Abstract
The utility model provides a vacuum circuit breaker inlet and outlet wiring sheath which is used for protecting wiring parts of an outdoor vacuum circuit breaker and has excellent insulation performance. The vacuum circuit breaker inlet and outlet wiring sheath comprises a sheath. The sheath is divided into a sheath front segment and a sheath rear segment. The sheath front segment and the sheath rear segment are connected in a straight way. The sheath front segment is composed of three cylindrical segments with different diameters. The sheath rear segment is composed of two cuboid segments with different side lengths. The bottom of the sheath is provided with an opening. The two sides of the opening are respectively provided with an outer edge. A plurality of symmetrical close holes are arranged on the outer edges. Plastic buckles are buckled inside the close holes which are symmetrical in pairs. The plastic buckles are adopted to make the sheath closed. A closed state is then formed. The wiring parts of the vacuum circuit breaker are fully wrapped and prevented from being eroded by rain, snow, mist and dust in the natural environment. The damage probability of the vacuum circuit breaker is lowered. The service lifetime of the vacuum circuit breaker is further prolonged.

Summary of the invention
The present invention is directed to the problems referred to above that prior art exists, a kind of protection for outdoor vacuum circuit breaker wiring place is provided, can prevent that sharp objects pierces through, anti-foreign matter, rainwater-proof, have the vacuum circuit-breaker of good insulation property to pass in and out Connection jacket.
For achieving the above object, the utility model is by the following technical solutions:
A kind of vacuum circuit-breaker turnover Connection jacket, comprise sheath, sheath is divided into sheath leading portion and sheath back segment, sheath leading portion and the straight connection of sheath back segment, the sheath leading portion is three sections cylinders that diameter is different, the sheath back segment is two sections cuboids that the length of side is different, sheath leading portion port is provided with the insulator fastening point, sheath back segment port is provided with cable outlet, sheath back segment port is provided with cable outlet, and the sheath bottom surface is provided with an opening, on the sheath of opening part both sides, respectively is provided with outer, some symmetrical lipostomouses are arranged on outer, be buckled with plastic button in symmetrical lipostomous in twos.
Further, plastic button is divided into three parts, and first is homalocephalus, and second portion is the cylinder that diameter is less than the lipostomous diameter, third part is the circular cone that the bottom surface diameter is greater than the lipostomous diameter, and the cylinder of second portion and third part circular cone junction are acute angle bevel.
Further, sheath through the plastic button closure, forms cavity by some symmetrical lipostomouses in twos, can hold vacuum circuit-breaker joint and cable.
Further, sheath through the plastic button closure, forms cavity by some symmetrical lipostomouses in twos, and the sheath leading portion inner surface contour of formation and vacuum circuit-breaker joint surface profile are identical.
Further, sheath through the plastic button closure, forms cavity by some symmetrical lipostomouses in twos, and the sheath back segment inner surface contour of formation and cable surface profile are identical.
Further, the profile of outer conforms to the sheath profile.
The beneficial effects of the utility model are: the one, by plastic button by the sheath closure, form airtight state, vacuum circuit-breaker wiring place is fully wrapped up, avoid standing the erosion of rain, snow, mist, dust in natural environment, reduce the damage probability of vacuum circuit-breaker, improve useful life; The 2nd, the shape of the sheath actual shape of vacuum circuit-breaker wiring place of more fitting, than the Vintage Product actual product shape of more fitting, also saved raw material; The 3rd, the design of opening outer, be convenient to fixing and sealing, can also improve the water proofing property of sheath.
