[0002] In the process of printed circuit board (PCB) circuit design, there is often a situation where signals have to choose between two options. For this situation, two resistors are generally connected in parallel for selection and switching. However, the above solution is only applicable to low-speed signal transmission. If high-speed signal transmission is used, the above resistor selection and switching method will result in redundant stub lines. The stub lines are redundant signal line segments on the PCB circuit. The redundant stub lines can cause high-speed signal reflections, thereby seriously affecting the transmission quality of high-speed signals. In order to solve the above technical problems, switching is often performed through a high-speed signal switch chip, but the cost of this solution is relatively high. Utility Model Content

[0026] The present application embodiment provides a resistor packaging structure, specifically, Figure 1 As shown, the resistor packaging structure includes a resistor packaging component.

[0027] Among them, the resistor package assembly includes a resistor package 5 and a plurality of pins arranged on the resistor package 5, and the resistor package 5 is composed of a plurality of resistors; the pins include a main connection pin and a plurality of slave connection pins, and the main connection pin and the slave connection pin are both used to connect to the signal transmission line, and the signal transmission line connected to the main connection pin can transmit the signal to the signal transmission line connected to the slave connection pin through the resistor package 5.

[0028] In an embodiment of the present application, a main connection pin and multiple slave connection pins are set on the resistor package 5 so that the signal transmission line connected to the main connection pin can transmit the signal to the signal transmission line connected to the slave connection pin through the resistor package 5, thereby realizing multi-select signal transmission while reducing redundant signal routing of the resistor package structure, thereby reducing signal reflection, and ensuring the transmission quality of the signal without increasing the cost.

[0029] In actual applications, the main connection pin is a common pin composed of one end pins of multiple resistors, and the multiple slave connection pins are multiple connection pins composed of the other end pins of multiple resistors. Furthermore, by setting a resistor package 5 including a common pin and multiple slave connection pins, redundant signal routing can be reduced, that is, redundant stubs existing in the selection switching device composed of two resistors in parallel in the prior art can be reduced, thereby reducing signal reflection and ensuring the transmission quality of the signal.

[0030] In some embodiments, the resistor package 5 can realize stable transmission of both low-speed transmission signals and high-speed transmission signals.

[0031] In an optional embodiment, the resistor package 5 includes an input end and multiple output ends, the input end is connected to the signal transmission line through a main connection pin, the output end is arranged in a one-to-one correspondence with the slave connection pin, and the output end is connected to the signal transmission line through the slave connection pin. The signal transmitted from the signal transmission line connected to the main connection pin can be transmitted from the input end to the output end, and transmitted to the signal transmission line connected to the slave connection pin through the output end.

[0032] For details, please continue to refer to Figure 1 The input end is the end connected to the third signal transmission line 63, and the output end is the end connected to the first signal transmission line 61 and the end connected to the second signal transmission line 62. It should be noted that the output end may also include an end connected to the fourth signal transmission line and an end connected to the fifth signal transmission line. Here, Figure 1 Only two outputs are shown, but the number of outputs is not limited to Figure 1The number of output terminals shown, and further, by setting an input terminal and multiple output terminals on the resistor package 5, the resistor package 5 can be used to realize multiple signal selection while reducing the redundant signal routing of the resistor package structure, thereby reducing signal reflection and ensuring the transmission quality of the signal.

[0033] In an optional embodiment, the input end and the output end are located in different directions of the resistor package 5 .

[0034] Specifically, the input terminal and the multiple output terminals are respectively located around the resistor package 5, thereby facilitating signal transmission in multiple directions and enhancing the stability of the connection between the resistor package 5 and the signal transmission line in different directions.

[0035] In a specific embodiment, the resistor package 5 includes a plurality of resistors, pins at one end of the plurality of resistors together constitute a main connection pin, and pins at the other end of the plurality of resistors constitute a plurality of slave connection pins.

[0036] Specifically, the resistor package 5 is composed of one end pins of multiple resistors that together constitute a main connection pin, and the other end pins of the multiple resistors that constitute a plurality of slave connection pins, so that while using resistors to achieve selection switching, it can also remove residual signal lines in the signal routing process during signal transmission, thereby improving signal transmission quality.

[0037] In a specific embodiment, the resistor package 5 includes two resistors, one end pins of the two resistors together constitute a main connection pin, and the other end pins of the two resistors constitute two slave connection pins.

[0038] For details, please refer to Figure 1 The resistor package 5 includes a first resistor 51 and a second resistor 52, wherein the first resistor 51 includes pin 1 and pin 2, and the second resistor 52 includes pin 3 and pin 4. Pin 2 of the first resistor 51 and pin 4 of the second resistor 52 together constitute a main connection pin, and pin 1 and pin 3 are slave connection pins, and then the two resistors are packaged into three pins, that is, pin 2 of the first resistor 51 and pin 4 of the second resistor 52 are combined into a main connection pin, and there is no signal routing between pin 2 and pin 4. Specifically, pin 2 of the first resistor 51 and pin 4 of the second resistor 52 can be connected by welding or the like, so as to package the resistor package 5 into a package including a main connection pin and two slave connection pins to realize two-choice transmission of signals.

[0039] In some specific embodiments, pin 1 is used to connect to the first signal transmission line 61, pin 3 is used to connect to the second signal transmission line 62, and the main connection pin is used to connect to the third signal transmission line 63, wherein the third signal transmission line 63 is connected to the main connection pin, and can then be connected to the first signal transmission line 61 through the first resistor 51, or connected to the second signal transmission line 62 through the second resistor 52, so that no stub line will remain between the third signal transmission line 63 and the resistor package 5. Compared with the selection switching device composed of two resistors in parallel in the prior art, the residual stub line existing in the signal routing during the signal transmission process can be removed, thereby improving the signal transmission quality without increasing the cost.

