Abstract
The utility model discloses a grounding connector used for a cable branch box, which comprises a connector body. A first terminal of the connector body is provided with screw holes which can be connected with T-shaped cable splices in the cable branch box. A second terminal of the connector body is connected with an upright post which can be grounded to be connected. Adopting the technical proposal, the utility model can cause maintainers to need not to hang grounding wires on an outdoor pole, but only need to connect the connector with the incoming cable position of the cable branch box so as to hang the grounding wires on the connector, thereby not only meeting the safety condition of repair and maintenance, but also needing not to disuse adjacent lines erected by previous or the same pole, so as to reduce the power failure range.
Description
Technical field
The utility model relates to a kind of being used for earth lead is connected to grounding connector in the cable branch box.
Background technology
Along with process of urbanization, cable with its distinctive occupation of land less, power supply is reliable, the electric shock possibility is little, easy to maintenance etc., and advantage is used in the city in a large number, and cable is accepted and distributed the cable branch box of electric energy to have good barrier propterty, also be used in the urban distribution network in a large number.
Usually, overhaul and safeguard that outdoor vacuum switch on the bar when cable branch box that cable inserts, needs to satisfy three safety conditions:
One, the switch that is connected with cable branch box need cut out;
Two, and on the circuit that cable branch box is connected a tangible plug-in strip cutoff circuit to be arranged;
Three, with hang on the cable branch box inlet wire cable line earth connection (or the ground connection plug-in strip that closes) as the protection.
Preceding two safety conditions are all realized easily, but the 3rd safety condition can't be implemented because of outdoor vacuum switching device problem.Specifically be because step on distance that the bar operating personnel will hang earth connection place and outdoor vacuum switch isolation plug-in strip fixed contact place less than safe distance 700mm, so can not on the inlet wire cable line, hang the 10kV earth connection.Thereby the adjacent lines that makes the maintenance cable branch box need stop using upper level and joint use has enlarged the power failure scope, has caused inconvenience for production and electricity consumption.
Summary of the invention
The utility model provides a kind of grounding connector at above-mentioned deficiency, this connector can be connected with the inlet wire cable place of cable branch box, thereby can on this connector, hang earth connection, both satisfied the safety condition of repair and maintenance, the adjacent lines that can stop using upper level and joint use has reduced the power failure scope again.
The technical solution of the utility model is achieved in that a kind of grounding connector that is used for cable branch box, include connector body, first end at described connector body is provided with the screw that can be connected with the T type cable joint in the cable branch box, but is connected with the column that ground connection connects at the second end of connector body.
As preferably, described column is a cylinder.
As preferably, described column is a prism.
As preferably, described column is a hexagonal prism.
As preferably, described column also is connected with one can make connector body be connected to hexagonal prism on the T type cable joint.
As preferably, the cross-sectional area of described hexagonal prism is less than the cross-sectional area of column.
As preferably, the cross-sectional area of described column is less than the cross-sectional area of connector body.
Owing to adopted technique scheme, the utility model can so that the maintainer out of doors bar get on to hang earth connection, and only need connector is connected with the inlet wire cable place of cable branch box, thereby on this connector, hang earth connection, both satisfied the safety condition of repair and maintenance, the adjacent lines that can stop using upper level and joint use has reduced the power failure scope again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is a grounding connector of the present utility model schematic diagram when screwing in T type cable joint.
Among the figure: 1, connector body; 2, screw; 3, first end; 4, the second end; 5, column; 6, hexagonal prism; 7, T type cable joint; 8, stud.
Embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1 and Figure 2, according to a kind of grounding connector that is used for cable branch box of the present utility model, include connector body 1, connector body 1 has cylindrical shape, first end 3 at described connector body 1 is provided with the screw 2 that can be connected with the T type cable joint 7 in the cable branch box, but is connected with the column 5 that ground connection connects at the second end 4 of connector body 1.
Described column 5 can be the shape of cylinder or prism, and for the chuck with earth lead has the contact area of a maximum, as optimal design, column 5 is designed to the shape of hexagonal prism.
As Fig. 2, shown in Figure 3, in order to make on the stud 8 in the T type that the is connected to cable joint 7 that connector body 1 can be fastening, described column 5 also is connected with one can make connector body 1 be connected to hexagonal prism 6 on the T type cable joint 7, during installation, connector body 1 is screwed in T type cable joint 7, thereby and make connector body 1 fastening being connected on the stud 8 with spanner rotation hexagonal prism 6.
Clear and definite for each parts is divided the work, accurate positioning, the cross-sectional area of described hexagonal prism 6 is less than the cross-sectional area of column 5, and the cross-sectional area of described column 5 is less than the cross-sectional area of connector body 1.Thus, when the chuck of earth lead is clamped column 5, connector body 1 can be do not slided to, column 5 can not be hampered when connector body 1 being screwed in T type cable joint 7 with spanner rotation hexagonal prism 6.
