別個に備えた場合には、ヒューズおよび接続導体の設置
スペースの分だけ電気装置の寸法が大きくなり、とくに
配電盤のようにその内部に電気機器を収納する電気装置
の場合にその小型化を妨げる。When the fuses are separately provided as described above, the size of the electric device is increased by the space for installing the fuses and the connecting conductors, and especially the electric device inside the electric device such as a switchboard. In the case of an electric device that houses a device, it hinders its miniaturization.
【０００５】この発明の目的は、ケーブル引出ブッシン

ューズとして筒型ヒューズが採用される。In order to achieve this object, the present invention comprises a bushing and a conductor penetrating through the bushing, which is mounted on a container of an electric device to connect a connecting conductor of the electric device to the outside. In a cable pull-out bushing to be pulled out, the conductor inside the bushing is divided into a conductor inside the electric device and a conductor outside the electric device, and a fuse is embedded in the bushing, and one terminal of the fuse is a conductor inside the electric device. In addition, the other terminal is connected to the external conductor. In the above structure, a cylindrical fuse is adopted as the fuse.

ヒューズとの機能を持たせることができる。According to the structure of the present invention, the conductor in the bushing is divided into the conductor on the inner side and the conductor on the outer side of the electric device, and the fuse is embedded in the bushing, and one terminal of the fuse is connected to the electric device. Since the other terminal is connected to the outer conductor of the inner conductor, the function of the cable leading bushing and the fuse can be provided only by the space of the cable leading bushing.

In FIG. 1, the bushing 1 is made of an insulating material and is attached to the container of an electric device by its flange. A tubular fuse 2 is embedded in the bushing 1, one terminal of which is connected to a conductor 3 on the inner side of the electric device and the other terminal of which is connected to a conductor 4 on the outer side.
