Abstract
An electromagnetic crimp terminal includes an electric wire and a terminal plate. The electric wire includes a conductor portion, an insulation portion which covers the conductor portion, and an exposed portion which is a part of the conductor portion exposed from the insulation portion. The terminal plate includes a crimped portion. The crimped portion is crimped onto the exposed portion. The crimped portion includes a first side edge and a second side edge. A vicinity of the first side edge and a vicinity of the second side edge overlap each other.
Claims11
An electromagnetic crimp terminal comprising:
- an electric wire;
- and
- a terminal plate,
- wherein the electric wire includes a conductor portion, an insulation portion which covers the conductor portion, and an exposed portion which is a part of the conductor portion exposed from the insulation portion,
- wherein the terminal plate includes a crimped portion,
- wherein the crimped portion is crimped onto the exposed portion,
- wherein the crimped portion includes a first side edge and a second side edge, and
- wherein a vicinity of the first side edge and a vicinity of the second side edge overlap each other.
A manufacturing method of an electromagnetic crimp terminal, the electromagnetic crimp terminal including an electric wire including a conductor portion whose periphery is covered with an insulation portion and a terminal plate including a crimped portion crimped onto the conductor portion, the manufacturing method comprising:
- preparing the terminal plate including a rectangular flat plate portion to be the crimped portion;
- forming the flat plate portion into a cylindrical portion, and overlapping a vicinity of a first side edge of the cylindrical portion and a vicinity of a second side edge of the cylindrical portion each other, so that the cylindrical portion configure an annular conductive circuit;
- inserting an exposed portion, which is a part of the conductor portion of the electric wire exposed by peeling off a part of the insulation portion, into the cylindrical portion;
- inserting the cylindrical portion into which the exposed portion is inserted into a discharge coil having a substantially C-shaped cross section;
- causing a discharge current to instantaneously flow through the discharge coil;
- and
- reducing a diameter of the cylindrical portion by an electromagnetic force based on an induced current and an induced magnetic field, and conductively crimping the crimped portion onto the exposed portion, wherein the induced current is generated in the cylindrical portion due to the discharge current, and the induced magnetic field is generated between the discharge coil and the cylindrical portion due to the induced current.
A connecting terminal, comprising:
- an electric wire including a conductor portion whose periphery is covered with an insulation portion;
- and
- a terminal plate including a crimped portion to be crimped onto the conductor portion,
- wherein the crimped portion is formed by a rectangular flat plate portion,
- wherein the crimped portion includes a cylindrical portion,
- wherein the cylindrical portion includes a first side edge and a second side edge,
- wherein a vicinity of the first side edge and a vicinity of the second side edge overlap each other,
- wherein the electric wire has an exposed portion which is a part of the conductor portion exposed by peeling off a part of the insulation portion,
- wherein the exposed portion is inserted into the cylindrical portion, and
- wherein the second side edge is in contact with an inner surface of the cylindrical portion near the first side edge.
A connecting terminal, comprising:
- an electric wire including a conductor portion whose periphery is covered with an insulation portion;
- and
- a terminal plate including a crimped portion to be crimped onto the conductor portion,
- wherein the crimped portion is formed by a rectangular flat plate portion,
- wherein the crimped portion includes a cylindrical portion,
- wherein the cylindrical portion includes a first side edge and a second side edge,
- wherein a vicinity of the first side edge and a vicinity of the second side edge overlap each other,
- wherein the electric wire has an exposed portion which is a part of the conductor portion exposed by peeling off a part of the insulation portion,
- wherein the exposed portion is inserted into the cylindrical portion, and
- wherein the first side edge is in contact with an outer surface of the cylindrical portion near the second side edge.
