Abstract

The invention provides an arc preventive switch, which comprises a shell, an anode connector, a cathode connector, a switch connector, a delay circuit, a first end and a second end, wherein the anode connector and the cathode connector are arranged on one end face of the shell, the switch connector is connected with one of the anode connector and the cathode connector when the switch connector is pressed, the length of the anode connector and the cathode connector projecting over the end face is larger than that of the switch connector projecting over the end face, the delay circuit is connected between the anode connector and the cathode connector, the first end is connected with the switch connector, the second end is connected with the other of the anode connector and the cathode connector, and the first end and the second end are connected with a direct-current power source. The arc preventive switch in an embodiment is simple in structure, low in cost and easy in realization.

Description

technical field [0001] The invention relates to the technical field of electrical equipment manufacturing, in particular to an arc-proof switch and a DC power supply device having the same, and more specifically, to a point-contact mechanical arc-proof switch. Background technique [0002] Arcing is easy to occur when the DC power supply interface is plugged and unplugged. Arc is a gas discharge phenomenon. The instantaneous spark generated by the current passing through some insulating medium (such as air) will have a very serious impact on various servers, computers and other electrical appliances that use DC power supply. Because the electric arc (or electric spark) will produce huge power, if no protective measures are taken, it will cause serious damage to the switching system and connected electrical appliances, and may also have serious consequences for the area around the switch, and even cause harm to people. [0003] Such as Chinese patent 03806653.x discloses a k...
