Description

Direct-insertion type bimetal temperature controller

Technical Field

The utility model belongs to the temperature controller field especially relates to a bimetal temperature controller of cut straightly type.

Background

The temperature controller is a series of automatic control elements which are physically deformed in a switch according to the temperature change of a working environment, thereby generating certain special effects and generating on or off actions. The bimetal temperature controller is a kick type temperature controller, the principle is that a bimetal sheet after temperature setting is used as a heat sensitive reaction component, heat generated when the temperature of a main part of a product rises is transferred to a bimetal wafer, the bimetal wafer rapidly acts when the temperature reaches an action temperature setting, and a contact is opened or closed under the action of a mechanism; when the temperature is reduced to the reset temperature, the bimetallic strip is rapidly restored to the original state, so that the contact is closed or disconnected, the purpose of connecting or disconnecting the circuit is achieved, and the circuit is controlled.

The bimetal temperature controller can be applied to various working environments, so that the waterproof and explosion-proof bimetal temperature controller is widely applied. However, the existing waterproof and explosion-proof temperature controller is connected with the application equipment through a wire, as shown in fig. 1, the installation is complex, and the wire connection cost is high.

SUMMERY OF THE UTILITY MODEL

In view of the above problem, the utility model provides a bimetal temperature controller of cut straightly type adopts the cut straightly terminal, has reduced wire connection cost, and it is convenient to install, the production of being convenient for.

In order to achieve the above object, the utility model adopts the following technical scheme:

an in-line bimetallic thermostat, comprising: the metal elastic piece assembly comprises an elastic piece, an elastic piece contact, a still piece and a still piece contact, wherein the elastic piece contact and the still piece contact are located on the elastic piece, the end cover is located at one end of the shell, the direct-inserting terminal is located at the other end of the shell, the support is fixed inside the shell and close to one side of the end cover, a push rod is fixed on the support, one end of the push rod pushes a disc, and the other end of the push rod pushes the elastic piece.

Preferably, the spring plate and the spring plate contact are riveted, and the static plate contact are riveted.

More preferably, the elastic sheet and the static sheet are respectively riveted on the shell through rivets.

More preferably, the in-line terminal is soldered to the rivet by a solder wire.

Preferably, the elastic sheet contact is in contact with the still contact at normal temperature, and the disc is deformed at high temperature and is pressed against the elastic sheet through the ejector rod, so that the elastic sheet contact is separated from the still contact.

Preferably, the expansion coefficient of the disc is greater than that of the metal dome assembly.

Preferably, the interior of the housing is potted with epoxy.

Compared with the prior art, the beneficial effects of the utility model are that:

the direct-insert type bimetal temperature controller adopts a direct-insert terminal connection mode, the terminals are communicated with the metal elastic sheet assembly, the process is simple, automatic batch production is facilitated, meanwhile, the number of wires and connectors is reduced, and the cost is reduced.

Detailed Description

For a better understanding of the present invention, the contents of the present invention will be further clarified below with reference to the accompanying drawings and examples, but the present invention is not limited to the following examples.

Examples

In the description of the present invention, it is to be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inner", "outer", etc. are all the directions or positional relationships shown on the drawings, and the objects are only for convenience of description of the present invention and simplification of description, and do not indicate or imply that the parts indicated must have a specific direction, be constructed and operated in a specific direction, and thus, are not to be construed as limiting the present invention.

As shown in fig. 2, an in-line bimetal thermostat is characterized by comprising: casing 6, end cover 10, support 7, cut straightly terminal 11 and be fixed in the inside metal shrapnel subassembly of casing 6, the metal shrapnel subassembly includes shell fragment 2 and the shell fragment contact 1 that is located shell fragment 2, still 4 and the still contact 3 that is located still 4, end cover 10 is located 6 one end of casing, cut straightly terminal 11 is located the 6 other ends of casing, support 7 is fixed in 6 inside near end cover 10 one side of casing, be fixed with ejector pin 8 on the support 7, 8 one end roof pressure of ejector pin video disc 9, other end roof pressure shell fragment 2.
