[0022] 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.

[0023] Please see Figure 1 and Figure 2 This utility model provides a technical solution for an RF coaxial connector: an RF coaxial connector including a connector 1, a female connector 2, a male connector 3 and a locking device 4. The output end of the connector 1 is connected to the female connector 2. The female connector 2 is connected to the male connector 3 through the locking device 4. The locking device 4 includes a locking device housing 41, a latching device 42 and a latching protrusion device 43. The latching device 42 is installed around the edge of the output end of the first housing 21 of the female connector 2. The latching protrusion device 43 is opened on the right side of the locking device housing 41 and is symmetrically arranged vertically.

[0024] The connector 1 includes a cable 11 and an insulator 12. The insulator 12 is uniformly attached to the surface of the cable 11, completely sealing and isolating the cable 11, ensuring the cable's airtightness, and preventing cable oxidation and leakage.

[0025] Please see Figure 3 The female connector 2 includes a first housing 21 and a first contact 22. The inner wall of the first housing 21 is fixedly connected to the outer surface of the insulator 12 in a surrounding manner. The first contact 22 is connected to the output end of the cable 11. The output end of the first contact 22 is smooth and rounded, presenting a spherical shape. While increasing the contact surface, the spherical surface prevents wear and damage caused by impact.

[0026] Please see Figure 4 The male connector 3 includes a second housing 31, a second insulator 32, and a second cable 33. The second cable 33 is completely sealed by the second insulator 32. The inner surface of the second housing 31 is fixedly connected to the second insulator 32, and the left side of the second housing 31 is fixedly connected to the locking device housing 41. When the input end of the second cable 33 contacts the first contact 22, it fits and seals to ensure the connection of the current signal.

[0027] Please see Figure 5The latching device 42 includes a fixed ring block 421, a movable hemispherical latching block 422, and a fixed hemispherical latching block 423. The fixed ring block 421 is installed on the left side of the right end of the first housing 21. The fixed hemispherical latching block 423 is fixedly installed on the rightmost side of the right end of the first housing 21. The movable hemispherical latching block 422 is slidably connected to the right side of the first housing 21 and is located between the fixed ring block 421 and the fixed hemispherical latching block 423. The three are at the same height to prevent the equipment from jamming due to height difference.

[0028] The latching protrusion device 43 includes a spring 431 and a triangular block 432. The triangular block 432 is installed in a slot inside the locking device housing 41 by the spring 431. Half of the triangular block 432 protrudes from the surface of the locking device housing 41. The left slope of the triangular block 432 is smooth, and the right straight plate surface is rough, which improves the latching ability and reduces the resistance to breakage.

[0029] When in use, the output end of the female connector 2 is inserted into the male connector 3. At the same time that the first contact 22 contacts the second cable 33, the fixed hemispherical block 423 at the front end of the latching device 42 pushes open the ramp of the triangular block 432, the spring 431 contracts, the movable hemispherical block 422 is pushed to the side of the fixed ring block 421, the spring pushes the triangular block 432, and the triangular block 432 is locked between the movable hemispherical block 422 and the fixed hemispherical block 423. At this time, the first contact 22 contacts the second cable 33.

[0030] After use, push the latching device 42 to the right again. Under the action of force, the triangular block 432 is squeezed between the fixed ring block 421 and the movable hemispherical latching block 422 as the spring compresses and contracts. Then pull out the latching device 42. Since the left end of the movable hemispherical latching block 422 is a smooth spherical surface, after the movable hemispherical latching block 422 is attached to the fixed hemispherical latching block 423, the triangular block 432 disengages from the movable hemispherical latching block 422 and the fixed hemispherical latching block 423, thus completing the disconnection of the locking device.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
