Abstract

A durable coaxial connector (100) for providing a reliable signal connection to a printed circuit board (PCB) (118) while isolating the PCB from mechanical loads that are applied to the connector, and an electrical system incorporating the same. The connector can include a connector body (102) having a connector interface member (106), at least one flange (104), and a ground interface member (304) having a first portion (306) configured to be fixedly attached to the PCB and a second portion (308) configured to slideably mate to a ground interface receptacle defined in the connector body. A connector interface can be defined on an inner surface (410) of the connector interface member. A fastener (124) can couple the connector body to a heat sink (112). A thermally conductive boss (116) can be provided to mount the connector body (102) and transfer thermal energy from the connector body to the heat sink.

Claims

1. A coaxial connector comprising:

a connector body comprising a connector interface member, a flange and a ground interface receptacle;

a ground interface member comprising a first portion configured to be fixedly attached to a printed circuit board and a second portion configured to slideably mate to said ground interface receptacle, said ground interface member comprises a substantially cylindrical radial spring member and at least one slot defined in said radial spring member, wherein said at least one slot facilitates flexure of said radial spring member from a resiliently biased state to facilitate mating of said ground interface member with said ground interface receptacle; and

a conductive contact coaxially aligned with respect to said ground interface member.

2. The coaxial connector of claim 1, wherein said ground interface member provides an electrically conductive ground path to said connector interface member.

3. The coaxial connector of claim 1, wherein said boss is thermally conductive so as to transfer thermal energy from said connector body to said heat sink.

4. The coaxial connector of claim 1, further comprising a connector interface defined on an inner surface of said connector interface member.

5. A coaxial connector comprising:

a connector body comprising a connector interface member, a flange and a ground interface receptacle;

a ground interface member comprising a first portion configured to be fixedly attached to a printed circuit board and a second portion configured to slideably mate to said ground interface receptacle;

a conductive contact coaxially aligned with respect to said ground interface member;

at least one boss which extends from said flange; and

at least one fastener that secures said connector body to a heat sink comprising a planar member such that said flange and said planar member are separated by a distance defined at least in part by said boss.

6. The coaxial connector of claim 5, wherein said boss is thermally conductive so as to transfer thermal energy from said connector body to said heat sink.

7. An electrical system comprising:

a printed circuit board comprising;

a first surface;

a second surface substantially parallel to said first surface;

at least one via defined within said printed circuit board;

a coaxial connector comprising;

a connector body comprising a connector interface member, a flange and a ground interface receptacle;

a conductive contact coaxially aligned with respect to said ground interface member.

8. The electrical system of claim 7, wherein said ground interface member provides an electrically conductive ground path to said connector interface member.

9. The electrical system of claim 7, further comprising a connector interface defined on an inner surface of said connector interface member.

10. The electrical system of claim 7, further comprising:

a heat sink comprising a planar member and at least one boss extending from said planar member;

at least one fastener that secures said connector body to said heat sink such that said flange and said planar member are separated by a distance defined at least in part by said boss.

11. The electrical system of claim 10, wherein said boss is thermally conductive so as to transfer thermal energy from said connector body to said heat sink.

12. An electrical system comprising:

a printed circuit board comprising;

a first surface;

a second surface substantially parallel to said first surface;

at least one via defined within said printed circuit board;

a coaxial connector comprising;

a connector body comprising a connector interface member, a flange and a ground interface receptacle;
