For example, FIG. 1 shows two possible types of microcontrollers, where U1 is the first microcontroller and U2 is the second microcontroller, which may be used in the manufacturing process. As shown in fig. 1, the pin 2 of U1 functions as VCC and the pin 26 functions as GND; the 2 nd pin of U2 is GND and the 26 nd pin is VCC. Due to the difference in pin functions of the two microcontrollers, the VCC circuit and the GND circuit on the circuit board are connected separately according to whether the selected microcontroller is U1 or U2. Therefore, the circuits on the circuit boards to which the U1 and the U2 are respectively adapted are different, i.e., the U1 and the U2 are used on different circuit boards. Therefore, if in some practical applications the microcontroller needs to be replaced, the U1 cannot be directly replaced by U2, the U2 cannot be directly replaced by U1, and the circuit board needs to be changed accordingly, so that the universality is poor, and the cost is increased.

It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.

The following detailed description is to be read in connection with specific embodiments.

First, the utility model discloses a general circuit for electronic component assembly.

Fig. 2 shows a general circuit for electronic component mounting according to a preferred embodiment of the present invention. In particular, the problem that the microcontroller chip cannot be replaced is solved by arranging a temporary jumper wire for the condition that the functions of the microcontrollers of different models/brands can be exchanged for pins with fixed positions, such as the pin 2 and the pin 26. It should be noted that the circuit shown in fig. 2 is not the final product form. For illustrative purposes, the specific configuration of the microcontroller U3 to be assembled and the general circuitry prior to installation of the microcontroller U3 is shown in FIG. 2. In this embodiment, the microcontroller U3 has a predetermined number of pins (e.g., 28), and the pins whose functions can be switched are fixed in position among all the pins of the microcontroller U3, i.e., fixed as the 2 nd pin and the 26 th pin, but not as pins in other positions (e.g., the 5 th pin).

As shown in fig. 2, VCC and GND denote respective circuit board function circuits, VCC denotes a power supply circuit, and GND denotes a ground circuit. The microcontroller U3 shown in fig. 2 may be a first type of microcontroller U3, i.e., may be configured to: pin 2 is a power supply pin and pin 26 is a ground pin. Of course, the microcontroller U3 shown in fig. 2 may also be a second type of microcontroller U3, i.e., may be configured to: the 2 nd pin is a ground pin and the 26 nd pin is a power pin.

With continued reference to fig. 2, L1, L2, L3, and L4 are temporary jumpers having two ends, denoted as 1-end (also referred to as non-common end) and 2-end (also referred to as common end). The 1 end of L1 is connected to VCC function circuit, and the 2 end of L1 is connected to the 26 th pin of microcontroller U3. The 1 end of the L2 is connected to the GND functional circuit, and the 2 end of the L2 and the 2 end of the L1 are connected to the 26 th pin of the microcontroller U3 together. Terminal 1 of L3 is connected to VCC functional circuit, and terminal 2 of L3 is connected to pin 2 of microcontroller U3. The 1 terminal of the L4 is connected to the GND function circuit, and the 2 terminal of the L4 and the 2 terminal of the L3 are connected together to the 2 nd pin of the microcontroller U3.

Therefore, when the microcontroller U3 is of the first model, i.e., pin 2 is VCC function and pin 26 is GND function, the circuit retains the L3 jumper and the L2 jumper and removes the L1 jumper and the L4 jumper when the microcontroller U3 of that model is assembled into the general circuit.

When another microcontroller is exchanged, for example, when the microcontroller U3 is of the second type, i.e., pin 2 is GND-capable and pin 26 is VCC-capable, the L1 jumper and the L4 jumper are reserved, and the L3 jumper and the L2 jumper are removed.

According to the technical scheme of the utility model, can select microcontroller comparatively freely, when a section microcontroller is out of stock, need not change the circuit board, as long as keep or remove this kind of interim wire jumper of L1, L2, L3 and L4 as required, just can replace the microcontroller of other not out of stock. That is, on the circuit board, the required respective function circuits have been arranged in advance, the mounting position of the microcontroller and the terminal positions of the plurality of jumper wires are fixed, the positions of the function-switchable pins on the microcontroller are also fixed, and after the microcontroller is mounted on the circuit board, it is only necessary to selectively connect the jumper wire terminals according to the pin functions of the microcontroller.

In the embodiment shown in fig. 2, by arranging jumpers (the jumpers have at least two ends), that is, a plurality of connection ends for connecting the jumpers are arranged on the circuit board, the jumpers have common ends connected together, the connection ends of the common ends are respectively connected to the pins of the electronic components, and the connection ends of the non-common ends are used for connecting to corresponding functional circuits. These functional pins connected to the respective functional circuits by jumpers are also referred to herein as jumper pins.

