DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] See also Figures 1-6 In one embodiment of the present invention, a coaxial connector includes an inner sleeve 1, a shielding cover 2 is sleeved on the inner side of the inner sleeve 1, an outer sleeve 3 is sleeved on the outer side of the inner sleeve 1 through a threaded fixing sleeve, a connecting sleeve 4 is sleeved on the outer side of the inner sleeve 1 near the front end, a receiving end 5 is movably sleeved on the inner side of the connecting sleeve 4 near the front end, a mating ring 6 is sleeved on the inner side of the outer sleeve 3 near the end, a transmitting end 7 is sleeved on the inner side of the mating ring 6 near the end, a connecting rod 61 is fixedly installed on the front side of the mating ring 6, a buckle 62 is provided at the front end of the connecting rod 61, and a push plate 63 is provided at the top of the connecting rod 61 near the end.

[0025] The front end of the inner wall of the outer sleeve 3 is provided with a thread and is tightened with the thread on the outside of the inner sleeve 1. A downward pressure rod 8 is movably installed on the outer surface of the outer sleeve 3. The downward pressure rod 8 is in contact with the buckle 62. A polygonal hole is provided on the inner wall of the outer sleeve 3 near the end, and the polygonal hole cooperates with the mating ring 6.

[0026] Specifically, when in use, the matching ring 6 needs to be inserted into the end of the outer sleeve 3 so that the matching ring 6 and the outer sleeve 3 form a whole.

[0027] A limiting ring 9 is provided on the outer surface of the receiving end 5, and the limiting ring 9 is limitedly sleeved on the inner wall of the connecting sleeve 4 near the front end. A ratchet 10 is provided on the outer surface of the receiving end 5 near the limiting ring 9. A countersunk hole is provided at one end of the receiving end 5, and a guide bevel 11 is provided at the bottom of the countersunk hole. A mounting ring 12 is provided inside the countersunk hole at one end of the receiving end 5, and a clamping strip 13 is provided on the front of the mounting ring 12, which corresponds to the guide bevel 11. A reset spring 14 is provided on the front of the mounting ring 12 at a position outside the clamping strip 13.

[0028] Specifically, before placing the mounting ring 12, the inner sleeve 1, the connecting sleeve 4 and the receiving end 5 are placed in a vertical direction, with the inner sleeve 1 facing upward and the receiving end 5 facing downward. The mounting ring 12 is inserted from the top opening of the inner sleeve 1, and the mounting ring 12 falls on the countersunk hole at one end of the receiving end 5 under the action of gravity.

[0029] The connecting sleeve 4 includes a front sleeve 41 and a rear sleeve 42. The inner wall of the front sleeve 41 is provided with an annular ratchet 43, and the outer surface of the rear sleeve 42 is provided with a first clamping hole 44. The annular ratchet 43 corresponds to the ratchet 10, and the first clamping hole 44 is clamped with the buckle 62. The front end of the inner sleeve 1 and the rear sleeve 42 are limitedly sleeved, and the inner wall of the shielding cover 2 is provided with a slide groove 15. The slide groove 15 is provided with a second clamping hole 16 near the front end, and the outer surface of the shielding cover 2 is provided with an annular push plate 17 near the end. The rotation direction of the front sleeve 41 is opposite to the screwing direction of the outer sleeve 3.

[0030] Specifically, after the mounting ring 12 is placed, the shielding cover 2 is also placed from the top opening of the inner sleeve 1 so that the bottom of the shielding cover 2 contacts the top of the mounting ring 12 .

[0031] At this time, when installing the mating ring 6 and the outer sleeve 3 as a whole, first place the buckle 62 in the position corresponding to the slide groove 15, and then rotate the outer sleeve 3 so that the inner thread of the outer sleeve 3 is screwed in and matched with the outer thread of the inner sleeve 1. In this process, since the buckle 62 is in a state of matching with the slide groove 15, the outer sleeve 3 will drive the shielding cover 2 to rotate synchronously during the screwing in process, which makes the buckle 62 slide along the extension direction of the slide groove 15 during the screwing in process of the outer sleeve 3, so that the buckle 62 will not contact and rotate with the inner wall of the shielding cover 2 and the inner sleeve 1 under the action of the rotation and screwing in of the outer sleeve 3, thereby avoiding the problem that the buckle 62 top is unable to achieve the normal snapping effect due to excessive friction during frequent disassembly and assembly.

[0032] See also Figures 1-6 Based on the first embodiment, the buckle 62 is engaged with the second card hole 16 and the first card hole 44, the push plate 63 is in contact with the annular push plate 17, and the front end of the shielding cover 2 and the back of the mounting ring 12 are both provided with bevel teeth and cooperate with each other.

[0033] Specifically, during the process of screwing in the outer sleeve 3, the bottom of the shielding cover 2 will contact the bottom of the mounting ring 12, and the front end of the shielding cover 2 and the back of the mounting ring 12 are provided with bevel teeth and cooperate with each other, so that the shielding cover 2 will drive the mounting ring 12 to rotate when it rotates. If the mounting ring 12 is placed and the clamping strip 13 is not in a corresponding state with the guide bevel groove 11, the shielding cover 2 will drive the mounting ring 12 to rotate at a certain angle, so that the clamping strip 13 corresponds to and cooperates with the guide bevel groove 11. At this time, the mounting ring 12 can no longer rotate, thereby ensuring that the mounting ring 12 and the clamping strip 13 are in the correct position, and avoiding the clamping strip 13 from being unable to extend normally from the inside of the guide bevel groove 11 when the mounting ring 12 is squeezed.

