Abstract
A hot pluggable connector of the invention accompanies no physical shock when a circuit package (9) is plugged or unplugged. When the circuit package (9) is inserted, board-side terminals (34) and package-side terminals (52) of the hot pluggable connector are not put in contact. By rotating a rotary body (32) having pads (33A to 33C) of different lengths, sequential connection/disconnection between the board-side terminals (34) and the package-side terminals (52) are performed by way of the pads (33A to 33C). Therefore, it is not necessary to plugging or unplugging the circuit package (9) within a time limit, enabling to insert or remove the circuit package (9) quietly. The timings of the sequential connection/disconnection can be arranged only by arranging length difference of the pads (33A to 33C), enabling to reduce production cost of the hot pluggable connector.
