Abstract

The invention relates to a ground connection wire device of a cable branch box. The ground connection wire device is characterized by comprising a connection rod (1), one end of the connection rod (1) is fixedly connected with one end of a connection tube, and the other end of the connection tube is in a shape of a funnel. A test proves that the ground connection wire device of the cable branch box is good in using effect and firm and reliable in ground connection. After the ground connection wire device is hanged on a 10KV distributing line cable branch box, a problem that a ground connection wire of the cable branch box can be hung and disassembled when power is cut is solved, particularly a contact area between a grounding device and equipment can be increased, ground connection is guaranteed to be firm and reliable, and life safety of a transportation and checking worker can be effectively guaranteed.

Description

The cable branch box grounding wire device
Technical field
The present invention relates to a kind of cable branch box grounding wire device.
Background technology
When the cable branch line failure, need power failure actuating cable feeder pillar to overhaul, for example common 10KV cable branch box.In order to ensure the safety of the person and equipment, must be at the in-built hanging earthing conductor of cable branch box during maintenance, this measure concerns fortune inspection personnel's personal safety.But existing earth connection generally is not suitable for the dress of cable branch box to be hung, and it is unreliable to cause during use connecting, thereby brings great threat to maintainer's personal safety when maintenance.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, reliable cable branch box grounding wire device of connection.
A kind of cable branch box grounding wire device, its special feature is: comprise connecting rod, an end of this connecting rod is fixedly connected with an end of a tube connector and the other end of this tube connector is funnel-form.
Wherein the two ends of tube connector are funnel-form.
Wherein tube connector is comprised of inner and outer tubes, and inner tube is comprised of the leading portion that is connected, stage casing and back segment, and this leading portion and back segment are the triangular cone of hollow, and leading portion is connected the tip and is connected with the two ends in stage casing respectively with back segment, and the stage casing is pipe in addition.
Its middle external tube is pipe.
Wherein be provided with screw thread at connecting rod, and on this connecting rod, nut be installed also.
Through probationary certificate, adopt cable branch box grounding wire mounting of the present invention postpone, result of use is good, and ground connection is solid and reliable.Through hanging grounding wire mounting postpone of the present invention at 10KV distribution line cable branch box dress, effectively solved when cable branch box has a power failure reliably hang, the problem of dismounting ground wire, especially increased the contact area of earthing device and equipment, guarantee that ground connection is solid and reliable, effectively ensured fortune inspection personnel's life security.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention;
Accompanying drawing 2 is right view of the present invention.
Embodiment
As shown in Figure 1, 2, the present invention is a kind of cable branch box grounding wire device, comprises connecting rod 1, and an end of this connecting rod 1 is fixedly connected with an end of a tube connector and the other end of this tube connector is funnel-form, specifically can be that the two ends of tube connector are funnel-form.
Wherein tube connector is comprised of inner tube 4 and outer tube 3, and inner tube 4 is comprised of the leading portion 5 that is connected, stage casing 6 and back segment, this leading portion 5 and back segment are the triangular cone of hollow, and leading portion 5 is connected the tip and is connected with the two ends in stage casing 6 respectively with back segment, and stage casing 6 is pipe in addition.Outer tube 3 is provided with screw thread at connecting rod 1, and on this connecting rod 1 nut 2 is installed also for being sleeved on the pipe on the inner tube 4 in addition.
Using method of the present invention is: the nut 2 that during use the terminal of earth connection is articulated on the connecting rod 1 is other, rotating nut 2 makes its clamping, then with insulating bar the leading portion 5 of inner tube in the tube connector 4 is inserted on the earth terminal in the cable branch box, thereby both are fully contacted.
