[0009] Preferably, the two vertical frames are movably connected with the two perforated sheets respectively, the second spring is located between the rectangular sheet and the perforated sheet, the pin is inserted into the slot, and the slot is movably connected with the annular slot at the corresponding position.

[0010] Preferably, the front ends of the two protective covers are closed, two splicing grooves are provided on the two protective covers, and a semicircular groove is provided on the front ends of the two protective covers. A pair of arc-shaped fixing seats are fixedly connected to the upper and lower ends of the outer wall of the socket end, and a pair of parallel track rods are fixedly connected between each pair of arc-shaped fixing seats. Two spring threes are movably connected to each track rod, and two arc-shaped sliding seats are movably connected to each pair of track rods. Spring three is located between the arc-shaped sliding seat and the arc-shaped fixing seat, wherein round holes are provided on the two arc-shaped fixing seats located at the front section, and a middle groove is provided in the middle part of an arc-shaped sliding seat located at the upper end close to the top rod.

[0011] Preferably, each arc-shaped fixing seat with a circular hole is fixedly connected to a pair of cross frames, each pair of cross frame ends are rotatably connected to a pair of rotating plates, and each pair of rotating plates are rotatably connected to a top plate, wherein the top plate and the circular hole are aligned.

[0012] Preferably, two rotating racks are rotatably mounted on each arc-shaped sliding seat, and the other ends of the rotating racks are rotatably mounted on the middle part of the splicing groove.

[0013] Preferably, the upper surfaces of the two arc-shaped fixing seats at the upper end are fixedly connected with an arc-shaped cover plate, and the lower surfaces of the two arc-shaped fixing seats at the lower end are fixedly connected with the same arc-shaped cover plate, wherein the structure composed of the arc-shaped cover plate and the two arc-shaped fixing seats is stuck in the groove body composed of two splicing grooves.

[0014] Preferably, rope rings are provided at the bottom of the protective sleeve and the plug end, a connecting rope is tied between the two rope rings, and a blocking piece is also fixed on the protective sleeve.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, during the movement of the arc-shaped sliding seat, the two protective covers are separated by the deflection of the rotating frame, thereby achieving the effect of automatically and quickly separating the protective covers during the plug-in process of the plug end and the socket end. After the protective covers are unfolded, the thumb-up pull piece can be used again to release the limit on the push rod, and the reverse force of the push plate on the push rod can be used to make the push rod retract into the long groove. When the plug end and the socket end are merged, the two hooks just clamp the arc-shaped fixed seat, so that the plug end and the socket end remain connected, thereby achieving the effect of self-locking during the connection process.

[0017] In the present invention, when it is necessary to disassemble the plug end and the socket end, it is only necessary to pull the hook to disengage the hook from the arc-shaped fixing seat to separate the plug end and the socket end. After separation, it is only necessary to pinch the two protective covers, and the two protective covers approaching each other will push the arc-shaped sliding seat close to the arc-shaped fixing seat through the rotating frame. When the two protective covers are combined into a complete cover body, the cross frame will be squeezed and bent and pass through the middle groove, and then the arc-shaped sliding seat will be clamped by the restored cross frame to achieve the effect of quickly closing the socket end. The operator only needs to pinch the two protective covers to complete the closed protection of the socket end. The internal structure completes the linkage completely automatically, and the operation is simple and efficient.

[0018] In the present invention, after the plug end is pulled out, the paddle is lifted up, and the operator can hold the protective cover and put it on the plug of the plug end. During the sleeve connection process, the blocking piece is retracted into the long groove against the ejector rod. When the blocking piece contacts the strip seat, the protective cover and the plug end are completely merged. At this time, the paddle can be released, and the ejector rod is re-fixed by using the paddle to snap into the annular groove. The operator only needs to control the paddle with the thumb and then put on the protective cover to complete the protection of the plug end and reset the ejector rod. The operation is simple and quick.

