Relay

Abstract

The invention relates to a relay comprising a base (1), a skeleton (2), a coil, a yoke (3), an armature (4), a push rod (5), a movable reed (6), a movable spring lead-out slice (7), a static reed (8), a clamp spring (9), pins (10), an iron core and a housing, wherein the skeleton (2), the yoke (3), the movable reed (6) and the static reed (8) are all fixed on the base (1), the pins (10) are inserted on the skeleton (2), the coil is wound on the skeleton (2), the iron core is inserted to the skeleton (2), one end of the iron core is fixedly connected with the yoke (3), one end of the armature (4) passes through a gap on the tail end of the yoke (3), the other end of the armature (4) is placed at the upper part of the yoke (3) after being connected with the push rod (5), the movable spring lead-out slice (7) is fixedly connected with the movable reed (6) and abuts against the upper end of the push rod (5), one end of the clamp spring (9) abuts against the base (1), the other end of the clamp spring (9) passes through a through hole on the armature (4) and extends between the yoke (3) and the armature (4), and a first bulge (11) is arranged on the part of the base (1) extending between the push rod (5) and the yoke (3). As the bulge is arranged on the part of the base extending between the push rod and the armature, the creep distance between the movable reed and the yoke is increased, so that pressure resistance is enlarged, and then the safety of the relay is improved.

Description

technical field [0001] The invention relates to a relay. Background technique [0002] An existing relay comprises a base, a skeleton, a coil, a yoke, an armature, a push rod, a moving reed, a moving spring lead-out piece, a static reed, a retaining spring, pins, an iron core and a shell, a skeleton, a yoke, a moving Both the reed and the static reed are fixed on the base, the pins are inserted on the skeleton, the coil is wound on the skeleton, the iron core is inserted into the skeleton, one end of the iron core is fixedly connected with the yoke, and one end of the armature passes through the end of the yoke. The gap, the other end is fixedly connected with the push rod and placed above the yoke, the moving spring lead-out piece is fixedly connected with the moving reed and is against the push rod, one end of the circlip is against the base, and the other end extends through the through hole on the armature. between the yoke and the armature. This kind of relay has the ...

AI Technical Summary

Problems solved by technology

This kind of relay has the following problems: 1. The creepage distance between the moving reed and the yoke is short, the withstand voltage is small, and the safety is slightly insufficient; 2. The cross-section of the connecting part inserted into the frame on the pin is outside The shape of an isosceles trapezoid whose length is less than the length of the inner side. Since the slot on the skeleton is in the shape of a square hole and the diameter of the square hole is slightly larger than the length of the inner side of the connecting part, after the connecting part of the pin is inserted into the slot, there is still The large gap makes the pins easy to shake after insertion; 3. The armature and the push rod are usually connected by two methods, one is the integral injection molding method, but the efficiency of the integral injection molding is low, and the injection mold is easily damaged and the cost is high ; The other is the hot riveting method, but the hot riveting process is not mature, and the structure of the armature and the push rod connected by the hot riveting method is unstable
