Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber connection boxes, in particular to an optical fiber connection box with a branching structure. Background Art

[0002] A fiber optic connection box is a device used to connect and distribute optical fibers, also known as a fiber optic splice box or a fiber optic access box. It is commonly used in optical communication networks to protect optical fiber connections, distribute optical signals, and manage optical cables. Fiber optic connection boxes can be divided into indoor and outdoor types according to different installation locations and uses. In optical communication networks, fiber optic connection boxes are very important equipment used to ensure the transmission quality of optical signals and the stability of the network. During the use of existing fiber optic connection boxes, when multiple optical fiber pigtails share a collection point, signal attenuation and interference may occur, especially in high-speed data transmission or long-distance transmission, which may affect network performance and stability; so we propose a fiber optic connection box with a branching structure to solve the above problems. Utility Model Content

[0003] In order to overcome the problem that signal attenuation and interference may occur when multiple optical fiber pigtails share a collection point during the use of existing optical fiber connection boxes, especially during high-speed data transmission or long-distance transmission, which may affect network performance and stability.

[0004] The technical solution of the utility model is: an optical fiber connection box with a branching structure, comprising a box body, a supporting assembly, a placement assembly and a clamping assembly; a supporting assembly for supporting the placement assembly and the clamping assembly is installed at the inner bottom of the box body, a plurality of groups of placement assemblies for placing optical fibers are horizontally arranged in the middle of the supporting assembly, and two groups of clamping assemblies for clamping optical fibers are horizontally installed at the upper end of the supporting assembly.

[0005] Preferably, after placement is completed, the snap-in column drives the square telescopic sleeve to be positioned and connected with the U-shaped frame through the snap-in hole, and then the optical fiber is passed through the circular hole and the middle of the first arc-shaped telescopic column. Then, through the adjustment of the first pin and the second pin, the square telescopic column and the strip telescopic column move laterally along the square telescopic sleeve and the strip telescopic sleeve. During this process, the first arc-shaped telescopic column shrinks along the first arc-shaped telescopic sleeve 405 and the second arc-shaped telescopic sleeve until they fit the optical fiber to fix the position of the optical fiber. Then, the first pin and the second pin pass through the hole to fix the position of the square telescopic column and the strip telescopic column. In this way, one optical signal can be divided into multiple ones. After the optical fiber is placed, the flip cover is closed, and the heat flow can flow out through the heat dissipation hole to avoid heat flow accumulation inside the combination and affect the operation of the optical fiber.

[0006] Preferably, four groups of circular holes for the optical fiber to pass through are symmetrically opened on both sides of the box body, and a strip-shaped slot for the optical fiber to pass through is opened below the circular holes of the box body, a rotating column is installed on one side of the upper end of the box body, and a flip cover is provided on the top of the box body, which is rotatably connected to the box body through the rotating column, and a handle is installed on the upper end of the flip cover away from the box body, and a plurality of heat dissipation holes for the heat flow to flow out are opened in an array below the flip cover where the handle is installed, and the flip cover is rotated and opened with the rotating column and the box body by pulling the handle. After the optical fiber is placed in, the flip cover is closed and the heat flow can flow out through the heat dissipation holes, thereby avoiding the accumulation of heat flow inside the assembly and affecting the operation of the optical fiber.

[0007] Preferably, the support assembly includes a base plate and a U-shaped frame, two groups of snap-in grooves for placing the components are horizontally opened in the upper middle part of the base plate, U-shaped frames are installed at both ends of the base plate, and two groups of snap-in holes for fixing the clamping components are horizontally opened on the U-shaped frame. The snap-in grooves can be used to place multiple groups of placement plates as needed to improve the practicality of the branch structure.

[0008] Preferably, the placement component includes a clamping block, a placement plate, a vertical plate, a connecting shaft, a pressure plate and a spring, and the clamping block is horizontally provided with two groups, and a placement plate is installed at the upper ends of the two groups of clamping blocks, and an arc groove for placing the optical fiber is opened in the middle of the placement plate, and vertical plates are symmetrically installed at the edges of both sides of the upper end of the placement plate, and a connecting shaft is installed at the upper end of the vertical plate, and the pressure plate is rotatably connected to the vertical plate through the connecting shaft, and a spring fixedly connected to the vertical plate is installed at the lower end of the pressure plate, and a spring damper is installed inside the spring. The clamping block drives the placement plate to be fixedly clamped with the bottom plate through the clamping groove, and multiple groups can be placed as needed for easy use. Then the optical fiber is placed on the pressure plate through the strip groove, and then the optical fiber is pressed downward. The pressure plate is subjected to force to rotate downward through the connecting shaft and the vertical plate, and the spring is contracted under force, and the optical fiber reaches the placement plate. Finally, the spring rebounds, driving the pressure plate to rotate upward, so that the pressure plate returns to its original position, thereby limiting the optical fiber to avoid displacement of the optical fiber. In this way, multiple optical signals can be merged into one.

[0009] Preferably, the clamping assembly includes a square telescopic sleeve, a clamping column, a first pin, a square telescopic column, a first arc-shaped telescopic sleeve 405, a first arc-shaped telescopic sleeve, a strip telescopic sleeve, a strip telescopic column, a second pin, a second arc-shaped telescopic sleeve, a first annular module and a second annular module. A clamping column is installed at the bottom of the square telescopic sleeve, and the clamping column drives the square telescopic sleeve to be positioned and connected with the U-shaped frame through the clamping hole. The inner sleeve of the square telescopic sleeve is provided with a square telescopic column, and a first pin is provided at the connection between the square telescopic sleeve and the square telescopic column. The clamping column drives the square telescopic sleeve to be positioned and connected with the U-shaped frame through the clamping hole, and then the optical fiber is passed through the middle of the first arc-shaped telescopic column.

