However, in actual application scenarios, the existing communication device connector has the problem of easy cable dropping. Vibration may occur during device use, and long-term vibration will cause the connection part of the connector and the cable connection port to be continuously subjected to periodic forces, resulting in gradual relaxation of the connection part and a decrease in connection tightness. In addition, during daily operation or accidental situations, the cable may be unintentionally pulled by external forces, such as accidental pulling of the cable by the staff during device maintenance, or the cable being squeezed and pulled due to space limitations during wiring. These vibrations and external forces will gradually damage the original tight connection between the connector and the cable, causing the cable to drop, thereby interrupting communication signal transmission or power supply, seriously affecting the normal operation of the communication device, and even causing communication failure.

DETAILED DESCRIPTION

[0017] In order to make the technical personnel in the field better understand the technical solutions of the present application, the present application will be further described in detail below with reference to the drawings.

[0018] Example one Please refer to Figures 1-4 and Figure 6 The communication equipment anti-disconnection connector provided by the embodiment of the present application comprises a body 1, two closing members 2, two clamping members and a transmission assembly. The body 1 is provided with a plug slot 101, and the plug slot 101 is internally provided with a mating head 102. The body 1 is provided with two extension arms, and the two extension arms are respectively located on both sides of the plug slot 101. The two closing members 2 are respectively rotationally connected to the body 1, and have a closing position for closing the plug slot 101 in the process of rotation. The two clamping members are respectively and correspondingly slidably connected to the two extension arms of the body 1. When the two clamping members are closed, the cable 501 is clamped and fixed. The transmission assembly drives the clamping members to reciprocate. Specifically, in the process that the plug 5 of the communication equipment is inserted into the plug slot 101, the plug 5 pushes the two closing members 2 away from the closing position, so as to be in communication connection and / or conductive connection with the mating head 102. In the process that the two closing members 2 are opened, the two clamping members are driven by the transmission assembly to be closed, so as to clamp the cable 501 connected to the plug 5.

[0019] The clamping member comprises a sliding rod 3 and an arc-shaped clamping block 301 which are fixedly connected to each other. The corresponding extension arm is fixedly connected with a fixed tube. The sliding rod 3 is slidably inserted into the fixed tube. When the plug 5 has not been inserted, the two sets of clamping members are in a state of being away from each other, and the distance between the two sets of clamping members only supports the plug 5 to pass through smoothly, so that the cable 501 of the plug 5 can be clamped smoothly when the two clamping members are driven by the transmission assembly to be closed, and the problem of the cable 501 of the plug 5 slipping off is avoided. By arranging the clamping member, after the plug 5 is inserted into the body 1, the clamping member fixes the cable 501, which is beneficial to ensuring the neatness of the cable 501 when a plurality of bodies 1 are connected, and is helpful to further enhancing the stability of the plug 5 in the body 1, avoiding the loose of the plug 5 in the plug slot due to the random shaking of the cable 501. It should be noted that a small section of the cable 501 needs to be reserved in advance before the end of the plug 5 is in contact with the mating head 102 and the clamping member completely clamps the cable 501. Figure 5The effect shown avoids the complete straightening of the part of the cable 501 between the clamping member and the plug-in connector 5, which is beneficial for preventing excessive tension caused by clamping the cable too tightly, affecting the stability and connectivity between the cable and the plug-in connector; and is beneficial for the cable 501 to adapt to changes, reserving the length of the cable 501 to adapt to the line expansion caused by the change of environmental temperature and the demand during the fine adjustment of the equipment.

[0020] Specifically, the transmission assembly includes an oil path 4, a first piston 401, a second piston 402, and a first elastic member 403. The oil path 4 is formed in the device body 1, one end of which is communicated to the first cavity of the plug-in slot 101, and the other end is communicated to the fixed tube. The first piston 401 is fixedly connected to the sliding rod 3, and the second piston 402 is slidingly connected to one end of the oil path. The second piston 402 is fixedly connected with a push block 404 through a connecting rod. The oil path is filled with pressure oil. When the plug-in connector 5 pushes the closure 2 to open, the rotating closure 2 pushes the push block 404 to move into the oil path 4. The push block 404 controls the second piston 402 through the connecting rod, and drives it to move along the oil path 4. The oil path 4 is in the shape of U. During the movement of the second piston 402, the pressure oil is pushed to flow along the oil path 4. The pressure oil then pushes the clamping member to displace, so that the clamping member completes the clamping and fixing of the cable 501.

