Abstract
PURPOSE:To abate the extent of induction between pins themselves of a connector and an external unit or the like by giving a shield function to a connector retaining device in a way of making potential in the connector keeping device equal to earth potential of a substrate. CONSTITUTION:Connectors 3a, 3b and 3c are attached to a end of a circuit element mounting substrate 6, and these connectors 3a, 3b and 3c are pressed down by a connector retaining device 4 which is screwed down to the substrate 6. A screw inserting hole inner wall in the substrate, there is provided with a conductive surface 9 which is connected to an earth line 8 formed on a surface of the substrate 6 and a round 7 formed in the backside of the substrate 6. With this constitution, a shield function is giveable to the presser device 4. It is thus possible to abut the extent of induction between pins themselves of the connector and an external device.
