Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As Figure 1-4, it is the schematic diagram of the utility model high pressure through terminal embodiment, the high pressure through terminal can answer
For new energy car battery, motor and ECU, there can also be height with electric machine controller on industrial frequency transformer etc.
Piezoelectric forces electronic unit wiring.High pressure through terminal in the present embodiment includes housing 10, multiple sealing rings 30 and multiple locks
Tight part 20, above-mentioned housing are made up on (such as being made up of die casting) and the housing 10 with more of metal material (such as aluminium alloy)
Individual cable aperture 11 (such as 2 cable aperture 11 shown in Fig. 1-4 or 3 or more than 3 electricity for cable threading
Cable hole 11).(such as central shaft is parallel) is arranged side by side for above-mentioned multiple cable aperture 11 or be staggered (such as broken line, isosceles triangle
Deng), and each cable aperture 11 is included positioned at the first paragraph in line inlet port side (left side i.e. shown in Fig. 4) and positioned at line outlet side
The second segment on (right side i.e. shown in Fig. 4).Have between the first paragraph and second segment of the cable aperture 11 and protrude from the interior of first paragraph
The step of wall.The diameter matches of the external diameter of sealing ring 30 and the first paragraph of cable aperture 11, each sealing ring 30 are placed in a cable
One end of the first paragraph in hole 11 and the sealing ring 30 is against step.There is the through hole that current supply cable passes through on each locking member 20, and
The sealing ring 30 that the locking member 20 is locked on the housing 10 and oppressed in the first paragraph of corresponding cable aperture 11 realizes sealing.
Specifically, locking member 20 can lock on the housing 10 in the following manner：The spiral shell in the inwall of cable aperture 11 is set
Line, and at least one of periphery of locking member 20 has external screw thread, locking member 20 is locked by the cooperation of external screw thread and internal thread
It is tightened to cable aperture 11.Now, when carrying out wiring using above-mentioned high pressure through terminal (assuming that the high pressure through terminal has been affixed to
Controller box), the terminals of cable are inserted into the through hole of locking member 20, sealing ring 30 is then put into cable aperture 11
First paragraph in and one end be resisted against on step；The line inlet port of the terminals of the cable from cable aperture 11 is inserted into cable aperture again
Passed in 11 and from line outlet；The locking member 20 being placed on cable is finally inserted into the first paragraph of cable aperture 11 simultaneously from line inlet port
Tighten, it is produced deformation, the inwall of filled cable and cable aperture 11 so as to oppress sealing ring 30 by step and locking member 20
Between gap, realize sealing.
Multiple water-proof cable holes 11 are integrated into a housing by above-mentioned high pressure through terminal, compare single water joint, can
Greatly save cost and assembly space.
Especially, the step in above-mentioned cable aperture 11 may be accomplished by：Make the straight of the second segment of cable aperture 11
Footpath is less than the diameter of first paragraph, and step is formed by the diameter difference of first paragraph and second segment, as shown in Figure 4.Certainly, in practical application
In, it can also make the first paragraph of cable aperture 11 identical with the diameter of second segment, so as to which step not only protrudes from the first of cable aperture 11
The inwall of section, also protrude from the inwall of cable aperture second segment.
To improve sealing effectiveness, the outer surface that can make sealing ring 30 is in bowl-type, and the outer surface of the sealing ring 30 is in step
The diameter of side is more than the diameter away from step side, i.e. the diameter of the periphery in the left side of sealing ring 30 in Fig. 4 is more than the periphery on right side
Diameter.By this way, sealing ring 30 can be urged to cable surface, realize sealing.
In addition, it can also make the inwall and the shape of the outer surface of sealing ring 30 that one end of sealing ring 30 is contacted on locking member 20
Matched with size.When locking member 20 is screwed into the first paragraph of cable aperture 11, the external diameter of sealing ring 30 is less to be inserted partially into
The larger part of internal diameter on locking member 20, continues to turn locking member 20, can oppress sealing ring 30 and be properly fit onto cable surface,
So as to realize sealing.
To realize that high voltage cable shields with power electronics unit, shading ring 40 can be increased in above-mentioned high pressure through terminal.
Specifically, a shading ring 40 can be set in each cable aperture 11, and the shading ring 40 can be located at the second segment of cable aperture 11.
As described in Fig. 2,4, above-mentioned shading ring 40 may include multiple flexure strips, and the plurality of flexure strip is around the of cable aperture 11
Two sections of central shaft is uniformly distributed.Particularly, the free end of above-mentioned multiple flexure strips is in claw type, its outlet towards cable aperture 11
Mouth is simultaneously projected into the second segment of cable aperture 11, so as to hold cable tightly when cable inserts, is greatly improved shield effectiveness.
Above-mentioned high pressure through terminal is installed to the cabinet of controller for convenience, outside the second segment of all cable aperture 11
There is the groove around the periphery of cartridge part 14 formed with cartridge part 14 on housing 10, on the cartridge part 14, and assembled in groove
Have sealing filler (such as：Sealing ring) 50, so as to realize the sealing between cabinet and housing 10.
On the housing 10, at least two lugs 12 being projected into above the groove of cartridge part 14, each lug can also be increased
There can be fixing hole 13 on 12, consequently facilitating the mechanical means such as being connected by screw by high pressure through terminal and controller machine
Box main body is fixedly connected.Pass through top fixing hole and radial seal structure so that high pressure through terminal can be thoroughly broken away from using peace
Reserved this limitation of spanner space is needed when filling panel construction, saves space.When the control using above-mentioned high pressure through terminal
When device processed is on vehicle, the relatively existing above-mentioned top fixed structure of side mounting structure not only saves space, and repairs
It is convenient.
The utility model also provides a kind of controller, including cabinet and in cabinet power electronics unit (such as
IGBT etc.), one or more above-mentioned high pressure through terminals are wherein equipped with cabinet, external high pressure cable presses through line by height
Terminal connects controller.
It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, any one skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should
It is defined by scope of the claims.
