Shield connector
It is aimed to reduce friction resistance generated in a resilient contact portion. A shield connector is provided with a dielectric for accommodating an inner conductor, a tubular outer conductor for surrounding the dielectric, a resilient contact portion formed in the outer conductor, and a cut portion formed in the outer conductor and enabling a supporting portion supporting the resilient contact portion, out of the outer conductor, to be resiliently deformed. If the resilient contact portion contacts a mating outer conductor and is resiliently deformed, the supporting portion supporting the resilient contact portion is resiliently deformed by a reaction force from the mating outer conductor. Since a resilient deformation amount of the resilient contact portion is reduced by as much as the supporting portion is resiliently deformed, friction resistance generated in the resilient contact portion is reduced.
1. A shield connector, comprising:
a dielectric for accommodating an inner conductor;
an outer conductor having a tubular shape surrounding the dielectric;
a resilient contact portion formed in the outer conductor;
a supporting portion formed out of the outer conductor and configured to support the resilient contact portion; and
a cut portion formed in the outer conductor and configured to enable the supporting portion to be resiliently deformed,
wherein:
the supporting portion is in the form of a rectangular tube having four plate portions in the form of flat plates,
the cut portion is in the form of a slit formed by cutting a boundary between the plate portions perpendicular and adjacent to each other,
the resilient contact portion is formed in at least one of the plate portions and projects outwardly of the supporting portion, and
the supporting portion is resiliently deformed as the resilient contact portion is resiliently deformed.
2. The shield connector according to claim 1 , wherein:
the cut portion includes a pair of cut portions formed to sandwich the plate portion in a width direction, and
the resilient contact portion is symmetrically shaped with respect to a widthwise center line of a corresponding one of the plate portions.
3. The shield connector according to claim 1 , wherein the resilient contact portion is elongated in a front-rear direction in parallel to an axis of the outer conductor and both front and rear end parts thereof are connected to the supporting portion.
4. The shield connector according to claim 1 , wherein:
the cut portion includes a plurality of cut portions arranged at intervals in a circumferential direction around an axis of the outer conductor as not to communicate with each other.
5. A shield connector, comprising:
a dielectric for accommodating an inner conductor;
an outer conductor having a tubular shape surrounding the dielectric;
a resilient contact portion formed in the outer conductor;
a supporting portion formed out of the outer conductor and configured to support the resilient contact portion; and
a cut portion formed in the outer conductor and configured to enable the supporting portion to be resiliently deformed,
wherein:
the resilient contact portion is elongated in a front-rear direction in parallel to an axis of the outer conductor and both front and rear end parts thereof are connected to the supporting portion,
the resilient contact portion is bent into a chevron shape,
a bent part of the resilient contact portion functions as a contact point portion,
a part of the resilient contact portion from a front end of the resilient contact portion to the contact point portion is a front inclined portion that projects outwardly of the supporting portion, and
a part of the resilient contact portion from the contact point portion to a rear end of the resilient contact portion is a rear inclined portion that projects outwardly of the supporting portion,
a length of the front inclined portion is shorter than that of the rear inclined portion,
the front inclined portion is higher in rigidity than the rear inclined portion, and
the cut portion is formed only in a region forward of the contact point portion in the front-rear direction.
6. A shield connector, comprising:
a dielectric for accommodating an inner conductor;
an outer conductor having a tubular shape surrounding the dielectric;
a resilient contact portion formed in the outer conductor;
a supporting portion formed out of the outer conductor and configured to support the resilient contact portion; and
a cut portion formed in the outer conductor and configured to enable the supporting portion to be resiliently deformed,
wherein:
a pair of slits extending in a front-rear direction are formed in a plate portion constituting the supporting portion,
the resilient contact portion is formed by a part of the plate portion between the pair of slits, and
the slits are entirely surrounded by a mating member ( 40 ) with the outer conductor fit to the mating member.
