Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device, and more particularly to a wiring device in which a plug and an outlet are rotatably connected.

[0002]

2. Description of the Related Art Conventionally, outlets connected to indoor wiring are mounted on wall surfaces, and various electric devices such as TVs, refrigerators, vacuum cleaners, washing machines, irons, microwave ovens, and heating appliances fixed on the wall are installed. When used, the plug at the tip of the cord for connecting to the electric device was inserted into the outlet to be connected. The plug connected to the cord is an elongated plate-shaped contactor having conductivity, and the plate surface is symmetrically faced to project.
Inserting holes into which the respective contacts of the plug can be respectively inserted are arranged on the left and right, and inside the inside, there is provided a contact having conductivity so that the contact can be held.

[0003]

The plug must be inserted into and removed from the outlet in a state parallel to the lengthwise direction of the contactor, which limits the directionality. Therefore, depending on the installation position of the furniture, the outlet may be located near the furniture, which makes it difficult to insert and remove the plug.

Refrigerators, TVs, washing machines, heating appliances, etc. are stationary, so they are not often pulled out while in use after being plugged into an outlet, but vacuum cleaners, irons, fans, and movable heating. For equipment, etc., the plug was inserted into the outlet at the beginning of use, and the plug was removed after use. Therefore, plugs are often inserted and removed.

When the plug is repeatedly inserted and removed as described above, the plug insertion / removal direction is limited as described above. Therefore, when the plug is removed in particular, it may be shaken to the left or right when it is difficult to pull it straight out. . However, if it is forcibly pulled out, the contactor is pulled out in a bent state, which is inconvenient for the next use. In particular, in such a case, the outlet itself may be broken, and the contactor in the insertion hole also fails, which is a cause of poor contact.

In the case of an electric device such as a vacuum cleaner that is used while moving in a room, when the cord is fully extended, the plug may be impacted and the plug may be forcibly pulled out. Problems were easy to occur. Even if the plug could not be pulled out due to impact, a lateral pulling force was applied to the cord at the connection point with the plug, which also caused disconnection of the cord at this connection point.

There is provided a wiring device in which a plug and an outlet are integrally connected so that both contacts are conductive, and the outlet can be rotated up and down with respect to the plug. In this case, the plug is connected to an outlet on the wall surface, and the plug of the electric device is inserted into the outlet of the wiring device to be connected. Such an outlet has the advantage that the plug of electrical equipment can be easily inserted and removed by turning the outlet upward, but it is not possible to extend the cord in use as in the above-mentioned vacuum cleaner. Since it is with respect to the direction, the problem cannot be solved in the case of an outlet that rotates only up and down, and bending of the plug contactor, destruction of the wall outlet, disconnection, etc. cannot be prevented.

In view of the above-described relationship between the wall outlet and the plug when using various electric devices, and various problems such as a wiring device in which the plug and the outlet are integrated, the present invention provides a plug and an outlet. It is an object of the present invention to provide a wiring device which is electrically conductively connected and whose outlet is rotatable in a direction of 360 ° with respect to a plug.

[0009]

In order to achieve the above object, the present invention provides a plug 2 connectable to a wall outlet.
And an outlet 3 to which a plug of an electric device can be connected. The front surface of the plug 2 on the side opposite to the contactor 4 and the outlet 3 are superposed and electrically conductively connected to the shaft 6, and the outlet 3 has an insertion hole. It is characterized in that the rotary shaft 5 can be rotated in a direction orthogonal to the rotary shaft 6.

[0010]

An embodiment of the present invention will be described in detail below with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 denotes a wiring device body according to the present invention, and the wiring device body 1 is formed of a plug 2 and an outlet 3. The plug 2 has the same structure as the conventional one in which two contacts 4 are projected in parallel, and can be connected to a wall outlet. Further, the outlet 3 has the same structure as the conventional one, which has a contactor capable of inserting a contactor of a plug of an electric device inside the insertion hole 5.

The plug 2 and the outlet 3 have their joint surfaces overlapped with each other on the surface opposite to the contact 4 of the plug 2 and the shaft 6
, And the outlet 3 is 360 with respect to the plug 2.
It can be rotated at a rotation angle of °. The plug 2 and the outlet 3 are electrically connected to each other in the connecting portion.

In the above structure, the plug 2 is connected to an outlet provided on a wall surface (not shown) in the same manner as the conventional one.
A plug for connecting to various electric devices with a cord may be inserted into the insertion hole 5 of the outlet 3 and connected.

With respect to the plug 2 fixed to the wall outlet, the outlet 3 can rotate the insertion hole 5 by 360 ° in the direction orthogonal to the connecting shaft 6, so that the cord extends during use of the cleaner. In such a case, the outlet 3 rotates in the pulled direction with the plug of the electric device connected. Further, when the cord is pulled, the plug can be pulled out straight from the outlet 3.

[0014]

According to the present invention described above, the plug 2 and the outlet 3 which are electrically connected to each other inside are integrally connected, and the outlet 3 is provided with the insertion hole 5.
Since the plug can be rotated at an angle of 360 ° toward the outside, the plug 3 fixed to the wall surface is fixed to the plug 2.

Therefore, when the electric equipment is used, the outlet 3 can be turned in response to the movement of the cord. Therefore, when the cord is pulled, an unreasonable impact is not given to the plug 2 with respect to the wall outlet, and no connection failure or disconnection occurs.

Further, when the cord is fully extended during use of the electric device, the outlet 3 is oriented in the extension direction of the cord. Therefore, if the cord is forcibly pulled, the plug of the electric device can be easily pulled from the outlet 3. Will be extracted by
No unreasonable force is applied to the plug 2 or the outlet 3.

Furthermore, since the orientation of the insertion hole 5 of the outlet 3 can be freely selected in the direction of 360 °, when the wall outlet is installed close to furniture and it is difficult to use, the insertion hole 5 of the outlet 3 is used for furniture. By pointing in the opposite direction, the plug of the electric device can be easily inserted and removed.
