Description

Electrical connector used for computer fan serial connection

The present invention provides an electrical connector for serial connection of computer fans, especially a plurality of computer fans and a lighting fan hub distributor can be connected to each other through a double-plug connection cable without worrying about the directionality problem. At the same time, there are 8-PIN applicable signal terminals for controlling fan speed, lighting mode and power signal, which is more than the known electrical connectors using 4-6PIN signal terminals, so the fan speed and the lighting mode of the RGB light-emitting diode can be accurately controlled. Moreover, since there are 4-PIN power terminals and ground terminals, it is helpful to provide a large current supply to the fan motor to reduce the difference between the preset speed and the actual speed, so that the fan speed can be adjusted to the preset speed more quickly. The USB-C connector has the advantage of being small in size, which helps to design a 90-degree turn structure between the electrical connector and the cable, making the wiring space inside the computer more flexible.

With the rise of the e-sports industry, the performance of computers used in e-sports must also meet the requirements of online games where every second counts. The improvement of computer performance is also accompanied by an increase in the heat generated by the computer's internal components, which has a serious impact on the computer's performance and lifespan. Therefore, a good heat dissipation device must be provided to cool the computer components to ensure smooth computer operation. Computer fans are widely used in desktop computers as air-cooling devices for high-temperature electronic components, or in water-cooling systems to dissipate heat from water-cooling radiators with high-temperature liquid pipes. In addition to the heat dissipation function, computer fans are also used in e-sports computer hosts. In addition, they need to be equipped with a light ring with multiple RGB LEDs in the computer fan to achieve multi-color lighting and flashing, thereby producing a colorful and dazzling effect.

Since there are many computer fans installed in gaming consoles, some are single fans and some are multiple fans connected in series. Whether it is a single fan or multiple fans connected in series, it is usually necessary to connect to a lighting fan hub (RGB HUB) via a cable to control the lighting mode and fan speed of each computer fan. However, the cable used for computer fans is composed of four signal lines, and the four signal lines with the 4-PIN signal terminal electrical connector include power signal, ground signal, fan speed control and multiple RGB LED control. Since the number of signal lines in the cable is too small to perform precise control, the fan speed control is not precise enough and the lighting mode of the RGB LED is too monotonous. This is undoubtedly a fatal flaw for gaming consoles that pursue extreme lighting effects. The aforementioned inaccuracy in controlling each computer fan through a lighting and fan hub distributor needs to be improved and resolved by those in the industry.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information, evaluated and considered various aspects, and used his many years of experience in this industry to continuously create and modify, and finally designed the invention patent of this electrical connector used in computer fan serial connection.

The present invention is mainly used for an electrical connector for serial connection of computer fans, wherein: A1, A12, B1, B12 of the input USB-C socket connector and the output USB-C socket connector are ground terminals; A4, A9, B4, B9 are power terminals; A5, B5 are the first custom terminals for addressable multi-color lights; A6, B6 are the second custom terminals for fan data output; A7, B7 are the third custom terminals for fan data input; A8, B9 are the fourth custom terminals for detecting fan speed or for backup, and A2, A3, A10, A11, B2, B3, B10, B11 are undefined terminals; the dual-plug USB-C connector A1 and A12 are ground terminals; A4 and A9 are power terminals; A5 is the first custom terminal for addressable multi-color lighting; A6 is the second custom terminal for fan data output; A7 is the third custom terminal for fan data input; A8 is the fourth custom terminal for detecting fan speed or for backup, and A2, A3, A10, and A11 are undefined terminals. When one end of the dual-plug USB-C connector is plugged into the output USB-C socket connector of the computer fan, and the other end of the dual-plug USB-C connector is plugged into the input USB-C socket connector of the adjacent computer fan in the forward or reverse direction, the correct electrical connection signal can be obtained. The aforementioned multiple computer fans and lighting fan hubs can be connected to each other through double-plug cables without worrying about directionality. At the same time, there are 8-PIN applicable signal terminals for controlling fan speed, lighting mode and power signal, which is more than the conventional electrical connectors with 4-6PIN signal terminals. Therefore, the fan speed and the lighting mode of the RGB light-emitting diode can be accurately controlled. Moreover, since there are 4-PIN power terminals and ground terminals, it is helpful to provide a large current supply to the fan motor to reduce the difference between the preset speed and the actual speed, so that the fan speed can be adjusted to the preset speed more quickly. The USB-C connector has the advantage of being small in size, which helps to design a 90-degree turn structure between the electrical connector and the cable, making the wiring space inside the computer more flexible.