[0040] It should be noted that the selection switching device in the prior art can refer to Figure 2 As shown, specifically, the selection switching device includes a third resistor 71 and a fourth resistor 72, wherein the third resistor 71 includes a pin 1 and a pin 2, and the fourth resistor 72 includes a pin 3 and a pin 4, wherein the pin 1 is used to connect to the first signal transmission line 61, the pin 3 is used to connect to the second signal transmission line 62, and the pin 2 and the pin 4 are used to connect to the third signal transmission line 63, and then, when the pin 1 of the third resistor 71 is welded to the first signal transmission line 61 and the pin 3 of the fourth resistor 72 is not welded to the second signal transmission line 62, the third signal transmission line 63 can be connected to the first signal transmission line 61 through the third resistor 71, and then the signal from the third signal transmission line 63 to the first signal transmission line 61 can be realized. For signal transmission, when pin 1 of the third resistor 71 is not welded to the first signal transmission line 61 and pin 3 of the fourth resistor 72 is welded to the second signal transmission line 62, the third signal transmission line 63 can be connected to the second signal transmission line 62 through the third resistor 71, thereby realizing signal transmission from the third signal transmission line 63 to the second signal transmission line 62. However, in the above two welding methods, there is a redundant signal line between the third signal transmission line 63 and the third resistor 71 or the fourth resistor 72, and this signal line becomes a stub line, which will cause signal reflection of the third signal transmission line 63 when high-speed signal transmission is performed, thereby affecting the signal transmission quality of the third signal transmission line 63.

[0041] In a specific embodiment, the resistor package 5 includes an input terminal and two output terminals, the input terminal is connected to the signal transmission line through the main connection pin, the output terminal is set in a one-to-one correspondence with the slave connection pin, and the output terminal is connected to the signal transmission line through the slave connection pin.

[0042] For details, please continue to refer to Figure 1, one input end is the end connected to the third signal transmission line 63, and the output end is the end connected to the first signal transmission line 61 and the end connected to the second signal transmission line 62. Furthermore, by setting an input end and two output ends on the resistor package 5, the resistor package 5 can be used to realize the signal selection of two signals while reducing the redundant signal routing of the resistor package structure, thereby reducing signal reflection and ensuring the transmission quality of the signal.

[0043] In a specific embodiment, one input terminal and two output terminals are respectively located in different directions of the resistor package 5, and the two output terminals are arranged opposite to each other.

[0044] For details, please refer to the specific location of one input terminal and two output terminals. Figure 1 As shown, this further helps signal transmission in two directions and enhances the stability of the connection between the resistor package 5 and the signal transmission line in two directions.

[0045] In another specific embodiment, the resistor package 5 includes three resistors, one end pins of the three resistors together constitute a main connection pin, and the other end pins of the three resistors constitute three slave connection pins.

[0046] In the embodiment of the present application, the resistor package 5 may further include three resistors. Specifically, the resistor package 5 includes a first resistor 51, a second resistor 52 and a fifth resistor. It should be noted that: Figure 1 The fifth resistor is not exhibited in the figure, wherein the first resistor 51 includes pin 1 and pin 2, the second resistor 52 includes pin 3 and pin 4, and the fifth resistor includes pin 5 and pin 6. Pin 2 of the first resistor 51, pin 4 of the second resistor 52 and pin 6 of the fifth resistor together constitute a main connection pin, and pin 1, pin 3 and pin 5 are slave connection pins. Then, the three resistors are packaged into four pins, that is, pin 2 of the first resistor 51, pin 4 of the second resistor 52 and pin 6 of the fifth resistor are combined into a main connection pin, and there is no signal routing between pin 2, pin 4 and pin 6. Specifically, pin 2 of the first resistor 51, pin 4 of the second resistor 52 and pin 6 of the fifth resistor can be connected by welding or the like, so as to package the resistor package 5 into a package including a main connection pin and three slave connection pins to realize three-to-one transmission of signals.

[0047] In some specific embodiments, pin 1 is used to connect to the first signal transmission line 61, pin 3 is used to connect to the second signal transmission line 62, pin 5 is used to connect to the fourth signal transmission line, and the main connection pin is used to connect to the third signal transmission line 63, so that no stub line will remain between the third signal transmission line 63 and the resistor package 5, thereby improving the transmission quality of the signal.

[0048] In a specific embodiment, the resistor package 5 includes an input terminal and three output terminals, the input terminal is connected to the signal transmission line through the main connection pin, the output terminal is set in a one-to-one correspondence with the slave connection pin, and the output terminal is connected to the signal transmission line through the slave connection pin.

[0049] Specifically, an input end is an end connected to the third signal transmission line 63, and the output end is an end connected to the first signal transmission line 61, an end connected to the second signal transmission line 62, and an end connected to the fourth signal transmission line. Furthermore, by setting an input end and three output ends on the resistor package 5, the resistor package 5 can be used to realize three-in-one signal selection while reducing redundant signal routing of the resistor package structure, thereby reducing signal reflection and ensuring the transmission quality of the signal.

[0050] In a specific embodiment, one input terminal and three output terminals are respectively located in different directions of the resistor package 5 , one output terminal is arranged opposite to the input terminal, and the remaining two output terminals are arranged opposite to each other.
