Abstract
The invention relates to a universal ground wire connector comprising a connecting plate, a latch, a first nut, and a linking plate. The connecting plate and the latch are respectively fixed on the linking plate. A plugging hole where a cylindrical ground wire pile head passes is formed in the connecting plate; and an external thread matching the first nut is formed in the latch and thus the first nut is connected to the latch in a screwing mode, so that locking between the latch and a hole type ground wire pile head is realized after the latch passes through the hole type ground wire pile head. The provided connector has high universality and can be used conveniently; effective connection with two kinds of existing ground wire pile heads can be realized. For the cylindrical ground wire pile head, the cylindrical ground wire pile head can pass through the plugging hole of the connecting plate; and for the hole type ground wire pile head, the latch can pass through the hole type ground wire pile head and then the first nut is screwed to the latch for locking. Moreover, the connector with a simple structure can be manufactured easily and the manufacturing cost is low.

Further, described first nut is wing nut.
Compared to prior art, the invention has the advantages that:
The present invention has versatility, and it is easy to use, can realize effectively being connected with existing two profiles ground wire pile crown, for pillar ground wire pile crown, can by pillar ground wire pile crown through the jack on connecting plate of the present invention, then mounting limit part, with this, the present invention is fixed on pillar ground wire pile crown, for cellular type ground wire pile crown, can by latch of the present invention through cellular type ground wire pile crown, then the first nut to be screwed on latch and to lock, with this, the present invention being fixed on cellular type ground wire pile crown.Therefore, the present invention can improve applicability, the minimizing service ground number of conductors of earth lead, reduces costs spending, solves the incompatible problem of various places five-preventing system; Structure of the present invention is simple in addition, make easily, and cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the front view of one embodiment of the invention.
Fig. 2 is the left view of Fig. 1.
Being labeled as of each parts in accompanying drawing: 1 connecting plate, 11 jacks, 2 latches, 21 first nuts, 22 anti-flakes, 221 lockholes, 3 engagement plates, 31 first engagement plates, 32 second engagement plates, 30 bending sections, 311 first through holes, 321 second through holes, 33 bolts, 34 second nuts, 4 earth leads.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
See Fig. 1.
The universal earth connection point of one embodiment of the invention, comprise connecting plate 1, latch 2, first nut 21 and engagement plate 3, described connecting plate 1 and latch 2 are separately fixed on described engagement plate 3, described connecting plate 1 has the jack 11 passed for pillar ground wire pile crown, described latch 2 is shaped with the external screw thread matched with described first nut 21, for described first nut 21 is screwed in described latch 2, to realize the locking between described latch 2 and cellular type ground wire pile crown after described latch 2 passes cellular type ground wire pile crown.
The universal earth connection point of one embodiment of the invention has versatility, can realize effectively being connected with existing two profiles ground wire pile crown, for pillar ground wire pile crown, can by pillar ground wire pile crown through the jack 11 on connecting plate 1, then mounting limit part, with this, the present invention is fixed on pillar ground wire pile crown, for cellular type ground wire pile crown, can by latch 2 of the present invention through cellular type ground wire pile crown, then the first nut 21 to be screwed on latch and to lock, with this, the present invention being fixed on cellular type ground wire pile crown.Therefore, the present invention can improve applicability, the minimizing service ground number of conductors of earth lead, reduces costs spending, solves the incompatible problem of various places five-preventing system.
See Fig. 2, in the present embodiment, described engagement plate 3 comprises the first engagement plate 31 and the second engagement plate 32, described first engagement plate 31 and the second engagement plate 32 are arranged face to face, and be detachably connected between described first engagement plate 31 and the second engagement plate 32, the middle part of described first engagement plate 31 and the second engagement plate 32 has a bending section 30 outwardly respectively, and described two bending sections 30 enclose the space formed for clamping earth lead 4.Adopt this structure dead earth wire 4, contact area is large, and ampacity is high, good stability, and installs firm, is convenient to disassembling, assembling and replacing earth lead 4.
