Description

Technical Field

[0001] The present application relates to the technical field of optical fiber junction boxes, and in particular to an optical fiber junction box. Background Art

[0002] Fiber optic sensing technology is a new sensing technology that has developed along with the development of optical fiber and fiber optic communication technology. There are two main types of fiber optic sensing technology on the market: one is to use optical fiber directly as a sensor, and the other is to use a grating-based sensor. Fiber optic sensors are essentially different from electrical-based sensors. Fiber optic sensors use light as a carrier of sensitive information and optical fiber as a medium for transmitting sensitive information. They are widely used due to their unique characteristics. At present, before laying some pipes that need to be insulated in the ground, optical fibers are often laid on pipes wrapped in insulation sleeves to monitor the temperature of the pipes in real time to ensure that the insulation sleeves or pipes can be discovered in time when they are damaged. However, after the optical fiber is connected to the optical fiber junction box, the thermal expansion and contraction of the earth often causes the optical fiber connector to fall off the optical fiber junction box, which reduces the stability of the optical fiber and brings a bad user experience. Utility Model Content

However, after the optical fibers are connected to the fiber optic junction box, the thermal expansion and contraction of the earth often causes the optical fiber connectors to fall off the fiber optic junction box, reducing the stability of the use of the optical fiber.

[0005] The present application provides an optical fiber junction box, comprising a housing, a sealing cover, an adapter, a rubber block and an anti-drop mechanism, wherein the adapter and the rubber block are both fixedly installed in the housing;

[0006] The sealing cover is fixed on the upper surface of the housing, and the anti-dropping mechanism is installed in the housing. The anti-dropping mechanism is provided to prevent the optical fiber connector from falling off from the adapter.

[0007] In one embodiment of the present application, a sealing gasket is further included, and the sealing gasket is arranged between the shell and the sealing cover.

[0010] In one embodiment of the present application, a plurality of the rubber blocks are provided, the number of the rubber blocks is the same as the number of the wire holes, and the rubber blocks and the sockets of the adapter are provided correspondingly.

[0011] In one embodiment of the present application, the anti-slip mechanism includes a first clamping block, a second clamping block, a threaded rod and a nut, the first clamping block is fixed in the shell, the threaded rod passes through the first clamping block and the second clamping block at the same time, and the nut is threadedly sleeved on the threaded rod.

[0012] The beneficial effects of the present application are as follows: the present application obtains an optical fiber junction box through the above-mentioned design. When in use, the optical fiber connector is inserted into the shell through the wire hole, and is finally inserted into the adapter through the rubber soft block and the first clamp block, and the optical fiber cable is ensured to be in a loose state on the rubber soft block. The nut is rotated to make the second clamp block approach the first clamp block, and the first clamp block and the second clamp block clamp and fix the optical fiber, effectively preventing the optical fiber connector from falling off from the adapter. Even if a section of the optical fiber cable is pre-stored in the shell, the sealing gasket and the sealing cover are finally installed on the shell. The optical fiber cable adapts to the thermal expansion and contraction of the earth by squeezing the rubber soft block. The optical fiber junction box uses the rubber soft block to pre-store a section of optical fiber cable in the shell to adapt to the thermal expansion and contraction of the earth, and fixes the optical fiber cable through the second clamp block and the first clamp block, ensuring that the optical fiber connector will not fall off from the adapter, thereby improving the stability of optical fiber use and bringing a better user experience.

[0022] The sealing cover 130 is fixed on the upper surface of the housing 110, and the anti-slip mechanism 180 is installed in the housing 110. The anti-slip mechanism 180 includes a first clamping block 181, a second clamping block 182, a threaded rod 183 and a nut 184. The first clamping block 181 is fixed in the housing 110, and the threaded rod 183 passes through the first clamping block 181 and the second clamping block 182 at the same time. The nut 184 is threadedly sleeved on the threaded rod 183. The arrangement of the first clamping block 181 and the second clamping block 182 facilitates the fixing of the optical fiber, and effectively prevents the optical fiber connector from being adapted. The anti-drop mechanism 180 prevents the optical fiber connector from falling off the adapter 160, and also includes a sealing gasket 120, which is arranged between the housing 110 and the sealing cover 130. The setting of the sealing gasket 120 improves the sealing between the housing 110 and the sealing cover 130. The housing 110 is provided with a wire passing hole 140, and a plurality of wire passing holes 140 are arranged linearly and equidistantly on the housing 110. The setting of the wire passing holes 140 facilitates the insertion of the optical fiber connector into the housing 110.

[0023] Specifically, the working principle of the optical fiber junction box is as follows: when in use, the optical fiber connector is inserted into the housing 110 through the wire hole 140, and finally inserted into the adapter 160 through the rubber soft block 170 and the first clamping block 181, and the optical fiber cable is ensured to be in a loose state on the rubber soft block 170, and the nut 184 is rotated to make the second clamping block 182 approach the first clamping block 181, and the first clamping block 181 and the second clamping block 182 clamp the optical fiber to effectively prevent the optical fiber connector from falling off from the adapter 160, even if the optical fiber cable is in the housing 110, and finally the sealing gasket 120 and the sealing cover 130 are installed on the housing 110. The optical fiber cable adapts to the thermal expansion and contraction of the earth by squeezing the rubber soft block 170. The optical fiber junction box uses the rubber soft block 170 to pre-store a section of optical fiber cable in the housing 110 to adapt to the thermal expansion and contraction of the earth, and fixes the optical fiber cable by the second clamp block 182 and the first clamp block 181 to ensure that the optical fiber connector will not fall off from the adapter 160, thereby improving the stability of optical fiber use and bringing a better user experience.
