Abstract

A shield terminal includes a contact part surrounding a center terminal and a dielectric body and configured to come into contact with a terminal of a target connector, a connecting part surrounding a shield wire and connected to the shield wire, and a catching-target part surrounding a coaxial cable. The contact part, the connecting part, and the catching-target part are bent and formed integrally into a cylindrical shape to surround a center line of the coaxial cable. A housing includes, inside an insertion hole, a catching face configured to come into contact with a part of a front edge of the catching-target part to restrict the shield terminal from moving forward.

First claim

a housing formed with an insertion hole passing through in a front-rear direction to accommodate the center terminal, the dielectric body, and the shield terminal, the center terminal, the dielectric body, and the shield terminal configured to be inserted into the housing from a rear side of the insertion hole,
wherein the shield terminal includes:
a contact part surrounding the center terminal and the dielectric body, the contact part being configured to come into contact with a terminal of a target connector;
a connecting part configured to surround the shield wire of the coaxial cable, the connecting part configured to be connected to the shield wire of the coaxial cable; and
a catching-target part configured to surround the coaxial cable,
wherein the contact part, the connecting part, and the catching-target part are bent and formed integrally into a cylindrical shape so as to be configured to surround a center line of the coaxial cable, and
wherein the housing includes, inside the insertion hole, a catching part configured to come into contact with a part of a front edge of the catching-target part to restrict the shield terminal from moving forward,
wherein the catching-target part of the shield terminal lies behind the connecting part.

2. The coaxial connector according to claim 1 , wherein the contact part of the shield terminal includes:
a main body surrounding the center terminal and the dielectric body; and
a rearmost part lying behind the main body and configured to surround the shield wire.

3. The coaxial connector according to claim 1 ,
wherein the catching part of the housing is configured to surround the center line of the coaxial cable, and
wherein the catching-target part of the shield terminal is rotatable over 360 degrees relative to the catching part about the center line of the coaxial cable.

4. The coaxial connector according to claim 1 , wherein the catching-target part is configured to lie outside the shield wire.

5. The coaxial connector according to claim 1 , wherein at least a part of the catching-target part in the circumferential direction about the center line of the coaxial cable is configured to be away from an outer face of the coaxial cable.

6. A coaxial connector comprising:
a center terminal which is configured to be connected to a core wire of a coaxial cable;
a shield terminal which is configured to be connected to a shield wire of the coaxial cable;
a dielectric body externally surrounding the center terminal, the dielectric body being disposed between the center terminal and the shield terminal; and
a housing formed with an insertion hole passing through in a front-rear direction to accommodate the center terminal, the dielectric body, and the shield terminal, the center terminal, the dielectric body, and the shield terminal configured to be inserted into the housing from a rear side of the insertion hole,
wherein the shield terminal includes:
a contact part surrounding the center terminal and the dielectric body, the contact part being configured to come into contact with a terminal of a target connector;
a connecting part configured to surround the shield wire of the coaxial cable, the connecting part configured to be connected to the shield wire of the coaxial cable; and
a catching-target part configured to surround the coaxial cable,
wherein the contact part, the connecting part, and the catching-target part are bent and formed integrally into a cylindrical shape so as to be configured to surround a center line of the coaxial cable, and
wherein the housing includes, inside the insertion hole, a catching part configured to come into contact with a part of a front edge of the catching-target part to restrict the shield terminal from moving forward,
wherein the catching-target part includes:
at a part of the catching-target part in a circumferential direction about the center line of the coaxial cable, a first curved part connected to the connecting part and curved about the center line; and
a second curved part at another part of the catching-target part in the circumferential direction,
wherein a distance from the center line to the second curved part is longer than a distance from the center line to the first curved part, and
wherein a front edge of the second curved part is in contact with the catching part of the housing.

7. The coaxial connector according to claim 6 ,
wherein the catching part of the housing is configured to surround the center line of the coaxial cable, and
wherein the catching-target part of the shield terminal is rotatable over 360 degrees relative to the catching part about the center line of the coaxial cable.

8. The coaxial connector according to claim 6 , wherein the catching-target part is configured to lie outside the shield wire.

9. The coaxial connector according to claim 6 , wherein at least a part of the catching-target part in the circumferential direction about the center line of the coaxial cable is configured to be away from an outer face of the coaxial cable.

10. A coaxial connector comprising:
