Below in conjunction with accompanying drawing, describe specific embodiments of the invention in detail.
Voltage regulator brush holder assembly provided by the present invention, comprises chip and brush holder.Its embodiment please refer to Fig. 2.This voltage regulator brush holder assembly comprises chip 230 and brush holder 210, and its chips 230 is fixed on brush holder 210.This brush holder 210 comprises internal port, outside port and multilayer line, and wherein internal port 2 refers to the part that is connected of pin 231 with the multilayer line of chip 230, and outside port refers to the part that is connected of multilayer line and peripheral circuit outside brush holder.A plurality of outside ports in Fig. 2, have at length been shown, comprise the outside port 221b being connected with B+ port (battery positive voltage port), the outside port 223b being connected with L port (charging indicator light port), DFM port (generator working state signal output), the P port (phase coil signal port) of peripheral circuit, the outside port 222b being connected with the F+ port (the anodal port of field power supply of generator) of peripheral circuit.As shown in Figure 2, said external port or be parallel to XY plane or vertical XY plane, is three-dimensional wrong state and distributes.
In prior art, as shown in fig. 1, due to what adopt, it is the integrated circuit of radiating shell packing forms, this chip 140 is positioned on brush holder abreast, the pin 131 of its chip 140 vertically protrudes from this voltage regulator radiating shell, by this pin 131, is connected respectively with the power circuit of brush holder with signal circuit.Chip 130 housings are fixed by mode and the brush holder 110 of machinery or welding, in brush holder 110 internal placement, have some metallic circuit sheets 120, and chip 130 is connected with brush holder external circuit by metallic circuit sheet 120.In the present invention, in order to reduce the total cost of voltage regulator brush holder assembly, with direct insertion chip, replace the integrated circuit of expensive radiating shell packing forms.The difference of the integrated circuit of direct insertion chip and radiating shell packing forms is, the pin of direct insertion chip is drawn from the one or more sides of packaged chip, is arranged in straight line, and this direct insertion chip is 2D floor plan.Because the pin 231 of this chip 230 is to distribute along plane and straight line, and the circuit of the miscellaneous part of generator three-dimensional distribution that be 3D, and inside and outside end interface exists and intersects.Therefore be provided with in the present embodiment clover leaf with different levels multilayer line, the interior end interface 2 of this multilayer line can be coupled with the chip pin 231 of plane distribution, and the other end can be connected with the outer end interface that solid distributes.This multilayer line divides and comprises signals layer and power layer by function, and wherein this signals layer is used for transmitting weak electric signal, is connected with control circuit, and this power layer is used for transmitting forceful electric power signal, is connected with motor circuit.Power layer is further divided into again power input layer and power stage layer.Signals layer 223, power input layer 221 and power stage layer 222 lay respectively at different planes, three does not spatially contact each other mutually, mutually insulated, but one end that in it, end interface 2(is connected with chip) be all positioned in a plane 290, and weld mutually with the pin 231 of chip 230 on this coupling surface 290.
Fig. 3 is the part B-B generalized section of voltage regulator brush holder assembly involved in the present invention, has elaborated the distribution situation of interior end interface in Fig. 3.As shown in Figure 3, the interior end interface 2 of the part in dotted line frame in figure.This interior end interface 2 comprise altogether with the interface of multilayer line and with the interface of earth terminal 290.Interior end interface 2 comprises successively: end interface 223a, ground connection inner port 229a, power stage layer inner port 222a and power stage layer inner port 221a in signals layer.Above-mentioned inner port is by contacting with the upper and lower surface of chip pin 231 at the same time or separately, thereby realizes multilayer line in the coupling of a plane.
Fig. 4 is the A-A generalized section of voltage regulator brush holder assembly involved in the present invention, and Fig. 5 is the local amplification view of the multilayer line of voltage regulator brush holder assembly involved in the present invention, can understand in detail multilayer line how to realize by Fig. 4 and Fig. 5.As shown in Figure 4, chip 230 is placed the inside with this voltage regulator brush holder assembly 200, and its pin 231 is parallel to horizontal plane.In the present embodiment, this coupling plane and signals layer 223 are in the same plane.The signals layer 223 of this voltage regulator brush holder assembly is comprised of a printed substrate 250.On the surface of this printed substrate 250, according to the designing requirement of control circuit, be pre-arranged layer of metal film, this metal film has formed signals layer 223.Meanwhile, be provided with some through holes 251 on this printed substrate 250, one end of power layer is fixed in one of them through hole 251.For the ease of installing and using, can be rectangle by this via design.Although therefore one end of signals layer, power layer is mutually arranged in a crossed manner, and connect in vertical peripheral circuit, the other end can be connected with the chip pin of plane.
Power stage layer 222 is to be an electric conductor, is preferably a sheet metal.The outer end interface 222b of power stage layer 222 is connected with peripheral circuit, and other end 222a is placed in the opening of printed circuit board (PCB) 250.The internal port 222a of power stage layer 222 is designed to a shape with groove 244.When the pin 231 of chip 230 is connected with power stage layer internal port 222a, pin 231 is pushed in the middle of groove 244, pin 231 is subject to the extruding of upper end 241, forces pin 231 to be fixed between 241Yu lower end, upper end, and also therefore pin 231 links together with power stage layer 222.Similarly, can also adopt another execution mode, the headspace that is about to groove 244 increases, and using it as a scolder storage cave.Can keep being equally like this connected of pin 231 and power stage layer 222.
In like manner, because a plurality of board openings are all in the same plane, power input layer 221 can be connected in the same way with pin 231.
The printed circuit board (PCB) metal film of signal port 233a directly contacts with chip pin 231, and metal film is larger than pin 231 areas, is convenient to welding.Signals layer 223 is to form on printed substrate 250, on the surface of this printed substrate 250, according to the designing requirement of control circuit, in the position of regulation, has been pre-arranged layer of metal film circuit, and this metal film forms signals layer 223.Typically, the P port 222b(phase signal port of the control circuit of signals layer 223 and outer end interface), DFM port (auxiliary port), L port (charging indicator light port) are connected.Printed circuit board (PCB) metal film circuit, from the interior end interface 223a with chip pin 231 welding, extends to the P port (phase signal port) of signals layer outer end interface 223b on printed circuit board (PCB).Power input layer 221 abut against printed circuit board (PCB) without metal film region.Power stage layer 222 is positioned at the another side of printed circuit board (PCB) simultaneously, and by mode and the metal film region insulation of mould filling.Make like this metal film signals layer 223 and other layer of circuit keep insulation, then be injected into one with whole brush holder 210.
Described in this specification is preferred embodiment of the present invention, and above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art, all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