The secondary purpose of the present invention is that the first custom terminal controls the control signal of the plurality of multi-color LEDs in the computer fan, and forms a predetermined color display and light flashing for the multi-color LEDs according to the addressing control means.

Another purpose of the present invention is that the second custom terminal and the third custom terminal form a set of control signals for the device code, device firmware version, number of LEDs, temperature of the heat sink, fan speed, fan installation direction and reserved value in the computer fan, and the temperature of the heat sink and the actual fan speed are detected through the fourth custom terminal to automatically compensate and adjust the fan speed, and the fan motor is adjusted to a predetermined speed through pulse width modulation.

Another purpose of the present invention is to connect the computer fans connected in series to a lighting fan hub distributor via a double-plug connection cable to distribute and control the lighting mode and fan speed of each computer fan.

Another purpose of the present invention is that the computer fans connected in series are further connected to a power supply unit through a power connection line, and the power supply unit refers to a power supply or a motherboard, and the power connection line has a built-in transformer that reduces the 12V DC voltage to 5V DC voltage.

In order to achieve the above-mentioned purpose and effect, the technical means and structure, implementation method, etc. adopted by the present invention are described in detail in the following figure for the preferred embodiment of the present invention, so as to facilitate a complete understanding.

Please refer to Figures 1-2, 5-7, which are schematic diagrams of multiple computer fans connected in series, another schematic diagram of multiple computer fans connected in series, a diagram of the upper and lower rows of terminals on the input USB-C socket connector, a diagram of the upper and lower rows of terminals on the output USB-C socket connector, and a diagram of the upper and lower rows of terminals on the double-plug USB-C connector. It can be clearly seen from the figures that the computer fan 1 of the present invention includes an input USB-C socket connector 11, an output USB-C socket connector 12, and a double-plug USB-C connector 13 composed of a USB-C hardware interface, wherein:

The input USB-C socket connector 11 (as shown in FIG. 5) and the output USB-C socket connector 12 (as shown in FIG. 6) include twelve terminals A1 to A12 in the upper row from left to right, wherein A1 and A12 are ground terminals (GND); A4 and A9 are power terminals (VBUS); A5 is the first custom terminal for addressable multi-color lighting (ARGB); A6 is the second custom terminal for fan data output (DATA OUT); A7 is the third custom terminal for fan data input (DATA IN); A8 is the fourth custom terminal for detecting fan speed (FAN DETECT) or for standby (RESERVED PIN), and A2, A3, A10, and A11 are undefined terminals.

The input USB-C socket connector 11 (as shown in FIG. 5) and the output USB-C socket connector 12 (as shown in FIG. 6) include twelve terminals B1 to B12 in the lower row from right to left, of which B1 and B12 are ground terminals; B4 and B9 are power terminals; B5 is the first custom terminal for addressable multi-color lights; B6 is the second custom terminal for fan data output; B7 is the third custom terminal for fan data input; B8 is the fourth custom terminal for detecting fan speed or for standby, and B2, B3, B10, and B11 are undefined terminals.

The dual-plug USB-C connector 13 includes twelve terminals in the upper row from right to left, namely A1 to A12, and twelve terminals in the lower row are undefined terminals, wherein A1 and A12 are ground terminals; A4 and A9 are power terminals; A5 is the first custom terminal for addressable multi-color lights; A6 is the second custom terminal for fan data output; A7 is the third custom terminal for fan data input; A8 is the fan rotation detection terminal. The fourth custom terminal is used for speed or standby, while A2, A3, A10, and A11 are undefined terminals. When one end of the dual-plug USB-C connector 13 is plugged into the output USB-C socket connector 12 of the computer fan 1, and the other end of the dual-plug USB-C connector 13 is plugged into the input USB-C socket connector 11 of the adjacent computer fan 1 in the forward or reverse direction, the correct electrical connection signal can be obtained.

