[0043] A protective cylinder 2, wherein the protective cylinder 2 is fixedly connected to the optical cable plug 1, and the protective cylinder 2 is also sleeved on the optical cable connector 3 and is detachably connected to the optical cable connector 3;

[0045] and a protection control mechanism, which is respectively connected to the optical cable plug 1, the protection cylinder 2 and the optical cable connector 3, and is respectively connected to the guide sleeve 5 and the optical cable body 9, wherein the protection control mechanism includes a disengagement control component, a drive component and a speed detection component;

[0046] The pushing-apart control assembly is respectively connected to the protective cylinder 2 and the optical cable connector 3, the driving assembly is respectively connected to the optical cable plug 1, the guide sleeve 5 and the optical cable body 9, and is connected to the pushing-apart control assembly, and the speed detection assembly is respectively connected to the guide sleeve 5 and the driving assembly.

[0047] It also includes: a limit slot 12, the limit slot 12 is fixedly mounted on the connecting column 11;

[0048] And a V-shaped plug-in strip 25, which is located on the inner wall of the optical cable connector 3, and the V-shaped plug-in strip 25 is also inserted into the limiting card slot 12 and is detachably connected to the limiting card slot 12.

[0049] During the use of the optical cable connector, first, the optical cable plug 1 and the optical cable connector 3 can be plugged together to complete the signal transmission. At this time, under the interference fit of the limit card groove 12 and the V-shaped plug strip 25, the stability of the plugging between the optical cable plug 1 and the optical cable connector 3 can be guaranteed, and the two can be guided during the plugging process to ensure that the two are quickly and firmly connected together. Then, through the provided protection control mechanism, when the optical cable body 9 is suddenly hit during use, the optical cable body 9 will be quickly moved a distance in the guide sleeve 5. At this time, the optical cable body 9 will not generate a pulling force on the optical cable plug 1.

At the same time, in the process of gradually increasing external pressure, the optical cable plug 1 and the optical cable connector 3 can also be slowly separated, thereby achieving the purpose of protecting the connector and providing convenience for the staff.

[0050] In one embodiment of the present invention, see Figure 1-Figure 6 , the opening control component includes:

[0051] Open the control box 13, wherein the control box 13 is fixedly mounted on the protection cylinder 2 and communicated with the protection cylinder 2;

[0052] An incomplete gear 15, wherein the incomplete gear 15 is rotatably mounted in the prying control box 13 via an adjustable damping shaft 16, and the incomplete gear 15 is also connected to a driving assembly, wherein the incomplete gear 15 is provided with a free separation portion 17 and a meshing resistance portion 18;

[0053] And a rack 26, the rack 26 is located on the outer side wall of the optical cable connector 3, and the rack 26 is also detachably connected to the free separation portion 17 and the meshing resistance portion 18 respectively.

[0054] The drive assembly comprises:

[0055] A connecting sleeve 10, wherein the connecting sleeve 10 is connected to the optical cable plug 1 and the control box 13 respectively;

[0056] A driving rope 19, one end of which is fixedly connected to the incomplete gear 15, and the other end of which passes through the connecting sleeve 10 and is slidably connected to the connecting sleeve 10, and the other end of which is also connected to the speed detection component;

[0057] And a control unit, wherein the control unit is connected to the guide sleeve 5 and the connecting sleeve 10 respectively.

[0058] The control unit comprises:

[0059] A buffer control box 6, wherein the buffer control box 6 is fixedly connected to the guide sleeve 5 and the connecting sleeve 10 respectively, and the buffer control box 6 is also connected to the guide sleeve 5 through a communication notch 21;

[0060] A sliding sleeve 22, wherein the sliding sleeve 22 is fixedly installed in the buffer control box 6 and sleeved on the driving rope 19;

[0061] And an optical cable buffer portion 20 , wherein the optical cable buffer portion 20 is located on the optical cable body 9 , and the optical cable buffer portion 20 also passes through the communication slot 21 and is located in the buffer control box 6 .

[0062] The speed detection component comprises:

[0063] A controller 7, wherein the controller 7 is fixedly mounted on the buffer control box 6;

[0064] A push sliding cavity 8, wherein the push sliding cavity 8 is fixedly connected to the guide sleeve 5, and the push sliding cavity 8 is also respectively connected to the controller 7 and the optical cable body 9;

[0065] A telescopic sliding member 24, which is clamped in the communication slot 21 and connected to the push sliding cavity 8, and the telescopic sliding member 24 is also slidably connected to the communication slot 21;

[0066] And an arc-shaped linkage plate 23 , wherein the arc-shaped linkage plate 23 is fixedly mounted on the telescopic sliding member 24 , and the arc-shaped linkage plate 23 is also detachably connected to the optical cable body 9 .

