Description
Technical Field
The invention discloses a covering process of insulating glue of an overcurrent and overheat electrical protector, and belongs to the technical field of processing of protectors.
Background
Because the wiring terminal of the overcurrent and overheat electric protector is connected with the metal bottom plate in a sealing mode through the glass ring, the ring diameter of the glass ring is not too large, otherwise too many pores and bubbles in the glass affect the sealing performance and the air tightness of the whole protector. And the glass ring with the small ring diameter can cause the problem of insufficient air creepage distance between the wiring terminal and the bottom plate. The solution is to cover a layer of epoxy resin on the bottom plate, around the binding post and on the surface of the glass ring of the built-in overcurrent and overheat protector, so as to solve the problem of insufficient air creepage distance.
The existing process solution is as follows: the liquid material with bisphenol A-epichlorohydrin as main component is painted onto the base plate, wiring terminal and glass ring surface of the built-in overcurrent and overheat protector and solidified through long time or high temperature.
The above disadvantages are:
1. the scale production is very troublesome: before use, the curing agent with corresponding proportion is calculated and weighed, and then stirred and blended; people, machines and materials are easily polluted in the using process; the residual raw materials used at one time, even the raw materials in the using process can be automatically solidified, and the like, so that the method is not easy to use in batches and produce in a large scale.
2. Poor temperature resistance: the solidified epoxy resin is adhered to and covers the product, the use working condition of the built-in over-current and over-heat protector of the product is generally high temperature and high current, the environmental temperature is kept between 100 ℃ and 200 ℃, and the temperature of the metal parts of the built-in over-current and over-heat protector can be instantly raised to be more than 300 ℃ due to current impact. The epoxy resin is easy to be carbonized and decomposed when working at the temperature for a long time. After falling off, the carbonized and decomposed solid epoxy resin particles are easily filled between a rotor and a stator gap of the motor, so that the motor cannot run and is damaged or even burnt.
