Description

Technical Field

[0001] The utility model relates to the field of switch installation, in particular to a housing for an optical fiber switch. Background Technique

[0002] A switch is a network device for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes accessing the switch. The switch means "switch", and it can, according to the needs of transmitting information at both ends of communication, send the information to be transmitted to the corresponding route that meets the requirements through methods completed manually or automatically by equipment.

[0003] In order to protect the switch body, it is usually necessary to install the switch in a protective housing. However, due to the complex wiring in the network cable computer room, it is easy to accidentally pull the lines connected to the switch during manual maintenance, resulting in damage to the connection structure at the head of the line, thus loosening the network cable connection, and even pulling the line away from the switch, affecting the overall network use. Content of the Utility Model

[0004] The purpose of the utility model is to provide a housing for an optical fiber switch to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A housing for an optical fiber switch, including a protective housing and a moving plate. A communication groove is opened on one side of the protective housing. The lower part of the communication groove is circular, and the upper part of the communication groove is square. Two sets of lifting grooves are opened inside one side of the protective housing. Two sets of upper and lower control grooves communicating with the lifting grooves are opened inside the protective housing. A lifting block is slidably connected inside the lifting groove. A pressing block is fixedly connected between the two lifting blocks on both sides. The pressing block is slidably connected inside the control groove. A groove facing the communication groove is opened at the lower part of the control groove.

[0006] Preferably, two sets of embedding grooves are opened at the upper part of one side of the protective housing. Embedding pieces adapted to the embedding grooves are fixedly connected to both sides of the upper lifting block. A first threaded rod is threadedly connected inside the embedding piece.
