<p>PROBLEM TO BE SOLVED: To prevent an opening/closing cover from being broken when it opens and closes an extension terminal and being removed by holding this cover detachably to a hinge part to cover the extension terminal and using a flexible material to the hinge part. SOLUTION: An extension connector boxes 30 and 40 are provided on the left side face 2R of a main body 2, and the connector terminals are put into the boxes 30 and 40. The hinge parts 51 and 61 of the opening/closing devices of the boxes 30 and 40 have the fixed base parts 53 and 63 and the shafts 54 and 64. The flexible material such as a plastic or rubber material is used to the parts 53 and 63. The comb-line projections 53B and 63B of the parts 53 and 63 are contrary to the projections 52B and 62B of the opening/closing covers 52 and 62. Then the shafts 54 and 64 are put through the holes 53A and 63A of the projections 53B and 63B and the holes 52A and 62A of the projections 52B and 62B respectively. Thus, the covers 52 and 62 can rotate around the shafts 54 and 64 against the parts 53 and 63 of the parts 51 and 61.</p> |
