内の電位にバラツキか生じるという欠点があった。Detailed Description of the Invention (1) Description of the technical field to which the invention pertains The present invention relates to the structure of a power supply connector that supplies power to a printed circuit board of an electronic device. (2) Description of the prior art In recent years, Electronic devices such as computers are becoming smaller and more dense due to the higher integration of semiconductor elements, and as a result, the current consumption per unit volume increases, the current capacity of power supply lines, and power fluctuations. Conventionally, power has been supplied to the printed circuit boards that make up these electronic devices using connectors with a mixture of contact pins for logic signals, but in recent years these have become highly integrated. Connectors used for printed circuit boards have been required to have a multi-pole, high-density structure, and the contact pins have become finer. Current was required, and the voltage drop had to be kept as small as possible, so many contact pins had to be used to supply the current. However, this leads to a decrease in the number of contact bins for logic signals, and as a result, this becomes a factor that hinders the high integration of printed circuit boards.As a means to solve these drawbacks, as shown in Figure 1, printed circuit A method is used in which a large current is supplied by attaching a power receiving plate 2 etc. to the board 1 and fixing it to an external power supply bus 3 with screws 4. In this method, the printed circuit board 1 is a plastic board provided in each mounting unit. A plurality of guides 5 are mounted on the guide 5 manufactured by Manufacturer. However, such a mounting structure has the disadvantage that current concentrates on the screw 4 and generates heat, and since power is supplied from one corner of the printed circuit board 1, the printed circuit board 1
The disadvantage was that there were variations in the potential within the capacitor.
