せる再導通の危険性が大である。 By the way, in the operation of an alloy type temperature fuse, after the fuse element is blown at a predetermined temperature, an arc is generated until the interval between the fuses reaches a predetermined insulation distance. However, in conventional alloy type temperature fuses, the isolation speed of the blown fuse element is not very high, the arc duration is quite long, and there is a great risk of reconduction due to flux carbonization.
(考案の目的)
本考案の目的は、アーク持続時間を短縮できる
合金型温度ヒユーズを提供することにある。(Objective of the invention) An object of the invention is to provide an alloy type temperature fuse that can shorten the arc duration.

する構成である。(Structure of the invention) The alloy type temperature fuse according to the invention uses a low melting point metal for the fuse element and coats a flux on the low melting point metal.
This structure is characterized by adding a sublimable substance to the flux.
(実施例の説明) 以下、図面により本考案を説明する。(Explanation of Examples) The present invention will be explained below with reference to the drawings.

ある。 In the figure, 1 is a low melting point metal as a fuse element. 2, 2 is a lead conductor,
It is connected to a low melting point metal by welding. 3 is a flux, which is mainly composed of pine resin and has a sublimable substance added thereto. 4 is a protective tube, such as a ceramic tube. Reference numerals 5 and 5 designate a sealing material, such as epoxy resin, for sealing between the protective tube and the lead conductor.

持続時間を短縮できる。 In the above alloy type temperature fuse, when the low melting point metal is fused, an arc is generated in the gap between the fused fuses, but the sublimate in the flux is rapidly vaporized by the arc heat, and the vaporization pressure accelerates the fused gap. Since the arc is expanded to , the arc duration can be shortened accordingly.

Fluxes with a vapor pressure of 25 mmHg or higher at 150°C can be used, and the amount added to the flux is usually 5 to 60% by weight.
It is. An example of a flux formulation containing a sublimable substance is pine resin: 55 parts, naphthalene dicarboxylic acid:
40 parts, cyclohexylamine hydrochloride: 5 parts.
