Abstract

The invention provides a normally opened relay. The relay comprises an electromagnetic mechanism, a connecting base and a shell, wherein an input pin is formed by a pin and a connecting sheet; a resistor can be embedded in a notch outside the upper part of the pin; one edge of the L-shaped connecting sheet is riveted with the upper end of the pin; a horizontal needling on one side of the other edge of the connecting sheet is embedded into the upper edge of a frame, while a horizontal branch on the other side is welded with a leading-out wire; a heel piece and an output pin of a moving contact are connected into a whole, wherein the moving contact and an armature are respectively riveted with one side of an L-shaped reed, while the other side of the L-shaped reed is riveted with the heel piece. By virtue of improvement on the existing normally opened relay for a minicar, the problem of poor radiation performance of heavy load excessive current is solved, part design is simplified, the number of parts is reduced, and the assembly precision is improved.

Description

technical field [0001] The invention relates to electronic devices, in particular to a normally open relay. Background technique [0002] Miniature relays are widely used electronic devices in automobiles. In order to improve the versatility and interchangeability of relays and improve the reliability of vehicle electrical systems, the international standard (ISO-7588-3-1998) road vehicles - electrical / electronic The fifth part of switchgear: miniature relays, respectively regulates the external dimensions, pin position and functions of normally closed relays, normally open relays and changeover relays. However, with the rapid development of modern automobiles, higher requirements are put forward for automotive normally-open relays, such as large load (20A 12VDC), low driving power (1.1W), etc., resulting in new problems that are difficult to dissipate heat due to excessive current. The problem is that the internal space of the relay is very small, and the number of parts i...
