Embodiment
Describe specific embodiments of the invention in detail below in conjunction with accompanying drawing.
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 the brush holder 210.This brush holder 210 comprises internal port, outside port and multilayer line, and wherein internal port 2 is meant the part that is connected of pin 231 with the multilayer line of chip 230, and outside port is meant the part that is connected of multilayer line and brush holder peripheral circuit outward.A plurality of outside ports have at length been showed among Fig. 2, comprise the outer end 221b that is connected with B+ port (battery positive voltage port), the outside port 223b that is 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 that is connected with the F+ port (the anodal port of the field power supply of generator) of peripheral circuit.As shown in Figure 2, said external port or be parallel to the XY plane or vertical XY plane is three-dimensional wrong attitude and distributes.
In the prior art, as shown in fig. 1, because what adopt is the integrated circuit of radiating shell packing forms, this chip 140 is positioned on the brush holder abreast, the pin 131 of its chip 140 vertically protrudes on this voltage regulator radiating shell, is connected with signal circuit with the power circuit of brush holder respectively by this pin 131.Chip 130 housings are fixed by the mode and the brush holder 110 of machinery or welding, in brush holder 110 internal placement number of metal circuit sheet 120 are arranged, and chip 130 is connected with the 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, replace the integrated circuit of expensive radiating shell packing forms with direct insertion chip.The difference of the integrated circuit of direct insertion chip and radiating shell packing forms is that direct insertion pin of chip is drawn from the one or more sides of packaged chip, is arranged in straight line, and promptly this direct insertion chip is the 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 is the distribution of 3D solid, and the existence of inside and outside end interface intersects.Therefore be provided with clover leaf with different levels multilayer line in the present embodiment, the interior end interface 2 of this multilayer line can be coupled with the chip pin 231 of plane distribution, and the other end then can be connected with the outer end excuse that solid distributes.This multilayer line comprises signals layer and power layer by the function branch, and wherein this signals layer is used to transmit weak electric signal, is connected with control circuit, and this power layer is used to transmit the forceful electric power signal, is connected with motor circuit.Power layer is further divided into power input layer and power output layer again.Signals layer 223, power input layer 221 and power output layer 222 lay respectively at different planes, the three does not spatially contact each other mutually, mutually insulated, but end interface 2 (end that promptly is connected with chip) all is positioned on the plane 290 in it, and welds 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 promptly interior end interface 2 of the part in the frame of broken lines among the figure.Should in 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 output layer inner port 222a and power output layer inner port 221a in the 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 the coupling of multilayer line on 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 how to realize by the understood in detail multilayer line 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 made up of a printed substrate 250.According to the designing requirement of control circuit, be set in advance layer of metal film on the surface of this printed substrate 250, this metal film has constituted signals layer 223.Simultaneously, this printed substrate 250 is provided with some through holes 251, and an end of power layer is fixed in one of them through hole 251.For the ease of installing and using, can be rectangle with this via design.Although therefore an end of signals layer, power layer is arranged in a crossed manner mutually, and connect in vertical peripheral circuit, the other end can be connected with the chip pin on plane.
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 bigger than pin 231 areas, is convenient to welding.Signals layer 223 is to form on printed substrate 250, according to the designing requirement of control circuit, has been set in advance the layer of metal film circuit in the position of regulation on the surface of this printed substrate 250, and this metal film constitutes signals layer 223.Usually, the control circuit of signals layer 223 is connected with P port 222b (phase signal port), DFM port (auxiliary port), the L port (charging indicator light port) of outer end interface.Printed circuit board (PCB) metal film circuit from the interior end interface 223a of chip pin 231 welding, on printed circuit board (PCB), extend to the P port (phase signal port) of signals layer outer end interface 223b.Power input layer 221 abuts against the no metal film zone of printed circuit board (PCB).Simultaneously power output layer 222 is positioned at the another side of printed circuit board (PCB), and the mode and the metal film region insulation of filling by injection moulding.Make metal film signals layer 223 and other layers circuit keep insulation like this, be injected into one with whole brush holder 210 again.
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.
