Abstract
The utility model discloses a new inner earthing wire of cable branch box which consists of an earthing screw rod 2 which is connected with tail of the screw rod of the wiring terminal by head screw 1, two nuts that are connected with tail crew thread 9, flat washers, a spring washer and an insulating operation screw 15. One end of an wiring ear 5 of a soft ground wire 13 is folded between the flat washers. The other end of the soft ground wire is provided with an outside ground wire ear 14 which can be grounded on floor to be firmly earthed. One can loose the two nuts to disconnect the ground wire. The utility model has the advantages of safe operation, maintenance and construction, needless of alter the box body and the cable head, easy, convenient and safe to be assembled and disassembled.
Description
Earth connection relates to earth connection in a kind of cable branch box in the cable branch box of the present utility model.
Is not have earth connection supporting with it in the cable branch box of 10KV electric power system at present, has directly influenced the fail safe of electric power system, lacked the safety guarantee of operation, maintenance, construction.
The purpose of this utility model provides a kind of safety guarantee with operation, maintenance, construction, does not need casing and cable end are changed, and installs and remove earth connection in all very simple, convenient, the safe cable branch box.
Earth connection includes the grounding screw rod of ground connection binding post screw rod tail thread connection in its head and the cable branch box in the cable branch box of the present utility model, and two nuts, plain washer, spring washer, the insulating bar that connect with the grounding screw rod tailing screw flight, in the middle of two plain washers, accompany a terminated line ear of hag line, the other end of hag line has an external ground wire ear, and described insulating bar is a tapped pullover joystick that connects with insulating bar.
Because the grounding screw rod head of earth connection is directly and after the binding post screw rod tail thread connection in the cable branch box of the present utility model, two nuts of its tailing screw flight connection are tight a terminated line ear clip of plain washer, spring washer, hag line then, the external ground wire ear of the other end of hag line is connected on and gets final product firm ground connection on the ground plate, when tearing ground wire open two nuts are unclamped and get final product, the safety guarantee that has operation, maintenance, construction behind the earth connection, do not need casing and cable end are changed, and install and remove all very simple, convenient, safety.
Below in conjunction with accompanying drawing earth connection in the cable branch box of the present utility model is described in more detail.
Fig. 1 is the structure cutaway view of earth connection in the cable branch box of the present utility model.
By shown in Figure 1, earth connection includes the grounding screw rod 2 of ground connection binding post screw rod tail thread connection in its head threads 1 and the cable branch box in the cable branch box of the present utility model, and two nuts 3 that connect with grounding screw rod tailing screw flight 9 and 8, plain washer 4 and 6, spring washer 7, insulating bar 15, in the middle of plain washer 4 and 6, accompany a terminated line ear 5 of hag line 13, the other end of hag line has an external ground wire ear 14, and described insulating bar 15 is joysticks that pullover 10 and insulating bar 12 of a band internal thread 11 connects.
Because the grounding screw rod head threads 1 of earth connection is directly and after the binding post screw rod tail thread connection in the cable branch box, two nuts 3 and 8 of connecting of its tailing screw flight 9 are a terminated line ear 5 clampings of plain washer 4 and 6, spring washer 7, hag line 13 then, the external ground wire ear 14 of the other end of hag line 13 is connected on and gets final product firm ground connection on the ground plate, when tearing ground wire open two nuts 3 and 8 are unclamped and get final product, the safety guarantee that has operation, maintenance, construction behind the earth connection, do not need casing and cable end are changed, and install and remove all very simple, convenient, safety.
