Terminal fitting
A terminal fitting ( 1 ) includes a rectangular tube ( 11 ) with a bottom wall ( 12 ), two side walls ( 13 A, 13 B) rising from the bottom wall ( 12 ) and a ceiling wall ( 15 ) facing the bottom wall ( 12 ). The rectangular tube ( 11 ) includes a terminal insertion opening ( 17 ) on one end, and a tab (T) is insertable therein. A resilient contact piece ( 21 ) is arranged along the bottom wall ( 12 ) inside the rectangular tube ( 11 ). Two protection walls ( 31 A, 31 B) extend respectively from the side walls ( 13 A, 13 B) to close the terminal insertion opening ( 17 ), leaving a clearance for entrance of the tab (T) between the ceiling wall ( 15 ) and the protection walls. The protection walls ( 31 A, 31 B) have facing edges ( 35 A, 35 B) facing the mating protection walls ( 31 B, 31 A), and the facing edges ( 35 A, 35 B) extend obliquely with respect to a line (L) perpendicular to the bottom wall ( 12 ).
1. A terminal fitting to be connected to a mating terminal fitting with a tab, comprising:
a rectangular tube composed of a bottom wall, first and second side walls rising from the bottom wall and spaced apart in a width direction of the rectangular tube, and a ceiling wall extending between the first and second side walls and facing the bottom wall, the rectangular tube including an opening on one end, the tab being insertable into the opening;
a resilient contact piece in the form of a leaf spring arranged along the bottom wall inside the rectangular tube;
a first protection walls extending from the first side wall towards the second side wall and having a first facing edge spaced from the first side wall, the first facing edge including at least one oblique portion inclined obliquely with respect to the first and second side walls; and
a second protection wall extending from the second side wall towards the first side wall, and having a second facing edge spaced from the second side wall, the second facing edge including at least one oblique portion inclined obliquely to the second side wall and parallel to the oblique portion of the first facing edge, wherein
the at least one oblique portion of the first facing edge and the at least one oblique portion of the second facing edge at least partially overlap each other in the width direction of the rectangular tube.
2. The terminal fitting of claim 1 , wherein the facing edge is inclined obliquely over an entire length thereof.
3. The terminal fitting of claim 1 , wherein a part of the facing edge toward the ceiling wall and a remaining part toward the bottom wall are inclined in opposite directions with respect to a line perpendicular to the bottom wall.