It is understood that the above case where the VCC function and the GND function are exchanged between the same pair of pins of different microcontrollers is only a specific example where the pin functions of the electronic components can be exchanged, and other function exchanges may also be similarly designed. Thus, the specific example shown in fig. 2 is merely a specific implementation of a circuit configuration for a general circuit for electronic component mounting, which is shown in fig. 3.

Next, referring to fig. 3, the universal circuit 100 is a universal circuit for electronic component mounting in which an electronic component 40 has a predetermined number of pins, the electronic component 40 has two jumper pins whose functions are exchangeable between electronic components of different models/brands, that is, a first jumper pin 41 and a second jumper pin 42 (for example, a ground pin and a power pin), and the positions of the first jumper pin 41 and the second jumper pin 42 among all the pins of the electronic component 40 are fixed. The universal circuit 100 further includes a first element connection terminal 51 (which may be understood as the common terminal of jumpers L1 and L2 in fig. 2) and a second element connection terminal 52 (which may be understood as the common terminal of jumpers L3 and L4), the first element connection terminal 51 being connected to the first jumper pin 41, and the second element connection terminal 52 being connected to the second jumper pin 42. The generic circuit 100 further comprises a first sub-circuit 10 (which may be understood as a power supply circuit) and a second sub-circuit 20 (which may be understood as a ground circuit) for performing a first function (correspondingly, a power supply function) and a second function (correspondingly, a ground function), respectively. The first sub-circuit 10 has a first circuit connection terminal 31 (which may be understood as the non-common terminal of jumper L3 and jumper L1 in fig. 2) and the second sub-circuit 20 has a second circuit connection terminal 32 (which may be understood as the non-common terminal of jumper L2 and jumper L4 in fig. 2). The first circuit connection terminal 31 is for selectively connecting to one of the first element connection terminal 51 and the second element connection terminal 52 according to a pin function of the electronic element 40. Second circuit connector 32 is for selectively connecting to the other of first element connector 51 and second element connector 52 in accordance with the pin function of electronic element 40.

In the circuit shown in fig. 3, in the case where the first jumper pin 41 matches the first function and the second jumper pin 42 matches the second function, the first element connection terminal 51 is coupled to the first circuit connection terminal 31 so that the first sub-circuit 10 is connected to the first jumper pin 41, and the second element connection terminal 52 is coupled to the second circuit connection terminal 32 so that the second sub-circuit 20 is connected to the second jumper pin 42.

In the circuit shown in fig. 3, when the first jumper pin 41 matches the second function and the second jumper pin 42 matches the first function, the first element connection terminal 51 is coupled to the second circuit connection terminal 32 so that the second sub-circuit 20 is connected to the first jumper pin 41, and the second element connection terminal 52 is coupled to the first circuit connection terminal 31 so that the first sub-circuit 10 is connected to the second jumper pin 42.

In the circuit shown in fig. 3, the first element connection terminal 51 and the second element connection terminal 52 may be electrically coupled to the first circuit connection terminal 31 and the second circuit connection terminal 32 through various forms of wires, jumper elements, logic switches, functional circuits, and the like.

It will be appreciated that the functionality of the pins of different models/brands of electronic components may be exchanged not only between two functions, but also between more functions, such as N (N ≧ 2, e.g., N3, 4, 5, etc., even up to all pins of the microcontroller chip, e.g., all 16 pins, 24 pins, 32 pins, etc.). For example, when N is 3, the jumper pins may be the 3 rd pin, the 4 th pin, and the 5 th pin on the left side of the microcontroller.

It should be understood that once the pin count of the microcontroller and the pins at which positions are selected as the pins for the jumper, the circuit board is designed correspondingly, i.e. the component connection terminals and the circuit connection terminals are arranged correspondingly. In other words, when the functions of the N jumper pins at the fixed positions of the microcontrollers of different models/brands are exchangeable on the premise that the microcontrollers have a predetermined number of pins, the general circuit for microcontroller assembly includes N element connection terminals and N sub-circuits according to the aforementioned design concept. The N element connecting ends are respectively used for being connected to N pins for wire jumping of the microcontroller, the N sub-circuits are respectively used for realizing N functions, the N sub-circuits are respectively provided with N circuit connecting ends, and at least one of the N circuit connecting ends is used for being selectively electrically coupled to at least one of the N element connecting ends according to the pin function of the microcontroller, so that the functional circuit is connected with the corresponding functional pin. Preferably, a jumper element is used to connect the at least one circuit connection end to the at least one element connection end.

It can be understood that, for the convenience of setting the jumper element, on the circuit board, the plurality of element connection ends may be set on the same side or different sides of the microcontroller, and the plurality of circuit connection ends may also be set on the same side or different sides of the microcontroller. To facilitate the provision of jumper elements, the same circuit connection end may comprise a plurality of terminals that are shorted together and the same element connection end may also comprise a plurality of terminals that are shorted together on the circuit board.
