Live line connection post in terminal board is touched in lid, false touch, electric shock injury accident will occur, therefore more serious potential safety hazard be present.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of motor terminals box auto-power-off device, the present apparatus
Existing motor terminals box is overcome in the defects of security protection, is connect when Electrician Operation personnel open powered motor by mistake
It can in time be powered off during line end lid, so as to avoid the generation of electric shock injury accident, prevent potential safety hazard.
In order to solve the above technical problems, motor terminals box auto-power-off device of the present invention is included provided with binding post
The switch trip loop of terminal box body, end cap and motor, in addition to voltage detection module, motor operating indicator lamp, motor
Stop indicator lamp and automatically power off limit switch, the input of the voltage detection module connects the wiring of the terminal box body
Post, output end connect the motor operating indicator lamp and motor and stop indicator lamp respectively, and the limit switch that automatically powers off carries
Normally-closed contact and located between the terminal box body and end cap, the normally-closed contact is serially connected with the switch trip loop
In.
Further, the limit switch that automatically powers off is two, and described two limit switches that automatically power off are respectively arranged on institute
The diagonal position of terminal box body is stated, the switch is serially connected with after described two normally-closed contact parallel connections for automatically powering off limit switch
In trip(ping) circuit.
Further, the motor operating indicator lamp is red led, and it is green indicating lamp that the motor, which stops indicator lamp,
The motor operating indicator lamp is glittering after the voltage detection module detects the wiring column voltage, and otherwise the motor stops
Indicator lamp is glittering.
Further, it is integral type structure that the voltage detection module, motor operating indicator lamp, motor, which stop indicator lamp, and
It is additional to be installed on the end cap.
Because motor terminals box auto-power-off device of the present invention employs above-mentioned technical proposal, i.e. the present apparatus includes being provided with
The switch trip loop of the terminal box body of binding post, end cap and motor, in addition to the operating instruction of voltage detection module, motor
Lamp, motor stop indicator lamp and automatically power off limit switch, the wiring of the input connection terminal box body of voltage detection module
Post, output end connect motor operating indicator lamp respectively and motor stops indicator lamp, automatically power off limit switch and carry normally-closed contact
And located between terminal box body and end cap, normally-closed contact is serially connected with switch trip loop.The present apparatus overcomes existing electricity
Motivation connecting terminal box, can when Electrician Operation personnel open powered motor wiring end cap by mistake in the defects of security protection
Power-off in time, so as to avoid the generation of electric shock injury accident, prevents potential safety hazard.
Brief description of the drawings
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the theory diagram of motor terminals box auto-power-off device of the present invention；
Fig. 2 is the schematic diagram of end cap in the present apparatus.
Embodiment
As depicted in figs. 1 and 2, motor terminals box auto-power-off device of the present invention includes being provided with binding post embodiment
The switch trip loop 2 of 11 terminal box body 1, end cap 12 and motor, in addition to the operating of voltage detection module 35, motor refer to
Show that lamp 31, motor stop indicator lamp 32 and automatically power off spacing limit switch 33, the input of the voltage detection module 35 connects
Connect the binding post 11 of the terminal box body 1, output end connects the motor operating indicator lamp 31 and motor and stops instruction respectively
Lamp 32, it is described to automatically power off limit switch 33 with normally-closed contact 34 and be located between the terminal box body 1 and end cap 12,
The normally-closed contact 34 is serially connected with the switch trip loop 2.
Preferably, the limit switch 33 that automatically powers off is two, and described two limit switches 33 that automatically power off are set respectively
Concatenated after the diagonal position of the terminal box body 1, described two parallel connections of normally-closed contact 34 for automatically powering off limit switch 33
In the switch trip loop 2.Use two to automatically power off limit switch to improve the reliability of present apparatus action, work as end cap
Depart from terminal box body to act up to a rare limit switch, so that it is guaranteed that motor terminals box powers off；For large-scale
Motor terminals box can also use multiple limit switches, avoid the present apparatus from failing.
Preferably, the motor operating indicator lamp 31 is red led, and it is that green refers to that the motor, which stops indicator lamp 32,
Show lamp, the motor operating indicator lamp 31 is glittering after the voltage detection module 35 detects the voltage of binding post 11, otherwise
It is glittering that the motor stops indicator lamp 32.Motor terminals box can intuitively be differentiated by red led and green indicating lamp
It is whether powered, play warning function.
Preferably, it is integral type knot that the voltage detection module 35, motor operating indicator lamp 31, motor, which stop indicator lamp 32,
Structure, it is additional to be installed on the end cap 12.
The present apparatus is gathered the voltage of binding post by voltage detection module, when binding post has voltage to show motor operation, connects
Line terminals tape electricity, and motor operating indicator lamp is lighted, conversely, then show motor stopping, connecting terminal box without electricity, and
Light motor and stop indicator lamp, so as to intuitively differentiate.When the powered electriferous state of connecting terminal box, end cap is such as dismantled, in terminal
When box body closes with end cap, the normally-closed contact for automatically powering off limit switch is off-state, when end cap departs from terminal box body
When, then the normally-closed contact for automatically powering off limit switch closes so that switch trip circuit behavior, switch trip, so as to cut off electricity
Motivation power supply, avoid Electrician Operation human contact's terminal board internal wiring terminal that electric shock accidents occurs, to ensure safety.
