Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a connector module and, more particularly, to a connector module having a function of detecting the connection of an electronic device.

2. Description of the Related Art

Connectors of most electronic devices do not have a detecting function. When an external device is plugged into an electronic device, the communication protocol between the electronic device and the external device or programs capable of exchanging a predetermined control signal or character between the electronic device and the external device are usually used to notify whether the external device is plugged into the electronic device. However, not all devices have the function of actively exchanging the predetermined signal or character initially. Further, when the system is closed or enters into the power saving mode, the method that confirms whether the external device is connected to the electronic device via telecommunication transmission is inapplicable.

A conventional plug detecting device is disclosed, and it detects whether an external device is connected via a metal piece disposed at a circuit board and electrically connected to a signal processing unit. Since the metal piece should be very close to the connector of the plug detecting device to allow the plug of the plugged external device to contact the metal piece further to change the potential of the metal piece, the circuit board provided with the metal piece also should be disposed closely to the opening of the connector. In this way, the position of disposing the circuit board goes against the design of stacking a plurality of connectors. The design of directly disposing the metal piece at the circuit board is possible to make the connector and the metal piece have bad contact.

BRIEF SUMMARY OF THE INVENTION

The invention provides a connector module used to a detecting device for connecting an electronic device having a plug. The connector module includes a body and a detecting member. The body has a connecting port and a connecting sidewall. The detecting member is disposed on the connecting sidewall and electrically connected to a power terminal and a signal processing unit of the detecting device, and it has a potential. When the plug is connected to the connecting port, the plug contacts the detecting member to change the potential, and the signal processing unit can detect the change of the potential to confirm that the electronic device is connected to the connector module.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in FIG. 1, a detecting device 100 of an embodiment of the invention is used to detect the connection of an electronic device. The electronic device has a plug having a metal covering and capable of being connected to the detecting device 100.

The detecting device 100 includes a connector module 110 and a circuit board 130, and the connector module 110 includes a body 111 and a detecting member 113. The circuit board 130 is disposed in the body 111 and has a power terminal 131 and a signal processing unit 133. FIG. 4 is a schematic diagram showing the connection relationship between the connector module and the circuit board of the embodiment of the invention. As shown in FIG. 4, the circuit board 130 is electrically connected to the connector module 110, and it provides electricity for the connector module 110 via the power terminal 131.

The body 111 has an opening N, a connecting port 111C and a plurality of connecting sidewalls 111S. The connecting port 111C is disposed in the opening N, and the connecting sidewalls 111S are formed inside the opening N and around the connecting port 111C.

As shown in FIG. 2, in another embodiment of the invention, the connector module 110 of a detecting device 100′ includes a body 111 and a detecting member 113. The body 111 has a connecting port 111C′ and four connecting sidewalls 111S′. The connecting port 111C′ protrudes from the body 111, and the connecting sidewalls 111S′ are formed at the outer surface of the connecting port 111C′ and around the connecting port 111C′.

As shown in FIG. 1 and FIG. 2, the detecting member 113 may be a metal piece or a metal pin and is disposed on one of the connecting sidewalls 111S and 111S′. The detecting member 113 is insulated from the connecting sidewalls 111S and 111S′. The detecting member 113 is electrically connected to the power terminal 131 and the signal processing unit 133 and has a potential. The detecting member 113 is not limited to the above metal piece or the metal pin, and it can be a metal member with any form. The detecting member 113 is protrudently disposed on the connecting sidewalls 111S and 111S′.

When the plug of the electronic device is connected to the connecting port 111C, the metal portion of the plug contacts the detecting member 113 to change the potential of the detecting member 113. When the signal processing unit 133 detects the change of the potential, it can confirm that the electronic device is connected to the connector module 110.

The detecting devices 100 and 100′ of the embodiments of the invention can be used to detect the connection of any type of plug, such as 1394, VGA, ESATA, USB, DVI, HDMI and COM. Only if the plug has a metal covering, the potential of the detecting member 113 is changed when the plug contacts the detecting member 113. In the embodiments of the invention, the detecting member 113 is directly disposed on the connecting sidewalls 111S and 111S′, and therefore, connector modules 110 of a detecting member 100″ can be stacked (as shown in FIG. 3) to save space. Furthermore, no matter the electronic device has a male connector or a female connector, it can be detected via the detecting device 100 or the detecting device 100′ of the embodiment of the invention (as shown in FIG. 1 and FIG. 2).

Although the present invention has been described in considerable detail with reference to certain preferred embodiments thereof, the disclosure is not for limiting the scope of the invention. Persons having ordinary skill in the art may make various modifications and changes without departing from the scope and spirit of the invention. Therefore, the scope of the appended claims should not be limited to the description of the preferred embodiments described above.
