Abstract

A wiring component with physical quantity sensor is provided with a plurality of electric wires, a physical quantity sensor for detecting a physical quantity of the plurality of electric wires, an electric wire holding member including an intervening portion interposed between the plurality of electric wires, and a holder holding the physical quantity sensor. The electric wire holding member includes a protrusion protruding from the intervening portion in a direction perpendicular to an arrangement direction of the plurality of electric wires, and aligning the holder in longitudinal directions of the plurality of electric wires by the protrusion. The holder includes an electric wire engaging portion being engaged with at least one of the plurality of electric wires.

First claim

The invention claimed is:

1. A wiring component with physical quantity sensor, comprising:
a plurality of electric wires;
a physical quantity sensor for detecting a physical quantity of the plurality of electric wires;
an electric wire holding member comprising an intervening portion interposed between the plurality of electric wires; and
a holder holding the physical quantity sensor,
wherein the electric wire holding member comprises a protrusion protruding from the intervening portion in a direction perpendicular to an arrangement direction of the plurality of electric wires, and aligning the holder in longitudinal directions of the plurality of electric wires by the protrusion, and
wherein the holder comprises an electric wire engaging portion being engaged with at least one of the plurality of electric wires,
wherein the physical quantity sensor comprises a signal wire configured to transmit a physical quantity detection signal and the signal wire is inserted into a notch provided at the protrusion,
wherein the wiring component with the physical quantity sensor further comprises a plug member closing at least a part of the notch, and
wherein all along its length, the plug member contacts the signal wire along a longitudinal axis of the notch.

2. The wiring component with physical quantity sensor according to claim 1 , further comprising: a resin mold member covering the holder together with the plurality of electric wires.

3. The wiring component with physical quantity sensor according to claim 1 ,
wherein the holder comprises a plurality of the electric wire engaging portions respectively being engaged with a first electric wire and a second electric wire of the plurality of electric wires.

4. The wiring component with physical quantity sensor according to claim 1 , wherein the electric wire holding member, the holder, and the plug member are mechanically separate components.

5. The wiring component with physical quantity sensor according to claim 1 , wherein all along its length, the plug member aligns the signal wire along a longitudinal axis of the notch.

6. The wiring component with physical quantity sensor according to claim 2 ,
wherein the electric wire holding member comprises the protrusions at a plurality of positions that sandwich the holder in the longitudinal directions of the plurality of electric wires, and
wherein the resin mold member is provided between the plurality of protrusions.

7. The wiring component with physical quantity sensor according to claim 3 , wherein the plurality of electric wire engaging portions sandwich the first electric wire and the second electric wire in the arrangement direction of the plurality of electric wires.

8. The wiring component with physical quantity sensor according to claim 7 ,
wherein a distance between an opposite side end opposite to the second electric wire in a cross-section perpendicular to a longitudinal direction of the first electric wire and an opposite side end opposite to the first electric wire in a cross-section perpendicular to a longitudinal direction of the second electric wire is wider than a distance between tip ends of the plurality of electric wire engaging portions of the holder.

9. A wiring component with physical quantity sensor, comprising: a plurality of electric wires; a physical quantity sensor for detecting a physical quantity of the plurality of electric wires; an electric wire holding member comprising an intervening portion interposed between the plurality of electric wires; and a holder holding the physical quantity sensor, wherein the electric wire holding member comprises a protrusion protruding from the intervening portion in a direction perpendicular to an arrangement direction of the plurality of electric wires, and aligning the holder in longitudinal directions of the plurality of electric wires by the protrusion, and wherein the holder comprises an electric wire engaging portion being engaged with at least one of the plurality of electric wires, and wherein the physical quantity sensor comprises a signal wire configured to transmit a physical quantity detection signal and the signal wire is inserted into a notch provided at the protrusion, and wherein the wiring component with physical quantity sensor further comprises a plug member closing at least a part of the notch, and wherein the plug member comprises a plurality of engaging portions being engaged with the protrusion and the holder.
