Technical field
The utility model relates to a kind of casing of electric vehicle controller sealing mechanism.Specifically, be the sealing mechanism that seals between the wire fairlead on the casing of electric vehicle controller baffle plate and sealing head.
Background technique
All know at the casing of electric vehicle controller production industry, all be processed with on the baffle plate of casing of electric vehicle controller and be convenient to the wire fairlead that wire passes.Because controller for electric vehicle all is under the use state in the open-air atmosphere, enters in the controller for electric vehicle from the wire fairlead for avoiding rainwater, just must the wire fairlead on the baffle plate be sealed.Therefore, the wire fairlead place on the casing of electric vehicle controller baffle plate all is provided with sealing mechanism.Traditional sealing mechanism comprises a locking head and gasket seal, described locking head is tubulose, is processed with screw thread on its cylindrical, and the centre of its outer side surface is processed with circumferential chimb, the one end is furnished with locking nut, and its other end screws under installment state in the wire fairlead on the baffle plate.For realizing the sealing when between plate and casing of electric vehicle controller, between baffle plate and casing of electric vehicle controller, also be provided with gasket seal.Be processed with on the described gasket seal and be convenient to the through hole that sealing head passes.During installation, to seal first in the wire fairlead on the first end screw-in casing of electric vehicle controller baffle plate, and gasket seal is placed between casing of electric vehicle controller baffle plate and the casing of electric vehicle controller, with screw gasket seal, casing of electric vehicle controller baffle plate and casing of electric vehicle controller are fixed together again, make the lighting outlet of controller pass successively gasket seal, locking head and be coated in the locking head with sealer, at last, locking nut is screwed on the sealing head outer end, thereby has realized the sealing of the wire fairlead on the casing of electric vehicle controller baffle plate.There is following shortcoming in this sealing mechanism: the one, owing to be processed with screw thread on the locking head, need to adopt hard material, and the individual part so that locking head and gasket seal are respectively done for oneself needs two moulds, so that equipment investment is more, cost of production is high during production; The 2nd, owing to need to be processed with screw thread on the sealing head cylindrical, and be also to need locking nut to lock in installation, the part that needs is many, so that complex structure, installation steps are many, and manufacturing efficiency is low.
The model utility content
Problem to be solved in the utility model provides a kind of casing of electric vehicle controller wire fairlead sealing mechanism.This sealing mechanism, cost of production is low, and is simple in structure, and manufacturing efficiency is high.
For overcoming the above problems, take following technological scheme:
Casing of electric vehicle controller wire fairlead of the present utility model comprises gasket seal with sealing mechanism, and the sealing pad is flexible sheet.Be characterized on the one side of described gasket seal the flexible sealing head being arranged.Described flexible sealing head is short tube, and one end and gasket seal form as one.With on the corresponding gasket seal of flexible sealing head internal diameter the wire fairlead is arranged.Have on the end cylindrical that the flexible sealing head links to each other with gasket seal and be convenient to the circumferential recess that cooperates with wire fairlead on the casing of electric vehicle controller baffle plate, the groover rot diameter of described circumferential recess is equal to or greater than the wire fairlead on the described casing of electric vehicle controller baffle plate.
Be connected with fanning strip around the wire fairlead on the gasket seal of the present utility model.Form as one around the arc-shaped side of described fanning strip and the wire fairlead on the gasket seal, and under non-working condition, contact between the straight flange of adjacent fanning strip.
Wherein, the cylindrical of described flexible sealing head is taper, and its large end links to each other with described gasket seal.Described flexible sealing head and gasket seal are rubber product or plastic article.
Take such scheme, have the following advantages:
Can be found out by such scheme, owing on the one side of described gasket seal the flexible sealing head is arranged.Described flexible sealing head is short tube, and one end and gasket seal form as one.With on the corresponding gasket seal of flexible sealing head internal diameter the wire fairlead is arranged.Have on the end cylindrical that the flexible sealing head links to each other with gasket seal and be convenient to the circumferential recess that cooperates with wire fairlead on the casing of electric vehicle controller baffle plate, the groover rot diameter of described circumferential recess is equal to or greater than the wire fairlead on the described casing of electric vehicle controller baffle plate.During installation, only need front end with sealing head below baffle plate, stretch in the wire fairlead and with hand one by, just can make in the circumferential recess that snaps in around the wire fairlead of described baffle plate on the sealing head, do not need nut, do not need threading on the sealing head cylindrical, just can realize the sealing between sealing head and wire manhole appendix, the part that needs is few, simple in structure, installation steps are few, and manufacturing efficiency is high.Because the first end of described flexible sealing and gasket seal form as one, need two moulds to compare with background technique again, only need a mould, the mould of use is few, can reduce equipment investment, reduces production costs.
