Description

A switch that automatically disconnects in case of power failure

technical field

The invention relates to a switch, in particular to a switch that is automatically disconnected in case of power failure.

Background technique

Wall switch is a product that people use every day in their daily life. Whether it is a family, a work unit or a school, etc., any place that needs electricity is inseparable from the switch. The development of the switch in these years is also very rapid. From From the initial pull switch to more and more high-end smart switches, the development of switches has brought more and more convenience to people's lives. Although the smart switch is the most convenient switch in life, it is expensive and cannot be popularized, especially the large number of switches used in most household decorations, which is unacceptable for expensive consumption, and the technology is immature. Not stable enough. Therefore, the switch that is most widely used at present and can be recognized by consumers is a rocker switch. The types of rocker switches can meet people's needs not only in function but also in appearance. A common problem is that when there is a power outage due to special reasons, people need to manually press the button to turn off the power. Otherwise, if there is a sudden power outage at night, a sudden call after falling asleep will affect sleep, and if the light is still on when the call comes in during the day, there is no power at this time. When people are at home, energy is wasted. Similarly, most companies need electricity during the day. If the button is not pressed after a power outage, the light may be on all night when the power comes in at night, which is a serious waste of energy.

Contents of the invention

The purpose of the present invention is to provide a switch that automatically disconnects when power failure occurs, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the present invention provides the following technical solutions:

A switch for automatic disconnection in case of power failure, including an installation box, a panel and a switch cover, a fixed box is arranged inside the installation box, and the fixed box is composed of two U-shaped boxes, and a distance is left between the two U-shaped boxes for easy installation Conductive copper sheet 1 and copper sheet 2, the end of the copper sheet 1 is provided with terminal 1, and the other end is fixed to the coil; the end of the copper sheet 2 is provided with terminal 2, the other end is fixed with a spring, and the other end of the spring is fixed One end of the iron sheet arranged at the bottom of the rocker, the other end of the iron sheet is not fixed to the coil; the upper part of the fixed box is provided with a rocker fixing hole, which is convenient for the shaft provided on the rocker to pass through and connect, and the rocker is then The two ends of the rocker can be rocked up and down with the shaft as the fulcrum. A switch cover is arranged above the rocker, and a fixed column is arranged on the bottom surface of the switch cover. The fixed column is fixed in the cover fixing holes provided at both ends of the rocker; the panel is above the installation box, There is a square hole in the middle of the panel, which is convenient for installing the switch cover.

Further, the spring is a tension spring.

Further, four corners of the bottom of the installation box are provided with installation holes.

Compared with prior art, the beneficial effect of the present invention is:

The invention has reasonable structure and simple principle. When the circuit is turned on, the coil and the iron sheet are attracted by the principle of the electromagnet. After the power is turned off, the suction force is lost and the spring pulls the seesaw, and the switch is automatically disconnected. The invention is convenient to use, low in cost, safe and reliable. , can be widely applied.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figure 1-2, the preferred embodiment of the present invention is as follows:

A switch for automatic disconnection in case of power failure, comprising an installation box 1, a panel 2 and a switch cover 3, the installation box 1 is provided with a fixed box 5 inside, and the fixed box 5 is composed of two U-shaped boxes, two U-shaped boxes There is spacing in the middle to facilitate the installation of conductive copper sheet one 61 and copper sheet two 62, the end of the copper sheet one 61 is provided with a terminal one 71, and the other end is fixed to the coil 9, and the terminal one 71 is connected to the wire during installation; The end of copper sheet 2 62 is provided with connecting terminal 2 72, and connecting terminal 2 72 is connected with wire during installation, and the other end of copper sheet 62 is fixed spring 8, and the other end of spring 8 is fixed on the iron sheet 10 that rocker 11 bottom is provided with. One end of the iron sheet 10 is not fixed to the coil 9; the upper part of the fixed box 5 is provided with a rocker fixing hole, which is convenient for the shaft 13 provided on the rocker 11 to pass through the connection, and the rocker 11 can be used for the shaft 13 is the two ends of the fulcrum rocking up and down, the switch cover 3 is arranged above the rocker 11, the bottom surface of the switch cover 3 is provided with a fixed column 4, and the fixed column 4 is fixed in the cover plate fixing holes provided at the two ends of the rocker 11; the panel 2 On the top of the installation box 1, there is a square hole in the middle of the panel 2, which is convenient for installing the switch cover 3.

Further, the spring 8 is a tension spring.

Further, the four corners of the bottom of the installation box 1 are provided with installation holes.

Working principle of the present invention is:

When the user manually presses the switch cover 3, the coil 9 is in contact with the iron sheet 10, and the circuit will be turned on. After the power is turned on, the coil 9 will be magnetic, so as to be attracted to the iron sheet 10 at the bottom of the seesaw 11. At this time, the spring 8 It is in a stretched state; if the power is cut off, the coil 9 will lose its magnetism and cannot absorb the iron sheet 10, and the spring 8 will pull the rocker 11, so that the coil 9 and the iron sheet 10 are completely separated, even if the incoming call switch is still in the off state , greatly reducing energy waste.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