The above-mentioned computer fans 1 connected in series are further connected to a power supply unit 3 through a power connection line 16. The power supply unit 3 refers to a power supply (Power Supply) or a motherboard (Mother Board), and the power connection line 16 has a built-in transformer (not shown in the figure) that reduces the 12V DC voltage to a 5V DC voltage.

The control signal of the first custom terminal (A5, B5) to the multiple multi-color LEDs (ARGB LED) in the computer fan 1 is used to form a predetermined color display and light flashing for the multi-color LEDs according to the addressing control means.

The second custom terminal (A6, B6) and the third custom terminal (A7, B7) form a set of control signals for the device code, device firmware version, number of LEDs, temperature of the heat sink, fan speed, fan installation direction and reserved value in the computer fan 1, and the temperature of the heat sink and the actual fan speed are detected through the fourth custom terminal (A8, B8) to automatically compensate and adjust the fan speed, and the fan motor is adjusted to a predetermined speed through a pulse width modulation (PWM) method. The driving voltage of the computer fan 1 is preset to 5V, and there is also a 5V voltage difference between the power terminal (VBUS) and the ground terminal (GND) of the input USB-C socket connector 11 and the output USB-C socket connector 12, instead of using the traditional 12V driving voltage to drive the computer fan 1. If the power supply unit 3 provides a 12V DC voltage to the computer fan 1, the built-in transformer of the power connection line 16 can be used to reduce the 12V DC voltage to a 5V DC voltage, so as to prevent the USB-C electronic device that can only accept 5V from being damaged or burned when it is inserted incorrectly.

The computer fans 1 connected in series are further connected to a lighting fan hub 2 (RGB HUB) via a double-plug connection cable 15 to control the distribution of the lighting mode and fan speed of each computer fan 1. The definition of the terminals inside the double-plug connection cable 15 is the same as that of the double-plug USB-C connector (13, 14), so the terminals inside the double-plug connection cable 15 are not repeated. The lighting fan hub distributor 2 is internally provided with a microcontroller unit (MCU) and a plurality of input/output ports (I/O Ports), and the plurality of input/output ports are also constituted by USB-C socket connectors, and the plurality of serially connected computer fans 1 are electrically connected by plugging the double-plug connection cables 15 into the corresponding input/output ports, so that the lighting mode and fan speed of each computer fan 1 can be individually controlled through the lighting fan hub distributor 2.

Please refer to Figures 3 and 4, which are another embodiment of the computer fan of the present invention and its serial connection diagram, wherein the computer fan 1 is provided with a first elliptical first receiving groove 101 in the first corner recess, and an input end USB-C socket connector 11 is provided at each of the two ends of the first receiving groove 101; and a second elliptical second receiving groove 102 is provided in the adjacent second corner recess, and an output end USB-C socket connector 12 is provided at each of the two ends of the second receiving groove 102. A dual-plug USB-C connector 13 capable of flexible bending and rotation is provided in each of the first receiving slot 101 and the second receiving slot 102. The pin definition inside the dual-plug USB-C connector 13 capable of flexible bending and rotation is the same as that disclosed in the above paragraph [0015]. By pre-fixing the dual-plug USB-C connector 13 capable of flexible bending and rotation in the first receiving slot 101 and the second receiving slot 102, consumers do not need to purchase a rigid dual-plug USB-C connector 13 as disclosed in FIG. 1, thereby increasing market sales competitiveness. On the other hand, when connecting multiple computer fans 1 in series, one only needs to insert one end of the flexible bending and turning double-plug USB-C connector 13 located in the first receiving slot 101 into the semicircular groove and pull it out with a finger, and then connect the exposed plug connector to the output end USB-C socket connector 12 of the second receiving slot 102 of another computer fan 1 (the flexible bending and turning double-plug USB-C connector 13 located in the second receiving slot 102 has been removed in advance), and the serial connection of the two computer fans 1 can be completed, which is convenient to use, and the computer fans 1 can be completely fitted together to reduce the volume after assembly. If you want to electrically connect the computer fan 1 to the light fan hub 2, you only need to replace the double-plug USB-C connector 13 that can be flexibly bent and turned with a double-plug connection cable 15.

