[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] In order to facilitate the external power connection of the fan and improve the reliability of the electrical connection, the technical solution proposes a connector, including: The fan frame 100 is provided with a control module; The conductive sheet 200 has a fixed end and a connecting end, wherein the fixed end is electrically connected to the control module, and the connecting end extends along the radial direction of the fan frame 100 and passes through the outer side wall of the fan frame 100; The socket 300 is disposed on the outer wall of the fan frame 100 , and the connecting end is engaged with the socket 300 and electrically connected.

[0023] In the technical solution of the present invention, a conductive sheet 200 is provided on the fan frame 100 to be electrically connected to the control module. Compared with the use of wires, the strength is improved, damage to the internal circuit of the fan is prevented, and the reliability is improved. In addition, the connecting end of the conductive sheet 200 is fixed to the socket 300 by snap-fitting, and the socket 300 is connected to the external circuit. This facilitates the connection of the fan to the external circuit, facilitates the subsequent disassembly and maintenance of the fan, and improves the flexibility and maintainability of the fan.

[0024] like Figures 1 to 8In one embodiment of the present invention, the fan frame 100 is the basic structure of the fan. A control module is installed on the fan frame 100. The control module can be in the form of a control circuit board. The control module can be arranged at the center of the fan frame 100. The control module is connected to the motor of the fan to control the operation of the motor to adjust the speed of the fan, etc. A conductive sheet 200 is arranged on the fan frame 100. The conductive sheet 200 can be a metal sheet structure such as a copper sheet or an aluminum sheet. The conductive sheet 200 has a relative fixed end and a connecting end, wherein the fixed end is fixed to the control module by welding or plugging and is connected to the circuit on the control module, and the connecting end extends along the radial direction of the fan frame 100 and passes through the outer side wall of the fan frame 100 in the radial direction. A socket 300 is arranged on the outer side wall of the fan frame 100. The socket 300 can be provided with a plug hole, and a conductive structure is arranged in the plug hole. The socket 300 is connected to an external power supply, and the connecting end of the socket 300 and the conductive sheet 200 can be The fan is fixed by snap-fitting to realize electrical connection between the external power supply and the control module. In addition, the socket 300 can be unplugged from the conductive sheet 200 to realize power off. The snap-fitting connection can facilitate the disassembly of the fan, facilitate the subsequent maintenance and replacement, and improve the flexibility and maintainability of the system. In addition, the conductive sheet 200 is used to replace the wire in this solution, which improves the structural strength of the internal circuit of the fan and ensures the reliability of long-term use. The conductive sheet 200 can have a larger contact area, which helps to reduce the risk of resistance and poor contact. In addition, in another embodiment, the conductive sheet 200 can be connected in a detachable manner. The conductive sheet 200 can be connected to the control module by plugging. A through hole can be set on the outer wall of the fan frame 100, and the conductive sheet 200 can be inserted into the through hole. A buckle 318 structure can be set in the through hole to fix the conductive sheet 200. Such a setting can also facilitate the replacement of the conductive sheet 200 when it is damaged, further improving the convenience of maintenance.

[0025] In addition, in other embodiments, in order to further improve the reliability of the electrical connection, a sealing structure can be provided between the socket 300 and the conductive sheet 200. For example, a sealing rubber ring can be provided at the edge of the socket 300 facing the fan frame 100. At the position where the conductive sheet 200 passes through the fan frame 100, a waterproof glue is provided between the outer side wall of the conductive sheet 200 and the fan frame 100. When the conductive sheet 200 is engaged with the socket 300, the sealing rubber ring is sealed against the outer side wall of the fan frame 100. Since the conductive sheet 200 and the outer side wall of the fan frame 100 are also sealed, the position where the conductive sheet 200 and the socket 300 are engaged will be sealed, thereby preventing water vapor from entering the connection position between the conductive sheet 200 and the socket 300, thereby ensuring that a good electrical connection can be maintained even in a humid or dusty environment.

[0026] like Figure 4 and Figure 5In one embodiment of the present invention, the socket 300 comprises: The housing 310 is disposed on the outer wall of the fan frame 100 , and a slot 311 is disposed on a side of the housing 310 facing the fan frame 100 ; The conductive terminal 320 is used to connect to an external power source. The conductive terminal 320 has a conductive portion 321 . The conductive portion 321 is disposed in the slot 311 . The conductive sheet 200 is plugged into the slot 311 and is electrically connected to the conductive portion 321 .

