Description

a safety socket

technical field

The utility model relates to the field of power supply equipment, in particular to a safety socket.

Background technique

Traditional home appliance sockets are divided into two types with protective doors and non-protective doors. This type of socket is far from enough to protect the safety of electricity. The failure of the protective door and some incorrect use are prone to accidents. For example, electric shock accidents caused by children and young children inserting metal or fingers into the socket out of curiosity. Therefore, traditional home appliance sockets cannot completely guarantee the safety and rationality of using electricity for minors, especially children.

The existing safety socket is a socket plus a protective door, and the socket is mechanically protected from electric shock. But once this kind of socket protection door is damaged, the anti-shock function will fail, especially for the smaller metal wires of diameter, it is easy to insert when the protection door is not opened, and electric shock accidents will also occur; It is used as a toy, so the mechanical protective door not only cannot prevent electric shock, but may also induce electric shock accidents.

Utility model content

Aiming at the shortcomings of the background technology, the utility model provides a safety socket. When a plug is inserted, the circuit is connected, and when a non-plug is inserted, the circuit is disconnected, so as to prevent electric shock accidents caused by people's mistakes, especially children's mistakes, and play a role in safety. Effective security protection.

In order to achieve the above object, the technical solution of the utility model is as follows:

A safety socket, comprising a socket body and a socket cover on the socket cover, jacks are provided on the socket cover corresponding to the socket body, and it is characterized in that: there are slide bar holes between the sockets, and the socket body is provided with There is a slide bar, and the slide bar passes through the slide bar hole and slides in the slide rail provided on the socket body; the bottom of each terminal of the socket body is connected with a fixed contact, and a movable contact corresponding to the fixed contact is arranged under the slide rail. point, the upper end of the movable contact is connected with an elastic device, and the sliding rod presses down on the elastic device so that each movable contact moves to contact with the corresponding fixed contact.

Preferably, the sliding rod is made of plastic.

Preferably, the elastic device is a copper shrapnel.

Preferably, the slide bar is arranged at the center of the socket.

Preferably, the shape of the upper part of the slider passing through the hole of the slider is a cuboid structure, which is convenient for the plug to press the slider; the middle part is a semicircular structure protruding from both sides, which reduces the resistance of the slider sliding on the slider; the bottom and The contact part of the elastic device is an inverted trapezoidal structure, and the trapezoidal inclined surface is in contact with the elastic device, which can reduce the resistance during extrusion friction and make the sliding smoother.

Beneficial effects of the utility model: the utility model is simple in structure and novel in design. The slide bar is set at the center of the jack, and the contacts can only be connected when the plug is inserted and the slide bar is pressed in. When the conductor is inserted into the socket, the metal contacts will not touch and the circuit will not work, thereby providing an effective safety guarantee.

Among them: 1. Slide bar, 2. Slide rail, 3. Movable contact, 4. Fixed contact, 5 Jack, 6. Shrapnel.

detailed description

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 and 2, a safety socket includes a two-headed and three-headed universal socket body and a socket cover on it. The socket cover is provided with a jack 5 corresponding to the socket body, three jacks and two A slide bar hole is provided in the middle of the socket, and the slide bar 1 passes through the slide bar hole to slide in the slide rail 2 provided on the socket body. The bottom of each terminal of the socket body is connected with a fixed contact 4, and a movable contact 3 corresponding to the fixed contact 4 is provided under the slide rail 2, and a copper shrapnel 6 is connected to the upper end of the movable contact 3. The sliding bar 1 moves each movable contact 3 to make contact with the corresponding fixed contact 4 by pressing down the copper elastic piece 6 .

As shown in Figure 1, the shape of the upper part of the slider 1 passing through the hole of the slider is a rectangular parallelepiped structure, which is convenient for the plug to press the slider 1; The resistance; the contact part between the bottom and the shrapnel 6 is an inverted trapezoidal structure, and the trapezoidal slope is in contact with the shrapnel 6, which can reduce the resistance during extrusion friction and make the sliding smoother.

Specific embodiments: when the electrical plug is inserted into the jack 5, the slide bar 1 is pressed downward under the action of the plug, the movable contact 3 contacts the fixed contact 4, and the power is turned on. When the plug is pulled out, the movable contact 3 is separated from the fixed contact 4 under the action of the shrapnel 6, and the power supply is disconnected. When objects such as metal wires are inserted or children insert their fingers into the jack due to curiosity, the slide bar 1 will not be squeezed, so the power supply is in a disconnected state, which has a safety protection effect.
