Standoff board-mounted coaxial connector
First Claim
1. A coaxial connector that has inner and outer contacts, where the connector has a board-mount end for mounting on a circuit board and connecting said contacts to circuit board traces, wherein:
- at said board-mount end of said connector, said inner contact comprises a pin part extending along an axis and said outer contact has an electrically conductive standoff with a bottom for lying on said circuit board, with said standoff extending at least partially around said pin part, and with said standoff forming at least 120°
of a primarily circular inner surface that faces said pin part and that is coaxial with said axis.

Abstract
A coaxial connector has a board mount end (14) for mounting on a circuit board, with a standoff (70) thereat to lie above circuit board traces and allow the passage of wash fluid that washes away soldering flux etc., which minimizes a change in impedance along the standoff to reduce signal losses. The standoff, which is connected to the outer contact (24) of the connector, has a circular inner surface (90) that faces the pin part (34) of the center contact, and which has segments (81-84) which, together, extend at least about 180° about the pin. The outer contact which surrounds a mount-end insulator (62) and the inner contact, has a slot (120) at the mount end to enable the installation of the center contact.

3. A combination of a coaxial connector and a circuit board, where the connector has inner and outer contacts, a mount end mounted on the circuit board and an opposite mate end, and where the circuit board has a surface, a plurality of board holes, and a plurality of traces extending along said surface from said board holes, wherein:
-
said mount end of said inner contact forms a pin part that projects along an axis into one of said board holes and said mount end of said outer contact includes a plurality of posts lying around said pin part and projecting into a plurality of said holes; said mount end of said outer contact also has a standoff with a lower end lying on said circuit board with said standoff having a plurality of passages with at least one lying above one of said traces, with parts of said standoff extending between said passages forming a surface that includes at least 120°
of a circle concentric with said axis, as viewed along said axis.
