Abstract

Coaxial connector including a center conductor provided inside an outer conductor with a tubular outer conductor main body. A mating portion on one side in the axial direction of the outer conductor main body detachably mates with a counterpart connector. A supporting portion on the other side in the axial direction of the outer conductor main body supports the center conductor through the insulating member medium. Securing portions projecting from the end face on the other side in the axial direction or from the outer peripheral surface on the other side in the axial direction of the outer conductor main body towards the other side in the axial direction securing the outer conductor by soldering to a conductor pattern on the board surface. A first barrier portion on the outer peripheral surface on the other side in the axial direction of the outer conductor main body blocks solder flow.

First claim

What is claimed is:

1. A coaxial connector comprising an outer conductor and a center conductor provided inside the outer conductor,
wherein the outer conductor comprises:
a tubular outer conductor main body;
a mating portion, which is formed on one side in the axial direction of the outer conductor main body and detachably mates with a counterpart connector;
a supporting portion, which is formed on the other side in the axial direction of the outer conductor main body and supports the center conductor through the medium of an insulating member;

securing portions, which project from the end face on the other side in the axial direction or from the outer peripheral surface on the other side in the axial direction of the outer conductor main body towards the other side in the axial direction and secure the outer conductor by soldering to a conductor pattern formed on the surface of the board; and
a first barrier portion, which is formed on the outer peripheral surface on the other side in the axial direction of the outer conductor main body, or on a section located away from the edge on the other side in the axial direction of the securing portions toward one side in the axial direction on the outer peripheral surface of the securing portions, and which blocks the flow of solder;
wherein an expanded portion expanded in the radial direction to a greater extent than the outer peripheral surface on the other side in the axial direction of said outer conductor main body is formed on the other side in the axial direction of the outer conductor main body, and the first barrier portion is formed on the outer peripheral surface of the expanded portion;
wherein solder wettability of the first barrier portion is lower than that of the outer peripheral surface of the securing portions.

2. The coaxial connector according to claim 1 , wherein a second barrier portion that blocks the flow of solder is formed on the end face on the other side in the axial direction of the outer conductor main body.

3. The coaxial connector according to claims 1 , wherein a third barrier portion that blocks the flow of solder is formed on the inner peripheral surface on the other side in the axial direction of the outer conductor main body.

4. The coaxial connector according to claim 1 , wherein a fourth barrier portion that blocks the flow of solder is formed on the inner peripheral surface of the securing portions.

5. The coaxial connector according to claim 1 , wherein the first barrier portion is formed on a section located away from the edge on the other side in the axial direction toward one side in the axial direction on the outer peripheral surface on the other side in the axial direction of the outer conductor main body.

6. The coaxial connector according to claim 1 , wherein two securing portions are formed on the end face on the other side in the axial direction or on the outer peripheral surface on the other side in the axial direction of the outer conductor main body, and the two securing portions are disposed in a mutually spaced relationship in the radial direction of the outer conductor main body.

7. The coaxial connector according to any of claim 1 , wherein four securing portions are formed at intervals in the circumferential direction on the end face on the other side in the axial direction or on the outer peripheral surface on the other side in the axial direction of the outer conductor main body.

8. The coaxial connector according to claim 1 , wherein the securing portions are formed in a C-shaped, U-shaped, or Π-shaped configuration when the outer conductor is viewed from the other side in the axial direction thereof.

9. A coaxial connector comprising an outer conductor and a center conductor provided inside the outer conductor,
wherein the outer conductor comprises:
a tubular outer conductor main body;
a mating portion, which is formed on one side in the axial direction of the outer conductor main body and detachably mates with a counterpart connector;
a supporting portion, which is formed on the other side in the axial direction of the outer conductor main body and supports the center conductor through the medium of an insulating member;

securing portions, which project from the end face on the other side in the axial direction or from the outer peripheral surface on the other side in the axial direction of the outer conductor main body towards the other side in the axial direction and secure the outer conductor by soldering to a conductor pattern formed on the surface of the board; and
a first barrier portion, which is formed on the outer peripheral surface on the other side in the axial direction of the outer conductor main body, or on a section located away from the edge on the other side in the axial direction of the securing portions toward one side in the axial direction on the outer peripheral surface of the securing portions, and which blocks the flow of solder;
wherein a second barrier portion that blocks the flow of solder is formed on the end face on the other side in the axial direction of the outer conductor main body;
wherein solder wettability of the first barrier portion is lower than that of the outer peripheral surface of the securing portions.

10. The coaxial connector according to claim 9 , wherein a third barrier portion that blocks the flow of solder is formed on the inner peripheral surface on the other side in the axial direction of the outer conductor main body.

11. The coaxial connector according to claim 9 , wherein a fourth barrier portion that blocks the flow of solder is formed on the inner peripheral surface of the securing portions.

12. The coaxial connector according to claim 9 , wherein the first barrier portion is formed on a section located away from the edge on the other side in the axial direction toward one side in the axial direction on the outer peripheral surface on the other side in the axial direction of the outer conductor main body.

13. The coaxial connector according to claim 9 , wherein two securing portions are formed on the end face on the other side in the axial direction or on the outer peripheral surface on the other side in the axial direction of the outer conductor main body, and the two securing portions are disposed in a mutually spaced relationship in the radial direction of the outer conductor main body.

14. The coaxial connector according to any of claim 9 , wherein four securing portions are formed at intervals in the circumferential direction on the end face on the other side in the axial direction or on the outer peripheral surface on the other side in the axial direction of the outer conductor main body.

15. The coaxial connector according to claim 9 , wherein the securing portions are formed in a C-shaped, U-shaped, or Π-shaped configuration when the outer conductor is viewed from the other side in the axial direction thereof.
