Description

Technical Field

[0001] The invention relates to the technical field of radio frequency connection, in particular to a radio frequency coaxial connector with rapid positioning and locking and a connection method thereof. Background Art

[0002] The main function of RF coaxial connectors is to serve as electrical connection or separation components of transmission lines, acting as a bridge. They are usually installed on cables or instruments to ensure continuous transmission and reception of signals, and are an indispensable key component in coaxial transmission systems.

[0003] RF coaxial connectors are widely used in communications, radar, television broadcasting, radio equipment and other fields to support the transmission and processing of high-frequency signals. With the development of technology, RF coaxial connectors are also moving towards miniaturization to meet the needs of more compact equipment.

[0004] Existing connector pairing connections are usually made by screwing on a nut or by quick-plug self-locking. However, nut connections usually require tools to assist, and may become loose over time. If quick-plug self-locking connections are used, they can usually only provide a single locking force. During use, they are easily affected by external forces, resulting in the failure of the locking force. Summary of the invention

A positioning connection component connected to the second connector is arranged on the first connector, and the positioning connection component can be actuated when the second connector is inserted into the first connector to control the second connector contact to move to a matching position with the first connector contact; A rotation locking mechanism is arranged in the rotating sleeve and connected to the positioning connection component. A limiting mechanism connected to the rotating sleeve is arranged on the first connector. The rotation locking mechanism can be activated when the positioning connection component moves to lock the position of the positioning connection component through the limiting mechanism.

[0007] As a further solution of the present invention: the positioning connection component includes an arc groove and a first vertical groove which are opened on the first connector and are symmetrically arranged, the arc groove and the end of the first vertical groove are connected to each other, and the circumferential side wall of the second connector is provided with a limiting column which slides with the arc groove and the first vertical groove.

[0008] As a further solution of the present invention: the rotation locking mechanism includes a second vertical groove, a first spiral groove, and a first annular groove which are symmetrically arranged on the inner wall of the rotating sleeve, the two ends of the first spiral groove are respectively connected to the ends of the second vertical groove and the first annular groove, the limiting column is slidably engaged with the second vertical groove, the first spiral groove, and the first annular groove, and a follower assembly connected to the first connector is arranged in the rotating sleeve.

[0009] As a further solution of the present invention: the follower assembly includes a second spiral groove provided on the inner wall of the rotating sleeve, a sliding ring slidably connected to the first connector is slidably installed in the rotating sleeve, a protrusion is provided on the circumferential outer wall of the sliding ring, and the protrusion is slidably engaged with the second spiral groove, a second spring is sleeved on the first connector, two ends of the second spring are respectively abutted against the second connector and the sliding ring, and a guide structure connected to the sliding ring is provided on the first connector.

[0010] As a further solution of the present invention: the guiding structure includes a limiting groove provided on the inner wall of the sliding ring, and the outer wall of the first connector is provided with a limiting rod slidably engaged with the limiting groove.

[0011] As a further solution of the present invention: the limiting mechanism includes a slide groove opened on the outer wall of the first connector, a sliding block is slidably installed in the slide groove, a third spring abutting against the sliding block is arranged in the slide groove, and a guide assembly connected to the sliding block is arranged on the rotating sleeve.

[0012] As a further solution of the present invention: the guide assembly includes a second annular groove, a second vertical groove, and a third annular groove opened on the outer wall of the rotating sleeve, the two ends of the second vertical groove are respectively connected to the ends of the second annular groove and the third annular groove, and a yield structure is provided on the sliding block.

[0013] As a further solution of the present invention: the giving way structure includes an inclined block installed on the side wall of the sliding block, a support column is arranged on the inclined block, the support column is slidably connected with the second annular groove, the second vertical groove and the third annular groove, and an adjustment block is arranged at the end of the support column.

[0014] A method for connecting a radio frequency coaxial connector with rapid positioning and locking, comprising the following steps: Step 1: insert the second connector into the first connector, and under the action of the positioning and connecting component, the second plug contact moves to a matching position with the first plug contact; Step 2: The positioning connection component also drives the rotation locking mechanism to move, and under the action of the rotation locking mechanism, the second connector is restricted from moving in the vertical direction through the positioning connection component; Step three: At the same time, under the action of the limiting mechanism, the second connector is limited to rotate in the horizontal direction through the positioning connection component, so as to control the second plug contact to maintain connection with the first plug contact through the second connector.

