Description
Technical field
The utility model is related to a kind of binding post fixed mechanism, more particularly to a kind of connecing suitable for controller for electric vehicle
Terminal fixed mechanism.
Background technology
Electric car is using electric power as driving, using electric power as the car of the energy, with the reinforcement of people's environmental consciousness, electric car
Turn into one of important vehicles of people's go off daily.Controlled as the electric car of one of the big core component of electric car three
Device, its reliable, security plays vital effect against the quality of vehicle.
The lead way of output being used existing controller for electric vehicle High-current output, controller lead is by controller for electric vehicle more
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 cost of this electrical connection is higher and two contact surfaces between contact resistance it is larger, easily heating to walk the energy of high current
Power is limited, and will so be influenceed performance and the life-span of controller, so that damaging controller, is influenceed the safety of vehicle.
For example, Chinese patent literature CN 205543316 discloses a kind of binding post, it includes controller housing, aluminium base
Link post on pcb board and binding post, aluminum base PCB plate, binding post includes binding post base and wiring cylinder, binding post bottom
Seat two ends are provided with attachment screw, and attachment screw is through aluminum base PCB plate and is tightened on controller drain pan；In the middle part of binding post base
Provided with wiring cylinder, controller upper shell is stretched out in wiring cylinder upper end, and wiring cylinder upper end connects terminals by trip bolt
Son.Binding post is fixed by screws on pcb board, and the contact resistance between both contact surfaces is larger so that in normal high current work
Caloric value is big when making, and has a strong impact on performance and the life-span of controller.
Utility model content
In order to solve current binding post with pcb board contact laminating it is not tight, high current work when caloric value it is big the problem of, this
Utility model purpose is：A kind of binding post fixed mechanism is provided, it is simple in construction, with low cost, it is possible to achieve binding post and pcb board
Reliable fixation, it is to avoid the phenomenon such as occur loosening.
The technical solution of the utility model is：
A kind of binding post fixed mechanism, including bottom plate and pcb board, the pcb board are fixed on bottom plate, the pcb board solid
Surely there is a binding post, the binding post is provided with binding post joint multiple auxiliary with pcb board to snap connection, on the pcb board
Help hole.
It is preferred that, the binding post lower end is provided with least one card base, the pcb board to be set with binding post joint
There is positioning hole, the card base is connected with positioning hole by interference fit.
It is preferred that, the positioning hole is two, and the card base is square card base, and the via hole is uniformly arranged on positioning hole
Periphery.
It is preferred that, the diameter of the via hole is less than the diameter of positioning hole.
Compared with prior art, the utility model has the advantages that：
Binding post is to snap connection with pcb board, it is possible to achieve both is brought into close contact, and is connect on pcb board with binding post
Multiple via holes, then the special welding for passing through wave-soldering are provided with conjunction so that scolding tin can be abundant by positioning hole and via hole
The upper surface to binding post, also reaches the reliable fixation of binding post while realizing reliable electrical connection.The utility model knot
Structure is simple, with low cost, it is possible to achieve the reliable fixation of binding post and pcb board, it is to avoid the phenomenon such as occur loosening.
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 structural representation of binding post fixed mechanism of the present utility model.
Wherein, 1, bottom plate, 2, pcb board, 3, binding post, 21, positioning hole, 22, via hole, 23, lower composition surface, 31, card base,
32nd, upper composition surface.
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 fixed mechanism, including bottom plate 1 and pcb board 2, pcb board 2 is fixed on bottom plate 1, PCB
The upper edge of plate 2 is fixed with one or more binding post 3, and binding post 3 is to snap connection with pcb board 2.
As shown in Fig. 2 preferably snapping connection mode for one kind, the lower end of binding post 3 is provided with least one square card base
31（The present embodiment is two）, the quantity of circular locating openings 21, quantity and card base is provided with pcb board 2 with binding post joint
Unanimously, card base 31 is connected up to fastening by interference fit with positioning hole 21 and connects binding post 3, the now upper engagement of binding post lower end
Fitted with the lower composition surface 23 of pcb board in face 32.Lower composition surface 23 on pcb board 2 is provided with multiple via holes 22, and via hole 22 is equal
The even periphery for being arranged on positioning hole 21.The diameter of via hole 22 is more preferably less than the diameter of positioning hole 21.Pass through the special of wave-soldering
Welding so that scolding tin can realize reliable electrical connection by positioning hole 21 and the fully upper surface to binding post 3 of via hole 22
While also reach the reliable fixation of binding post 3.
It should be appreciated that above-mentioned embodiment of the present utility model is used only for exemplary illustration or explains this reality
With new principle, without constituting to limitation of the present utility model.Therefore, without departing from spirit and scope of the present utility model
In the case of any modification, equivalent substitution and improvements done etc., should be included within protection domain of the present utility model.In addition,
The utility model appended claims are intended to fall into scope and border or this scope and border
