Description
Technical field
The present invention relates to low-voltage meter box field, relate in particular to a kind of low-voltage meter box Special grounding wire.
Background technology
Earth connection is protection maintainer's key safety barrier, is the lifeline of electrical employee.Earth connection is for ground connection or ground connection and short circuit object, and installing earth connection is important technical measures for electric safety, with being manually connected to the clear and definite no-voltage of experience, obtains the device on electric equipment.Its Main Function is to prevent unexpected incoming call, power transmission, the injury of induced voltage to human body.New < < safety > > 3.4.1 bar is clearly stipulated: after the clear and definite no-voltage of circuit experience, should install immediately earth connection three-phase shortcircuit (DC line the two poles of the earth earth connection is direct ground connection respectively).Each end of each shift's job site and likely power transmission are all wanted electrical verification, installation earth connection to the branch line (comprising user) of dead line job site.But in real work; because being used frequently and operate, earth connection seems simple; easily make people produce decline in alertness; its importance is also often ignored by people; often there is incorrect service condition or because the shortcoming of earth connection itself; so that reduce the safeguard protection effect that has even sometimes lost earth connection, must cause enough attention, and do not have simple in structure, the easy to operate and safe and reliable Special grounding wire for low-voltage meter box in the market.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, a kind of simple in structure, easy to operate, safe and reliable low-voltage meter box Special grounding wire is provided.
Object of the present invention realizes by following technical solution:
A kind of low-voltage meter box Special grounding wire, for the busbar of table case and ground are connected, comprise earth connection, it is characterized in that: also comprise conducting electricity being connected to the joint of earth connection end, described joint has and the nut that spins that screw rod coordinates that exposes on busbar, and the nut that spins is electric conducting material.
Further, described joint comprises the nut that spins, action bars and locking nut, one end of nut spins described in described action bars is fixed on, it has the spiro rod section that can coordinate with described locking nut and the lever piece coordinating with specific purpose tool, on described earth connection, be provided with the metallic conduction ring being set on spiro rod section, described locking nut is set in and on spiro rod section, locks described metallic conduction ring.
Further, described action bars by its spiro rod section with described in the spin screw of nut one end be threaded, on the described nut that spins, be provided with the positioning screw hole being communicated with its center screw, in described positioning screw hole, be equipped with for locking the bolt of described spiro rod section.
Further, the cross section of described lever piece is non-circular.
Further, the cross section of described lever piece is regular polygon.
Further, on described busbar, expose the screw rod that screw rod is binding post bolt.
Further, the nut that spins described in is microscler nut.
The present invention has following beneficial effect:
Earth connection is connected with the screw flight that exposes carrying on busbar by having the joint of the nut that spins, and has simple in structure, handiness, an advantage such as connection is reliable, conductive effect is good; Joint comprises the nut that spins, action bars and locking nut, the lever piece cross section of action bars is non-circular, can coordinate with electric wrench and operate easily the nut rotation that spins, the nut that makes to spin is tightened on exposing on screw rod or from exposing screw rod of busbar and exits, thereby reduction labour intensity, improves the reliability connecting; The spiro rod section of action bars can with the center screw rapid abutting joint of the nut that spins, and can lock the metallic conduction ring on earth connection with locking nut, make joint have simple in structure, easy to operate, connect the advantages such as reliable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is use state diagram of the present invention.
Embodiment
Shown in Fig. 1, a kind of low-voltage meter box Special grounding wire, comprise that earth connection 9 and conduction are connected to the joint of earth connection 9 ends, joint comprises the microscler nut 4 that spins, action bars 6 and locking nut 7, action bars 6 is comprised of the spiro rod section 61 that can coordinate with locking nut 7 and the lever piece 62 coordinating with specific purpose tool, on earth connection 9, be provided with the metallic conduction ring 8 being set on spiro rod section 61, locking nut 7 is set in and on spiro rod section 61, locks metallic conduction ring 8, action bars 6 is threaded with the screw of nut 4 one end that spin by its spiro rod section 61, spin on nut 4 and be provided with the positioning screw hole 41 being communicated with its center screw, in positioning screw hole 41, be equipped with the bolt 5 for tie down screw section 61, the cross section of lever piece 62 is regular hexagon, the cross-sectional profile of nut 4 of spinning is regular hexagon.
Concrete connected mode is: on busbar 1, be provided with binding post bolt 2, bolt 2 is locked on busbar 1 by nut 3, when needs ground connection, the lever piece of joint 62 is connected with electric wrench, the nut 4 that spins is aimed to the screw rod of bolt 2, start electric wrench the nut 4 that spins is tightened on the screw rod of bolt 2, so can complete the connection of earth connection.
The above, be only preferred embodiment of the present invention, therefore can not limit scope of the invention process with this, the equivalence of doing according to the present patent application the scope of the claims and description changes and modifies, and all should still remain within the scope of the patent.
