A printing material container is detachably attachable to a printing apparatus having a plurality of apparatus-side terminals. The printing material container comprises a first device, a second device, and a terminal group that includes a plurality of first terminals, at least one second terminal and at least one third terminal. The plurality of first terminals are connected to the first device and respectively include a first contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one second terminal is connected to the second device and includes a second contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one third terminal is for the detection of shorting between the at least one second terminal and the at least one third terminal and includes a third contact portion for contacting a corresponding terminal among the plurality of apparatus-side terminals. The at least one second contact portion, the plurality of the first contact portions, and the at least one third contact portion are arranged so as to form one or multiple rows. The at least one second contact portion is arranged at an end of one row among the one or multiple rows.

The present invention generally relates to the field of telecommunication, and more particularly, to the field of connectors such as plugs and/or jacks used to interconnect electronic equipment. In an embodiment, the present invention is a shielded RJ45 network jack with an inter-jack connection method that has an electrical disengagement point outside of any electrical mating points, while still allowing for a relatively short distance to compensation from the plug/jack mating interface.

An electronic unit attaching structure includes an electronic unit (30) having a plurality of connector connection portions (33, 34) and an electronic unit attachment (20) having a plurality of connectors (C1, C2) correspond to the plurality of the connector connection portions. The electronic unit attaching structure is configured to allow first connection and second connection in this order when the electronic unit (30) is attached to the electronic unit attachment (20). The first connection is a connection of first part (C2) of the plurality of the connectors with first part (34) of the plurality of the connector connection portions. The second connection is a connection of second part (C1) of the plurality of the connectors with second part (33) of the plurality of the connector connection portions.

An electrical connector is provided for both power and data transmission. The electrical connector comprises an electrical plug (100) having a plurality of pins (131-138) and an electrical socket (200) having a plurality of passageways (220) which are arranged corresponding to the plurality of pins (131138). The pins (131138) of the plug comprise at least one signal pin (131, 136), two or more positive power pins (133, 134) and two or more negative power pins (132, 135). The pins (131138) of the plug can be disposed such that the positive power pins (133, 134) and the at least one signal pin (131, 136) are positioned on opposite sides of the negative power pins (132, 135).
