Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch casing which is easy to disassemble. Background Art

[0002] Switch means "switch" and 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. A network switch is a device for expanding a network, which can provide more connection ports in a sub-network so as to connect more computers. However, in the prior art, a plurality of fixing screws are usually installed on the switch housing, which requires the operator to remove them one by one. The removal operation is relatively cumbersome. When the screws are fixed tightly and the screw quality is poor, it is very easy for the screws to slip, making it difficult to remove the switch housing. Moreover, most of them do not have a heat dissipation function, so the switch will inevitably generate a lot of heat when in use, resulting in a short service life of the switch. Moreover, when the switch is not in use, if it is left for a long time, a lot of dust will inevitably enter the connection port, which can easily damage the switch. The utility model proposes a new solution to the above problems. Utility Model Content
