Utility model content
The purpose of this utility model is providing a kind of junction box structure of electric vehicle motor controller, solved and existingly caused the problem that controller size is large because of external terminal box, reduce waterproof and the installation of terminal box and controller housing simultaneously, reduced technology difficulty and installation procedure.
The technical scheme that the utility model adopts is, a kind of junction box structure of electric vehicle motor controller, comprise controller housing, controller housing both sides are all provided with water joint, in water joint, be installed with cable nose, in controller housing, the position corresponding with water joint is connected with junction block, cable nose is connected with junction block by bolt, controller housing upper opening place is provided with controller upper cover, on controller, cover the position corresponding with junction block and have wiring hole, wiring hole place is provided with wiring port lid.
Feature of the present utility model is also,
Wherein a side of controller housing is provided with 3 water joints, and the opposite side of controller housing is provided with 2 water joints.
Wherein wiring hole Lower Half is provided with radially outstanding boss, and boss is provided with internal thread, and described wiring port lid is that the longitudinal section matching with wiring hole is the column structure of T shape, and the outer wall of wiring port lid smaller-diameter portion is provided with the internal thread matching with boss.
Wherein wiring port lid and bolt end face are provided with inner hexagonal hole.
Wherein between boss and wiring port lid, be provided with O RunddichtringO.
The beneficial effects of the utility model are that operation is quick, simple, quick, can effectively reduce production cost, can effectively reduce controller size, and wiring need not be taken controller upper cover apart, can complete fast wiring work.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The junction box structure of a kind of electric vehicle motor controller of the utility model, as shown in Figure 1, comprise controller housing 4, controller housing 4 both sides are all provided with water joint 5, in water joint 5, be installed with cable nose 6, in controller housing 4, the position corresponding with water joint 5 is connected with junction block 7, cable nose 6 is connected with junction block 7 by bolt 8, bolt 8 end faces are provided with inner hexagonal hole, controller housing 4 upper opening places are provided with controller upper cover 3, on controller upper cover 3, the position corresponding with junction block 7 has wiring hole 9, wiring hole 9 Lower Halves are provided with radially outstanding boss 10, boss 10 is provided with internal thread, wiring hole 9 places are provided with wiring port lid 1, wiring port lid 1 is that the longitudinal section matching with wiring hole 9 is the column structure of T shape, the outer wall of wiring port lid 1 smaller-diameter portion is provided with the internal thread matching with boss 10, wiring port lid 1 is that screw thread is screwed into the connected mode of wiring hole 9.
As shown in Figure 2, a side of controller housing 4 is provided with 3 water joints 5, and the opposite side of controller housing 4 is provided with 2 water joints 5, and wiring port lid 1 end face is provided with inner hexagonal hole.
As shown in Figure 3, between boss 10 and wiring port lid 1, be provided with O RunddichtringO 2.
Wiring step of the present utility model is as follows:
Step 1: take off wiring port lid 1, by wiring hole 9, unclamp and take out bolt 8;
Step 2: unclamp the clamp ring of water joint 5, cable nose 6, through water joint 5, is close on junction block 7, cable nose 6 is lock onto on junction block 7 with bolt 8;
Step 3: O RunddichtringO 2 is positioned on the boss 10 of wiring hole 9, wiring port lid 1 is locked to installation, wiring completes.
Advantage of the present utility model is:
1) without external terminal box, and adopt independent wiring hole design, reduced controller volume;
2) between wiring hole and shell wall, adopt screw thread and o type circle waterproofing design, can effectively meet waterproof requirement;
3) through reasonably calculating and analyzing, adopted the anti-structural design of falling into enclosure interior of bolt;
4) between each busbar, adopt separate form insulation measures;
5) conductive connection part divides by copper bar, and bolt compresses and connects conduction, and reliability is high.
Use the utility model to carry out controller wiring and need not pull down controller upper cover 3, reduced workflow and operation, save time.
