Description

Technical Field

[0001] The utility model relates to the field of temperature controllers, in particular to a bimetallic strip for temperature controllers. Background Art

[0002] The bimetallic strip for the thermostat is small in size and is not provided with a positioning structure. Therefore, it is not easy to fix the two metal strips during actual installation, which makes the operation inconvenient. Moreover, after the fixation is completed, the metal strips may shift during actual use, and the fixation is not stable enough. Therefore, the utility model proposes a bimetallic strip for the thermostat to solve the above problems. Utility Model Content

[0003] In order to overcome the defects in the above-mentioned prior art, the utility model provides a bimetallic strip for a temperature controller. By setting protrusions and relative through holes, the two metal strips can be quickly positioned. At the same time, combined with the wrapping strip, not only can rapid fixation be achieved, but the connection between the metal strips can also be more stable and less likely to shift.

[0004] Technical Solution

[0005] A bimetallic sheet for a temperature controller comprises a heat-conducting aluminum sheet and a metal sheet. The heat-conducting aluminum sheet is punched with a convex point, the metal sheet is provided with a through hole adapted to the convex point, and the convex point is inserted into the through hole for positioning.

[0006] Furthermore, the heat-conducting aluminum sheet is penetrated by a first opening.

[0007] Furthermore, the metal sheet is penetrated by a second opening which is directly opposite to the first opening.

[0008] Furthermore, two symmetrically positioned wrapping sheets are connected to one end of the heat-conducting aluminum sheet away from the first opening.

[0009] Furthermore, the wrapping sheet is bent and wraps the metal sheet and fixes the heat-conducting aluminum sheet and the metal sheet.

[0010] Furthermore, a ceramic connection hole is provided on the metal sheet.

[0011] Beneficial Effects

[0012] Compared with the prior art, the utility model has the following beneficial effects: by setting the protrusions and the corresponding through holes, the two metal sheets can be positioned quickly and rapidly, and combined with the wrapping sheet, while achieving rapid fixation, the connection between the metal sheets can also be more stable and less likely to shift. At the same time, the eccentrically set protrusions and through holes can also prevent the thermal conductive aluminum sheet and the metal sheet from being installed reversely.
