Problems solved by technology

[0003] The existing high-load PCB automotive relays, on the one hand, have relatively large volume and lead-out pins, which require a large installation space due to their large size, and lead to poor solderability due to relatively large lead-out pins. On the other hand, the magnetic circuit part is fixed on the base through the positioning feet set on the yoke, and the positioning is not ideal

Abstract

The invention discloses a minitype heavy-current PCB (Printed Circuit Board) automobile relay, which comprises a base part, a magnetic circuit part, a movable spring armature part and a housing, wherein the base part comprises a base and a stationary spring fixed on the base, and the stationary spring is provided with stationary spring leading-out pins; the magnetic circuit part comprises a coil part and a yoke fixed to the coil part; the moving spring armature part comprises a movable spring and an armature fixed to the movable spring; the movable spring armature part is fixed to the yoke through the movable spring, so that the armature is arranged at a position corresponding and fit to the coil part; the yoke of the magnetic circuit part is provided with yoke leading-out pins extending integrally from the yoke to lead out an electrical signal of the movable spring; the magnetic circuit part is fixed to the base through the yoke; and the yoke is also provided with a positioning and fixing structure so that the magnetic circuit part is positioned in the transverse direction and longitudinal direction of the base. with the structure, the automobile relay has the characteristics that the size is small, the load capacity is large, the leading-out pins are good in weldability, the structure is simple, the magnetic circuit part is positioned accurately on the base, and the assembly process is good.

Description

technical field [0001] The invention relates to an automobile relay, in particular to a small-sized high-current PCB automobile relay with high load capacity, good weldability and good positioning. Background technique [0002] Automotive relays are electromagnetic relays used in the field of automotive automatic control. With the continuous improvement of automobile requirements for driving comfort and entertainment, the demand for on-board electronic equipment in a limited space is increasing, so the technical requirements for automotive relays are also getting higher and higher. Miniaturization and high load capacity are the requirements of automotive relays. development trend. [0003] The existing high-load PCB automotive relays, on the one hand, have relatively large volume and lead-out pins, which require a large installation space due to their large size, and lead to poor solderability due to relatively large lead-out pins. On the other hand, the magnetic circuit p...