[0019] In the present invention, the socket end and the plug end are respectively sealed and protected by the protective cover and the protective sleeve, which can effectively prevent dust, impurities, etc. from entering the connector interface, thereby achieving the effect of signal crosstalk prevention. Dust, impurities, etc. entering the connector interface may cause problems such as poor contact, short circuit, signal interference, etc., and then cause crosstalk in signal transmission. Keeping the inside of the connector clean and clean ensures the stability and reliability of signal transmission, and can also improve the sealing of the connector, prevent moisture and liquid from entering the connector interface, and further enhance the protection effect against signal interference.

[0020] In the present invention, since the hole formed by the semicircular groove is small, the socket end can be easily opened only when the push rod on the plug end is inserted. Otherwise, the socket end is not easy to open. Without the plug end, it is difficult to open the socket end normally without destroying the protective mechanism. Compared with the common method of directly putting on the protective cover, it not only avoids the problem of easy loss of the protective cover, but also effectively improves information security, and prevents the socket end from being easily used by unrelated personnel in the absence of the plug end.

[0021] In the present invention, the small parts of the protection component are shielded by the arc-shaped cover plate, which improves the aesthetics and also greatly avoids the small parts in the protection component from being accidentally touched and affecting normal use, thereby increasing the service life.

[0036] The front ends of the two protective covers 3 are both closed, and two splicing grooves 31 are provided on the two protective covers 3. The front ends of the two protective covers 3 are also provided with semicircular grooves 28. The upper and lower ends of the outer wall of the socket end 2 are fixedly connected with a pair of arc-shaped fixed seats 32, and a pair of parallel track rods 36 are fixedly connected between each pair of arc-shaped fixed seats 32. Two springs 34 are movably sleeved on each track rod 36, and two arc-shaped sliding seats 39 are movably sleeved on each pair of track rods 36. The springs 34 are located between the arc-shaped sliding seats 39 and the arc-shaped fixed seats 32. Among them, the two arc-shaped fixed seats 32 located in the front section are provided with round holes 33, and the middle part of the arc-shaped sliding seat 39 located at the upper end near the top rod 7 is provided with a middle groove 4 0, each arc-shaped fixed seat 32 with a circular hole 33 is fixedly connected to a pair of cross frames 38, each pair of cross frames 38 ends are rotatably connected to a pair of rotating plates 37, each pair of rotating plates 37 are rotatably connected to a top plate 35, wherein the top plate 35 is aligned with the circular hole 33, each arc-shaped sliding seat 39 is rotatably mounted with two rotating frames 30, the other end of the rotating frame 30 is rotatably mounted on the middle part of the splicing groove 31, the upper surfaces of the two arc-shaped fixed seats 32 at the upper end are fixedly connected to the arc-shaped cover plates 29, and the lower surfaces of the two arc-shaped fixed seats 32 at the lower end are fixedly connected to the same arc-shaped cover plates 29, wherein the structure composed of the arc-shaped cover plates 29 and the two arc-shaped fixed seats 32 is stuck in the groove body composed of the two splicing grooves 31;

[0037] Rope rings 8 are provided at the bottom of the protective sleeve 4 and the plug end 1 , a connecting rope is tied between the two rope rings 8 , and a blocking piece 9 is also fixed on the protective sleeve 4 .

