In the present embodiment, the first connector31is the connection terminal.

In the present embodiment, the housing32has a support wall322located atop, a pair of first side walls323that are disposed spaced-apart in a front-rear direction and connected to the support wall322, and second side walls324disposed transversely and connected to the pair of first side walls323and the support wall322, the through hole321runs through the support wall322in a top-down direction, the connection portion311is exposed out of an upper surface of the support wall322, and the second connector22is disposed on an upper inner wall of the fitting groove21.

The first side walls323are arranged asymmetrically, and side edges of the circuit board33facing the inner walls of the first side walls323are also arranged asymmetrically. In the present embodiment, one of the first side walls323has a recess which is inwardly recessed and cooperates with a protrusion on the fitting groove21to fix the storage device2. As such, the hanging lug3and the circuit board33can be mounted conveniently to avoid a mounting error.

Certainly, in other embodiments, the through hole321can also be disposed on the first side wall323or the second side wall324, the connection portion311is exposed on an outer surface of the first side wall323or the second side wall324, and the second connector22only needs to be disposed in the fitting groove21at a position corresponding to the first side wall323or the second side wall324.

The housing32further has a shielding portion327formed on a side of the support wall322in a transverse direction and close to the storage device2, the support wall322is formed with an inner recess326that is recessed downward, and the connection portion311is located in a space formed by the inner recess326and the shielding portion327. As such, the first connector31is fixed more firmly, and furthermore, when the storage device2is mounted on the hanging lug3, the shielding portion327can shield the first connector31and the second connector22to increase the aesthetics.

The refrigerator door body further comprises a power supply line (not shown) electrically connected to the circuit board33, an end of the power supply line is provided with a socket, and the circuit board33is provided with a plug mated with the socket. As such, when the hanging lug3is damaged, it can be easily detached for replacement or maintenance.

Certainly, in other embodiments, the power supply line can also be directly connected to the first connector31or the circuit board33to power the second connector22. For example, the first connector31is a socket disposed at the end of the power supply line, and the second connector22is a plug mated with the socket. As such, the structure is very simple and the cost is low.

As shown inFIG.5throughFIG.7, in the present embodiment, the second side wall324has a plurality of positioning posts3241formed protruding from an inner wall thereof, the circuit board33has positioning holes331mated with the positioning posts3241, and then the circuit board33is fixed on the housing32by gluing or in a snap-fitting manner.
