Abstract

The invention discloses a hard disk device, and belongs to the field of hard disk design. The hard disk device comprises a sealing component, a printed circuit board and a hard disk base. The surface of the sealing component is provided with a hole. The surface of the hard disk base is provided with an installing slot. The printed circuit board is fixed in the installing slot and electrically connected with the hard disk base. The sealing component covers the installing slot. The printed circuit board is arranged in a space formed by the sealing component and the installing slot. The hard disk interface on the printed circuit board is communicated to the outside through the hole. The hard disk interface is contacted with the sealing component, and the contact part between the hard disk interface and the sealing component is sealed so that the space formed by the sealing component and the installing slot is enabled to be isolated from the outside. According to the hard disk device, the hard disk interface of the printed circuit board is ensured to be connected with equipment, and air is ensured not to enter the installing slot to corrode the circuit on the printed circuit board so that gold plating on the circuit of the printed circuit board is not required, the manufacturing process of the hard disk device is simplified, and manufacturing cost is also reduced.

Description

technical field [0001] The invention relates to the field of hard disk design, in particular to a hard disk device. Background technique [0002] The hard disk device is one of the main memories for storing data, and is generally plugged into the device for the device to store or read data.
