TECHNICAL FIELD
[0001] The utility model relates to the field of radio frequency connector, more specifically, it relates to a radio frequency connector with self locking structure. BACKGROUND
[0002] Radio frequency connector is an electronic component used for transmitting radio frequency signals, which plays a key role in wireless communication, radar, satellite communication and other fields. It is mainly composed of contact, insulator, shell and accessories, etc. It has low loss, high frequency characteristics and good impedance matching characteristics, which can ensure the integrity and stability of the radio frequency signal during transmission. There are many kinds of radio frequency connectors, such as SMA, N type, BNC, etc. Different types of radio frequency connectors have differences in interface size, performance index and application scene to adapt to different equipment and system requirements.
[0003] The traditional radio frequency connector has certain limitations in connection mechanism. During the connection operation, only the plug-in structure is used to realize the electrical connection, without additional fixed parts or devices for reinforcement. This design makes the radio frequency connector meet the basic signal transmission function requirements under normal use. However, once the external force is pulled, the connection between the connector and the connected object is easy to loosen due to the lack of effective fixing measures. Once loosened, it will not only cause unstable radio frequency signal transmission, signal attenuation, distortion and other problems, and even cause signal interruption. In order to make up for this defect, if the fixed parts are forcibly added, although the stability of the connection is enhanced to a certain extent, the risk of loosening is reduced, but new problems are brought. When subjected to external force, due to the existence of fixed parts, the external force cannot be buffered and dispersed through the appropriate displacement of the connector, and all the stress is concentrated in the radio frequency connector itself, which is easy to cause damage to the internal structural parts of the radio frequency connector such as contact, insulator, etc., affecting its normal use, and even the whole connector needs to be replaced, increasing the use cost and maintenance difficulty.
[0004] Therefore, in order to solve the above technical problems, the present application provides a radio frequency connector with self locking structure. UTILITY MODEL CONTENT

DETAILED DESCRIPTION
[0021] As Figures 1-4 shown, the present application provides a radio frequency connector with a self-locking structure, comprising a plug 1 and a socket 2, both sides of the plug 1 are connected with protrusions 4 through elastic expansion components 3, both sides of the interface 5 on the surface of the socket 2 are installed with frame-shaped plates 6 for the insertion of the protrusions 4, and buffer components 7 are installed in the frame-shaped plates 6.
[0022] When the plug 1 is connected with the socket 2, the protrusions 4 are pressed to the middle part in advance, so that the elastic expansion components 3 are compressed, the protrusions 4 can smoothly reach between the two frame-shaped plates 6, when the opening between the protrusions 4 and the frame-shaped plates 6 is aligned, the protrusions 4 are not blocked, the elastic expansion components 3 utilize their elasticity to drive the protrusions 4 on both sides to move to both sides and thus insert into the frame-shaped plates 6, and the frame-shaped plates 6 limit the protrusions 4, so as to achieve the purpose of self-locking between the plug 1 and the socket 2, avoid the radio frequency connector from loosening due to pulling (specifically, the plug 1 is pulled, causing the connection between the plug 1 and the socket 2 to loosen), and through the buffer component 7, the radio frequency connector can also be buffered when being pulled, so as to avoid damage to the radio frequency connector due to pulling, and the two protrusions 4 are pressed to move to the middle part again, so as to move the protrusions 4 out of the frame-shaped plates 6, at this time, the plug 1 is pulled, and the disassembly between the plug 1 and the socket 2 is completed.
[0023] The specific structure of the elastic stretching component 3 is as follows: the two sides of the plug 1 are provided with recesses 8, the elastic stretching component 3 comprises springs 301 fixed on the inner surfaces of the recesses 8, the heads of the springs 301 are connected with moving plates 302, the lugs 4 are fixed on the surfaces of the moving plates 302, the inner sides of the recesses 8 are fixedly connected with guide rails A 303, and the two sides of the moving plates 302 are slidably connected in the guide rails A 303 through sliding blocks A 304.
[0024] That is, when the two lugs 4 are moved to the middle part by extrusion, the lugs 4 drive the moving of the moving plates 302, so as to extrude the springs 301 between the moving plates 302 and the inner surfaces of the recesses 8, when the lugs 4 reach the middle part between the two frame-shaped plates 6, the lugs 4 are not blocked, the springs 301 reset the lugs 4 by using the elasticity, so as to be inserted into the frame-shaped plates 6, and when the moving plates 302 move, the moving plates 302 drive the moving of the sliding blocks A 304, the sliding blocks A 304 slide along the guide rails A 303, so as to maintain the linear movement of the moving plates 302.

[0027] Furthermore, the opposite surfaces of the frame-shaped plates 6 are fixedly connected with baffles 9, the baffles 9 avoid the lugs 4 from being pushed by the elastic stretching component 3 to abut against the elastic air cushions 703 without reaching the specified positions, i.e. the positions before the buffer plates 702.