[0010] Preferably, two groups of first annular modules are arranged transversely, and two groups of second annular modules are arranged transversely between the two groups of first annular modules. The first annular module and the second annular module are arranged in the same manner.

Four groups of first arc-shaped telescopic columns are arranged around, and a second arc-shaped telescopic sleeve and a first arc-shaped telescopic sleeve 405 for fixed connection with the square telescopic column are connected between each two groups of first arc-shaped telescopic columns. Then, through the adjustment of the first pin and the second pin, the square telescopic column and the strip telescopic column move transversely along the square telescopic sleeve and the strip telescopic sleeve. During this process, the first arc-shaped telescopic column shrinks along the first arc-shaped telescopic sleeve 405 and the second arc-shaped telescopic sleeve until they fit the optical fiber to fix the position of the optical fiber.

[0011] Preferably, a strip telescopic sleeve is provided between the first annular module and the second annular module, and strip telescopic columns are provided inside each of the two ends of the strip telescopic sleeve, and the strip telescopic column is fixedly connected to the first arc-shaped telescopic sleeve 405, and a second pin is provided at the connection between the strip telescopic sleeve and the strip telescopic column, and holes for the first pin and the second pin to pass through are provided on the square telescopic column and the strip telescopic column, and then the first pin and the second pin pass through the holes to fix the position of the square telescopic column and the strip telescopic column. In this way, one optical signal can be divided into multiple ones.

[0012] Beneficial effects of the utility model:

[0013] 1. According to the previous use of fiber optic connection boxes, when multiple fiber pigtails share a collection point, signal attenuation and interference may occur, especially in high-speed data transmission or long-distance transmission, which may affect network performance and stability. The difference is that first, by pulling the handle, the flip cover is rotated open with the box body through the rotating column, and then the bottom plate is placed inside the box body. Then the clamping block drives the placement plate to be fixedly clamped with the bottom plate through the clamping groove. Multiple groups can be placed as needed for easy use. Then the optical fiber is placed on the pressure plate through the strip groove, and then the optical fiber is pressed downward. The pressure plate is forced to rotate downward through the connecting shaft and the vertical plate. At the same time, the spring is forced to shrink, and the optical fiber reaches the placement plate. Finally, the spring rebounds, driving the pressure plate to rotate upward, so that the pressure plate returns to its original position, thereby limiting the optical fiber to avoid displacement of the optical fiber. In this way, multiple optical signals can be merged into one.

[0014] 2. After placement, the snap-in column drives the square telescopic sleeve to be positioned and connected with the U-shaped frame through the snap-in hole, and then the optical fiber is passed through the circular hole and the middle of the first arc-shaped telescopic column. Then, through the adjustment of the first pin and the second pin, the square telescopic column and the strip telescopic column move laterally along the square telescopic sleeve and the strip telescopic sleeve. In this process, the first arc-shaped telescopic column shrinks along the first arc-shaped telescopic sleeve 405 and the second arc-shaped telescopic sleeve until it fits the optical fiber to fix the position of the optical fiber. Then, the first pin and the second pin pass through the hole to fix the position of the square telescopic column and the strip telescopic column. In this way, one optical signal can be divided into multiple ones. After the optical fiber is placed, the flip cover is closed, and the heat flow can flow out through the heat dissipation hole to avoid the accumulation of heat flow inside the combination and affect the operation of the optical fiber.

[0024] When working, first pull the handle 106, and the flip cover 104 is rotated and opened with the box body 1 through the rotating column 103, then the bottom plate 201 is placed inside the box body 1, and then the clamping block 301 drives the placement plate 302 to be fixedly clamped with the bottom plate 201 through the clamping groove 202. Multiple groups can be placed as needed for easy use. Then the optical fiber is passed through the strip slot 102 and placed on the pressure plate 305, and then the optical fiber is pressed downward. The pressure plate 305 is forced to rotate downward through the connecting shaft 304 and the vertical plate 303.

Then, through the adjustment of the first pin 403 and the second pin 409, the square telescopic column 404 and the strip telescopic column 408 move laterally along the square telescopic sleeve 401 and the strip telescopic sleeve 407. In this process, the first arc-shaped telescopic column 406 shrinks along the first arc-shaped telescopic sleeve 405 and the second arc-shaped telescopic sleeve 410 until it fits the optical fiber to fix the position of the optical fiber. Then the first pin 403 and the second pin 409 pass through the hole to fix the position of the square telescopic column 404 and the strip telescopic column 408. This method can divide one optical signal into multiple ones. After the optical fiber is placed, the flip cover 104 is closed, and the heat flow can flow out through the heat dissipation hole 105 to avoid heat flow accumulation inside the combination and affect the operation of the optical fiber.

[0026] Through the above steps, after placement, the clamping column 402 drives the square telescopic sleeve 401 to be positioned and connected with the U-shaped frame 203 through the clamping hole 204, and then the optical fiber is passed through the middle of the round hole 101 and the first arc-shaped telescopic column 406.

In this process, the first arc-shaped telescopic column 406 shrinks along the first arc-shaped telescopic sleeve 405 and the second arc-shaped telescopic sleeve 410 until it fits the optical fiber to fix the position of the optical fiber. Then the first pin 403 and the second pin 409 pass through the hole to fix the position of the square telescopic column 404 and the strip telescopic column 408. This method can divide one optical signal into multiple ones. After the optical fiber is placed, the flip cover 104 is closed, and the heat flow can flow out through the heat dissipation hole 105 to avoid the accumulation of heat flow inside the combination and affect the operation of the optical fiber.
