Abstract

The invention relates to a snap-action temperature controller which comprises a shell body, a bimetallic strip, a contact pair and a drive device, wherein, the contact pair includes a static contact and a moving contact; the snap-action temperature controller is characterized in that the moving contact is electrically connected with a connecting terminal by a conducting strip; the conducting strip comprises a first reed and a second reed which are laminated together; when the drive device causes the contacts to be disconnected under the action of the flexural deformation of the bimetallic strip, the second reed directly leans against the drive device, in addition, the thickness of the second reed is between 0.1mm and 0.8mm while the proportion of the thickness of the first reed to the thickness of the second reed is between 1:4 to 1:1. Compared with the prior art, the temperature controller changes the conducting strip connecting the moving contact with the connecting terminal into a structure with two reeds laminated together; the double-reed structure increases the area of electrified section of the conducting strip, thereby improving the load bearing capability of the conducting strip, causing the temperature controller to be capable of bearing current as high as 50A and ensuring that the temperature controller can be connected with large-power load.

Description

technical field [0001] The invention relates to a temperature controller, in particular to a jump type temperature controller which adopts a disc-shaped element made of a bimetal sheet as a temperature sensing element. Background technique [0002] Usually, the temperature controller is provided with a contact pair that can control the conduction or disconnection of the external electric heating circuit, and the contact pair includes a moving contact and a static contact. Generally, the moving contact is electrically connected through the conductive sheet and the terminal connected in series in the electric heating circuit. In the initial state, if the external electric heating circuit is conducting, the starting contact and the static contact are in contact. When the temperature rises and the bimetal jumps in the opposite direction, the bimetal will push the ceramic rod to open the moving contact. At this time, the moving contact and the static contact are separated, and th...
