Embodiment 1

[0049] 3 is a terminal protection net, which surrounds the terminal 2 and is fixed on the outside of the airtight container 6 by welding. The terminal protection net 3 is formed by bending a flat steel plate, such as Figure 6 and Figure 8 As shown, there are: a base part 7 fixed to the airtight container 6; a support piece 8 formed by bending the lower edge of the base part 7 at a right angle; the upper ends of the left and right edges of the base part 7 and lower holding pieces 11, 11 formed by bending the left and right edges of the base portion 7 at substantially right angles in the same manner. In addition, 12 is a circular hole facing the terminal 2 .

[0050] In this case, the upper holding pieces 9 , 9 are located at the left and right upper corners of the terminal guard net, and the lower holding pieces 11 , 11 are located outside the upper holding pieces 9 , 9 . In addition, the ends of the lower holding pieces 11, 11 are gradually expanded and bent obliquely out...

Abstract

There is here disclosed a terminal protective device for a compressor to which a terminal cover can be attached and held stably. The terminal protective device comprises a terminal fence fixed to the outer surface of a hermetically sealed vessel so as to surround a terminal attached to the hermetically sealed vessel, and a terminal cover attached to the terminal fence so as to cover the terminal. The terminal cover has the shape of a substantially rectangular box and is held on its upper or lower surface as well as right and left surfaces by the terminal fence.

Description

technical field [0001] The present invention relates to a terminal protection device for protecting terminals provided on a compressor airtight container, a compressor equipped with the terminal protection device, and a cooling storage. Background technique [0002] Conventionally, a compressor constituting a refrigeration device such as a cooling storage room is composed of an airtight container, an electric element and a compression element installed in the airtight container, and a device for supplying power to the electric element or operating control is provided outside the airtight container. terminals. An overload relay, a starter relay, etc. are attached to the terminal, and in order to constitute a charging unit, it is necessary to protect it with a resin terminal cover (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Application Laid-Open No. 6-121485 [0004] In this case, a terminal guard net made of steel plate is mounted ...
