Abstract
Disclosed in the utility model is a single control-to-dual control conversion junction box with signal detection. The junction box comprises a box body. A first single-pole double-throw relay and a second single-pole double-throw relay are arranged in the box body; a normally-closed contact of the first single-pole double-throw relay is connected with a normally open contact of the second single-pole double-throw relay; a normally open contact of the first single-pole double-throw relay is connected with a normally-closed contact of the second single-pole double-throw relay; a moving contact of the first single-pole double-throw relay and a moving contact of the second single-pole double-throw relay and lighting equipment are connected in series to a commercial power supply circuit; a coil of the first single-pole double-throw relay is connected with a control source by a first switch; a coil of the second single-pole double-throw relay is connected with the control source by a second switch. According to the utility model, combination of the two single-pole double-throw relays is utilized to control connection and disconnection of a home illuminating line, thereby realizing double-control illuminating line; weak currents can be used to control the home lighting equipment, so that security and convenience are realized. Moreover, the junction box has advantages of simple structure, easiness of realization and high practicability.
Description
Technical field
The utility model relates to a kind of terminal box, and the single control that relates in particular to a kind of band signal detection turns the dual control terminal box.
Background technology
At present, the illuminating line in the resident family mostly is the single control illuminating line.Along with the safety of residents electricity consumption require growing, use light current control home lighting equipment, and realize that the single control illuminating line turns the demand that the dual control illuminating line has become many residents.
The utility model content
The single control that the purpose of this utility model provides a kind of band signal detection turns the dual control terminal box, can transfer the home lighting circuit to the dual control illuminating line by the single control illuminating line, utilizes light current control home lighting equipment, safe ready.
The utility model adopts following technical proposals:
The single control that a kind of band signal detects turns the dual control terminal box, comprise box body, be provided with the first single-pole double throw relay and the second single-pole double throw relay in the box body, the normally-closed contact of the first single-pole double throw relay connects the normally opened contact of the second single-pole double throw relay, the normally opened contact of the first single-pole double throw relay connects the normally-closed contact of the second single-pole double throw relay, the first single-pole double throw relay moving contact, the second single-pole double throw relay moving contact and lighting apparatus are connected on the mains-supplied circuit, the first single-pole double throw relay coil KM1 connects the control power supply by the first switch, and the second single-pole double throw relay coil KM2 connects the control power supply by second switch.
Described control supply voltage is 5V.
The utility model utilizes conducting and the disconnection of the combination control home lighting circuit of two single-pole double throw relays, thereby realizes the dual control illuminating line, can utilize light current control home lighting equipment, safe ready, the utility model is simple in structure, is easy to realize, and is practical.
Description of drawings
Fig. 1 is theory diagram of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises box body, be provided with the first single-pole double throw relay and the second single-pole double throw relay in the box body, the normally-closed contact K2 of the first single-pole double throw relay connects the normally opened contact K5 of the second single-pole double throw relay, the normally opened contact K3 of the first single-pole double throw relay connects the normally-closed contact K6 of the second single-pole double throw relay, the first single-pole double throw relay moving contact K1, the second single-pole double throw relay moving contact K4 and lighting apparatus are connected on the power supply circuits, the first single-pole double throw relay coil KM1 connects the control power supply by the first K switch 7, and the second single-pole double throw relay coil KM2 connects the control power supply by second switch K8.
In the present embodiment, the control supply voltage is 5V.The utility model in use, when not pressing again any one switch, not conducting of illuminating line, lighting apparatus is not worked.When the user wants to open lighting apparatus, only need press the first K switch 7 or second switch K8.
When the user wants to open lighting apparatus, when the first K switch 7 is pressed in selection, the first single-pole double throw relay coil KM1 energising, the first single-pole double throw relay moving contact K1 and normally opened contact K3 conducting, because the normally opened contact K3 of the first single-pole double throw relay connects the normally-closed contact K6 of the second single-pole double throw relay, illuminating line conducting this moment, lighting apparatus work.When the user wants to close the lighting apparatus of having opened, only need press second switch K8, the second single-pole double throw relay coil KM2 energising this moment, the second single-pole double throw relay moving contact K4 and normally opened contact K5 conducting, and the second single-pole double throw relay moving contact K4 and normally-closed contact K6 disconnect, illuminating line disconnects, and can close lighting apparatus.
When the user wants to open lighting apparatus, when second switch K8 is pressed in selection, the second single-pole double throw relay coil KM2 energising, the second single-pole double throw relay moving contact K4 and normally opened contact K5 conducting, because the normally-closed contact K2 of the first single-pole double throw relay connects the normally opened contact K5 of the second single-pole double throw relay, illuminating line conducting this moment, lighting apparatus work.When the user wants to close the lighting apparatus of having opened, only need press the first K switch 7, the first single-pole double throw relay coil KM1 energising this moment, the first single-pole double throw relay moving contact K1 and normally opened contact K3 conducting, and the first single-pole double throw relay moving contact K1 and normally-closed contact K2 disconnect, illuminating line disconnects, and can close lighting apparatus.
Because single-pole double throw relay and relay drive circuit belong to ripe prior art, do not repeat them here.
