Description

Multiple computer light fans can be connected in parallel

The present invention relates to a structure of a computer lighting fan, in particular to a computer lighting fan that can be connected in multiple units.

In the approved Republic of China new model certificate No. M580203, a "computer light-emitting fan with multiple connections" is proposed, which includes a body, a fan blade is provided at the center of the body, and a light-emitting area is provided at the top of the body at least on two sides of the fan blade. A power socket and a first connector are provided on one side of the body, and a second connector is provided on the other side of the body. The power socket is electrically connected to the first connector, the second connector, the fan blade and the light-emitting area respectively, so that after the power socket on one side of the body is plugged in, the fan blade of the body can be driven to rotate and the light-emitting area can be illuminated, and after the first connector of the body is connected to the second connector of another body, the fan blade of the other body can be driven to rotate and the light-emitting area can be illuminated.

The first connector and the second connector of the above-mentioned prior art are fixedly arranged on the body of the fan. After a period of use, the electrodes are prone to oxidation or wear, which leads to poor contact or failure. At this time, the entire computer light-emitting fan must be replaced or discarded, which affects the service life of the light-emitting fan and causes waste.

First, please refer to Figures 1 and 2, which are the structural exploded view and partial structural exploded view of an embodiment of the present invention of a computer light-emitting fan that can be connected in multiples. An embodiment of the present invention of a computer light-emitting fan that can be connected in multiples includes: an outer frame 10, a motor and a fan blade 20 configured on the motor (the motor is located below the fan blade 20 and is not shown due to the viewing angle), a sliding electrical connector 30, and a power connector 40.

A first electrical connection portion 11 and a second electrical connection portion 12 are provided on the same side of the outer frame 10. The first electrical connection portion is provided with a plurality of first electrodes 111 (electrodes), and the second electrical connection portion 12 is provided with a plurality of second electrodes 121. The first electrodes 111 of the first electrical connection portion 11 and the second electrodes 121 of the second electrical connection portion 12 are electrically connected in parallel and can be electrically connected through wires arranged in the outer frame 10. The outer frame 10 is used to connect to the outer frame 10 of another light-emitting fan. A snap-fitting part 13 is disposed on one side of the outer frame 10 (see FIG. 2 for another view angle), and a snap-fitting part 14 that can match the snap-fitting part 13 is disposed on the other side of the outer frame 10. The outer frames 10 and 10A of the two computer light-emitting fans can be tightly and reliably connected together by the snap-fitting part 13 and the snap-fitting part 14. For example, in an embodiment shown in FIG. 2, the snap-fitting part 13 is a sliding clip and the snap-fitting part 14 is a sliding groove; in other preferred embodiments, the snap-fitting part 13 can be a dovetail block and the snap-fitting part 14 is a dovetail groove.

The sliding member 31 can be slidably disposed on the outer frame 10 and is located on the same side of the first electrical connection portion 11 and the second electrical connection portion 12. The sliding electrical connector 30 can slide to a first position (see FIG. 4) and a second position (see FIG. 3). The third electrode 32 is located on a side surface facing the outer frame 10 (therefore, it is shown in dotted lines in FIG. 1). As shown in FIG. 3, the third electrodes 32 of the sliding electrical connector 30 in the second position electrically connect the second electrodes 121 of the second electrical connection portion 12 of the outer frame 10 and the first electrodes 111 of the first electrical connection portion 11 of another outer frame 10A connected thereto; as shown in FIG. 4, the sliding electrical connector 30 in the first position only electrically connects the second electrodes 121 of the second electrical connection portion 12 of the outer frame 10; the functions of the sliding electrical connector 30 include completing power supply, signal The signal transmission can also be used as a power switch. For example, FIG. 5 shows a schematic diagram of a use state of a plurality of computer light-emitting fans that can be connected in parallel according to the present invention, wherein three light-emitting fans are connected in parallel. The user can start (move the sliding electrical connector 30 to the second position) or stop (move the sliding electrical connector 30 to the first position) one or more of the plurality of computer light-emitting fans of the same type connected in parallel by moving the sliding electrical connector 30.

In a preferred embodiment of the present invention, a terminal cover 60 is further included to shield the unused second electrical connection portion 12 of the light-emitting fan. As shown in FIG. 3, when only two light-emitting fans are connected, the second electrical connection portion 12 of the second light-emitting fan is unused, and the terminal cover 60 can provide shielding and dustproof effects for the unused second electrical connection portion 12. The structure of the terminal cover 60 can be compared to the sliding electrical connector 30 and the power connector 40, and can be slidably arranged in the slide groove 15 of the outer frame 10, and shield the unused second electrical connection portion 12 of the light-emitting fan.

