Abstract
The utility model relates to a thermal protector, in particular to a mini thermal protector. The thermal protector is provided with a casing and a thermal protector inner core; the thermal protector inner core is an integral structure formed by riveting a fixed plate component and a fixed seat; the fixed plate component is provided with a fixed plate, a bimetal strip and a moving contact; the moving contact is welded at one end of the bimetal strip, the other end is welded together with the fixed plate; and the static contact is connected with the fixed seat into a whole through injection molding. The thermal protector has the advantages of simple design, fully used space, compact structure and smaller volume; because the bimetal strip is provided with an arc groove, the temperature influence on the bimetal strip can be dispersed, and the service life is long; and because a dummy club for adjusting the position of the bimetal strip is arranged on the casing, the adjustment precision is ensured, and the positioning is accurate.
Description
Technical field
The utility model relates to a kind of thermal protector, especially a kind of miniature thermal protector.
Background technology
At present, most of thermal protectors all are applied on the overcurrent, overtemperature protection of electric elements such as motor, warmer, ballast, electric tool, but existing these bimetallic thermal protectors and other thermal protector volume is big, useful life short; Because its volume is big, is inconvenient to be installed on narrow and small position or is inlaid on the product; Locate inaccurately, insensitive to the hot benefit reaction of temperature, electric current,, overcurrent protection overheated to product be safety, reliable inadequately.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of new miniature thermal protector, its compact conformation, the convenient installation, the problem that solves that existing bimetallic thermal protector volume is big, the life-span short, the location is inaccurate etc.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of miniature thermal protector; have shell and thermal protector inner core; the integral body that described thermal protector inner core is made up of fixed head assembly and holder riveted joint; described fixed head assembly has moving contact, bimetal leaf and fixed head; bimetal leaf one end is welded with moving contact; the other end and fixed head weld together, and the fixed contact that is connected as a single entity by injection moulding is arranged on the holder, and moving contact and fixed contact are oppositely arranged.
Holder has the ship shape structure, conveniently forms the inner space of relative isolation with fixed head riveted joint back, can place the bimetal leaf assembly.The bimetal leaf assembly comprises bimetal leaf and the superincumbent moving contact of welding.
Be comparable on the bimetal leaf with end both sides of fixed head welding and be provided with identical arc groove.Arc groove can disperse bimetal leaf and fixed head welding back to the bimetal leaf Temperature Influence.
Fixed head is provided with the boss of adjusting the bimetal leaf position, established boss when described boss is the fixed processing plate.Be that boss is processed to form with the fixed head unification, rather than after fixed head assembly and holder riveted joint, reprocess, the adjustment precision of boss guaranteed to the bimetal leaf position.
The beneficial effects of the utility model are that miniature thermal protector adopts fixed head assembly and holder riveted joint to form integral product, reduces operation, makes compact conformation, smaller volume; Holder has the ship shape structure, can make full use of the space and place the bimetal leaf assembly; Bimetal leaf has two arc grooves, can disperse the temperature effect to bimetal leaf, life-saving; Shell is provided with the boss of adjusting the bimetal leaf position, has guaranteed the adjustment precision, accurate positioning.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. fixed head, 2. holder, 3. bimetal leaf, 4. moving contact, 5. fixed contact, 6. arc groove, 7. boss.
Embodiment
As shown in Figure 1; a kind of miniature thermal protector; have shell and thermal protector inner core; the integral body that described thermal protector inner core is made up of fixed head assembly and holder 2 riveted joints; described fixed head assembly has moving contact 4, bimetal leaf 3 and fixed head 1, and bimetal leaf 3 one ends are welded with moving contact 4, and the other end and fixed head 1 weld together; holder 2 is provided with the fixed contact 5 that is connected as a single entity by injection moulding, and moving contact (4) is oppositely arranged with fixed contact (5).
As shown in Figure 1, holder 2 has the ship shape structure, is convenient to form the inner space that isolates relatively behind the fixed head assembly staking, can place the bimetal leaf assembly.Described bimetal leaf assembly comprises bimetal leaf 3 and the superincumbent moving contact 4 of welding.
As shown in Figure 2, be comparable to end both sides of welding on the bimetal leaf 3 and be provided with identical arc groove 6 with fixed head 1.Arc groove 6 can disperse bimetal leaf 3 and fixed head 1 to weld the back to bimetal leaf 3 Temperature Influence.
As shown in Figure 2, fixed head 1 is provided with the boss 7 of adjusting bimetal leaf 3 positions, established boss 7 when described boss 7 is fixed processing plate 1.
