The utility model content

The utility model technical problem to be solved is to overcome the deficiency of above-mentioned prior art; Provide a kind of littler, whole structure of back volume of installing better and make bus connecting device have the bus connecting device of better fail safe, and it is tangible to reach all insulation of all devices through ground hole is set.

The main technical schemes that a kind of bus connecting device that provides according to the utility model adopts is: comprise a plurality of electric cable accessoriess and the bus that connects said electric cable accessories; Said bus comprises conductor, is coated on first insulating barrier on the said conductor and is coated on first semiconductor layer on first insulating barrier; Said electric cable accessories comprise inner semiconductor layer and outer semiconductor layer and be arranged on inner semiconductor layer and said outer semiconductor layer between second insulating barrier, said outer semiconductor layer is connected with said first semiconductor.

A kind of bus connecting device that the utility model provides also can have following attached technical characterictic:

On said first semiconductor layer and the outer semiconductor layer ground hole is set all, said ground hole ground connection.

Said bus is provided with kink, and said first semiconductor coats said kink.

Said second insulating barrier adopts the ethylene-propylene diene copolymer casting to form.

The thickness of said first semiconductor layer is 2mm.

Said first insulating barrier adopts silicon rubber to process.

The thickness of said first insulating barrier is 11.5mm.

Said conductor is a copper rod, and said conductor part stretches out outside said first insulating barrier.

The part that said conductor stretches out said first insulating barrier is provided with through hole, and said bus is connected with said electric cable accessories through through hole.

The beneficial effect of a kind of bus connecting device that employing the utility model provides is: the bus connecting device that the utility model provides, and volume is little after installing, whole structure better and make bus connecting device have higher fail safe through ground hole is set; Through ground hole ground connection, realize that all insulation of bus is tangible, reduced the possibility that electric discharge phenomena take place, shortened creepage distance the useful life of having improved product, improved safety of operators; Junction through electric cable accessories and bus is a semiconductor layer, avoids the breaking-up of discharging and causing mutually because of between bus and electric cable accessories.
