[0002] An optical splitter, also known as a beam splitter, is one of the important passive components in an optical fiber link and is a fiber optic junction device with multiple input ends and multiple output ends. The optical splitter includes a housing and connection components arranged inside the housing. Among them, the housing of the optical splitter generally includes a box body and a box cover. The connection components are arranged inside the box body. After the wiring is completed, the box cover needs to be connected to the box body so that the inside of the box body is isolated from the outside, thereby achieving the purpose of protecting the internal connection components. Conventional optical splitters are mostly of an integrated design, and the disassembly and installation are relatively cumbersome. It is not easy for users to organize the cables inside the optical splitter. For this reason, many designers have proposed some box-type optical splitters that are convenient for installation. For example, the prior art: CN209624852U, an optical splitter; includes a box cover and a box body with a receiving cavity. The receiving cavity communicates with the outside through an open end located on the box body. The box cover is detachably arranged at the open end.

Fixing plate slots 202 are provided near the left and right sides of the top of the box lid 2, and a fixing plate 5 is installed in the fixing plate slots 202.

[0032] In this embodiment, the box lid 2 is placed on the lid support plate 101. The top of the box lid 2 is flush with the top of the box body 1. There are two sets of the back hook 203 and the back slot 103. The side hooks 3 are arranged at both ends of the box lid 2 through the movable shafts 301 protruding from both ends. There are four side hooks 3 in total, two at each end. Similarly, four side slots 102 are also provided on the box body 1 at the corresponding positions. The side hooks 3 are in an L shape, and the long sides are provided with extended hooks downward to hook on the side slots 102. Through the two sets of back hooks 203 and the four side hooks 3, the box lid 2 is fixed to the box body 1 and will not easily fall off from the box body 1. It will not open even when subjected to a small external impact. The side hooks 3 are movable. The two ends of the movable shaft 301 on the side hooks 3 are inserted into the box lid 2. The side hooks 3 can rotate around the movable shaft 301. When the short side of the side hook 3 tilts up, the hook at the long side will disengage from the side slot 102. When all four side hooks 3 are disengaged, the box lid 2 can be disengaged from the side slots 102. By inserting the fixing plate 5 into the fixing plate slots 202, the tilting of the side hooks 3 is restricted, thus preventing the side hooks 3 from falling off. When it is necessary to remove the box lid 2, only need to pull out the fixing plate 5 from the fixing plate slots 202. The restriction on the rotation of the side hooks 3 is released. Just squeeze the corresponding side slots 102 to squeeze off the side hooks 3, flip the box lid 2 backward, and then disengage the back hook 203 from the back slot 103 to remove the box lid 2.

[0038] In this embodiment, the cable baffle 105 can effectively prevent the cables entering the interior of the box body 1 from the connecting component 4 from being wound at the entrance. The cable baffle 105 extends backward to separate the cables at the entrance.

[0039] Among them, convex platforms are fixedly connected to both sides of the fixing plate 5.

[0040] In this embodiment, the convex platforms are located at the middle positions on both sides of the fixing plate 5, and grooves are also opened at the corresponding positions of the fixing plate slots 202. The convex platforms are inserted into the grooves. When the fixing plate 5 is inserted into the slots 202 and pushed to the bottom, the convex platforms and the grooves can prevent the fixing plate 5 from detaching from the slots 202 and play a limiting role on the side hooks 3.

[0041] Among them, connecting feet 107 are fixedly connected to the four corners at the bottom of the box body 1, and connecting feet 204 are fixedly connected to the four corners at the top of the box cover 2.

[0042] In this embodiment, a cylinder is provided at the top of the connecting foot 107, and a round hole is opened at the center position of the connecting foot 204. Moreover, the diameters of the cylinder and the round hole are the same. The cylinder can be inserted into the round hole.
