[0027] Example Reference Figures 1-7 This utility model provides a snap-fit ​​connection device for radio frequency units, which facilitates quick insertion and connection at the radio frequency unit interface and prevents loosening. It includes a main body assembly 100, comprising a female interface 200 fixed to one end of the main body assembly 100, a male connector 300 inserted into the end of the female interface 200, an unlocking component 400 screwed to the outer wall of the female interface 200, a retaining ring 500 fixed to the end of the unlocking component 400 at one end of the female interface 200, a retaining rod assembly 600 sliding on the outer wall of the male connector 300, a housing assembly 700 rotatably mounted on the end of the retaining rod assembly 600, the housing assembly 700 also sliding on the outer wall of the male connector 300, and an elastic component 800 fixed to the outer wall of the male connector 300 corresponding to the interior of the housing assembly 700. The elastic component 800 and the housing assembly... The 700 is fixed to the outer wall of the elastic component 800, corresponding to the opening of the housing component 700. By holding the housing component 700, the male connector 300 is inserted into the female interface 200. When the female interface 200 and the male connector 300 are connected, the housing component 700 pulls the elastic component 800, causing the housing component 700 to drive the locking rod component 600 to engage with the locking ring 500. Thus, the elastic component 800 can provide a fastening force during connection. When it is necessary to disconnect the female interface 200 and the male connector 300, by pushing the housing component 700, the elastic component 800 is pulled, causing the housing component 700 to drive the locking rod component 600 to touch the unlocking component 400. Then, the housing component 700 is pulled out, which allows the male connector 300 to disengage from the female interface. It has the function of quick installation and disassembly, and will not loosen during connection.

[0028] Specifically, the main component 100 includes a unit housing 101, flexible strips 102 fixed to the upper and lower sides of the unit housing 101, and heat sinks 103 fixed to the sides of the unit housing 101. In use, the flexible strips 102 on the upper and lower sides of the unit housing 101 can reduce damage to the internal radio frequency unit when bumped, and the heat sinks 103 on the sides of the unit housing 101 can enable the unit housing 101 to dissipate heat.

[0029] Furthermore, the unlocking component 400 includes an internally threaded tube 401 screwed to the outer wall of the female interface 200, a torsion member 402 fixed to the left end of the internally threaded tube 401, and a convex ring 403 sliding on the outer wall of the internally threaded tube 401. The convex ring 403 has a tapered surface 404 on the left side of the protruding end of the outer wall. In use, the torsion member 402 can be used by a torsion tool to drive the internally threaded tube 401 to rotate, so that the position of the internally threaded tube 401 can be adjusted on the outer wall of the female interface 200. The position can be adjusted according to the aging degree of the elastic component 800. The locking lever assembly 600 includes a movable ring 601 that slides on the outer wall of the male connector 300, and four latches 602 fixed to the left end of the movable ring 601. In use, when the movable ring 601 drives the latches 602 to engage with the retaining ring 500, a locking function is formed. When it is necessary to release the engagement, the movable ring 601 is pushed to move the latches 602 to the protruding ring 403. When the protruding ring 403 abuts against the torsion member 402, the protruding ring 403 cannot move, so the latches 602 can move to the outer wall of the protruding ring 403. At this time, the movable ring 601 is moved in the opposite direction to move the latches 602, so that the latches 602 can engage with the conical surface 404 and drive the protruding ring 403 to move until the protruding ring 403 moves to the retaining ring 500. At this time, the latches 602 will disengage from the conical surface 404 and the retaining ring 500.

[0030] Furthermore, the housing assembly 700 includes a housing 701 that rotates to the right of the movable ring 601, the housing 701 also slides on the outer wall of the male connector 300, the top of the housing 701 is provided with a slot 702, and the top of the housing 701 is provided with a limiting groove 703 on the left side of the slot 702.

[0031] Furthermore, the elastic assembly 800 includes a retaining ring 801 fixed to the outer wall of the male connector 300, and a spring 802 fixed between the retaining ring 801 and the housing 701. In use, the elastic assembly 800 provides elastic force to the lever assembly 600 by the spring 802 applying force to the housing 701.

[0032] Furthermore, the limiting component 900 includes a fixing rod 901 fixed to the top of the fixing ring 801 at the slot 702. The fixing rod 901 also slides within the slot 702. A nut 902 is screwed to the top of the fixing rod 901. The nut 902 and the limiting groove 703 are compatible. When the female interface 200 and the male connector 300 are connected, by twisting the thread 902 downward into the limiting groove 703, the housing component 700 cannot be pushed towards the female interface 200, thus completing the limiting function and giving it the function of preventing accidental contact.

[0033] During use, by holding the device housing 701 and inserting the male connector 300 into the female connector 200, when the female connector 200 and the male connector 300 are connected, the device housing 701 will compress the spring 802, causing the device housing 701 to drive the movable ring 601 and the buckle 602 to engage with the retaining ring 500, thus completing the quick connection. At this time, the elastic force of the spring 802 is applied to the device housing 701, the movable ring 601, and the buckle 602, and the buckle 602 engages with the retaining ring 500, thus providing a fastening force between the female connector 200 and the male connector 300. When the female connector 200 and the male connector 300 are connected, by twisting the thread 902 downward into the limiting groove 703, the housing assembly 700... If the pin cannot be pushed towards the female interface 200, it will not be able to complete the limited function and will have the function of preventing accidental contact. When it is necessary to release, by continuing to push the movable ring 601, the buckle 602 will be moved to the protruding ring 403. When the protruding ring 403 abuts against the torsion member 402, the protruding ring 403 cannot move, so the buckle 602 can be moved to the outer wall of the protruding ring 403. At this time, moving the movable ring 601 in the opposite direction will move the buckle 602, which will make the buckle 602 lock the conical surface 404 and move the protruding ring 403 until the protruding ring 403 moves to the retaining ring 500. At this time, the buckle 602 will disengage from the conical surface 404 and the retaining ring 500. It has the function of quick installation and disassembly, and will not loosen when connected.