The computer fan control method of the present invention is as follows: a computer user interface software (PC UI Software) (not shown) is used to control the fan speed and lighting mode of the RGB light-emitting diode of the plurality of computer fans 1 electrically connected to the light fan hub distributor 2, and the serial computer fans 1 are edited from small to large according to the distance from the light fan hub distributor 2 from near to far, and each computer fan 1 is provided with an ID chip (ID) for maintaining the fan at a predetermined speed. Chip), and computer fan 1 will automatically return the data stored in the identity chip to a predetermined register set inside the identity chip of the previous device (for example: the serial number of the previous computer fan 1 or light fan hub 2) at a predetermined interval (for example: 30 milliseconds), for example, the following table:

By using the first table above, the lighting fan hub 2 can calculate that it is electrically connected to three computer fans 1, so that the lighting fan hub 2 can adjust the fan speed and the lighting mode of the RGB LED for multiple computer fans 1 more accurately.

The data stored in the identification chip of each computer fan is as shown in the following table:

According to the above second table, the data stored in the ID chip inside the computer fan 1 include: device code, device firmware version, number of LEDs, temperature of heat sink, fan speed, fan installation direction and reserved value. The aforementioned data are the targets transmitted (TX)/received (RX) by the second custom terminal (A6, B6) and the third custom terminal (A7, B7), and are not limited to the conventional technology that can only detect fan speed and heat sink temperature. The data that can be transmitted and received are more diverse, and the control of the computer fan 1 and the lighting fan hub 2 is more accurate.

Please refer to FIG. 8 , which is a diagram of the upper and lower rows of terminal function definitions of another dual-plug USB-C connector. Compared with the embodiment disclosed in FIG. 7 , the difference is that the dual-plug USB-C connector 13 disclosed in FIG. 7 sets the defined terminals in the upper row of twelve terminals A1 to A12; on the other hand, the dual-plug USB-C connector 14 disclosed in FIG. 6 sets the defined terminals in the lower row of twelve terminals.

When one end of the dual-plug USB-C connector 13 is plugged into the output USB-C socket connector 12 of the computer fan 1, and the other end of the dual-plug USB-C connector 13 is inserted into the input USB-C socket connector 11 of the adjacent computer fan 1 in the forward or reverse direction, the correct electrical connection signal is obtained. Therefore, they are proposed together for protection. The following technical contents are disclosed in FIG. 5, 6, and 7:

The input USB-C socket connector 11 (as shown in FIG. 5) and the output USB-C socket connector 12 (as shown in FIG. 6) include twelve terminals A1 to A12 in the upper row from left to right, wherein A1 and A12 are ground terminals (GND); A4 and A9 are power terminals (VBUS); A5 is the first custom terminal for addressable multi-color lighting (ARGB); A6 is the second custom terminal for fan data output (DATA OUT); A7 is the third custom terminal for fan data input (DATA IN); A8 is the fourth custom terminal for detecting fan speed (FAN DETECT) or for standby (RESERVED PIN), and A2, A3, A10, and A11 are undefined terminals.

The main technical features of the present invention are: when multiple computer fans 1 and the lighting fan hub 2 are connected to each other through a double-plug connection cable 15, there is no need to worry about the direction problem. At the same time, there are 8-PIN applicable signal terminals for controlling fan speed, lighting mode and power signal, which is more than the 4-6PIN signal terminal electrical connector used in the prior art, so the fan speed and the lighting mode of the RGB light-emitting diode can be accurately controlled. Moreover, since there are 4-PIN power terminals and ground terminals, it is helpful to provide a large current supply to the fan motor to reduce the difference between the preset speed and the actual speed, so that the fan speed can be adjusted to the preset speed more quickly. The USB-C connector has the advantage of being small in size, which helps to design a 90-degree turn structure between the electrical connector and the cable, making the wiring space inside the computer more flexible.
