Abstract
The utility model provides a high contact surface fuse, including the fuse body, the fuse body includes body, connecting terminal, the both ends of body are provided with the end cap be provided with the lug on the end cap connecting terminal is last be provided with with the through -hole that the lug matches, the lug butt fusion is connected the through -hole. The quantity of lug is two, and the symmetry sets up on the end cap. The lug with end cap integrated into one piece, the lug is formed by the punching press. The body with be provided with interior cap between the end cap it is protruding that the end cap inboard is provided with the card be provided with on the interior cap with the recess of the protruding matching of card. Beneficial effect: the utility model provides a pair of high contact surface fuse has improved area of contact greatly to the electricity performance of fuse has been improved.
Description
Technical field
This utility model relates to fuse technologies field, particularly relates to a kind of high contact surface fuse.
Background technology
Fuse refers to when electric current exceedes setting, makes melt fuse with the heat that itself produces, and a kind of electrical equipment of disconnecting circuit, fuse is also known as electric fuse.Fuse is after exceeding setting a period of time according to electric current, makes Melt molten with the heat that himself produces, so that circuit disconnects；Use a kind of circuit brake that this principle is made.Fuse is widely used in high and low voltage electric distribution system and control system and electrical equipment, as the protector of short circuit and overcurrent, is apply one of most common protector.In prior art, the connection terminal of fuse is generally adopted riveting to end cap, is so easily caused connection terminal insufficient with contacting of end cap, can pass through electric current and greatly reduce, thus reducing the electric property of fuse.
Summary of the invention
This utility model provides a kind of high contact surface fuse, improves the contact area of end cap and binding post, and raising can pass through size of current.
In order to solve above-mentioned technical problem, technical solution adopted in the utility model is:
A kind of high contact surface fuse, including fuse, described fuse includes body, connects terminal；The two ends of described body being provided with end cap, is provided with projection on described end cap, be provided with the through hole mated with described projection on described connection terminal, described projection welding connects described through hole.
Preferably, the quantity of described projection is two, and is symmetricly set on described end cap.
Preferably, described projection is one-body molded with described end cap, and described projection is by being stamped to form.
Preferably, described connection terminal is L-shaped.
Further, between described body and described end cap, it is provided with interior cap, inside described end cap, is provided with card convex, described interior cap is provided with the groove mated with described card convex.
Preferably, in described body, it is filled with arc quenching material.
Preferably, described arc quenching material is quartz sand.
Preferably, described body is epoxy resin body or pottery body.
Preferably, described connection terminal is copper tip, the silver-plated terminal of copper or copper nickel plating terminal.
Preferably, outside described body, it is coated with explosion-proof layer.
This utility model provides a kind of high contact surface fuse, is provided with projection, is provided with the through hole mated with described projection on described connection terminal on described end cap, and described projection welding connects described through hole；Thus substantially increasing contact area, improve the electric property of fuse.
Accompanying drawing explanation

Fig. 2 is a kind of high contact surface fuse partial structurtes schematic diagram of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, specifically illustrating embodiment of the present utility model, accompanying drawing is only for reference and illustrates to use, and does not constitute the restriction to this utility model scope of patent protection.
As shown in Figure 1, 2, a kind of high contact surface fuse, including fuse, described fuse includes body 1, connects terminal 2；The two ends of described body 1 being provided with end cap 3, is provided with projection on described end cap 3, be provided with the through hole 21 mated with described projection on described connection terminal 2, described projection welding connects described through hole 21.The quantity of described projection is two, and is symmetricly set on described end cap 3.Described projection is one-body molded with described end cap 3, and described projection is by being stamped to form.Described connection terminal 2 is L-shaped.Between described body 1 and described end cap 3, it is provided with interior cap 4, inside described end cap 3, is provided with card convex, described interior cap 4 is provided with the groove 41 mated with described card convex.It is filled with arc quenching material 12 in described body 1.Described arc quenching material 12 is quartz sand.Described body 1 is epoxy resin body or pottery body.Described connection terminal 2 is copper tip, the silver-plated terminal of copper or copper nickel plating terminal.It is coated with explosion-proof layer 11 outside described body 1.
Above disclosed it is only preferred embodiment of the present utility model, it is impossible to limit rights protection scope of the present utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