[0015] Compared with the prior art, the beneficial effect of the present invention is that the present application can control the rotation of the second connector through the positioning connection component to ensure that the second plug contact moves to a position that cooperates with the first plug contact. Specifically, when the second connector is inserted into the first connector, under the action of the positioning connection component, the second connector is controlled to rotate a certain angle to move the second plug contact to a position that cooperates with the first plug contact, ensuring that the two can be connected smoothly and avoiding the problem of deformation caused by external force when the second plug contact is not fully matched with the first plug contact due to angle deviation.

[0016] The position of the second connector can also be locked through the dual cooperation of the rotation locking mechanism and the limiting mechanism to ensure that the second connector contact will not be separated from the first connector contact. Specifically, under the action of the positioning connection component, the movement of the rotation locking mechanism is controlled to limit the movement of the second connector in the vertical direction. At the same time, under the action of the limiting mechanism, the rotation of the rotation locking mechanism is limited to ensure that the second connector will not be displaced, which will cause connection and disconnection problems.

[0017] Since during the docking process between the first connector and the second connector, the second connector contact can be positioned and the position of the second connector can be locked by simply inserting the second connector into the first connector, and there is no need to lock the second connector by bolting or screwing it in after the docking is completed, which ensures a simple structure and achieves the effect of convenient and quick docking.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0030] See also Figure 1 to Figure 9 In an embodiment of the present invention, a radio frequency coaxial connector with rapid positioning and locking includes: A support plate 1, and a first connector 2 mounted on the support plate 1, wherein the first connector 2 is provided with first plug contacts 3 which are symmetrically arranged, and a rotating sleeve 5 which is sleeved on the first connector 2 and is rotatably mounted on the support plate 1; Also includes: See also Figure 1-Figure 4 , Figure 6 , Fig. 9 , a second connector 16 is pluggable and installed in the first connector 2, and a symmetrically arranged second plug contact 18 is arranged at the end of the second connector 16. A positioning connection component connected to the second connector 16 is arranged on the first connector 2, and the positioning connection component can be actuated when the second connector 16 is inserted into the first connector 2 to control the second plug contact 18 to move to a matching position with the first plug contact 3. The positioning connection component includes an arc groove 201 and a first vertical groove 202 which are symmetrically arranged and opened on the first connector 2. The arc groove 201 is connected to the end of the first vertical groove 202, and the circumferential side wall of the second connector 16 is provided with a limiting column 17 that slidably cooperates with the arc groove 201 and the first vertical groove 202.

[0031] In detail, the arc groove 201 is arranged in an arc shape. When the RF coaxial connector is connected, the second connector 16 needs to be inserted into the first connector 2 and ensure that the second plug contact 18 can be smoothly inserted into the first plug contact 3. Therefore, when the second connector 16 is inserted into the first connector 2, the limiting column 17 will abut against the arc groove 201. At this time, a force toward the first connector 2 is applied to the second connector 16. Under the action of the limiting column 17 and the arc groove 201, the second connector 16 can be guided to rotate toward the first vertical groove 202 until the limiting column 17 disengages from the arc groove 201 and enters the first vertical groove 202. The second connector 16 rotates to the desired angle and controls the second plug contact 18 to move to a matching position with the first plug contact 3. At this time, the second connector 16 continues to move until the second plug contact 18 is completely inserted into the first plug contact 3.

[0032] Preferably, since the first plug contact 3 and the second plug contact 18 are symmetrically arranged, when the limit column 17 abuts against the arc groove 201 at any position, the limit column 17 can be guided to enter the first vertical groove 202, so that the second plug contact 18 moves to the same vertical plane as the first plug contact 3, thereby achieving the effect of positioning the second connector 16, preventing the second plug contact 18 from being unable to enter the first plug contact 3 due to the insertion angle deviation of the second connector 16, and also avoiding the problem of deformation caused by external force when the second plug contact 18 is not fully matched with the first plug contact 3 due to the angle deviation of the second connector 16.

