The fan housing module 100 includes a base 110, a frame 120 and a circuit assembly 130. The base 110 and the frame 120 are combined into one body.
[0047] See also Figure 1 and Figure 2 The base 110 has a first body 111 and a first protection portion 112, and the first protection portion 112 is protruded from the outer surface 111a of the first body 111. The frame 120 has a second body 121 and a second protection portion 122, and the second protection portion 122 is protruded from the outer surface 121a of the second body 121. The second body 121 is combined with the first body 111 to form a shell 100a, and an accommodating space S is formed between the first protection portion 112 and the second protection portion 122.

The electrical connector 132 is electrically connected to the circuit board 131. The circuit board 131 is disposed in the housing 100a. The electrical connector 132 is located in the accommodating space S, so that the electrical connector 132 protrudes from the outside of the housing 100a to facilitate the electrical connector 132 to engage with another external electrical connector (not shown). The electrical connector 132 is protected by the first protection portion 112 and the second protection portion 122 to prevent the electrical connector 132 from being pulled or touched by improper external force and detached from the circuit board 131.
[0049] See also Figure 3 and Figure 4The circuit board 131 has a first conductive portion 131a and a second conductive portion 131b. The electrical connector 132 is connected to the first conductive portion 131a. The second conductive portion 131b is used to electrically connect the stator (not shown) so that the stator drives the rotor to rotate. In this embodiment, the first conductive portion 131a is located between the first protection portion 112 and the electrical connector 132. Preferably, the first conductive portion 131a and the electrical connector 132 The first protective portion 112 and the second protective portion 122 are clamped to increase the holding force of the first conductive portion 131a and the electrical connector 132 to the first protective portion 112 and the second protective portion 122. This can prevent the electrical connector 132 from being separated from the circuit board 131 or causing the electrical connector 132 to be disconnected from the circuit board 131 and form a short circuit when another external electrical connector (not shown) is plugged into or unplugged from the electrical connector 132.
[0050] See also Figure 2 and Figure 6 Preferably, the first body 111 has at least one first joint portion 111b, and the second body 121 has at least one second joint portion 121b, and the second joint portion 121b is embedded in the first joint portion 111b. When the second body 121 is combined with the first body 111 to form the shell 100a, the second joint portion 121b can be aligned with the first joint portion 111b, so that the frame 120 can be quickly combined with the base 110 into one. More preferably, the first joint portion 111b has a first through hole 111e, and the second joint portion 121b has a second through hole 121c. The first through hole 111e corresponds to and is connected to the second through hole 121c, so that a fixing member (not shown in the figure, such as a bolt, etc.) can be passed through the first through hole 111e and the second through hole 121c to prevent the frame 120 from being separated from the base 110.
[0051] See also Figure 2 and Figure 3 In the present embodiment, the first body 111 has a carrier 111c and a shaft seat 111d, the shaft seat 111d is protruding from the carrier 111c, and a bearing cylinder 140 is disposed on the shaft seat 111d.

The second conductive portion 131b of the circuit board 131 is disposed on the shaft seat 111d, and a distance D is provided between the second conductive portion 131b and the carrier 111c. The distance D can accommodate at least one electronic component (not shown) disposed on the second conductive portion 131b to increase the use space of the second conductive portion 131b for configuring the electronic component (not shown).
[0052] See also Figure 2 and Figure 3 A channel L is provided between the first body 111 and the second body 121, and the channel L is connected to the accommodating space S. In the present embodiment, the channel L is recessed in the second body 121, and the first conductive portion 131a of the circuit board 131 is disposed in the channel L. Preferably, the first conductive portion 131a is clamped by the first body 111 and the second body 121 to increase the holding force of the first conductive portion 131a held by the first protecting portion 112 and the second protecting portion 122.
[0053] See also Figure 1 , Figure 2 and Figure 5 Preferably, at least one limiting protrusion 112b is provided on the first surface 112a of the first protecting portion 112, and the limiting protrusion 112b is located between the first protecting portion 112 and the second protecting portion 122. The first conductive portion 131a has at least one limiting groove 131c, and the limiting protrusion 112a is locked in the limiting groove 131c, so that the first conductive portion 131a is limited to the first protecting portion 112. After the electrical connector 132 is plugged into another external electrical connector (not shown), when the other electrical connector is to be unplugged, the holding force of the first conductive portion 131a and the first protecting portion 112 is increased, and when the circuit assembly 130 is assembled on the base 110, the limiting protrusion 112a can be aligned with the limiting groove 131c to quickly position the electrical connector 132 on the first protecting portion 112.
[0054] See also Figure 3 , Figure 4 , Figure 7 Preferably, the second surface 112c of the first protecting portion 112 has at least one reinforcing rib 112d, and the reinforcing rib 112d is connected to the first body 111 to increase the structural strength of the first protecting portion 112, which can prevent improper external force from pressing the second protecting portion 122 or the electrical connector 132 and causing the first protecting portion 112 to be disconnected from the first body 111.
[0055] See also Figure 2 and Figure 4Preferably, the second protecting portion 122 has a first limiting rib 122a and a second limiting rib 122b, the first limiting rib 122a and the second limiting rib 122b are located between the first protecting portion 112 and the second protecting portion 122, along the first axial direction Y, the accommodating space S is located between the first protecting portion 112 and the second protecting portion 122, and along the second axial direction X intersecting with the first axial direction Y, the accommodating space S is located between the first limiting rib 122a and the second limiting rib 122b, when the electrical connector 132 is disposed in the accommodating space S, the electrical connector 132 can be restricted in the accommodating space S to prevent the electrical connector 132 from being separated from the first protecting portion 112 and the second protecting portion 122, thereby causing a short circuit between the electrical connector 132 and the circuit board 131.
[0056] See also Figure 8 , which is the second embodiment. The difference between the second embodiment and the first embodiment is that the first conductive portion 131a is not located between the first protecting portion 112 and the electrical connector 132, and only the electrical connector 132 is clamped by the first protecting portion 112 and the second protecting portion 122. Similarly, it can increase the holding force of the electrical connector 132 held by the first protecting portion 112 and the second protecting portion 122, and can prevent the electrical connector 132 from being separated from the circuit board 131 or causing a circuit break between the electrical connector 132 and the circuit board 131 when the electrical connector 132 is plugged in or unplugged from another external electrical connector (not shown).
[0057] See also Fig. 9 , which is the third embodiment, and the difference between the third embodiment and the first and second embodiments is that the second conductive portion 131b of the circuit board 131 is disposed on the carrier 111c to reduce the thickness of the fan housing module 100 so that the fan housing module 100 can be used in electrical appliances with narrow space.