[0021] The process of restoring the deformation of the first elastic member 403 drives the second piston 402 to slide in the direction of the first cavity to make the push block 404 press against the closure 2 in the fully open state, thereby strengthening the extrusion and clamping of the closure 2 on the plug-in connector 5. The first elastic member 403 can be a tensile spring, such as Figure 5 As shown, the first elastic member 403 is sleeved on the connecting rod, one end of which is fixed with the oil path 4, and the other end is fixed with the second piston 402. When the closure 2 pushes the push block 404, the first elastic member 403 is stretched with the movement of the second piston 402. When the plug-in connector 5 leaves the plug-in slot 101, the closure 2 and the push block 404 lose the extrusion force, and the first elastic member 403 is elastically released. The first elastic member 403 pulls back the second piston 402, so that a suction force is generated in the oil path 4. The pressure oil and the first piston 401 are affected by the suction force and move with the movement of the second piston 402. The moving first piston 401 moves into the oil path 4 and pulls the clamping member to move, so that the clamping member unlocks the cable 501, and the plug-in connector 5 can be completely separated from the device body 1.

[0022] Furthermore, the closing member 2 includes a baffle 201, a dustproof plate 203 and a magnetic rod 205. The baffle 201 is rotatably installed in the first cavity through a rotating shaft. A second elastic member 204 is arranged between the baffle 201 and the dustproof plate 203. The second elastic member 204 is a compression spring. When the plug connector 5 pushes the dustproof plate 203 to open the closing member 2, the second elastic member 204 is compressed. The second elastic member 204 always pushes the dustproof plate 203 to push the plug connector 5 due to its elasticity. When the equipment vibrates, the second elastic member 204 helps to buffer and shock the plug connector 5, so that the plug connector 5 is always plugged into the device body 1. When the plug connector 5 is away from the dustproof plate 203, the second elastic member 204 is elastically released to push the dustproof plate 203 to reset. The two sets of dustproof plates 203 are docked laterally and the opening of the plug slot 101 is closed to avoid a large amount of dust accumulating in the plug slot 101 due to electrostatic adsorption.

[0023] A second cavity 202 is provided in the baffle 201, and a magnetic rod 205 is slidably inserted in the second cavity 202. When the push block 404 pushes the closing piece 2 to rotate, the push block 404 may fail to push the closing piece 2 to rotate completely 90 degrees. By setting two sets of opposing magnetic rods 205, during the rotation of the closing piece 2, the two sets of magnetic rods 205 attract each other, partially slide out from the second cavity 202 until the two contact each other, and then the attraction between the two can promote the rotation of the closing piece 2. The magnetic rod 205 is composed of two magnets, and the magnet close to the push block 404 is more magnetic than the magnet close to the dustproof plate 203 to ensure that after the two sets of magnetic rods 205 contact at the side ends, the two sets of closing pieces 2 can still rotate to a state perpendicular to each other.

[0024] An airbag 206 is provided in the second cavity 202, and a telescopic rod 207 is fixedly installed on the second cavity 202, and the fixed end of the telescopic rod 207 is communicated with the airbag 206, the telescopic rod 207 is communicated with the gas in the airbag 206, and the telescopic end of the telescopic rod 207 is fixedly connected to the dustproof plate 203. When the telescopic end of the telescopic rod 207 is extended, part of the gas in the airbag 206 will flow to the telescopic rod 207. The reduction in the volume of the airbag 206 is conducive to the sliding recovery of the magnetic rod 205 into the second cavity 202. When the telescopic end of the telescopic rod 207 is contracted, the gas in the contraction space of the telescopic rod 207 enters the airbag 206, the airbag 206 expands, and the airbag 206 pushes the magnetic rod 205 to slide outward, so as to ensure that the distance between the two groups of magnetic rods 205 is always within the effective magnetic attraction range, thereby avoiding the problem that the two groups of magnetic rods cannot attract each other due to being too far apart.

[0025] So set up, such as Figure 3 and Figure 5As shown, the two groups of dustproof plates 203 are kept in the same horizontal plane to close the opening of the plug-in slot 101 to play a dustproof role. When the plug-in head 5 pushes the two closures 2 away from the closing station to communicate and / or conductively connect with the counter plug-in head 102, the plug-in head 5 pushes the dustproof plates 203 to extrude the second elastic member 204, and pushes the closure 2 to rotate. In this process, the dustproof plates 203 push the telescopic end of the telescopic rod 207 to retract, the gas in the retracted space of the telescopic rod 207 enters the air bag 206, the air bag 206 expands, and the air bag 206 pushes the magnetic rod 205 to slide outward to facilitate the reverse rotation of the closure 2 to close, and the two groups of magnetic rods 205 can attract each other.

