[0002] The progress of society makes communication products an essential tool in people's life and work. In order to transmit communication signals to remote communication products, it is necessary to pass through a nearby signal base station and transmit them to the remote unit of an optical fiber repeater for communication signal amplification and coverage through a remote optical fiber, and then decode and amplify through the remote unit of the optical fiber repeater, and convert the signal back into a wireless communication signal and emit it.

[0003] However, for the operation of the remote unit of the optical fiber repeater, firstly, it needs a working power supply, and secondly, it needs to lead out a pigtail after splitting the optical fiber signal and then enter the equipment. The prior art often separately accesses the equipment, that is, the optical fiber access and the power supply access are separately and independently connected to the equipment. Moreover, as a stand-alone outdoor device, the remote unit of the optical fiber repeater is not moisture-proof, lightning-proof, dust-proof, and has no grounding treatment. Summary of the Invention

[0004] The purpose of the utility model is to overcome the defects of the above-mentioned prior art and provide a front-end equipment box of an improved remote unit of an optical fiber repeater.

[0005] The utility model adopts the following technical scheme:

[0006] A front-end equipment box of an improved remote unit of an optical fiber repeater, comprising a hollow box body composed of a box body and a box cover. The box cover is hinged to the box body 1, and is opened and closed by a support rod with one end hinged to the box cover and the other end slidable in a chute of a frame on one side of the box body. A PVC wire groove is arranged at the bottom of the box body; an optical fiber containing a remote base station signal from the outside is connected to an optical fiber splitter box fixed in the box body through an inlet at the bottom of the box body. A surge protector and a backup protection switch for the surge protector are fixedly arranged in the box body and are connected to an external power supply through a power inlet in the box body. A lightning protection grounding bar is connected to the surge protector; an arc-shaped waterproof structure for preventing external water sources from entering is arranged between the box body and the box cover;

[0007] The described arc-shaped waterproof structure is composed of an upper arc-shaped plate on the box cover, a lower arc-shaped plate, an upper arc-shaped plate on the frame of the box body, and a lower arc-shaped plate on the frame. The frame is fixed on one side of the box body. The upper arc-shaped plate on the frame is fixed on the top edge of the frame, and its lower arc faces the inside of the box body. The lower arc-shaped plate on the frame is fixed on the bottom edge of the frame, and its upper arc faces the inside of the box body. The upper arc-shaped plate on the box cover is fixed at the position corresponding to the upper arc-shaped plate on the frame on the box cover, and the arc is consistent with the arc facing the upper arc-shaped plate on the frame. The lower arc-shaped plate on the box cover is fixed at the position corresponding to the lower arc-shaped plate on the frame on the box cover, and the arc is consistent with the arc facing the lower arc-shaped plate on the frame.

[0008] The length of the vertical projection of the upper arc-shaped plate on the frame is greater than the length of the vertical projection of the upper arc-shaped plate, and the length of the vertical projection of the lower arc-shaped plate on the frame is greater than the length of the lower arc-shaped plate.

[0009] When the box cover is closed on the frame, the upper arc-shaped plate on the frame and the upper arc-shaped plate on the box cover are mutually attached, and the lower arc-shaped plate on the frame and the lower arc-shaped plate on the box cover are mutually attached.

[0010] A locking ear with anti-theft function is fixedly installed at the lower part of the box cover for mutual locking with the corresponding position of the box body.

[0011] A sealing joint with waterproof and dustproof functions is provided at the wire inlet of the bottom of the box body.

[0012] In the present utility model, various switches, lightning protection modules, and optical fiber splitters are integrated into one body and classified and sorted into the corresponding positions of the box body, making the inspection and testing process clear at a glance, and having good waterproof and dustproof functions.

The box cover 11 is hinged to the box body 1, and is opened and closed by a support rod 111 with one end hinged to the box cover 11 and the other end slidable in a chute of a frame 13 on one side of the box body 1. A PVC wire groove 12 is arranged at the bottom of the box body 1; an optical fiber containing a remote base station signal from the outside is connected to an optical fiber splitter box 4 fixed in the box body 1 through an inlet 7 at the bottom of the box body 1. A surge protector 2 and a backup protection switch 3 for the surge protector are fixed in the box body 1 and are connected to an external power supply through a power inlet 6 in the box body 1. A lightning protection grounding bar 5 is connected to the surge protector 2; an arc-shaped waterproof structure for preventing external water from entering is provided between the box body 1 and the box cover 11;

[0020] The arc-shaped waterproof structure is composed of an upper arc-shaped plate 113, a lower arc-shaped plate 114 on the box cover 11, a frame upper arc-shaped plate 131, and a frame lower arc-shaped plate 132 on the frame 13 of the box body 1. The frame 13 is fixed on one side of the box body 1. The frame upper arc-shaped plate 131 is fixed on the top edge of the frame 13, and its lower arc faces the inside of the box body 1. The frame lower arc-shaped plate 132 is fixed on the bottom edge of the frame 13, and its upper arc faces the inside of the box body 1; the upper arc-shaped plate 113 on the box cover 11 is fixed at a position on the box cover 11 corresponding to the frame upper arc-shaped plate 131, and the arc is the same as the arc facing the frame upper arc-shaped plate 131. The lower arc-shaped plate 114 on the box cover 11 is fixed at a position on the box cover 11 corresponding to the frame lower arc-shaped plate 132, and the arc is the same as the arc facing the frame lower arc-shaped plate 132;

[0021] The length of the vertical projection of the frame upper arc-shaped plate 131 is greater than the length of the vertical projection of the upper arc-shaped plate 113, and the length of the vertical projection of the frame lower arc-shaped plate 132 is greater than the length of the lower arc-shaped plate 114;
