Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an outlet mainly used at temporary construction sites and the like.

[Background technology] Conventionally available electrical outlets require the body to be attached to a wall, etc. using two or more mounting screws with the cover removed, and then the cover is attached to the body. It was like that. Therefore, the installation work is troublesome, and it is inconvenient to attach and detach when only temporary fixing is required, such as when used at a temporary construction site. The purpose is to provide an outlet that can be easily attached to and detached from the mounting surface when used temporarily fixed at a temporary construction site or the like.

[Disclosure of the Invention] (Structure) The outlet according to the present invention includes a body having a blade insertion opening opened on the front side into which the blade of the plug is inserted, and a body that is housed in the body in correspondence with the blade insertion opening. A single installation device that includes a blade holder spring that is electrically connected to the blade of the plug, and a terminal part that connects an external electric wire to the blade holder spring, and into which a mounting screw is inserted to attach the container body to a wall surface, etc. Holes are formed through the front and back of the vessel, allowing for easy attachment from the front of the vessel using only one mounting screw.

(Example 1) As shown in FIG. 3, the container body 1 has a body 11 and a cover 12, which are both made of an insulating material such as synthetic wood, with a tapping pin inserted through a through hole 16 from the back side of the body 11. They are connected by screws 13 to form a rectangular parallelepiped shape. A partition 14 is formed inside the body 11 to separate the inside of the body 11 into left and right sides along the direction of the technique, and blade receiving springs 2 are disposed on both sides of the partition 14, respectively. Each of the blade receiving springs 2 includes a pair of blade receiving parts 21, and terminal frames 22 forming terminal parts are formed at both ends in the longitudinal direction. A lock spring 23 having a locking piece 24 is housed in each terminal frame 22, and the external electric wire 3 can be held between the locking piece 24 and the terminal frame 22. Two grooves 15 are formed at each end of the body 11 in the longitudinal direction, and a portion surrounded between the circumferential surface of the groove 15 and the cover 12 introduces the external electric wire 3 into the container body 1. This becomes the wire insertion hole 7.

That is, the wire insertion holes 7 are opened at both longitudinal end surfaces of the container body 1. A release button 3 is located near the wire insertion hole 7.
0 is placed. The release button 30 includes an operation piece 31 having an operation surface large enough to be pressed with a finger, and a lock piece 2 of a lock spring 23.
4 and the engagement recess (not shown) formed on the inner circumferential surface of the cover 12.
It has a fulcrum protrusion 33 that serves as a support of 0.0.

The cover 12 is formed with a plug insertion hole 17 into which the blade of the plug is inserted at a position corresponding to the blade receiving part 21 of the blade receiving spring 2, and a recess is formed at a position corresponding to the operating piece 31 of the release button 30. An exposure window 19 is formed at the bottom of the recess 18 to expose the operation piece 31 to the front side of the cover 12. Further, a notch 20 is formed in the Wi layer portion of the cover 12 in the longitudinal direction at a position corresponding to the groove 15 of the body 11. When the cover 12 is fitted onto the body 11, the front surface (the upper surface in FIG. 1) of the operating piece 31 of the release 1fJ30 is set to be located further down than the front surface of the cover 12. The lock button 30 is slidable in the operator's direction of the cover 12, and the release button 30 is slidable within the sliding range.
When the button is located at the operating position near the center of the cover 12, the pressing protrusion @32 comes into contact with the lock piece 24 of the lock spring 23, and the release button 30 is located at the standby position near the outside of the cover 12. The pressing protrusion 32 is set to be separated from the lock piece 24 of the lock spring 23 when the lock spring 23 is located at . That is,
A return spring 35 made of a coil spring is interposed between the inner peripheral surface of the cover 12 and the base of the pressing protrusion 32 of the release button 30, and urges the release button 30 to the standby position. Release button 30 when no external force is applied
is pressed by the return spring 35 and located at the standby position. Therefore, in order to press the locking piece 24 with the release button 30, first release #3 is pressed against the spring force of the return spring 35.
0 to the operation position with your finger, the release button 30 rotates around the four protrusions 33 and releases the lock spring 23.
The lock piece 24 is pressed. As a result, lock piece 2
4 and the terminal frame 22 of the blade holder spring 2, and the external electric wire 3 that has not been connected to the blade holder spring 2 can be easily removed. That is, the external mold #i3 can be removed simply by manually pressing the release button 30 while the container body 1 is attached to a mounting surface such as a wall surface. In addition, since the release button 31 is recessed from the front of the container body 1, it is possible to prevent the external mold a3 from accidentally coming off due to some object hitting the release button 30, resulting in a highly safe product. becomes.

