Abstract

Provided is a terminal of a relay constituted by an assembly of a plurality of members, with which plastic deformation can be prevented, and a relay including the terminal. A movable terminal of the relay is constituted by an assembly of a first member having two legs, and a second member having a contact, wherein the second member has at least three holes, the first member has at least three protrusions which are individually inserted into and crimped in the at least three holes, and an intermediate hole among the at least three holes is arranged so as to be positioned on the side opposite the contact with respect to a straight line that contacts the edges of the outermost holes on the side close to the contact.

First claim

The invention claimed is:

1. A terminal, comprising:
a first member having a leg; and
a second member combined with the first member and having a contact, wherein the second member has at least three holes, the at least three holes including a middle hole and outer holes located on both sides of the middle hole, respectively,
wherein the first member has at least three protrusions which are individually inserted into and crimped in the at least three holes, and
wherein each of the middle hole and the outer holes has an edge closer to the contact, and the edge of the middle hole is arranged so as to be positioned farther from the contact point than a straight line that contacts the edges of the outer holes.

2. The terminal according to claim 1 ,
wherein the first member comprises a support part on which the at least three protrusions are formed, and
wherein the support part supports the second member on a first side on which the contact is provided.

3. The terminal according to claim 1 , wherein the leg comprises a proximal end which protrudes from the second member toward a second side opposite a first side on which the contact is provided, and a distal end bent and extending from the proximal end away from the second member.

4. A relay, comprising:
a terminal comprising:
a first member having a leg; and
a second member combined with the first member and having a contact,
wherein the second member has at least three holes, the at least three holes including a middle hole and outer holes located on both sides of the middle hole, respectively,
wherein the first member has at least three protrusions which are individually inserted into and crimped in the at least three holes,
wherein each of the middle hole and the outer holes has an edge closer to the contact, and the edge of the middle hole is arranged so as to be positioned farther from the contact point than a straight line that contacts the edges of the outer holes, and
wherein the leg comprises a proximal end which protrudes from the second member toward a second side opposite a first side on which the contact is provided, and a distal end bent and extending from the proximal end away from the second member, and

a base which supports the terminal, wherein the base comprises:
a bore for guiding the end of the leg to the outside, and
a raised part, having a recess which receives the base of the leg, and which protrudes more outwardly than the bore at a position of the recess.