[0033] See also Figure 3-6, a rotation locking mechanism is arranged in the rotating sleeve 5 and connected to the positioning connection component, the rotation locking mechanism includes a second vertical groove 501, a first spiral groove 502, and a first annular groove 503 which are symmetrically arranged on the inner wall of the rotating sleeve 5, the two ends of the first spiral groove 502 are respectively connected to the ends of the second vertical groove 501 and the first annular groove 503, the limiting column 17 is slidably engaged with the second vertical groove 501, the first spiral groove 502, and the first annular groove 503, and a follower component connected to the first connector 2 is arranged in the rotating sleeve 5, wherein the follower component ... the rotating sleeve 5 is provided with a follower component connected to the first connector 2, 5, a sliding ring 6 slidably connected to the first connector 2 is slidably installed in the rotating sleeve 5, a protrusion 7 is provided on the circumferential outer wall of the sliding ring 6, and the protrusion 7 is slidably engaged with the second spiral groove 507, a second spring 8 is sleeved on the first connector 2, and the two ends of the second spring 8 are respectively abutted against the second connector 16 and the sliding ring 6, and a guiding structure connected to the sliding ring 6 is provided on the first connector 2, and the guiding structure mentioned above includes a limiting groove 9 opened on the inner wall of the sliding ring 6, and a limiting rod 10 slidably engaged with the limiting groove 9 is provided on the outer wall of the first connector 2.

[0034] It should be noted that the second vertical groove 501 passes through the end of the rotating sleeve 5. 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 of the second spiral groove 507 away from the support plate 1. Under the action of the second spring 8, the rotating sleeve 5 has a tendency to rotate toward the other side of the second spiral groove 507. At this time, the second vertical groove 501 and the first vertical groove 202 are located at the same axial position. When the second connector 16 is inserted into the first connector 2, the limiting column 17 will slide along the trajectory of the arc groove 201 until the limiting column 17 is separated from the arc groove 2 01 and enters the first vertical groove 202, since the connecting position of the arc groove 201 and the first vertical groove 202 is located above the end of the second vertical groove 501, the limiting post 17 will smoothly enter the second vertical groove 501 when sliding along the first vertical groove 202. When the limiting post 17 moves to the connecting position of the second vertical groove 501 and the first spiral groove 502, since the limiting post 17 is still slidably connected to the first vertical groove 202, the second connector 16 will not rotate, so that the angle of the limiting post 17 will not deviate. Therefore, when the limiting post 17 enters the first spiral groove 502, the rotating sleeve 5 will rotate. 02 and the second spiral groove 507 have the same spiral direction, so the protrusion 7 will also slide along the second spiral groove 507. Since the limiting rod 10 and the limiting groove 9 have a guiding function, it is ensured 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 connection position between the first spiral groove 502 and the first annular groove 503, the sliding ring 6 moves to the end of the stroke toward the support plate 1. At this time, the second spring 8 is elastically released and drives the sliding ring 6 to move toward the initial position. To drive the protrusion 7 to slide in the second spiral groove 507, so that the rotating sleeve 5 rotates toward 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, so as to limit the second connector 16 from moving in the vertical direction through the limiting column 17 and the first annular groove 503, and ensure that the second connector 16 will not separate from the first connector 2.

[0035] Preferably, during the docking process between the first connector 2 and the second connector 16, the second connector contact 18 can be positioned and the position of the second connector 16 can be locked by only controlling the second connector 16 to be inserted into the first connector 2, without the need to lock it by bolts or screws after the docking is completed. This ensures a simple structure and achieves the effect of convenient and quick docking.

[0036] See also Figure 1-Figure 5 , Figure 7 , Figure 8 The first connector 2 is provided with a limiting mechanism connected to the rotating sleeve 5, and the rotating locking mechanism can be actuated when the positioning connection component moves, so as to lock the position of the positioning connection component through the limiting mechanism, and the limiting mechanism includes a slide groove 203 provided on the outer wall of the first connector 2, a sliding block 11 is slidably installed in the slide groove 203, and a third spring 12 abutting against the sliding block 11 is provided in the slide groove 203, and a guide component connected to the sliding block 11 is provided on the rotating sleeve 5, wherein the guide component includes a guide component provided on the rotating sleeve 5. The second annular groove 504, the third vertical groove 505, and the third annular groove 506 on the outer wall of the movable sleeve 5, the two ends of the third vertical groove 505 are respectively connected with the ends of the second annular groove 504 and the third annular groove 506, and the sliding block 11 is provided with a yielding structure. The yielding structure mentioned above includes an inclined block 13 installed on the side wall of the sliding block 11, and a support column 14 is provided on the inclined block 13. The support column 14 is slidably connected with the second annular groove 504, the third vertical groove 505, and the third annular groove 506, and an adjustment block 15 is provided at the end of the support column 14.

