Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the embodiments, by Figure 1-4 An embedded computer motherboard is provided. The present invention includes a PCB motherboard 1, an expansion connection contact point 2 at one end of the PCB motherboard 1, an expansion connection frame 3 connected to the outside of the PCB motherboard 1, a locking pin extending to press against the PCB motherboard 1 on the outside of the expansion connection frame 3, a plug-in 4 with its end contacting the expansion connection contact point 2 inside the expansion connection frame 3, a buckle 5 fixedly provided on the outside of the expansion connection frame 3 to cooperate with the plug-in 4 and form a connection with an external socket, and a heat dissipation unit 6 provided on the outside of the expansion connection frame 3.

[0027] The connector 4 includes a connector frame 41 disposed inside the expandable connector frame 3. The end of the connector frame 41 is fixedly connected to a plug contact point 42 facing the buckle 5. The outside of the connector frame 41 is fixedly connected to an elastic contact piece 43 that is in contact with the expandable connector contact point 2 and forms an electrical connection with the plug contact point 42 on the other side.

[0028] Furthermore, the buckle 5 consists of an elastic compression piece and a locking block fixed to its exterior. The number of locking blocks is multiple, which can form a foolproof setting. The sides of the locking blocks are beveled.

[0029] Furthermore, the heat dissipation unit 6 includes a sliding frame 61 that is slidably connected to the expandable connecting frame 3. A miniature fan 62 is provided on the inner side of the sliding frame 61, and an elastic conductive plate 63 is fixedly connected to the bottom of the sliding frame 61.

[0030] The advantages of adopting the above-mentioned further solutions are that the heat dissipation effect is improved, the sliding bracket design facilitates installation, and the elastic conductive plate enhances heat conduction.

[0031] Furthermore, there are multiple elastic conductive plates 63 arranged in a front-to-back array, and the airflow generated by the micro fan 62 passes through the gaps between the elastic conductive plates 63.

[0032] Furthermore, the side of the expandable connecting frame 3 is provided with a power supply contact groove, and the inside of the power supply groove is provided with a fan power supply contact. The end of the sliding frame 61 is provided with an elastic power supply piece that is connected to the fan power supply contact and connected to the miniature fan 62. The air inlet direction and air outlet direction of the miniature fan 62 are the top and the side facing the elastic conductive piece 63, respectively.

[0033] Working principle:

[0034] The extension connector 3 makes the overall connection process more convenient, and at the same time, it works with the plug to make the plug end rotate.

[0035] The power supply harness of the PCB motherboard 1 can be directly plugged in through the connector 4. The elastic contact piece 43 on the outside of the connector bracket 41 presses against the expansion connection contact 2 to achieve electrical connection. The buckle 5 on the outside of the expansion connection bracket 3 connects with the external power supply harness. The buckle 5 is composed of an elastic pressing piece and an external locking block. The side of the locking block is beveled, which facilitates connection. Multiple locking blocks can form a foolproof setting. During the plugging process, the foolproof opening can effectively prevent incorrect plugging.

[0036] During operation, the heat dissipation unit 6 is connected to the expansion connector 3 via the sliding bracket 61. When the load on the PCB motherboard 1 is not large, the heat dissipation unit 6 can be removed to reduce the overall power supply load.

[0037] The fan power supply contact in the power supply contact slot on the side of the expansion connector 3 powers the miniature fan 62. The elastic power supply piece at the end of the sliding bracket 61 is connected to the fan power supply contact to ensure that the miniature fan 62 works normally. The air intake direction of the miniature fan 62 is the top, and the air outlet direction is towards the side of the elastic conductive piece 63. In addition, the elastic conductive piece 63 and the components on the surface of the PCB motherboard 1 are squeezed to transfer heat, thus achieving effective heat dissipation of the motherboard.
