Abstract

A terminal fitting includes a soldering portion ( 11 ) to which a conductor ( 91 ) of a wire ( 90 ) is to be soldered, solid solder ( 60 ) for soldering the conductor ( 91 ) to the soldering portion ( 11 ) in a solid state, and a holding portion ( 20 ) that holds the solid solder ( 60 ) until the solid solder ( 60 ) is melted and the conductor ( 91 ) is soldered. The conductor ( 91 ) is connected to the soldering portion ( 11 ) by melting the solid solder ( 60 ) held in the holding portion ( 20 ).

First claim

What is claimed is:

1. A terminal fitting, comprising:
a bottom plate extending in forward and backward directions;
a terminal connecting portion formed on a forward end of the bottom plate and to be connected to a mating terminal fitting;
a wire connecting portion formed on the bottom plate rearward of the terminal connecting portion and coupled to the terminal connecting portion by a coupling;
solid solder extending along the bottom plate from the wire connecting portion to a position forward of the wire connecting portion;
at least one holding portion including at least one holding piece projecting from a side edge of the bottom plate at a position forward of the wire connecting portion and aligned with areas of the solid solder forward of the wire connecting portion, the at least one holding piece being crimped to hold the solid solder on the bottom plate, wherein a conductor of a wire can be placed on the solid solder at a position so that a front end of the conductor is rearward of the holding piece and can be soldered to the solder on the wire connecting portion.

2. The terminal fitting of claim 1 , wherein the at least one holding piece comes into contact with the solid solder in a direction intersecting an extending direction of the wire.

3. The terminal fitting of claim 2 , wherein the at least one holding piece defines a step that limits a maximum forward positioning of the conductor on the solid solder.

4. The terminal fitting of claim 2 , wherein the at least one holding piece is tapered toward its projecting end to have a smaller width in a front-back direction.

5. The terminal fitting of claim 2 , wherein the at least one holding piece comprises plural holding pieces having parts to be overlapped in a width direction.

6. The terminal fitting of claim 1 , wherein the holding portion resiliently holds the solid solder.

7. The terminal fitting of claim 1 , wherein the soldering portion is wider than the bottom plate.

8. The terminal fitting of claim 1 , wherein the bottom plate comprises a curved solder attaching surface that at least partly encloses the solid solder.

9. A terminated wire assembly, comprising:
a terminal fitting having opposite front and rear ends, a bottom plate extending from the rear end toward the front end, a wire connecting portion formed on the bottom plate adjacent to the rear end and a holding portion forward of the wire connecting portion;
a solid solder extending from the wire connecting portion to the holding portion and being fixed on the terminal fitting by a crimping of the holding portion; and
a wire with a conductor positioned on the solid solder at a position rearward of the holding portion, wherein:
the solid solder is melted so that the conductor of the wire is soldered to the soldering portion.

10. The terminated wire of claim 9 , wherein the holding portion comes into contact with the solid solder in a direction intersecting an extending direction of the wire.

11. The terminated wire of claim 10 , wherein the holding portion has at least one holding piece that defines a step that limits a maximum forward positioning the conductor on the solid solder.

12. The terminated wire of claim 11 , wherein the at least one holding piece is tapered toward its projecting end to have a smaller width in a front-back direction.

13. The terminated wire of claim 11 , wherein the at least one holding piece comprises plural holding pieces having parts to be overlapped in the width direction.

14. The terminated wire of claim 9 , wherein the holding portion resiliently holds the solid solder.

15. The terminate wire of claim 9 , wherein the solid solder is wider than the bottom plate.
