Specific embodiment

Also referring to Fig. 1 and Fig. 2, it illustrates socket 1 provided by the preferred embodiment of the utility model.The row It inserts 1 and include but are not limited to shell 10, detection unit 20, prompt unit 30, electric wire 40 and circuit board 50.In present embodiment In, the detection unit 20, prompt unit 30, electric wire 40 and circuit board 50 are installed in the shell 10, the prompt unit 30 is also exposed from the shell 10 with the electric wire 40.

In the present embodiment, the detection unit 20 is electrically connected with prompt unit 30, and detection unit 20 is installed in It is electrically connected on the circuit board 50 and with the circuit board 50, one end of the electric wire 40 electrically connects with the circuit board 50 It connects, the other end is electrically connected with electric wire.

The detection unit 20 is used to detect whether the socket 1 is grounded when the socket 1 is powered, the prompt unit 30 for exporting standby signal when the detection unit 20 detects that the socket 1 is unearthed, to prompt user couple in time The socket 1 is repaired or replaced, to ensure Electrical Safety.

Specifically, the socket 1 further includes an at least three-way jack 60.The detection unit 20 is used in the socket 1 Detect whether the three-way jack 60 is grounded when energization, the prompt unit 30 be used for when the detection unit 20 detect it is described When three-way jack 60 is unearthed, the standby signal is exported.

In the present embodiment, the three-way jack 60 includes a ground terminal 61, and the detection unit 20 is ground resistance Test device.The detection unit 20 is used to measure the ground resistance of the ground terminal 61 of the three-way jack 60, and described in judgement Whether ground resistance is less than or equal to preset value, when determining that the ground resistance is greater than the preset value, determines three line Jack 60 is unearthed.In the present embodiment, the preset value is 4 ohm.It is understood that in other embodiments, The preset value can also be set as other suitable numerical value according to user demand.
