Description

A high-stability coupler Technical Field

[0001] This utility model belongs to the field of temperature controllers, specifically a high-stability coupler. Background Technology

[0002] Currently, the heating method of electric kettles commonly involves the thermostat installed in the kettle contacting the chassis with an electric coupler to transfer electrical energy. Electric kettles mainly consist of a base and a kettle body mounted on the base. In order to electrically connect the heating element and sensing element in the kettle body to the controller in the base, a lower coupler is installed on the base, and an upper coupler electrically coupled to the lower coupler is installed at the bottom of the kettle body. The conductor of the upper coupler consists of several concentric copper rings of different diameters, while the lower coupler is equipped with a contact spring. The contact touches the side or top of the copper ring, thereby realizing the flow of electricity during electrical coupling.

[0003] Most existing couplers use straight insert-type contacts to achieve electrical conduction of the temperature controller. After the contacts are installed, they are in close contact with the copper ring. Over time, poor contact with the copper ring can easily occur, resulting in poor stability of the coupler.

Each electrical plate includes a blocking part, and the blocking part includes an end. The end is V-shaped. The annular protrusion has a groove, and the blocking part passes through and is inserted into the groove. One side of the blocking part abuts against the annular protrusion. The ends of the end are provided with abutting parts for abutting against the two sides of the annular protrusion.

The cover plate is provided with a concave surface on the side away from the annular convex shroud.

[0009] Preferably, each of the copper rings is provided with a bent foot, and the bent foot abuts against the concave surface.

[0010] Preferably, the base has multiple positioning posts on the side away from the base.
