Abstract
The present invention provides a kind of high current system export structure, it is characterised in that the output of Switching Power Supply walks high current using copper bar, replaces traditional power module output to use direct insertion metal needle, the frame mode of electric current is walked with circuit board in client.This structure, saves the high cost of multilayer heavy copper circuit board, meanwhile, structure space is not significantly increased, and copper bar is more conducive to radiating, improves the reliability of power supply.
Description
Technical field
The present invention relates to field of switch power, more particularly to a kind of high current system export structure.
Background technology
The anxiety and environmental pollution supplied with global energy are on the rise, clean energy vehicle-electric automobile by
Step is paid attention to by various countries, and especially in recent years, electric automobile is flourished, high power vehicular controller, and DC/DC becomes
Parallel operation, OBC promotes Power Electronic Technique large-scale use on automotive electronics.It is right due to the use environment that automotive electronics is harsh
High efficiency, high power density, high reliability proposes higher requirement, in this context, if also according to traditional switch
Power supply output uses direct insertion PIN needle, first PIN needle and is heated because bearing big electric current, and can be carbonized discoloration, on the other hand, PIN
On the PCB of client, PCB has to be made thickness to meet radiating, so also considerably increases cost of manufacture.
In order to solve the above problems, for the vehicle power module of high current, the present invention proposes that a kind of output uses copper bar
Frame mode.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of high current system export structure.
The present invention is to solve above-mentioned technical problem by following technical proposals：
A kind of high current system export structure, it is characterised in that the output of Switching Power Supply walks high current, substitution tradition using copper bar
Power module output use direct insertion metal needle, the frame mode of electric current is walked with circuit board in client.
Preferably, above-mentioned high current system export structure, it is characterised in that the output of Switching Power Supply is just born with output and uses two
Individual copper post welding is on circuit boards.
Preferably, above-mentioned high current system export structure, it is characterised in that have more than two holes on copper bar, hole it is big
It is supporting less than with copper post.
Preferably, above-mentioned high current system export structure, it is characterised in that one end of copper bar passes through a hole on copper bar
It is fixed on nut in copper post, the other end is fixed in the equipment of client, copper bar can be used for a power module, also may be used
So that two power modules in parallel are used.
The present invention provides a kind of high current system export structure, saves the high cost of multilayer heavy copper circuit board, meanwhile,
Structure space is not significantly increased, and copper bar can preferably radiate, and improves the reliability of power supply, is the development of new-energy automobile
Contribute.
Brief description of the drawings
Fig. 1 is power module top view and side view of the output equipped with copper post.
Fig. 2 is the top view of copper bar, side view and right view.
Fig. 3 is the top view that two parallel modules use copper bar.
Embodiment
Present pre-ferred embodiments are provided below in conjunction with the accompanying drawings, to describe technical scheme in detail.
The present invention provides a kind of high current system export structure, as shown in figure 1, being welded with two copper on power module 01
Post, copper post 03 is to export just here, and copper post 04 is that output is negative, and 02 is the side view of power module, it can be seen that the bottom of copper post
There is multiple small thin PIN to PCB bottom, so doing things in order to which the solder side of copper post is eaten, tin area is big, and copper post can be firm
Be welded on pcb board.Fig. 2 is two copper bars used in power module output positive and negative, and 05 is the top for exporting copper bar just used
View, 06 is the side view for exporting copper bar just used, and 07 is the right view for exporting copper bar just used.08,09,10 is power supply respectively
The top view of the negative copper bar used of module output, side view and right view.Have the aperture of more than 2 on copper bar, the size in hole with
Copper post is supporting, and copper bar is fixed in copper post by aperture with nut.The aperture for having more than 2 on copper bar is in order to which module can be with
It is used in parallel, as shown in Figure 3.This export structure not only saves the high cost of multilayer heavy copper circuit board, and in structure
Space is without in the case of substantially increased, and copper bar can preferably radiate, and improve the reliability of vehicle power.
Although the foregoing describing the specific implementation case of the present invention, it will be appreciated by those of skill in the art that these
It is merely illustrative of, on the premise of the principle and essence without departing substantially from the present invention, a variety of changes can be made to these case study on implementation
More or modification.Therefore, protection scope of the present invention is defined by the appended claims.
