PROBLEM TO BE SOLVED: To provide a live plug in connector which has a built-in coil for a pre-charging circuit and is equipped with EMC measures. SOLUTION: A live plug in connector 1 is connected to a product substrate 2 with a built-in load circuit 21. The load circuit 21 is pre-charged by a pre- charged circuit 3. Pre-charging is done by charging a capacitor C1 from a power source P2 with a pre-charged terminal 12 by means of a diode 38. A main power source P1 from a main power source terminal 11 is supplied from power source P2 to the load circuit 21 with time difference caused by the delay by a coil 31. Here a connection terminal of the connector 1 connected to a mother board is molded with a plastic material mixed with ferrite powder. The coil 31 is built in the mold section and miniaturized with the magnetic effect of the ferrite powder. The ferrite powder also improves the electromagnetic compatibility between input and output of the terminal 11.
