Self-locking relay and application method thereof

Abstract

The invention discloses a self-locking relay and an application method thereof. The self-locking relay is characterized in that a shell of the self-locking relay is internally provided with an armature, an ejector rod locking sleeve, an ejector rod and a coil, the coil is horizontally installed at the inner bottom end of the shell, two coil pins of the coil respectively penetrate through the bottom surface of the shell, two pins are symmetrically welded on the bottom surface of the shell, the two pins respectively run through the lower bottom surface of the shell and extend to two sides of the ejector rod locking sleeve, an armature abnormal movement prevention spring is installed between one end of the armature and a cover body, the other end is connected with an armature ejector rod, one end, which is provided with tapered teeth, of the armature ejector rod is connected with the armature, the other end is inserted into an opening at one end of the ejector rod locking sleeve, and the other end of the ejector rod locking sleeve is sequentially provided with a shallow groove and a deep groove from the outside in. The self-locking relay does not need to be energized all the time, and the self-locking relay can be controlled to be self-locked or unlocked by only energizing a sucking coil once for a short time, thereby realizing connection or disconnection of a circuit, and always keeping a self-locking or unlocking state until the next time of energization.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a self-locking relay and a use method thereof. Background technique [0002] At present, the annual output value of the world's relays reaches 3.9 billion yuan, and the annual sales scale has exceeded 3.3 billion US dollars. In 2000, the output can reach 4.3 billion pieces, and the annual sales scale can reach 3.6 billion US dollars. Among them, the total output of relays in Japan accounts for about 1 / 3 of the world's total output, and the output value of relays in the United States is the highest, accounting for about 1 / 4 of the world's total output value of relays. In recent years, the proportion of the United States and Japan's relay output value in the world's total output value has declined, while Germany's share has risen from 17.47% in 1989 to 25% in recent years. Europe is the largest import and export market for relays. In 1993, the relay market in Western Europe accou...

Problems solved by technology

The disadvantage of the existing relay is that the coil must be energized all the time to make the relay work, resulting in the disadvantages of high power consumption and short service life of the coil due to long-term energization of the coil
