Electromagnetic relay
An electromagnetic relay including a housing, a cover, an adhesive which is interposed between a side part of the housing and an inner surface of the cover and which secures the housing and the cover, and a projection which is formed in at least one of the side part and the inner surface. The adhesive is filled in a gap between the side part and the inner surface.
1. An electromagnetic relay, comprising:
a housing which includes an outer side part, the outer side part having a plurality of outer side part edges;
a cover which covers the housing, and includes an inner surface which faces the outer side part when the cover is covering the housing, the inner surface having a plurality of inner surface edges;
a projection which is formed on at least one of the outer side part and the inner surface and contacts with the other one of the outer side part and the inner surface when the cover is covering the housing; and
an adhesive which is interposed and filled in a gap between the outer side part and the inner surface while the projection contacts with the other one of the outer side part and the inner surface,
wherein the projection contacts with the other one of the outer side part and the inner surface to secure the gap between the outer side part and the inner surface, and wherein the projection is away from all of the plurality of outer side part edges when the projection contacts the outer side part or away from all of the plurality of inner surface edges when the projection contacts the inner surface.
2. The electromagnetic relay according to claim 1 , wherein:
a plurality of projections are formed on at least one of the outer side part and the inner surface, and each of the projections contacts with the other of the outer side surface and the inner surface.
3. The electromagnetic relay according to claim 2 , wherein:
the outer side part and the inner surface do not contact each other in a space between the projections.
