Description

Technical Field

[0001] This utility model belongs to the field of coaxial connector technology, and in particular relates to an anti-loosening and vibration-resistant radio frequency coaxial connector. Background Technology

[0002] A radio frequency coaxial connector is an electromechanical component used to transmit radio frequency / microwave signals. It is mainly used to connect coaxial transmission lines to realize signal transmission between devices or modules. The basic structure of a coaxial connector consists of three parts: an inner conductor, a dielectric, and an outer conductor. It also includes structural components, seals, etc.

[0003] Chinese patent CN208571146U discloses an RF coaxial connector, including a socket and an adapter. The outer conductor of the adapter's plug is flared to ensure that the socket and adapter plug connector can still provide sufficient positive pressure under extreme deviations. In addition, the small protrusion at the rear of the adapter's plug port ensures that the socket and adapter plug have a certain self-aligning capability under radial extreme deviations, ensuring that the plug is not damaged. Secondly, there is a sufficient gap between the inner conductor of the adapter plug and the inner conductor of the socket to ensure that the inner conductor of the plug will not be damaged under radial extreme deviations after the inner conductor of the plug is closed, which would lead to unreliable or no electrical contact. Compared with existing technologies, the RF coaxial connector can allow greater radial and axial offsets. However, in actual use, traditional connectors have defects such as easy loosening and unstable contact impedance in vibration environments, which affect their durability and lifespan, leaving room for improvement. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional connectors being prone to loosening and having unstable contact impedance in vibration environments, which affect their durability and lifespan. Therefore, this invention proposes an anti-loosening and vibration-resistant radio frequency coaxial connector.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an anti-loosening and vibration-resistant radio frequency coaxial connector, comprising:

[0006] The outer conductor sleeve has an inner cavity containing a pin, and a first external thread is provided at the bottom end of the outer conductor sleeve; the connector has a second external thread on its exterior, and the connector is connected to the inner thread of the outer conductor sleeve through the second external thread; the insert mechanism is connected to the bottom of the inner side of the outer conductor sleeve, and the insert mechanism abuts against the connector to enhance the lateral force applied to the pin.

[0007] As a further description of the above technical solution:

[0008] The inner thread of the outer conductor sleeve is provided with multiple guide grooves along the axis. Limiting components are connected in the guide grooves. The limiting components can be inserted and connected to the guide grooves, which facilitates quick replacement of the limiting components and improves the modular replacement effect.

[0009] As a further description of the above technical solution:

[0010] The limiting component includes a limiting seat, with a limiting spring connected to the inner cavity of the limiting seat. An abutment plate is connected to the opening side of the limiting seat corresponding to the position of the limiting spring. Through the designed limiting spring, the limiting seat can absorb the abutment energy of the abutment plate.

[0011] As a further description of the above technical solution:

[0012] The insert mechanism includes an elastic corrugated ring with a tapered cross-section. Multiple elastic inserts are connected around the top of the elastic corrugated ring along the axis. The elastic corrugated ring can improve the buffering and energy absorption effect.

[0013] As a further description of the above technical solution:

[0014] The inner side of the elastic insert is connected to multiple elastic blocks, and the cross-sectional shape of the elastic blocks is arc-shaped. By setting the elastic blocks, the abutment and support effect with the inner connector can be improved.

[0015] As a further description of the above technical solution:

[0016] The inner thread and the second outer thread of the outer conductor sleeve are both double-groove threads. The double-groove threads allow for easy and quick screwing in and positioning.

[0017] As a further description of the above technical solution:

[0018] The limiting spring has an arc-shaped cross-section, and one side of the limiting spring contacts the inner side of the abutment plate. The setting of the limiting spring can improve the support effect on the front abutment plate and facilitate full contact with the second external thread of the joint after the joint is screwed in.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, when the connector is connected to the outer conductor sleeve through the second external thread, the connector can be quickly coupled with the double-groove internal thread, which is beneficial to improve the quick connection effect. Through the designed insert mechanism, when the connector is screwed into the outer conductor sleeve through the thread, the inner conical surface of the elastic corrugated ring can fully abut against the end of the connector, effectively preventing the connector from loosening due to vibration, and effectively improving the vibration resistance and buffering capacity.

[0021] 2. In this utility model, the designed elastic insert can radially abut against the inner connector, which is beneficial to improve the impact resistance, improve the radial support stability of the inner pin of the outer conductor sleeve, resist mechanical vibration, solve the defects of traditional connectors that are easy to loosen and have unstable contact impedance in vibration environment, and extend service life.

[0031] The tapered elastic corrugated ring 601 can fully fit the inserted connector 2 through the tapered part of the front section of the elastic corrugated ring 601, which helps to further improve the abutment support effect.

[0032] Furthermore, the tail of connector 2 also has a limiting boss to maintain the effect of resisting mechanical vibration after locking;

[0033] Specifically: When connector 2 is connected to outer conductor sleeve 1 through the second external thread, connector 2 can be quickly coupled with double-groove internal thread 4, which is beneficial to improve the quick connection effect. In addition, through the designed insert mechanism 6, when connector 2 is screwed into outer conductor sleeve 1 through the thread, the inner conical surface of the elastic corrugated ring can fully abut against the end of connector 2, and the radial abutment force is improved by the cooperation of the outer elastic insert 602, which improves the impact resistance.

[0034] The RF coaxial connector model in this application can be customized as needed;

[0035] Multiple elastic blocks 603 are connected to the inner side of the elastic insert 602, and the cross-sectional shape of the elastic block 603 is arc-shaped;

[0036] Furthermore, through the designed elastic insert 602, the elastic insert 602 can radially abut against the inner connector 2, which is beneficial to improve the impact resistance, improve the radial support stability of the inner pin of the outer conductor sleeve 1, resist mechanical vibration, solve the defects of traditional connectors that are easy to loosen and have unstable contact impedance in vibration environment, and extend service life.

[0037] The inner thread 4 of the outer conductor sleeve 1 is provided with multiple guide grooves around the axis. The guide grooves are connected to a limit assembly 5.
