The utility model is realized with following technical scheme：A kind of grounding switch ground detection device, including insulating bar,
The lower end of the insulating bar is provided with end cap, and the interior of the insulating bar is provided with ground wire, and the lower end of the ground wire is connected with earth clip,
The upper end of the ground wire is connected with the ground detection device for being arranged on insulating bar upper end, and the upper end of the ground detection device is set
There is metal contact flat spring, grounded inspection circuit is provided with the ground detection device.
It is further：The both ends of the grounded inspection circuit of the ground detection device are connected on ground wire respectively and metal connects
Touch shell fragment on, the grounded inspection circuit by ground wire to metal contact flat spring be sequentially connected in series power supply, triode, buzzer and
Light emitting diode, resistance is equipped between power supply and triode and between light emitting diode and metal contact flat spring.
The metal contact flat spring is the sheet metal of installation camber.
The utility model has advantages below：Novel grounded disconnecting link ground detection device of the present utility model passes through ground wire
The connection of the device and grounded screen can be conveniently realized, provides earth point for detection means, while ground detection device can connect
Acoustical signal and optical signal are provided in the case that ground is good, easy to operate, to grounding switch, whether good earth detects, and then
Ensure maintainer's personal safety.

Embodiment
A kind of grounding switch ground detection device as shown in Figure 1 to Figure 2, including insulating bar 4, under the insulating bar 4
End is provided with end cap 6, and the interior of the insulating bar 4 is provided with ground wire 3, and the lower end of the ground wire 3 is connected with earth clip 5, the ground connection
The upper end of line 3 is connected with the ground detection device 2 for being arranged on the upper end of insulating bar 4, and the upper end of the ground detection device 2 is provided with gold
Belong to contact flat spring 1, grounded inspection circuit is provided with the ground detection device 2.Grounding switch earthing detection of the present utility model
Device is provided with insulating bar, and is provided with end cap in lower end, facilitates folding insulating bar, and the inside of insulating bar is provided with ground wire, ground wire
Lower end is connected with earth clip, after end cap is opened, can be connected by earth clip with grounded screen；The upper end of insulating bar is provided with ground connection
Detection means, while the other end being grounded links together with ground detection device, the upper end of ground detection device is provided with gold
Belong to contact flat spring, grounded inspection circuit is additionally provided with inside ground detection device, whether detection grounding switch is just true to be grounded when needing
When, earth clip is connected in grounded screen, metal contact flat spring contacts with grounding switch, if grounding switch ground connection is effective, that
The grounded screen and grounding switch that grounding switch ground detection device is connected with both ends just form a closed circuit, earthing detection
Circuit forms closed-loop path, and grounded inspection circuit sends signal, and instruction ground connection is effective, conversely then invalid.
A kind of grounding switch ground detection device as shown in Figure 1 to Figure 2, the earthing detection of the ground detection device 2
The both ends of circuit are connected on ground wire 3 and metal contact flat spring 1 respectively, and the grounded inspection circuit is connect by ground wire 3 to metal
Touch shell fragment 1 and be sequentially connected in series power supply, triode, buzzer and light emitting diode, between power supply and triode and light-emitting diodes
Resistance is equipped between pipe and metal contact flat spring 1.Grounded inspection circuit of the present utility model is mainly by power supply, triode, honeybee
Ring device and light emitting diode composition, and is provided with resistance in relevant position, detected in figure A the and B ends of circuit respectively be grounded and
Metal contact flat spring links together, when ground wire and metal contact flat spring are respectively connected to grounded screen and the grounding switch closed
When, it can detect whether grounding switch is really grounded by the break-make of whole circuit, and send out by light emitting diode and buzzer
Go out signal, to prompt ground connection whether effective.
A kind of grounding switch ground detection device as shown in Figure 1 to Figure 2, the metal contact flat spring 1 are to be mounted to arc
The sheet metal of shape.The lower end of metal contact flat spring of the present utility model is fixed on the top of ground detection device, metal contact
Shell fragment bearing bend camber, when contact surface is arc, can preferably contact, when metal contact flat spring touch it is flat
During face, because metal contact flat spring is sheet metal, somewhat firmly can be in close contact with plane, therefore metal contact flat spring and
Cambered surface and plane can be preferably bonded.
