[0023] like Figs. 1 to 3 As shown, an easy-to-install RF coaxial connector includes a housing 1. A connector 2 is fixedly installed on the bottom inner wall of the housing 1. A compression mating assembly 3 for limiting cable positioning is provided above the connector 2. An anti-loosening assembly 4 for controlling the operation of the compression mating assembly 3 is installed on the surface of the housing 1. A conductive tube 5 is fixedly inserted into the front of the housing 1. A dustproof assembly 6 for sealing the connection between the conductive tube 5 and the cable is provided on the front of the housing 1. More specifically, the coaxial cable is inserted into the housing 1 through the conductive tube 5, so that the end of the cable rests on the surface of the connector 2. The connector 2 and the cable make contact, establishing a circuit. Then, the compression mating assembly 3 is controlled by the anti-loosening assembly 4 to press the cable against the surface of the connector 2, fixing the connector 2 in place. The dustproof assembly 6 can block the gap between the cable and the conductive tube 5, preventing dust from passing through the conductive tube 5 and entering the interior of the housing 1, thereby ensuring the cleanliness of the connection between the cable and the connector 2.

[0024] The compression fitting assembly 3 includes a lead screw 301, which is rotatably connected to the top of the inner wall of the housing 1. An internally threaded tube 302 is threaded onto the surface of the lead screw 301, and a pressure block 303 is fixedly connected to the bottom end of the internally threaded tube 302. It should be noted that the lead screw 301 is rotated by the anti-loosening assembly 4, which in turn moves the internally threaded tube 302 under the action of the thread, thus pushing the pressure block 303 down. The pressure block 303 cooperates with the connecting seat 2 to compress and fix the cable.

[0025] The specifications of the pressure block 303 are adapted to the connecting seat 2, and the inner wall of the pressure block 303 is slidably connected to the surface of the connecting seat 2. More specifically, when the pressure block 303 moves, it will slide along the surface of the connecting seat 2, thereby preventing the pressure block 303 from rotating along with the internally threaded tube 302.

[0026] The anti-loosening component 4 includes a worm gear 401, which is rotatably connected to the housing 1. A knob 402 is fixedly connected to the front end of the worm gear 401. A worm wheel 403 is fixedly sleeved on the surface of the lead screw 301, and the worm wheel 403 meshes with the worm gear 401. It should be noted that by rotating the knob 402, the worm gear 401 is driven to rotate, causing the worm wheel 403 meshing with the worm gear 401 to rotate, thereby controlling the rotation of the lead screw 301. Furthermore, a self-locking mechanism is formed between the worm gear 401 and the worm wheel 403 to prevent the lead screw 301 from loosening.

[0027] The dustproof component 6 includes a mounting tube 601, which is fixedly connected to the front of the housing 1. A spring 602 is fixedly connected to the inner wall of the mounting tube 601. A connecting rod 603 is fixedly connected to the free end of the spring 602, and the connecting rod 603 is movably inserted into the mounting tube 601. An arc-shaped block 604 is fixedly connected to the end of the connecting rod 603, and a compression pad 605 is fixedly connected to the surface of the arc-shaped block 604. More specifically, by pulling the connecting rod 603, the spring 602 is stretched, causing the two arc-shaped blocks 604 to move away from each other. After the coaxial cable is inserted into the conductive tube 5, the connecting rod 603 is released. Under the elastic force of the spring 602, the connecting rod 603 will be pushed back to its original position, causing the arc-shaped block 604 and the compression pad 605 to move. The compression pad 605 will press against the surface of the cable, sealing the gap between the conductive tube 5 and the cable, preventing dust and impurities from entering the housing 1.

[0028] There are two arc-shaped blocks 604 and two compression pads 605, and the two arc-shaped blocks 604 and compression pads 605 are arranged symmetrically from left to right. It should be noted that by symmetrically arranging two arc-shaped blocks 604 and compression pads 605, the gaps between the cable and the conduit 5 can be completely sealed to prevent dust and impurities from entering.

[0029] In summary: When the coaxial cable is inserted into the housing 1 through the conduit 5, the cable end rests on the surface of the connector 2, and the connector 2 and the cable make contact, thus establishing a circuit. Subsequently, the anti-loosening component 4 controls the operation of the compression docking component 3, which compresses the cable onto the surface of the connector 2, securing the connector 2. The dustproof component 6 can block the gap between the cable and the conduit 5, preventing dust from passing through the conduit 5 and entering the interior of the housing 1, thereby ensuring the cleanliness of the connection between the cable and the connector 2. In use, this achieves the effect of facilitating quick connection and fixation of the cable, and after the connection is completed, it is not easy to loosen or detach, thus ensuring the stability of the cable connection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
