During after installation, taking the fixed first circuit 21 as an example, the first circuit 21 includes a first sub-circuit 211 and a second sub-circuit 212, one end of the first sub-circuit 211 is connected to the external fan 2, the other end of the first sub-circuit 211 is connected to the first connection terminal 213, one end of the second sub-circuit 212 is connected to the driver 3, the other end of the second sub-circuit 212 is connected to the other end of the first sub-circuit 211 through the first connection terminal 213, and the first sub-circuit 211 and the second sub-circuit 212 are connected through the first connection terminal 213, so that the connection between the driver 3 and the external fan 2 is realized, and the driver 3 can drive the external fan 2 to work.

It will be appreciated that the second circuit is secured to the upper surface of the terminal cover 4 in the same manner and in the same manner as the first circuit 21.

The junction box cover 4 of the embodiment realizes the universality of the front loading and the rear loading of the vehicle-mounted air conditioner 1, reduces the production cost and the design cost of the junction box, and has the functions of protection and fixation and water resistance.

Therefore, the junction box cover 4 for the vehicle-mounted air conditioner provided by the embodiment can be universal when being mounted in front and behind the vehicle-mounted air conditioner, and has the advantages of low cost, convenience in use and waterproof and fireproof protection effects.
