される。[Background Art] FIG. 4 shows an exploded perspective view of a multi-outlet used in an electrical equipment manufacturing line. This multi-outlet is configured so that multiple types of plugs can be inserted, since the power supply voltage and the shapes of plug blades and grounding rods are different in different countries. A pair of blade receiving springs 1a, 1b, . On the other hand, a pair of blade receiving springs 1e are similarly fixed onto a pair of L-shaped and conductive terminal plates 2b by fixing pins 7. A power line 8 is screwed and fixed by a screw 9 into a screw hole 10 formed in the terminal plates 2a, 2b, and the power line 8 is connected to the terminal plates 2a, 2b. The terminal plate 2b side is made to correspond to a domestic plug with a grounding rod (grounding electrode), and the terminal plate 2a side is made to correspond to a foreign plug with a grounding rod. An insulating partition wall 11 is integrally provided between the terminal plates 2a and 2b and protrudes from the upper surface of the body 3'. Terminal plates 2a and 2b to which each blade receiving spring 1a is fixed are arranged on the upper surface of a plate-shaped body 3' made of an insulating material. The cover 12', which is box-shaped and made of an insulating material with an open bottom, has plug blade insertion holes 4a corresponding to the blade receiving springs 1a, respectively.
... is perforated. And the punch insertion hole 4a...
An earth rod insertion hole 5a into which a plug earth rod (not shown) is inserted is bored near the plug. The body 3' and cover 12' are fixed with assembly screws 13.

棒の逃がし穴となつている。 The multi-outlet configured in this way is used in the production line of electrical equipment as mentioned above.
A plug with a grounding rod from an electrical device is attached. The plug has a plug blade and a grounding rod, but since it is used on a manufacturing line, there is no grounding electrode for receiving the grounding rod on the multi-outlet side, and the grounding rod insertion hole 5a... is simply a grounding rod. It has become an escape hole.

た。 Therefore, the conventional multi-outlet has a hole (earth rod insertion hole 5a...) in the molded product, that is, the cover 12'.
It is in a state where it is only open, and the different polarity terminal plate 2a
Since there is no partition wall between them, there is a problem that if a stapler needle or a metal piece enters through the ground rod insertion hole 5a during use, a short circuit will occur between the different electrodes.

It provides a multi-outlet outlet for the purpose.

である。[Disclosure of the invention] (Structure) The present invention is a multi-outlet having a pair of plug blades and a grounding rod into which multiple types of plugs can be inserted, and a blade receiving spring into which the blades of multiple types of plugs are inserted. A body made of insulating material with multiple types of terminal plates arranged, a plurality of plug blade insertion holes corresponding to the plug blades described above, and a ground rod insertion hole into which a ground rod is inserted, and the body covered. In a multi-outlet outlet consisting of a cover made of an insulating material, an insulating tube is integrally hung from the periphery of the grounding rod insertion hole of the cover to the body side, so that even if a stapler etc. gets inserted through the grounding rod insertion hole, it can be prevented. It is characterized in that it is inserted into an insulating cylinder, and the insulating cylinder prevents a short circuit between different poles in a live part such as a blade receiving spring or a terminal plate.

ある。(Example 1) Hereinafter, an example of the present invention will be described with reference to the drawings. Incidentally, since the overall configuration of the multi-outlet is the same as the conventional one, the gist of the present invention will be described in detail. FIG. 2 shows a plan view, and FIG. 1 shows a sectional view taken along the line AA in FIG. Further, although the number and position of the plug blade insertion holes 4a, the ground rod insertion holes 5a, etc. are different from the conventional ones, they are basically the same.

An insulating cylinder 6a whose lower surface is open from the lower surface of the peripheral edge of a...
are integrally protruded downward. Further, insulating cylinders 6b, whose upper surfaces are open, are integrally formed upward from the upper surface of the body 3 corresponding to the earth rod insertion holes 5a, respectively. The end surfaces of the two insulating tubes 6a, 6b are in contact with or close to each other to form a tube, and are insulated from the terminal plate 2a, blade receiving spring 1a, etc. Therefore, even if a stapler or a piece of metal enters the grounding rod insertion hole 5a, the insulating tube 6
It simply enters the cylindrical body constituted by a and 6b, does not come into contact with the terminal plates 2a, etc., and does not cause a short circuit between different poles.

The liquid is discharged from below the body 3 through the through hole 14. Therefore, in such a case, even if a needle or the like is inserted through the grounding rod insertion hole 5a, it will not enter the multi-outlet, but rather will be inserted into the insulating cylinders 6a, 6b and the terminal board 2a, etc., without contacting them at all. It is discharged to the outside through the through hole 14.

果を奏するものである。[Effects of the invention] As described above, the present invention is a multi-outlet having a pair of plug blades and a grounding rod into which multiple types of plugs can be inserted, and a blade holder spring into which the plug blades of multiple types of plugs are inserted. A body made of an insulating material is provided with a terminal board having multiple types of terminals, and a plurality of plug blade insertion holes corresponding to the plug blades described above are drilled, and a ground rod insertion hole into which a ground rod is inserted is drilled, and the body is covered. In a multi-outlet outlet consisting of a cover made of insulating material, an insulating tube is integrally hung from the periphery of the grounding rod insertion hole of the cover to the body side, so that staples etc. cannot be inserted from the grounding rod insertion hole. Even if it is inserted into the insulating cylinder, the insulating cylinder can prevent a short circuit between different poles in a live part such as a blade receiving spring or a terminal plate.
