The zero line terminal comprises a zero line terminal seat and a line fixing screw. The zero line terminal seat comprises an insulating casing and a conductive core which is arranged in the insulating casing. One end of the conductive core is provided with an inner screw hole which is matched with the screw thread of the line fixing screw. The other end of the conductive core is raised and is provided with a fixing screw which is coaxial with the inner screw hole. The capacitor casing body is provided with a connecting hole which is in screw thread connection with the fixing screw. The end face, which is corresponding to the capacitor casing body, of the insulation casing is provided with an annular groove. An O type sealing ring is arranged in the annular groove. The fixing screw is located in the central region of the O type sealing ring. The connection structure provided by the utility model has the advantages of reasonable structural design and convenient and stable connection, and effectively ensures the sealing performance of the capacitor casing.
Description
Technical field
The utility model relates to a kind of power capacitor, specifically refers to a kind of syndeton of power capacitor zero terminal.
Background technology
On the shell of existing power capacitor, be generally all provided with zero terminal, for electric power zero line, connect.Existing zero terminal is to be all generally weldingly fixed on shell, welding cost is high, and the temperature rise meeting that causes of welding makes casing deformation, in addition, the position being welded to connect gets rusty easily and causes shell seal to decline, and has affected the normal operation of the capacitor body in capacitor case.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and provide, a kind of structure connects simply, switching performance is reliable and the syndeton of the good power capacitor zero terminal of closure.
For achieving the above object, the technical solution of the utility model is to include capacitor casing and zero terminal, described zero terminal includes zero line side stroma and solidus screw, described zero line side stroma includes insulation crust and is arranged at the conductive core in insulation crust, one end of described conductive core is provided with the inner bolt hole coordinating with solidus screw thread, the other end projection of described conductive core is provided with the hold-down screw coaxial with inner bolt hole, described capacitor casing is provided with the connecting hole being threaded with hold-down screw, on the end face of the described corresponding capacitor casing of insulation crust, be provided with annular groove, in this annular groove, be provided with O RunddichtringO, described hold-down screw is positioned at the central area of this O RunddichtringO.
By this setting, adopt above-mentioned screw connection structure, and seal in conjunction with O RunddichtringO, not only easy to connect, and effective guarantee the closure of capacitor casing.
Further arrange be described zero line side stroma insulation crust be provided with outer-hexagonal edge.Because capacitor case general thickness is thinner, after zero line side stroma screw thread is fixed on capacitor case, if have and firmly twist solidus screw, be easy to make zero line side stroma to rotate together, the inefficacy that causes being threaded, makes zero line side stroma dally at capacitor case, by this setting, in line pressing bolt, twist while connecing, can adopt die nut to be first fixed on the outer-hexagonal edge of zero line side stroma, the stability that effective guarantee zero line side stroma is connected with capacitor case.
Further arranging is that the periphery lateral protrusions of the described relative connecting hole of capacitor casing is provided with annular nib, this annular nib be embedded in annular groove and with O RunddichtringO location secure fit.By this setting, ensured the sealing effectiveness of O RunddichtringO.
Further arranging is that the inner side of described capacitor casing is provided with the flat shim being fixedly connected with hold-down screw, and between this flat shim and the inwall of capacitor casing, crimping is fixed with insulating washer.By this setting, make capacitor casing and zero line side stroma secure and reliable connection.
Eventually the above, the utility model has the advantages that reasonable in design, and stable connection is convenient, and effective guarantee the closure of capacitor case.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
