Abstract

An coaxial connector includes: an insulating housing defining an upper face and a lower face; a first conductor retained in the housing; and a second conductor having a tubular portion surrounding the first conductor, wherein the tubular portion defines a circumferential locking groove at an inner face thereof.

First claim

The invention claimed is:

1 . A coaxial connector comprising:
an insulating housing defining an upper face and a lower face; a first conductor retained in the insulating housing and vertically and upwards extending from the upper face; and a second conductor having a tubular portion surrounding the first conductor; wherein the tubular portion defines a circumferential locking groove at an inner face thereof; and wherein the insulating housing defines a lug portion protruding upwards, and a lower portion of the second conductor fitly surrounds the lug portion.

2 . The coaxial connector as claimed in claim 1 , wherein the tubular portion has three slots opening upwards and passing through the inner face and the outer face of the tubular portion.

3 . The coaxial connector as claimed in claim 2 , wherein the slots extend across the locking groove.

4 . The coaxial connector as claimed in claim 1 , wherein the first conductor comprises a holding portion fixing in the housing, a contacting portion extending upwards and gradually and radially shrinking, a guide portion above the contacting portion, and a neck portion jointing the contacting portion and the guide portion.

5 . The coaxial connector as claimed in claim 4 , wherein the guide portion is of a trumpet shape with an upward opening.

6 . The coaxial connector as claimed in claim 4 , wherein the first conductor defines three slots opening upward and extending downward to the contacting portion, thereby forming an elastic structure.

7 . The coaxial connector as claimed in claim 4 , wherein the locking groove and the neck portion are substantially located at a same horizontal plane.

8 . The coaxial connector as claimed in claim 1 , wherein the first conductor and the second conductor and the insulating housing are insert molded together.
