Problems solved by technology

[0003] The problems existing in the existing overload temperature control protector are: the contact between the moving contact and the static contact under the moving contact is closely connected with electricity, and the connection between the moving contact and the static contact is not tight enough, which may cause ignition; When overloaded, rely on the thermal expansion of the bimetal to drive the moving contact away from the static contact. When the performance of the bimetal is weakened, there is no sufficient power to drive the moving contact away from the static contact, which is not safe enough; after the current overload occurs, the bimetal The temperature of the metal sheet drops and restores its shape to connect the circuit. This method has no time to check the overload principle and solve the overload problem.

Abstract

The invention belongs to the technical field of overload temperature control protectors, and particularly relates to an overload temperature control protector, which comprises a bearing plate, a leftshell and a right shell, the bearing plate is provided with a bulge, the top of the left end of the bearing plate is provided with an insulating base plate, and the top of the insulating base plate isfixedly connected with a static contact piece; and the inner wall of the static contact piece is connected with a movable contact in an inserted mode, baffles are arranged at the two ends of the static contact piece, a movable contact piece is integrally formed at the top of the movable contact, and an arc-shaped contact plate is integrally formed at the bottom of the movable contact piece. The invention has the beneficial effects that circuit opening does not only depend on deformation of a metal piece assembly, an elastic piece assembly is additionally arranged, when overload occurs, the movable contact piece is lifted upwards, the force of the movable contact separated from the static contact piece is enhanced, the safety is greatly improved, after the circuit is disconnected after overload occurs, the temperature of each component returns, the circuit cannot be automatically connected, sufficient time is reserved for overload troubleshooting and overload problem solving for people, and the clamping safety is improved.

Description

technical field [0001] The invention relates to the technical field of overload temperature control protectors, in particular to an overload temperature control protector. Background technique [0002] As a temperature-sensitive controller for automatic circuit control, the temperature-controlled protector is widely used in household appliances and industrial electricity and other fields. It is one of the safety accessories for circuit protection. Its working principle is to use it when the circuit is overloaded. When the current in the circuit increases sharply, if the circuit is not found and disconnected in time, it will burn out. By connecting the temperature control protector in series in the circuit, the temperature control protector is equipped with a high-sensitivity temperature sensitive When the temperature rises sharply, the bimetal sheet of the component will be deformed, so that the dynamic and static contact points will be separated, and then the circuit will b...
