As preferred version of the present utility model, on described electric interface, be provided with lead.
As preferred version of the present utility model, on described U-shaped hook, be provided with locating convex block.
As preferred version of the present utility model, described spring stopping means is adjustable nut.
As preferred version of the present utility model, be provided with corresponding lockhole on described depression bar and pedestal.
As preferred version of the present utility model, the vertical vertical height that highly is less than rotating shaft of lockhole on described pedestal.
When a kind of ground connection device for ground wire of the utility model is used, allow ground stud between U-shaped hook and electric interface, by rotating depression bar, make U-shaped hook and electric interface clamp ground stud, when depression bar behind the linkage dead point, jockey forms self-locking, has completed the grounding connection operation of earth connection.In a kind of ground connection device for ground wire of the utility model, spring has guaranteed the reliability connected effectively, makes junction that the requirement of enough contacts dynamic and thermal stability when meeting short circuit be arranged.A kind of ground connection device for ground wire of the utility model, easy to operate, installing/dismounting is quick, safe and reliable, simple in structure.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 is the structural representation of a kind of ground connection device for ground wire of the utility model.
Mark in figure: 1 is pedestal, and 2 is bus-bar, and 3 is the line ball hole, 4 supporting walls, and 5 is electric interface, 6 is rotating shaft, and 7 is depression bar, and 8 is movable axis, and 9 is through hole, and 10 is U-shaped hook, 11 is spring, and 12 is the spring stopping means, and 13 is lead, and 14 is lockhole, and 15 is locating convex block.
Embodiment
Disclosed all features in this specification, or the step in disclosed all methods or process, except mutually exclusive feature and/or step, all can combine by any way.
Disclosed arbitrary feature in this specification, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is,, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
A kind of ground connection device for ground wire of the utility model as shown in Figure 1, comprise pedestal 1, described pedestal 1 one ends are provided with bus-bar 2, offer line ball hole 3 on bus-bar 2, the other end of described pedestal 1 is provided with electric interface 5 and supporting walls 4, described supporting walls 4 is hinged by rotating shaft 6 and depression bar 7 one ends, described depression bar 7 middle parts vertically are connected with movable axis 8, described movable axis 8 two ends are provided with and its axial vertical through hole 9, described through hole 9 is connected with U-shaped hook 10, the bipod of described U-shaped hook 10 has spring 11 through the rear encapsulation of described through hole 9, the end of described U-shaped hook 10 bipods is provided with spring stopping means 12.
As shown in Figure 1 in a kind of ground connection device for ground wire of the utility model, be provided with lead 13 on electric interface 5, be provided with locating convex block on U-shaped hook 10, this structure, pull U-shaped hook 10 at depression bar 7, in the process that electric interface 5 is moved to Earth pile-head, guarantee that lateral displacement does not occur electric interface, prevent from connecting the relative sliding between rear device and Earth pile-head.Spring stopping means 12 is designed to adjusting nut, the deflection of spring 11 can be regulated, thereby can obtain more suitably contact.For preventing the unexpected tripping of depression bar 7, be designed with corresponding lockhole 14 on depression bar 7 and pedestal 1, when depression bar 7 turns to two lockholes coincidences, use five anti-lock two lockholes that pass also to lock.For allowing reliably self-locking of device, on pedestal, the vertical height design of lockhole 14 is vertically highly low than rotating shaft 6.
When a kind of ground connection device for ground wire of the utility model is used as shown in Figure 1, bus-bar 2 connects earth connection by line ball hole 3.Rotate depression bar 7 to vertical with bus-bar 2, make ground stud between U-shaped hook 10 and electric interface 5, U-shaped hook 10 covers hang over the ground stud outside, and locating convex block 15 is near the bolt hole in the ground stud outside, and lead 13 is cut the bolt hole of ground stud inboards.Rotate depression bar 7 to bus-bar 2 directions, make the distance of U-shaped hook 10 and electric interface 5 dwindle gradually.After U-shaped hook, ground stud, electric interface are all fitted, spring 11 starts compression, and spring force acts on movable axis 8 and produces two effects, and one shows as contact, and another shows as depression bar is applied to active force upwards.Be rotated further depression bar 7 and cross critical localisation, i.e. the position of depression bar 7 and U-shaped hook 10 conllinear, the active force that 11 pairs of depression bars 7 of spring apply becomes downwards, and this active force is pressed against on bus-bar 2 depression bar 7, and device forms self-locking.
