Problems solved by technology

However, if the terminal is fixed to the base made of thermosetting resin by press-fitting, cracks or resin chips are likely to occur on the base.
Therefore, it is difficult to fix the terminal to the thermosetting resin base by pressing
However, if the terminals are not fixed to the base by press-fitting, the positions of the terminals cannot be determined stably, and the position of the assembled terminals may deviate.

Abstract

The invention provides an electromagnetic relay which has high heat resistance and can stably mount a terminal on a base. The susceptor is made of a thermosetting resin. The first terminal extends through the first hole. And the fixing part is independent from the base. The fixing member has elasticity higher than that of the thermosetting resin. The fixing member fixes the first terminal to the base. The fixing member includes a first support wall and a first recess. The first support wall is disposed between an inner surface of the first hole and the first terminal. The first support wall extends upward along the first terminal. The first recess is disposed on the upper surface of the first support wall and faces the first terminal. The first adhesive is filled in the first recess. The first adhesive adheres the first terminal and the first support wall.

Description

technical field [0001] The invention relates to an electromagnetic relay. Background technique [0002] An electromagnetic relay includes a base and terminals. The base is made of resin, and holes for inserting the terminals are provided in the base. As shown in Patent Document 1, the terminal is fixed to the base by press-fitting. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2016-110844 [0004] In a high-capacity electromagnetic relay, the base is preferably made of a thermosetting resin from the viewpoint of heat resistance. However, when the terminal is fixed to the base made of thermosetting resin by press-fitting, cracks or resin chips are likely to occur on the base. Therefore, it is difficult to fix the terminal to the thermosetting resin base by press fitting. However, unless the terminals are fixed to the base by press-fitting, the positions of the terminals cannot be determined stably, and the positions of the assembled terminals may deviate. C...
