It is also used by Therefore, it is not necessary to directly connect the short-circuit connector 57 to the board power supply line 46 by one dedicated common power supply line, so that the number of power supply lines passing through the rear surface of the refrigerator main body 11 is further reduced.

The board power supply line 51a and the common relay power supply line 56 were connected via the male contact 53.
This eliminates the need to connect the common relay power supply line 56 to the board power supply line 51a via a dedicated relay connector, thereby reducing the number of relay connectors. In addition, since there is no need to connect the common relay power supply line 56 to the dedicated relay connector, the workability of connecting the common relay power supply line 56 is improved.

In the above embodiment, the common relay power supply line 56 is connected to the board power supply line 51a. However, the present invention is not limited to this. For example, the power supply board 46 may be connected to the connector housing 100 through the rear surface of the inner box 13. It may be connected directly to.

As is apparent from the above description, the refrigerator of the present invention has the following effects. According to the first aspect, a plurality of relay connectors are collectively connected to the power supply board via the short-circuit connector and the common power supply line. For this reason, the number of board power supply lines directly connected to the power supply board from the relay connector is reduced, so that the manufacturing time for connecting the board power supply line to the power supply board via the board connector, and the assembly of the board connector and the board power supply line The design effort for matching is reduced. In addition, a plurality of relay connectors and short-circuit connectors are housed in the same connector housing. This eliminates the need to pass the relay power line through the rear of the refrigerator main body, and only requires a few substrate power lines to be fixed to the rear surface of the refrigerator main body with tape. Wiring processing is simplified on both upper surfaces.

According to the second aspect, the plurality of relay power supply lines are short-circuited based on the insertion of the plurality of male contacts into the conductive portion of the short-circuit connector. It's easy. According to the third aspect of the present invention, a part of the common power supply line is also used as the substrate power supply line. Therefore, it is not necessary to directly connect the dedicated common power supply line to the substrate power supply line, so that the number of power supply lines passing through the rear surface of the refrigerator body is further reduced.

According to the fourth aspect of the present invention, the substrate power supply line and the common relay power supply line are connected via the contact. For this reason, it is not necessary to connect the common relay power supply line to the board power supply line via the dedicated relay connector, so that the number of relay connectors is reduced. In addition, since there is no need to connect the common relay power supply line to the dedicated relay connector, the connection workability of the common relay power supply line is improved.
