Abstract

The utility model provides a safety power-supply switching device which relates to the field of the electricity. The utility model is characterized in that the outer margin of the base (5) of a socket box (2) is provided with a step (8), and a plug box (1) is matched with the socket box (2), and is sheathed on the step (8) of the base (5) of the socket box (2). Meanwhile, the inner plug (3) of the plug box (1) is inserted into a socket reed (4) in the socket box (2), and the power supply is connected. When the plug box (1) is pulled out, the power-supply switching device is powered off. The utility model overcomes the unsafe disadvantage of the existing power switch whose plug is exposed. The utility model has the advantages of reasonable design, simple structure, and safety.

Description

Safety power switching device

The utility model relates to the essential electronic element field of electricity, relates to a kind of safety power switch device particularly.

General traditional attaching plug box, the version that socket box matches of adopting of existing power supply switch, power connection in the reed of plug insertion socket box, the power supply that pulls the plug out of the socket from socket box promptly is cut off.Though it has simple in structure, also there is following shortcoming in easy to operate advantage, the one, plug is inserted when not in place, plug is charged be exposed to outside, when staff touches, easily get an electric shock, be absolutely unsafe, especially children use its mains switch electric shock phenomenon to happen occasionally; The 2nd, the interior electrode copper sheet of socket box contacts not firm with plug when loosening, occur the switch-on and-off phenomenon easily, and its service behaviour is not good enough etc.

The purpose of this utility model is that a kind of improved safety power switch device will be provided, it can guarantee effectively people use in safety, its excellent working performance is reliable.

The purpose of this utility model is to realize by the improvement design to its plug box, socket box.Its major technique feature is the screw that an end is provided with two hold-down screws 6 on the center line of the base 5 in socket box 2, is respectively equipped with Die for Reeds of Connector Jack 4 on its center line both sides relative position; The other end is provided with a Die for Reeds of Connector Jack 4, and power line (7) is connected with Die for Reeds of Connector Jack 4 respectively from an end, and the outer rim of the base 5 of socket box 2 is provided with a step (8); Plug box 1 matches with socket box 2, and is sleeved on the outer rim step 8 of its base 5, be provided with in the plug box 1 with socket box 2 in the plug 3 of Die for Reeds of Connector Jack 4 corresponding cooperations, power line 7 is from the other end attachment plug 3 respectively of plug box 1.

Its technical characterictic is a plug box 1, and socket box 2 usefulness insulating material are made.

The utility model is because only need be to its plug box 1, and the box body of socket box 2 improves design, so it is simple in structure; Because plug box 1 is sleeved on the socket box 2, outside its plug can not be exposed at all, and be provided with ground wire within it simultaneously, its appearance similar, so it has safe and reliable performance, the phenomenon of stopping to get an electric shock takes place, and operation does not have any specific (special) requirements, even children, blind person, it is reliable also to be perfectly safe.In addition since plug box 1 closely cooperate with socket box 2, so do not misplace excellent working performance during plug.

Concrete structure of the present utility model is provided by following enforcement and accompanying drawing thereof.

Fig. 1 is structural front view of the present utility model (A-A);

Fig. 2 is the B-B view of Fig. 1;

Fig. 3 is Fig. 1 C-C view.

Describe this device details and working condition in detail below in conjunction with accompanying drawing 1,2,3.

This device comprises that a plug box 1(is shown in Figure 2), a socket box 2(is shown in Figure 3), plug box 1 is sleeved on the outer rim step 8 of base 5 of socket box 2 (shown in Figure 1), and socket box body and function screw 6 is fixed on its base 5.Among Fig. 1, mains switch is in on-state, plug box 1, and socket box 2 is connected situation with electrical equipment or power supply, does not draw among the figure.During work, plug box 1 is sleeved on the outer rim step 8 of the base 5 on the socket box 2, plug 3 also inserts in the Die for Reeds of Connector Jack 4 simultaneously, and is closely together.) shown in Figure 1), the mains switch energized, with plug box 1 when socket box 2 unplugs, the mains switch outage, easy to operate.It is reasonable in design, and is simple in structure, safe and reliable, especially is suitable for children, blind person's use, should popularize.

Claims (2)

1, a kind of safety power switch device that contains plug box, socket box, plug and socket reed, it is characterized in that an end on the center line of the base (5) in socket box (2) is provided with the screw of two hold-down screws (6), is respectively equipped with Die for Reeds of Connector Jack (4) on the corresponding position, its both sides; The other end is provided with a Die for Reeds of Connector Jack (4), and power line (7) is connected with Die for Reeds of Connector Jack (4) respectively from an end, and the outer rim of the base (5) of socket box (2) is provided with a step (8); Plug box (1) matches with socket box (2), and be sleeved on the outer rim step (8) of its base (5), be provided with in the plug box (1) with socket box (2) in the plug (3) of Die for Reeds of Connector Jack (4) relative engagement, power line (7) is from the other end attachment plug (3) respectively of plug box (1).
