【考案の詳細な説明】 〔産業上の利用分野〕 本考案は電磁リレーに関し、特にコイル端子とヨークと
の電気的絶縁構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an electromagnetic relay, and more particularly to an electrical insulation structure between a coil terminal and a yoke.

An insulating thin plate 5b made of a polymer insulating material is arranged on the outer surface of the coil spool 1b, and an insulating resin 7b such as an epoxy resin is injected into a recess formed by the thin plate 5b and the cover 6b to cure the cover 6b. The structure is such that the opening is sealed.

たがって、これらコイル端子4bとヨーク2bとの絶縁縁面
距離が充分とれず、コイルとヨーク間の絶縁抵抗，耐電
圧が低いという欠点がある。However, in the above-described conventional electromagnetic relay, the coil terminal 4b is fixed to the end of the spool 1b in the vicinity of the yoke 2b in order to restrict the winding and reduce the size of the relay. Therefore, the insulation edge distance between the coil terminal 4b and the yoke 2b cannot be sufficiently secured, and the insulation resistance and withstand voltage between the coil and the yoke are low.

An insulating block interposed between the yoke and the coil terminal is provided, and an insulating resin that seals the opening of the cover is poured into a boundary surface between the insulating block, the spool, and the yoke, and the insulating block and the insulating block are provided. The feature is that it is integrated with the spool.

In the figure, an insulating block 3 made of a polymer insulating material is disposed between the coil terminal 4a and the L-shaped yoke 2a disposed in the groove of the spool 1a, and the yoke 2a
The insulating block 3 and the spool 1a are configured to be flush with each other, that is, to be flat. The contact common terminal 8 electrically connected to a movable contact (not shown) is fixed to the yoke 2a, so that the yoke 2a and the movable contact have the same potential. On the surface of the spool 1a, the yoke 2a, and the organic insulating block 3, an insulating thin plate 5a having an elliptical hole 7c at a position corresponding to the boundary surface between the yoke 2a, the spool 1a and the insulating block 3 is placed, and one end is opened. Insulating resin 7a is injected into the concave portion formed by the opening (upper side in the figure) of cover 6a. The insulating resin 7a flows into each boundary surface of the spool 1a, the yoke 2a, and the organic insulating block 3 through the elliptical hole 7c of the insulating thin plate 5a by a capillary phenomenon, and in the vicinity of the coil terminal 4a, the spool 1a, the insulating block 3, the insulating thin plate 5a, and The insulating resin 7a has an integrated structure made of each insulating material.

れる。As described above, according to the present invention, the coil terminal and the vicinity of the coil are integrated with each other by an insulating structure, so that the outer edge distance between the coil terminal and the yoke can be increased with the same external dimensions as the conventional electromagnetic relay. Therefore, it is possible to obtain an electromagnetic relay that realizes high insulation and high breakdown voltage between contacts and coils.
