Description
Technical field
The utility model relates to a kind of fuse, and more particularly, it relates to a kind of fuse switch.
Background technology
At present, fuse on market is primarily of insulator, the upper contact head and the lower contact that are arranged on insulator two ends are formed, fusion tube is provided with between upper contact head and lower contact, fusion tube one end and lower contact hinged, the other end is placed in pull hook, pull hook is arranged on connecting plate that upper contact head is fixedly connected with, connecting plate and pull hook are assembled into the separate part of fuse, general pull hook is welded on connecting plate, therefore, a welder is needed to weld it when assembling fuse, cost of labor is high, and human weld, efficiency is low, stability is determined according to the consummate degree of welder's technical ability, so stability is difficult to ensure.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide the fuse switch that a kind of cost is low and production efficiency is high.
For achieving the above object, the utility model provides following technical scheme:
A kind of fuse switch, comprise fuse, tell fuse primarily of insulator, the upper contact head being arranged on insulator one end, described upper contact head is fixedly connected with connecting plate, described connecting plate is connected with pull hook, and described pull hook and connecting plate pass through rivet.
The utility model is set to further: the position that described pull hook is connected with connecting plate strikes out tabular and forms link, described link is provided with connecting through hole, on described connecting plate, the position of corresponding connecting through hole is provided with installation through hole, and rivet runs through connecting through hole and installs through hole realization riveted joint.
By adopting technique scheme, pull hook through punching press to be formed after link directly by rivet at connecting plate, easy to connect, stable, efficiency is high, does not need human weld, reduces cost of labor and welding is more attractive in appearance relatively.
The utility model is set to further: end face and the connecting plate of the relative connecting plate of described link are fitted.
By adopting technique scheme, link and connecting plate fits, the contact area of both increases, lessly rock, the stability that further increase link is connected with connecting plate.
The utility model is set to further: rivet and connecting through hole and install the equal interference fit of through hole.
By adopting technique scheme, rivet and connecting through hole and after through hole interference fit is installed, the stablizing of the increase pull hook of a step and connecting plate, firm again in the riveting process of rivet.
The utility model is set to further: the thickness of described link is 2/1 to three/3rds of pull hook diameter.
By adopting technique scheme, the link that punching press is formed plays thickness at 2/1 to three/3rds of pull hook diameter, ensures hardness and the useful life of link, makes its not easy fracture.
The utility model is set to further: rivet is provided with two, with the connecting through hole of rivets with install through hole and be equipped with two.
By adopting technique scheme, the quantity of rivet is two, when ensureing the stability that connecting plate is connected with pull hook, avoiding waste and increasing unnecessary cost.
The utility model is set to further: two rivets distribute along the length direction of link.
By adopting technique scheme, the link broadband that punching press is formed is less relative to its length, and two rivets distribute along the length direction of link, active force disperse evenly.
The utility model is set to further: rivet is riveted on pull hook and connecting plate with after metal-to-metal adhesive.
By adopting technique scheme, with metal-to-metal adhesive rivet and be bonded on pull hook and connecting plate, stable, fastness is higher.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model fuse switch embodiment;
Fig. 2 is the pull hook schematic diagram 1 of the utility model fuse switch embodiment;
Fig. 3 is the pull hook schematic diagram 2 of the utility model fuse switch embodiment.
In figure: 1, fuse; 11, insulator; 12, upper contact head; 2, connecting plate; 21, through hole is installed; 3, pull hook; 31, link; 311, connecting through hole; 4, rivet.
Embodiment
Referring to figs. 1 through Fig. 3, the utility model fuse switch embodiment is described further.
A kind of fuse switch, comprise fuse 1, tell fuse 1 primarily of insulator 11, the upper contact head 12 being arranged on insulator 11 one end, described upper contact head 12 is fixedly connected with connecting plate 2, described connecting plate 2 is connected with pull hook 3, and described pull hook 3 is riveted by rivet 4 with connecting plate 2.
The position that described pull hook 3 is connected with connecting plate 2 strikes out tabular and forms link 31, described link 31 is provided with connecting through hole 311, on described connecting plate 2, the position of corresponding connecting through hole 311 is provided with and installs through hole 21, and rivet 4 runs through connecting through hole 311 and installs through hole 21 realization riveted joint.Pull hook 3 is formed after link 31 through punching press and is directly riveted on connecting plate 2 by rivet 4, and easy to connect, stable, efficiency is high, does not need human weld, reduces cost of labor and relatively welds more attractive in appearance.
End face and the connecting plate 2 of the relative connecting plate 2 of described link 31 are fitted.Link 31 and connecting plate 2 are fitted, the contact area of both increases, lessly rock, and further increase the stability that link 31 is connected with connecting plate 2.
Rivet 4 is with connecting through hole 311 and install through hole 21 all interference fit.Rivet 4 with connecting through hole 311 with after installing through hole 21 interference fit, the increase pull hook 3 of a step and the stable, firm of connecting plate 2 again in the riveting process of rivet 4.
The thickness of described link 31 is 3/5ths of pull hook 3 diameter.Link 31 thickness that punching press is formed, at 3/5ths of pull hook 3 diameter, ensure hardness and the useful life of link 31, make its not easy fracture.
Rivet 4 is provided with two, the connecting through hole that coordinates with rivet 4 311 and install through hole 21 and be equipped with two.The quantity of rivet 4 is two, when ensureing the stability that connecting plate 2 is connected with pull hook 3, avoiding waste and increasing unnecessary cost.
Two rivets 4 distribute along the length direction of link 31.Link 31 broadband that punching press is formed is less relative to its length, and two rivets 4 distribute along the length direction of link 31, active force disperse evenly.
Rivet 4 is riveted on pull hook 3 and connecting plate 2 with after metal-to-metal adhesive.Rivet 4 with metal-to-metal adhesive is riveted and is bonded on pull hook 3 and connecting plate 2, stable, fastness is higher.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
