PCB is drawn, usually two external power cords, three motor phase lines.
At present, the cylindrical binding post that larger current is walked on controller for electric vehicle is usually in circuit board by screw lock
On, the waterproof around binding post typically using filling casting glue or realizes waterproof sealing using modes such as O-shaped rubber rings, and
By the way of filling encapsulating, the requirement in terms of its complex process, and the adhesion to glue, high-low temperature resistant and technique is very
Height, more difficult find of existing market can meet the suitable glue of requirements, and the cost of this special glue will be special
It is high.In addition by the way of encapsulating, cause larger because of difficulty to after-sales service.And if using simple O-shaped rubber ring come real
If existing waterproof, its required precision to assembling is very high, comparatively ideal water resistance is extremely difficult to, if water resistance can not reach
If product requirement, the circuit board of interiors of products is easy to go to pot because of water inlet, so as to influence the safety of vehicle.
Utility model content
The problem of in order to solve not good waterproof effect around current binding post, complex process, the utility model purpose is：Carry
For a kind of binding post proof mechanism of water, the waterproof problem around binding post can be solved, assembling is simple and cost is low, it is convenient to tie up after sale
Repair, and multiple waterproof can be realized to improve the water resistance of product.
The technical solution of the utility model is：
A kind of binding post proof mechanism of water, including bottom plate and pcb board, the pcb board are fixed on bottom plate, the pcb board solid
Surely there is binding post, in addition to be set in the shell of pcb board, the shell is provided with the first mounting hole coordinated with binding post, institute
State and sealing-plug is provided with the first mounting hole, the sealing-plug is fitted between binding post and the first mounting hole.
It is preferred that, at least one raised small rib strip is offered on the inside of the sealing-plug.
It is preferred that, the outer back-up ring for tilting certain angle is provided with the outside of the sealing-plug, the outer back-up ring is tilted to upper end.
It is preferred that, be provided with limited step on the outside of the upper end of the sealing-plug, the upper end of first mounting hole be provided with
The groove that the limited step coordinates.
Compared with prior art, the utility model has the advantages that：
The waterproof problem around binding post can be solved, assembling is simple and cost is low, facilitates after-sales service, and can realize many
Weight waterproof improves the security of product and vehicle to improve the water resistance of product.
Brief description of the drawings
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is the sectional view of binding post proof mechanism of water of the present utility model.
Wherein, 1, bottom plate, 2, pcb board, 3, shell, 4, sealing-plug, 21, binding post, the 30, first mounting hole, the 31, first peace
Fill hole medial surface, 32, groove, 41, outer back-up ring, 42, raised small rib strip, 43, limited step.
Embodiment
To make the purpose of this utility model, technical scheme and advantage of greater clarity, with reference to embodiment
And referring to the drawings, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid not
Necessarily obscure concept of the present utility model.
Embodiment：
As shown in figure 1, a kind of binding post proof mechanism of water, including bottom plate 1 and pcb board 2, pcb board 2 is fixed on bottom plate 1,
One or more binding post 21 is fixed with pcb board 2, binding post 21 is used to connect high current wire, and binding post 21 is generally
Cylinder.The top of pcb board 2 is set with a shell 3, and shell 3 can cover pcb board, prevents water inlet in pcb board.Set on shell 3
The second mounting hole for installing other interfaces can also be set by having on the first mounting hole 30 coordinated with binding post 21, pcb board 2, this
Sample causes whole pcb board 2 to be covered in shell 3, only exposes the place with external connection.It is provided with first mounting hole 30 close
Blocking 4, sealing-plug 4 is fitted between the mounting hole 30 of binding post 21 and first.
As shown in Fig. 2 in order to further increase water resistance, the inner side of sealing-plug 4 offers at least one raised small rib strip
42.The outside of sealing-plug 4 is provided with the outer back-up ring 41 for tilting certain angle, and outer back-up ring 41 is tilted to upper end.Outside the upper end of sealing-plug 4
Side is provided with limited step 43, and the upper end of the first mounting hole 30 is provided with the groove 32 coordinated with limited step 43.
When sealing-plug 4 is inserted in the BUSBAR binding posts 21 on pcb board 2, the inner side small rib strip 42 of sealing-plug 4 and binding post 21
Laminating and compressive deformation realize on the inside of sealing, while the outer back-up ring 41 of sealing-plug 4 fitted with the first mounting hole medial surface 31 and
Sealing on the outside of compressive deformation realization, the outside of sealing-plug 4 is provided with formation after the compressive deformation of outer back-up ring 41 for tilting certain angle
It is inverse with installation direction, to reach the effect for preventing that sealing-plug 4 from coming off.The limited step 43 of sealing-plug 4 is attached to after installation
