Description

Electric socket to disconnect completely the electricity flow without ejecting the electric plug from it}

An example of an electrical socket that can block the flow of electricity without unplugging the electrical plug implemented in the present invention is shown in FIG.

The top view of the top of the electric socket of FIG. 2 is an arc shaped slot groove 4 having a constant width in the circumferential direction of the round shape at both ends of the shape of the two slot grooves in the electric socket into which the electric plug terminal of the electric socket plastic top surface is inserted. Mold.

If only the electric plug terminal is inserted into the electric socket (when the electric plug terminal center axis is in position 1), do not allow electricity to pass through, insert the electric plug terminal, hold the handle of the electric plug, and rotate it a circumferential direction. (3) Make the energization terminal 7 inside the socket close to the electric plug terminal (when the electric plug terminal center axis is in position 2) so that energization is made.

To this end, as shown in the structure of the electrical socket bottom contact portion of FIG. 3, a leaf spring having elasticity in the direction of rotation of the electric plug is used on the outer surface of the electric socket and the bottom of the child protection barrier as opposed to the form of plugging or pulling in a direction perpendicular to the socket as in the past. To process the live terminal 7 inside the socket.

Most of the general technologies such as plastic molding technology applied to the present invention, and an electric conduction terminal structure for forming a close contact surface are commercially applied.

In addition, the component to be applied to the present invention can be produced only by changing the mechanical shape or physical properties required in the existing electrical socket products.

The present invention is to solve the following problems through the invention of the electric socket that can block the flow of electricity without pulling the electric plug.

If the electric plug must be pulled out in order to physically block the electric flow completely from the existing socket so that no electric flow occurs, the factor that causes the electric plug or the wire to become entangled or inconvenient for cleaning and does not give an aesthetic appearance do.

In order to completely block the flow of electricity in the existing socket, it is possible to install a separate electrical disconnect switch and turn it off or on, but the socket manufacturing cost will increase considerably.

In particular, if you operate an electrical disconnect switch on a multi-tap with two or more sockets connected to one or more electrical outlets or multiple sockets connected to one or more electrical outlets, you will be able to control the electrical Unavoidable inconvenience occurs.

Often, when the electrical socket is plugged into the wall of furniture or electronics, it is almost impossible to pull the electrical plug out of the electrical socket in a direction perpendicular to the surface of the electrical socket because of the narrow gap which is hard to reach. It is easy to lack the power to pull the plug by hand into an impossible or limited space.

Means for solving the above problems are as follows.

It is possible to change the shape or physical characteristics of the existing electric socket without a separate electric flow blocking device, and to hold the simple electric plug handle without removing the electric plug, and to use it to enable electric current or to physically block the electric flow. Can be.

The electric plug terminal insert slot groove in the existing electric socket is formed into an arc-shaped slot groove having a constant width along the circumferential direction, and one end of the arc is not provided with an electric conduction terminal in the electric socket. The electric plug terminal and the energizing terminal in the electric socket are mechanically inserted at the position where the electric plug reaches the other end by simply plugging in the electric plug and holding the handle of the electric plug and rotating the electric plug. It is in close contact so that electricity can flow.

Holding the handle of the electric plug and rotating the electric plug in the opposite direction releases the mechanical interference between the electric plug terminal and the live terminal in the electric socket and, if necessary, cuts off the child protection between the top of the electric socket and the live part. Make sure that the plug can be pulled out to overcome the friction of the plate.

The effects that can be expected through this invention are as follows.

When unplugging the electric plug into the electric socket, grab the electric plug handle and simply rotate the electric plug to remove it, and then use the rotational force to overcome the friction force of the barrier plate without using excessive force in the vertical direction of the electric socket. With little force the electrical plug can be disconnected from the electrical socket.

Even when the electric plug is plugged into a small gap that is difficult to reach, the electric plug is inserted into the slot of the electric plug terminal insertion slot correctly. Can be plugged in easily. Even when removing the electric plug, hold the electric plug handle to release the force between the current carrying terminal of the electric socket and the electric plug terminal, and then release the electric plug from the electric socket with a force that is small enough to overcome the friction of the blocking plate. Can be separated.

Specific details for the implementation of this invention are as follows.

The energizing terminal 7 arranges an energizing terminal having elasticity at both sides of the slot groove at an interval narrower than the diameter of the electric plug terminal, and the electric plug seat slot groove 6 such as a bud shape so that the electric plug terminal is in close contact with the energizing terminal. Are machined or molded on both sides along the circumferential direction of the arc.

The shape of the blocking plate may be manufactured in the shape indicated by the hatch of 4 so as to incline around the plug terminal insert slot 5 and the remaining portion may be molded in a planar state.

If necessary, if the electrical plug is rotated in the opposite direction to the terminal insert slot groove (5) position, so that the electrical plug is not completely disconnected from the electrical socket and is only disconnected from the electrical socket, to prevent the electrical plug from leaving the socket, As shown in the hatched portion of Fig. 5, the block 4 is formed by removing a circle or convex half-moon shape having a size slightly smaller than the circle size of the electric plug terminal insertion slot groove 5. The electrical plug terminals can be brought into close contact with the widest possible area. The barrier plate also forms an inclined surface in the opposite direction from the seat slot groove (6) of the electric plug terminal to the terminal insert slot groove (5) to easily position the electric plug terminal in the slot of the terminal insert slot and insert the electric plug terminal. When pushed in order to prevent the insertion plate is automatically pushed to rotate the insertion area.

If necessary, the spring force of the existing barrier plate restoring spring is increased to increase the force on the side to prevent the electrical plug terminal from randomly leaving the electrical socket.

After the initial electrical plug terminal is easily inserted, and the plug is rotated for seating (3), as shown in FIG. 6 in order to prevent the electrical plug terminal from being easily detached from the energizing terminal 7 inside the socket. The diameter of the electric plug terminal insert slot groove 5 is larger than the diameter of the electric plug seat slot groove 6 and the diameter of the electric plug seat slot groove 6 is close to the electric plug terminal outer diameter within the tolerance range. Mold.

After inserting the electric plug terminal and rotating it for seating (3), the electric plug terminal insert slot groove as shown in FIG. 7 in order to prevent the electric plug terminal from being easily detached from the energizing terminal 7 inside the socket in the seated state. The upper surface of the electric socket can be molded to have a peanut shell shape by making the passage width between the terminal insertion slot groove and the seat slot groove smaller than the diameter of (5) or the seat slot groove (6). .

As shown in FIG. 4, in the case of the H-type socket to which a terminal for grounding is added, all three slot grooves are formed into arc-shaped slot grooves.

Industrial application of this invention has the following characteristics.

1) side of production cost

The electrical plug terminal insert is almost the same in cost compared to the conventional socket which has a circular shape. All of the applied parts are currently being applied to the socket, and there are no new parts. However, the current-carrying terminal and blocking plate restoring spring inside the electric socket, which may have a change in shape or physical properties compared to the existing socket, may be recovered by changing the shape of the connection part of the current-carrying terminal or reducing the molding volume of the internal plastic material. .

2) processability aspect

Although the shape of the current-carrying terminal inside the electric socket may be somewhat complicated, the structure capable of supporting the electric plug terminal can be simplified from a bud shape to an easy form.

3) safety aspects

Occasionally, the tolerance management of the electric socket and the electric plug is insufficient, thereby increasing safety by eliminating the risk of using excessive force in the process of unplugging the electric plug or damaging the user. In addition, since the electric plug is inserted into the socket to be rotated to become the energizing condition, it can be said that the protection function against electric shock of a child is also enhanced.
