Patent ID: 8747153

Claim:
An electrical coaxial connector comprising; a signal contact member having a connecting terminal portion provided with a pair of holding pieces between which a core conductor of a coaxial cable is tightly held to be electrically connected with the connecting terminal portion and a resilient engaging portion extending from the connecting terminal portion, a grounding contact member having an annular engaging portion for engaging with an annular grounding contact of a mating connector fixed to a circuit board and a shell portion extending to be bendable from the annular engaging portion to be connected with an outer conductor of the coaxial cable, and a housing made of insulator for supporting the signal contact member and the grounding contact member in such a manner that the signal contact member and the grounding contact member are insulated from each other, wherein the resilient engaging portion of the signal contact member is positioned at the inside of the annular engaging portion of the grounding contact member, the connecting terminal portion of the signal contact member is put in electrical connection with the core conductor of the coaxial cable at the outside of the annular engaging portion of the grounding contact member, and the resilient engaging portion of the signal contact member extends from the connecting terminal portion of the signal contact member through the inside of the annular grounding contact of the mating connector to engage with a signal terminal provided on an inside wall of a hole formed on the circuit board to which the mating connector is fixed in such a manner as to press the signal terminal in a first direction perpendicular to a second direction along which the annular engaging portion of the grounding contact member engages with the annular grounding contact of the mating connector when the annular engaging portion of the grounding contact member is put in engagement with the annular grounding contact of the mating connector.
