Abstract

An electrical coaxial connector comprising a signal-joining contacting conductor having a body portion to be connected with a signal joining conductor of a mating coaxial connector, a grounding contacting conductor having an annular portion placed around the body portion of the signal joining contacting conductor to be connected with a grounding conductor of the mating coaxial connector, and an insulating base member for supporting the signal-joining contacting conductor and the grounding contacting conductor to be isolated from each other, wherein the body portion of the signal-joining contacting conductor is formed into a cylindrical shape with a slit extending to surround an imaginary central axis of the cylindrical shape of the body portion and provided with a base part and an engaging part opposite to each other with the slit between and connected with each other by a connecting part of the body portion at which the slit is not formed.

First claim

The invention claimed is:

a signal-joining contacting conductor having a body portion provided to be electrically connected with a signal-joining conductor of a mating coaxial connector and a signal-joining terminal portion extending from the body portion,
a grounding contacting conductor having an annular portion placed around the body portion of the signal joining contacting conductor to be electrically connected with a grounding conductor of the mating coaxial connector and a grounding terminal portion extending from the annular portion, and
an insulating base member in which each of the signal-joining terminal portion of the signal-joining contacting conductor and the grounding terminal portion of the grounding contacting conductor is partially buried and which supports the signal joining contacting conductor and the grounding contacting conductor to be isolated from each other,
wherein the body portion of the signal-joining contacting conductor is formed into a cylindrical shape and provided with a slit extending to surround an imaginary central axis of the cylindrical shape of the body portion,
wherein the body portion of the signal joining contacting conductor is further provided with a base part and an engaging part which are opposite to each other with the slit between the base part and the engaging part and connected with each other by a connecting part of the body portion at which the slit is not formed,
wherein the base part of the body portion is partially buried in the insulating base member, and
wherein the engaging part of the body portion constitutes a resilient annular part with at least one break for engaging resiliently with the signal joining conductor of the mating connector.

2. An electrical coaxial connector according to claim 1 , wherein the signal-joining terminal portion of the signal-joining contacting conductor is configured to extend from the base part of the body portion of the signal joining contacting conductor.

3. An electrical coaxial connector according to claim 1 , wherein the resilient annular part constituted with the engaging part of the body portion of the signal-joining contacting conductor has an oval cross-section on a plane perpendicular to the imaginary central axis of the cylindrical shape of the body portion.

4. An electrical coaxial connector according to claim 1 , wherein the resilient annular part constituted with the engaging part of the body portion of the signal-joining contacting conductor is provided on the inside surface thereof with a plurality of contact points for coming into contact with the signal-joining conductor of the mating coaxial connector.

5. An electrical coaxial connector according to claim 1 , wherein the engaging part of the body portion of the signal-joining contacting conductor has first and second curved arms extending respectively in opposite directions to surround the imaginary central axis of the cylindrical shape of the body portion, and a free end of the first curved arm and a free end of the second curved arm are opposite to come close to each other, so that the break on the resilient annular part constituted with the engaging part is formed between the free end of the first curved arm and the free end of the second curved arm.

6. An electrical coaxial connector according to claim 5 , wherein the free end of the first curved arm and the free end of the second curved arm coming close to each other are positioned to be opposite to the connecting part of the body portion with the imaginary central axis of the cylindrical shape of the body portion between each of the free ends of the first and second curved arms and the connecting part of the body portion.

7. An electrical coaxial connector according to claim 1 , wherein the connecting part of the body portion of the signal-joining contacting conductor is configured to have first and second connecting parts separated from each other in a direction surrounding the imaginary central axis of the cylindrical shape of the body portion; the engaging part of the body portion is configured to have first and second curved arms extending from the first connecting part respectively in opposite directions to surround the imaginary central axis of the cylindrical shape of the body portion and third and fourth curved arms extending from the second connecting part respectively in opposite directions to surround the imaginary central axis of the cylindrical shape of the body portion; a free end of the first curved arm and a free end of the third curved arm are opposite to come close to each other, so that the break on the resilient annular part constituted with the engaging part is formed between the free end of the first curved arm and the free end of the third curved arm; and a free end of the second curved arm and a free end of the fourth curved arm are opposite to come close to each other, so that the break on the resilient annular part constituted with the engaging part is formed between the free end of the second curved arm and the free end of the fourth curved arm.

8. An electrical coaxial connector according to claim 7 , wherein the first and second connecting parts are positioned to be opposite to each other with the imaginary central axis of the cylindrical shape of the body portion between the first and second connecting parts.

9. An electrical coaxial connector according to claim 8 , wherein the free ends of the first and third curved arms coming close to each other and the free ends of the second and fourth curved arms coming close to each other are positioned to be opposite to each other with the imaginary central axis of the cylindrical shape of the body portion between each of the free ends of the first and third curved arms and each of the free ends of the second and fourth curved arms.

10. An electrical coaxial connector according to claim 1 , wherein the connecting part of the body portion of the signal-joining contacting conductor is configured to have first and second connecting parts separated from each other in a direction surrounding the imaginary central axis of the cylindrical shape of the body portion; the engaging part of the body portion is configured to have a first curved arm extending from the first connecting part to surround the imaginary central axis of the cylindrical shape of the body portion and a second curved arm extending from the second connecting part to surround the imaginary central axis of the cylindrical shape of the body portion; a free end of the first curved arm is opposite to the second connecting part for coming close to the second connecting part, so that the break on the resilient annular part constituted with the engaging part is formed between the free end of the first curved arm and the second connecting part; and a free end of the second curved arm is opposite to the first connecting part for coming close to the first connecting part, so that the break on the resilient annular part constituted with the engaging part is formed between the free end of the second curved arm and the first connecting part.
