Abstract

The invention relates to an electromagnetic relay for an automobile. The relay comprises a base, an H-shaped coil frame with a coil, electronic elements, lead wire sheets, plug pins, an armature and yoke iron, wherein the H-shaped coil frame is installed on the base and made of composite resin, the bottom ends of the two sides of the H-shaped coil frame are provided with notches for the lead wire sheets to be inserted in, the electronic elements are integrated on a circuit board which is arranged on the base, metal sheets are connected between the circuit board and the lead wire sheets, the yoke iron and the armature are connected in an inserted mode and inserted in the base, one side face of the yoke iron is attached to one side wall of the H-shaped coil frame, the armature is attached to the other side wall of the H-shaped coil frame, a movable reed is attached to the surface of the armature, a movable contact is arranged at the front end of the movable reed, and static reeds with static contacts are arranged on the two sides of the movable reed and correspond to the movable contact. According to the electromagnetic relay, the electronic elements are integrated on one circuit board, bridging is performed between the circuit board and the coil through the metal sheets, the problem that the electronic elements occupy space is solved, and the space utilization rate of the relay is increased.

Description

Technical field: [0001] The invention belongs to the electrical field and relates to a relay, in particular to an electromagnetic relay for automobiles. Background technique: [0002] Coils in automotive relays are generally connected with electronic components such as resistors, capacitors, and diodes, and spot welding is generally used to connect electronic components and coils, and spot welding is likely to cause virtual welding, and multiple electronic components are welded together. Space utilization needs to be considered, so welding needs to be very careful and careful, and the welding method has certain risks and is time-consuming, and the production efficiency is not high. Therefore, in order to improve the quality of the relay, it is necessary to invent a method that can replace the relay welding technology to improve Productivity. [0003] In addition, the material of the coil frame in the automotive relay is generally relatively strict. Considering all aspects, ...