As shown in FIG. 1 and FIG. 2, the container body 1 is provided with one mounting hole 4 r&, which passes through the body 11 and the cover 12. By inserting the mounting screw 5 into the mounting hole 4, the body 1 is attached to a mounting surface 6 such as a wall surface, and the mounting screw 5 is designed to be compatible with various types of wood screws such as countersunk screws and pan head screws. The dimensions of the mounting hole 4 are set in . With the above configuration, the container body 1 can be attached to the mounting surface 6 with one mounting screw 5, so that workability is improved.

With the above configuration, when connecting the external electric wire 3, as shown in FIG. 24 and the terminal frame 22, the external wire 3 and the blade receiving spring 2 are electrically and mechanically connected, and when the external mold #i3 is removed, When the release button 30 is pressed in the above-described manner, the locking piece 24 is bent to release the external mold #13 from being held, and the external electric wire 3 can be easily removed.

(Embodiment 2) By the way, since the above-mentioned outlet has wire insertion holes 7 at both ends of the device body 1 in the operator's direction, one wire insertion hole 7 can be used for external wiring from the power source side! It is conceivable to connect the wires 3 and 3 and connect the feeder external arrangement a3 to the other wire insertion hole 7 to connect them one after another. In this case, since the external wire 3 will no longer be connected to the wire insertion hole 7 of the outlet located at the end, it is desirable to close it with a closing plate 8 to prevent foreign matter from being inserted. In this example,
It is done in a hazy manner.

As shown in FIG. 5, the closing plate 8 is formed in a rectangular shape, and has engaging protrusions 8a on a pair of opposite sides, and cutouts 8b on a pair of adjacent sides, and is made of polyethylene or the like. Made of flexible material.

On the other hand, a recess 9 into which a closing plate 8 can be fitted is formed around the wire insertion hole 7, and an engaging hole 7a that can be engaged with an engaging protrusion 8a is formed in the peripheral wall of the recess 9. There is. Therefore, when the closing plate 8 is attached to the wire insertion hole 7, the engaging protrusion 8a
is engaged with the engagement hole 7a, and the closing plate 8 is held in the container body 1 with the electric wire insertion hole 7 closed. This structure prevents the tip of the driver from being inserted into the wire insertion hole 7, and prevents electric shocks and short circuits due to the insertion of foreign objects. To remove the closing plate 8, the tip of a screwdriver or the like can be inserted into the notch 8b and rubbed.

[Effects of the Invention] As described above, the present invention includes a container body in which a blade insertion opening for inserting a plug blade is opened on the front side, and a container body that is housed in the container body corresponding to the blade insertion opening and a plug blade insertion opening into which a plug blade is inserted. It is equipped with a blade holder spring that is electrically connected to the blade, a terminal part that connects an external electric wire to the blade holder spring, and one mounting hole into which a mounting screw for attaching the container to a wall surface, etc. is inserted. It is formed through the front and back of the vessel body, and one mounting hole is formed through the body from the front and back, so only one mounting screw is inserted from the front side of the vessel body. This makes it easy to attach to the desired mounting surface, and when only temporary fixing is required, such as when used at a temporary construction site, the advantage is that it is easy to attach and detach from the mounting surface and has good workability.