[0027] In this embodiment, the socket 300 includes a housing 310, which is made of insulating material. The housing 310 is detachably mounted on the outer wall of the fan frame 100. A slot 311 is arranged on the side wall of the housing 310 facing the fan frame 100. A conductive terminal 320 is arranged in the slot 311. The conductive terminal 320 can be connected to a power source through a wire. A conductive portion 321 is arranged on the conductive terminal 320. The conductive portion 321 can be attached to the inner surface of the slot 311. The conductive sheet 200 can be inserted into the slot 311 and fit with the conductive portion 321 to achieve electrical connection. A matching buckle 318 can be arranged on the conductive sheet 200 and in the slot 311, so that the conductive sheet 200 can be firmly fixed in the slot 311 to ensure the reliability of the connection. In other embodiments of the present invention, an LED light can also be arranged on the housing 310. The LED light is arranged on the line from the conductive terminal 320 to the external power source. The state of the LED light is used to determine whether the line is on or off, which helps the user to quickly determine the state of the fan.

[0028] In another embodiment of the present invention, a plurality of the conductive sheets 200 may be provided, and a plurality of conductive terminals 320 may be provided correspondingly. Each conductive sheet 200 is connected to a conductive terminal 320. Some conductive sheets 200 serve as input ends of power supply signals, and some conductive sheets 200 may serve as input ends of control signals or detection signals. In order to prevent the socket 300 from being inserted into the wrong position when being plugged in, the outer circumferential dimensions of each conductive sheet 200 may be different, and each conductive sheet 200 has a slot 311 that matches its outer circumferential dimensions. This can prevent mistakes and prevent damage to the fan caused by incorrect insertion.

[0029] like Figure 7 and Figure 8In one embodiment of the present invention, a protrusion 400 is provided on the side wall of one of the conducting portion 321 and the connecting end, and a groove 500 is provided on the other side wall, and the protrusion 400 is engaged with the groove 500. In the summary of this scheme, the protrusion 400 can be provided on the side wall of the conducting portion 321, and the groove 500 can be provided on the outer side wall of the connecting end. When the connecting end is inserted into the slot 311, the protrusion 400 can be engaged with the groove 500. The mutual limitation of the protrusion 400 and the groove 500 prevents the connecting end from being separated from the slot 311. When it is necessary to disassemble, it is only necessary to apply a greater force to deform the periphery of the protrusion 400 or the groove 500, so that the connecting end can be pulled out of the slot 311. The above structure can improve the reliability of the connection between the conductive terminal 320 and the conductive sheet 200, thereby ensuring the reliability of the fan operation. In addition, in order to further improve the reliability, a plurality of protrusions 400 can be provided, and a plurality of grooves 500 can also be provided correspondingly, through a multi-point engaging structure. This can increase the stability of the connection.

[0030] like Figure 7 In one embodiment of the present invention, the conductive terminal 320 further includes a clamping portion 322, which is bent and connected to opposite sides of the conductive portion 321, and the clamping portion 322 cooperates with the conductive portion 321 to clamp the connection end; the clamping portion 322 can be integrally bent and formed with the conductive portion 321, and a clamping space is defined between the clamping portion 322 and the conductive portion 321. When the connection end of the conductive sheet 200 begins to be inserted, the clamping portion 322 will abut against the conductive sheet 200 so that the conductive sheet 200 and the conductive portion 321 are closely fitted. During the insertion process, the clamping portion 322 can be elastically deformed relative to the conductive portion 321, so that the conductive sheet 200 is always closely fitted with the conductive portion 321, thereby ensuring the reliability of the connection. In addition, when the conductive sheet 200 needs to be pulled out, due to the presence of the protrusion 400 and the groove 500, the clamping portion 322 needs to be deformed before it can be detached, which is also conducive to improving the reliability of the connection. In addition, in order to ensure smooth insertion of the conductive sheet 200, a guiding structure may be provided at the entrance of the slot 311. Specifically, protruding rib structures may be provided on the peripheries of the opposite sides of the entrance of the slot 311. The rib structures may extend toward the space between the clamping portion 322 and the conducting portion 321. When the conductive sheet 200 is inserted, it may be inserted into the space between the clamping portion 322 and the conducting portion 321 under the guidance of the rib structure, thereby preventing the conductive sheet 200 from interfering with the end face of the clamping portion 322 or the conducting portion 321 and being difficult to insert, which is beneficial to improving the convenience of use.

