Wherein: a free end P1, a fixed end P2, a main line P3, a sub-line group P4, a sub-line P41 and a substrate P5.
Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1-2, a substrate device compatible with multiple chips includes a free end P1, a fixed end P2, a main circuit P3, a sub-circuit group P4 and a substrate P5;
the free end P1 is arranged on the plate surface of the substrate P5;
the fixed end P2 is arranged on the plate surface of the substrate P5;
the free end P1 is provided with N pins;
the fixed end P2 is provided with N pins;
the main lines P3 are disposed on the board surface of the substrate P5, and the number of the main lines P3 is N;
the secondary circuit groups P4 are disposed on the board surface of the substrate P5, and the number of the secondary circuit groups P4 is N;
each secondary line group P4 includes N secondary lines P41, and a switching device for switching on or off the secondary line P41 is provided on each secondary line P41;
the sub-lines P41 within each sub-line group P4 are arranged in parallel;
one end of each main line P3 is electrically connected to the pin uniquely corresponding to the main line P2, the other end of each main line P3 is electrically connected to the end of each sub line P41 in the sub line group P4 uniquely corresponding to the main line P3, and the other end of the sub line P41 in each sub line group P4 is electrically connected to the pin uniquely corresponding to the sub line in the free end P1.
In this embodiment, the free end P1 and the fixed end P2 are both wiring terminals, the number of N is 7, the free end P1 is connected to a color temperature chip capable of adjusting the color temperature of the lamp, that is, each pin of the color temperature chip is electrically connected to each pin of the free end P1; the fixed end P2 is connected to the switch power supply, that is, each pin of the switch power supply is electrically connected with each pin of the fixed end P2, and the fixed end P2 and each pin of the switch power supply are fixed and cannot be changed freely.
For example, after the fixed end P2 is connected to the switching power supply, each pin of the fixed end P2 represents a positive power supply terminal, a negative power supply terminal, a signal terminal, and a signal terminal of the switching power supply; since the signals represented by the pins of the color temperature chip are not necessarily in one-to-one correspondence with the signals represented by the pins of the switching power supply, after the color temperature chip is connected to the free end P1, the pins of the color temperature chip and the signals represented by the pins of the switching power supply can be in one-to-one correspondence by adjusting the on or off of the switching element on each of the sub-lines P41 in each of the sub-line groups P4.
The switching elements in the first sub-line group P4 from the left in the drawing are sequentially encoded by J1 to J7 from left to right, for example, pin 1 in the fixed end P2 is the positive power terminal, and if pin 1 of the free end P1 is also the positive power terminal at this time, the positive power terminal of the fixed end P2 can be corresponding to the positive power terminal of the free end P1 by turning on the switching element J1 and turning off the other six switching elements.
For another example, pin 1 in the fixed end P2 is the positive power terminal, and pin 5 of the free end P1 is the positive power terminal, so that the switch J5 needs to be turned on, and the remaining six switches are turned off, so that the positive power terminal of the fixed end P2 corresponds to the positive power terminal of the free end P1.
Therefore, through the substrate device of this application, can directly use different function chips on same style's switching power supply, and need not change switching power supply's PCB circuit board to reduce research and development cost, improved production efficiency.
Further, the substrate P5 is a PCB.
Errors of wiring and assembly can be greatly reduced, and the automation level and the production labor rate are improved.
Further, the switch is a 0 ohm resistor.
The use of the 0 ohm resistor chip resistor for conducting and disconnecting the secondary line P41 is less costly and more efficient, because the chip 0 ohm resistor is usually assembled by a machine, the assembly speed is faster, and the 0 ohm resistor is small in size, which makes the overall size of the substrate device smaller by using the 0 ohm resistor.
Further, the switch piece is a jumper wire.
The on and off of the sub-line P41 can also be realized using a jumper.
Further, the switch member is a dial switch.
The on and off of the sub line P41 can be realized also using a dial switch.
Further, the free end P1 includes at least 1 spare pin in addition to the N pins.
The spare pin is not connected with the main line P3 and the auxiliary line P41, a spare pin is reserved, the spare pin is convenient to use when needed in follow-up, and the No. 8 pin of the P1 in the embodiment is the spare pin.
Further, the fixed end P2 includes at least 1 spare pin besides N pins.
The spare pin is not connected with the main line P3 and the auxiliary line P41, a spare pin is reserved, the spare pin is convenient to use when needed in follow-up, and the No. 8 pin of the P2 in the embodiment is the spare pin.
Further, the number of N is 7.
Meets the pin position requirement of the conventional mainstream chip.
