ABSTRACT:
An insulator for a terminal-connecting portion has a sufficient force for holding a terminal and can drain water efficiently. An insulator body 100 is provided with a draining hole 140 on a side wall part 133 which is one of the exterior walls forming a curved portion 130. Since the draining hole 140 is provided on the side wall part, an outer corner wall part 131 of the curved portion 130 is left intact and an inner peripheral face of the outer corner wall part 131 is closely and elastically mounted on a corner 64 of a female terminal 60. Since an inner peripheral face of another end 120 of the insulator body 100 is closely and elastically mounted on two corners 62 and 63 out of three remaining corners 61 to 64, the female terminal 60 is supported on three points, so that a sufficient force of holding a terminal can be obtained. Further, it is possible to efficiently drain water such as rain or the like, which enters into the insulator body 100, from the draining hole 140, since the hole 140 can be formed into a large diameter.
