DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 making creative work are within the scope of protection of the present invention.

[0038] The present invention will be further described below in conjunction with the embodiments.

[0039] See also Figures 1 to 12A radio frequency coaxial connector of the present embodiment includes a connector 10 and a connector 20. A protective unit for protecting the interface between the connector 10 and the connector 20 is disposed on the outside of the connector 10. The protective unit includes a wrapping mechanism 30 for protecting the connector 10 and the connector 20. A traction unit connected to the connector 20 is disposed inside the connector 10. The traction unit includes a docking mechanism 60 for pulling the connector 20.

[0040] See also Figure 1 and Figure 2 The wrapping mechanism 30 includes two cover plates 301 symmetrically arranged on the outside of the connector 10, and two groups of first connecting rods 303 are symmetrically rotatably connected between the two cover plates 301. The number of first connecting rods 303 in each group is two, and the two first connecting rods 303 in the same group are rotatably connected through the second connecting rod 304. The same end of the two second connecting rods 304 is fixedly connected with a sliding sleeve 305, and the sliding sleeve 305 is slidably sleeved on the outside of the connector 10.

[0041] See also Figure 1 and Figure 2 The wrapping mechanism 30 also includes a rectangular block 302 symmetrically fixedly connected to the outside of the connector 10 and the connector 2 20, and the top and bottom of the rectangular block 302 are slidably connected with guide rods 306, and the guide rods 306 at the top of the rectangular block 302 and the guide rods 306 at the bottom of the rectangular block 302 are staggered from each other, and the two guide rods 306 are fixedly connected to the two cover plates 301 respectively.

[0042] A cavity for accommodating the rectangular block 302 is formed on one side of the two cover plates 301 that are close to each other, and the cavity matches the two rectangular blocks 302 .

[0043] During specific operation, after the connectors are docked together, the two cover plates 301 are directly pressed to bring the two cover plates 301 closer to each other. When the two cover plates 301 are fully buckled together, the rectangular blocks 302 outside the connector 10 and the connector 20 are completely wrapped inside the two cover plates 301. In the process of the two cover plates 301 approaching each other, the guide rod 306 slides along the rectangular block 302 outside the connector 10. At the same time, the two cover plates 301 also push the sliding sleeve 305 to move outside the connector 10 through the first connecting rod 303 and the second connecting rod 304. The guide rod 306 and the sliding sleeve 305 are used to provide support for the cover plate 301, so that the cover plate 301 is more stable during movement. The two ends of the connector are restricted inside the cover plate 301, which can share part of the pulling force, thereby reducing the pulling force between the connectors and improving the connection stability of the connectors.

[0044] See also Figure 1 , Figure 3 , Figure 3 and Figure 4The protection unit also includes a locking mechanism 40 for fixing the two cover plates 301 together. The locking mechanism 40 includes outer shells 401 fixedly connected to the sides of the two cover plates 301 respectively. A mounting block 402 is fixedly connected to the inside of each outer shell 401. A plug 403 is fixedly connected to one end of each mounting block 402, and the plug 403 extends to the outside of the outer shell 401. A socket 407 matching the plug 403 is opened on the side of the outer shell 401.

[0045] The locking mechanism 40 also includes a first accommodating groove 404 opened inside the mounting block 402, and a semicircular arc block 405 is rotatably connected inside the first accommodating groove 404. A first spring 406 is arranged inside the first accommodating groove 404, and one end of the first spring 406 is fixedly connected to the arc surface of the arc block 405, and the other end of the first spring 406 is fixedly connected to the mounting block 402.

[0046] During specific operation, the plugs 403 on the sides of the two cover plates 301 are inserted into the sockets 407 of another locking mechanism 40. At this time, the plug 403 first pushes the semicircular arc block 405 to rotate, so that the arc block 405 is completely rotated into the first accommodating groove 404. When the arc block 405 rotates, the arc block 405 squeezes the first spring 406, and then the plug 403 is completely inserted into the socket 407. At this time, the arc block 405 rotates in the opposite direction under the elastic force of the first spring 406. The two semicircular arc blocks 405 are staggered with each other so that the two plugs 403 are fixed to each other in the outer shell 401. The locking mechanism 40 can make the two cover plates 301 tightly combined, and it is not easy to separate even when pulled or impacted from the outside, thereby enhancing the mechanical strength of the entire package. In a vibration or impact environment, the locking mechanism 40 can maintain the stability of the cover plate 301.

