Abstract
The invention discloses a binding post fixing mechanism, which comprises a bottom plate and a PCB, wherein the PCB is fixed on the bottom plate; a binding post is fixed on the PCB; the binding post and the PCB are in snap-fit connection; and a plurality of auxiliary holes are arranged in the junction of the binding post on the PCB. The binding post fixing mechanism is simple in structure and low in cost, reliable fixation of the binding post and the PCB can be achieved and the phenomena of looseness and the like are avoided.
Description
Technical field
The present invention relates to a kind of binding post fixed mechanism, more particularly to a kind of binding post suitable for controller for electric vehicle
Fixed mechanism.
Background technology
Electric motor car is the car with electric power as the energy, with the reinforcement of people's environmental consciousness, electric motor car with electric power to drive
One of important vehicles of people's go off daily are become.Electric motor car as one of three big core component of electric motor car is controlled
Device, its reliable, security play vital effect against the quality of car load.
The lead way of output being adopted existing controller for electric vehicle High-current output, controller lead is by controller for electric vehicle more
PCB draws, 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 usually leans on screw lock in circuit board
On, the contact resistance between relatively costly and two contact surfaces of this electrical connection is larger, and easily heating causes the energy of high current
Power is limited, and will so affect performance and the life-span of controller, so that damaging controller, to affect the safety of vehicle.
For example, Chinese patent literature CN 205543316 discloses a kind of binding post, and which includes controller housing, aluminium base
Pcb board and binding post, link post on aluminum base PCB plate, binding post include binding post base and wiring cylinder, binding post bottom
Seat two ends are provided with attachment screw, and attachment screw passes through aluminum base PCB plate and is tightened on controller drain pan；In the middle part of binding post base
Wiring cylinder is provided with, 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
When making, caloric value is big, has a strong impact on performance and the life-span of controller.
The content of the invention
In order to solve contact laminating of the current binding post with pcb board not tightly, caloric value big problem when high current works, this
Goal of the invention is：A kind of binding post fixed mechanism is provided, it is simple structure, with low cost, it is possible to achieve binding post can with pcb board
By fixation, it is to avoid the phenomenons such as loosening occur.
The technical scheme is that：
A kind of binding post fixed mechanism, including base plate and pcb board, the pcb board are fixed on base plate, are fixed with the pcb board
Binding post, the binding post are provided with multiple via holes with binding post joint on the pcb board with pcb board to snap connection.
Preferably, the binding post lower end is provided with least one card base, arranges with binding post joint on the pcb board
There is location hole, the card base is connected by interference fit with location hole.
Preferably, the location hole is two, and the card base is square card base, and the via hole is uniformly arranged on location hole
Periphery.
Preferably, diameter of the diameter of the via hole less than location hole.
Compared with prior art, it is an advantage of the invention that：
Binding post and pcb board are to snap connection, it is possible to achieve both is brought into close contact, and on pcb board with binding post joint
Be provided with multiple via holes, then the special welding by wave-soldering so that scolding tin can pass through location hole and via hole fully on arrive
The surface of binding post, realizes that the reliability that binding post is also reached while reliable electrical connection is fixed.Present configuration is simple, into
Originally it is cheap, it is possible to achieve binding post is fixed with the reliability of pcb board, it is to avoid the phenomenons such as loosening occur.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the structural representation of the binding post fixed mechanism of the present invention.
Wherein, 1, base plate, 2, pcb board, 3, binding post, 21, location hole, 22, via hole, 23, lower composition surface, 31, card base,
32nd, upper composition surface.
Specific embodiment
To make the object, technical solutions and advantages of the present invention of greater clarity, with reference to specific embodiment and join
According to accompanying drawing, the present invention is described in more detail.It should be understood that these descriptions are simply exemplary, and it is not intended to limit this
Bright scope.Additionally, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring this
The concept of invention.
Embodiment：
As shown in figure 1, a kind of binding post fixed mechanism, including base plate 1 and pcb board 2, pcb board 2 is fixed on base plate 1, on pcb board 2
Edge 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, 3 lower end of binding post 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 on pcb board 2, is provided with binding post joint
Unanimously, card base 31 is connected up to fastening by interference fit with location hole 21 and connects binding post 3, the now upper engagement of binding post lower end
Fit 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 location hole 21.The diameter of via hole 22 is more preferably less than the diameter of location hole 21.By the special of wave-soldering
Welding so that scolding tin can pass through location hole 21 and the fully upper surface to binding post 3 of via hole 22, realize reliable electrical connection
While also reach binding post 3 reliability it is fixed.
It should be appreciated that the above-mentioned specific embodiment of the present invention is used only for exemplary illustration or explains the present invention's
Principle, and be not construed as limiting the invention.Therefore, that what is done in the case of without departing from the spirit and scope of the present invention is any
