Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, a kind of plug-in type high-pressure wall bushing device, including termination 4, conductive column 1 and cover in conduction
Insulation external member 2 outside column.The external member that insulate is equipped with installation part 3.Installation part uses steel flange.The external member that insulate is exhausted using hard
Edge external member.
The end face of conductive column is located at the inside of the inner hole of insulation external member.Spliced eye 1.1 is equipped in the both ends of the surface of conductive column.
Spliced eye is coaxial with conductive column.The bottom surface of spliced eye is equipped with the connecting screw hole 1.2 coaxial with spliced eye.
Spring touch finger 1.3 is equipped in spliced eye, the medial surface of spliced eye is equipped with annular mounting groove 1.4, spring touch finger installation
In annular mounting groove.
Termination and spliced eye correspond.
Termination includes cable connecting terminals 4.4, the inserting column 4.1 cooperated with spliced eye, is co-axially located at inserting column
It goes up and runs through the connection through-hole 4.2 of inserting column both ends of the surface, the connection bolt 4.5 being plugged in connection through-hole and be electrically connected with inserting column
The connecting column 4.3 connect.
Inserting column is plugged in corresponding spliced eye, and conductive column is electrically connected by spring touch finger with inserting column.Connect bolt
It is connected across connection through-hole and with corresponding connecting screw hole, so that inserting column is fixed on conductive column, avoids inserting column de-
It falls.
Inserting column is an integral molding structure with connecting column.The axis of connecting column and the axis perpendicular of connecting column.Connecting column
It is equipped with external screw hole 4.31.External screw hole is arranged on the end face of connecting column, and external screw hole and connecting column are coaxial.
One end of cable connecting terminals is equipped with connecting screw 4.41, and connecting screw is connected through a screw thread with external screw hole.Electricity
The other end of cable connection terminal is equipped with cable connecting orifice 4.42.
The plug-in type high-pressure wall bushing device of the present embodiment it is specifically used as follows:
First, the connection bolt of termination is unclamped, connection bolt is separated with connecting screw hole, then pulls out inserting column
Out, so that termination be removed；
Second, by cable connecting terminals by being removed on termination；
Then, by the core of power line 5 insertion cable connecting orifice, and by way of crimping by cable connecting terminals with
The core of cable end is connected as one, and cable connecting terminals are electrically connected with the core of electric power thread end；
Followed by connecting screw is connected through a screw thread with external screw hole, so that power line is electrically connected with termination；
Inserting column is plugged in corresponding spliced eye by third, and conductive column is electrically connected by spring touch finger with inserting column；So
Afterwards by tightening connection bolt, connection bolt is connected with corresponding connecting screw hole, so that inserting column is fixed on conductive column,
Inserting column is avoided to fall off.
Since conductive column is electrically connected by spring touch finger with inserting column, it can guarantee the electricity of termination and conductive column in this way
The reliability of connection, and the effect for connecting bolt is fixed on inserting column on conductive column, and inserting column is avoided to fall off, and connects bolt
Coupling mechanism force will not influence the reliability of electrical connection between conductive column and inserting column, thus the plug-in type high-pressure of the present embodiment is through walls
Casing bit is not only easy to operate, and can effectively improve the connection reliability of power line and high-voltage wall bushing, effectively solves
In high-voltage wall bushing in the prior art, since power line is connect with lug plate by screw bolt and nut, once bolt does not have
Locking, then will appear and produce gap between power line and lug plate so that the contact resistance between power line and lug plate increase,
The problem of temperature increases, and power line and lug plate is caused to burn out.
