Abstract

The utility model relates to a grounding wire device of a cable branch box. The grounding wire device is characterized by comprising a connecting rod (1), wherein one end of the connecting rod (1) is fixedly connected with one end of a connecting pipe, and the other end of the connecting pipe is shaped as a funnel. The test shows that the grounding wire device of the cable branch box has good using effect and can be grounded firmly and reliably. After the grounding wire device is hung on a cable branch box of a 10KV power distribution line, the problem of reliably hanging and disassembling a grounding wire when the cable branch box is powered-off is effectively solved, the area of contact between the grounding device and equipment is increased, the grounding wire device is ensured to be grounded firmly and reliably, and the life safety of the operation and maintenance personnel is effectively guaranteed.

Description

The cable branch box grounding wire device
Technical field
The utility model 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.
The utility model content
The purpose of this utility model 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 on connecting rod, and nut also is installed on this connecting rod.
Through probationary certificate, adopt cable branch box grounding wire mounting of the present utility model postpone, result of use is good, and ground connection is solid and reliable.Hang grounding wire mounting postpone of the present utility model through dress on 10KV distribution line cable branch box, 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 utility model;
Accompanying drawing 2 is right view of the present utility model.
Embodiment
As shown in Figure 1, 2, the utility model is a kind of cable branch box grounding wire device, comprise connecting rod 1, 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, can be specifically 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 for being sleeved on the pipe on inner tube 4, is provided with screw thread, and on this connecting rod 1, nut 2 is installed also on connecting rod 1 in addition.
Using method of the present utility model is: the nut 2 that during use, the terminal of earth connection is articulated on connecting rod 1 is other, rotating nut 2 makes its clamping, then with insulating bar, the leading portion 5 of inner tube in tube connector 4 is inserted on earth terminal in cable branch box, thereby both are fully contacted.