[0034] As the outer sleeve 3 is tightened, the buckle 62 moves to the second clamping hole 16 and clamps, and the buckle 62 is clamped with the first clamping hole 44 at the same time, and the push plate 63 will press against the annular push plate 17 and drive the front end of the shielding cover 2 to squeeze the mounting ring 12, so that the distance between the mounting ring 12 and the guide bevel 11 is shortened. Under this action, the clamping strip 13 extends from the inside of the guide bevel 11.

[0035] Since the inner sleeve 1 and the outer sleeve 3 are tightened by threads, the tightening force each time is different, and as metal fatigue occurs, the positions of the buckle 62 and the second clamping hole 16 after the outer sleeve 3 is tightened cannot be determined. When the buckle 62 is engaged with the second clamping hole 16, the connecting sleeve 4 can be rotated so that the first clamping hole 44 and the second clamping hole 16 are in corresponding positions, so that the buckle 62 can correspond to the first clamping hole 44, and the annular ratchet 43 corresponds to the ratchet 10 and can only rotate in one direction. At the same time, the rotation direction of the connecting sleeve 4 is opposite to the screwing direction of the outer sleeve 3, so that after the buckle 62 is engaged with the second clamping hole 16 and the first clamping hole 44, the inner sleeve 1 can no longer be affected by the rotational torque. At the same time, the threaded tightening effect of the inner sleeve 1 and the outer sleeve 3 can also improve the strength of the mating ring 6 in bearing the axial tension, thereby ensuring the connection strength of the device.

[0036] See also Figure 1-Figure 5 Based on the first embodiment, a signal access terminal is provided at the end of the transmitting terminal 7, a groove is provided at the front end of the transmitting terminal 7, and a data plug 18 is provided inside the groove. A matching bevel 19 is provided on the outer surface of the transmitting terminal 7 near the front end, and the matching bevel 19 is engaged with the card strip 13. A matching protrusion 20 is provided on the outer surface of the transmitting terminal 7 near the end, and the matching protrusion 20 is engaged with the inner ring of the matching ring 6.

[0037] The front end of the receiving end 5 is provided with a signal output end, the inner cavity of the receiving end 5 is provided with a data jack 21, and the data plug 18 cooperates with the data jack 21 to realize data transmission.

[0038] Specifically, the transmitting end 7 is inserted into the inner hole of the mating ring 6 so that the mating protrusion 20 is mated with the inner hole of the mating ring 6. Since the mating ring 6 is in a locked state and cannot rotate at this time, the transmitting end 7 as a whole cannot rotate after the mating protrusion 20 is mated with the mating ring 6. At the same time, the mating bevel 19 provided on the front end of the outer surface of the transmitting end 7 will be mated and locked with the mounting ring 12 extending from the guide bevel 11 after insertion. At this time, the transmitting end 7 is fixed and its axial and circumferential directions are limited, so that the transmitting end 7 is fully fixed. After fixation, the data plug 18 is inserted into the interior of the data jack 21 to realize data transmission. This connection method can avoid the problem of reduced torque bearing capacity caused by traditional threaded connection, and also avoids the problem of weak axial tensile bearing capacity of plug-in card connection. In addition, it also avoids the problem of excessive friction between the data plug 18 and the data jack 21 during the thread rotation and screwing-in process, causing surface wear and affecting data transmission quality, thereby improving the practicality of the device.

[0039] See also Figure 1-Figure 5In another embodiment of the present invention, a thread is provided at the front end of the inner wall of the outer sleeve 3 and is tightened with the thread on the outer side of the inner sleeve 1. A downward pressure rod 8 is movably installed on the outer surface of the outer sleeve 3. The downward pressure rod 8 contacts the buckle 62. A polygonal hole is provided on the inner wall of the outer sleeve 3 near the end. The polygonal hole cooperates with the matching ring 6 to keep the downward pressure rod 8 and the connecting rod 61 in a corresponding relationship. When the downward pressure rod 8 is pressed, the bottom of the downward pressure rod 8 contacts the connecting rod 61 and presses down, driving the buckle 62 to move downward.

[0040] Specifically, when it is necessary to quickly disassemble the device, it is only necessary to press the down-pressing rod 8, which presses the connecting rod 61 downward and drives the buckle 62 to move downward, so that the buckle 62 is disengaged from the second clamping hole 16 and the first clamping hole 44, and the shielding cover 2 that has lost the limit of the buckle 62 is also released from the locked state at the same time. At this time, the mounting ring 12 is reset under the elastic potential energy stored in the reset spring 14, and the clamping strip 13 is reset to the inside of the guide bevel 11 and is disengaged from the matching bevel 19. At this time, the transmitting end 7 can be directly pulled out to complete the disassembly, thereby improving the convenience of using the device.

[0041] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
