Description
Technical field
The Manual maintenance switch that new-energy automobile uses is the utility model is related to, specifically a kind of method of Manual maintenance switch
Blue sealing gasket.
Background technology
Manual maintenance switch (MSD) provides safety for pure electronic and hybrid vehicle high-voltage electric power system in maintenance
Repair and maintaining and the function of safeguard protection is played to power system.When carrying out high-pressure system maintenance, high pressure connection is disconnected, is protected
Protect maintenance personal's safety.When there is short circuit risk in high-pressure system, built-in fuse blows, protection high-pressure system safety.
Existing Manual maintenance switch and high voltage power distributing cabinet (PDU) junction increase a rubber gasket carry out both it
Between sealing, due to existing sealing gasket design can not effectively deform make up Manual maintenance switch companion flange deformation and
With reference to surface evenness problem, leak is also easy to produce in the environment of high temperature and vibration.Water is caused to be permeated by the sealing gasket of junction
Into high voltage power distributing cabinet so that the short circuit of high-voltage board, cause security incident.
Utility model content
The purpose of this utility model is solve problems of the prior art, there is provided a kind of method of Manual maintenance switch
Blue sealing gasket.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of flange gasket of Manual maintenance switch, it is described between Manual maintenance switch and high voltage power distributing cabinet
Flange gasket includes sealing pad body and sealed muscle, and the sealing pad body is back-shaped, and the sealed muscle is arranged on sealing gasket
On body.
Preferably, the sealed muscle is arranged on the contact surface of sealing pad body and Manual maintenance switch.
Preferably, the sealed muscle is arranged on the contact surface of sealing pad body and high voltage power distributing cabinet.
Preferably, the sealed muscle is separately positioned on sealing pad body contact with Manual maintenance switch and high voltage power distributing cabinet
Face.
Preferably, the sealed muscle is back-shaped and composition enclosed construction.
Further, mounting groove is provided with four angles of the sealing pad body, the sealed muscle is arranged on mounting groove
Outer end.
Preferably, the inner side of the sealed muscle overlaps with the cylindrical of mounting groove.
Further, the groove among the sealing pad body is provided with projection, the raised height phase with sealed muscle
With and with sealed muscle quantity it is identical.
Preferably, it is described raised to be back-shaped.
The beneficial effects of the utility model are：
The utility model is compensated because deforming the position with out-of-flatness by setting sealed muscle, solves integral sealing pad because becoming
Shape is insufficient and causes to seal the problem of failing.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the utility model embodiment structural representation.
Fig. 2 is the utility model embodiment A-A to sectional view；

Embodiment
Below in conjunction with accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
Chu, it is fully described by, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole realities
Apply example.The component of the utility model embodiment being generally described and illustrated herein in the accompanying drawings can be come with a variety of configurations
Arrangement and design.Therefore, the detailed description of the embodiment of the present utility model to providing in the accompanying drawings is not intended to limit below
Claimed the scope of the utility model, but it is merely representative of selected embodiment of the present utility model.Based on the utility model
Embodiment, the every other embodiment that those skilled in the art are obtained on the premise of creative work is not made, all
Belong to the scope of the utility model protection.
As shown in Figure 1 to 4, the utility model embodiment discloses a kind of flange gasket 1 of Manual maintenance switch, installation
Between Manual maintenance switch 4 and high voltage power distributing cabinet 2, the flange gasket 1 includes sealing pad body 11 and sealed muscle 12, institute
Sealing pad body 11 is stated to be back-shaped, the sealed muscle 12 is arranged on sealing pad body 11, and the utility model embodiment is by setting
Sealed muscle 12 is put to compensate because deforming the position with out-of-flatness, solving integral sealing pad causes sealing failure because deforming deficiency
Problem.
In the embodiment of the utility model one, the sealed muscle 12 is arranged on sealing pad body 11 and Manual maintenance switch 4
Contact surface.
In the embodiment of the utility model one, the sealed muscle 12 is arranged on sealing pad body 11 and high voltage power distributing cabinet 2
Contact surface.
In the embodiment of the utility model one, the sealed muscle 12 is separately positioned on sealing pad body 11 and opened with maintenance manually
The contact surface of 4 and high voltage power distributing cabinet 2 is closed, both ends is sealed.
In the embodiment of the utility model one, the sealed muscle 12 is back-shaped and composition enclosed construction, is avoided in water entrance
Portion.
In the embodiment of the utility model one, mounting groove 111, mounting groove are provided with four angles of the sealing pad body 11
For avoiding the bolt 5 for installing high voltage power distributing cabinet 2 and Manual maintenance switch 4, the sealed muscle, 1 is arranged on mounting groove 111
Outer end, prevent water enter mounting groove in, corrosion bolt 5.
In the embodiment of the utility model one, the inner side of the sealed muscle 12 overlaps with the cylindrical of mounting groove 111.
In the embodiment of the utility model one, the groove among the sealing pad body 11 is provided with projection 13, described convex
Rise it is 13 identical with the height of sealed muscle 12 and identical with the quantity of sealed muscle 12, will not be because of highly so in deformation process
Difference causes sealing to fail.
In the embodiment of the utility model one, described raised 13 be back-shaped.
When sealing plane compresses, sealed muscle 12 deforms first, then seals the redeformation of pad body 11.When sealing plane has
Buckling deformation, sealed muscle 12 are first filled with the space of deformation and then deformed under the change of pressure.Due to for installing high pressure
The mounting flange 3 of power distribution cabinet 2 and Manual maintenance switch 4 can deform warpage, and sealed muscle 12 can supplement the sky of the warpage of mounting flange 3
Between, when mounting flange 3 continues to push, sealed muscle 12 starts deformation and plays sealing function.
Preferred embodiment of the present utility model is the foregoing is only, is not limited to the utility model, for
For those skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model and former
Within then, any modification, equivalent substitution and improvements made etc., it should be included within the scope of protection of the utility model.
