Embodiment

[0052] The airtight terminal 10 of Embodiment 1 involved in the present disclosure is as figure 1 As shown, it includes: a metal base 11 of carbon steel with a plurality of through holes 100 provided for screw stop and three sealing holes arranged on a straight line; The lead 12 made of Cr-iron-based alloy; the insulating material 13 of borosilicate glass that hermetically seals the metal base 11 and the lead 12 ; and the heat insulator 14 . The heat insulator 14 is a coating that covers the surfaces of the metal base 11, the pins 12 and the insulating material 13, which are located on the inner side and come into contact with the refrigerant when the airtight terminal 10 is attached to the pressure-resistant container. , is made by HNBR.

[0053] A part of the insulator 14 is along the inner layer side ( figure 1 The surface of the lead 12 in (a)) extends to cover the lead 12 except the tip portion. The other part of the heat insulator 14 covers the entire surface of the i...

Embodiment 2

[0060] Since the airtight terminal 20 of the second embodiment uses EPDM for the heat insulator 24, it can satisfy refrigerant resistance, especially oil resistance to POE [polyol ester] oil. In addition, by using EPDM to increase the creepage distance between the inner metal base 21 and the pin 22 , tracking resistance, electrical insulation, and voltage resistance can be improved.

[0061] Such as image 3 As shown, after the pins are electrically connected to the motor housed inside the pressure-resistant container 35 where the air-tight terminal is installed, the air-tight terminal according to the present disclosure can be inserted into the terminal installation hole 36 of the pressure-resistant container 35, And carry out fastening and installation by screw 37 etc.

[0062] The lead of the hermetic terminal according to the present disclosure can have desired electroplating on the surface thereof. In addition, as long as the metal material which can be used for an airt...

Abstract

An airtight terminal (10) comprising: a metal base (11) having at least one sealing hole; a lead (12) inserted through the sealing hole in the metal base (11); an insulating material (13) that hermetically seals the metal base (11) and the lead (12); and a heat-insulating material (14) positioned on the inner side in a state in which the airtight terminal (10) is attached to the pressure-resistant container, said heat-insulating material (14) being provided on at least part of a surface of the airtight terminal (10) that is in contact with a refrigerant sealed inside the pressure-resistant container.

Description

technical field [0001] The present invention relates to an airtight terminal and a pressure-resistant container using the airtight terminal. Background technique [0002] The hermetic terminal hermetically seals the pin to the insertion hole of the ferrule or the metal base through the insulating material made of glass. The airtight terminal is used when supplying electric current to electrical equipment or components housed in an airtight container, or when taking out signals from the electrical equipment or components to the outside. For example, International Publication No. WO2010 / 117000 (Patent Document 1) discloses airtight terminals used in refrigerators and compressors of air conditioners. In the airtight terminal disclosed in Patent Document 1, a metal base is used, and the metal base includes: a top plate portion; a cylindrical portion extending downward from an outer peripheral end of the top plate portion; and a flange portion. , the flange part expands oblique...
