Description

Automobile relay

Technical Field

The invention belongs to the technical field of relays, and particularly relates to an automobile relay.

At present, automobiles become important tools for people to ride instead of walk, and small relays in the automobiles are mainly used in occasions with large starting current, such as automobile fuel pumps, headlights, horns, A/C compression clutches and the like; in order to adapt to the progress and development of the modern society, the production of the small automobile relay has become a large-scale and automatic production mode, and how to improve the cost control and saving in the production of the small automobile relay becomes a way for improving the profit of enterprises. In production, the assembly process of the small automobile relay comprises the following steps:

firstly, the movable spring piece and the movable spring leading-out piece are welded, and the movable spring piece is not easy to misplace due to positioning during welding, so that the problems of low production efficiency and high defective rate are solved;

secondly, the iron core is usually processed into a flat cylinder, and the condition that the action is delayed or even the on-off of the relay cannot be realized due to insufficient magnetic attraction can occur when the flat cylinder iron core is used for a long time, so that the service life of a product is shortened;

thirdly, the static reed and the static contact are assembled in the process of drilling a round hole in the static reed and riveting the static contact and the static reed together; when the small automobile relay formed by directly riveting the static reed and the static contact is used, the riveted part is separated due to insufficient strength, so that the service life of a product is shortened;

fourthly, the lead pins are arranged on the base to be connected, and then the resistors are abutted against the lead pins and are welded and fixed with the lead pins. When the small automobile relay assembled by welding the resistor on the lead pin is used, the resistor welded on the lead pin is easy to separate from the lead pin, thereby reducing the service life of the product; in addition, in this process, a material such as solder is required for the welding process, which requires high cost.
