Shielded terminal
The present invention prevents a cover from being incorrectly installed with respect to an external conductor. This shielded terminal is provided with: an external conductor ( 20 ) that has a connection space ( 28 ) which is between a pair of side walls ( 26 ), and which is open to the outside via a first opening ( 31 ) and a second opening ( 32 ); a shielded electric cable ( 70 ) that is connected to the external conductor ( 20 ); an internal conductor ( 11 ) that is housed in the external conductor ( 20 ) and that is connected to a core wire ( 71 ) of the shielded electric cable ( 70 ) in the connection space ( 28 ); and a cover ( 50 ) that is installed inside the connection space ( 28 ) from the first opening ( 31 ) and that surrounds the part at which the core wire ( 71 ) and the internal conductor ( 11 ) are connected, wherein an interference part ( 34 ) that interferes with the cover ( 50 ) is formed on the opening edge part of the second opening ( 32 ).
1. A shielded terminal comprising:
an outer conductor that includes a connection space sandwiched between a pair of side wall portions, and in which the connection space is open to the outside via a first opening portion and a second opening portion;
a shielded electrical wire connected to the outer conductor;
an inner conductor housed in the outer conductor and connected to a core wire of the shielded electrical wire in the connection space; and
a cover member that is attached within the connection space through the first opening portion, and surrounds a connection portion between the core wire and the inner conductor,
wherein an opening edge portion of the second opening portion is provided with an interference portion configured to interfere with the cover member,
wherein the interference portion is formed so as to extend along at least one of a front edge portion and a rear edge portion of the second opening portion,
the cover member includes a pair of side plate portions that are arranged so as to extend along inner surfaces of the pair of side wall portions, and surround the connection portion between the core wire and the inner conductor, and
a front-rear length of the pair of side plate portions is set to a length greater than a front-rear opening length of the second opening portion,
wherein a protrusion is formed on an insertion edge portion on a leading end of the pair of side plate portions in a direction in which the side plate portions are inserted into the first opening portion, and
the protrusion is disposed in a region that does not correspond to the interference portion in a front-rear direction.
2. The shielded terminal according to claim 1 ,
wherein the interference portion bridges the pair of side wall portions.
3. The shielded terminal according to claim 1 ,
wherein the interference portion is formed so as to extend along at least one of a front edge portion and a rear edge portion of the second opening portion,
the pair of side plate portions are arranged so as to extend along inner surfaces of the pair of side wall portions, and surround the connection portion between the core wire and the inner conductor, and
a front-rear length of the pair of side plate portions is set to a length greater than a front-rear opening length of the second opening portion.
4. The shielded terminal according to claim 1 ,
wherein the outer conductor has a crimping shielding portion that is crimped to a shielding layer of the shielded electrical wire, and
the interference portion is continuous with the side wall portions and the crimping shielding portion.
5. The shielded terminal according to claim 4 ,
wherein the crimping shielding portion includes:
a pair of support wall portions that are respectively diagonally continuous with rear edge portions of the pair of side wall portions; and
a bottom wall portion that links the pair of support wall portions to each other on a rear side of the second opening portion, and
the interference portion is formed so as to bridge the pair of side wall portions and to be continuous with the bottom wall portion over the entire length thereof.
6. A shielded terminal comprising:
an outer conductor that includes a connection space sandwiched between a pair of side wall portions, and in which the connection space is open to the outside via a first opening portion and a second opening portion;
a shielded electrical wire connected to the outer conductor;
an inner conductor housed in the outer conductor and connected to a core wire of the shielded electrical wire in the connection space; and
a cover member that is attached within the connection space through the first opening portion, and surrounds a connection portion between the core wire and the inner conductor,
wherein an opening edge portion of the second opening portion is provided with an interference portion configured to interfere with the cover member,
wherein the cover member includes a pair of side plate portions, and
wherein a protrusion is formed on an insertion edge portion on a leading end of the pair of side plate portions in a direction in which the side plate portions are inserted into the first opening portion.
7. The shielded terminal according to claim 6 ,
wherein the interference portion bridges the pair of side wall portions.
8. The shielded terminal according to claim 6 ,
wherein the outer conductor has a crimping shielding portion that is crimped to a shielding layer of the shielded electrical wire, and
the interference portion is continuous with the side wall portions and the crimping shielding portion.
9. The shielded terminal according to claim 8 ,
wherein the crimping shielding portion includes:
a pair of support wall portions that are respectively diagonally continuous with rear edge portions of the pair of side wall portions; and
a bottom wall portion that links the pair of support wall portions to each other on a rear side of the second opening portion, and
the interference portion is formed so as to bridge the pair of side wall portions and to be continuous with the bottom wall portion over the entire length thereof.
