[0002] In the current fan field, a circuit board is usually installed on one side of the front or rear of the fan frame base singly, and circuit elements for controlling and driving the fan are arranged on the circuit board. Through the planning and design of the circuit board, the fan can generate diversified functions.

[0003] However, with the development of technology, more and more functions are required for fans. In the existing space of a fan, no matter how miniaturized the electronic components are and how much the utilization rate of the circuit layout is improved, the problem of insufficient circuit board space will eventually be faced. Insufficient circuit board space means that compromises must be made in further function selection.

[0004] Therefore, how to face up to and improve the problem of insufficient circuit board space in current fans is the direction that the inventors of this case and related manufacturers in this industry are eager to research and improve. Summary of the Invention

[0006] To achieve the above object, the present invention provides a bidirectional connector, which includes: a main body and a plurality of pins. The main body has a top end and a bottom end, which are respectively arranged at two opposite ends of the main body. The pins are inserted into the main body and are not connected to each other. Each of the pins has a first contact portion, a second contact portion, and a conductor portion located between the first and second contact portions. The first contact portion of the above-mentioned pin passes out from the top end, the second contact portion of the above-mentioned pin passes out from the bottom end, and the conductor portion of the above-mentioned pin is buried in the main body.

Detailed implementation manners

[0023] The above objects, structures and functional characteristics of the present invention will be described with reference to the preferred embodiments shown in the accompanying drawings.

[0024] Please refer to Figure 1A 、 Figure 1B and Figure 1C shown, which are respectively the three-dimensional schematic views (I), (II) and cross-sectional schematic view of the two-way connector of the present invention. The present invention provides a two-way connector 1, mainly including a body 11 and a plurality of pins 12. The specific structure of the two-way connector 1 will be described in detail below.

[0025] The body 11 has a top end 111, a bottom end 112 and a side wall 113 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 in a planar form. 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. Such a structure has an anti-misassembly effect during subsequent installation, effectively avoiding incorrect installation directions. In this embodiment, the first arcuate side 113A further has a groove 1131. The groove 1131 can be selectively made. The groove 1131 can reduce the material amount of the entire body 11, achieving the effects of reducing weight and production cost. The material of the above-mentioned body 11 is selected as a thermoplastic non-conductive material, such as plastic or nylon (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 penetrates out from the top end 111 of the main body 11, the second contact portion 122 of the pin 12 penetrates out from the bottom end 112 of the main body 11, and the conductor portion 123 of the pin 12 is embedded in the main body 11. The main body 11 can be fixedly combined with the pin 12 by means of coating or insert injection molding, or holes sufficient for inserting the pins 12 can be reserved first and then combined by means of 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 the pins 12 are mainly determined according to the usage requirements and circuit planning, and are not limited thereto.

[0029] First, the fan frame 3 will be described. There is a base 31 at the center of the fan frame 3. There is a first receiving groove 311 and a second receiving groove 312 on both sides of the base 31, and there is also a connector setting hole 313 between the first receiving groove 311 and the second receiving groove 312 on the base 31. In this embodiment, the shape of the connector setting hole 313 matches the main body 11 of the two-way connector 1, so that the two-way connector 1 can be smoothly and firmly installed (inserted, embedded) in the connector setting hole 313.

[0030] Although the above-described embodiments are described using an axial flow fan, it is not limited thereto. It can also be used in a centrifugal fan or other types of fans. The type of the fan is not the focus of the present invention, so it will not be elaborated 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 for achieving various functions of the fan are disposed on the surfaces of the first and second circuit boards 21 and 22.

[0032] It can be clearly understood that the present invention makes full use of the spaces on the upper and lower sides of the base 31, respectively manufactures the first and second receiving grooves 311 and 312 to receive the first and second circuit boards 21 and 22, electrically connects the first and second circuit boards 21 and 22 through the bidirectional connector 1, doubles the circuit space through two circuit boards, and greatly increases the number of functions of the fan. In addition, when the fan is repaired in the future, only the damaged part can be replaced, achieving the advantages of expanding space and facilitating maintenance.

[0033] In summary, the advantages of the present invention are as follows:

[0034] 1. Increase the circuit setting space;

[0035] 2. Facilitate maintenance.