[0067] When the optical cable body 9 is hit, the optical cable body 9 moves in the guide sleeve 5 and pulls the optical cable buffer 20 out of the buffer control box 6 (after the external force treatment is completed, the optical cable buffer 20 can be pulled into the buffer control box 6 again by human pulling). At this time, the optical cable body 9 does not exert a pulling force on the optical cable plug 1, and in this process, the pushing sliding cavity 8 detects the moving speed of the optical cable body 9, wherein a speed detection sensor is provided in the pushing sliding cavity 8, which can detect the moving speed of the optical cable body 9. When the moving speed of the optical cable body 9 is greater than the preset When the value is set, the telescopic sliding member 24 will start working, wherein the telescopic sliding member 24 can be in the form of an electric telescopic rod, or in the form of an electromagnet-controlled telescopic rod, as long as the arc-shaped linkage plate 23 can be pushed and pulled to move up and down, no further elaboration will be given here. Under the control of the telescopic sliding member 24, the arc-shaped linkage plate 23 will contact the moving optical cable body 9, and under the driving action of the optical cable body 9, the telescopic sliding member 24 can slide smoothly in the pushing sliding cavity 8 and the connecting notch 21, and pull the driving rope 19 to move, thereby driving the incomplete gear 15 to rotate clockwise by a certain angle (such as Figure 4As shown), after the incomplete gear 15 rotates, the free separation portion 17 can be directly opposite to the rack 26. At this time, the optical cable buffer portion 20 completely enters the guide sleeve 5, and the optical cable body 9 also just produces a pulling force on the optical cable plug 1, so that the optical cable plug 1 and the optical cable connector 3 can be quickly separated. Among them, one side of the incomplete gear 15 is rotatably connected to the open control box 13 through an adjustable damping shaft 16, and the side provided with a driving pull rope 19 is not connected to the open control box 13, so as to avoid interference with the driving pull rope 19 when the incomplete gear 15 rotates. In addition, after the optical cable plug 1 and the optical cable connector 3 are connected, the incomplete gear 15 is rotated by manpower, so that the first tooth on the meshing resistance portion 18 can be meshed with the rack 26, and the resistance size of the rotation of the incomplete gear 15 can be set manually through the adjustable damping shaft 16. When the driving pull rope 19 pulls the incomplete gear 15 to rotate clockwise, the meshing resistance portion 1 The first tooth on 8 will push the rack 26 and the optical cable connector 3 to move a short distance in the direction of the optical cable plug 1 (there is a certain gap between the optical cable plug 1 and the optical cable connector 3), so that the free separation part 17 can be smoothly rotated to a position opposite to the rack 26. No further details will be given here. When the moving speed of the optical cable body 9 is less than the preset value, when the optical cable buffer part 20 completely enters the guide sleeve 5 and exerts a pulling force on the optical cable plug 1, under the meshing action of the meshing resistance part 18 and the rack 26, the optical cable plug 1 and the optical cable connector 3 will be limited, thereby ensuring the stability of the connection between the optical cable plug 1 and the optical cable connector 3. When the external force continues to increase and is greater than the resistance of the adjustable damping shaft 16, the incomplete gear 15 will rotate counterclockwise. At this time, the meshing resistance part 18 continues to mesh with the rack 26, so that the optical cable plug 1 and the optical cable connector 3 are separated smoothly to avoid damage to the connector.

[0068] In one embodiment of the present invention, it further comprises: a position detector 4 , wherein the number of the position detectors 4 is multiple, and the multiple position detectors 4 are respectively located on the optical cable plug 1 and the optical cable connector 3 .

[0069] During the installation and use of the optical cable plug 1 and the optical cable connector 3, the positions of the optical cable plug 1 and the optical cable connector 3 can be detected by means of a plurality of position detectors 4, wherein the position detector 4 can be in the form of a photoelectric sensor to detect the distance and angle between the optical cable plug 1 and the optical cable connector 3, so that during use, the stability of the connection between the optical cable plug 1 and the optical cable connector 3 can be monitored in real time, and after the optical cable plug 1 and the optical cable connector 3 are separated from each other, the staff can be reminded in time, so as to facilitate the staff to check and repair the optical cable plug 1 and the optical cable connector 3.
