However, the prefabricated butterfly-shaped optical cable is often pulled and bent when in use. These actions will cause the connection between the fixing sleeve and the prefabricated butterfly-shaped optical cable body to break. After the break, the connector here can no longer be used, and even the entire section of the optical cable cannot be used. At the same time, if the staff encounters slippery materials on their hands, it is inconvenient to operate the connector of the prefabricated butterfly-shaped optical cable. Therefore, in order to solve these problems, the utility model provides a plug-in structure and a prefabricated butterfly-shaped optical cable. Utility Model Content

[0032] Example 1

[0033] Reference Figures 1 to 6 , which is the first embodiment of the utility model, provides a plug-in structure that can solve the problem of easy damage to the optical cable connection, including an accommodating component 100, an inserting component 200 arranged on the accommodating component 100, and a locking component 300 arranged on the accommodating component 100; wherein the accommodating component 100 includes a cavity component 101, and a control component 102 arranged on the cavity component 101.

[0034] Specifically, the cavity assembly 101 includes a container tube 101a, a locking groove 101b provided on the container tube 101a, a limiting ring 101c fixedly connected to the locking groove 101b, a bead 101d placed in the limiting ring 101c, a slot 101e provided on the container tube 101a, and an upper line groove 101f provided on the container tube 101a. The limiting ring 101c is provided at the upper and lower ends of the locking groove 101b, the diameter of the upper end of the inner wall of the limiting ring 101c is consistent with the locking groove 101b, and the diameter of the lower end of the inner wall of the limiting ring 101c is smaller than the diameter of the bead 101d. The limiting ring 101c is provided to help prevent the bead 101d from slipping out of the locking groove 101b.

[0035] Furthermore, the control assembly 102 includes a fixed ring 102a fixed on the outer wall of the container tube 101a, a control spring 102b fixedly connected to the fixed ring 102a, a control plate 102c fixedly connected to the control spring 102b, and a control groove 102d provided on the control plate 102c. One end of the control spring 102b is fixedly connected to the fixed ring 102a, and the other end of the control spring 102b is fixedly connected to the bottom wall of the control groove 102d. The fixed ring 102a is placed in the control groove 102d, and the fixed ring 102a is in sliding contact with the control plate 102c. When the control spring 102b is in a normal state, the inner wall of the end of the control plate 102c just fits the outer wall of the container tube 101a and presses on the bead 101d, and the inner diameter of the control plate 102c is adapted to the outer diameter of the container tube 101a.

[0036] Preferably, the plug-in component 200 includes a tube extension assembly 201 and a transfer and pressing assembly 202 disposed on the tube extension assembly 201; the cavity assembly 101 also includes a lifting surface 101g disposed on the container tube 101a. The tube extension assembly 201 includes a tube extension body 201a, a lower wire groove 201b provided on the tube extension body 201a, an extrusion surface 201c provided on the tube extension body 201a, a bead groove 201d provided on the tube extension body 201a, an exit surface 201e provided on the bead groove 201d, and an arc groove 201f provided on the tube extension body 201a. The diameter of the lower wire groove 201b is equal to that of the upper wire groove 101f. The lower wire groove 201b and the upper wire groove 101f are used to place optical cables. The extruded surface 201c is arranged at the front end of the extension tube body 201a. The extruded surface 201c facilitates the extension tube body 201a to extend into the slot 101e. The diameter of the bead groove 201d is adapted to the diameter of the card bead 101d. The provision of the exit surface 201e facilitates the card bead 101d to be separated from the bead groove 201d. There are multiple card beads 101d and card grooves, which is conducive to enhancing the fixation between the accommodating component 100 and the plug-in component 200.

[0037] It should be noted that the transfer and pressure assembly 202 includes a first fixed block 202a, a connecting column 202b fixedly connected to the first fixed block 202a, a second fixed block 202c fixedly connected to the connecting column 202b, and a rotating plate 202d rotatably connected to the connecting column 202b. The lifting surface 101g is arranged at the front end of the container tube 101a. The first fixed block 202a and the second fixed block 202c are located on the side of the arc groove 201f. One end of the rotating plate 202d is made of soft rubber material, which is conducive to fixing the optical cable through the extrusion force when the lifting surface 101g lifts the other end of the rotating plate 202d. The arc groove 201f is adapted to the rotation trajectory of the rotating plate 202d. There are multiple rotating plates 202d, which is conducive to more stable and removable fixation of the plug-in component 200 and the optical cable connector.

