Terminal connection structure for electric wire
View Patent ↗A terminal connection structure for an electric wire, the electric wire including an internal conductor which is covered with a first insulating cover ( 21 ) and an external conductor which is provided coaxially with the internal conductor to surround an outer circumference of the first insulating cover and covered with a second insulating cover, the terminal connection structure including: a first terminal which is connected to a part where the internal conductor is exposed; a second terminal which is connected to a part where the external conductor is exposed; and an insulating portion which is interposed between the first insulating cover and the second terminal.
1. A terminal connection structure for an electric wire, in which terminals are connected to an internal conductor and an external conductor respectively in the electric wire, the electric wire comprising the internal conductor which is covered with a first insulating cover and the external conductor which is provided coaxially with the internal conductor to surround an outer circumference of the first insulating cover and covered with a second insulating cover, the terminal connection structure comprising:
a first terminal that is connected to a part where the first insulating cover has been peeled to expose the internal conductor;
a second terminal that has a cylindrical shape surrounding an outer circumference of the first terminal and that is connected to a part where the second insulating cover has been peeled to expose the external conductor; and
an insulating portion that has a cylindrical shape and that is arranged between the first insulating cover and the second terminal;
wherein the insulating portion is formed integrally with the second terminal, and is provided in a position corresponding to a connection portion between the part where the external conductor is exposed and the second terminal.
2. The terminal connection structure for an electric wire according to claim 1 , further comprising:
a housing member that comprises a first terminal surrounding portion surrounding the outer circumference of the first terminal, and a second terminal surrounding portion surrounding an outer circumference of the second terminal,
wherein the first terminal and the second terminal are received coaxially at an interval from each other in the housing member; and
wherein the insulating portion is formed to extend from an end portion of the first terminal surrounding portion so as to cover the first insulating cover.
