Description
Technical field
The utility model relates to a kind of fuse, divides belong to technical field of electric equipment by International Patent Classification (IPC) (IPC).
Background technology
Fuse (fuse) refers to when electric current exceedes setting, with the heat that itself produces, melt is fused, a kind of electrical equipment of open circuit.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten, thus circuit is disconnected with the heat that himself produces; Use a kind of current protector that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.
At present, existing fuse is provided with grounding connection bar, this grounding connection bar is called that ground connection is obstructed in industry, and ground connection stalk is positioned at support and is positioned at outlet terminal place, be arranged in parallel with connecting rod, earth brace and earth connection complex steps in so just realizing to equipment and not easy to operate, bring very big inconvenience.
Thus, the present inventor considers to improve existing fuse structure, and this case produces thus.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of fuse that the sealing of a kind of rational in infrastructure, convenient to use, product is neat, two ends limb error is less, production efficiency is higher and cost is low.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of fuse, this fuse comprises insulator, into and out of line terminals, connecting rod, and ground connection stalk, describedly lay respectively at the two ends of insulator into and out of line terminals and be connected with corresponding end, wherein outlet terminal is connected with support, and support is provided with fuse, and connecting rod one end and input terminal coordination hinge, the other end realizes with the contact of fuse or is separated; Aforementioned brackets is metallic conductor, and its side is provided with ground connection stalk.
Further, described ground connection stalk is the bending body of rod, and its one end is installation end and is connected with aforementioned brackets, and the other end is free end; Described installation end offers thread segment, and the screw that this thread segment is corresponding with on support coordinates and forms ground connection and obstruct and the syndeton of support.
Further, described ground connection stalk is socketed with stop nut, and this stop nut is positioned on the installation end of ground connection stalk.
Further, the free end bending of described ground connection stalk, forms the ground connection stalk structure of L shape.
Further, described ground connection stalk is also provided with earthing clamp for being connected with earth connection by ground connection stalk.
Further, described earthing clamp is a metal clamp.
Further, described ground connection stalk outer surface is smooth shape.
Further, described ground connection stalk outer surface concave-convex surface.
Further, the outer surface of described ground connection stalk is concavo-convex is by offering multiple annular groove in smooth Metallic rod, or ground connection stalk outer surface itself forms concaveconvex structure, and its protrusions is taper or arc-shaped etc.
Further, the bottom surface of aforementioned each annular groove or depression is plane or arc-shaped or cone-shaped etc., and opening direction is towards groove upper end.
Compared with prior art, advantage of the present utility model:
The position that ground connection is obstructed by the utility model changes, and adopts earthing clamp to be mated realization and the connection of earth connection, makes it easy for installation, guarantees the stable connection degree with earth connection simultaneously, thus guarantee the safe handling of fuse.
