Technical Field

[0002] A box splitter is a network device used to distribute a physical signal line to multiple logical signal lines to achieve multi-channel signal forwarding and management. It usually consists of two parts: a host and a splitter. The host is connected to the signal source, and the splitter is connected to multiple transceivers. The host controls the splitter by sending control signals, thereby changing the path of the channel and routing the signal to different ports. The use of a box splitter is relatively simple. Usually, all devices need to be connected to the host and the splitter, and then configured and managed using control software.

[0003] After searching, Chinese patent announcement number: CN216248471U discloses an optical splitter with a wire harness anti-falling structure, which is provided with a positioning plate, a guide column and a spring. The operator sleeves the positioning plate on the surface of the wire, and then moves the guide column inside the guide sleeve to drive the positioning plate to dock with the lower box cover. Then the positioning plate is connected to the lower box cover through the guide column and the spring and the buckle form an elastic telescopic structure, so that the positioning plate is stable on the bottom surface of the lower box cover, thereby facilitating the fixing of the wire and preventing it from falling off.

[0004] In the above technical solution, the cable is prevented from falling off by using structures such as positioning plates, guide columns and springs. However, the cable lacks a double limiting function after being fixed, which reduces the cable's anti-falling degree and thus reduces the stability of the splitter. Therefore, a box-type splitter optical cable anti-falling mechanism is proposed to solve the above problem. Utility Model Content

The positioning component includes a rack 6, and the outer wall of the rack 6 is provided with a gear 7. The gear 7 serves as an auxiliary wheel. The rotation of the gear 7 can drive the ratchet 9 to rotate synchronously through the rotating shaft 8.
