Description
Technical field
The utility model belongs to the electric machine controller field of electric car, more particularly, to a kind of company for electric machine controller
Binding structure.
Background technology
With the continuous development of electric automobile, the constantly improve of relative various standards, its property indices will
Seek also more and more higher.Controller for electric vehicle is for controlling the startup of electric vehicle motor, operation, advance and retreat, speed, stopping and electricity
The kernel control chip of other electronic devices of motor-car, it is like the brain of electric car, is part important on electric car, its
It is connected by cable with motor.
Cable is provided with the screen layer for being grounded, in order to ensure good earthing effect, generally in screen layer outer sheath
Jointing and then the crimping sleeve on the outside of jointing are connect, ensures jointing and screen layer by being pressed on sleeve pipe
Between good contact, in order to ensure the firm connection between jointing and cable, sleeve pipe is from jointing to length of cable
Direction extends.
The jointing of existing said structure is generally connected on cable by glue sealing, and marine glue is normal at normal temperatures
Air-drying needs the long period, and easily cable is polluted when marine glue is smeared, and influences the overall appearance of cable, shields
Cover that layer contact area is smaller, and shield effectiveness is undesirable, the area of sleeve pipe is larger, and production cost is high, and sealing ring is connected to connection and connect
Head outside, sealing effectiveness is poor, and waterproof hidden danger is larger, also easily damaged during installation.
Utility model content
For overcome the deficiencies in the prior art, a kind of production cost of the utility model offer is low, shield effectiveness is good, water proofing property
Energy is strong, assembles the attachment structure for being simply to electric machine controller.
Technical scheme is used by the utility model solves its technical problem：A kind of connection knot for electric machine controller
Structure, located at the wire harness for connecting motor, the wire harness is provided with screen layer, and the attachment structure is included on wire harness
Adapter sleeve and jointing, under the jointing includes the portion of upper body being tightly connected with wire harness and is sheathed on the outside of adapter sleeve
Portion's body, the screen layer are located between the lower body and adapter sleeve.Traditional screen layer is changed to connect with jointing inwall
Touch the structure of connection, adapter sleeve, screen layer and jointing three parallel laying from inside to outside, by being pressed on jointing
Connect, not only realize the firm connection of adapter sleeve and jointing and wire harness, and ensure that the effective of screen layer and attachment structure
Contact area, avoid producing wire harness larger damage during crimping；Adapter sleeve length only need to be identical with lower body, without prolonging
Extend on the outside of wire harness, saved the making material of adapter sleeve, reduced the production cost of adapter sleeve.
Further, the shielding layer segment is in the wire harness, after partly extending wire harness bending insert lower body and company
Between female connector.Shielding layer segment is stretched into wire harness, and part bending is set on the outside of wire harness, and its one side contacts with adapter sleeve, separately
Side is contacted with the inwall of jointing, and not only attachment structure is firm, and the contact with jointing and adapter sleeve is more filled
Point；And when jointing outer wall crimps, due to more, thicker protective layer, being not damaged inside wire harness, become
Shape is few.
Further, seal is provided between the portion of upper body and wire harness.Connected by seal, eliminate marine glue painting
The step of covering, assembly technology is simpler, and linkage editor is simplified, and has prevented wire harness caused by marine glue and has polluted.
Further, the seal inwall is provided with the primary sealing area that can coordinate with jointing and wire harness sealing.
Further, the primary sealing area is step-like structure.The step-like structure and jointing of seal inwall
Top surface offset, ensure that the waterproof effect of seal, avoid wire harness from intaking.
Further, the seal outer wall, which is provided with, to seal the secondary sealing area coordinated with motor controller casing.
Further, the secondary sealing area includes multiple sealing rings be arrangeding in parallel.Secondary sealing area can effectively be kept away
Exempt from the water inlet of electric machine controller shell, cyclic structure somewhat to have deviation between seal and housing it is also ensured that sealing effect
Fruit.
Further, the seal is provided with the convex edge that can be offseted with jointing.Convex edge can be with electric machine controller
Shell offsets, and increases the contact area of seal and jointing, is effectively increased sealing property, also increases the support of seal
Power, reduce the deformation of seal.
Further, the lower body and adapter sleeve are crimped on wire harness.
The beneficial effects of the utility model are：Assembling structure simplifies, and production efficiency is high, and cost reduces, and shield effectiveness is good, prevents
Water-based energy is strong.
