Description

Electrical box

technical field

The utility model relates to the field of refrigeration equipment, in particular to an electrical box used for a refrigerator or a freezer.

Background technique

With the improvement of people's living standards, refrigerators are required to have more precise temperature control. Precise temperature control refrigerators generally use electric control boards (including chips) to control the temperature inside the refrigerator, also called computer refrigerators.

The electric control board is the core component of a computer refrigerator. It has a large volume, many plug-in ports and connecting wires, complex assembly, and is prone to fire after contact with water. Therefore, how to prevent water from contacting the electric control Safety issues such as fire and the convenience, simplicity and speed of installation need to be considered.

At present, the existing electrical box usually uses screws and buckles to fix the electric control board. However, after the electrical wire enters the electrical box, there is no reasonable structure to fix it, so the electrical wire is easy to move, the production efficiency is low, and the electrical box has no effective structure. Prevent water from entering the inside of the electrical box, which may cause safety problems such as fire. For example, Chinese patent application No. 97251425.2 discloses a system control board box, including a box body and a box cover. The system control board is installed in the box body. The box body has a system control wire slot and a power wire slot. Entering the box body, the power cord enters the box body through the power cord slot, the power cord is fixed on the power cord resistance block, and the power cord resistance block is fixed on the power cord slot. Since the control wire slot is opened on the top of the control board box, water can easily flow into the inside of the control board box through the gap, causing potential safety hazards; there is no buckle to fix the wires after they enter the control board box, which makes the wires easy to get out of the wire clamping slot, which is not conducive to installation, it is also easy to cause the wire to be damaged.
