[0002] The terminal box is the terminal connector of an optical cable. It has an optical cable at one end and a pigtail at the other. It is equivalent to a device that splits an optical cable into individual optical fibers. The user optical cable terminal box installed on the wall provides fiber-to-fiber fusion, fiber-to-pigtail fusion, and optical connector connection. It also provides mechanical and environmental protection for optical fibers and their components, and allows for proper inspection to maintain the highest standards of fiber management.

[0003] The ports of the terminal box are usually exposed on the terminal box panel. The port types are usually FC / SC / ST / LC, etc. When in use, you can directly connect to the port.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , in the embodiment proposed in the present application, there is: a terminal box protection structure, comprising a protective cover 2 arranged at a port insertion position 11 at the rear end of the terminal box 1, the protective cover 2 can be fixed at the rear end of the terminal box 1 (such as bolt fixing, etc.), a plurality of through holes 21 are respectively opened at the front end of the protective cover 2 corresponding to the port insertion position 11, a protective cover 3 is hinged at the plurality of through holes 21, a torsion spring 6 is provided at the hinge between the protective cover 3 and the front side of the protective cover 2, a clearance groove 31 is opened at the middle part of the front end of the protective cover 3 corresponding to the inserted cable 12, a clamping structure 4 for clamping the cable 12 is movably provided in the clearance groove 31, and a supporting block 5 matching therewith is respectively fixed at the plurality of clearance grooves 31 at the front side of the protective cover 2;

[0021] A protective cover is provided to fix the inserted cable through the clamping structure 4 when the cable is inserted. At the same time, the protective cover can protect the crystal head at the insertion position. When the cable is not inserted, the protective cover can cover the port insertion position to prevent dust from entering and affecting subsequent use. The overall design is simple and practical.

[0022] In another embodiment, see Figure 1-4 The clamping structure 4 includes a clamping plate 41 arranged in the give way groove 31, and the left and right sides of the give way groove 31 correspond to the clamping plate 41 respectively. The left and right ends of the clamping plate 41 are respectively provided with limit sliding blocks 42 slidably connected thereto corresponding to the limit sliding blocks 32. The side of the clamping plate 41 facing away from the support block 5 is inserted in the protective cover 3 and slidably connected thereto. The front side of the clamping plate 41 is laterally provided with a lifting plate 45 at one end facing the support block 5. When the clamping plate 41 slides toward the support block 5 until the limit sliding block 42 abuts against the side wall of the limit sliding groove 32, the clamping plate 41 just abuts against the support block 5.

[0023] When the cable is inserted, the protective cover is rotated along the hinge to the leakage hole, and the crystal head is inserted into the port insertion position. After insertion, the protective cover is reset, and the lifting plate is lifted before resetting. During the resetting process, the cable will be clamped in the limit groove, and then the lifting plate is pulled down to cooperate with the support block to clamp the cable in the limit groove;

[0024] A placement hole 43 is opened in the protective cover 3 on the side of the clamping plate 41 facing away from the support block 5, and a spring 44 is inserted in the placement hole 43. One end of the spring 44 abuts against the bottom of the placement hole 43, and the other end abuts against the side of the clamping plate 41 facing away from the support block 5; the setting of the spring can make the clamping plate have a certain clamping force, avoid the clamping plate from opening during the clamping process, and increase a certain degree of protective performance.

[0025] In this embodiment, the support block 5 includes a laterally arranged support plate 51, and a matching top block 52 is vertically arranged at the front side of the support plate 51 corresponding to the clearance groove 31. The top block cooperates with the clamping block to clamp the cable when the cable is inserted, and cooperates with the clamping block to close the clearance groove when the cable is not inserted, thereby achieving a protective effect (the support block in the accompanying drawing is only for schematic effect, and the top block here will not affect the insertion of the cable crystal head when it is specifically set).
