Description
Technical field
The utility model relates to electric power system job safety measure ground connection installing field, particularly a kind of temporary grounding connector that is suitable for multiple ground stud.
Background technology
Electric equipment overhaul, temporary grounding is indispensable safety measure during operation such as test.At present; The ground stud of the interim ground wires of connection such as all kinds of electric equipments, transmission line generally be divided into anti-error lockset and not with anti-error lockset, and different because of manufacturer with the ground stud of anti-error lockset, specification is also different; The connected mode of corresponding temporary ground wire is also different; Earth connection on the general scene can only with certain ground stud coupling, when earth connection and ground stud do not match, also want on-the-spot interim making connector; So just limit the flexibility of temporary ground wire, influenced electric efficiency of operation.
Summary of the invention
The purpose of the utility model provides a kind of temporary grounding connector that is suitable for multiple ground stud; Overcome the deficiency of prior art; On connector, connecting interface is set, improves the flexibility of temporary ground wire, improve electric efficiency of operation by several kinds of ground stud types of attachment commonly used.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of temporary grounding connector that is suitable for multiple ground stud comprises ground wire link and ground stud link, and said ground wire link is provided with ground connection copper folder; Said ground stud link is respectively equipped with connecting hole one and connecting hole two, and connecting hole one diameter D1 is φ 10-11mm, and connecting hole two diameter D2 are φ 16-17mm.
Said ground stud link is provided with connecting pin, and connecting pin is provided with by iron, nut and lockhole.
The afterbody of said connecting pin is provided with and the supporting lock core of the anti-error lock of electromagnetism, and the wide H of the annular groove on the lock core is 3-3.2mm, and the D3 of lock core diameter is φ 10-11mm.
Compared with prior art; The beneficial effect of the utility model is: through on connector, by several kinds of ground stud types of attachment commonly used connecting interface being set; Improved the flexibility of temporary ground wire greatly; Earth connection can be connected with multiple ground stud easily, significantly improve electric efficiency of operation.

Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Seeing Fig. 1, Fig. 2, is a kind of temporary grounding connector example structure sketch map that is suitable for multiple ground stud of the utility model, and connector body 1 comprises ground wire link and ground stud link, and the ground wire link links to each other with ground connection copper folder 3 through bolt 2; The ground stud link is respectively equipped with connecting hole 1 and connecting hole 25; Connecting hole one 4 diameter D1 are φ 10-11mm; This structure is applicable to the ground stud below the 10mm that is not with anti-error lock; Connecting hole 25 diameter D2 are φ 16-17mm, are applicable to the ground stud of opening up new company, also can be used for other diameters suitable not with the ground stud of anti-error lock.
Also can be provided with connecting pin 10 at the ground stud link; Connecting pin 10 is provided with by iron 6, nut 7 and lockhole 8, and this structure is applicable to the anti-error locking-type ground stud of the excellent special company in Zhuhai, and lockhole 8 diameters are φ 6.5mm; Be used to hang anti-error lock, the screw thread specification on the connecting pin 10 is M14mm * 2mm.
Afterbody at connecting pin 10 also can be provided with and the supporting lock core 9 of the anti-error lock of electromagnetism, and the wide H of the annular groove on the lock core 9 is 3mm, and the D3 of lock core diameter is φ 11mm, and this structure can be fit to the anti-error lock of electromagnetic type of most of specifications.
Because of temporary ground wire 11 all has insulated hull, should design slyness so press from both sides 3 edges at connector body 1 and ground connection copper, can prevent to damage because of friction causes the insulated hull of temporary ground wire 11.
