Abstract
A temperature sensor detects temperatures of at least two distribution lines and includes a temperature detection unit and a protection member that covers the temperature detection unit. The protection member is provided with a first abutting surface that has a concave shape corresponding to an outer shape of a first distribution line and is in contact with the first distribution line and a second abutting surface that has a concave shape corresponding to an outer shape of a second distribution line and is in contact with the second distribution line.
Claims12
A temperature sensor that detects temperatures of at least two distribution lines, the temperature sensor comprising:
- a temperature detection unit;
- and
- a protection member that covers the temperature detection unit,
- wherein the protection member is provided with a first abutting surface that has a concave shape corresponding to an outer shape of a first distribution line and is in contact with the first distribution line and a second abutting surface that has a concave shape corresponding to an outer shape of a second distribution line and is in contact with the second distribution line,
- wherein the first abutting surface is provided on a first surface of the protection member,
- wherein the second abutting surface is provided on a second surface of the protection member on a side opposite to the first surface, and
- wherein, when a virtual line that divides the first abutting surface and the second abutting surface into two halves in a width direction in a transverse section of the protection member is defined as a reference line, the temperature detection unit is arranged at a position offset from the reference line by a predetermined distance in the width direction of the protection member.
A temperature sensor that detects temperatures of at least two distribution lines, the temperature sensor comprising:
- a temperature detection unit;
- a protection member that covers the temperature detection unit;
- and
- a lead wire for taking out signals from the temperature detection unit, a part of the lead wire being covered with the protection member and another part thereof being led out to an outside of the protection member,
- wherein the protection member is provided with a first abutting surface that has a concave shape corresponding to an outer shape of a first distribution line and is in contact with the first distribution line and a second abutting surface that has a concave shape corresponding to an outer shape of a second distribution line and is in contact with the second distribution line, and
- wherein a lead-out direction of the lead wire with respect to the protection member is the same as a longitudinal direction of the first abutting surface and the second abutting surface.
A temperature sensor that detects temperatures of at least two distribution lines, the temperature sensor comprising:
- a temperature detection unit;
- a protection member that covers the temperature detection unit;
- and
- a lead wire for taking out signals from the temperature detection unit, a part of the lead wire being covered with the protection member and another part thereof being led out to an outside of the protection member,
- wherein the protection member is provided with a first abutting surface that has a concave shape corresponding to an outer shape of a first distribution line and is in contact with the first distribution line and a second abutting surface that has a concave shape corresponding to an outer shape of a second distribution line and is in contact with the second distribution line, and
- wherein a lead-out direction of the lead wire with respect to the protection member is different from a longitudinal direction of the first abutting surface and the second abutting surface.
A power distribution component having two or more distribution lines and a temperature sensor that detects temperatures of the distribution lines, the temperature sensor comprising:
- a temperature detection unit;
- and
- a protection member that covers the temperature detection unit,
- wherein the protection member is provided with a first abutting surface that has a concave shape corresponding to an outer shape of a first distribution line and is in contact with the first distribution line and a second abutting surface that has a concave shape corresponding to an outer shape of a second distribution line and is in contact with the second distribution line.
