3, flat copper and water conservancy diversion reinforcement welding complex process in construction.
Along with the development of technology, there is again the spuious terminal structure of a kind of new-type flush type in the later stage, as shown in figure.The spuious terminal structure of flush type comprises copper material terminal head 1 ' and steel matter terminal tail 2 ', terminal head 1 ' and terminal tail 2 ' are welded to form by adopting heat release, integral device is provided during this spuious terminal structure supply of material, its copper tip head is cast copper, screwed hole is provided with in terminal head, because the screw thread of its external connection screwed hole is all in copper tip, in order to ensure the thrust of connection bolt, screwed hole diameter must reach 16mm, just there is enough intensity, which increases diameter and the length of copper tip.In this terminal structure, be provided with small-sized dust cap 3 ', this small-sized dust cap 3 ' is buckled in the place of the opening of screwed hole, and therefore this technology exists following drawback:
1, terminal copper consumption is larger;
2, external wiring terminal cannot use GB binding post;
3, because being cast copper and exothermic weld, more crisp, be hit easy fracture and stolen;
4, small-sized dust cap be directly be buckled in screwed hole opening above, volume is smaller, easily drops and not easily opens and uses.
Utility model content
For reaching above object, the technical scheme that the utility model is taked is: the spuious terminal structure of a kind of compound flush type, and comprise terminal head, terminal base and terminal tail, described terminal head is welded on the upper end of terminal base, and described terminal tail is welded on the lower end of terminal base; Screwed hole is provided with, described screwed hole penetrating terminal head extend to terminal base inside from top to down in terminal head; Described terminal head, terminal base, terminal tail are cylindrical respectively, and form an entirety.
On the basis of technique scheme, the utility model also comprises dust cap, and described dust cap edge is concordant with the edge of terminal head, and the bottom surface of dust cap is provided with inserted link; Described inserted link is arranged in screwed hole, and inserted link is provided with the external screw thread closed with described corresponding threaded holes.
On the basis of technique scheme, described dust cap is that PP plastic material is made.
On the basis of technique scheme, in the middle of the end face of described dust cap, be provided with groove.
On the basis of technique scheme, described terminal head is T3 copper material, diameter is 35mm, is highly 10mm.
On the basis of technique scheme, described terminal base is Q235A steel matter, and diameter is 35mm, is highly 25mm.
On the basis of technique scheme, described terminal tail is Q235A steel matter, and diameter is 20mm, is highly 140mm.
On the basis of technique scheme, the diameter of described screwed hole is 12mm.
On the basis of technique scheme, described terminal head and terminal base, friction pressure Welding Structure between terminal base and terminal tail, is all adopted to form.
The beneficial effects of the utility model are:
1, terminal head is welded on the upper end of terminal base, and terminal tail is welded on the lower end of terminal base; The spuious terminal of compound flush type of this structure composition, can greatly reduce copper consumption, reduce the cost of enterprise, and because adopting friction pressure welding more firm, being not easily hit and also not easily knocking off, serving antitheft effect;
2, in terminal head, screwed hole is provided with, screwed hole penetrating terminal head extend to terminal base inside from top to down; Ensureing that under the prerequisite that bonding strength increases, more difficult drop-off, enhances connection reliability;
3, at the dust cap that terminal head upper end is provided with, dust cap edge is concordant with the edge of terminal head, and the bottom surface of dust cap is provided with inserted link; Inserted link is arranged in screwed hole, and inserted link is provided with the external screw thread closed with corresponding threaded holes, also protects screwed hole like this and is without prejudice, and more firmly not easily drop while the terminal head that protection is whole.
