Abstract
The utility model provides a kind of high current system export structure, which is characterized in that the output of Switching Power Supply walks high current using copper bar, and traditional power module is replaced to export direct insertion metal needle, walks the frame mode of electric current 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 radiate, and improves the reliability of power supply.
Description
Technical field
The utility model is related to field of switch power, more particularly to a kind of high current system export structure.
Background technology
Be on the rise with the anxiety and environmental pollution of global energy supply, clean energy vehicle-electric vehicle by
Step is paid attention to by various countries, and especially in recent years, electric vehicle is flourished, high power vehicular controller, DC/DC
Converter, OBC promote Power Electronic Technique large-scale use on automotive electronics.Due to the use environment that automotive electronics is harsh,
To high efficiency, high power density, high reliability proposes higher requirement, in this context, if opened also according to traditional
Powered-down source output uses direct insertion PIN needle, first PIN needle to be heated because bearing big electric current, and can be carbonized discoloration, on the other hand,
For PIN on the PCB of client, PCB has to be made thickness to meet heat dissipation, also considerably increases cost of manufacture in this way.
To solve the above-mentioned problems, for the vehicle power supply module of high current, the utility model proposes a kind of outputs to use
The frame mode of copper bar.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of high current system export structures.
The utility model is to solve above-mentioned technical problem by following technical proposals:
A kind of high current system export structure, which is characterized in that the output of Switching Power Supply walks high current using copper bar, substitution
Traditional power module exports direct insertion metal needle, walks the frame mode of electric current with circuit board in client.
Preferably, above-mentioned high current system export structure, which is characterized in that the output of Switching Power Supply is just negative with two with output
A copper post welding is on circuit boards.
Preferably, above-mentioned high current system export structure, which is characterized in that there are two above hole on copper bar, hole it is big
It is mating less than with copper post.
Preferably, above-mentioned high current system export structure, which is characterized in that one end of copper bar passes through a hole on copper bar
It is fixed in copper post with nut, the other end is fixed in the equipment of client, and copper bar can be used for a power module, also may be used
So that two power modules in parallel use.
The utility model 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, copper bar can preferably radiate, and improve the reliability of power supply, be new-energy automobile
Development contribute.

Specific embodiment
The utility model preferred embodiment is provided below in conjunction with the accompanying drawings, the technical solution of the utility model is described in detail.
The utility model provides a kind of high current system export structure, as shown in Figure 1, being welded with two on power module 01
Copper post, copper post 03 is to export just here, and copper post 04 is that output is negative, in Fig. 2 02 be power module side view, it can be seen that copper post
Bottom have the bottom of multiple small thin PIN to PCB, this is done to eat the welding surface of copper post, tin area is big, and copper post can
To be firmly welded on pcb board.05 is the top view for exporting positive copper bar in Fig. 3, and 06 is the side view for exporting positive copper bar in Fig. 4
Scheme, 07 is the right view for exporting positive copper bar in Fig. 5.08 is that power module exports the top view for bearing copper bar in Fig. 6, and 09 is in Fig. 7
The side view of copper bar is born in power module output, and 10 be that power module exports the right view for bearing copper bar in Fig. 8.It can from 05 and 08
The aperture of 2 or more is had on to copper bar, the size and copper post in hole are mating, and copper bar is fixed on nut in copper post by aperture.
The aperture for having 2 or more on copper bar is in order to which module can be used in parallel, as shown in Figure 9.This export structure not only saves
The high cost of multilayer heavy copper circuit board, and in structure space without apparent increased, copper bar can preferably dissipate
Heat improves the reliability of vehicle power supply.
Although the foregoing describe the specific implementation case of the utility model, it will be appreciated by those of skill in the art that
These are merely examples, and under the premise of the principle and essence without departing substantially from the utility model, these case study on implementation can be done
Go out various changes or modifications.Therefore, the scope of protection of the utility model is defined by the appended claims.
