Problems solved by technology

On the other hand, with the miniaturization of electromagnetic relays, the reduction of contact driving performance due to the reduction of the volume of the coil in the electromagnetic relay, the reduction of the conduction performance due to the increase of the resistance of the conduction path in the electromagnetic relay, and the reduction of the distance between terminals occur. The problems caused by the decline of insulation properties, etc., so further improvement of these properties is required

Abstract

The issue is to provide a small electromagnetic relay with superior conduction characteristics that has high insulating capacity between two fixed contact terminals and between the fixed contact terminals and the backstop, and, by having few malfunction-generating factors, exhibits highly reliable contact between contacts. The electromagnetic relay is configured with an electromagnet block provided with a movable contact spring (14) that rocks by means of current flowing to a coil, two fixed contact terminals (22) and (22') that have fixed contacts, a backstop (23) that has two movable contact touch parts, and a base block (2) that holds thecomponents. The base block (2) has fixed contact terminal holding parts (21) and (21'), the base part (20) of which has a rectangular shape, and that hold the fixed contact terminals at two opposing sides of the rectangular shape, and a backstop holding part (24) that holds the backstop (23) in the middle of one side between the two sides.

Description

technical field [0001] The present invention relates to an electromagnetic relay mounted on a printed wiring board or the like as an electrical component of an automobile or the like. Background technique [0002] Along with the increase in the electrical installation rate of automobiles, the miniaturization and high-density mounting of the installed electrical installation devices are also progressing, and the electromagnetic relays mounted on such electrical installation devices are also required to be miniaturized. On the other hand, with the miniaturization of electromagnetic relays, the reduction of contact drive performance due to the reduction of the coil volume in the electromagnetic relay, the reduction of the conduction performance due to the increase of the resistance of the conduction path in the electromagnetic relay, and the reduction of the distance between terminals occur. There are problems such as a decrease in insulation performance, and further improvemen...
