Abstract

A non-epoxy sealed mini temperature controller relates to the field of electric components. The controller comprises a casing, the casing is internally provided with a metal substrate, the metal substrate is provided with a pedestal and a static contact, the pedestal is provided with a contact sheet, a spring leaf and a bimetallic strip are arranged in the casing over the pedestal, one end of spring leaf and one end of the bimetallic strip are welded to the contact sheet, the middle portion of the spring leaf and the middle portion of the bimetallic strip are supported by the pedestal, the other end of the spring sheet is provided with a movable contact cooperated with the static contact, an open end of the casing is internally provided with two pins, one pin is electrically connected with the metal substrate, the other pin is electrically connected with the bimetallic strip, a plastic block is embedded into the open end of the casing, and the two pins penetrate the plastic block and extend out of the casing. The plastic block is used to replace epoxy resin embedding technology to overcome the disadvantages that epoxy resin is high in irritability, long in solidification time and high in material cost, the cost is saved, and the market efficiency is improved.

Description

Technical field [0001] The invention relates to the field of electrical components, in particular to an epoxy-free sealed miniature temperature controller. Background technique [0002] Similar products on the market all use epoxy resin potting to achieve the effect of fixing and sealing, but epoxy resin has strong allergy, long curing time and high material cost. This virtually increases manufacturing difficulty and cost. Moreover, this method cannot guarantee the uniformity of the protector pin spacing, and will contaminate the pins, making it unsuitable for PCB board jack installation. Summary of the invention [0003] The purpose of the present invention is to provide an epoxy-free sealed miniature temperature controller with a simple structure and adjustable pin spacing. [0004] The technical solution to achieve the above objective is: epoxy-free sealed miniature temperature controller, including a shell with one end open, a metal bottom plate is arranged in the shell, a bas...