[0047] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The protection unit also includes a sealing mechanism 50 for improving the sealing performance of the gap between the two cover plates 301. The sealing mechanism 50 includes telescopic grooves 502 respectively opened on the surfaces of the two cover plates 301. A telescopic pad 501 is slidably connected in each telescopic groove 502. An arc-shaped slide groove 504 is opened through the side wall of the telescopic groove 502. A lever 505 is slidably connected in the slide groove 504. The lever 505 is located at the bottom of the telescopic pad 501. The lever 505 extends from the slide groove 504 to the other side of the cover plate 301, and the lever 505 extends to the inside of the outer shell 401. The lever 505 is fixedly connected to the end away from the telescopic groove 502 with a lever 503. The middle part of the lever 503 is rotatably connected to the outer shell 401 through a connecting shaft. The telescopic pad 501 is made of silicone material. The telescopic pad 501 is arranged in a hole shape along the opening of the cover plate 301, and the two telescopic pads 501 are respectively formed into a concave shape and a convex shape on the side close to each other.

[0048] During specific operation, when the plug 403 is fully inserted into the socket 407, the plug 403 first contacts one end of the lever 503, causing the lever 503 to rotate, and the rotating lever 503 drives the lever 505 to rotate upward in the slide groove 504. At this time, the lever 505 pushes the telescopic pad 501 upward from the telescopic groove 502, thereby engaging the telescopic pads 501 between the two cover plates 301 with each other. The telescopic pads 501 cooperate with each other to fill the gaps between the cover plates 301, forming a continuous barrier, which effectively prevents moisture, dust and other particulate matter from entering the connector and reduces wear caused by long-term use.

[0049] See also Figure 4 , Fig.11 and Fig.12 The sealing mechanism 50 further includes a moving block 506 which is slidably sleeved in the cavity at the top of the plug 403, a ratchet bar 513 is fixedly connected inside the cavity of the plug 403, a ratchet pawl 514 is fixedly connected to the side of the moving block 506, a trapezoidal groove 512 is provided on one side of the moving block 506 located in the cavity of the plug 403, a trapezoidal block 507 is slidably connected inside the cavity of the plug 403, the trapezoidal block 507 is located inside the trapezoidal groove 512, an L-rod 508 is fixedly connected to the side of the trapezoidal block 507, a cylinder 509 is fixedly connected inside the cavity of the plug 403, a piston 510 is slidably connected inside the cylinder 509, a moving rod 511 is fixedly connected to the side of the piston 510, the end of the moving rod 511 away from the piston 510 is fixedly connected to the L-rod 508, and the area between the cylinder 509 and the piston 510 is filled with mercury. The ratchet pawl 514 is made of an elastic material so that the ratchet pawl 514 is always engaged with the ratchet bar 513.

[0050] In specific operation, mercury has a large expansion coefficient. In high-temperature weather, such as summer, mercury expands due to heat. The expanded mercury pushes the piston 510 in the cylinder 509. The piston 510 simultaneously pushes the moving rod 511 to drive the L rod 508 to move. The L rod 508 simultaneously drives the trapezoidal block 507 to move during the movement. The inclined surface of the trapezoidal block 507 conflicts with the inclined surface of the trapezoidal groove 512, so that the trapezoidal block 507 pushes the moving block 506. The movable block 506 moves toward the outside of the plug 403. During the process of the movable block 506 moving outward, the movable block 506 in the plug 403 always contacts one end of the lever 503. The rotating lever 503 drives the lever 505 to rotate upward in the slide groove 504. The lever 505 pushes the telescopic pad 501 upward from the telescopic groove 502. During the process of the movable block 506 moving outward, the pawl 514 on the side of the movable block 506 always engages with the ratchet bar 513, so that the movable block 506 will not move toward the plug 403. 3, and can only move toward the outside of the plug 403; when the temperature is low, such as in winter, mercury contracts. Under the push of the external atmospheric pressure, the piston 510 synchronously pushes the moving rod 511 to drive the L rod 508 to move. During the movement of the L rod 508, the trapezoidal block 507 is synchronously driven to move. The inclined surface of the trapezoidal block 507 conflicts with the inclined surface of the trapezoidal groove 512, so that the trapezoidal block 507 pushes the moving block 506 to move toward the outside of the plug 403. During the outward movement of the moving block 506, the moving block 506 in the plug 403 always conflicts with one end of the lever 503. The rotating lever 503 drives the lever 505 to rotate upward in the slide groove 504. The lever 505 pushes the telescopic pad 501 upward from the telescopic groove 502, so that the telescopic pads 501 between the two cover plates 301 are engaged with each other. After the telescopic pads 501 are worn out after long-term use, the telescopic pads 501 can continue to fit together, so that the two cover plates 301 always maintain a sealed state.

