Abstract

A terminal fitting ( 10, 120, 210, 230 ) has a connecting portion ( 11, 121, 211 ) to be connected with a mating terminal and a wire barrel ( 12, 126, 212 ) to be crimped into connection with an end portion of a wire ( 20, 110, 220 ). A restriction ( 18, 152, 218 A, 231 ) is between the connecting portion ( 11, 121, 211 ) than the wire barrel ( 12, 126, 212 ) and faces a placing surface of a bottom plate ( 16, 123, 216 ) where the end portion of the wire ( 20, 110, 220 ) is to be placed for restricting an upward movement of the end portion of the wire ( 20, 110, 220 ).

Claims (32)

1. A terminal fitting, comprising:

a connecting portion to be connected with a mating terminal;

a wire barrel to be crimped into connection with an end portion of a wire;

a base plate extending between the connecting portion and the wire barrel;

first and second side walls projecting up from opposite first and second lateral sides of the base plate;

at least one restriction arranged between the connecting portion and the wire barrel and substantially facing a placing surface of the base plate, where the end portion of the wire is to be placed the restriction being bent to extend from at least the first side wall toward the second side wall and spaced from the base plate for restricting a movement of the end portion of the wire in a direction substantially away from the base plate; and

a front stop extending from the restriction substantially to the base plate and being at a side of the restriction closer to the connecting portion so that the front stop contacts a longitudinal front end of the end of the wire.

2. The terminal fitting of claim 1 , wherein the front stop is unitary with the restriction.

3. The terminal fitting of claim 1 , wherein at least one reinforcement is formed between the connecting portion and the wire barrel for increasing rigidity of the base plate.

4. The terminal fitting of claim 3 , wherein the reinforcement is a rib that extends in forward and backward directions (FBD) along at least part of the connecting portion and projects unitarily from the base plate.

5. The terminal fitting of claim 4 , wherein the reinforcements are substantially L-shaped and extend inwardly from ends of the side walls with the facing surfaces thereof held in contact.

6. A terminal fitting for a wire comprising:

a connecting portion to be connected with a mating terminal;

a wire barrel to be crimped into connection with an end portion of a wire;

a base plate extending between the connecting portion and the wire barrel;

first and second side walls projecting up from opposite first and second lateral sides of the base plate;

a restriction bulging out from the base plate centrally between the side walls and between the connection portion and the wire barrel, the restriction being joined unitarily to the base plate at least at two opposed sides and being deformed from the base plate into an arched shape with at least one open end in a forward and backward direction; wherein

the restriction is dimensioned to prevent the wire from being bent in an upward direction away from the base plate.

7. The terminal fitting of claim 6 , wherein the front end of the restriction is closed to define a front stop.

8. A terminal fitting, comprising:

a connecting portion for connecting with a mating terminal;

a wire barrel configured to be crimped into connection with an end portion of a wire;

a base plate extending between the connecting portion and the wire barrel;

first and second spaced apart side walls projecting up from opposite first and second lateral sides of the base plate;

at least one restriction between the connecting portion and the wire barrel and extending unitarily from a location on the first side wall spaced from the base plate and projecting toward the second side wall, at least a portion of the restriction being spaced from the base plate; and

a front stop between the connecting portion and the wire barrel and configured for contacting and positioning a longitudinal front end of the end of the wire; whereby

the end portion of the wire is positioned between the restriction and the base plate for restricting movement of the end portion of the wire away from the base plate.

9. The terminal fitting of claim 8 , wherein the restriction is a first restriction and the terminal fitting further comprising a second restriction extending unitarily from a location on the second side wall spaced from the base plate and projecting toward the first side wall.

10. The terminal fitting of claim 8 , wherein the front stop is unitary with the restriction.

11. The terminal fitting of claim 8 , wherein the front stop is between the connecting portion and the restriction.

12. The terminal fitting of claim 8 , wherein the restriction bulges unitarily out from the base plate.

13. The terminal fitting of claim 12 , further comprising a front stops joined unitarily to a side of the restriction facing the connecting portion and configured for contacting a longitudinal front end of the end of the wire, the front stop and the restriction defining a dome-shaped bulge on the base plate.
