( Reference Example 2 )
As shown in FIG. 12, the table tap with a switch of the present reference example is one in which the switch 60 of the first embodiment is deleted and the three plug insertion ports 14 are always energized.

  In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.

( Reference Example 3 )
As shown in FIG. 13, the table tap with a switch of the present reference example has a body 121 composed of a body 122 and a cover 123 each formed of a synthetic resin having impact resistance, and inside the body 121 A middle case provided with six plug insertion holes 11 made up of a pair of plug blade insertion holes 12, a blade receiving spring for receiving a plug blade inserted into each plug blade insertion hole 12, and the surface of the container body 121 In accordance with the on / off operation of the switch operation unit 30c provided on the surface, six switches and the like for turning on / off the energization from the external power source to the pair of blade receiving springs are provided. Is linked to one plug insertion slot 11.

  The body 122 is formed in a rectangular box shape whose upper surface is open. On the other hand, the cover 123 is formed in a substantially rectangular box shape having an open bottom surface, and has an upper surface 123a narrower than the width of the container body 121 in the short direction, and the container body 121 from both side ends of the upper surface 123a in the short direction. Inclined surfaces 123b and 123c are formed along the longitudinal direction so as to approach the bottom surface of the body 122 toward both end portions in the short direction, and one of the inclined surfaces 123b and 123c in the short direction is formed. Each side end portion is continuous with side surfaces 123d and 123e formed along the longitudinal direction.

  In addition, the power cord 90 is introduced substantially at the center of the side wall on one end side in the longitudinal direction of the container body 121.

  The upper surface 123a of the cover 123 is formed with two rows of rectangular exposed windows 123f arranged in the longitudinal direction, and the pair of plug blade insertion holes 12 and 12 are exposed upward from the exposed windows 123f. . In addition, three rectangular exposed windows 123g are arranged along the longitudinal direction on the inclined surfaces 123b and 123c of the cover 123, and one switch operating portion 30c is inserted in each exposed window 123g. Each switch operation part 30c is interlocked with each plug insertion port 11 facing the upper surface 123a side.

In this reference example , since the six plug insertion ports 11 are exposed on the inclined surfaces 123b and 123c provided on both sides of the body 121, the plug blade is inserted on the side surface as shown in FIG. Compared with the case where the hole and the switch operation part are exposed, the plug insertion / removal to the plug insertion port and the operation of the switch operation part are facilitated. Further, as shown in FIG. Compared with the case where the operation part is exposed, it can be configured more compactly.

  In addition, the same code | symbol is attached | subjected to the structure similar to Embodiment 1, and description is abbreviate | omitted.
