MOBILE HARD DISK AND ELECTROMAGNETIC INTERFERENCE RESISTANCE MOTHOD FOR MOBILE HARD DISK

摘要

A electromagnetic interference resistance method for mobile hard disk, the mobile hard disk comprises a hard disk (1) which has a electrically conductive shell, and a circuit board (2) which has a ground terminal, the shell of the hard disk (1) is electrically connected to the ground terminal of the circuit board (2). A mobile hard disk comprises a hard disk (1), a circuit board (2) which transforms the interface of the hard disk (1), and a case of the mobile hard disk, the hard disk (1) has mounting seats (11), the circuit board (2) has the ground terminal, the circuit board (2) and the hard disk (1) are fixed in the case of the mobile harddisk, the mobile hard disk also includes a connector, the connector has two terminals which conduct mutually, one of the two terminals electrically connects with the ground terminal of the circuit board (2), the other electrically connects with the mounting seat (11) of the hard disk (1). The mobile hard disk adopting the technical solution of the present invention sets the connector which electrically connects the ground terminal of the circuit board (2) to the shell of the hard disk (1) credibly, so the ability of electromagnetic interference resistance is improved.
