Abstract

The invention relates to a small sealing release delay relay with long delay time. A programmable unijunction transistor V5 is taken as a potential comparison and drive element, a contact of a sealing magnetic latching relay J is taken as an output switching contact, and a three-layer structure design is adopted. The size is small, the environmental adaptation performance is good, the reliability is high, the delay time is up to 1200s, and the leakage rate is less than or equal to 1*10<-1>Pa.cm<3> / s.

Description

technical field [0001] The invention belongs to the technical field of relay manufacturing, and in particular relates to a small sealed release delay relay with long delay time. Background technique [0002] The release delay relay means that the relay pulls in after the input terminal is powered on (the normally open contact is connected and the normally closed contact is disconnected), and after the input power is cut off, the relay is released after a specified delay time (the normally open contact open, normally closed contact on). The difficulty is that after the input end is powered off, the relay relies on the electric energy of the internal energy storage element to provide the working electric energy of the delay circuit, and maintain and switch the state of the relay contacts. Due to the limited volume of the existing small sealed release delay relay, the energy provided by the internal energy storage element (generally an energy storage capacitor) is limited, and...
