Fan connector featuring two terminals in single slot to replace printed circuit board

Two sets of terminals in a single slot to replace the fan connector of the printed circuit

The present invention is a fan connector in which two sets of terminals are arranged in a single slot to replace a printed circuit, in particular, an upper and lower rows of terminals are embedded in a slot of an insulating base, and the upper row of terminals can be connected to the control chip. The lower row of terminals can be electrically connected to the fan to be clamped by the terminals when an external plug is inserted into the slot, thereby enabling the signal to be transmitted to the brand new structure on the fan.

According to the rapid development of electronic technology, the processing efficiency and speed of electronic devices (such as personal computers, servers, etc.) are also increasing. The greater the amount of information contained in electronic signals and the faster the processing speed, When the electronic equipment is in operation, the temperature of its internal components will rise rapidly. Therefore, how to effectively cool the inside of the electronic equipment can be said to be one of the key factors affecting its 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 adjusts the power signal of the driving fan to control the speed of the fan (ie, when the temperature is low, the fan speed is lowered). In this method of changing the rotational speed, a pulse-type power signal (hereinafter referred to as a PWM signal) is generated by a Pulse Width Modulation (PWM) technique to change the transmission. The pulse width, on-time or duty cycle allows the fan's speed to change.

The above method of controlling the fan speed through the PWM technology allows the fan to dissipate heat more efficiently, but there are still many imperfections in practice. First, since the fan cannot be directly driven by the PWM signal, it must pass through a The PWM module first converts the received PWM signal 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 (that is, the circuit board and the transmission line on it) take up too much space, affecting the overall configuration, and is also cumbersome to install, which will cause many restrictions for the industry.

In order to solve this problem, the creator has designed a fan connector and has applied for patent protection. As shown in FIG. 1 , the fan connector 1 is locked to a fan 10 and includes an insulating seat. 11. A control chip 12, a set of signal terminals 13 and a set of power terminals 14, wherein the front end of the insulating base 11 is provided with a first slot 111 and a second slot 112, and the signal terminal 13 One end extends into the top side of the first slot 111, and the other end is electrically connected to the control wafer 12; the power terminal 14 is U-shaped and has one end extending into the first slot 111. The bottom side of the bottom side extends into the second slot 112 to be connected to the transmission line 102 on the fan 10 through a fan plug 101. Accordingly, the terminals 13 and 14 can replace the conventional The transmission signal function of the printed circuit is such that the design of the fan connector 1 can greatly reduce the configuration space required for the fan 10 to be around.

However, the creator discovered the aforementioned fan connector 1 during the subsequent research. There is still room for improvement, which should be able to further reduce its size and improve the assembly method. Therefore, how to further improve the structure of the fan connector and the arrangement of the terminals under the above-mentioned creation, so that the fan connector can better conform to the current The design trend of "light, thin and short" in the industry has become an important issue that this creation is intended to solve.

In view of the fact that in the past, when an electronic device wants to transmit a PWM signal to control the speed of the fan, a circuit board must be installed adjacent to the fan to configure the PWM module and the two sets of sockets, resulting in an excessive space occupation, and the creator relies on Based on years of practical experience and based on the previously designed fan connector, after re-improvement, I finally designed a fan connector that is equipped with two sets of terminals in a single slot to replace the printed circuit. A connector that is lighter in weight, easier to assemble, and less expensive.

