Abstract

In a plug connector, a ground contact conductor includes: a fitting portion to fit to a ground contact conductor of a mate connector; and a clamp portion to hold a second exposing portion of a coaxial cable (a portion of a terminal portion of the coaxial cable where a part of an insulating sheath has been removed) to contact a shield exposed at the second exposing portion, without the ground contact conductor overlapping an outer peripheral surface of the insulating sheath. The clamp portion is located at an end of the ground contact conductor farthest from the fitting portion. The second exposing portion is adjacent to a first exposing portion formed at the terminal portion where a signal line is exposed.

First claim

What is claimed is:

1 . A connector configured to be attached to a coaxial cable having a signal line, a shield, a dielectric layer covering the signal line, a shield covering the dielectric layer, and an insulating sheath covering the shield, the connector comprising:
a signal contact conductor comprising:
a contact portion configured to contact a mate signal contact portion of a mate connector; and
a connection portion configured to connect to the signal line exposed at a first exposing portion formed at a terminal portion of the coaxial cable;
a ground contact conductor comprising:
a fitting portion surrounding the contact portion and configured to fit to a mate ground contact portion of the mate connector; and
a clamp portion configured to hold a second exposing portion of the coaxial cable adjacent to the first exposing portion and contact the shield exposed at the second exposing portion, without the ground contact conductor overlapping an outer peripheral surface of the insulating sheath.

2 . The connector according to claim 1 , wherein the clamp portion is located outside the fitting portion and is configured to hold the second exposing portion such that an axial direction of the signal line intersects a radial center line of the fitting portion.

3 . The connector according to claim 2 , wherein the connection portion is located between the fitting portion and the clamp portion, and wherein the fitting portion is C-shaped to have an opening through which the signal contact conductor passes.

4 . The connector according to claim 3 , further comprising an insulating housing configured to retain the signal contact conductor and the ground contact conductor,
wherein the housing comprises:
a first housing portion configured to hold the contact portion in the fitting portion; and
a second housing portion configured to hold the connection portion between the fitting portion and the clamp portion.

5 . The connector according to claim 4 , wherein the ground contact conductor further comprises a barrel portion configured to hold the second housing portion between the fitting portion and the clamp portion.

6 . The connector according to claim 5 , wherein a gap is formed between the clamp portion and the second housing portion to accommodate a portion of the second exposing portion.

7 . The connector according to claim 6 , wherein the barrel portion is configured to hold the portion of the second exposing portion accommodated in the gap.

8 . The connector according to claim 7 , wherein the barrel portion comprises a barrel base and a barrel arm configured to sandwich the second housing portion between the barrel base and the barrel arm.

9 . The connector according to claim 8 , wherein the ground contact conductor further comprises a holding claw portion projecting from the barrel arm toward the barrel base to press the shield against the dielectric layer.

10 . The connector according to claim 9 , wherein the holding claw portion is located between the second housing portion and the clamp portion and located closer to the clamp portion.

11 . The connector according to claim 8 , wherein a height of the second housing portion located between the barrel base and the barrel arm is smaller than an outer diameter of the second exposing portion.

12 . The connector according to claim 11 , wherein the connection portion comprises a first main surface and a second main surface located opposite side of the connection portion, and
wherein the second housing portion has a first opening configured to expose the first main surface toward the barrel base and a second opening configured to expose the second main surface toward the barrel arm.

13 . The connector according to claim 12 , wherein the signal line of the first exposing portion is connected to the first main surface.

14 . The connector according to claim 13 , wherein a width of the first opening along the axial direction is greater than a width of the second opening along the axial direction.

15 . The connector according to claim 14 , wherein a depth of the first opening perpendicular to the axial direction is greater than a depth of the second opening perpendicular to the axial direction.

16 . The connector according to claim 5 , wherein the ground contact conductor further comprises a pair of arm portions connected to opposite ends of the fitting portion in a circumferential direction, and the barrel portion is configured to hold the pair of arm portions together with the second housing portion.

17 . The connector according to claim 16 , wherein the ground contact conductor has two contacting claw portions configured to press the pair of arm portions against the second housing portion.

18 . The connector according to claim 5 , wherein the ground contact conductor has a plate-shaped portion configured to close one end of the fitting portion without the plate-shaped portion overlapping an outer peripheral surface of the fitting portion, and
wherein the plate-shaped portion extends out of the fitting portion to comprise a part of the barrel portion and a part of the clamp portion.

19 . A method for assembling the connector according to claim 14 , the method comprising:
bringing the signal line of the first exposing portion into contact with a connection portion of a signal contact conductor held by an insulating housing; inserting a supporting tool into the second opening to support the connection portion; inserting a connection tool into the first opening, wherein the signal line contacts the connection portion between the connection tool and the supporting tool; and applying ultrasonic waves, by the connection tool, to provide ultrasonic bonding of the signal line in contact to the connection portion.

20 . A method for assembling a connector on a coaxial cable having a signal line, a dielectric layer covering the signal line, a shield covering the dielectric layer, and an insulating sheath covering the shield, the method comprising:
bringing the signal line exposed at a first exposing portion formed at a terminal portion of the coaxial cable, into contact with a connection portion of a signal contact conductor held by an insulating housing; applying ultrasonic waves for ultrasonic bonding to the signal line in contact with the connection portion; placing a first housing portion of the housing that holds a contact portion of the signal contact conductor in a fitting portion of a ground contact conductor; placing a second housing portion of the housing that holds the connection portion outside the fitting portion; holding a second exposing portion of the coaxial cable adjacent to the first exposing portion, by a clamp portion of the ground contact conductor so that the clamp portion contact the shield exposed at the second exposing portion, without the ground contact conductor overlapping an outer peripheral surface of the insulating sheath; and holding the second housing portion of the housing and a part of the second exposing portion by a barrel portion of the ground contact conductor between the fitting portion and the clamp portion.
