Abstract

An electromagnetic relay including: a base unit that includes a slit having a first wall part and a second wall part, and a first projection projecting from the first wall part of the slit; a terminal that is press-fitted into the slit, and includes a second projection at a position opposite to the first projection; and a preventer that prevents deviation of the second projection against the first projection when the terminal is press-fitted into the slit.

First claim

What is claimed is:

1. An electromagnetic relay comprising:
a base unit that includes a top, a bottom and a side between the top and the bottom, a slit defined by a first wall part and a second wall part to open to the top and the side of the base unit, and a first projection projecting from the first wall part outwardly toward the second wall part;
a terminal that is press-fitted into the slit in a first, press-fitting direction into the side of the base unit parallel to the bottom of the base unit, and includes a second projection at a position opposite to the first projection and projecting outwardly toward the first wall part; and
a preventer formed on one of the first and second projections that extends in the first press-fitted direction, and prevents the terminal from moving in a second direction perpendicular to the first direction.

2. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is a concave part that is formed on the first projection and receives the second projection.

3. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is protruding parts that are formed on the first projection and sandwich the second projection.

4. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is third projections that are adjacent to the first projection and formed on the first wall part, each of the third projections being higher than the first projection.

5. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is a concave part that is formed on the second projection and receives the first projection.

6. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is a fourth projection that projects from the second wall part so as to be opposite to the first projection, and
the fourth projection engages with a concave part formed on the back of the second projection when the terminal is press-fitted into the slit.

7. The electromagnetic relay as claimed in claim 1 , wherein
the preventer is a fifth projection arranged on the first wall part so that a distance from a bottom surface of the slit is identical with a thickness of a part of the terminal, and
the part of the terminal is sandwiched between the bottom surface of the slit and the fifth projection when the terminal is press-fitted into the slit.

8. The electromagnetic relay as claimed in claim 1 , wherein
at least one of the first projection and the second projection includes a stopper for stopping the movement of the terminal in a press-fitting direction where the terminal is press-fitted into the slit.

9. The electromagnetic relay as claimed in claim 1 , wherein the preventer comprises a linear groove extending in the first direction defined by two spaced linear projections extending in the first direction.
