A second bending-up unit(58) is formed by being vertically bent from the first bending-up unit toward the inner side filled with an insulating material(56). A third bending-up unit(60) is formed by being vertically bent from the second bending-up unit toward the cavity side for being parallel to the first bending-up unit. Then, a fourth bending-up unit(62) is formed by being vertically bent from the third bending-up unit toward the front surface of a main body for maintaining a gap from the second bending-up unit. An elastically contacting unit(64) is formed by being vertically bent from the fourth bending-up unit toward the cavity side while being parallel with the first bending-up unit. Moreover, a fifth bending-up unit is formed by being bent upwardly from the elastically contacting unit. Herein, the end unit of an internal phase(48) is vertically bent toward the insulating material for having an inserting unit(68) extended upwardly. Therefore, the inserting unit is inserted to an inserting groove(66) formed in the cabinet.
