Abstract

The utility model discloses a relay, which comprises a restoring spring piece (1), an armature (2), a skeleton (3), a coil rack (4) and yoke iron, wherein an elastic tongue piece (1.1) is arranged on the middle part of the restoring spring piece (1), and two inwards-bent pins are arranged at the bottom of the restoring spring piece (1); the tongue piece (1.1) is inwards bent for extension; a groove (2.1) is formed in the bottom of the armature (2), and the end part of the tongue piece (1.1) is embedded into and attached to the groove (2.1). According to the relay, the armature can be well limited leftwards and rightwards in a swinging process, so that the armature is prevented from leftwards and rightwards swinging relative to the end part of the tongue piece of the restoring spring piece, and the suction force of the armature is ensured.

Description

Relay

Technical field

The utility model relates to electronic control device, specifically a kind of relay.

Background technology

When relay work, as long as add certain voltage at coil two ends, in coil, will flow through certain electric current, thereby produce galvanomagnetic effect, armature promotes moving spring by push rod, until moving spring and quiet spring adhesive.When after coil blackout, the suction of electromagnetism also disappears thereupon, and armature returns to original position, and moving spring separates with quiet spring.

There is at present a kind of relay, comprise yoke, armature, bobbin, reset reed, reset reed is provided with flexible tongue piece, the certain length of the end tongue of reset reed is bent at an angle downwards, the inclined-plane that the end tongue of reset reed forms after bending flexibly coincide and overlays the bottom at the first side surface of the armature of home position, the second side surface of the armature of home position and the base of yoke are close together, the contact position of position higher than the end tongue of reset reed and the first side surface of armature that contact on the second side surface of armature and the base of yoke.

Although the relay of this structure can guarantee to remain with yoke in armature swing process the basis of good contact above, but in the time that reality is used, still there is following shortcoming: due to the multiple angles that is provided with of relay, armature has endways, falling, sidewards, longitudinally all likely, causing like this armature in swing process, left and right is spacing not good, cause the end tongue of the relative reset reed of armature to swing, thereby affect the suction-combining force of armature.

Utility model content

The technical problems to be solved in the utility model is, provides a kind of armature in swing process, and the spacing property in left and right is good, avoids the end tongue of the relative reset reed of armature to swing, and guarantees the relay of the suction-combining force of armature.

The technical solution of the utility model is, a kind of relay with following structure is provided, comprises reset reed, armature, skeleton, bobbin and yoke, the middle part of described reset reed is provided with flexible tongue piece, bottom is provided with the pin of two bendings to the inside, and the bending to the inside of described tongue piece is extended; The bottom of described armature is provided with the groove that embeds and be affixed for end tongue.

The lateral surface of the bottom of the bottom surface of described groove and the tongue piece of reset reed fits.

The top of described reset reed is provided with two bending sections of bending to the inside.

Adopt after above structure, the utility model compared with prior art, have the following advantages: because the bottom of described armature is provided with the groove that embeds and be affixed for end tongue, make like this tongue piece can play the effect of spacing armature, avoid the end tongue of the relative reset reed of armature to swing, guarantee the suction-combining force of armature.

As improvement, the top of described reset reed is provided with two bending sections of bending to the inside, in the time occurring that skeleton does not withstand armature, can make the bending section of reset reed can withstand armature, dwindles gap, increases the suction-combining force of armature.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

As shown in Fig. 1～6, relay of the present utility model, comprises reset reed 1, armature 2, skeleton 3, bobbin 4 and yoke, and the middle part of described reset reed 1 is provided with flexible tongue piece 1.1, bottom is provided with the pin of two bendings to the inside, and the bending to the inside of described tongue piece 1.1 is extended; Between the both sides of tongue piece 1.1 and adjacent pin, be equipped with gap; The bottom of described armature 2 is provided with the groove 2.1 that embeds and be affixed for tongue piece 1.1 ends.

The lateral surface of the bottom of the tongue piece 1.1 of the bottom surface of described groove 2.1 and reset reed 1 fits, and the bottom surface of groove 2.1 is inclined-plane, and its angle of inclination is consistent with the angle of inclination of the tongue piece 1.1 after laminating, thereby guarantees that both fit.

The top of described reset reed 1 is provided with two bending sections 1.2 of bending to the inside, between described two bending sections 1.2, is provided with breach, and the bending part of each bending section 1.2 is arc transition.
