Abstract
The utility model provides a temperature switch. The temperature switch comprises a detection housing, a motion housing and a switch housing sequentially, and is characterized in that the a bimetallic strip is disposed inside the detection housing; the bimetallic strip wraps one end of a valve stem, and the other end of the valve stem is extended into the motion housing and abuts against the input end of a valve block; springs are disposed between the input end of the valve block and the internal output end of the motion housing; contact switches are disposed at the output end of the switch housing; the inside of the switch housing is provided with a movable contact piece which can switch on the contact switches; the output end of the valve block abuts against a transmission connecting rod on the movable contact piece; and an elastic component is disposed between the movable contact piece and the contact switches. After the adoption of the above technical scheme, according to the deformation of the bimetallic strip at a certain temperature value, the valve block moves to drive the movable contact piece so that the contact switches are connected to form a closed circuit, that is, the temperature switch body forms a closed circuit. The temperature switch is simple in structure and low in production cost.
Description
Technical field
The utility model belongs to switchgear, is specifically related to a kind of temperature switch.
Background technology
Temperature switch is a kind of with the temperature switch of bimetal leaf as temperature-sensing element; during the electrical equipment normal operation; bimetal leaf is in free state; the contact is in closure/off-state; when temperature was increased to the operating temperature value, bimetallic element was heated and produces internal stress and rapidly action, the opened/closed contact; cut off/connect circuit, thereby play heat protective effect.To reset temperature be contact auto-closing/disconnections when degree gradually drops to, the recovery normal operating conditions.Be widely used in domestic electric appliance motor and electric equipment, such as motor for washer, air conditioner fan motor, transformer, ballast, electric heating appliance etc., but its inner transmission mechanism of existing temperature switch is relatively complicated, if temperature increase is too fast, then the too fast meeting of its transmission speed causes the damage of its temperature switch inside.
Summary of the invention
The utility model then provides a kind of simple in structure, sensitive temperature switch in order to solve the technical problem of mentioning in the background technology.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of temperature switch, comprise successively the detection housing, motion housing and switch case, it is characterized in that: be provided with bimetal leaf in the described detection housing, one end of a valve rod of described bimetal leaf parcel, the other end of valve rod extend in the motion housing and the input of a valve piece offsets, be provided with spring between the input of described valve piece and the motion enclosure interior output, the output of described switch case is provided with contact switch, switch case inside is provided with the movable contact flat that contact switch can be connected, the output of described valve piece and the kinematic link on the movable contact flat offset, and are provided with elastomeric element between movable contact flat and the contact switch.
Described elastomeric element is one to have flexible metallic laminas, and bending is arranged between contact switch and the movable contact flat.
Pour into silica gel between the fixing clearance of described contact switch and switch case.
After adopting above technical scheme: the deformation under certain temperature value causes according to bimetal leaf, and the valve piece moves the promotion movable contact flat, so that the contact switch path, i.e. and temperature switch body passage, it is simple in structure, and production cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of temperature switch, comprise successively and detect housing 1, motion housing 2 and switch case 3, detect in the housing 1 and be provided with bimetal leaf 4, one end of a valve rod 5 of bimetal leaf 4 parcels, the other end of valve rod 5 extend in the motion housing 2 and the input of a valve piece 6 offsets, be provided with spring 7 between the input of valve piece 6 and motion housing 2 internal output terminals, the output of switch case 3 is provided with contact switch 8, switch case 3 inside are provided with the movable contact flat 9 that contact switch 8 can be connected, kinematic link 10 on the output of valve piece 6 and the movable contact flat 9 offsets, be provided with elastomeric element 11 between movable contact flat 9 and the contact switch 8, elastomeric element 11 is one to have flexible metallic laminas, bending is arranged between contact switch 8 and the movable contact flat 9, can adopt sheet metal one end to be stuck on the contact switch 8 referring to the concrete bend mode of Fig. 1, then movable contact flat 9 is walked around in the bending of sheet metal mid portion, the other end of last sheet metal is stuck on the movable contact flat 9, pours into silica gel between the fixing clearance of contact switch 8 and switch case 3.
Operation principle of the present utility model: along with detected temperature change, bimetal leaf 4 beginning deformation, then slowly be with successively ovable valve stem 5 and valve piece 6 to move, when detected temperature arrives a certain critical value (such as 50 degrees centigrade), valve piece 6 promotion kinematic links 10 can make electrode and the electrode path on the contact switch 8, then the temperature switch path on its movable contact flat 9.
The beneficial effects of the utility model: the deformation under certain temperature value causes according to bimetal leaf, and the valve piece moves the promotion movable contact flat, so that the contact switch path, be the temperature switch body passage, it is simple in structure, has a plurality of drive links, can reduce the power that its transmission produces, production cost is low.
