A ferrule electrically connected to a thermostat

Abstract

The invention relates to the technical field of thermostats, in particular to a hoop sleeve electrically connected thermostat. It includes a waterproof case, a temperature-sensing mechanism and lead wires. The upper end of the waterproof case is provided with an opening, the temperature-sensing mechanism is fixed in the lower inner cavity of the waterproof case, and the lead wires are threaded on the side wall of the waterproof case; The temperature-sensing mechanism includes a fixed base, the upper end surface of the fixed base is provided with two electrical terminals respectively electrically connected with the lead wires in and out; the fixed base is provided with a hoop mechanism for fixing the lead wires in and out. The invention has a reasonable structure, the lead wire is fixed on the height-fixing base through a band, and the core head of the lead wire passes through the clamping groove and then is bent to be electrically connected with the electric terminal, so as to avoid the deformation and damage of the electric connection part caused by the influence of the external force on the lead wire. The problem of poor contact; the lead wires pass through the height-fixing base and the clamping groove sequentially along the same height, and the band wraps around the insulating layer of the lead wires and fixes them on the fixed base, which can realize automatic assembly and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of thermostats, in particular to a hoop sleeve electrically connected thermostat. 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 household appli...

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.
