Description

  The present invention relates to a power connection device having a movable power connection.

  In order to connect power plugs of electronic devices such as personal computers, printers, monitor TVs, modems and other office automation equipment, or household electrical appliances, stereo units, CD players, AC adapters, etc. A power connection device having a plurality of power connection portions (receptacles, outlets) is used.

The length of power cords with plugs for electronic devices and household electrical appliances is determined and shipped in advance, but depending on the installation location of these devices, the plugs of the power cords do not reach the power source installed at a fixed position in the building There are many cases.
In this case, a power supply connection device is interposed between the power supply at a fixed position and the plug of the power cord of the electronic device or household electric product to supply power to the electronic device or household electric product.

  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.

  The power supply connecting portion of the power supply device described above has a plurality of pairs of blade receiving terminals individually connected to the power supply of the extension cord pair, and the blade receiving terminals are connected through a pair of openings provided in the case. It is electrically connected to the inserted plug and can supply power to electronic devices and household electric appliances.

The opening for receiving the blade of the plug provided in the case is formed in the outer wall of the case, and the direction is fixed.
For this reason, depending on the installation location of an electronic device or household electrical appliance, the orientation of the plug of the power cord may not match the orientation of the opening of the case, causing inconvenience in inserting the plug into the opening, and the power cord This is not desirable because it causes twisting and risk of disconnection.

  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 makes a plurality of movable parts in the case main body of the power connection device, and a pair of openings for receiving the blades of the plugs in the power connection part (outlet) as these movable parts, A configuration is adopted in which blade receiving terminals that cooperate with the openings are arranged.

  In this configuration, each power connection portion can be moved with respect to the case body, the opening can be directed to the direction of the power plug, the plug can be easily inserted, and the power cord can be prevented from being twisted.

  According to the present invention, a case main body having a pair of conductors connected to a case via a cord and electrically connected to the cord therein, a pair of blade receiving terminals, and a blade of a plug of another device It has a power supply connection part having a pair of openings that can be inserted, and the power supply connection part is movable with respect to the case body in a state where each conductor and the corresponding blade receiving terminal are electrically connected. Is provided.

  According to the present invention, since the power supply connecting portion is movable with respect to the case body, the direction of the opening for inserting the plug blade can be directed in an arbitrary direction. The plug cord is not twisted and the risk of disconnection can be eliminated.

  As shown in FIGS. 1 and 2, the power connection device 1 includes a cord 3 having a plug 2 at one end and a case 4 connected to the other end of the cord 3. The case 4 includes a case main body 5 as a stationary member and a plurality of power supply connection portions 6 pivotally supported with respect to the case main body 5.

  The case body 5 is made of synthetic resin, and includes a plurality of spaced wall portions 7, a flat portion 8 that joins the bottom portions thereof to each other, and a pair of spaced apart elongated conductive plates 9 and 10. The positive and negative wires of the cord 3 are connected to each other (see FIG. 2).

  Each power connection portion 6 movably disposed between the wall portions 7 of the case body 5 has a box shape made of a synthetic resin, and a pair of claw receiving terminals 11 and 12 disposed therein, an electronic device, It has an opening 16 and 16 for receiving a blade of a power plug for household electric appliances and electrically connecting the blade to terminals 11 and 12 made of a conductive material (see FIGS. 1 and 3).

A plurality of substantially L-shaped fixed terminals 13 made of a conductive material are fixedly spaced apart from each other on the conductive plate 9. A plurality of substantially L-shaped fixed terminals 14 made of a conductive material are fixedly spaced apart from each other on the conductive plate 10.
The fixed terminal 13 is embedded in one side surface of the wall portion 7, and the fixed terminal 14 is embedded so as to face the side surface of the facing wall portion 7.

The fixed terminal 13 and the blade receiving terminal 11 are held in an electrically connected relationship and relatively movable using a caulking pin 15 made of a conductive material. The fixed terminal 14 and the blade receiving terminal 12 are held in an electrically connected relationship and relatively movable using a caulking pin 15.
As a result, each power supply connection portion 6 can be rotated 180 degrees with the space between the wall portions 7 and 7 adjacent to the flat portion 8 of the case body 5 as an angle (see FIGS. 1, 4 and 5). .

  For electrical connection between the blade receiving terminals 11 and 12 and the fixed terminals 13 and 14, it is preferable to provide a protrusion on one terminal so that the contact between the two is elastic. Thereby, the electrical contact of both terminals by the caulking pin 15 and the protrusion is possible.

  In use, a plug claw of an electronic device or an electric product is inserted into the openings 16 and 16, and the blade is brought into contact with the blade receiving terminals 11 and 12. The blade receiving terminals 11 and 12 are electrically connected to the fixed terminals 13 and 14, the conductive plates 9 and 10, and the plug 2 via caulking pins 15 and 15 and / or protrusions (not shown), so that power can be supplied. To do.

  Since the power supply connecting portion 6 can be rotated 180 degrees (angle) in an arbitrary direction, the direction of the openings 16 and 16 can be freely selected, which is very convenient.

It is a perspective view of the power supply connecting device of an example of the present invention. It is a top view of the example shown in FIG. It is a fragmentary perspective view which shows the structure of a power supply connection part and its periphery. It is sectional drawing seen from the arrow IV-IV of FIG. It is sectional drawing seen from the arrow VV of FIG.
