Abstract
A terminal fitting (10) includes a tubular main portion (11) into which a mating male tab (91) is insertable from the front. A resilient contact piece (22) which is to be resiliently held in contact with the male tab (91) is resiliently deformably formed in the main portion (11), and a contact portion (32) which receives the male tab (91) is fixedly formed at a position facing the resilient contact piece (22). The contact portion (32) includes a folded part formed by folding a backward extending part of an outer wall of the main portion (11) inwardly and forwardly. A curved R surface (41) is formed on the outer surface of the folded part of the contact portion (32).
Claims8
A terminal fitting, comprising:
- a wire barrel configured for connection to a wire;
- a tubular main portion having a rear end facing the wire barrel and a front end opposite the rear end;
- a resiliently deformable contact piece in the main portion;
- and
- a fixed contact portion in the main portion facing the resilient contact piece, the contact portion including a folded part folded in and forward from an end of an outer wall of the main portion at the rear end of the main portion and a curved R surface formed on an outer surface of the folded part of the contact portion and extending rearward of the main portion to prevent the main portion from being caught when the terminal fitting is pulled reawardly.
A connector, comprising:
- a housing formed with at least one cavity into which the terminal fitting is to be inserted from behind, and an accommodation recess at a rear part of the housing;
- the terminal fitting accommodated in the cavity (63), the terminal fitting including a tubular main portion, a resiliently deformable contact piece in the main portion, and a fixed contact portion in the main portion facing the resilient contact piece, the contact portion including a folded part folded in and forward from an outer wall of the main portion and a curved R surface formed on the outer surface of the folded part of the contact portion;
- a seal accommodated in the accommodation recess, the seal having at least one wire insertion hole at a position corresponding to the cavity, the wire insertion hole having an inner peripheral surface for sealing contact with a wire connected to the terminal fitting, wherein
- the R surface slides on the inner peripheral surface of the wire insertion hole of the seal when the terminal fitting inserted in the cavity is pulled out backward.
