Abstract
The invention relates to an Ethernet multi-serial-port switch case, which comprises a case body, supporting legs, a dustproof blocking net, a draught fan, a connecting air pipe, a case cover, a fixingcase, a connecting pipe, a rectangular case, a sliding block, a spring, a U-shaped rod, a sliding rail case, a circular sliding block, a connecting block, a fixing frame, a threaded rod, a circular pressing piece, a fixing plate, a limiting inserting rod, an installing plate, fixing lug plates, rectangular insert blocks and a second threaded rod. The beneficial effects of the invention are that:the product is suitable for large-scale production; the equipment is reasonable in structure, convenient use, heat dissipation effect is good, through the heat dissipation structure, the air circulation speed in the inner cavity of the case can be increased, the situation that the temperature is too high due to heat accumulation in the inner cavity of the case is avoided, meanwhile, the heat dissipation structure can conduct dust removal and dehumidification on air entering the inner cavity of the case, dust accumulation or high humidity in the case is avoided, and then the service life of a switch is prolonged.
Description
technical field [0001] The invention relates to a switch box, in particular to an Ethernet multi-serial port switch box, and belongs to the technical field of switch box applications. Background technique [0002] Switch (Switch) means "switch" and is a network device used for electrical (optical) signal forwarding. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switches are Ethernet switches. Other common ones are telephone voice switches, fiber optic switches, etc. [0003] The switch is usually installed in the corresponding switch case. The traditional switch case usually uses a fan for heat dissipation, and there are several vents on the outside. Although this heat dissipation method is simple in structure, it will bring dust and moisture in the external air into the case. , affecting the service life of the switch. Therefore, an Ethernet multi-serial port switch chassis is proposed in view of th...
