Description

A socket with switch protection

technical field

The utility model relates to a socket, in particular to a socket with switch protection.

Background technique

Power sockets are widely used in industrial appliances and household appliances. At present, the sockets on the market are mainly divided into ordinary sockets, sockets with fuses, sockets with switches, and sockets with switch fuses. The following uses AC sockets as an example, as follows:

1. Ordinary socket

The plug mating end of the ordinary socket has three terminals, and the reverse side has three terminals or welding wire ends. The three terminals on the reverse side are integrated with the front three terminals, or connected by two parts or multiple parts.

2. With fuse socket

Compared with the ordinary socket, the socket with fuse is connected with a fuse in series on the plugged live pin.

3. Switch socket with protection

Compared with the ordinary socket, the switch socket with protection is connected with a switch in series on the plugged live pin.

4. With switch fuse socket

Compared with the ordinary socket, the fuse socket with switch connects a switch and fuse in series on the live wire pin inserted.

Although the above sockets with fuse protection, sockets with switch protection and fuse sockets with switch have added some protection functions compared with ordinary sockets, they have not considered the problem of loose and improper fit between the plug and socket. A fuse or a switch or a switch plus a fuse are connected in series at the feet. Adding a fuse can only play a role in overload or short circuit. Adding a switch just makes the socket electrified, and cannot solve the problem of loose or inappropriate fit between the plug and the socket.

Because in the actual use process, many times when people insert the plug, some people often do not pay attention to not inserting the plug to the end, and the contact surface between the plug and the socket is not tight or loose, so that the connection between the plug and the socket is easy to catch fire or heat. Letting it go on can lead to burning out electrical appliances or equipment. In fact, there are many accidents in the market due to this reason.

One end of extension spring 80 is connected with movable contact piece 90, and the other end is connected with movable support 60, and forms a link mechanism; One end of movable contact piece 90 is connected with fixed support 50, and the other end is provided with movable contact 91; During work, movable support 60 drives the extension spring 80 to work, and the extension spring 80 drives the movable contact 90 to rotate, so that the movable contact 91 on the movable contact 90 contacts the static contact 41 on the contact pin 40 .

In the utility model, the static contact 41 is fixed on the contact pin 40 by riveting or electric welding, and the movable contact 91 is also fixed on the movable contact piece 90 by riveting or electric welding.

Referring to Fig. 5 and Fig. 6, when the power plug 100 is inserted into the socket from the outside, it must be inserted to a certain position before the push rod can be touched, and then inserted inward for a certain distance to make the switch part conduct, so that the socket can provide power to the electrical appliances. Or equipment power supply; when the plug is not inserted to the required distance, the switch will not work, which effectively prevents the plug from not being inserted in place, resulting in loosening of the plug and socket, ignition or heat, which can lead to burning electrical appliances or equipment. The plug mentioned here is inserted at a certain distance. The safe distance of a certain distance as shown in Figure 5 is generally 1-3mm. Since the size of plugs and sockets produced by each company will have certain differences, this distance can be increased or decreased. , which will not be described here.

The working principle of the utility model is as follows:

Example 1

When the external plug 100 is inserted into the socket body 10 from the outside, when it is inserted to a certain distance, the plug 100 starts to touch the push lever 70 of the switch component, and as the plug 100 is continuously stretched in, the push lever 70 is also continuously pushed into the switch component. Move, after moving to a certain distance, one end of the push rod 70 located in the switch base 20 contacts with the movable bracket 60, and drives the movable bracket 60 to move, and the end connected with the fixed bracket 50 is used to fix the slot on the bracket 50 Rotate as a fulcrum, since the movable bracket 60 is also connected with a tension spring 80, the tension spring 80 is connected with the movable bracket 60 and the movable contact piece 90; when the push rod 70 is pressed down for a certain distance, the push rod 70 drives the movable bracket 60 also rotates to the corresponding position, movable bracket 60 drives extension spring 80 to work, and extension spring 80 pulls movable contact piece 90, and movable contact piece 90 uses fixed bracket 50 as the fulcrum to carry out rapid flipping, and after moving contact piece 90 flips over, the moving contact piece The movable contact 91 on the 90 is just pasted on the static contact 41, because the static contact 41 is fixed on the contact pin 40, and because the fixed support 50 is connected with the live wire sheet 13, the movable contact 90 and the fixed support 50 connection, now the contact pin 40 and live wire piece 13 are indirectly conducted, and the contact pin 40 is output as the live wire; when this position is reached, the live wire piece 13, the ground piece 12 and the neutral wire piece 11 on the socket body 10 are three conductive parts. Completely cooperate with the corresponding metal parts of the external plug to form a connector. When the external plug moves to the bottom, the push rod is also pressed to a certain position. Because the movable bracket, the fixed bracket, the tension spring 80 and the movable contact piece 90 are formed quickly With the jumping link mechanism, the distance between the switch contacts does not change with the insertion distance of the plug. Only when it is inserted into a certain position, it switches instantaneously, so when it is pressed down again, it does not affect the movable contact 91 and the static contact 41. The contact between them, the stroke of pressing down is just over-stroke.

Furthermore, as long as the socket adopts the switch component of the present application and the socket with the switch component of the present application falls within the scope of protection of the present application.
