The first fan connector 22 and the second fan connector 23 can respectively adapt to fans 33 with different sizes or types, so that the fan switching circuit board 20 can be compatible with fans 33 with different sizes or types. In the production process, the fan switching circuit board 20 is provided, so that one of the first fan connector 22 and the second fan connector 23 can be flexibly selected to be electrically connected with the adaptive fan 33 according to the product requirement, and therefore different circuit boards are not required to be provided for the fans 33 with different sizes or models respectively, the production cost is effectively reduced, and the production efficiency is improved.

Referring to fig. 7 and 8, the fan plug 32 may be plug-fit with the second electrical conductor 232. The fan 33 is electrically connected to the second electrical conductor 232 via the fan plug 32.

Illustratively, fig. 9 is an enlarged view at W in fig. 8. Referring to fig. 6 and 9, the second conductive body 232 has a columnar structure. The fan plug 32 comprises a hollow plug sleeve. The material of the plug sleeve is an electrically conductive metal material, such as, but not limited to, copper or copper alloy.

In some implementations, the front projection of the first fan connector 22 and the second fan connector 23 along the thickness direction X of the plate body 21 may be rectangular. The fan plug 32 includes a receiving hole, and a plug sleeve or plug post is disposed within the receiving hole.

In some examples, the fan plug 32 may plug with the first electrical conductor 222, or the plug sleeve or plug post may plug with the second electrical conductor 232 when plugged with the first fan connector 22 or the second fan connector 23.

In other examples, referring to fig. 6, the first fan connector 22 or the second fan connector 23 includes a receiving cavity 24. The first electrical conductor 222 or the second electrical conductor 232 is disposed in the corresponding receiving cavity 24.

In some implementations, the first fan connector 22 and the second fan connector 23 are disposed on the same mounting face 21a. The first fan connector 22 and the second fan connector 23 are located on the same side of the plate body 21. Therefore, when the fan module 10 including the fan-adapting circuit board 20 and the fan assembly 30 is installed in the chassis 110 of the server 100, the fan-adapting circuit board 20 is conveniently connected and fixed with the chassis in a case where the fan-adapting circuit board 20 is disposed close to the chassis 110.

In some examples, the plurality of first fan connectors 22 are equally spaced. A first distance L1 is provided between two adjacent first fan connectors 22. Any two first pitches L1 of all the first pitches L1 are equal. The plurality of fans 33, which are adapted to be connected with the first fan connector 22, are disposed at equal intervals therebetween, so that it is possible to advantageously improve the heat dissipation uniformity of the plurality of fans 33. Illustratively, referring to fig. 5, six first fan connectors 22 form five first pitches L1. Wherein, five first intervals L1 are equal to each other.

In some examples, at least two second pitches L2 among all second pitches L2 formed by the plurality of second fan connectors 23 are equal. Illustratively, referring to fig. 5, four second fan connectors 23 form three second pitches L2. Wherein, two second intervals L2 on both sides are equal.

Any two second pitches L2 of all the second pitches L2 are equal. The plurality of fans 33 which are adapted to be connected with the second fan connector 23 are also arranged at equal intervals, so that the uniformity of heat dissipation of the plurality of fans 33 can be improved. Illustratively, four second fan connectors 23 form three second pitches L2. Wherein, the three second pitches L2 are equal to each other.

In some examples, the first spacing L1 between two adjacent first fan connectors 22 is not equal to the second spacing L2 between two adjacent second fan connectors 23, so that the first fan connectors 22 and the second fan connectors 23 can be ensured to have a foolproof effect. When the first fan connectors 22 are electrically connected with the corresponding fan assemblies 30, the fan plugs 32 of the fan assemblies 30 can only be plugged with the first fan connectors 22 smoothly, and cannot be plugged with the first fan connectors 22 erroneously. Likewise, when the second fan connector 23 is electrically connected to the adapted fan assembly 30, the fan plug 32 of the fan assembly 30 can only be plugged into the respective second fan connector 23 smoothly, without being plugged into the respective second fan connector 23 erroneously. The design mode that first interval L1 and second interval L2 are unequal can effectively avoid appearing pegging graft the mistake and lead to fan module 10 not to satisfy the condition of actual requirement, can effectively improve equipment rate of accuracy and equipment work efficiency simultaneously.

Illustratively, the first spacing L1 between two adjacent first fan connectors 22 may be 66.4 millimeters (mm). Accordingly, the spacing between adjacent fans 33 in the fan assembly 30 may be 66.4 millimeters (mm).

Illustratively, at least a portion of all second pitches L2 formed by the plurality of second fan connectors 23 may be 89.6 millimeters (mm). Accordingly, the spacing between at least a portion of the adjacent two fans 33 of the fan assembly 30 may be 89.6 millimeters (mm) among all fans 33.

In some examples, a first fan connector 22 is disposed between two adjacent second fan connectors 23 such that the two adjacent second fan connectors 23 may be separated by the first fan connector 22. For example, one or more first fan connectors 22 may be provided between two adjacent second fan connectors 23. For example, referring to fig. 5, four second fan connectors 23 and six first fan connectors 22 are provided on the board body 21. A fan assembly 30, which is compatible with the first fan connector 22 and includes six fans 33, may be connected with the fan-adapter circuit board 20. Alternatively, a fan assembly 30, which is adapted to the second fan connector 23 and includes four fans 33, may be connected to the fan-adapter circuit board 20.

Taking the position of fig. 5 as an example, from left to right, a first fan connector 22 may be disposed between the first second fan connector 23 and the second fan connector 23. Two first fan connectors 22 may be provided between the second fan connector 23 and the third second fan connector 23. A first fan connector 22 may be provided between the third second fan connector 23 and the fourth second fan connector 23.

In some implementations, a plurality of first fan connectors 22 are spaced along the first marker line 40. The plurality of second fan connectors 23 are spaced apart along the second index line 50. The first and second marking lines 40 and 50 may be disposed in parallel. The first mark line 40 and the second mark line 50 may be both straight lines. The first fan connector 22 and the second fan connector 23 are arranged in a staggered manner, which is beneficial to accurately identifying the first fan connector 22 and the second fan connector 23 by an image identification device (such as an industrial camera) in the production process, so as to assist in assembling the fan assembly 30 with the first fan connector 22 or the second fan connector 23, and further facilitate reducing the connection error of the fan assembly 30 with the fan switching circuit board 20.

In some implementations, the first fan connector 22 and the second fan connector 23 are disposed at an edge region of the plate 21. Typically, the edge region of the board body 21 is not provided with associated electronics. In this embodiment, the first fan connector 22 and the second fan connector 23 are disposed in the edge area of the board 21, so that the installation space on the board 21 can be fully utilized, and the utilization rate of the board 21 can be improved.

In some implementations, fig. 10 schematically illustrates a side view structure of the fan-interposer circuit board 20 of the present application. Referring to fig. 10, the first fan connector 22 and the second fan connector 23 are disposed on the same side of the board 21. The heights H1 and H2 of the first fan connector 22 and the second fan connector 23 are different along the thickness direction X of the board 21, so that the first fan connector 22 and the second fan connector 23 can be effectively distinguished by taking the heights H1 and H2 of the first fan connector 22 and the second fan connector 23 as reference conditions, so as to reduce the possibility of connecting the fan assembly 30 and the fan switching circuit board 20 in error.
