Description

Detection device and its connector module

technical field

The present invention relates to a connector module, in particular to a connector module with detection function for detecting the connection of an electronic device.

Background technique

The connectors of most electronic devices do not have the function of detection. When an external device is plugged in, the communication protocol between the electronic device and the external device is usually used, or the program that can exchange preset control signals or characters between them to inform whether there is an external device connected to the electronic device. However, not all devices have a mechanism for actively initiating the exchange of preset signals or characters. Furthermore, when the system is turned off or enters power saving mode, the above-mentioned method needs to be transmitted by means of telecommunication to confirm whether an external device is plugged in. does not apply.

It is known and disclosed a plug detection device, which utilizes a metal shrapnel disposed on a circuit board to be electrically connected to a signal processing unit to detect whether an external device is plugged in. Since the metal shrapnel must be very close to the connecting socket of the plug detection device, the connecting plug of the inserted external device can contact the metal shrapnel, thereby changing the voltage level of the metal shrapnel. Therefore, the circuit board with the metal shrapnel must also be set in It is very close to the opening of the connection socket, so that the installation position of the circuit board will hinder the design of multiple stacked connection sockets. In addition, the design of the metal shrapnel directly arranged on the circuit board may also cause poor contact between the connection plug and the metal shrapnel.

Detailed ways

Referring to FIG. 1 , the detection device 100 of the present invention is used to detect the connection of an electronic device, wherein the electronic device is connected to the detection device 100 of the present invention through a joint with metal coating.

The detection device 100 includes a connector module 110 and a circuit board 130, the connector module 110 includes a body 111 and a detection part 113, wherein the circuit board 130 is arranged in the body 111, and has a power supply terminal 131 and a signal processing unit 133, please refer to FIG. 4. FIG. 4 is a diagram of the connection relationship between the connector module and the circuit board of the present invention. It can be seen from the figure that the circuit board 130 is electrically connected to the connector module 110, and the power supply terminal 131 is used to provide electricity.

The body 111 has a groove N, a connecting end 111C and a plurality of connecting sidewalls 111S, the connecting end 111C is disposed in the groove N, and the connecting sidewall 111S is also formed on the inner wall of the groove N in a manner surrounding the connecting end 111C .

2, in another embodiment of the present invention, the connector module 110 of the detection device 100' includes a body 111 and a detection part 113, the body 111 has a connecting end 111C' and four connecting side walls 111S', The connection end 111C' protrudes from the body 111, and the connection sidewall 111S' is also formed on the outer edge of the connection end 111C' in a manner to surround the connection end 111C.

Referring to Figure 1 and Figure 2 at the same time, the detection part 113 can be a metal shrapnel or a metal pin, which is arranged on one of the connection side walls 111S, 111S', and is insulated from the connection side walls 111S, 111S', and detects The component 113 is electrically connected to the power terminal 131 and the signal processing unit 133 respectively, and has a voltage level.
