Background technology
Distribution box be by the electrical wiring requirement be assembled in switchgear, measuring instrument, protection electrical equipment and auxiliary equipment in sealing or the semiclosed metal cabinet or the screen width of cloth on, constitute low-voltage distribution equipment.Can connect or the branch deenergizing by manual or automatic switch during normal the operation.Cut off circuit or warning by protection electrical equipment when fault or irregular operating.Borrow measuring instrument can show operating various parameter, also can adjust some electric parameter, point out or send signal to departing from normal operating conditions.Be usually used in each, join, in the electric substation.
In electric power system, for electric current distribution and the control of various partial powers, need in distribution box, carry out usually, it is equivalent to a small-sized power hub.Common, enter distribution box by many wires, after each Power entry module is partly realized the control of electric power and distributed, flow out distribution boxs by many wires again.Partly realize control and the distribution of electric power at described Power entry module; Generally the switch with distribution box interior distribution module is installed on the distribution chamber door, controls disconnection and the closure of the circuit of these Power entry modules at the distribution chamber door.
In distribution box, the break-make of some circuit can not cause the harm of especially severe, and for some extrahazardous circuit controling switch, what use on the distribution box also is identical switch, and these switches can not prevent well that mistake from causing closing of circuit by switch, be exactly live wire and zero line in the distribution box because the binding post of these switch inside directly connects, as long as the switch open circuit will be connected, can cause serious consequence just in case these switches open by mistake to open, so this can make the use of distribution box have potential safety hazard.
Therefore another application documents of the inventor disclose a kind of distribution box construction of switch, comprise base and lid, described lid is provided with switch, described base is provided with groove, be provided with internal thread in the described groove, be set with two conducting strips on the described internal thread, described conducting strip connects live wire and the zero line in the distribution box respectively, described lid is provided with external screw thread, described external screw thread and described screw-internal thread fit, described external screw thread is provided with two conductive contacts, and described two conductive contacts connect the two ends of described switch respectively.Base and lid are arranged to be threaded, and internal thread is provided with two conducting strips that are connected with circuit in the distribution box, external screw thread is provided with the conductive contact that links to each other with switch, make the tightening and unscrew and to realize switching on and off of circuit of screw thread between lid and the base, after disconnecting, switch lid outwards can be twisted, prevent that mistake is by causing the accident, when needs are opened switch, earlier lid is tightened and opened switch again, so just prevented effectively that mistake from causing the accident by switch, be specially adapted to dangerous circuit and use.But this construction of switch needs to tighten and unscrew lid in use, and the user is difficult in use judge that being screwed to what degree is that what degree of connection is to disconnect, and the application has well solved this problem.
Summary of the invention
The utility model is at the prior art deficiency, a kind of distribution box construction of switch that indicator light is arranged is provided, this kind construction of switch can prevent effectively that switch from opening by mistake and open, and improves switch fail safe in use, and has indicator light can make things convenient for the break-make of user's decision circuitry.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of distribution box construction of switch that indicator light is arranged, comprise base and lid, described lid is provided with switch, described base is provided with groove, be provided with internal thread in the described groove, be set with two conducting strips on the described internal thread, described conducting strip connects live wire and the zero line in the distribution box respectively, described lid is provided with external screw thread, described external screw thread and described screw-internal thread fit, described external screw thread is provided with two conductive contacts, and described two conductive contacts connect the two ends of described switch respectively, also is provided with indicator light on the described lid, described indicator light one end connects a conductive contact other end and is connected with power supply, and the described power supply other end connects the conducting strip of the conductive contact cooperation that is connected with indicator light.Base and lid are arranged to be threaded, and internal thread is provided with two conducting strips that are connected with circuit in the distribution box, external screw thread is provided with the conductive contact that links to each other with switch, make the tightening and unscrew and to realize switching on and off of circuit of screw thread between lid and the base, after switch disconnects, lid outwards can be twisted and not work up to indicator light, prevent that mistake is by causing the accident, when needs are opened switch, earlier lid is tightened to the bright switch of opening again of indicator light, so just prevented effectively that mistake from causing the accident by switch, being specially adapted to dangerous circuit uses, indicator light is set makes the user tighten when unscrewing lid can or not work decision circuitry whether to connect by the bright of indicator light, conveniently judge.
In the technique scheme, preferred, described two conductive contacts are arranged on described externally threaded centre, and the centre that described conducting strip is arranged on internal thread reaches with the lower part.Circuit was just connected when such design can guarantee to have only screw thread to be screwed to the end, had more improved security performance, prevented fortuitous event.
The utility model compared with prior art has following beneficial effect: the utility model makes and switching on and off the bright of indicator light and not working to indicate of circuit has made things convenient for the judgement of connecting and disconnecting of the circuit in this construction of switch.