[0037] Furthermore, one side of the tilting block 13 is arranged in an inclined shape, and the other side is arranged in a vertical shape. The opening size of the third vertical groove 505 is larger than the circumferential diameter of the support 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 groove 203 away from the support plate 1. At this time, the tilting block 13 forms a barrier to the third annular groove 506, and the support column 14 is located at the connection position between the third vertical groove 505 and the second annular groove 504. When the second connector 16 needs to be connected, the limiting column 17 will enter the first vertical groove 202 through the arc groove 201. At the same time, the limiting The limiting post 17 will also slide along the second vertical groove 501 and the first spiral groove 502. When the limiting post 17 enters the first spiral groove 502, the rotating sleeve 5 will rotate, so that the supporting post 14 slides in the second annular groove 504. At the same time, under the action of the second spiral groove 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 the elastic potential energy of the third spring 12. When the limiting post 17 breaks away from the first spiral groove 502 and enters the first annular groove 503, under the action of the second spring 8, the rotating sleeve 5 rotates toward the initial angle to control The limiting column 17 enters the first annular groove 503. At the same time, the rotating sleeve 5 will also control the movement of the second annular groove 504, so that the distance between the third vertical groove 505 and the support column 14 becomes smaller, and when the limiting column 17 has not yet abutted against the inclined surface of the tilting block 13, the third vertical groove 505 moves to the matching position with the support column 14. Therefore, when the limiting column 17 moves to abut against the inclined surface of the tilting block 13, the tilting block 13 will give way and drive the sliding block 11 to slide along the sliding groove 203 to compress the third spring 12. The tilting block 13 still drives the support column 14 to enter the third vertical groove 505. When 17 abuts against the end of the tilting block 13, the support column 14 just completely enters the third annular groove 506. When the limiting column 17 separates from the inclined surface of the tilting block 13, the limiting column 17 moves to the end of the stroke of the first annular groove 503. At this time, the third spring 12 is elastically released, so that the sliding block 11 is reset to reset the tilting block 13, and the support column 14 returns to the connection position between the second annular groove 504 and the third vertical groove 505. Under the action of the vertical surface of the tilting block 13, the limiting column 17 is limited from moving in the circumferential direction of the rotating sleeve 5 to ensure that the second connector 16 will not be separated from the first connector 2.

[0038] Preferably, under the double locking of the tilting block 13 and the first annular groove 503, it can be ensured that when the adjusting block 15 is displaced by an external force, the second spring 8 can still provide a locking force to ensure that the rotating sleeve 5 does not rotate, so as to ensure that the second connector 16 does not displace. If it is necessary to pull out the second connector 16, the first spring 4 is also 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 support column 14 passes through the third vertical groove 505 and enters the third annular groove 506, so that the tilting block 13 is separated from the limiting column 17. At the same time, the rotating sleeve 5 is controlled to rotate so that the support column 14 enters the third annular groove 506. 06, to ensure that the tilting block 13 will not reset, the limiting column 17 will slide along the first annular groove 503, and 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 pushes out the second connector 16, 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 disengaged from the third annular groove 506 and, under the action of the third spring 12, return to the initial position again. The unlocking effect can be achieved by controlling the rotation of the adjusting block 15 and the rotating sleeve 5, and the first spring 4 has an automatic ejection effect, thereby achieving the effect of both convenient disassembly and quick removal of the second connector 16.

[0039] A method for connecting a radio frequency coaxial connector with rapid positioning and locking, comprising the following steps: Step 1: insert the second connector 16 into the first connector 2, and under the action of the positioning and connecting component, the second plug contact 18 moves to a matching position with the first plug contact 3; Step 2: The positioning connection component also drives the rotation locking mechanism to move. Under the action of the rotation locking mechanism, the second connector 16 is restricted from moving in the vertical direction through the positioning connection component; Step 3: At the same time, under the action of the limiting mechanism, the second connector 16 is limited to rotate in the horizontal direction through the positioning connection component, so as to control the second plug contact 18 to maintain connection with the first plug contact 3 through the second connector 16.
