Abstract
The present invention relates to a low height small-sized large power multiple contacts AC-DC electromagnetic relay with a winding shaft pushing mechanism. At least one group of movable contact springs of a contact system are connected by insulating pieces to form movable contact spring rows. Both ends of the insulating piece are provided with rotating shafts. A corresponding rotating shaft hole is arranged on a pushing block to form hinge connection. The rotating shaft hole on the pushing block is clamped on an armature boss. When an armature moves, the transmission function of the pushing block drives the movable contact part of the relay to move. The use of a tension spring is avoided, so the present invention does not need hooks to reduce the height of the relay. A magnetic circuit and the contact part adopt high insulation design, and an electrical distance, a creepage distance and a penetration insulation distance are all higher than those of the original relay, which enhances the press resistance of a medium. The movable contact springs of a plurality of contact groups are connected by the insulating pieces to form the movable contact spring rows, movable contact lead-out springs are connected by insulating pieces to form movable contact lead-out spring rows, and the movable contact spring rows are connected with the movable contact lead-out spring rows by riveting press, so the adoption of flexible solder connection is avoided to reduce product cost.

The CN1405815A patent application provides a kind of and goes up vertical high isolation of mo(u)ld bottom half, little erection space structure, strength member adopts the variable cross-section design, structure is more compact, the load volume is higher, assembling is adjusted simpler, the more reliable high-isolated vertical miniaturized variable-section high-power electromagnetic relay of working, be provided with electromagnetic system, contact system, carrier part framework, contact part push card and shell, magnetic circuit system is by coil, yoke, armature, stage clip constitutes, contact system is by movable contact spring, the contact, lead-out tablet constitutes, an end that it is characterized in that said push card is provided with platform, be provided with groove and convex tendon in the bottom of platform, and with carrier part framework on corresponding convex tendon that is provided with and groove interlock.
Summary of the invention
The object of the present invention is to provide a kind of low clearance, simple in structure, the small-sized high-power of the band winding shaft pushing mechanism of assembling, good manufacturability is organized the AC and DC electromagnetic relay of contact more, can carry out the production of batch streamline, performance/volume ratio all is better than existing similar relay with the P/C ratio.
Another object of the present invention is to provide a kind of many groups contact AC and DC electromagnetic relay of high performance low clearance band winding shaft pushing mechanism, dielectric withstanding voltage is greater than 2500VAC between contact and coil, between contact sets, dielectric withstanding voltage is greater than 1000VAC between the contact, height can reduce 6mm, and its P/C ratio and performance/volume ratio all are better than existing like product.
The present invention includes magnetic circuit system, contact system, base portion, at least one group of movable contact spring of contact system is connected to form movable contact spring row by insulating part, is provided with rotating shaft at the two ends of insulating part.Be provided with corresponding shaft hole on pushing block, form hinge and connect, the shaft hole on the pushing block is installed on the armature boss, and by the pushing block transfer function, the moving contact that drives relay partly moves during armature motion.This movable contact spring row can be designed to a group or more many groups structure.
Said insulating part can adopt working of plastics.
Armature is provided with two and clamps boss, contacts by clamping the hole that clamps that cooperates with on the pushing block, and the Motion Transmission of armature is arrived the movable contact spring part.When armature motion, drive movable contact spring and partly move, drive the relay contact conversion.The front end of shaft hole is unidirectional opening, and the rear end is borehole structure, can conveniently snap in the rotating shaft at insulating part two ends.
The hole that clamps on the pushing block is designed to the hyperboloid structure, and the plane of two curved surface tops and armature boss joins, and the no interference rotation in the certain angle can be provided.
Magnetic circuit system comprises yoke, armature, short-circuited conducting sleeve, reset reed, coil etc.Yoke and armature are L-shaped, and pack into by the correcting projection and to position in the guide groove on the base, and by a glue magnetic circuits such as bobbin are partly fixedly secured in base portion.Reset reed design has two symmetric arms, and a hole is arranged on each arm, and two buds should be arranged on the armature mutually, with the reset reed riveting together.The design of the other end of reset reed clamps hangnail, is inserted in the seam that bobbin and yoke form, and owing to the hangnail effect, carries out spacingly, fixes the armature part.
Owing to avoid using extension spring, therefore do not need the design hook, reduced the height of relay.Magnetic circuit part adopts high isolation design with contact part, electrical distance, creepage distance, penetrates insulation apart from all than original similar relay height, thereby reaches the purpose that improves dielectric withstanding voltage.
Because the movable contact spring of many group contact sets adopts insulating part to be connected to form movable contact spring row, moving spring lead-out tablet also is connected to form moving spring lead-out tablet row by insulating part, and connects by riveting.Avoid adopting the soft wiring soldering of existing like product to connect, avoid the pollution in the soldering process, and effectively reduce product cost.
