Abstract

A coil terminal has a winding section comprising an end of coiled wire wound therearound. The winding section is bent relative to a remaining section of the coil terminal. The winding section has a proximal wire engagement portion and a distal wire engagement portion spaced away from each other in a longitudinal direction of the winding section, and an intermediate region disposed between the proximal wire engagement portion and the distal wire engagement portion. The wire end is extended in the intermediate region without being wound around the intermediate region.

First claim

What is claimed is:

1. An electromagnetic relay comprising:
a coiled wire having opposite ends; and
a pair of coil terminals having respective winding sections connected with the opposite wire ends;
wherein the winding sections are bent relative to remaining sections of the coil terminals so that an insulation distance between the coil terminals is maintained constant before and after bending the winding sections;
wherein each of the winding sections comprises a proximal wire engagement portion and a distal wire engagement portion spaced away from each other in a longitudinal direction of the winding section, and an intermediate region disposed between the proximal wire engagement portion and the distal wire engagement portion, and
wherein each of the wire ends is extended in the intermediate region without being wound around the intermediate region.

2. The electromagnetic relay of claim 1 , wherein a part of the wire end is wound around and then soldered to a distal region of the distal wire engagement portion.

3. The electromagnetic relay of claim 1 , wherein each of the proximal and distal wire engagement portions has a convex configuration.

4. The electromagnetic relay of claim 1 , wherein one of the proximal and distal wire engagement portions has a convex configuration and the other of the proximal and distal wire engagement portions has a concave configuration.

5. The electromagnetic relay of claim 1 , wherein each of the proximal and distal wire engagement portions has a concave configuration.

6. The electromagnetic relay of claim 1 , wherein the proximal and distal wire engagement portions are angularly offset from each other about a longitudinal axis of the winding section.

7. The electromagnetic relay of claim 1 , wherein the proximal and distal wire engagement portions are positioned on opposite sides of a longitudinal axis of the winding section.

8. The electromagnetic relay of claim 2 , wherein each of the proximal and distal wire engagement portions has a convex configuration.

9. The electromagnetic relay of claim 2 , wherein one of the proximal and distal wire engagement portions has a convex configuration and the other of the proximal and distal wire engagement portions has a concave configuration.

10. The electromagnetic relay of claim 2 , wherein each of the proximal and distal wire engagement portions has a concave configuration.

11. The electromagnetic relay of claim 2 , wherein the proximal and distal wire engagement portions are angularly offset from each other about a longitudinal axis of the winding section.

12. The electromagnetic relay of claim 2 , wherein the proximal and distal wire engagement portions are positioned on opposite sides of a longitudinal axis of the winding section.
