Problems solved by technology

[0005] In actual use, a fuse is installed in the plug. During the power-on process, the fuse continuously generates heat, which makes the temperature of the plug gradually rise. Since the plug is mostly made of plastic, the plug is softened and deformed at high temperature, resulting in the structure of the plug. Deformation and loosening of the installation structure inside the plug, that is, the plug is prone to high temperature damage

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] like figure 1 As shown, a switch box for manual maintenance includes a plug 1 and a socket 2. For the fixing method between the plug 1 and the socket 2, please refer to the structure disclosed in Patent No. CN208637341U, and a fuse is installed in the plug 1. One end of the socket 2 is provided with a mounting groove 11, and a heat sink 4 is embedded and fixed in the mounting groove 11, and a heat dissipation fan 5 is fixed on the heat sink 4. When the fuse is energized to generate heat, the heat absorbed by the plug 1 is radiated to the heat sink. The cooling fan 5 guides the air flow to the cooling fin 4, and the flowing air will take away the heat absorbed by the cooling fin 4 to cool down the plug 1, that is, to avoid the high temperature melting of the plug 1.

[0034] like figure 2 and image 3 As shown, one side of the installation groove 11...

Abstract

The invention relates to a manual maintenance switch box, which comprises a socket and a plug. A mounting groove is formed in the end, away from the socket, of the plug, and a cooling fin is embeddedinto the mounting groove. A cooling fan is fixedly arranged at the end, away from the plug, of the cooling fin, and the cooling fan is used for blowing air to the cooling fin. When a fuse is powered on to generate heat, the heat absorbed by the plug is transferred to the cooling fin, the cooling fan guides the air flow to the cooling fin, and the flowing air takes away the heat absorbed by the cooling fin, so that the plug is cooled, and melting of the plug at high temperature is avoided.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a manual maintenance switch box. Background technique [0002] At present, the voltage used by electric vehicles is generally not less than 300V high-voltage electricity. In order to avoid the danger of electric shock caused by improper operation and the damage of electrical components caused by overload and short circuit, it is necessary to install a manual maintenance switch on the high-current trunk line of the car circuit. . The manual maintenance switch plays the role of protecting the power supply in the electric vehicle circuit. In case of emergency or battery maintenance and installation, the manual maintenance switch can be disconnected in time to cut off the current of the battery pack, effectively avoiding damage due to improper operation by maintenance personnel. The resulting electric shock. [0003] The existing Chinese patent number CN208637341U discloses a manu...
