Abstract

Provided is a terminal fitting and a connector with which the amount of insertion of the terminal fitting into a housing can be easily controlled. A terminal fitting includes: a tubular connection portion ( 41 ); a locking protrusion ( 51 ) that is provided so as to protrude from an outer circumferential surface side of the tubular connection portion ( 41 ), and is configured to be locked to a groove ( 66 ) provided in a housing ( 60 ); and a contact-stopper protrusion ( 55 ) that is provided on the outer circumferential surface side of the tubular connection portion ( 41 ) so as to protrude from mating edges ( 49 ) that abut against each other in a circumferential direction thereof in the tubular connection portion ( 41 ), and is configured to come into contact with the housing ( 60 ) and stop in place.

Claims (18)

1. A terminal fitting comprising:

a tubular connection portion;

a locking protrusion that is provided so as to protrude from an outer circumferential surface side of the tubular connection portion, and is configured to be locked to a groove provided in a housing; and

a contact-stopper protrusion that is provided on the outer circumferential surface side of the tubular connection portion so as to protrude from mating edges that abut against each other in a circumferential direction thereof in the tubular connection portion, and is configured to come into contact with the housing and stop in place,

wherein, in a state where the tubular connection portion is inserted to a regular position in the housing, a surface of the contact-stopper protrusion opposite to a surface thereof that comes into contact with the housing and stops in place is not locked to the housing,

the mating edges each having at least one of a protruding portion and a recessed portion are closed with the protruding portion and the recessed portion engaging with each other, and

the contact-stopper protrusion protrudes from the protruding portion.

2. The terminal fitting according to claim 1 , further comprising

a lead portion configured to be connected to a circuit board,

wherein the lead portion extends to one side on the outer circumferential surface side of the tubular connection portion, and

the contact-stopper protrusion is provided on the one side of the tubular connection portion.

3. A connector comprising:

the terminal fitting according to claim 1 ; and

the housing into which the terminal fitting is to be inserted,

wherein the housing has a contact-stopper groove into which the contact-stopper protrusion is to be inserted, and

the contact-stopper groove is open in an outer side of the housing.

4. The connector according to claim 3 ,

wherein the contact-stopper groove includes a hole which is open in a direction perpendicular to an axis of the tubular connection portion to expose the contact-stopper protrusion through the hole.
