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 integrally 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 is located near the furniture, so that the plug cannot be easily inserted and removed.

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 destroyed, and the internal contactor may also be broken, causing a contact failure.

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 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 an outlet integrated with the plug for connection.
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 that is integrally connected so that an outlet can be directed in a pulling direction of a cord due to movement of an electric device.

[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 outlet 3 is connected to the front side of the plug 2 in an orthogonal state so that the outlet 3 can rotate in the left-right direction and the plug 2 and the outlet 3 are electrically conductive. It is characterized by being connected as much as possible. Further, the present invention is characterized in that the plug 2 and the outlet 3 are superposed on each other at the joint surface and pivotally coupled so as to be rotatable.

[0010]

Embodiments of the present invention will now be described in detail with reference to the drawings. 1, 2 and 3 show an embodiment of the wiring device of the present invention, in each of which 1 is a wiring device body, and the wiring device body 1 is formed of a plug 2 and an outlet 3. ing.

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. On the front surface of the plug 2 opposite to the contactor 4, the outlet 3 having the contactor 6 inside the insertion hole 5 is connected in an orthogonal state and
Is rotatable in the left-right direction with respect to the plug 2.
A plug of an electric device can be connected to the outlet 3.

In order to make the outlet 3 rotatable, for example, a rotation guide body 7 is provided on the front side of the plug 2, and the base of the outlet 3 is fitted into this guide body 7 so as to be pivotally connected. However, other structures can be adopted as long as the plug 2 and the outlet 3 can be rotatably connected. Then, in the connection between the plug 2 and the outlet 3, both contacts 4 and 6 of the plug 2 and the outlet 3 are electrically connected.

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.

An outlet 3 for the plug 2 in the fixed state
Is rotatable in the left-right direction, so that the outlet 3 rotates in the pulled direction with the plug of the electric device being connected when the cord is fully extended during use while moving like a vacuum cleaner. . Further, when the cord is pulled, the plug can be pulled out straight from the outlet 3.

4 and 5 show another embodiment of the present invention,
The same parts as those in the above embodiment use the same reference numerals. In this embodiment, the plug 2 and the outlet 3 are vertically stacked and connected by the connecting shaft 8 penetrating therethrough. The plug 2 and the outlet 3 are rotatable on the joint surface around the connecting shaft 8, and the contacts 4 and 6 of the plug 2 and the outlet 3 are electrically connected at the connecting portion, as in the above embodiment. ing. With such a configuration, if the plug 2 is inserted into a wall outlet, it will be in a fixed state, and only the outlet 3 will rotate in the left-right direction.

[0016]

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 rotatable in the left-right direction. With respect to the plug 2 fixed and connected to the outlet, the outlet 3 becomes free.

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.

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.

Further, when the outlet 3 is folded with respect to the plug 2 or when the plug 2 and the outlet 3 are overlapped and rotatably connected like the wiring device of the second embodiment,
By orienting the insertion hole 5 of the outlet 3 in the direction of the contactor 4 of the plug 2, the overall volume can be reduced, so that the package can be compacted and not bulky.
