Description

Technical Field

[0001] This utility model relates to the field of fiber optic terminal boxes, and in particular to a rail-mounted fiber optic terminal box. Background Technology

[0002] Fiber optic terminal boxes are the termination points of optical cables. They are devices that split optical cables into individual optical fibers and are widely used in local telephone and rural telephone network systems, data transmission systems, and cable television.

[0003] Fiber optic terminal boxes in related technologies typically include a vertically arranged box body with an opening on one side and a cover on the opening side. A waterproof connector is located on the top side of the box body, a guide rail seat is located on the back side, and multiple fiber optic connectors are located on the front side.

[0004] Unscrew the compression cap on the waterproof connector and pass the fiber optic cable through the compression cap and the waterproof connector body to allow the fiber optic cable to enter the housing. Then, tighten the compression cap onto the waterproof connector body to secure the fiber optic cable. Next, connect the multiple fiber optic cables inside the cable to their respective fiber optic connectors, install the housing cover onto the housing, and then install the guide rail mount onto the guide rail of the external device. Finally, plug the external data connector into the fiber optic connector to achieve fiber optic cable splitting.

[0005] For some larger fiber optic terminal boxes, there are a lot of fiber optic connectors. In this case, it is necessary to split the two fiber optic cables. Therefore, two waterproof connectors are provided on the top side of the box to allow the corresponding fiber optic cables to pass through and to fix the corresponding fiber optic cables.

[0006] However, the two waterproof connectors are located on the top side of the box, meaning that the two fiber optic cables enter from the top side of the box. When the multiple fiber optic lines in the two fiber optic cables are connected to the corresponding fiber optic connectors, interference problems such as crossing and tangling can easily occur. This is not conducive to the wiring of the fiber optic cables by the staff and also poses a safety hazard, which needs to be improved. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rail-mounted fiber optic terminal box that can achieve two-sided cable entry, which is convenient for staff to lay fiber optic cables and reduces safety hazards.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a guide rail type fiber optic terminal box, including a box body and a box cover, wherein a guide rail seat is provided on the back side of the box body and a plurality of fiber optic connectors are provided on the front side, and waterproof connectors are provided on the top and bottom sides of the box body respectively. Two fiber optic cables can enter from the bottom and top sides of the box body respectively. The fiber optic cable entering from the top side of the box body can be connected to half of the fiber optic connectors located at the top position, and the fiber optic cable entering from the bottom side of the box body can be connected to the other half of the fiber optic connectors.

[0009] In a preferred embodiment, the present invention can be further configured such that: two sets of limiting cards are fixedly connected inside the box, and each set of limiting cards is used to clamp and limit the corresponding optical fiber cable.

[0010] In a preferred embodiment, the present invention can be further configured such that each set of limiting cards includes multiple pairs of elastic limiting pieces, each pair of limiting pieces having an arched structure with concave surfaces facing each other, and the optical fiber cable can be inserted between each pair of limiting pieces.

[0011] In a preferred embodiment, the present invention can be further configured as follows: a limiting plate is fixedly connected inside the box, the limiting plate is provided with multiple limiting notches, the multiple limiting notches are provided one-to-one with the multiple optical fiber connectors, and the multiple optical fiber lines in the two optical fiber cables can be inserted one-to-one into the corresponding limiting notches. A clamping plate is detachably connected to the limiting plate, the clamping plate is used to press and fix the optical fiber lines into the corresponding limiting notches.

[0012] In a preferred embodiment, the present invention can be further configured such that: fastening screws are threadedly connected to the four corners of the pressing plate, and fastening grooves are provided at the four corners of the limiting plate for the corresponding fastening screws to engage with the threads.

[0013] In a preferred embodiment, the present invention can be further configured such that: the pressing plate is provided with a plurality of clearance notches, the plurality of clearance notches are provided in a one-to-one correspondence with the plurality of limiting notches, and the clearance notches and the corresponding limiting notches together form a limiting hole for the optical fiber to pass through.

[0014] In a preferred embodiment, the present invention can be further configured such that the lid and the box body are connected by a plurality of locking screws.

[0015] In a preferred embodiment, the present invention can be further configured such that the guide rail base and the housing are connected by a pair of fastening bolts.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. Since the two fiber optic cables can enter from the bottom and top sides of the box respectively, the entry of the fiber optic cables is more flexible and effectively reduces the risk of interference such as crossing and tangling of multiple fiber optic lines in the two fiber optic cables. This not only makes it easier for staff to lay fiber optic cables, but also reduces safety hazards.

[0018] 2. Multiple limiting notches on the limiting plate separate multiple optical fibers in each optical fiber cable, reducing the risk of contact between adjacent optical fibers. This not only facilitates the wiring of optical fibers by staff, but also further reduces safety hazards. Attached Figure Description

A cover 2 is provided on the open side of the box body 1, and the cover 2 is connected to the box body 1 by multiple locking screws 3. A rail seat 4 is fixedly connected to the back side of the box body 1 by a pair of fastening bolts 5. Multiple fiber optic connectors 6 are fixedly connected to the front side of the box body 1. Waterproof connectors 7 are provided on the top and bottom sides of the box body 1, respectively.

[0026] Reference Figure 1 , Figure 2 One fiber optic cable is introduced through the waterproof connector 7 located on the top side of the box 1, and connected to half of the fiber optic connectors 6 located at the top. At the same time, the other fiber optic cable is introduced through the waterproof connector 7 located on the bottom side of the box 1, and connected to the other half of the fiber optic connectors 6. Then, the guide rail seat 4 is matched with the guide rail of the external equipment to realize the installation of the fiber optic terminal box.

[0027] Since the two fiber optic cables can enter from the bottom and top sides of the box 1 respectively, the entry of the fiber optic cables is more flexible and effectively reduces the risk of interference such as crossing and tangling of multiple fiber optic lines in the two fiber optic cables. This not only facilitates the wiring of fiber optic lines for staff, but also reduces safety hazards.

[0028] Reference Figure 2 , Figure 3 Two sets of limiting clips 8 are fixedly connected inside the housing 1. Each set of limiting clips 8 is used to clamp and limit the corresponding optical fiber cable to reduce the risk of interference between the two optical fiber cables. Each set of limiting clips 8 includes multiple pairs of elastic limiting pieces 81. Each pair of limiting pieces 81 has an arched structure with concave surfaces facing each other, and the optical fiber cable can be inserted between each pair of limiting pieces 81. In this embodiment, the limiting pieces 81 are made of elastic plastic. In other embodiments, other elastic materials may also be used.

[0029] Reference Figure 2 , Figure 4 A limiting plate 9 is fixedly connected inside the box 1. The limiting plate 9 is provided with multiple limiting notches 10. The multiple limiting notches 10 are set one-to-one with multiple fiber optic connectors 6, and the multiple fiber optic lines in the two fiber optic cables can be inserted into the corresponding limiting notches 10 one-to-one to separate the multiple fiber optic lines in each fiber optic cable and reduce the risk of contact between adjacent fiber optic lines.

[0030] Reference Figure 2 , Figure 4 A clamping plate 11 is detachably connected to the limiting plate 9. The clamping plate 11 is used to clamp and fix the optical fiber line within the corresponding limiting notch 10 to achieve the fixation of the optical fiber line. At the same time, the clamping plate 11 is provided with multiple clearance notches 12, which are provided one-to-one with the multiple limiting notches 10. The clearance notches 12 and the corresponding limiting notches 10 together form a limiting hole 13 for the optical fiber line to pass through, thereby improving the separation effect of the optical fiber line.
