Description

A fan connector that uses a signal and power terminal instead of a printed circuit to reduce the size

The present invention relates to a fan connector that uses a signal and a power terminal instead of a printed circuit to reduce the volume, in particular, a two-slot and a control chip are disposed on an insulating base, and the slots are respectively provided with a plurality of signal terminals. And the power terminal, when the external signal plug and the fan plug are respectively plugged into the slots, the control signal transmitted from the signal plug can be converted into a power supply signal by the control chip, and the power terminal and the fan plug are A power signal is transmitted to the fan to drive the fan to rotate.

According to the rapid development of electronic technology, the processing efficiency and speed of electronic devices (such as personal computers, servers, etc.) are also rising. However, due to the accompanying current of electronic signals, the greater the amount of information contained in electronic signals. The faster the processing speed is, the higher the temperature of each component inside the electronic device will rise rapidly. Therefore, how to effectively cool the inside of the electronic device can be said to be one of the key factors affecting the operational efficiency.

At present, electronic devices generate airflow for cooling by means of an internally configured "fan", and in order to control power consumption more accurately, operators have designed a fan that can change the rotational speed, that is, the processing unit in the electronic device can be based on The current ambient temperature (ie, when the temperature is low, that is, the fan speed is lowered), the power signal of the driving fan is adjusted to control the fan speed. This method of changing the rotational speed is mostly pulse width modulation (Pulse Width Modulation, hereinafter referred to as The PWM technology generates a pulsed power signal (hereinafter referred to as a PWM signal) to change the pulse width, on-time or duty cycle to change the fan speed.

The above method of controlling the fan speed through the PWM technology allows the fan to dissipate heat more efficiently. However, there are still many imperfections in practice. First, the fan cannot be directly driven by the PWM signal, but must pass through A PWM module converts the received PWM signal first and starts to operate correctly. The current practice in the industry is to install a circuit board in the vicinity of the fan in the electronic device. The circuit board is provided with the PWM module and two sockets, and the sockets are respectively connected with a host plug and a fan plug. The PWM signal transmitted from the host plug can be guided to the PWM module through the printed circuit on the circuit board, converted into a corresponding power signal, and then driven by the fan plug to drive the fan to rotate. However, this practice will occupy too much space in the electronic device, affecting the overall configuration, and is also cumbersome to install, which will cause many restrictions for the industry.

In addition, not all types of electronic devices can control the fan speed through PWM technology. Depending on the application background or production cost, some electronic devices may not be equipped with PWM modules. Therefore, if the manufacturer is producing a fan, The PWM module and the circuit board are locked together on the fan casing. As a single product, the manufacturer must design another fan with no PWM module to meet the needs of all customers. It will cause great inconvenience to the production process and warehouse management.

Based on the above issues, the creator thinks, can you design a special fan connector instead of the previous configuration of the PWM module on the circuit board? And the fan connector must be able to effectively reduce the required space, and can be easily assembled by the operator, and has flexibility in setting to respond to various types of electronic devices (ie, having a PW module or not having a PWM module). , How to design a perfect connector structure and achieve the above-mentioned goals of the creator is an important issue that this creation is intended to solve.

In view of the fact that in the past, when the operator wanted to add a control speed function to the fan, an additional circuit board must be installed to configure the PWM module, but this caused the problem of excessive occupation of the internal space of the electronic device. The creator relied on years of practical experience. After many experiments and researches, I finally designed a fan connector that uses signal and power terminals instead of printed circuits to reduce the volume, which can effectively solve the lack of conventional technology.

One of the purposes of the present invention is to provide a fan connector that uses a signal and a power terminal instead of a printed circuit to reduce the volume. The fan connector is mounted in an electronic device, including an insulating base, a control chip, and a plurality of branches. The signal terminal and the plurality of power terminals are disposed in the electronic device adjacent to a fan. The insulating seat is respectively provided with a first slot and a second slot, and the first slot is The configuration is matched with the configuration of a signal plug, and the configuration of the second slot is matched with the configuration of a fan plug on the fan; the control chip is mounted on the insulating base; the signals are The terminal is embedded in the insulating base, one end of the signal terminals is exposed to the first slot, and the other end is electrically connected to the control chip; the power terminals are embedded in the insulation One end of the body can be exposed to the first slot, and the other end can be exposed to the second slot; the signal plug and the fan plug are respectively inserted into the first slot and the second slot In the case of the inside One of the terminals can clamp the signal plug and is electrically connected to the electrode contact on the signal plug, and the other end of the power terminal can be electrically connected to the fan plug to make the control signal on the signal plug Passing through the signal terminals, the control chip is converted into a power supply signal, and then through the power terminals and the fan A plug is passed to the fan to drive the fan to rotate. In this way, by providing a signal terminal and a power terminal in the insulating body, the problem that the printed circuit board occupies too much space and is difficult to assemble in the prior art can be solved, and the fan connector is light in size, so that the operator can more conveniently use the fan. Install the function of controlling the speed.

