Description
Technical field
The utility model belongs to fuse technologies field more particularly to a kind of fuse piece and the fuse containing the fuse piece.
Background technique
Fuse is when electric current is beyond specified value, and the heat generated with itself makes one kind of melt fusing, disconnecting circuit
Electric appliance, the protector as short circuit and overload current are widely used in high and low voltage electric distribution system, control system and electrical equipment,
So having extensive market prospects in popularizing for fuse.Existing fuse includes fusion tube, the quartz sand in fusion tube
Cover board with fuse piece and positioned at fusion tube two sides.As shown in Fig. 1, in the prior art, fuse piece includes several first main parts 2
And the second main part 3 being connected between several first main parts 2, the top edge of the first main part 2 and lower edge are symmetrically set
It is equipped with recess position 4, the first main part 2 is additionally provided with through-hole 5.It is arranged so that connection position (5 edge of through-hole to recess 4 side of position
The distance of edge) it is too small, what is had is small to 0.1mm or so width, easily damages and is broken, there are security hidden troubles.
In view of this, the fuse it is necessory to provide the new fuse piece of one kind and containing the fuse piece is asked with solving above-mentioned technology
Topic.
Utility model content
One of the purpose of this utility model is: in view of the deficiencies of the prior art, and providing a kind of fuse piece, improves product
Robustness and safety coefficient reduce fraction defective, it is ensured that it can carry out safely overcurrent protection in circuit.
To achieve the goals above, the utility model uses following technical scheme:
A kind of fuse piece, including several first main parts and the second main body being connected between several first main parts
Portion, the top edge of first main part and lower edge are symmetrically provided with recess position, and second main part is provided with through-hole,
Vertical range between the highest point of the through-hole and the top edge of second main part is greater than 1mm, the through-hole it is minimum
Vertical range between point and the lower edge of second main part is greater than 1mm.
As a kind of improvement of fuse piece described in the utility model, the ultra-left point of the through-hole and second main part
The distance between left edge is greater than 0.1mm.
As a kind of improvement of fuse piece described in the utility model, the rightest point of the through-hole and second main part
The distance between right hand edge is greater than 0.1mm.
As a kind of improvement of fuse piece described in the utility model, the shape of the through-hole is round, ellipse or polygon
Shape.
By using above-mentioned technical proposal, there are enough distances between the edge of through-hole and the edge of the second main part,
I.e. connection position is wider, therefore effectively can avoid damage to and be broken, and improves the robustness and safety coefficient of product, reduces fraction defective,
Ensure that it can carry out safely overcurrent protection in circuit.
The two of the purpose of this utility model are: providing a kind of fuse, including fuse tube, pipe cap and fuse piece, the pipe
Cap is set to the both ends of the fuse tube, and the fuse piece is set in the fuse tube, and the fuse piece is institute above in specification
The fuse piece stated.
By using above-mentioned technical proposal, fuse of the invention have more preferably robustness and safety, can more added with
Safety carries out overcurrent protection in circuit on effect ground.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of fuse piece in the prior art.
Fig. 2 is the structural schematic diagram of fuse piece in the present invention.
Fig. 3 is the structural schematic diagram of fuse in the present invention.
Wherein: 1- fuse piece, the first main part of 2-, the second main part of 3-, 4- recess position, 5- through-hole, 6- fuse tube, 7- pipe
Cap.
Specific embodiment
With reference to embodiment and Figure of description, the utility model is described in further detail, but this
The embodiment of utility model is not limited to this.
As shown in Fig. 2, a kind of fuse piece, including several first main parts and be connected between several first main parts
Two main parts, the top edge of the first main part and lower edge are symmetrically provided with recess position, and the second main part is provided with through-hole, lead to
Vertical range between the highest point in hole and the top edge of the second main part is greater than 1mm, the minimum point of through-hole and the second main part
Lower edge between vertical range be greater than 1mm.
Preferably, the distance between left edge of the ultra-left point of through-hole and the second main part is greater than 0.1mm.
Preferably, the distance between right hand edge of the rightest point of through-hole and the second main part is greater than 0.1mm.
Preferably, the shape of through-hole is round, ellipse or polygon.
Embodiment 2
As shown in figure 3, a kind of fuse, including fuse tube, pipe cap and fuse piece, pipe cap are set to the both ends of fuse tube, melt
Piece is set in fuse tube, and fuse piece is the fuse piece in embodiment 1.
According to the disclosure and teachings of the above specification, the utility model those skilled in the art can also be to above-mentioned reality
The mode of applying is changed and is modified.Therefore, the utility model is not limited to above-mentioned specific embodiment, all this field skills
