Abstract

A wiring component with temperature sensor includes an electric wire, a temperature sensor including a detection unit configured to detect temperature of the electric wire and a plurality of lead wires, and a plurality of connector pins respectively connected to the plurality of lead wires. The electric wire, the temperature sensor and the plurality of connector pins are collectively held by a holder made of a resin. The holder includes a connector housing member configured to hold the plurality of connector pins and a molded resin member covering a portion of the connector housing member.

First claim

The invention claimed is:

1. A wiring component with temperature sensor, comprising:
an electric wire as a temperature measurement target object;
a temperature sensor comprising a detection unit configured to detect temperature of the electric wire and a plurality of lead wires; and
a plurality of connector pins respectively connected to the plurality of lead wires,
wherein the electric wire, the temperature sensor and the plurality of connector pins are collectively held by a holder comprising a resin, and
wherein the holder comprises a connector housing member configured to hold the plurality of connector pins and a molded resin member covering a portion of the connector housing member,
wherein the holder comprises an electric wire holding member configured to hold the electric wire and a sensor holding member configured to hold the temperature sensor, and wherein the electric wire holding member and the sensor holding member, together with the connector housing member, are integrated by the molded resin member, and
wherein the temperature sensor does not directly contact the sensor mold resin member.

2. The wiring component with temperature sensor according to claim 1 ,
wherein a housing hole configured to house the sensor holding member is formed on the electric wire holding member, and
wherein the electric wire holding member and the sensor holding member are integrated in a state in which the sensor holding member is housed in the housing hole.

3. The wiring component with temperature sensor according to claim 2 ,
wherein a plurality of the electric wires are held by the electric wire holding member so as to be in parallel and at a distance from each other along a predetermined arrangement direction, and
wherein the housing hole is formed between the electric wires when the plurality of the electric wires are viewed in a direction that is perpendicular to the arrangement direction and a longitudinal direction of the electric wires.

4. The wiring component with temperature sensor according to claim 1 , wherein the electric wire is not connected to the plurality of lead wires.

5. The wiring component with temperature sensor according to claim 1 , wherein the connector housing member includes a cylindrical portion and a longitudinal portion of each of the plurality of connector pins is accommodated in the cylindrical portion.

6. The wiring component with temperature sensor according to claim 1 , wherein the connector housing protrudes from the molded resin member in a direction intersecting a longitudinal direction of the electric wire.

7. The wiring component with temperature sensor according to claim 1 , wherein each of the plurality of connector pins protrudes in a direction intersecting a longitudinal direction of the electric wire.

8. The wiring component with temperature sensor according to claim 1 , wherein the electric wire that is the temperature measurement target object extends into and out of the holder, and wherein both ends of the electric wire are exposed from the holder, respectively.

9. The wiring component with temperature sensor according to claim 1 , wherein the electric wire holding member, the sensor holding member, and the connector housing member are formed separately and integrated by the molded resin member.

10. The wiring component with temperature sensor according to claim 1 , wherein the temperature sensor does not directly contact the electric wire.

11. The wiring component with temperature sensor according to claim 1 , wherein the temperature sensor is separated from the electric wire by a portion of the electric wire holding member.

12. The wiring component with temperature sensor according to claim 1 , wherein the temperature sensor is separated from the electric wire by a portion of the sensor holding member.

13. The wiring component with temperature sensor according to claim 1 , wherein the temperature sensor is separated from the electric wire by a portion of the electric wire holding member and a portion of the sensor holding member.

14. The wiring component with temperature sensor according to claim 1 , wherein the connector housing member is mechanically separate from the holder and is disposed orthogonally with respect to a longitudinal direction of the electric wire.
