COAXIAL CONNECTOR

PROBLEM TO BE SOLVED: To mount on a board without using a holding jig by forming a guide groove for fitting into a notch groove of a circuit board. SOLUTION: In a circuit board 280, a coaxial connector 230 is fit into a connector notch part 281 disposed on a position corresponding to the notch part of a frame on the back end side. The connector 230 is consisted of a brass shell 231 having a gold-plated surface and a beryllium copper central contact 233 coaxially embedded on an around hole communicating through the shell 231 through a tef;pm insulator 232. On both sides of the shell 231, a guide groove 234 for fitting into the connector notch part 281. According to this constitution, the connector 230 can be fixed to the circuit board 280 without using a jig when mounted on the circuit board 280 by soldering and workability is facilitated. Additionally, the guide groove 234 is disposed on both sides of the shell 231 so that fixing the connector 320 to the circuit board 280 becomes easy.
