2, tube body material uses melamine;3, the small product size of corresponding safe assembly switch exploitation is bigger than normal, causes it EV's
Application space is limited, how to realize the improvement of fuse assembly device, reduces volume, improves performance, extends product service life,
As major manufacturer's urgent problem.
Utility model content
The utility model the technical problem to be solved is that: a kind of fuse assembly device of novel high-performance high current is provided,
The drawbacks of above-mentioned known technology can be overcome is the widely applied trend of the industries such as current new energy.
In order to solve the above technical problems, the utility model provides a kind of fuse assembly device of novel high-performance high current, packet
Include fuse porcelain tube, contact pin, bending copper bar, cover board and screw；Wherein bending copper bar is located on fuse porcelain tube；Wherein contact pin
It is located on bending copper bar；Its cover plate is located on bending copper bar；Wherein cover board and bending copper bar are fixed on fuse by screw
On porcelain tube.
It advanced optimizes, the contact pin is preferably 10.0mm；After the bending copper bar and contact pin are pressed using interference fit
Fibre is welded.
It advanced optimizes, the bending copper installation on fuse porcelain tube, then matches upper cover plate, finally use screw
Nail is locked.
It advanced optimizes, the preferred number of contact pin is 2；The preferred number of bending copper bar is 2；The cover board is used
Blocking preferred number is 2；The preferred number of screw is 8.
It advanced optimizes, the screw is respectively provided at four angles of each cover board；Cover board is fixed.
It advanced optimizes, the cover board is 2；The cover board is covered respectively on bending copper bar.
It advanced optimizes, the bending part of the bending copper bar is arranged on two angles of fuse porcelain tube.
It advanced optimizes, the tube body material of the fuse porcelain tube is using ceramics；The fuse porcelain tube is preferably No. 000
Porcelain tube, having a size of 21*36.
After above-mentioned technical proposal, the beneficial effects of the present invention are:
Scheme compared with the prior art provides Novel DC charging pipette tips to design by this, provides pure electric vehicle vapour
The preferred plan of vehicle, reliability, compactedness, conduction high efficiency, space be small, cost savings and facilitates the high-performance of maintenance big
The product development of the safe assembly switch of electric current small size.
1, fuse uses No. 000 porcelain tube, and size: 21*36 is effectively saved the overall space of fuse assembly;
2, the tube body material of fuse assembly is better than melamine material, pressure voltage using ceramics, internal arc quenching effect
Increase;
3, generally result in safe assembly switch product development volume it is bigger than normal be the space because of the component of layout fuse
Greatly, this fuse assembly device is now used, space is just substantially reduced, reduces weight, automobile is effectively avoided to generate shake in movement
It is dynamic to damage fuse tubular body structure and cause to fail.
Detailed description of the invention
Fig. 1 is a kind of structure chart of the fuse assembly device of novel high-performance high current
Fig. 2 is a kind of overall diagram of the fuse assembly device of novel high-performance high current
Specific embodiment
The utility model is described in detail in 1 and Fig. 2 specific embodiment with reference to the accompanying drawing, but not as the limit to the utility model
It is fixed.
As shown in Figure 1 and Figure 2, a kind of fuse assembly device of novel high-performance high current, including fuse porcelain tube
1, contact pin 2, bending copper bar 3, cover board 4 and screw 5；Wherein bending copper bar 3 is located on fuse porcelain tube 1；Wherein contact pin 2 is located at
On bending copper bar 3；Its cover plate 4 is located on bending copper bar 3；Wherein cover board and bending copper bar 3 are fixed on fuse by screw 5
On porcelain tube 1.The most preferably preferably 10.0mm of contact pin 2；Fibre weldering is welded after the bending copper bar 3 is pressed with contact pin 2 using interference fit
It is good.Bending copper bar 3 is mounted on fuse porcelain tube 1, then matches upper cover plate 4, is finally locked with screw 5.Contact pin 2 is most
Good preferred number is 2；The best preferably number of bending copper bar 3 is 2；The cover board 4 is 2 with the best preferably number of card
