DETAILED DESCRIPTION

[0036] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0037] In addition, the elements in the present application are referred to as "fixed to" or "disposed on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0038] Referring to Figures 1-9 In the embodiments of the present application, a radio frequency coaxial connector with quick positioning and locking comprises:

[0039] A support plate 1 and a first connector 2 mounted on the support plate 1, the first connector 2 is provided with a first connector contact 3 arranged symmetrically, and a rotating sleeve 5 is rotatably mounted on the support plate 1 and sleeved on the first connector 2.

[0040] Further comprising:

[0041] Referring to Figures 1-4 , Figure 6 , Figure 9 A second connector 16 is pluggably mounted in the first connector 2, the second connector 16 is provided with a second connector contact 18 arranged symmetrically at the end, the first connector 2 is provided with a positioning and connecting assembly connected with the second connector 16, the positioning and connecting assembly can act when the second connector 16 is inserted into the first connector 2 to control the second connector contact 18 to move to the cooperating position with the first connector contact 3, the positioning and connecting assembly comprises an arc-shaped slot 201 and a first vertical slot 202 arranged symmetrically and opened in the first connector 2, the end of the arc-shaped slot 201 and the first vertical slot 202 are connected with each other, and the circumferential side wall of the second connector 16 is provided with a limiting column 17 which is slidably connected with the arc-shaped slot 201 and the first vertical slot 202.

[0042] In detail, the arc-shaped slot 201 is arranged in a circular arc shape. When the radio frequency coaxial connector is connected, the second connector 16 needs to be inserted into the first connector 2, and it is ensured that the second connector contact 18 can be smoothly inserted into the first connector contact 3. Therefore, when the second connector 16 is inserted into the first connector 2, the limiting column 17 will abut against the arc-shaped slot 201. At this time, a force is applied to the second connector 16 in the direction of the first connector 2. Under the action of the limiting column 17 and the arc-shaped slot 201, the second connector 16 can be guided to rotate in the direction of the first vertical slot 202 until the limiting column 17 is separated from the arc-shaped slot 201 and enters the first vertical slot 202. At this time, the second connector 16 is rotated to the required angle, and the second connector contact 18 is moved to the cooperating position with the first connector contact 3. At this time, the second connector 16 continues to move until the second connector contact 18 is completely inserted into the first connector contact 3.

[0043] Preferably, since the first connector contact 3 and the second connector contact 18 are both symmetrically arranged, when the limiting column 17 abuts against the arc-shaped slot 201 at any position, the limiting column 17 can be guided to enter the first vertical slot 202, so that the second connector contact 18 is moved to the same vertical plane as the first connector contact 3, thereby achieving the effect of positioning the second connector 16. It is prevented that the second connector contact 18 cannot enter the first connector contact 3 due to the insertion angle deviation of the second connector 16. It can also avoid the problem that the second connector contact 18 is deformed by external force when it is not completely cooperated with the first connector contact 3 due to the angle deviation of the second connector contact 18.

[0044] Please refer to Figures 3-6, a rotation locking mechanism arranged in the rotating sleeve 5 and connected with the positioning assembly, the rotation locking mechanism comprising a second vertical groove 501, a first spiral groove 502 and a first annular groove 503 symmetrically arranged on the inner wall of the rotating sleeve 5, two ends of the first spiral groove 502 being respectively connected with the second vertical groove 501 and the first annular groove 503, the limiting column 17 being slidingly fitted in the second vertical groove 501, the first spiral groove 502 and the first annular groove 503, the rotating sleeve 5 being provided with a following assembly connected with the first connector 2, wherein the following assembly comprises a second spiral groove 507 arranged on the inner wall of the rotating sleeve 5, the rotating sleeve 5 being slidingly provided with a sliding ring 6 slidingly connected with the first connector 2, the circumferential outer wall of the sliding ring 6 being provided with a protrusion 7, the protrusion 7 being slidingly fitted in the second spiral groove 507, the first connector 2 being sleeved with a second spring 8, two ends of the second spring 8 being respectively abutted with the second connector 16 and the sliding ring 6, the first connector 2 being provided with a guide structure connected with the sliding ring 6, the guide structure comprising a limiting groove 9 arranged on the inner wall of the sliding ring 6, the outer wall of the first connector 2 being provided with a limiting rod 10 slidingly fitted in the limiting groove 9.

