Problems solved by technology

Due to the particularity of the solenoid direct-acting magnetic circuit, there are roughly two structural designs of the auxiliary contact in the market. One is the "reed switch" structure of the American TE company, such as the auxiliary contact of the TE model EV500; The other is Gigavac's reed structure, but both of these two structures have the disadvantages of being unable to make "one set of conversions" and poor reliability

Abstract

The invention discloses a high-voltage direct-current relay with auxiliary contacts. The high-voltage direct-current relay is composed of a pushing mechanism, a main moving spring with double main moving contacts, two main leading-out terminals respectively provided with main fixed contacts, an auxiliary moving spring with dual auxiliary moving contacts, two first auxiliary leading-out terminals respectively provided with first auxiliary fixed contacts, and a yoke plate. The pushing mechanism penetrates and sleeves the yoke plate. The main moving spring is installed at the upper end of the pushing mechanism; the auxiliary moving spring is installed on the pushing mechanism between the main moving sprng and the yoke plate; the two first auxiliary leading-out terminals are fixed on the yokeplate by adaptive members with insulation structures to realize mutual insulation with the yoke plate; and the auxiliary moving contacts at the two ends of the auxiliary moving spring correspond to the first auxiliary fixed contacts of the two first auxiliary leading-out terminals on the yoke plate. According to the high-voltage direct-current relay disclosed by the invention, one group of converted auxiliary contact structures is realized, so that the reliability of the high-voltage direct-current relay is improved substantially.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a high-voltage direct-current relay with auxiliary contacts. Background technique [0002] In order to be able to monitor the state of the main circuit in practical applications, high-voltage DC relays often require additional small-signal load circuits to monitor, that is, auxiliary contacts are required. Due to the particularity of the solenoid direct-acting magnetic circuit, there are roughly two structural designs of the auxiliary contact in the market. One is the "reed switch" structure of the American TE company, such as the auxiliary contact of the TE model EV500; The other is Gigavac's reed structure, but both structures have the disadvantages of being unable to make "one set of conversions" and poor reliability. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a high-voltage DC relay wit...
