Coaxial connector

1. A coaxial connector, the coaxial connector comprising:

an outer conductor, the outer conductor engaging an outer conductor of another coaxial connector;

an insulating portion, the insulating portion being arranged on the inside of the outer conductor, the insulating portion including a first fixed portion, a first elastic portion and a second elastic portion, the first elastic portion being positioned on one end of the first fixed portion and moving elastically using the first fixed portion as a pivot, the second elastic portion being positioned on another end of the first fixed portion and moving elastically using the first fixed portion as a pivot; and

an inner conductor, the inner conductor being arranged on the inside of the insulating portion and establishing contact with the outer peripheral surface of the inner conductor of the other coaxial connector, the inner conductor including a second fixed portion, a first holding portion and a second holding portion, the first holding portion being positioned on one side of the second fixed portion, the second holding portion being positioned on another side of the second fixed portion;

wherein:

the first elastic portion biases the outer peripheral surface of the first holding portion towards the outer peripheral surface of the inner conductor of the other coaxial connector; and

the second elastic portion biases the outer peripheral surface of the second holding portion towards the outer peripheral surface of the inner conductor of the other coaxial connector.

2. The coaxial connector of claim 1 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

3. The coaxial conductor of claim 1 , wherein an end portion of the first elastic portion and an end portion of the second elastic portion are separated by a first slit.

4. The coaxial conductor of claim 3 , wherein an end portion of the first holding portion and an end portion of the second holding portion are separated by a second slit, and the first elastic portion, the second elastic portion, the first holding portion are fixed and the second holding portion are fixed.

5. The coaxial connector of claim 3 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

6. The coaxial connector of claim 3 , wherein an opening in the first slit is larger than an opening in the second slit.

7. The coaxial connector of claims 6 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

8. The coaxial connector of claim 3 , wherein the first slit and the second slit are positioned in the same direction from the first fixed portion.

9. The coaxial connector of claim 8 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

10. The coaxial connector of claim 8 , wherein an opening in the first slit is larger than an opening in the second slit.

11. The coaxial connector of claim 10 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

12. The coaxial conductor of claim 3 , wherein the insulating portion has an arcuate plan view profile connecting the first elastic portion and the second elastic portion, and has a C-shaped plan view profile connecting the first elastic portion, the first fixed portion and the second elastic portion.

13. The coaxial conductor of claim 12 , wherein the inner conductor has an arcuate plan view profile connecting the first holding portion and the second holding portion, and has a C-shaped plan view profile connecting the first holding portion, the second fixed portion and the second holding portion.

14. The coaxial connector of claim 12 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

15. The coaxial connector of claim 12 , wherein an opening in the first slit is larger than an opening in the second slit.

16. The coaxial connector of claim 15 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

17. The coaxial connector of claim 12 , wherein the first slit and the second slit are positioned in the same direction from the first fixed portion.

18. The coaxial connector of claim 17 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.

19. The coaxial connector of claim 17 , wherein an opening in the first slit is larger than an opening in the second slit.

20. The coaxial connector of claim 19 , wherein a portion of the outer peripheral surface of the elastic portions engages a portion of the inner peripheral surface of the outer conductor.
