Abstract

A wire with crimped terminal is provided with a wire and a crimped terminal connected to a terminal portion of the wire. The crimped terminal is provided with a board-shaped base portion where the wire is arranged; a counterpart member connector provided at a forefront end of the base portion; a pair of core wire crimp tabs crimped to a core wire portion of the wire; and a pair of sheath crimp tabs crimped to an insulated sheath portion of the wire. The core wire crimp tabs are each provided with an inwardly-recessed contracted portion on both sides of the core wire crimp tab in an X axis direction, in an area closer to the base portion than a leading edge portion of the core wire crimp tab, the contracted portion thereby having a smaller width in the X axis direction.

Claims

1. A wire with crimped terminal comprising a wire and a crimped terminal connected to a terminal portion of the wire, wherein the crimped terminal comprises:

a board-shaped base portion having a wiring portion that faces a wiring area where the wire is arranged;

a counterpart member connector provided at a forefront end of the base portion and conductively connecting to a counterpart member; and

a core wire crimp tab provided toward a base end side of the base portion with respect to the counterpart member connector, extending from a side of the base portion in a width direction, and crimped to a core wire portion of the wire arranged on the base portion while the tab is bent inwardly toward the base portion,

wherein the core wire crimp tab is provided with an inwardly-recessed contracted portion on at least one of two sides of the core wire crimp tab in a length direction of the base portion, in an area closer to the base portion than a leading edge portion of the core wire crimp tab, the contracted portion thereby having a smaller width in the length direction than the leading edge portion, wherein the contracted portion is defined by at least one recess having an opened first end and a closed second end, and wherein a recessed direction from the opened first end towards the closed second end extends in the length direction.

2. The wire with crimped terminal according to claim 1, wherein the crimped terminal further comprises:

a sheath crimp tab provided toward the base end side of the base portion with respect to the core wire crimp tab, extending from a side of the base portion in a width direction, and crimped to an insulated sheath portion of the wire arranged on the base portion while the tab is bent inwardly toward the base portion.

3. The wire with crimped terminal according to claim 1, wherein the contracted portion is an inwardly recessed portion on both sides of the core wire crimp tab in the length direction.

4. The wire with crimped terminal according to claim 1, wherein the contracted portion is provided in a borderline area with the base portion of the core wire crimp tab.

7. The wire with crimped terminal according to claim 2, wherein

the board-shaped base portion has a lower side portion that is uniformly flat along the length direction of the base portion, and

the core wire crimp tab and the sheath crimp tab extend from the lower side of the base portion.

5. A wire harness having a plurality of wires with crimped terminals, each having a crimped terminal attached to a terminal portion of a wire, wherein the crimped terminal attached to the wire comprises:

a board-shaped base portion having a wiring portion that faces a wiring area where the wire is arranged;

a counterpart member connector provided at a forefront end of the base portion and conductively connecting to a counterpart member; and

a core wire crimp tab provided toward a base end side of the base portion with respect to the counterpart member connector, extending from a side of the base portion in a width direction, and crimped to a core wire portion of the wire arranged on the base portion while the tab is bent inwardly toward the base portion,

wherein the core wire crimp tab is provided with an inwardly-recessed contracted portion on at least one of two sides of the core wire crimp tab in a length direction of the base portion, in an area closer to the base portion than a leading edge portion of the core wire crimp tab, the contracted portion thereby having a smaller width in the length direction than the leading edge portion, wherein the contracted portion is defined by at least one recess having an opened first end and a closed second end, and wherein a recessed direction from the opened first end towards the closed second end extends in the length direction.

6. A crimped terminal attached to a terminal portion of a wire, the crimped terminal being formed with a conductive material, and comprising:

a board-shaped base portion having a wiring portion that faces a wiring area where the wire is arranged;

a counterpart member connector provided at a forefront end of the base portion and conductively connecting to a counterpart member; and

a core wire crimp tab provided toward a base end side of the base portion with respect to the counterpart member connector, extending from a side of the base portion in a width direction, and crimped to a core wire portion of the wire arranged on the base portion while the tab is bent inwardly toward the base portion,

wherein the core wire crimp tab is provided with an inwardly-recessed contracted portion on at least one of two sides of the core wire crimp tab in a length direction of the base portion, in an area closer to the base portion than a leading edge portion of the core wire crimp tab, the contracted portion thereby having a smaller width in the length direction than the leading edge portion, wherein the contracted portion is defined by at least one recess having an opened first end and a closed second end, and wherein a recessed direction from the opened first end towards the closed second end extends in the length direction.
