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

Minisize temperature controller

Technical field

The present invention relates to a kind of seal temperature relay, be applicable to civil electronic, household electrical appliances and space flight, aviation, weapons, boats and ships, electronics etc.

Background technology

Along with electrical equipment, the fast development of electronics industry, the purposes of temperature relay more and more widely, household electrical appliances and other electric appliance and electronic product all develop to the high performance mini direction, in space flight, aviation, weapons, fields such as boats and ships are particularly outstanding, requirement to temperature relay is more and more higher, not only want vibration resistance, shock-resistant, humidity, salt spray resistance, anti-low pressure, and it is reliable and stable, more want microminiaturized, existing temperature relay can't satisfy above-mentioned requirements because of reasons in structure, a kind of " wink dynamic formula seal temperature relay; it comprises long leg; short circuit stitch; glass insulator; base material; lining is for example disclosed in patent 200620109454.3, cover, positioning disk, mounting panel, packing ring, promote post, bimetal leaf, plain washer, quiet contact chip, moving contacting plate, insulation spacer, moving contacting plate adopts U type structure, promoting post packs in the respective aperture of positioning disk, bimetal leaf is installed in the fixed space of positioning disk and lining composition, above-mentioned each part is packed in the cover, and base material and cover be tightly connected, though its better performances, but complex structure, the manufacturing process difficulty is big, the price height, product to occupy the space too big, external diameter is more than 20 millimeters, can't realize microminiaturization, both at home and abroad active demand diameter in electronic component market is less than 10 millimeters microminiaturized thermostat, can resemble electric capacity, electronic components such as resistance are the same, can be directly installed on the integrated circuit.

Summary of the invention

In order to overcome the deficiency that existing temperature relay exists, goal of the invention of the present invention is to provide a kind of minisize temperature controller.

The technical scheme that the present invention takes is:

A kind of minisize temperature controller, comprise long binding post, the short circuit terminal, step cap, glass insulator, conducting strip, moving contact, insulation promotes post, bonding pad, the curved surface thermosensitive bimetal, shell, highlands such as long binding post and short circuit terminal upper end are fixed on the step cap by glass insulator, center at conducting strip is provided with centre bore, the upper end that insulation promotes post is sleeved in the centre bore of conducting strip, conducting strip is solidly fixed by bonding pad with the lower surface of long binding post, place, lower surface over against the short circuit terminal on conducting strip is provided with moving contact, the curved surface thermosensitive bimetal is placed in the enclosure, and placing insulation to promote the lower surface contact of post, shell is fixedlyed connected hermetically with step cap and is integral.

Further, be provided with silver static contact in the lower end of short circuit terminal.

Further, the distance between the lower end of long binding post and short circuit terminal is 0.5～1.5 millimeter, and the material of moving contact is an argent, and the external diameter of step cap is less than 10 millimeters.

Further, shell and step cap encapsulate under oxygen condition, guarantee no oxygen in the shell.

This minisize temperature controller is not only simple in structure, and dependable performance, long service life, overall dimension is little, and maximum gauge can be as daily electric capacity, resistance electronic component less than 10 millimeters, directly be welded on surface-mounted integrated circuit, realized the high-performance microization of thermostat, satisfied household electrical appliances and other electric appliance and electronic product high performance mini growth requirement, also can satisfy of the active demand of extraordinary fields such as space flight, aviation, weapons, boats and ships minisize temperature controller.
