Insulating structure for L-shaped terminal
View Patent ↗To electromagnetically-shield an L-shaped terminal in a compact and reliable manner while easily and securely fixing the L-shaped terminal, there is employed an insulating split inner housing having an L-shaped terminal receiving portion including an electric-contact-portion-side receiving portion covering an electric contact portion of the L-shaped terminal connected to a shielded wire and a wire-connection-portion-side receiving portion covering a wire connection portion of the L-shaped terminal, the electric-contact-portion-side receiving portion is covered by a conductive shield shell, the wire-connection-portion-side receiving portion is covered by a conductive housing connected to the shield shell and to a shield portion of the shielded wire, and the L-shaped terminal is insulated by the inner housing from the shield shell and the conductive housing.
1. An insulating structure for L-shaped terminal comprising
an insulating split inner housing comprising a plurality of L-shaped terminal receiving portions including
an electric-contact-portion-side receiving portion covering an electric contact portion of the L-shaped terminal connected to a shielded wire, and
a wire-connection-portion-side receiving portion covering a wire connection portion of the L-shaped terminal,
wherein
a plurality of the electric-contact-portion-side receiving portions is covered and received by a conductive shield shell,
a plurality of the wire-connection-portion-side receiving portions is covered by a conductive housing,
the conductive housing is connected to the shield shell and to a shield portion of the shielded wire,
the inner housing insulates the L-shaped terminal from the shield shell and the conductive housing, and
the shield shell and tip end portions of the plurality of electric-contact-portion-side receiving portions projecting from the shield shell are covered by an insulating outer housing, and
wherein while a flange of the inner housing projected in a radial direction in between the electric-contact-portion-side receiving portion and the wire-connection-portion-side receiving portion is held between a flange of the conductive housing and a flange of the shield shell projected in the radial direction, a flange of the outer housing projected in the radial direction is fixed to the flange of the conductive housing via the flange of the shield shell with a bolt.
2. The insulating structure for L-shaped terminal according to claim 1 , wherein each of the plurality of inner housings includes the single terminal receiving portion and is designed to split in a widthwise direction of the L-shaped terminal.
3. The insulating structure for L-shaped terminal according to claim 2 , wherein the shield portion of the shielded wire is connected to the conductive housing through a shield terminal, and the shield terminal is arranged close to and along the wire-connection-portion-side receiving portion of the inner housing.
4. The insulating structure for L-shaped terminal according to claim 1 , wherein the single inner housing includes the plurality of terminal receiving portions attached to each other in a parallel manner, and the inner housing is designed to split in a thickness direction of the L-shaped terminal.
5. The insulating structure for L-shaped terminal according to claim 4 , wherein the shield portion of the shielded wire is connected to the conductive housing through a shield terminal, and the shield terminal is arranged close to and along the wire-connection-portion-side receiving portion of the inner housing.
6. The insulating structure for L-shaped terminal according to claim 1 , wherein the shield portion of the shielded wire is connected to the conductive housing through a shield terminal, and the shield terminal is arranged close to and along the wire-connection-portion-side receiving portion of the inner housing.
