Description
Technical field
The utility model belongs to circuit protection device technical field more particularly to a kind of Surge Protector field.
Background technique
Contact between the graphite electrode of the graphite discharging device of existing Surge Protector and spray point is by stone
Electrode ink side processes depressed section, and electrode is set on the depressed section, if notification number is that CN206774686U patent name is
The patent of Surge Protector special graphite electrode, the patent graphite electrode side need to process depressed section, and depressed section adds
Work required precision is higher, needs to be accurate to 0.01mm, and manufacture difficulty is big, and scrappage is high, and yield rate is low, and spray point and electrode
Contact portion is only the surface at depressed section, due to the thickness requirement of graphite electrode make the contact portion of spray point and electrode compared with
Small, impact resistance ability can also further increase.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of Surge Protector graphite that impact resistance ability is strong to put
Electric installation.
The utility model is achieved by the following technical solution:
Surge Protector graphite discharging device, including graphite flake, spray point and gasket, spray point include interconnecting piece and put
Electric portion, discharge part are fixedly connected with interconnecting piece, the side setting of the interconnecting piece fitting graphite flake of spray point.
The utility model has the beneficial effects that the side of the interconnecting piece fitting graphite flake of the utility model spray point, so that putting
Contact effect of the acusector with graphite flake is more preferable, and when by rush of current, the flow area of graphite flake is bigger than traditional structure, from
And impact resistance is more preferable, improves 5% or so compared to traditional product performance by testing the utility model.

Specific embodiment
Below with reference to embodiment, the utility model is described in further detail.
Embodiment
Surge Protector graphite discharging device as shown in figs 1-9, including graphite flake 1, spray point 2 and gasket 3, gasket
3 are set between adjacent two graphite flake 1, and several graphite flakes 1 are alternatively arranged with gasket 3, and then both sides are arranged clamping plate 4 and by tight
The fixed locking of firmware 5, spray point 2 includes interconnecting piece 21 and discharge part 22, and discharge part 22 is fixedly connected with interconnecting piece 21, preferably
Integral type one-pass molding structure, the interconnecting piece 21 of spray point 2 are bonded the side setting of graphite flake 1, the material of the spray point
For conductive metal.The interconnecting piece 21 of spray point 2 is bonded the side of graphite flake 1, so that the contact effect of spray point 2 and graphite flake 1
More preferably, when by rush of current, the flow area of graphite flake 1 is bigger than traditional structure, so that impact resistance is more preferable, by reality
It tests the utility model and improves 5% or so compared to traditional product performance.
It is planar structure by the lateral layout of the graphite flake 1 for the contact effect of interconnecting piece 21 and graphite flake 1.
The side of graphite flake 1 is that plane enables it to come into full contact with interconnecting piece 21, increases the flow area of the two, to improve production
The impact resistance of product.
In order to further ensure the flow area of interconnecting piece 21 and graphite flake 1,21 width of interconnecting piece is set to it is
It is preferably identical less than or equal to the thickness of graphite flake 1, herein certainly can not be identical in meaning, but close to identical,
Compared to traditional staircase structural model, in the case where not changing graphite thickness, contact aside area is greatly increased, if changing graphite
1 thickness of piece or reduce graphite flake 1 the piece number or product size will be increased, however both modes be obviously all can not
It takes, because the piece number reduction of graphite flake 1 then means that the number of plies successively discharged tails off, influences through-current capability；Increase product ruler
It is very little, make product weight big, it is at high cost etc..
According to the demand of client, the interconnecting piece 21 is designed as linear type or circle or U-shaped or polygonized structure.It is more
Side shape structure includes but is not limited to triangle, rectangle, pentagon, hexagonal structure.Number of edges is more, and contact effect is better, through-flow energy
Power is stronger.
In order to which discharge part 22 and 21 structure of interconnecting piece simply consider, the discharge part 22 is welded with interconnecting piece 21.Weldering
Connect convenient and efficient, production easy to process.
In order to enable the interconnecting piece 21 of spray point 2 not generate offset, by gasket 3 at least part be set to two graphite flakes 1 it
Between, between the interconnecting piece 21 that at least extends partially into adjacent two spray point 2.The design is so that the spray point 2 between two gaskets 3 connects
Socket part 21 will not deviate, to be further ensured that the contact area of the interconnecting piece 21 of spray point 2 and the side of graphite flake 1, guarantee
The through-current capability of product.
In order to enable spray point 2 to protect graphite flake 1 non-friable, the interconnecting piece 21 is surrounded to the week of graphite flake 1 entirely
Side.Make graphite flake 1 broken since 2 side of spray point encloses graphite flake 1 in this way, to improve the service life of product
And through-current capability (part is broken to will lead to contact area reduction, reduces through-current capability).
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, it is on the premise of not departing from the spirit and scope of the utility model, in the art common
Simply changing and replacing for technical staff be all within the protection scope of the utility model.
