A power semiconductor device module includes a metal baseplate and a plastic housing that together form a tray. Power electronics are disposed in the tray. A plastic cap covers the tray. Electrical press-fit terminals are disposed along the periphery of the tray. Each electrical terminal has a press-fit pin portion that sticks up through a hole in the cap. In addition, the module includes four mechanical corner press-fit anchors disposed outside the tray. One end of each anchor is embedded into the housing. The other end is an upwardly extending press-fit pin portion. The module is manufactured and sold with the press-fit pin portions of the electrical terminals and the mechanical corner anchors unattached to any printed circuit board (PCB). The mechanical anchors help to secure the module to a printed circuit board. Due to the anchors, screws or bolts are not needed to hold the module to the PCB.

The connecting members are provided to the frame and connect the electrode of the pack. The terminals are provided to the frame and respectively correspond to the connecting members. Each terminal has a fixed segment embedded to the frame, an internal connection segment exposed to the frame and connected with the corresponding connecting member and an external connecting segment extending out of the side of the frame. The adapter circuit board is fixed to the side of the frame and connects with the external connecting segments of the terminals. The connecting unit connects the management and adapter circuit boards.

A terminal fitting having a smaller terminal insertion force than before. The terminal fitting includes a backing material made of a metal material and a plating coating covering a surface of the backing material. The plating coating contains a Sn parent phase and Sn—Pd based particles dispersed in the Sn parent phase and includes an outermost layer having an outer surface in which the Sn parent phase and the Sn—Pd based particles are present. Further, the number of the Sn—Pd based particles present in the outer surface of the plating coating in a state where only the Sn parent phase is removed is 10 to 400 Sn—Pd based particles per 500 μm.sup.2.

A carrier module of a cable connector includes a circuit board and a grounding bar disposed on the circuit board. The circuit board includes a first insulating layer, a second insulating layer, and a grounding layer arranged between the first and second insulating layers. The circuit board has a hole formed on a surface thereof and a conductive extension disposed within the hole, and the conductive extension is connected to the grounding layer. The grounding bar includes a base portion and a conductive portion connected to the base portion. The conductive portion is inserted into the hole, and connected to the conductive extension, thereby electrically connecting the grounding bar and the grounding layer of the circuit board.
