Technical Field
[0001] This utility model relates to the field of connectors and circuit boards, and particularly to a bidirectional connector and circuit board. Background Technology
[0002] In the current fan industry, circuit boards are usually mounted on one side of the fan frame base, either the front or the rear. Circuit components that control and drive the fan are set on the circuit board. Through the planning and design of the circuit board, the fan can produce a variety of functions.
[0003] However, with the development of technology, the requirements for fans are becoming more and more numerous. Within the existing space of a fan, no matter how miniaturized the electronic components are or how much the circuit layout utilization is improved, the problem of insufficient circuit board space will eventually be faced. Insufficient circuit board space means that further compromises must be made on the functions.
[0004] Therefore, how to address and improve the current problem of insufficient space on fan circuit boards is the direction that the designers of this project and related manufacturers in this industry urgently want to study and improve. Utility Model Content
[0005] To address the aforementioned issues, this invention provides a bidirectional connector that fully utilizes the existing space of the fan, arranges multiple circuit boards at different positions on the fan frame base, and then electrically connects the multiple circuit boards via a connector.

Detailed Implementation
[0023] The above-mentioned objectives of this utility model and its structural and functional characteristics will be described with reference to the preferred embodiments shown in the accompanying drawings.
[0024] Please see Figure 1A , Figure 1B and Figure 1C The figures shown are perspective schematic diagrams (a), (b), and cross-sectional schematic diagram of the bidirectional connector of this utility model. This utility model provides a bidirectional connector 1, which mainly includes a body 11 and a plurality of pins 12. The specific structure of the bidirectional connector 1 will be described in detail below.
[0025] The main body 11 has a top end 111, a bottom end 112, and a side wall 113 located in the middle section between the top end 111 and the bottom end 112. In this embodiment, the top end 111 and the bottom end 112 are planar. The side wall 113 defines a first arcuate side 113A and a second arcuate side 113B. The curvatures of the first arcuate side 113A and the second arcuate side 113B are different. This structure has a foolproof effect during subsequent installation, effectively avoiding incorrect installation direction. In this embodiment, the first arcuate side 113A also has a groove 1131. The groove 1131 can be selectively manufactured. The groove 1131 can reduce the amount of material of the entire main body 11, thereby reducing weight and manufacturing costs. The material of the main body 11 is a thermoplastic non-conductive material, such as plastic or nylon.
[0026] Each of the plurality of pins 12 has a first contact portion 121, a second contact portion 122, and a conductor portion 123 located between the first and second contact portions 121 and 122. The pins 12 are sequentially inserted into the main body 11 and are not connected to each other. The first contact portion 121 of the pin 12 protrudes from the top end 111 of the main body 11, and the second contact portion 122 of the pin 12 protrudes from the bottom end 112 of the main body 11. The conductor portion 123 of the pin 12 is embedded in the main body 11. The main body 11 can be fixed to the pins 12 by covering or embedding injection, or holes sufficient for the pins 12 to be inserted can be pre-drilled and then combined by a tight fit. In addition, in this embodiment, the number of pins 12 is three, and they are arranged in a staggered manner. The overall number and arrangement of pins 12 are mainly determined according to the usage requirements and circuit planning, and are not limited thereto.
[0027] Please see Figure 2A , Figure 2B and Figure 2C The figures shown are an exploded view, a cross-sectional view (I), and a cross-sectional view (II) of the circuit board of this utility model attached to the fan frame base. Please refer to both views simultaneously. Figure 1A , Figure 1B and Figure 1C As shown, the circuit board 2 of this utility model mainly includes a first circuit board 21 and a second circuit board 22, and the first circuit board 21 and the second circuit board 22 are respectively disposed on the upper and lower sides of the base 31 of the fan frame 3.
[0028] The following will detail how the circuit board 2 is set to the fan housing 3, the structure of the fan housing 3, and the specific combination of the circuit board 2, the bidirectional connector 1, and the fan housing 3.
[0029] First, let’s describe the fan frame 3. The fan frame 3 has a base 31 in the center. The base 31 has a first receiving groove 311 and a second receiving groove 312 on both sides. The base 31 also has a connector mounting hole 313 between the first receiving groove 311 and the second receiving groove 312. In this embodiment, the shape of the connector mounting hole 313 matches the body 11 of the bidirectional connector 1, so that the bidirectional connector 1 can be smoothly and securely installed (embedded, embedded) in the connector mounting hole 313.
[0030] Although the above embodiments are illustrated using axial fans, they are not limited thereto and can also be used with centrifugal fans or other types of fans. The type of fan is not the focus of this utility model, so it will not be described in detail here.
[0031] The first circuit board 21 has a first receiving portion 211, and the second circuit board 22 has a second receiving portion 221. The first circuit board 21 is disposed in the first receiving groove 311 and the first receiving portion 211 is connected to the first contact portion 121. The second circuit board 22 is disposed in the second receiving groove 312 and the second receiving portion 221 is connected to the second contact portion 122. The first and second circuit boards 21 and 22 can be single-layer boards or multi-layer boards, and electronic components that achieve various functions of the fan are disposed on the surfaces of the first and second circuit boards 21 and 22.
[0032] It is clear that this utility model makes full use of the space on the upper and lower sides of the base 31 to make the first and second receiving slots 311 and 312 respectively to receive the first and second circuit boards 21 and 22. The first and second circuit boards 21 and 22 are electrically connected through the bidirectional connector 1. The circuit space is doubled and greatly increased by the two circuit boards, thereby realizing a fan with more diversified functions. In addition, when the fan is repaired in the future, only the damaged part can be replaced, achieving the advantages of expanded space and convenient maintenance.
[0033] In summary, the advantages of this utility model are:
[0034] 1. Increase circuit setup space;
[0035] 2. Easy to maintain.
[0036] The present invention has been described in detail above. However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made based on the present invention should still fall within the patent coverage of the present invention.
