Abstract:
1. An electrical connection box comprising: a base cover having a plurality of first openings; a top cover having a plurality of second openings, each of which is configured to connect to a corresponding first opening to form an outside jack for an output DC socket and thereby form a plurality of jacks; a main PCB board; an input DC socket located on said PCB board; a plurality of output DC sockets located on said PCB board, each of the output DC sockets corresponding to one of the jacks; a plurality of short circuit protectors located on said PCB board, each said short circuit protector being connected to each said output DC socket in parallel, each said short circuit protector comprising a triode having a collector and a base, and a constant voltage diode having an anode and a cathode, wherein the anode of the constant voltage diode is connected to the collector of the triode, and the cathode of the constant voltage diode is connected to the base of the triode; a thermal protector located on said PCB board; and a heat transmitter being configured to cover said input DC socket, output DC sockets, short circuit protectors and thermal protector; wherein said heat transmitter being configured to concentratively transfer heat of said input DC socket, output DC sockets, short circuit protectors to said thermal protector, said thermal protector being configured to cut off or resume power to all output circuits according to temperature change of the thermal protector in response to the heat transferred thereto via the heat transmitter; and wherein said main PCB board, input DC socket, output DC sockets, short circuit protectors and thermal protector are arranged between said base cover and top cover.