The present invention is a fan connector that uses a signal and a power terminal instead of a printed circuit to reduce the volume. Referring to FIG. 1 , in the first preferred embodiment of the present invention, the fan connector 1 is mounted on an electronic device.

Limited.

As shown in FIG. 1 to FIG. 2, the first socket 111 and the second slot 112 are respectively disposed on the insulating base 11. The first slot 111 is configured with a signal plug (eg, a connection The configuration of the second slot 112 is matched with the configuration of the fan plug 101 on the fan 10; the control chip 120 is mounted on the insulating base 11 The PWM signal can be converted into a power signal that the fan 10 can receive.

Referring to FIGS. 1~3, the signal terminals P1 are embedded in the insulating base 11, and one end thereof is exposed to the first slot 111 and adjacent to the top end, and the other end can be The control chip 120 is electrically connected; the power terminal P2 is also embedded in the insulating base 11 and one end thereof can be exposed to a position adjacent to the bottom end of the first slot 111, and the other end can be exposed at the same end. The second slot 112; in the case that the signal plug and the fan plug 101 are respectively inserted into the first slot 111 and the second slot 112, one end of the terminals P1 and P2 can respectively clamp the signal The top surface and the bottom surface of the plug are electrically connected to the electrode contacts on the signal plug, and the other end of the power terminal P2 can be electrically connected to the fan plug 101 to make a control signal on the signal plug (ie, The PWM signal can be converted into a power supply signal by the control chip 120 through the signal terminal P1, and then transmitted to the fan 10 through the power terminal P2 and the fan plug 101 to drive the fan 10 to rotate.

In this way, since the fan connector 1 can integrate the electronic components such as the control chip 120, the signal terminal P1, and the power terminal P2 into the insulating base 11, the manufacturer does not need to separately solder a circuit board adjacent to the fan 10. The control chip 120 and the socket for the signal plug and the fan plug 101 are connected, that is, the signal terminal P1 and the power terminal P2 can replace the function of the printed circuit on the printed circuit board, and at the same time, pass through the insulating body. The structure of the slots 111 and 112 on the 11th can effectively utilize the space around the fan 10 to improve the design flexibility of the electronic device.

As shown in FIG. 1 to FIG. 4 , a third slot 113 is further disposed on the rear side of the insulating base 11 , and the third slot 113 is in communication with the first slot 111 , and the fan connector 1 is An insulating plate body 12 is further disposed. The portion of the signal terminal P1 adjacent to the other end is fixed in the insulating plate body 12 (for example, through an injection molding process), so that the insulating plate body 12 is inserted into the first In the case of the three slots 113, one end of the signal terminals P1 can protrude into the first slot 111.

A positioning hole 121 is defined in the insulating plate body 12. The other end of the signal terminal P1 can extend into the positioning hole 121, and the control chip 120 can be positioned in the positioning hole 121 to be pinned. The other end of the signal terminal P1 is electrically connected to the other end, and a cover 122 can be pivotally connected to the insulating plate 12 to shield the control wafer 120. In this embodiment, the control signal on the signal plug is transmitted to the control chip 120 through the partial signal terminal P1, and is converted into a power supply signal, and then transmitted back to the other part of the signal terminal P1. The signal plug is transmitted to the power terminal P2 on the bottom surface of the signal plug through the circuit on the signal plug, and then transmitted to the fan plug. However, the signal transmission path can be adjusted according to the needs of the operator, not limited to the foregoing manner. The main purpose of the present invention is to package two sets of terminals P1 and P2 and a control wafer 120 in the insulating base 11 to reduce the problem that the printed circuit board is too bulky and difficult to assemble in the prior art.

In addition, in the embodiment, the insulating base 11 is locked on the front side of the fan 10. Therefore, the first slot 111 and the second slot 112 can be disposed on the fan connector 1 away from the fan. One side of the 10 (ie, the front side of the fan connector 1) is provided for assembly by the assembler. In addition, the power terminals P2 are U-shaped, and the first slot 111 and the second slot 112 can communicate with the rear side of the insulating base 11 so that the power terminals P2 can be insulated from the insulating base. The rear side of the 11 is inserted into the first slot 111 and the second slot 112, respectively.

Moreover, since the power terminals P2 are U-shaped, the two ends can be located in the first slot 111 and the second slot 112. Therefore, in order to prevent the power terminals P2 from being plugged into the fan plug, Improper application of the assembly personnel causes the power terminal P2 to be loose and displaced rearward. The insulation seat A fourth slot 114 is disposed on the body 11 , and the fourth slot 114 is disposed on a side of the rear side of the insulating base 11 corresponding to the second slot 112 and can be coupled to the first slot 111 and The second slot 112 is in communication, and the fan connector 1 further includes a stop block 13 , the stop block 13 can be embedded in the fourth slot 114 , and its position corresponds to the middle of the power terminal P2 unit. Accordingly, when the power terminal P2 is loose, the middle portion thereof will abut against the stop block 13 without affecting the stability of its signal transmission.
