In some embodiments, the electrical connector 140 includes a fixing hole 149, and the electrical connector 140 can be fixed to the fan assembly 110 by passing a fastener (not shown) such as a screw through the fixing hole 149.
As shown in fig. 2, the electrical connector 140 is configured to electrically connect with the electrical contacts 124 of the circuit board 120, and the guiding structure 150 is configured to guide and position the electrical connector 140 such that the electrical connector 140 is aligned with the electrical contacts 124 for electrical connection. Specifically, the guiding structure 150 has an opening 151 facing the electrical contact 124, the opening 151 being configured to receive the electrical connector 140. The electrical connector 140 is a contact connector configured to enter the opening 151 and contact the electrical contacts 124 of the circuit board 120.
As shown in fig. 2, the electrical connector 140 includes a housing 141 and a plurality of pins 142, wherein the bottom of the housing 141 has a boss 143, and the pins 142 are disposed on the boss 143. The opening 151 of the guiding structure 150 is configured to receive the boss 143, and the pins 142 on the boss 143 are aligned with and contact the electrical contacts 124 of the circuit board 120.
As shown in fig. 2, in some embodiments, the guiding structure 150 surrounds the electrical contacts 124 to form an opening 151, and the shape of the opening 151 matches the shape of the bump 143. When the protrusion 143 is located in the opening 151, the pins 142 of the electrical connector 140 and the electrical contacts 124 of the circuit board 120 are covered by the guiding structure 150 and are not exposed, so that the dustproof effect is achieved, and the appearance quality of the product is also improved.

When the boss 143 of the electrical connector 140 is located in the opening 151 of the guiding structure 150, the stopping portion 152 is configured to abut against two sides of the boss 143, so as to prevent the electrical connector 140 from being pressed down excessively to damage the pin 142.
As shown in fig. 2, in some embodiments, the housing 141 of the electrical connector 140 has a mounting surface 144, the mounting surface 144 and the protrusion 143 are located on two opposite sides of the housing 141, and the electrical connector 140 is mounted to the fan assembly 110 in a direction in which the mounting surface 144 abuts against the fan assembly 110 upward.
As shown in fig. 2, in some embodiments, mounting face 144 has a plurality of recesses 145, each recess 145 having an open end 146 located at a side of housing 141. The electrical connector 140 further includes a plurality of wires 147, the wires 147 being disposed in the recess 145 and extending laterally from the recess 145 through the open end 146.
As mentioned above, the wires 147 are configured to electrically connect the corresponding pins 142 and to electrically connect other components (not shown) such as the heat dissipation fan 112 and/or the LED lamp, and the electrical connector 140 receives the power from the circuit board 120 and then sequentially transmits the power to the other components such as the heat dissipation fan 112 and/or the LED lamp through the pins 142 and the wires 147.
Referring to fig. 3, in some embodiments, each pin 142 includes a first extending portion 142a and a second extending portion 142b connected to each other, the first extending portion 142a protrudes from the bottom surface of the boss 143, the second extending portion 142b extends at an angle from the first extending portion 142a (e.g., the second extending portion 142b extends perpendicular to the first extending portion 142 a), and the bottom surface of the second extending portion 142b is configured to contact the corresponding electrical contact 124. With the above-mentioned structure configuration, the pins 142 and the corresponding electrical contacts 124 have a larger contact area, so that the reliability of the connection between the electrical connector 140 and the electrical contacts 124 can be improved.
As shown in fig. 3, in some embodiments, the bottom surface area of the second extension portion 142b of the pin 142 is smaller than the area of the corresponding electrical contact 124, so that even if the position of the electrical connector 140 is slightly deviated (for example, the pin 142 and the electrical contact 124 are misaligned due to the manufacturing tolerance of the electrical connector 140 or the guiding structure 150), the pin 142 of the electrical connector 140 can still be reliably contacted with the electrical contact 124 under the guidance of the guiding structure 150.
Referring to fig. 4, in the assembling process, the boss 143 enters the opening 151 and slides along the inner wall 153 of the opening 151 until both sides of the boss 143 abut against the stopper 152, and at this time, the pins 142 disposed on the boss 143 contact the electrical contacts 124. In some embodiments, the sum of the height of the bump 143 and the height of the pin 142 is substantially equal to the height of the guiding structure 150 minus the height of the electrical contact 124.
As shown in fig. 4, when the protrusion 143 is located in the opening 151, the guiding structure 150 can limit the displacement of the electrical connector 140 in the direction X, Y parallel to the upper surface of the circuit board 120, so that each pin 142 of the electrical connector 140 can be aligned with the corresponding electrical contact 124 for electrical connection. In addition, the electrical connector 140 is stopped by the stopping portion 152 and cannot be further lowered, in other words, the stopping portion 152 can limit the displacement of the electrical connector 140 in the direction Z, which is the normal direction of the upper surface of the circuit board and is perpendicular to the direction X, Y, so as to prevent the electrical connector 140 from being pressed down excessively to damage the pins 142.

Before the electrical connector 140 is inserted into the guiding structure 150, if the protrusion 143 is slightly deviated from the position right above the opening 151, the protrusion 143 can smoothly enter the opening 151 under the guidance of the inclined surface 554, so that the pins 142 disposed on the protrusion 143 are aligned with and contact the corresponding electrical contacts 124.
It should be noted that the number and the position of the inclined surfaces 554 are not limited to those shown in fig. 5, and the inclined surfaces 554 may be disposed on all edges of the opening 151 according to practical requirements.