[0031] like Figure 4In order to reduce the overall radial size of the connector, in one embodiment of the present invention, a threading channel 312 is provided on the housing 310, and the threading channel 312 extends along the axial direction of the fan frame 100 for the wire to pass through, and the conductive terminal 320 further includes a connecting portion 323, the connecting portion 323 is provided on the conductive portion 321, and one end of the connecting portion 323 extends into the threading channel 312 to connect with the wire; wherein, openings may be provided at both ends of the extending direction of the threading channel 312, the connecting portion 323 may be integrally bent and formed with the conductive portion 321, and the connecting portion 323 is inserted into the threading channel 312, and the wire may extend into the threading channel 312 along the axial direction of the fan frame 100. 12 and fixed with the connecting portion 323 by welding or the like. With such arrangement, compared with the conventional socket 300 structure, the wire in the present solution extends along the axial direction of the fan frame 100. Therefore, the radial dimension of the socket 300 along the fan frame 100 can be made smaller, thereby reducing the size of the connector. When the connector is installed, the wire can be bent along the outer peripheral wall of the fan frame 100 to follow the line. No space needs to be reserved in the radial direction of the fan frame 100 for the wire to bend, thereby reducing the installation space required for the connector. In addition, the threading channel 312 can also provide protection for the connection point between the wire and the connecting portion 323, thereby improving the reliability of the connection. In the case of setting up multiple conductive terminals 320, the slot 311 can be arranged in parallel on one side of the threading channel 312 along the axial direction of the fan frame 100. Multiple wires can be inserted into the threading channel 312 at the same time and respectively connected to different conductive terminals 320. This can maximize the space utilization of the threading channel 312. In addition, multiple wire grooves can be recessed in the threading channel 312. The wire grooves extend along the axial direction of the fan frame 100. Each wire groove accommodates a wire. This can improve the insulation performance between adjacent wires.

[0032] like Figure 5 , Figure 6 and Figure 8 In one embodiment of the present invention, the housing 310 includes: The lower shell 313 is disposed on the outer side wall of the fan frame 100.

The slot 311 is disposed on one side of the threading groove 319. The upper shell 314 covers the wire threading slot 319 and is connected to the lower shell 313 .

[0033] In this embodiment, the housing 310 adopts a split design. The housing 310 includes an upper housing 314 and a lower housing 313 that are interlocked. The lower housing 313 is arranged on the outer wall of the fan frame 100. A threading groove 319 is arranged on the side of the lower housing 313 that is away from the fan frame 100. The two ends of the threading groove 319 in the extension direction are open and the top is also open. The slot 311 is arranged on one side of the threading groove 319. The upper housing 314 covers the lower housing 313 and closes the threading groove 319 and the slot 311. When assembling, the conductive terminal 320 can be first installed on the lower housing 313, and the conductive portion 320 can be installed on the conductive portion 320. 1 is embedded into the slot 311, the connecting portion 323 is bent and attached to the inner wall of the threading groove 319, and then the wire is connected to the connecting portion 323, and finally the upper shell 314 is buckled on the lower shell 313 to complete the assembly; it can be seen that the above structure can facilitate the assembly of the housing 310 and simplify the assembly process. In addition, in order to facilitate the subsequent maintenance, the upper shell 314 and the lower shell 313 can be fixed by a detachable connection such as screw connection. When maintenance is required, the upper shell 314 can be disassembled, and the wire and the conductive terminal 320 can be exposed, which is convenient for maintenance.

Specifically, grooves 500 are provided on two opposite side walls of the socket 300, and two spaced card bodies 600 are provided on the fan frame 100. During installation, the socket 300 can be pressed on the fan frame 100 so that the card body 600 is inserted into the groove 500 to fix the socket 300. In addition, the side wall of the groove 500 close to the fan frame 100 can be designed as an inclined surface, which extends obliquely from the bottom of the groove toward the side of the fan frame 100. When the socket 300 needs to be disassembled, it is only necessary to apply a force away from the fan frame 100 to the socket 300, and the card body 600 can slide out of the groove 500 along the inclined surface, which facilitates disassembly. Of course, the inclined surface can also be provided on the end surface where the card body 600 contacts the groove 500, so that the socket 300 can be quickly disassembled, which is not limited here.