[0026] When it is necessary to separate the plug-in end from the body 1, the cable 501 close to the plug-in end part is pulled, and when the end of the plug-in end passes and moves away from the dustproof plate 203, the closure 2 loses the pushing force of the plug-in end, the first elastic member 403 is elastically released, the push block 404 pushes the closure 2 to rotate reversely, and the two groups of magnetic rods 205 gradually approach and attract each other. At the same time, the second elastic member 204 is also elastically released, the telescopic end of the telescopic rod 207 is extended, part of the gas in the air bag 206 flows to the telescopic rod 207, the volume of the air bag 206 decreases, and the sliding recovery of the magnetic rod 205 into the second cavity 202 provides a spare space. The two groups of magnetic rods 205 abut against each other during the rotation of the baffle 201, and push each other to move into the second cavity 202 on the opposite side, so as to facilitate the vertical movement of the two groups of baffles 201, and the side-to-side abutment of the two groups of dustproof plates 203 to close the opening of the plug-in slot 101.

[0027] Further, a plurality of positioning members 103 are fixedly installed on the body 1, and a plurality of positioning grooves are formed on the side of the body 1 away from the positioning members 103. The positioning members 103 and the positioning grooves are one-to-one corresponding. When assembling a plurality of bodies 1, the positioning member 103 of one group of bodies 1 can be installed into the corresponding positioning groove of another group of bodies 1, so as to realize the stable connection of the plurality of bodies 1 in the vertical direction.

[0028] The body 1 is provided with a clamping groove 104 on both sides, and the clamping grooves 104 of the two groups of bodies 1 are connected by a connecting member 1041. When assembling a plurality of bodies 1, the two groups of adjacent bodies 1 kept in the same horizontal plane can be connected by the connecting member 1041.

[0029] The end of the baffle 201 is fixedly installed with an indicating member 208, and the indicating member 208 is located outside the body 1. The indicating end of the indicating member 208 and the baffle 201 are at the same angle, so that the user can check the rotation angle of the closure 2 through the indicating member 208. In addition, if the transmission assembly is jammed or has other faults, the user can manually control the rotation of the closure 2 through the indicating member 208.

[0030] The body 1 is provided with an indicator lamp 105, and the indicator lamp 105 is located on the side away from the plug-in slot 101, and the indicator lamp 105 is three different color bulbs, when the connector 102 is connected with the plug-in head 5, the yellow indicator lamp 105 is lit, when the output line terminal of the body 1 is connected with the communication equipment, the green indicator lamp 105 is lit, when the connector 102 is connected with the plug-in head 5, and the terminal of the indicator lamp 105 is connected with the communication equipment, if the communication connection is not completed, the red indicator lamp 105 is lit, through the indicator lamp 105, the specific connection failure problem point of the connector can be quickly judged, and the maintenance efficiency of the maintenance personnel is improved.

[0031] In the above technical scheme, the communication equipment connector provided by the application is used for connecting the communication equipment, the plug-in head 5 pushes the two closing pieces 2 from the closing position to be connected with the connector 102 for communication connection and / or conductive connection, the closing piece 2 rotates, the closing piece 2 pushes the push block 404 to move along the oil path 4, so that the second piston 402 pushes the pressure oil to flow along the oil path 4, and then the pressure oil pushes the clamping piece to displace, the two clamping pieces are closed to clamp the cable 501 connected with the plug-in head 5, and meanwhile, the second elastic piece 204 always pushes the dustproof plate 203 to push the plug-in head 5 due to the elasticity, and the second elastic piece 204 helps to buffer and shock absorb the plug-in head 5 when the equipment vibrates.

[0032] Embodiment two Please refer to Figure 5 Based on the same concept as the above embodiment one, the embodiment further provides a rectangular plug-in slot 101, so that the plug-in end of the connector can be adapted to the plug-in heads of different types of cables.

[0033] In addition, the first elastic piece 403 of the transmission assembly can also be a compression spring, a limiting ring is arranged at the corner of the oil path 4 close to the first cavity, one end of the first spring piece is fixedly connected with the limiting ring, and the other end of the first spring piece is fixedly connected with the second piston 402, when the closing piece 2 pushes the push block 404, the second piston 402 extrudes the compression spring, conversely, when the plug-in head 5 is away from the closing piece 2, the first elastic piece 403 is elastically released, the first elastic piece 403 pushes the second piston 402 to the first cavity, and then pushes the push block 404 to reset.

[0034] The above only describes some exemplary embodiments of the application by way of illustration, and it is self-evident that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the application.