[0045] It should be noted that the second vertical groove 501 extends through the end of the rotating sleeve 5, and in the initial state, the second spring 8 is in a compressed state, so that the sliding ring 6 is located at the end of the stroke away from the support plate 1, so that the protrusion 7 is located at the end of the stroke away from the support plate 1 on the side of the second spiral groove 507, and under the action of the second spring 8, the rotating sleeve 5 has a tendency to rotate towards the other side of the second spiral groove 507, at this time, the second vertical groove 501 is located at the same axial position as the first vertical groove 202, when the second connector 16 is inserted into the first connector 2, the limiting column 17 will slide along the track of the arc-shaped groove 201, until the limiting column 17 is separated from the arc-shaped groove 201 and enters the first vertical groove 202, because the connecting position of the arc-shaped groove 201 and the first vertical groove 202 is located above the end of the second vertical groove 501, therefore, when the limiting column 17 slides along the first vertical groove 202, it will smoothly enter the second vertical groove 501, when the limiting column 17 moves to the connecting position of the second vertical groove 501 and the first spiral groove 502, because the limiting column 17 is also in sliding connection with the first vertical groove 202, the second connector 16 will not rotate, so that the angle of the limiting column 17 will not deviate, therefore, when the limiting column 17 enters the first spiral groove 502, the rotating sleeve 5 will rotate, because the spiral directions of the first spiral groove 502 and the second spiral groove 507 are the same, therefore, the protrusion 7 will also slide along the second spiral groove 507, because the limiting rod 10 and the limiting groove 9 have a guiding effect, it ensures that the sliding ring 6 will not rotate with the rotating sleeve 5, under the action of the protrusion 7 and the second spiral groove 507, the sliding ring 6 slides along the length direction of the first connector 2, and compresses the second spring 8, when the limiting column 17 moves to the connecting position of the first spiral groove 502 and the first annular groove 503, the sliding ring 6 moves to the end of the stroke towards the support plate 1, at this time, the second spring 8 is elastically released, and drives the sliding ring 6 to move towards the initial position, to drive the protrusion 7 to slide in the second spiral groove 507, so that the rotating sleeve 5 rotates towards the initial angle, at this time, the limiting column 17 will enter the first annular groove 503, when the protrusion 7 returns to the end of the second spiral groove 507, the limiting column 17 moves to the end of the first annular groove 503 away from the first spiral groove 502, under the action of the second spring 8, the rotating sleeve 5 still has a tendency to rotate, thereby ensuring that the limiting column 17 is always located at the end of the first annular groove 503, to limit the movement of the second connector 16 in the vertical direction through the limiting column 17 and the first annular groove 503, to ensure that the second connector 16 will not be separated from the first connector 2.

[0046] Preferably, since in the process of docking the first connector 2 and the second connector 16, only the insertion of the second connector 16 into the first connector 2 is needed to complete the positioning of the second connector contact 18 and the locking of the position of the second connector 16, without the need for locking by screwing or screwing in after the completion of the connector, both the simple structure and the convenient and fast effect of the connector are ensured.

[0047] Please refer to Figures 1-5 , Figure 7 , Figure 8 , the first connector 2 is provided with a limiting mechanism connected with the rotating sleeve 5, the rotating locking mechanism can act when the positioning and connecting assembly moves to lock the position of the positioning and connecting assembly through the limiting mechanism, the limiting mechanism includes a sliding groove 203 opened on the outer wall of the first connector 2, a sliding block 11 is slidingly installed in the sliding groove 203, a third spring 12 is arranged in the sliding groove 203 and abuts against the sliding block 11, the rotating sleeve 5 is provided with a guide assembly connected with the sliding block 11, wherein the guide assembly includes a second annular groove 504, a third vertical groove 505 and a third annular groove 506 opened on the outer wall of the rotating sleeve 5, the two ends of the third vertical groove 505 are respectively connected with the second annular groove 504 and the third annular groove 506, the sliding block 11 is provided with a let-out structure, the let-out structure includes an inclined block 13 installed on the side wall of the sliding block 11, the inclined block 13 is provided with a supporting column 14, the supporting column 14 is slidingly connected with the second annular groove 504, the third vertical groove 505 and the third annular groove 506, and the end of the supporting column 14 is provided with an adjusting block 15.

