<p><P>PROBLEM TO BE SOLVED: To provide a first socket, a second socket, a first plug, a second plug and a socket having connection compatibility while ensuring safety. <P>SOLUTION: The other end opposite to one end of a plug fixture portion 110D to which a top end enlarged diameter part insertion portion 110C of a high pressure socket body top end side section 210 is connected, is connected to an enlarged diameter insertion part 210E having an inner diameter enough large to receive a first enlarged diameter part 324 of a low pressure plug 3 therein. A second enlarged diameter part 325 having a diameter larger than the inner diameter of the enlarged diameter insertion part 210E of the high pressure socket 2 is connected to the other end opposite to one end of the first enlarged diameter part 324 connected to a reduced diameter part 323 of the low pressure plug 3. Accordingly, the second enlarged diameter part 325 of the low pressure plug 3 makes contact with an opening portion 110A of the high pressure socket 2, and it is possible to prevent the whole of a low pressure insertion part 320 from being inserted into the high pressure socket 2. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
