ある。For this reason, in conventional printed wiring boards, the contact position that contacts the female contact of the mating connector is the same as any male contact, so if you accidentally insert or remove the printed wiring board while power is being supplied to the connector side. If you do so, the power supply ground wire may come off first, or power may be supplied to the electrical circuit on the printed wiring board before the power supply ground wire is connected, resulting in damage to the electrical circuit. be.
本発明の目的は配線板の挿抜に伴う該配線上の電気回路
の破損を防止する印刷配線板を提供することにある。An object of the present invention is to provide a printed wiring board that prevents damage to electric circuits on the wiring caused by insertion and removal of the wiring board.

である。The present invention forms male contacts on a printed wiring board and connects the male contacts directly to a female connector, thereby establishing signal and power connections between the electrical circuit configured on the printed wiring board and other circuits. The printed wiring board is characterized in that the shape of the contact assigned to the ground of the power source among the male contacts is longer than the other contacts in the insertion/extraction direction of the printed wiring board.
次に本発明の一実施例について図面を参照して説明する
。Next, an embodiment of the present invention will be described with reference to the drawings.

いる。FIG. 1 shows an embodiment of the invention. As shown in FIG. 1, male contacts 2 and 3 are formed on the printed wiring board 1, but the male contact 2 assigned to the ground of the power supply is larger in the insertion/removal direction of the printed wiring board 1 than the other male contacts 3. A is longer and has male contact 2.
extends outward from the other male contacts 3.

を破壊することがないという効果がある。As explained above, the printed wiring board of the present invention has a male contact that connects the ground wire of the power source of the electric circuit configured on the printed wiring board, and the shape of the male contact is compared to that of the male contact used to connect other signals. When this printed wiring board is inserted into a connector by elongating it in the connection direction, the ground wire is connected first, and when it is removed from the connector, the ground wire is removed last. By doing this, even if the printed wiring board is accidentally inserted or removed while power is being supplied to the connector, the electrical circuit configured on the printed wiring board will not be destroyed. There is.
