Fixing-clamping electrically-connected waterproof temperature controller

Abstract

The invention relates to the technical field of temperature controllers, in particular to a fixing-clamping electrically-connected waterproof temperature controller. The fixing-clamping electrically-connected waterproof temperature controller comprises a waterproof shell, and a temperature sensing action mechanism is arranged in the waterproof; two power connecting terminals are arranged on the upper end face of a fixedly-arranged base, wire clamping openings are formed in the upper ends of the power connecting terminals, and wire grooves are formed in the inner side faces of the power connecting terminals; in-and-out lead wires are arranged on the side wall of the waterproof shell in a penetrating mode, the power connecting ends of the lead wires penetrate through the wire clamping openings to be bent to be in an L shape, are embedded into the wire grooves, and are electrically connected with the power connecting terminals, and wire fixing pressing blocks are arranged on the power connecting terminals, arranged at the power connecting ends of the lead wires in a sleeving mode and connected with the power connecting terminals in a matched mode. The fixing-clamping electrically-connected waterproof temperature controller is reasonable in structural arrangement, the lead wires penetrate through the wire clamping openings to be bent and are embedded into the wire grooves and wire buckling grooves, a back pressing plate is clamped to insulating layers of the lead wires through positioning clamping openings, the lead wires are fixed in a multidimensional mode from the two sides of the power connecting terminals through the wire fixing pressing blocks, the electrical-connection stability between the lead wires and the power connecting terminals is improved, automatic assembling can be achieved, and production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of thermostats, in particular to a waterproof thermostat with fixed card electrical connection. Background technique [0002] The reset type thermostat is a common temperature control overheating protector on household appliances at present. It has the functions of self-acting protection, permanent disconnection without power failure, and self-reset function after power failure. Household appliances are generally equipped with reset-type thermostats with power-off protection to protect household appliances from damage caused by excessive operating temperature or dry burning. After the temperature control overheating protector is powered on, if the set temperature exceeds the set temperature when dry burning occurs, the metal sheet inside the thermostat deforms and moves, thereby pushing the moving contact on the shrapnel of the action lever away from the static contact. [0003] The working environment of h...

AI Technical Summary

Problems solved by technology

However, neither of the above two waterproof thermostats can solve the reliability problem of the electrical connection between the lead wire and the electrical terminal. The lead end and the electric terminal are welded. In order to facilitate the assembly of the lead end and the connecting part of the electric terminal, the height of the connecting part is consistent with the clamping opening of the shell. Problems such as increased contact resistance, inconsistent temperature rise, etc.