[0051] See also Figure 6 , Fig. 9 and Fig.10 The docking mechanism 60 includes a traction rod 601 which slides horizontally through the connector 10, one end of the traction rod 601 is fixedly connected to a rack 602, and the end of the connector 10 away from the connector 20 is rotatably connected to a rotating rod 603, and a gear 604 is fixedly connected to the middle of the rotating rod 603, the gear 604 is meshed with the rack 602, and the two ends of the rotating rod 603 are rotatably connected to the two ends of a U-shaped handle 605.

[0052] Both ends of the rotating rod 603 are fixedly connected with a rotating disk 606, and the rotating disk 606 extends into the cavity of the handle 605. A plurality of mounting grooves 607 are provided on the side of the rotating disk 606. A second spring 608 is arranged inside each mounting groove 607. One end of the second spring 608 is fixedly connected to the rotating disk 606, and the other end of the second spring 608 is fixedly connected to a ball 609. A plurality of grooves 610 are provided inside the cavity of the handle 605, and a ball 609 is clamped in each groove 610.

[0053] In specific operation, when connecting the connector 10 and the connector 20, the handle 605 is rotated back and forth. When the handle 605 is rotated away from the connector 20, the groove 610 in the cavity of the handle 605 will clamp the ball 609. At this time, the handle 605 can drive the rotating rod 603 to rotate synchronously. The rotating rod 603 drives the traction rod 601 to move horizontally inside the connector 10 through the gear 604, so that the connector 20 is pulled to the connector 10 by the traction rod 601. When the handle 605 is rotated away from the connector 20, the groove 610 in the cavity of the handle 605 will clamp the ball 609. When rotating toward the connector 20, the ball 609 slides out of the groove 610 from the side of the groove 610 with a larger inclination angle. At this time, the ball 609 enters the mounting groove 607 of the rotating disk 606. Then, the handle 605 is rotated away from the connector 20, which can drive the traction rod 601 to move horizontally inside the connector 10, so that the two ends of the connector can be quickly moved together. When connecting at high places such as signal towers, the vertical connector can be pulled quickly and conveniently, which is compared to directly tightening the connector manually.

[0054] See also Figure 6 , Figure 7 and Figure 8 The traction unit also includes a correction mechanism 70, which includes a round rod 701 fixedly connected to the end of the traction rod 601 away from the rack 602, and a second accommodating groove 703 is provided at the end of the round rod 701 away from the traction rod 601. The second accommodating groove 703 is symmetrically and slidingly connected with triangular wedge blocks 702, and a third spring 704 is fixedly connected between the two wedge blocks 702. An accommodating cavity 705 is provided at one end of the connector 20 near the connector 10, and a slot 706 for matching the wedge block 702 is provided inside the accommodating cavity 705.

[0055] During specific operation, before pulling the two ends of the connector, first insert the round rod 701 at one end of the traction rod 601 into the accommodating cavity 705, and then the connector 2 20 can be rotated. The wedge block 702 outside the round rod 701 enters the slot 706 under the elastic force of the third spring 704. At this time, it can be determined that the connector 10 and the connector 2 20 are aligned. Correct alignment can reduce reflection and insertion loss at the connection and ensure effective transmission of the signal.

[0056] See also Figure 1 and Figure 6The traction unit also includes a limiting mechanism 80 for fixing the connector 10 and the connector 20. The limiting mechanism 80 includes a limiting rod 801 fixedly connected to the side of the external rectangular block 302 of the connector 10. The limiting rod 801 is fixedly connected to a clamping head 802 at one end away from the rectangular block 302. A limiting hole 803 matching the clamping head 802 is opened on the side of the external rectangular block 302 of the connector 20.

[0057] During specific operation, when the connector 10 and the connector 2 20 are fitted together through the docking mechanism 60, the clamping head 802 enters the limiting hole 803, and the connector 10 and the connector 2 20 are pre-connected and fixed by the clamping connection between the clamping head 802 and the limiting hole 803, and then the wrapping mechanism 30 is used to wrap and fix the connector.

[0058] Working principle:

[0059] When connecting the two ends of the connector, first align the connector 10 and the connector 2 20 through the correction mechanism 70, then pull the connector 2 20 to the connector 1 10 through the docking mechanism 60, and then use the limiting mechanism 80 to pre-connect and fix the connector 10 and the connector 2 20, and then use the wrapping mechanism 30 to wrap and fix the connector 10 and the connector 2 20 to protect and finally fix the connector. When the wrapping mechanism 30 wraps the connector 10 and the connector 2 20, the locking mechanism 40 tightly buckles the two cover plates 301 together while driving the sealing mechanism 50 to fill the gap between the cover plates 301.