[0038] Working principle: When plugging the plug end 1 and the socket end 2, the operator holds the plug end 1 and the socket end 2 with both hands respectively, holds the thumb of the plug end 1 against the hole of the paddle 10, and then lifts the paddle 10 upward with the thumb. During the upward movement of the paddle 10, the plug pin 15 moves upward and disengages from the annular groove 16. At this time, the ejector rod 7 loses the limit of the plug pin 15 and can be ejected until the slider 27 is against the farthest end of the long groove 25. At this time, the ejector rod 7 can no longer move, and the thumb can be removed from the paddle 10. The spring 21 is used to reset the paddle 10, so that the plug pin 15 is clamped on the ejector pin 7 again. At this time, the plug end 1 and the socket end 2 are operated to approach each other. The ejector 17 on the ejector pin 7 first passes through the semicircular groove 28 and the circular hole 33, and then contacts the ejector plate 35. As the plug end 1 and the socket end 2 continue to approach each other, the ejector 17 squeezes the ejector plate 35, so that the squeezed and displaced ejector plate 35 drives the ends of the two cross frames 38 to approach each other through the deflectable rotating plate 37. The two ends of the arc sliding seat 39 can slide towards the middle part of the arc cover plate 29 under the pulling force of the spring three 34. The cross frame 38 close to each other at both ends can pass through the middle groove 40 without affecting the movement of the arc sliding seat 39. During the movement of the arc sliding seat 39, the deflection of the rotating frame 30 will separate the two protective covers 3, so that the protective cover 3 can be automatically and quickly separated during the plug-in connection between the plug end 1 and the socket end 2. After the protective cover 3 is unfolded, the upper thumb lifting piece 10 can be used again to release the limit on the ejector rod 7, and the reverse force of the ejector plate 35 on the ejector rod 7 can be used to make the ejector rod 7 retract into the long groove 25. When the plug end 1 and the socket end 2 are combined, the two hooks 22 just clamp the arc fixing seat 32, so that the plug end 1 and the socket end 2 remain connected, so as to achieve the effect of self-locking during the connection process.

[0039] When the plug end 1 and the socket end 2 need to be disassembled, the plug end 1 and the socket end 2 can be separated by only pulling the hook 22 to disengage the arc-shaped fixing seat 32. After separation, the two protective covers 3 can be pinched together. The two protective covers 3 approaching each other will push the arc-shaped sliding seat 39 to approach the arc-shaped fixing seat 32 through the rotating frame 30. When the two protective covers 3 are combined into a complete cover body, the cross frame 38 will be squeezed and bent and pass through the middle groove 40. Then, the arc-shaped sliding seat 39 is clamped by the restored cross frame 38, so as to achieve the effect of quickly closing the socket end 2. The operator only needs to pinch the two protective covers 3 together to complete the closed protection of the socket end 2. The internal structure is fully automatically linked, and the operation is simple and efficient.

[0040] After the plug end 1 is pulled out, the paddle 10 is lifted up, and the operator can hold the protective cover 4 and put it on the plug of the plug end 1. During the sleeve connection process, the baffle 9 is pressed against the ejector rod 7 and retracted into the long groove 25. When the baffle 9 contacts the strip seat 5, the protective cover 4 and the plug end 1 are completely merged. At this time, the paddle 10 can be released, and the ejector rod 7 is re-fixed by using the paddle 10 to snap into the annular groove 16. The operator only needs to control the paddle 10 with the thumb and then put on the protective cover 4 to complete the protection of the plug end 1 and the reset of the ejector rod 7. The operation is simple and quick.

[0041] The protective cover 3 and the protective sleeve 4 are used to respectively seal and protect the socket end 2 and the plug end 1, which can effectively prevent dust, impurities, etc. from entering the connector interface, thereby achieving the effect of signal crosstalk prevention. Dust, impurities, etc. entering the connector interface may cause problems such as poor contact, short circuit, signal interference, and further cause signal transmission crosstalk. Keeping the inside of the connector clean and clean ensures the stability and reliability of signal transmission. It can also improve the sealing of the connector, prevent moisture and liquid from entering the connector interface, and further enhance the protection effect against signal interference;

[0042] Since the hole formed by the semicircular groove 28 is small, the socket end 2 can be easily opened only when the push rod 7 on the plug end 1 is inserted, otherwise the socket end 2 is not easy to open. Without the plug end 1, it is difficult to open the socket end 2 normally without destroying the protection mechanism. Compared with the common method of directly putting on the protective cover, it not only avoids the problem of easy loss of the protective cover, but also effectively improves information security, and prevents the socket end 2 from being easily used by unrelated personnel without the plug end 1;

[0043] The small parts of the protection component are all covered by the arc-shaped cover plate 29, which improves the aesthetics and also greatly avoids the small parts in the protection component from being accidentally touched and affecting normal use, thereby increasing the service life.

[0044] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
