Description

Technical Field

[0001] The utility model relates to the technical field of switches, and more specifically, to a sealing structure of a switch. Background Art

[0002] A switch means "switch", which is a network device used for forwarding electrical (optical) signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common ones include telephone voice switches and fiber optic switches. However, most traditional switches are fixed with bolts, and the sealing effect between the covers is not very good. In a humid environment, water vapor can easily enter the switch from the connection and cause damage to its internal components. In addition, the positions of the wiring ports are mostly open. At this time, the interfaces that are not connected to the lines are prone to dust and impurities, resulting in poor contact the next time it is used. At the same time, dust will corrode the electric shock shrapnel in the interface and affect normal use. Utility Model Content
