いた。Conventionally, for example, the signal ground and frame ground of peripheral devices such as computers are generally connected or separated on the computer main body side. however,
Computer peripherals are often shipped separately from the computer, and in that case, the signal ground is switched to frame ground at the time of shipment, and the terminals for connecting the ground and frame ground are thick ( The terminals are provided in a protruding state, which poses a problem in appearance, and the connection of these terminals requires a component called a connecting plate, which is very inconvenient.
そこで、本発明はこれらの欠点に鑑みて改良した新規な
導通装置を提供することを目的とするものである。Therefore, an object of the present invention is to provide a novel conduction device that is improved in view of these drawbacks.

This is a conduction device characterized by being provided within the device body.
以下に本発明の１実施例を図に従って詳細に説明する。An embodiment of the present invention will be described in detail below with reference to the drawings.

Here, transformer cover 2 has fallen to the frame ground. In addition, the signal ground stopper 6 is molded, and the transformer cover 2
It is fixed with screw 5.
