Description
Technical field
The invention belongs to electric power measuring device technical field, and in particular to a kind of cable connector with double shield function.
Background technology
The high pressure pilot project such as the dielectric loss of power transformer and insulaion resistance is to judge electric power transformer insulated state
A kind of effective means, be that power transformer is joined and the main project of the experiment such as preventative.Dielectric loss, insulaion resistance
Test requirements document etc. high pressure detection project determines that test loop need to have double shield function.Hi-pot test line on the market at present
Double shield function can be accomplished, but cable connector can not accomplish double shield function, the cored wire of Hi-pot test line and interior can only be connect
Shielding line, external shield line then need to be grounded with single joint.
During Hi-pot test line use, there is pressure difference in cored wire itself, internal shield, external shielding layer.Using without double shield
During the cable connector of function, because external shield line individually peels away ground connection, band high pressure between external shielding layer and internal shield so that
The cable connector that human hand is affectedly bashful unparalleled function of shielding plugs high-tension apparatus abnormal condition to be accessed.
The content of the invention
The purpose of the present invention is aiming at the deficiencies in the prior art, there is provided a kind of cable connector with double shield function,
The cored wire, internal shield and external shielding layer of Hi-pot test line can be made to be arranged on same cable connector.
The present invention includes lock-on connection, ground connection cylinder, insulating cylinder, inner shield cylinder, core wire tube.
Described lock-on connection uses insulating materials, for holding the lead of access, afterbody and the ground connection cylinder of lock-on connection tightly
Threaded one end connection；
Described ground connection cylinder uses metal material, the external shielding layer of the lead for connecting access, is grounded the other end of cylinder
It is connected with the threaded one end of insulating cylinder；
Described inner shield cylinder uses metal material, for connect access lead internal shield, inner shield cylinder with absolutely
The other end of edge cylinder is connected；
Described core wire tube uses metal material, the cored wire of the lead for connecting access；Core wire tube is arranged on inner shield
In cylinder, and the insulating sleeve by being set in outside core wire tube is realized and insulated between core wire tube and inner shield cylinder；Described core wire tube
Both ends ecto-entad offers the cored wire blind hole for fixing cored wire respectively, and blind for fixing the contact pin waiting for plugging standby contact pin
Hole.
It is grounded cylinder in the present invention to connect by insulating cylinder insulation with inner shield cylinder, inner shield cylinder passes through insulation sleeve with core wire tube
Cylinder insulation connection, forms stable stepped annexation.In wiring, by the external shielding layer of Hi-pot test line and ground connection inner cylinder
Conducting connection, internal shield turns on connection with inner shield cylinder, cored wire turns on connection with core wire tube.So it is achieved that Hi-pot test
Cored wire, internal shield and the external shielding layer of line are arranged on same cable connector.The present invention damages the medium of power transformer
In the high pressure pilot project such as consumption and insulaion resistance, people can contact joint during plug and use, more securely and reliably, connect
Line is more convenient.
