Description

Self-grounding wall socket

Technical Field

The utility model belongs to the electrical apparatus field provides a but wall socket of automatic ground connection suitable for china single phase alternating current system.

Background

1. One of the existing three-hole sockets is a ground wire and should be grounded according to the standard, but the installation requirement of the national standard on grounding is too high and single, so that the complex laying cost of the ground wire according to the national standard is too high during actual installation construction, and a plurality of wall sockets have no ground wires during actual construction.

2. Many electrical appliances use 3-hole plugs and wiring with ground wires according to national standard regulations, but superior wall sockets of main power supply ends are often not grounded, which causes great waste and potential safety hazards.

3. Although the existing wall socket has a grounding terminal, the existing wall socket is only prepared to be connected with a special grounding wire according to the national standard requirements, the existing wall socket is not hung and missed because of no special grounding wire, and the existing wall socket can be connected to a wall body nearby to realize a certain primary grounding function under the condition of no special grounding wire, but because the grounding resistance of the common wall body is not up to the standard, many electricians are unwilling to bear risks and afraid of troubles and do not carry out nearby grounding, so that waste and potential safety hazards are caused.

4. The existing wall socket comprises an open installation and a concealed installation which are not provided with devices convenient for nearby grounding.

5. The existing commercial power system mostly adopts a leakage protector to prevent the problem of electric leakage and electric shock, the practical effect is good, but the problem is that the absolute work is not guaranteed to be normal, once the danger occurs, the electric appliance or a socket can be fatal, and multiple protection means such as grounding and the like are also used, and the mode of grounding and leakage protection is also beneficial to finding the problem of electric leakage in advance, but not only plays a role when people get an electric shock.

The grounding device of the self-grounding wall socket is changed from being positioned at the side wall of the socket to being positioned at the back surface of the socket contacting with the wall body, and can be simultaneously positioned at a plurality of positions of the side wall or the back surface.

The self-grounding wall socket is provided with a spring clamping groove near a ground wire terminal, a spring which can be contacted with a wall body on the back of the socket can be arranged at the spring clamping groove, and the spring or a built-in conductor thereof is communicated with the ground wire terminal of the socket.

The self-grounding wall socket is characterized in that a grounding metal sheet is arranged on a rear shell of the socket, can be contacted with a wall body after being installed, and is internally communicated with a ground wire wiring terminal of the socket; the metal sheet can also be positioned on the inner core of the socket but can penetrate through the rear shell of the socket to contact with the wall.

The self-grounding wall socket is characterized in that the screw which is positioned on the side wall or the back of the socket and embedded into the wall body is communicated with the ground wire terminal inside the socket.

Description of the drawings:

FIG. 1 is a schematic wall socket side wall grounding diagram;

FIG. 2 is a schematic diagram of wall socket spring back grounding;

fig. 3 is a schematic diagram of wall socket back grounding.

The utility model discloses a concrete implementation mode:

1. as shown in fig. 1, 1) a metal grounding elastic sheet communicated with a ground wire terminal is arranged on the side wall of the wall socket contacted with the wall, and the elastic sheet can pass through the socket shell and automatically and directly contact with the wall by virtue of elasticity after the socket is installed, so as to realize primary grounding; 2) the elastic pieces can be arranged on the upper side wall, the lower side wall, the left side wall and the right side wall of the socket shell, and are only suitable for the concealed socket embedded in the wall body; 3) the elastic sheet can also be arranged on the back of the socket, and the socket is suitable for both open installation and concealed installation; 4) only one spring plate can be arranged, and a plurality of spring plates can also be arranged.

2. As shown in fig. 2, 1) a spring card slot is arranged near a ground wire terminal on the back surface of the wall socket, a ground spring can be arranged at the spring card slot, the card slot is used for facilitating the installation of the spring, preventing the spring from falling off and communicating the ground wire and the spring, and the spring can be directly contacted with the wall by virtue of elasticity after the socket is installed, so as to realize primary grounding; 2) the socket is provided with a spring penetrating opening which needs to be reserved on a rear shell; 3) the method is suitable for both the surface mounting and the concealed mounting of the socket.

3. As shown in fig. 3, 1) a grounding metal sheet connected with a ground wire is arranged on the back surface of the wall socket so as to be in contact with the wall after installation to realize 'primary grounding'; 2) the metal sheet with the rear shell may also be placed on the rear shell.

4. The primary grounding can also be realized by arranging a grounding screw connected with the ground wire, namely, the screw is connected with the ground wire and is embedded into the wall after being installed.

5. The grounding object in the scheme can be in various modes such as a metal elastic sheet, a spring, an elastic thimble and the like, and the shape of the grounding object is not limited so as to be suitable for grounding and convenient to install.

6. The above schemes can be used singly or in a mixed way.

7. In the above scheme and schematic diagram, only the standard 3-hole socket is drawn, and in the actual implementation, the wall socket including the 2-hole socket, the switch, the USB interface and the like is also included and applied.

8. The main differences between the metal elastic sheet in the embodiment 1 or fig. 1 and the metal grounding sheet in the embodiment 3 or fig. 3 are whether the metal elastic sheet has elasticity, the area size, whether the metal grounding sheet is fixed, and the like.

9. All the above solutions are to achieve "primary grounding" as much as possible, and do not guarantee absolute grounding or reach the national standard of grounding, such as: when the socket is installed on an insulating material such as a wood board or the like or an earthing object is too far away from a wall or an insulator is arranged in the middle of the socket, the socket is ineffective, namely the scheme reduces risks by 'primary earthing automatically as much as possible', but does not ensure absolute safety earthing and eliminates risks.

10. Although the scheme can realize the 'primary self-grounding' of the wall socket, when the wall socket is installed, if the ground wire is laid, the ground wire is connected according to the regulations.

The utility model has the advantages that: the wall socket has the advantages that the risk is reduced by enabling the wall socket to have the 'automatic primary grounding as much as possible', so that the wall socket also has certain grounding characteristic even under the condition of no ground wire, the safety coefficient is improved, and the construction complexity is reduced.

The purpose of this application is to improve safety awareness for urging people.
