Minisize temperature controller

Abstract

The invention discloses a minitype temperature control device, comprising a long post head, a short post head, a step cap, a glass insulator, a conducting strip, movable contacts, an insulating propelling column, a curved-surface thermosensitive bimetallic strip, an outer cover, wherein, the long post head and the short post head are fixed on the step cap by the glass insulator; the upper part of the insulating propelling column propels the conducting strip which is connected with the lower part of the long post head to form a whole body; the lower part of the short post head right faces the movable contacts on the conducting strip; the curved-surface thermosensitive bimetal strip is arranged in the outer cover and touches the lower end face of the insulating propelling column; the outer cover is hermetically fixed on the step cap into a whole. The minitype temperature control device is of simple structure, reliable performance, long service life, smaller size, and electric elements such as capacitors and resistances can be directly welded on an integrated circuit board so that the temperature control device is of high performance and micromation, the urgent demands on a high-performance minitype temperature control device are satisfied in special fields of electrical home appliance, space technology, aviation, weapon, ship, etc.

Description

technical field [0001] The invention relates to a sealed temperature relay, which is suitable for civil electronics, home appliances, aerospace, aviation, weapons, ships, electronics and the like. Background technique [0002] With the rapid development of the electrical and electronic industries, the use of temperature relays is becoming more and more extensive. Home appliances and other electrical and electronic products are developing in the direction of high-performance miniaturization, especially in aerospace, aviation, weapons, ships and other fields. The requirements are getting higher and higher, not only must it be resistant to vibration, impact, moisture, salt spray, and low air pressure, but also reliable and stable, and it must be miniaturized. The existing temperature relays cannot meet the above requirements due to structural reasons, such as In the patent 200620109454.3, an "instantaneous sealed temperature relay is disclosed, which includes a long terminal pi...

Problems solved by technology

[0002] With the rapid development of the electrical and electronic industries, the use of temperature relays is becoming more and more extensive. Home appliances and other electrical and electronic products are developing in the direction of high-performance miniaturization, especially in aerospace, aviation, weapons, ships and other fields. The requirements are getting higher and higher, not only must it be resistant to vibration, impact, moisture, salt spray, and low air pressure, but also reliable and stable, and it must be miniaturized. The existing temperature relays cannot meet the above requirements due to structural reasons, such as In the patent 200620109454.3, an "instantaneous sealed temperature relay is disclosed, which includes a long terminal pin, a short terminal pin, a glass insulator, a base material, a bushing, a cover, a positioning plate, a mounting plate, a gasket, a push column, a bimetal Sheet, flat washer, static contact piece, moving contact piece, insulating gasket, the moving contact piece adopts U-shaped structure, the push column is installed in the corresponding hole of the positioning plate, and the bimetallic piece is installed in the fixed space formed by the positioning plate and the bushing Inside, the above-mentioned parts are put into the cover, and the base material and the cover are sealed and connected. Although its performance is good, the structure is complicated, the manufacturing process is difficult, the price is high, the product occupies too much space, and the outer diameter is more than 20 mm. , can not achieve miniaturization, the domestic and foreign electronic component market urgently needs a miniaturized thermostat with a diameter of less than 10 mm, which can be directly installed on the integrated circuit like electronic components such as capacitors and resistors
