[0022] According to the first embodiment of the present invention, an input and output pin (I / O pin) of a detection chip 260 can be used on the motherboard to connect to the detection pin (DET), so that the detection chip 260 can (DET) to know whether the storage device 240 is inserted into the SATA interface socket 200. Furthermore, the detection chip 260 can be a super I / O device (Super I / O device) or a general purpose I / O device (general purpose I / P, GPIO) or a south bridge chip on the motherboard.

[0023] Obviously, when the storage device 240 is not inserted into the SATA interface socket 200, the detection pin (DET) of the SATA interface socket 200 will be pulled up (pull up) to a high level; otherwise, when the storage device 240 is inserted into the SATA interface socket 200 At this time, since the first grounding wire of the SATA interface plug 220 is connected to the ground voltage, the detection pin (DET) of the SATA interface socket 200 will be pulled down to a lo...

Abstract

A detector locates at a mainboard for detecting the connection of an exterior device and a socket. The detecting device includes a control chip, an upper pulling element, a socket and a testing chip. The detecting device is provided with a plurality of electric leads, which are divided into a first part, a second part and a third part, wherein, the first part is connected to the control chip for receiving and transferring data, the second part is connected with to a first voltage, and an upper pulling element is connected between the third part and a second voltage. The testing chip is provided with a input pin in bit connection to the third part, wherein, when the exterior device does not connect to the socket, the third part maintains at the second voltage; when the exterior device connects to the socket, the third part does not maintain at the second voltage. The invention can detect in real-time whether the external storage device is inserted in the SATA interface socket by selecting one of the three earthing electric leads defined by the SATA interface, which does not need the BIOS to detect the inserting of the external storage device.

Description

technical field [0001] The invention relates to a detection device, and in particular to a detection device capable of detecting a serial advanced technology attachment (serial advanced technology attachment, referred to as SATA) interface socket connected to an external device. Background technique [0002] Early storage media, such as hard disks or optical drives, used the Advanced Technology Attachment (ATA) interface to exchange data with the host. The data of this ATA interface is transmitted in parallel, so it is also called For the PATA interface. Recently, the Serial Advanced Technology Attachment (SATA) interface has gradually replaced the PATA interface as the main interface between the storage medium and the host. [0003] See Figure 1A , which shows a perspective view of a SATA interface connector (connector). The SATA interface connector includes a SATA interface plug (plug) 120 and a SATA interface socket (jack) 100 . Wherein, there are two openings in the ...