One of the purposes of the present invention is to provide a fan connector in which a plurality of sets of terminals are arranged in a single slot instead of a printed circuit, and is mounted in an electronic device. The fan connector includes an insulating base, a control chip, a plurality of first connecting terminals and a plurality of second connecting terminals, wherein the insulating seat system is disposed in the electronic device adjacent to a fan, the insulating seat is provided with a slot on the front side, and the rear side is provided with a plurality of Each of the terminal slots is connectable to the slot; the control chip is mounted on the insulating base; the first connecting terminals are embedded in the insulating base, and the first connecting terminals are One end is exposed to a position adjacent to the top in the slot, and the other end is electrically connected to the control chip; one end of the plurality of second connection terminals can respectively pass through each of the terminal slots to extend into The slot is adjacent to the bottom end, and the other end of the slot is electrically connected to the fan. When an external plug is inserted into the slot, the first connection terminal and the second connection terminal can respectively be respectively received. Rely on The outer plug top and bottom surfaces, And electrically connected to the electrode contacts on the external plug, so that the signal transmitted by the external plug can be transmitted to the fan through the first connection terminal, the control chip and the second connection terminal, and the fan is driven to operate. Accordingly, since the fan connector has only a single socket for plugging, and the second connecting terminals can be directly connected to the transmission line on the fan, the volume can be further reduced, and the assembly complexity can be simplified.

In this way, since the fan connector 2 can integrate the electronic components such as the control chip 22 and the two sets of connection terminals P1 and P2 into the insulating base 21, the manufacturer does not need to separately solder a circuit board adjacent to the fan. The control chip 22 and the socket for the conventional signal plug and the fan plug are connected, and the same signal transmission function as the prior art can be completed through the fan connector 2. In addition, compared with the fan connector previously applied by the applicant, this creation not only reduces the number of slots, but also not only the volume can be more streamlined, but also greatly improves the assembly method and raw material cost.

Referring to Figures 2 and 3, in the present embodiment, the other end of the second connection terminal P2 is provided with a clamping portion P21 having a U-shaped cross-sectional configuration. Capable The transmission line P3 on the fan is held, that is, the second connection terminals P2 can be integrated with the transmission line P3 on the fan without being connected through a fan plug as in the prior art.

Moreover, as shown in FIG. 2 to FIG. 5, a mounting groove 212 is further disposed at a position adjacent to the top end of the insulating seat 21, and the mounting groove 212 can communicate with the slot 210, and the bottom side of the inner wall is provided. There are a plurality of guiding grooves 212a, and the width of the guiding grooves 212a is matched with the first connecting terminals P1; the fan connector 2 further includes an insulating plate body 23, and the first connecting terminals P1 are adjacent to each other. One end portion is fixed in the insulating plate body 23, and one end of the first connecting terminal P1 is along the guiding groove 212a during the process of inserting the insulating plate body 23 into the mounting groove 212. And passing through the mounting groove 212, and then extending into the slot 210, and the side edge of the insulating plate body 23 can be engaged with the inner wall surface of the mounting groove 212.

The control wafer 22 can be mounted in the insulating body 21 in various manners (eg, embedded in one of the mounting holes of the insulating body 21). In this embodiment, the control chip 22 is mounted on the insulating plate. a positioning hole 230 is disposed on the insulating plate body 23, and the other end of the first connecting terminal P1 can extend into the positioning hole 230, and the control wafer 22 can be positioned into the positioning hole 230, so that the control chip 22 can be positioned into the positioning hole 230. The pins are electrically connected to the other ends of the first connection terminals P1, respectively.

Referring to FIG. 4, in order to increase the positioning strength between the connecting terminals P1 and P2 and the external plug, one end of the second connecting terminal P2 extends in a direction of the first connecting terminal P1 and is provided with a spring piece. P22, the elastic piece P22 has a V-shape and extends from one end of the second connection terminal P2 toward the upper side and the rear side, so that one side of the elastic piece P22 can form an abutting arm for pushing into the insertion. The plug 210 is externally connected to the plug. In addition, the fan connector 2 can be directly locked to the front end of the fan.

On the other hand, when the signal transmitted by the external plug is a PWM signal, the fan connector 2 transmits the signal to the control chip 22 through the first connection terminal P1, and then converts the adjusted power supply signal. The other part of the first connection terminal P1 is passed back to the external plug, and then through the circuit on the external plug, the signal is transmitted to the second connection terminals P2 on the bottom surface of the external plug, thereby driving the fan.
