 7 is provided at the bottom of the gap between the snap-fit ​​cylinder 32 and the second cylinder part 31.

[0033] Understandably, the sealing gasket 7 fills the bottom of the gap between the snap-fit ​​cylinder 32 and the second cylinder part 31, forming a physical isolation barrier to prevent external dust, moisture, oil and other contaminants from entering the connector and improve the protection level; the elastic gasket can absorb the mechanical impact during insertion and removal, reduce hard collisions between metal parts, reduce wear and extend service life.

[0034] This utility model's technical solution optimizes the structure of the snap-fit ​​sleeve 32, significantly reducing operating noise while maintaining high shielding performance and rapid insertion / removal characteristics; the addition of a circumferential elastic slit 34 allows the snap-fit ​​sleeve 32 to deform flexibly, avoiding the "clicking" sound of hard collisions of metal springs; the sealing gasket 7 further absorbs mechanical vibration noise through buffering and damping, making it particularly suitable for scenarios requiring silent operation, such as medical equipment and recording studios.
