Description

Technical Field

[0001] This utility model relates to the field of radio frequency coaxial connector technology, and more specifically to a small radio frequency coaxial connector. Background Technology

[0002] Currently, radio frequency coaxial connectors are generally considered to be components that are attached to cables or installed on instruments. As components that electrically connect or disconnect transmission lines, they belong to mechatronics products, and simply put, they mainly act as bridges.

[0003] However, the existing technologies mentioned above still have some drawbacks. The connection between the male and female connectors of some existing RF connectors is mostly achieved by using protrusions that form a mating fit as a latch. The connection between the male and female connectors is achieved by the elastic deformation of the latch. When the RF connector is small in size, the elastic deformation of the latch is not obvious. When the male and female connectors are disconnected, it takes a lot of force to pry open the latch, which is not convenient. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the present invention provides a small radio frequency coaxial connector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a male head and a female head. The female head has a female head protrusion, and an annular groove is provided on the outer wall of the female head protrusion. The male head has a male head protrusion, and a locking device is installed on the male head protrusion. The male head protrusion has a cavity for installing the locking device. The locking device includes an arc-shaped trigger and a locking wheel. The arc-shaped trigger has locking teeth, and the locking wheel has a locking wheel groove corresponding to the locking teeth, with the locking wheel groove close to the locking teeth. The locking wheel also has locking teeth corresponding to the annular groove, with the locking teeth close to the annular groove.

[0006] The present invention is further configured such that: a return spring A is provided in the cavity, the return spring A is connected to the bottom of the arc-shaped trigger, a chuck protrusion is provided at the tail end of the chuck, and a return spring B is provided at the rotation center of the chuck.

[0007] The present invention is further configured such that: the male protrusion is provided with an opening, and the opening communicates with the cavity.

[0008] The present invention is further configured such that the buckling device is symmetrically arranged with respect to the male head rotation center.

[0009] The present invention is further configured such that: the male protrusion is provided with an annular protrusion, and the female protrusion end face is provided with a corresponding annular groove.

[0010] The present invention is further configured such that a sealing ring is provided inside the annular groove.

[0011] In summary, this utility model has the following beneficial effects: The snap-fit ​​device ensures a secure and reliable connection between the male and female connectors. The engagement of the snap-fit ​​device with the annular groove of the female connector prevents the connector from loosening even when subjected to impacts or vibrations causing relative rotation, making it highly reliable. Disconnection is achieved simply by pushing the arc-shaped trigger extending from the bottom of the male connector, disrupting its support for the locking wheel. The locking wheel reverses under the spring force, disengaging the locking teeth from the annular groove, unlocking the snap-fit ​​device. The female connector can then be easily and conveniently disconnected by hand. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This embodiment discloses a small radio frequency coaxial connector, such as Figures 1 to 3As shown, the device includes a male connector 1 and a female connector 2. The female connector 2 has a female connector protrusion 21, and an annular groove is provided on the outer wall of the female connector protrusion 21. The male connector 1 has a male connector protrusion 11, and a locking device 3 is installed on the male connector protrusion 11. The male connector protrusion 11 has a cavity 111 for installing the locking device 3. The locking device 3 includes an arc-shaped trigger 31 and a locking wheel 32. The arc-shaped trigger 31 is provided with a locking tooth 311, and the locking wheel 32 is provided with a locking tooth 311. The locating wheel groove 322 is adapted to the locating tooth 311. When the latching device 3 is closed, the locating tooth 311 engages with the locating wheel groove 322. The arc-shaped trigger 31 provides a firm and reliable support to the locating wheel 32 through the engagement of the locating tooth 311 and the locating wheel groove 322, making the movement of the locating wheel 32 stable and not easily changed by impact or vibration. The locating wheel 32 is provided with a locating tooth 321 adapted to the annular groove 22, which is close to the annular groove 22. The engagement of the locating tooth 321 with the annular groove 22 allows the male head 1 and the female head 2 to be tightly connected together. When the male head 1 and the female head 2 encounter vibration and rotate relative to each other, the locating tooth 321 will rotate along the annular groove 22, and the connection between the male head 1 and the female head 2 will remain firm and reliable.

[0019] like Figures 3 to 4 As shown, the cavity 111 is equipped with a return spring A33, which is connected to the bottom of the arc-shaped trigger 31. Pulling the arc-shaped trigger 31 will disrupt its support for the retaining wheel 32, causing the latching device 3 to release. Under the elastic force of the return spring A33, the arc-shaped trigger 31 gains a closing force, making the connection of this novel design less prone to damage. The tail end of the retaining wheel 32 is provided with a retaining wheel protrusion 323, and the center of rotation of the retaining wheel 32 is provided with a return spring B. The placement of the return spring A33 and the return spring B allows the retaining wheel 32 to receive a counter-clockwise force, ensuring that when the latching device 3 is disconnected, the male head 1 and female head 2 are not obstructed by the retaining teeth 321, allowing them to smoothly enter the cavity 111 and complete the connection. In the disconnected state, the retaining wheel protrusion 323 extends under the elastic force of the return spring B, facilitating contact with the female head protrusion 211.

[0020] Further improvements include an opening 112 on the male protrusion 11, which connects to the cavity 111. This allows the locking tooth 311 to extend from the cavity 111, facilitating easy and convenient operation of the trigger to complete the opening mechanism of this novel device.

[0021] Furthermore, the latching device 3 is symmetrically arranged around the rotation center of the male head 1. This ensures that the latching force exerted by the latching device 3 is uniform when the device is closed, resulting in a reliable connection and a long service life.

[0022] Furthermore, the male protrusion 11 is provided with an annular protrusion 113, and the female protrusion 21 has a corresponding annular groove 211 on its end face. This allows the male head 1 and female head 2 to achieve a sealing surface through the cooperation of the annular protrusion and the annular groove 211, resulting in better protection for the internal connection and improving the reliability of the invention.

[0023] Furthermore, a sealing ring 212 is provided within the annular groove 211. The sealing ring 212 can improve the sealing performance of this invention. When encountering impact or vibration, the sealing ring 212 can absorb part of the impact and vibration, thus extending the service life of the invention.

[0024] Working principle of this utility model

[0025] The male connector 1 and the female connector 2 of this invention are connected so that the female connector protrusion 21 enters the cavity 111 of the male connector 1. The female connector protrusion 21 will contact and push the locating wheel protrusion 323 which is in a disconnected state, causing the locating wheel 32 to rotate. The locating teeth 321 provided on the locating wheel 32 will engage with the annular groove 22, so that this invention can obtain a reliable connection simply and conveniently, and will not loosen when encountering relative rotation caused by impact or vibration.

[0026] When disconnection is required, gently push the arc-shaped trigger 31 from the opening 112. The latching device 3 will release, the locking wheel 32 will reverse under the action of the return spring B, the locking tooth 321 will disengage from the annular groove 22, and at the same time the locking wheel protrusion 323 will slightly push out the female head protrusion 21, which will assist in the disconnection of this invention, making the disconnection of this invention very easy and simple.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
