Description
Technical field
The utility model relates to metallic printed circuit board installation busbar in vehicle, particularly relates to a kind of metallic printed circuit board installation busbar with the structure of the pull-out capacity that can improve between metallic printed circuit board.
Background technology
The environment-friendly vehicle such as electric motor car, hybrid electric vehicle take electricity as power source, therefore by motor, inverter, current transformer, battery, onboard charger (Onboardcharger; Etc. OBC) multiple electronic unit is formed.
As mentioned above, electric motor car, hybrid electric vehicle are provided with multiple electrical and electronic parts, therefore use a large amount of printed circuit board (PCB) (PrintedCircuitBoard; PCB) these electrical and electronic parts of electric control.
These parts major parts are all conversion elements, produce large calorimetric during power consumption, therefore in order to the metallic printed circuit board (MetalPCB) adopting and formed by metal in PCB that dispels the heat.
Metallic printed circuit board is made up of metallic conductor, therefore has the insulating barrier preventing from being energized.
Therefore, when to metallic printed circuit board soldering of electronic components, when passing hole is welded to printed circuit board (PCB), insulating barrier is easily damaged, therefore cannot utilize plug-in type (DipType) element, patch-type (SMDType) element needing face of weld can only be used.Therefore, the method in the face of face and the printed circuit board (PCB) contacted with printed circuit board (PCB) in soldered elements is adopted.
In addition, it is mechanical energy or the relay playing adverse effect by current conversion that electric motor car or hybrid electric vehicle need a large amount of, therefore in order to these relay transmission currents to its local in conjunction with busbar.
Busbar (Busbar) is the conductor of Low ESR, high current capacity, can connect plural circuit or intrasystem multiple isocenter (LikePoint) respectively.Busbar is typically used as the common conductor to multiple supply power supply.
Fig. 1 display is according to the structure metallic printed circuit board of prior art being provided with busbar, and Fig. 2 (a), Fig. 2 (b) show the welding region of metallic printed circuit board in structure shown in Fig. 1 and busbar.
Structure shown in Fig. 1 be busbar 2,3 be arranged on form hybrid electric vehicle the metallic printed circuit board of low-voltage direct-direct current transducer (LDC) and diode panel 1 on form, diode input busbar 2-1,2-2 and diode ground connection busbar 3 are arranged on diode panel 1.
Diode input busbar 2-1,2-2 are for connecting secondary side and the diode panel 1 of the transformer being positioned at LDC, and diode ground connection busbar 3 is for connecting shell and the diode panel 1 of LDC.
As above, when as when the diode panel 1 of metallic printed circuit board being installed busbar 2,3 as shown in Fig. 2 (a), Fig. 2 (b), diode panel 1 is limited to a-quadrant and B region with the welding region of busbar.
That is, be not weld metal printed circuit board (PCB) and busbar whole contact-making surface when weld metal printed circuit board (PCB) and busbar, but only weld very little region, the pull-out capacity therefore between metallic printed circuit board and busbar is very low.Pull-out capacity refers to that busbar is bonded in the power on metallic printed circuit board firmly.
As mentioned above, be be arranged on metallic printed circuit board with welding manner by busbar now, when therefore bonding area is little, pull-out capacity is not enough, when being given a shock or applying screw assembling torque, may be there is crackle or come off in welding position, reliability decrease.
When needing to be energized by busbar, if welding position comes off, then owing to being energized, the dangerous situation that vehicle stops may being caused.
Especially, these parts all will be used for automobile, therefore must can bear fierce vibration and severe environmental conditions, and if pull-out capacity is not enough, then cannot ensure the combination of busbar and metallic printed circuit board, therefore product reliability and fail safe are very low.
