The effect of electric vehicle high-voltage electric appliance box is some hi-lo circuit plates, high-low pressure insurance and high-low voltage relay
Set is mounted together, and can effectively be completely cut off driver and be touched high-voltage wiring harness and component, while facilitating engineering replacement insurance etc.
Easily worn part.Electric vehicle engineering is in developing stage at present, technically still immature, need through normally open high pressure electric appliance box into
Row checks the work such as maintenance, and the high pressure electric appliance box used now is bolted mostly, when needing to open, needs
Bolt is all backed out, is screwed on again after maintenance, it is very inconvenient.So still remaining high pressure in actual vehicle operation
The case where electrical appliance kit water inlet, causes internal circuit board to corrode, high-pressure system insulation fault.
Therefore it designs one kind and had not only been able to satisfy waterproof cooling requirement, but also can be very heavy convenient for the high pressure electric appliance box frequently opened
It wants.
Utility model content
For above situation, for the defect for overcoming the prior art, the utility model provides a kind of screw-on High-Voltage Electrical Appliances
Box, it is inconvenient that effective solution high pressure electric appliance box installation is opened, while sealing the bad problem of gas permeability.
A kind of screw-on high pressure electric appliance box, the technical solution solved include shell, and the inside of shell is equipped with horizontal positioned
Ceramic wafer, the air holes of multiple vertical perforation ceramic wafers are offered on ceramic wafer, enclosure interior is divided into up and down by ceramic wafer
The top plate of two parts, shell is equipped with dismountable plug, is threadedly coupled between plug and the top plate of shell, plug is placed in
Box body exterior portion is fixed with disk, and the diameter of disk is greater than plug diameter, there are gap between disk and the upper surface of shell,
Multiple circumference uniform distributions are offered on plug and section is the heat release hole of L-type, the lower end surface of vertical one end perforation plug of heat release hole
It is connected to enclosure interior, the lower end surface of lateral one end perforation disk of heat release hole is simultaneously connected to outside.
The utility model clever structure, it is novel, it can be very good to realize electric appliance by being placed in the plug above shell
The opening and closing of box and the heat dissipation of interior of electrical box.
Detailed description of the invention
Fig. 1 is the utility model main view.
Fig. 2 is the utility model top view.
Fig. 3 is partial enlarged view in the utility model Fig. 1.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
By Fig. 1-3 it is found that the utility model includes shell 1, the inside of shell 1 is equipped with horizontal positioned ceramic wafer 2, ceramics
Offer the air holes 3 of multiple vertical perforation ceramic wafers 2 on plate 2, ceramic wafer 2 by 1 inside division of shell at upper and lower two parts,
The top plate of shell 1 is equipped with dismountable plug 4, is threadedly coupled between plug 4 and the top plate of shell 1, plug 4 is placed in box body
Exterior portion is fixed with disk 5, and the diameter of disk 5 is greater than 4 diameter of plug, between existing between disk 5 and the upper surface of shell 1
Gap, multiple circumference uniform distributions are offered on plug 4 and section is the heat release hole 6 of L-type, vertical one end perforation plug 4 of heat release hole 6
It is connected to inside lower end surface and shell 1, the lower end surface of lateral one end perforation disk 5 of heat release hole 6 is simultaneously connected to outside.
It is equipped with multiple electric mounting rooms 7 above the ceramic wafer 2, is equipped in the left and right sidewall of shell 1 and pacifies with electric appliance
Fill the corresponding wire barrel 8 in 7 position of room.
The lower end of the plug 4 offers blind hole 9, the bottom wall and shell 1 of vertical one end perforation blind hole 9 of heat release hole 6
Inside connection.
The bottom wall of the blind hole 9 is equipped with air extractor 10.
The plug 4 is placed in the outer circle outside shell 1 equipped with annular convex platform 11, and the lower end surface of annular convex platform 11 is equipped with close
Seal 12, the lower end surface that plug 4 is screwed into annular convex platform 11 after shell 1 are fitted closely with 1 upper surface of shell.
The utility model is first turned on plug 4 when specifically used, and each electric appliance original part is separately mounted to different electricity
Device install room 7 in, then wire barrel 8 that high-tension bus-bar is passed through to two sides respectively is passed through inside shell 1, and respectively with corresponding electricity
Device original part is attached, and after the completion of connection, plug 4 is screwed on the top plate of shell 1, and being connected through a screw thread can be in certain journey
Realize that the leakproofness of plug 4 and 1 connecting portion of shell screws downwards in plug 4 and 1 connection procedure of shell in plug 4 on degree
In the process, it since 4 outer circle of plug is equipped with annular convex platform 11, is screwed as plug 4 is downward, the lower end surface meeting of annular convex platform 11
It is in close contact with the upper surface of shell 1, realization sealing ring 12 is fitted closely with 1 upper surface of shell, realizes good sealing effect
Fruit；After installation is complete, in order to preferably realize the heat dissipation of the electric appliance original part in shell 1, it can star and be placed on 9 bottom wall of blind hole
Air extractor 10 so that during the work time electric appliance original part generate heat flowed up under the action of air extractor 10,
And outside is flowed to by plug 4 by heat release hole 6, it realizes to the heat dissipation inside shell 1, convenient for the electric appliance original part of interior of electrical box
Preferably work.
Additionally due to heat release hole 6 is connected in outside with the lower end surface of disk 5, internal heat outflow can be made, but it is outer
The liquid in portion is but not easy to enter inside shell 1 by heat release hole 6, avoids external moisture by heat release hole 6 and enters electric appliance
Cause the damage of electric appliance original part in the inside of box.
Furthermore in the case where exceedingly odious, electrical appliance kit in use, may enter water, when moisture enters, water
Branch flows into the lower section of ceramic wafer 2, will not impregnate electric appliance original part, further avoid causing danger.
The utility model clever structure, novel, the plug 4 by being placed in 1 top of shell can be very good to realize electricity
The opening and closing of device box and the heat dissipation of interior of electrical box.
