  In general, for example, in order to supply power to an electronic device, a power plug of the electronic device is inserted into an outlet provided in the building. However, the length of the power cord attached to an electronic device, etc. is fixed. If the power cord does not reach from the place where the electronic device is installed to the outlet of the building, a power source having a so-called power connection part (receptacle or outlet) Power is supplied to various electronic devices via a connection device (extension cable).

  Further, when a plurality of power supplies are required for OA electronic devices or the like, a power connection device having a plurality of power connection portions is used, and power is supplied by inserting a power plug of each electronic device into the power connection portion. .

  The power connection device includes an extension cord having a plug at one end, a synthetic resin case provided at the other end of the plug, and a plurality of power connection portions including a pair of blade receiving terminals incorporated in the case. Become.

  However, in the conventional power connection device having such a power connection portion, the main body of the power connection device is integrally formed. The size of the main body of the power connection device is increased, which limits the installation location of other electronic devices and is not suitable for space saving.

  Therefore, an object of the present invention is to solve the problems of the prior art described above.

  In order to solve the above-described problems, the present invention employs a basic structure in which the main body of the power connection device is foldable, that is, movable.

  According to the present invention, there is provided a power connection device having a plurality of power connection portions, wherein the main body of the power connection device has a movable structure.

  According to the power connection device of the present invention, the main body of the power connection device can be folded and used. Therefore, the longitudinal dimension of the main body is shortened, and various electronic devices can be connected in a small space.

The power supply connecting device 1 includes an elongated box-shaped main body 2, a cord 4 having a plug 3 for insertion into a power source at one end, and a power source electrically connected to the electric wire of the cord 4 and housed in the main body 2. It has a pair of blade receiving terminals 5 as connecting portions.
The main body 2 includes a first main body 6 and a second main body 7 that is rotatably supported by the first main body 6. The first main body 6 and the second main body 7 are coupled by a rotating device 8 so that the second main body 7 can be folded onto the first main body 6 with the cord 4 as shown in FIG.

The main body 2 has an elongated box shape and is formed of a synthetic resin material. The side portion has a plurality of spaced apart openings 9, and the blade receiving terminal body 10 is arranged so as to close the openings 9.
As shown in FIG. 4, the blade receiving terminal body 10 as a power supply connecting portion is composed of a synthetic resin material block having a conductive blade receiving terminal 5 inside, and this block is engaged with the region of the opening 9 according to a conventional method. The terminal is connected to the wire of the cord 4.

  Velcro tapes 11 and 11 are attached to one ends of the first and second main bodies 6 and 7 so that the folded shape can be maintained.

  As shown in FIG. 5, the rotating device 8 includes a plate-like first arc portion 12 extending inwardly from the outer surface to the end portion of the first main body 6 divided vertically, A second arcuate portion 13 extending from the center of the end of the second main body 7 divided in the vertical direction, and the inner circumferential surface of the second arcuate portion 13 is the outer circumference of the first arcuate portion 12. The two main bodies 6 and 7 can be rotated by being in sliding contact with the surface. Note that the electric wire connected to the cord 4 may be brought into the second main body 7 through a hole formed in a part of the arc portion 12.

  In the example shown in FIGS. 1 to 3, the blade receiving terminal body 10 provided on the side of the first main body 6 and the blade receiving terminal body 10 disposed on the second main body 7 are folded in opposite directions. Sometimes (see FIG. 3), it becomes possible to insert plugs of electronic devices or the like from both sides.

6 and 7 show a second embodiment. In the example shown in FIG. 6 and FIG. 7, when the blade receiving terminal body 10 is arranged on the flat portions of the first and second main bodies 6 ′ and 7 ′ and folded, the blade receiving terminal body 10 is exposed to the upper and lower surfaces. Arranged to face.
The rotating device 8 'includes a pair of hollow blocks 14 and a locking portion 15 provided at the ends of both halves of the main bodies 6' and 7 '.

The block 14 has cylindrical projections 16 and 16 with flanges, and an electric wire enters the block 14 from one projection 16 and comes out to the other projection 16, and from one body 6 ′ to the other body 7 ′. Wired to
An annular groove is formed on the protrusions 16 and 16 by a flange.
Both the main bodies 6 'and 7' are composed of upper and lower halves, and end portions of the halves are formed with semicircular groove portions 17 facing each other as shown in FIG. The upper and lower groove portions 17 of both the main bodies 6 ′ and 7 ′ are fitted in the grooves of the projecting portions 16 of the blocks 14, 14 facing each other, and the halves are screwed to the block 14. The main bodies 6 'and 7' are made rotatable.

  As shown in FIG. 7, when the second main body 7 ′ is rotated below the first main body 6 ′ and both the main bodies 6 ′ and 7 ′ are stopped by the magic tape 11, the blade receiving terminal 5 is opened in the vertical direction. It becomes the shape that was made.

It is a top view of the power supply connecting device of an example of the present invention. It is a front view of the example shown in FIG. It is a front view which shows the folding state of the example of FIG. It is a top view of a blade receiving terminal body. It is a fragmentary sectional view which shows the rotation apparatus of the example of FIG. It is a top view of another example of the present invention. It is a front view which shows the folded state of the example of FIG. It is a front view of the block of the rotation apparatus used for the example of FIG. It is a fragmentary perspective view which shows the part engaged with the block of the half body of a 1st and 2nd main body.