The power connector 40 includes a sliding housing 41, a plurality of fourth electrodes 411 disposed on the sliding housing 41, and a power cord 42. The power connector 40 is detachably disposed on the outer side of the outer frame 10. The fourth electrodes 411 can be in contact with the first electrodes 111 of the first electrical connection portion 11 to form an electrical connection. One end of the power cord 42 is electrically connected to the fourth electrodes 411. The other end of the power cord 42 can be configured with an electronic plug 43 or an electronic socket, such as a 4-pin electronic plug or an electronic socket, for connecting to an external power source, generally a fan-specific socket or plug connected to a computer motherboard.

In a preferred embodiment of the present invention, the sliding electrical connector 30 is provided with a light-emitting element 50, which is electrically connected to the third electrode 32. When the external power supply is normally supplied and the motor is driven to operate, the light-emitting element 50 is also driven by the external power supply to emit light, serving as a power indicator, so that the user can judge whether the external power supply is normally supplied or a fault occurs; preferably, the light-emitting element 50 is a light-emitting diode (LED), and the preferred implementation method includes a single-color light-emitting diode and a multi-color light-emitting diode. In another embodiment, the power connector 40 is also provided with a light-emitting element 50 and is electrically connected to the fourth electrode 411.

In a preferred embodiment of the present invention, the first electrode 111 and the second electrode 121 are preferably spring-pin-type elastic electrodes (as shown in FIG. 1 ), and another preferred embodiment of the first electrode 111 and the second electrode 121 may also be spring-type elastic electrodes. The third electrode 32 and the fourth electrode 411 are preferably gold fingers. Since the surface electroplating layer of the gold finger is easily oxidized or worn, resulting in poor contact, which in turn causes the failure of power or electrical signal transmission, the sliding electrical connector 30 and the power connector 40 of the present invention are both detachable designs. When the above-mentioned oxidation or wear problems occur after a period of use, the problem can be solved by simply replacing the sliding electrical connector 30 and the power connector 40. There is no need to replace or discard the entire computer light fan, which can extend the service life of the computer light fan and avoid waste.

In a preferred embodiment of the present invention, the number of the first electrode 111, the second electrode 121, the third electrode 32 and the fourth electrode 411 corresponds to each other and is at least two. On the other hand, one embodiment of the first electrode 111, the second electrode 121, the third electrode 32 and the fourth electrode 411 is used to transmit power, including power for driving the motor and the light-emitting element 50; in another embodiment, it is used to transmit power and signals.

In a preferred embodiment, the sliding member 31 of the sliding electrical connector 30 and the sliding housing 41 of the power connector 40 are realized by a structure or means equivalent to the tail groove. Taking the sliding member 31 of the sliding electrical connector 30 as an example, as shown in FIG. 6 and FIG. 7, the sliding member 31 of the sliding electrical connector 30 is provided with side wings 311 on both sides parallel to the sliding direction, and a side wall 311 is provided on the outer side of the outer frame 10. The slide groove 15, the sliding member 31 and the sliding housing 41 corresponding to the side wing 311 are made of plastic (for example, made by plastic injection molding technology), so the side wing 311 of the sliding member 31 can be easily buckled in the slide groove 15 by the elasticity of the plastic, so the sliding member 31 of the sliding electrical connector 30 and the sliding housing 41 of the power connector 40 can slide along the slide groove 15 and have the advantage of easy disassembly.

Please refer to Figure 8. In a preferred embodiment, the width of the sliding member 31 of the sliding electrical connector 30 is the same as the cross-sectional width of the outer frame 10, which means that the outer surface of the sliding member 31 is preferably flush with the outer surface of the outer frame 10.

Finally, please refer to Figure 9, which is another schematic diagram of the use of multiple computer light fans that can be connected in parallel according to the present invention, showing the state of multiple computer light fans before being connected in parallel. Figure 9 takes three computer light fans as an example, wherein the first light fan is used to directly connect to an external power source to obtain the required power, and can also be electrically connected to an external signal source to obtain a control signal for controlling the light color. The first light fan F1 is equipped with a power connector 40 and a sliding electrical connector 30, the second light fan F2 is equipped with a sliding electrical connector 30, and the third light fan F3 is not equipped with a power connector 40. The sliding electrical connector 30 is only provided with a terminal cover 60 at the second electrical connection portion 12. After the first light-emitting fan F1, the second light-emitting fan F2 and the third light-emitting fan F3 are connected to each other, the sliding electrical connector 30 only needs to be moved to the second position to complete the power parallel connection and signal connection and transmission of the first light-emitting fan F1, the second light-emitting fan F2 and the third light-emitting fan F3. The assembly and operation are easy.

Although the present invention has been disclosed through the above-mentioned embodiments, it is not intended to limit the present invention. Anyone familiar with similar techniques can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be subject to the definition of the claims attached to this specification.
