Abstract
The utility model discloses a universal ground wire connector, which comprises ground wire connection holes and matched bolts and nuts, a ground stud connection hole, a ground stud connection screw and a matched nut. The universal ground wire connector also comprises a cylindrical base plate; one side of the cylindrical base plate is provided with a conducting plate; the ground wire connection holes and the ground stud connection hole are located on the conducting plate; and the other side of the cylindrical base plate is provided with the ground stud connection screw in the same coaxial line and the matched nut. The universal ground wire connector has the advantages that the structure is simple, the manufacturing is convenient, the cost is low and the like. When a ground wire needs to be grounded in the electrical equipment maintenance process, the universal ground wire connector disclosed by the utility model can enable the ground wire to be connected with the ground stud manufactured by different manufacturers so as to improve the work efficiency.
Description
Technical field
The utility model relates to a kind of earth connection cardan.
Background technology
Power supply unit when maintenance, in order to prevent electric shock accidents, need to carry out ground connection to equipment, ground connection side's method is: equipment is connected with ground stud by earth connection, needs to be connected by earth connection point between earth connection and ground stud.Due to present five anti-product disunities, the ground stud of each manufacturer production is different from the ground wire connected mode, the connecting hole that passes through self that has connects earth connection point, and the screw rod that passes through self that has connects earth connection point, and different manufacturer production connecting screw rod specification out is different.Therefore, the earth connection point that different ground studs mates is also different, can not be general.The earth connection of transformer station configures according to general maintenance scale.When transformer station overhauls on a large scale, when the earth connection that need to install is more, will allocate earth connection from other transformer station.But because the earth connection point at each station is different, can not match each other, need the replacement of ground wire joint to use, increase workload, also increase interruption duration.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of earth connection cardan, and it has the characteristics such as simple in structure, easy to make, that cost is low.When needing ground connection in the electric equipment maintenance process, use it can realize that ground wire is connected with any different manufacturers grown place ground stud, increases work efficiency.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Be provided with ground wire connecting hole and suitable bolt and nut, ground stud connecting hole and ground stud connecting screw rod and suitable nut.
The utility model further improves and is:
It comprises cylindrical backing plate, is provided with conducting strip in a side of cylindrical backing plate, and ground wire connecting hole and ground stud connecting hole are positioned on conducting strip, is provided with and the ground stud connecting screw rod of its coaxial line and the nut suitable with it at the opposite side of cylindrical backing plate.
End at the ground stud connecting screw rod is provided with lockhole, and described lockhole is positioned on the brace that the end of ground stud connecting screw rod is provided with.
Cylindrical backing plate, conducting strip, ground stud connecting screw rod and brace are copper material, and by being welded to connect.
The beneficial effect that adopts technique scheme to produce is: this earth connection cardan is provided with ground wire connecting hole and suitable bolt and nut, ground stud connecting hole and ground stud connecting screw rod and suitable nut.Connecting hole or connecting screw rod that no matter ground stud is provided with by self, no matter specification is big or small, all can mate with this joint and be connected, be connected with ground wire by the ground wire connecting hole of this joint and suitable bolt and nut, can complete being connected of ground wire and ground stud, this earth connection cardan can make ground wire be connected with any different manufacturers grown place ground stud, has solved the earth terminal mismatch problem, has improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, ground wire connecting hole; 2, ground stud connecting hole; 3, ground stud connecting screw rod; 4, cylindrical backing plate; 5, conducting strip; 6, lockhole; 7, brace.
Embodiment
By embodiment shown in Figure 1 as can be known:
It comprises cylindrical backing plate 4, a side at cylindrical backing plate 4 is provided with conducting strip 5, ground wire connecting hole 1 and ground stud connecting hole 2 are positioned on conducting strip 5, are provided with and the ground stud connecting screw rod 3 of its coaxial line and the nut suitable with it at the opposite side of cylindrical backing plate.The ground stud connecting hole should be able to be suitable with the maximum connecting screw rod that ground stud arranges, the ground stud connecting screw rod should be able to be suitable with the minimum connecting hole that ground stud arranges, the purpose that is connected with the ground stud of any different manufacturers production by this joint to reach ground wire.
Be provided with lockhole 6 in the end of ground stud connecting screw rod 3, on the brace 7 that the end that described lockhole 6 is positioned at ground stud connecting screw rod 3 is provided with.
Using method:
Ground wire is connected with cardan by the ground wire connecting hole of cardan and suitable bolt and nut, screw rod or the connecting hole of the ground stud connecting hole by cardan or ground stud connecting screw rod and suitable nut and ground stud self are connected with ground stud, ground wire is connected with the ground stud of any different manufacturers production, thereby solved the earth terminal mismatch problem, improved operating efficiency.