[0038] When in use, when the vulnerable position of the joint connection of the prefabricated butterfly-shaped introduction optical cable is changed, the accommodating component 100 and the plug-in component 200 are moved to the joint connection of the optical cable, and then the control board 102c is pushed backward to drive the control spring 102b to contract. When the control board 102c is no longer located above the locking groove 101b, the extension tube body 201a is moved into the slot 101e, and the extension tube body 201a moves forward to drive the rotating plate 202d to contact the lifting surface 101g. The lifting surface 101g continuously drives the other end of the rotating plate 202d to be lifted, and one end of the rotating plate 202d is in contact and squeezed with the optical cable joint. When the bead groove 201d and the locking groove 101 b is aligned, the extension tube body 201a contacts the bottom wall of the slot 101e, and then the control board 102c is released. At this time, the control spring 102b is reset and extended to drive the control board 102c to reset. At this time, the inner wall of the control board 102c is placed above the locking groove 101b and fits with the outer wall of the extension tube body 201a to fix the card bead 101d in the locking groove 101b and the bead groove 201d. At this time, the rotating plate 202d fixes the connector of the optical cable, the extension tube body 201a is fixed at the optical cable connector, and the container tube 101a is located on the optical cable, thereby changing the position where the prefabricated butterfly-shaped optical cable is easily damaged from the connection between the connector and the optical cable body to the optical cable body.

[0039] In summary, by fixing the accommodating component with the plug-in component, the vulnerable position of the prefabricated butterfly-shaped optical cable connector can be changed, so that the vulnerable position is changed from the connection between the connector and the optical cable body to the optical cable body. In this way, the remaining cable body on the connector can be reconnected with the broken cable body, so that the entire section of the prefabricated butterfly-shaped optical cable can continue to be used.

[0040] Example 2

[0041] Reference Figures 1 to 6 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides another locking component 300, which solves the problem that the prefabricated butterfly-shaped lead-in optical cable is not fixedly connected to the plug-in structure. The locking component 300 includes an arc pressure plate 301, a connecting rod 302 fixedly connected to the arc pressure plate 301, a plate 303 fixedly connected to the connecting rod 302, and an extrusion spring 304 sleeved on the connecting rod 302. The arc shape of the bottom wall of the arc pressure plate 301 is adapted to the optical cable. The arc pressure plate 301 is made of soft rubber material. The arc pressure plate 301 squeezes the optical cable to fix the accommodating component 100 to the optical cable.

[0042] Furthermore, the control assembly 102 also includes a top block 102e fixedly connected to the control groove 102d, and an inclined surface 102f provided on the top block 102e. The cavity assembly 101 also includes a guide groove 101h provided on the container tube 101a, and a container groove 101-i provided on the side wall of the upper line groove 101f. One end of the extrusion spring 304 is fixedly connected to the bottom wall of the guide groove 101h, and the other end of the extrusion spring 304 is fixedly connected to the abutment plate 303. The top block 102e is fixedly connected to the inner wall of the control groove 102d, and the connecting rod 302 slides up and down in the guide groove 101h and the container groove 101-i. The inclined surface 102f is provided to facilitate the smooth downward pressing of the abutment plate 303.

[0043] When in use, when the accommodating component 100 is fixed to the plug-in component 200, the control spring 102b is reset and extended to drive the control plate 102c to reset. At this time, the top block 102e follows the control plate 102c to move forward, and the inclined surface 102f begins to contact the abutment plate 303. As the control plate 102c gradually resets, the top block 102e also continuously presses the abutment plate 303 downward through the inclined surface 102f. At this time, the abutment plate 303 moves downward to drive the connecting rod 302 to move downward, and the extrusion spring 304 contracts. The connecting rod 302 moves downward, driving the arc pressure plate 301 originally located in the receiving groove 101-i to move downward and squeeze the optical cable. When the inner wall of the control board 102c is placed above the locking groove 101b and fits with the outer wall of the extension tube body 201a to fix the card bead 101d in the locking groove 101b and the bead groove 201d, at this time, the arc pressure plate 301 fixes the optical cable, so that when the optical cable is subjected to tension, the optical cable will not easily shake in the upper line groove 101f, thereby adding another layer of fixing effect to the optical cable.

[0044] In summary, the accommodating component 100 and the optical cable can be fixed by the locking mechanism, so that the optical cable will not shake easily when subjected to tension, thereby adding a layer of fixed protection for the optical cable. At the same time, because the accommodating component 100 and the plug-in component 200 are movable, the plug-in mechanism can be moved and reused on the optical cable.

[0045] Example 3

[0046] Reference Figure 7 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a prefabricated butterfly-shaped lead-in optical cable, which solves the problem that when connecting the optical cable connection, it is inconvenient to fix the connection when slipping. It includes the plug-in structure in the above embodiment, including a main body component 400; the main body component 400 includes a prefabricated butterfly-shaped lead-in optical cable body 401, a handle 402, and a connector fixing sleeve 403; the handle 402 is fixedly connected to the control component 102.

[0047] Furthermore, the pull handle 402 is fixedly connected to the outer wall of the control board 102c, and the prefabricated butterfly-shaped lead-in optical cable body 401 is placed in the upper wire groove 101f and the lower wire groove 201b, so that the control board 102c can be pulled by the pull handle 402.

[0048] During use, when the staff's hand slips or the control panel 102c contacts a relatively slippery substance, the staff is likely to slip when pushing the control panel 102c. Therefore, in this case, the staff can easily push the control panel 102c through the handle 402 to fix or separate and move the accommodating component 100 and the plug-in component 200.