[0048] Further, one side of the inclined block 13 is arranged in an inclined manner, and the other side is arranged in a vertical manner. The third vertical slot 505 has a size greater than the circumferential diameter of the supporting column 14. In the initial state, the third spring 12 is in a compressed state, so that the sliding block 11 is located at the end of the stroke of the sliding slot 203 away from the supporting plate 1. At this time, the inclined block 13 blocks the third annular slot 506, and the supporting column 14 is located at the connecting position of the third vertical slot 505 and the second annular slot 504. When it is necessary to connect the second connector 16, the limiting column 17 will enter the first vertical slot 202 through the arc-shaped slot 201. At the same time, the limiting column 17 will also slide along the second vertical slot 501 and the first helical slot 502. When the limiting column 17 enters the first helical slot 502, the rotating sleeve 5 will rotate, so that the supporting column 14 slides in the second annular slot 504. At the same time, under the action of the second helical slot 507 and the protrusion 7, the second spring 8 is compressed by the sliding ring 6, and the elastic potential energy of the second spring 8 is greater than that of the third spring 12. When the limiting column 17 is separated from the first helical slot 502 and enters the first annular slot 503, the rotating sleeve 5 rotates towards the initial angle under the action of the second spring 8, so as to control the limiting column 17 to enter the first annular slot 503. At the same time, the rotating sleeve 5 also controls the movement of the second annular slot 504, so that the distance between the third vertical slot 505 and the supporting column 14 becomes smaller. When the limiting column 17 has not yet abuts against the inclined surface of the inclined block 13, the third vertical slot 505 has already moved to the position matched with the supporting column 14. Therefore, when the limiting column 17 abuts against the inclined surface of the inclined block 13, the inclined block 13 will give way, and drive the sliding block 11 to slide along the sliding slot 203, so as to compress the third spring 12. The inclined block 13 also drives the supporting column 14 to enter the third vertical slot 505. When the limiting column 17 abuts against the end of the inclined block 13, the supporting column 14 has just completely entered the third annular slot 506. When the limiting column 17 is separated from the inclined surface of the inclined block 13, the limiting column 17 moves to the end of the stroke of the first annular slot 503. At this time, the third spring 12 is elastically released, so that the sliding block 11 is reset, and the inclined block 13 is also reset. The supporting column 14 returns to the connecting position of the second annular slot 504 and the third vertical slot 505 again. Under the action of the vertical surface of the inclined block 13, the movement of the limiting column 17 in the circumferential direction of the rotating sleeve 5 is limited, so as to ensure that the second connector 16 will not be separated from the first connector 2.

[0049] Preferably, under the double locking of the inclined block 13 and the first annular groove 503, when the adjusting block 15 is displaced by external force, the second spring 8 can still provide locking force, ensuring that the rotating sleeve 5 cannot rotate, so as to ensure that the second connector 16 cannot be displaced. If it is necessary to pull out the second connector 16, the first spring 4 is installed in the first connector 2, and when the second connector 16 is inserted into the first connector 2, the first spring 4 will be compressed. At this time, the adjusting block 15 can be manually controlled to move, so that the supporting column 14 enters the third annular groove 506 through the third vertical groove 505, so that the inclined block 13 is separated from the limiting column 17, and the rotating sleeve 5 is controlled to rotate, so that the supporting column 14 enters the third annular groove 506. Under the action of the third annular groove 506, it is ensured that the inclined block 13 cannot be reset, and the limiting column 17 will slide along the first annular groove 503. When the limiting column 17 moves to the position where the first annular groove 503 is connected with the first spiral groove 502, at this time, the first spring 4 is elastically released, and the second connector 16 is pushed out, so that the limiting column 17 slides along the first spiral groove 502 and the second vertical groove 501, so that the rotating sleeve 5 returns to the initial angle. Similarly, the supporting column 14 will be separated from the third annular groove 506, and will return to the initial position again under the action of the third spring 12. By controlling the rotation of the adjusting block 15 and the rotating sleeve 5, the unlocking effect can be achieved, and the first spring 4 has the effect of automatic ejection, so as to realize the effect of convenient disassembly and rapid removal of the second connector 16.

[0050] A connection method of a radio frequency coaxial connector with quick positioning and locking, comprising the following steps:

[0051] Step one: inserting the second connector 16 into the first connector 2, and under the action of the positioning and connecting assembly, moving the second connector contact 18 to the cooperating position with the first connector contact 3;

[0052] Step two: the positioning and connecting assembly also drives the rotating locking mechanism to move, and under the action of the rotating locking mechanism, the movement of the second connector 16 in the vertical direction is limited by the positioning and connecting assembly;

[0053] Step three: at the same time, under the action of the limiting mechanism, the rotation of the second connector 16 in the horizontal direction is limited by the positioning and connecting assembly, so as to control the second connector contact 18 to keep connected with the first connector contact 3 through the second connector 16.

[0054] It will be obvious to a person skilled in the art that the application is not limited to the details of the foregoing exemplary embodiments and can be implemented in other concrete forms without departing from the spirit or essential characteristics of the application.
