Directly combining two coaxial connectors will cause them to be locked and unable to be disassembled, affecting normal use. In this regard, the present application document proposes a coaxial connector to solve the above-mentioned problems. Summary of the invention

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] See also Figure 1-Figure 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.

[0019] A thread is provided at the front end of the inner wall of the outer sleeve 3 and is screwed together with the thread on the outer side of the inner sleeve 1. A push-down rod 8 is movably installed on the outer surface of the outer sleeve 3. The push-down 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.

[0020] 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.

[0021] A limiting ring 9 is provided on the outer surface of the receiving end 5, and the limiting ring 9 is provided with a limiting sleeve 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 guiding groove 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 side of the mounting ring 12, and the clamping strip 13 corresponds to the guiding groove 11. A reset spring 14 is provided on the front side of the mounting ring 12 at a position outside the clamping strip 13.

[0022] 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, and the mounting ring 12 is inserted from the top opening of the inner sleeve 1. The mounting ring 12 falls on the countersunk hole at one end of the receiving end 5 under the action of gravity.

[0023] 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 is limitedly sleeved with the rear sleeve 42, 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.

[0024] 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 .

[0025] At this time, when installing the matching ring 6 and the outer sleeve 3 as a whole, first place the buckle 62 at 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 shielding cover 2 will be driven to rotate synchronously during the screwing-in of the outer sleeve 3. As a result, during the screwing-in of the outer sleeve 3, the buckle 62 slides along the extension direction of the slide groove 15, so that the buckle 62 will not contact and rotate with the inner walls 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 of excessive friction on the top of the buckle 62 during frequent disassembly and assembly, resulting in the inability to achieve a normal snap-in effect.

[0026] See also Figure 1-Figure 6 Based on the first embodiment, the buckle 62 is engaged with the second clamping hole 16 and the first clamping 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.

[0027] Specifically, during the process of the outer sleeve 3 being screwed in, the bottom of the shielding cover 2 will contact the bottom of the mounting ring 12, and at the same time, 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 guiding 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 guiding 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 preventing the clamping strip 13 from being unable to extend normally from the inside of the guiding bevel groove 11 when the mounting ring 12 is squeezed.

[0028] As the outer sleeve 3 is tightened, the buckle 62 moves to the second clamping hole 16 and clamps, and the buckle 62 is also clamped with the first clamping hole 44, 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 groove 11 is shortened. Under this action, the clamping strip 13 extends from the inside of the guide bevel groove 11.

[0029] 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 of the outer sleeve 3 after tightening cannot be determined. When the buckle 62 is engaged with the second clamping hole 16, the first clamping hole 44 and the second clamping hole 16 can be located at corresponding positions by rotating the connecting sleeve 4, 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 screw-in 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 matching ring 6 to bear the axial tension, thereby ensuring the connection strength of the device.

[0030] 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 circle of the matching ring 6.

[0031] 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.

[0032] Specifically, the transmitting end 7 is inserted into the inner hole of the matching ring 6 so that the matching protrusion 20 is matched with the inner hole of the matching ring 6. Since the matching ring 6 is in a locked state and cannot rotate at this time, the transmitting end 7 as a whole cannot rotate after the matching protrusion 20 is matched with the matching ring 6. At the same time, the matching bevel groove 19 arranged at the front end of the outer surface of the transmitting end 7 will be matched and locked with the mounting ring 12 extending from the guide bevel groove 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, and after fixation, the data plug 18 is inserted into the inside of the data socket 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 socket 21 during the thread rotation and screwing-in matching process, causing surface wear and affecting data transmission quality, thereby improving the practicality of the device.

[0033] 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 push-down rod 8 is movably installed on the outer surface of the outer sleeve 3. The push-down 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 push-down rod 8 and the connecting rod 61 in a corresponding relationship. When the push-down rod 8 is pressed, the bottom of the push-down rod 8 contacts the connecting rod 61 and presses down, driving the buckle 62 to move downward.

[0034] Specifically, when it is necessary to quickly disassemble the device, it is only necessary to press the pressing rod 8, which presses the connecting rod 61 downward and drives the buckle 62 to move downward, so that the buckle 62 is released 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 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 groove 11 and released from the clamping connection with the matching bevel groove 19. At this time, the transmitting end 7 can be directly pulled out to complete the dismantling, thereby improving the convenience of using the device.

[0035] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
