Description

Technical Field

[0001] The invention relates to the field of hard disk installation, and in particular to a hard disk installation module, a chassis and an electronic device. Background Art

[0002] PCB (Printed Circuit Board) is the support for electronic components and provides a basis for the electrical connection of electronic components. The connector on the PCB realizes the transmission of signals or currents through the contact connection between the male end and the female end.

[0003] Wire-end connectors and board-end connectors are two common types of connectors. Wire-end connectors are designed for the end connections of wires or cables, and are mainly used to achieve connections between wires or between wires and devices; board-end connectors are often directly mounted on printed circuit boards, generally in the form of pins or sockets, which can be directly soldered or fixed on the PCB board through pads and slots for connection with other electronic components or cables; wire-end connectors are more flexible and do not require high space, but they need to be disassembled and cannot be fixed to the board, resulting in poor connection stability; although the board-end connector has good connection stability with the board, it has high requirements for the precision of the plug-in and mating process.

[0004] In the related art, when installing devices such as hard disks, the board-end connector is generally installed on a vertically arranged board, the slot of the board-end connector extends in the horizontal direction, the hard disk is arranged in the vertical direction, and installed in the slot in the horizontal direction. In order to achieve heat dissipation of the board-end connector and the hard disk, it is also necessary to open ventilation slots on the board. Since the ventilation slots occupy the area of ​​the board, when the same number of hard disks are installed, the area of ​​the board needs to be increased, thereby occupying more space; the airflow can only pass through the ventilation slots, resulting in poor heat dissipation effect; and since the position of the board-end connector is fixed, the installation of the hard disk is limited and the scope of application is small.

[0067] The hard disk installation module places the board 1 in the heat dissipation channel, and the board 1 extends along the airflow direction of the heat dissipation channel, so that the airflow can flow through the surface of the board 1; because the airflow passes through the surface of the board 1, there is no need to open ventilation slots on the board 1, which reduces the area of ​​the board 1 occupied by the ventilation slots, thereby facilitating the miniaturization of the board 1 and avoiding the problem in the related art that the airflow can only pass through the ventilation slots, resulting in a small gas flow rate and poor heat dissipation effect. The hard disk installation module sets the board 1 to be perpendicular to the airflow direction of the heat dissipation channel, so that the airflow can pass along the entire surface of the board 1, the gas flow rate is large, and the heat dissipation effect is significantly improved; and by connecting The connector body 2 is provided with an input connection terminal 211 and an output connection terminal 212.
