ことが可能である。[Effects of the invention] As explained above, the external power plug according to the invention has good workability because the sleeve, which was conventionally made by cutting or drawing, is made by curling a metal plate into a cylindrical shape. Costs can be reduced.
In addition, each part has a structure that can be automatically processed, and assembly can be done only by inserting and clamping, so not only does it require no skill, but it also makes it easy to produce products with stable quality and high production yields. It also has the effect of being covered. Furthermore, since the contact portion of the shaft contact piece is formed into a non-cylindrical shape by bending an elastic flat plate, the jack shaft can be elastically and reliably contacted in the inscribed space, and the relative relationship with the inner insulating member can be reduced. Since rotation is restricted, even if the entire plug is rotated during engagement and insertion into the jack, twisting and breaking of the wire at the clamp portion can be prevented. In addition, the axial and rotational positions of each component are well controlled, and the insulation coating is firmly clamped at the same time as the core wire and ground wire are connected, providing sufficient strength against twisting and tension. It is possible to hold.

体を設けたことを特徴とする外部電源プラグ。 A core wire clamp part that bends a conductive elastic flat plate and crimps the core wire of the electric wire, a covering clamp part that crimps the insulation coating of the core wire, a shaft contact piece that forms a non-cylindrical contact part, and the contact. an inner insulating member that non-rotatably accommodates the ground wire; an earth clamp portion that crimp the ground wire of the electric wire by bending a conductive elastic flat plate; a covering clamp portion that crimp the insulation coating of the ground wire; and the inner insulation member. It consists of a sleeve formed with a contact portion that fits around the member, an outer insulating member that surrounds the outside of the sleeve, and an insulating cover that fits on the outside of the outer insulating member, and the outer insulating member has a hinge. It consists of two half-cylindrical parts that can be opened and closed in a half-shape connected at a portion, and inside these half-cylindrical parts there are protrusions that regulate the positions of the shaft contact piece, the inner insulating member, and the sleeve in the axial direction and rotational direction. An external power plug is provided.
