Full-automatic high-intensity relay

Abstract

The invention provides a full-automatic high-intensity relay. An iron frame (2), yoke iron (3), a moving reed (6) and a static reed (8) are fixed on a pedestal (1). A pin (10) is inserted in the iron frame (2). A coil is wound on the iron frame (2). An iron core is inserted in the iron frame (2). One end of the iron core is fixedly connected with yoke iron (3). One end of an armature (4) penetrates through the notch of the tail end of yoke iron (3), and the other end of the armature (4) is connected with a push rod (5) and then placed above yoke iron (3). A moving spring lead-out sheet (7) is fixedly connected with the moving reed (6) and abutted against the upper end of the push rod (5). One end of a clamping spring (9) is abutted against the pedestal (1), and the other end penetrates through the through hole on the armature (4) and stretches into the position between yoke iron (3) and the armature (4). The part, which stretches into the position between the push rod (5) and yoke iron (3), of the pedestal (1) is provided with a first protrusion (11).

Description

technical field [0001] The invention relates to a fully automatic high-intensity relay. Background technique [0002] There is a fully automatic high-strength relay, which includes a base, an iron frame, 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 casing, and the iron The frame, yoke, moving reed and static reed are all fixed on the base, the pins are inserted on the iron frame, the coil is wound on the iron frame, the iron core is inserted in the iron frame, and one end of the iron core is fixedly connected with the yoke One end of the armature passes through the gap at the tail end of the yoke, 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 against the push rod, one end of the circlip is against the base, and the other end Pass through the through hole on 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 iron frame on the pin is The shape of an isosceles trapezoid whose outer side length is smaller than the inner side length. Since the slot on the iron frame is in the shape of a square hole and the diameter of the square hole is slightly larger than the inner side length of the connecting part, after the connecting part of the pin is inserted into the slot, the inside of the slot There is still a large gap, which makes the pin 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. 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
