For the table tap having 1,12, a two-pole socket hole 13 for one two-pole plug P ₂ is added to the blank portion in the middle of the two sets of common socket holes 11,12. [Effect] A 2-pole socket hole is added without increasing the conventional size, and up to 3 2-pole plugs can be used, and convenience of use is improved conveniently.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a table tap that can be commonly used for a two-pole plug and a three-pole plug.

[0002]

[Prior art]

 The electrical equipment is equipped with an electrode plug for the AC power supply, which is inserted into the socket hole of the table tap to receive power. Normally, the electrode plug has 2 poles, but if the power of the electrical equipment is large, or if it is grounded to protect the electrical equipment or to prevent danger, the 3 poles with 1 pole for grounding should be used. It is used. In Fig. 2 (a), (a) is a 2-pole plug P.₂ Shows two insert blades p against AC voltage_a, p_b Are provided at intervals d. (B) is a 3-pole plug P₃ Shows 2 pole plug P₂ With respect to grounding pin p_e Is added, both plugs P ₂ , P₃ Insert blade p_a, p_b The distance d is the same according to the JIS standard. FIG. 2 (b) shows an example of a common table tap 1 having two poles and three poles, each of which has two 3-pole plugs P.₃-1, P₃-2 or 2-pole plug P₂-1, P₂-2, so that the insertion hole (K_a1, K_b1) And (K_a2, K_b2), And the insertion hole E for grounding₁, E₂ 2 sets of common socket holes 11 and 12 are provided.

[Problems to be solved by the device]

Now, the common table tap 1 described above can use up to _two 2-pole plugs P ₂ . However, the number of 2-pole plugs P ₂ used may exceed 2, so we would like to add more socket holes. However, the table tap 1 is already large due to the three-pole plug P ₃ , and if it is made larger than this, the usability becomes poor. On the other hand, when the two-pole plugs P ₂ -1, P ₂ -2 are inserted into the respective insertion holes (K _a1 , K _b1 ) and (K _a2 , K _b2 ) as shown by the chain line in the figure, The grounding insertion holes E ₁ and E ₂ are not used, and a blank portion remains between P ₂ -1 and P ₂ -2. It is possible to add a socket hole for the bipolar plug P ₂ to this blank portion. The present invention has been made in view of the above, and an object thereof is to provide a two-pole / three-pole common table tap in which a socket hole for one two-pole plug is added to the blank portion of the common table tap 1 described above. To do. In addition, although the conventional table taps are "common", in the device of the present invention, the additional 2-pole socket is dedicated to the 2-pole plug, and all the socket holes are not common. For convenience, it is "shared".

[0004]

[Means for Solving the Problems]

 This invention is a two-pole / three-pole common table tap, and two sets of two-pole plugs or three-pole plugs each having a common socket hole into which two common poles can be inserted in common. A two-pole socket hole for one two-pole plug is added to the empty space in the middle of the common socket hole, and three two-pole plugs can be used.

[0005]

[Action]

 In the common table tap of this invention, up to two 3-pole plugs can be used as before, but with the addition of one 2-pole socket hole, up to three 2-pole plugs can be used. The selfishness is improved.

[0006]

【Example】

FIG. 1 shows an embodiment of the present invention. A 2-pole 3-pole shared table tap 1'according to the present invention is a blank space between two sets of common socket holes 11 and 12 of the common table tap 1 shown in FIG. A two-pole socket hole 13 composed of insertion holes K _a3 and K _b3 is added to the portion, and each is internally connected. In the common table tap 1 ', two 3-pole plugs P ₃ -1, P ₃ -2 or 2 pole plugs P ₂ -1, P ₂ -2 are provided for the common sockets 11 and 12 as usual. Although it can be inserted, one 2-pole plug P ₃ -3 can be inserted into the 2-pole socket 13 to improve the usability compared to the conventional one. However, if a mix of 3-pole plug P ₃ and 2-pole plug P ₂ is conventionally, each one by one can be used. As the power of the two-pole plug P ₂ is less than 3-pole plug P _3, is that there is no problem on the capacity of the strip also 2-pole plug P ₂ by adding one.

[0007]

[Effect of device]

 As described above, in the 2-pole / 3-pole common table tap according to the present invention, like the conventional 2-pole / 3-pole common table tap, up to two 3-pole plugs can be used. It is possible to use up to 3 2-pole plugs by adding 2-pole socket holes to the blank area without increasing the size, which greatly improves the convenience of use.
