Abstract

A refrigeration appliance includes a storage compartment having opposite side walls and a rear wall therebetween. Each side wall includes a mounting portion. A shelf assembly is mounted on the storage compartment by the mounting portion and moves along a front-rear direction of the storage compartment limited by the mounting portion. The shelf assembly includes at least two first conductive terminals, and the first conductive terminal is located at a rear portion of the shelf assembly. A light source assembly on the shelf assembly includes a circuit substrate and a light source on the circuit substrate. A power supply portion located at a rear portion of the storage compartment supplies power to the light source and includes power supply terminal units on the rear wall close to corresponding side walls. The first conductive terminal maintains electrical connection with the power supply terminal unit due to the mounting portion.

First claim

What is claimed is:

1 . A refrigeration appliance, comprising:
a storage compartment having a pair of oppositely-disposed side walls, a rear wall disposed between said side walls, a front-rear direction and a rear portion, each of said side walls including a respective mounting portion; a shelf assembly mounted on said storage compartment by said mounting portions, said shelf assembly configured to carry out a movement along said front-rear direction being limited by said mounting portions, said shelf assembly including at least two first conductive terminals, and said at least two first conductive terminals being located at said rear portion; a light source assembly including a circuit substrate and a light source located on said circuit substrate, said light source assembly being disposed on said shelf assembly; a power supply portion located at said rear portion of said storage compartment for supplying power to said light source, said power supply portion including power supply terminal units each disposed in a vicinity of a respective one of said side walls, said power supply terminal units being disposed on said rear wall, and each of said at least two first conductive terminals maintaining electrical connection with said respective power supply terminal units by said mounting portions; and a second conductive terminal connected to said circuit substrate; said at least two first conductive terminals and said second conductive terminal being plugged and connected along a direction perpendicular to said circuit substrate; said second conductive terminal being located on a first side of said circuit substrate facing away from said rear wall; and said at least two first conductive terminals being connected to said second conductive terminal through said circuit substrate.

2 . The refrigeration appliance according to claim 1 , which further comprises an elastic member located in said shelf assembly, said at least two first conductive terminals each maintaining electrical connection with a respective one of said power supply terminal units under action of said elastic member.

3 . The refrigeration appliance according to claim 2 , wherein said elastic member is one of at least two elastic members, and each of said at least two first conductive terminals includes a respective one of said at least two elastic members.

4 . The refrigeration appliance according to claim 3 , wherein each of said at least two first conductive terminals includes a terminal base and a terminal head movable relative to said terminal base, and each of said terminal heads abuts against a respective one of said power supply terminal units under action of a respective one of said elastic members.

5 . The refrigeration appliance according to claim 4 , wherein each of said at least two first conductive terminals includes a respective one of said at least two elastic members located between said terminal base and said terminal head, and said at least two elastic members are adapted to apply a force acting toward a respective one of said power supply terminal units to said terminal head, causing said terminal head to abut against said power supply terminal unit.

6 . The refrigeration appliance according to claim 4 , wherein said terminal base has a hollow tube shape, and said terminal head is inserted into said terminal base and adapted to move along said terminal base.

7 . The refrigeration appliance according to claim 4 , which further comprises a second conductive terminal disposed on said circuit substrate, said terminal base being electrically connected to said second conductive terminal.

8 . The refrigeration appliance according to claim 1 , wherein said first conductive terminal is perpendicular to said circuit substrate.
