An electrical connector assembly includes an electrical connector and a pick up cap. The network routes a cell transmitted by an input module to an output module, in the case of a cell of a unicast flow; the network routes a cell transmitted by an input module to N output modules in the case of a cell of a multicast flow, by generating itself the N copied cells from the transmitted cell. When the comparator detects that the current of the motor is increased to the target current value, the holding circuit holds the circuit state such that the switch unit is turned off. The intermediate film 6 is formed of an Ru alloy. The remote access message is sent to the data center to initiate request for access to the postage security account by the remote user device.
