Abstract

A temperature detection module includes: a temperature sensor; a sensor holder for holding the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with a measurement target; and a biasing member that is attached to the sensor holder and biases the temperature sensor such that a detection surface comes into contact with a measurement target. The sensor holder includes: a base portion; and an accommodating portion that extends in the separation and contact direction from the base portion and holds the temperature sensor such that movement is possible in the separation and contact direction. The accommodating portion includes a gap that allows inclination of the temperature sensor between the accommodating portion and the temperature sensor.

First claim

The invention claimed is:

1. A temperature detection module comprising:
a temperature sensor;
a sensor holder configured to hold the temperature sensor such that movement is possible in a separation and contact direction in which the temperature sensor is separated from and brought into contact with a measurement target; and
a coil spring that is attached to the sensor holder and biases the temperature sensor such that a detection surface comes into contact with the measurement target,
wherein the sensor holder includes:
a base portion; and
an accommodating portion that extends in the separation and contact direction from the base portion and holds the temperature sensor such that movement is possible in the separation and contact direction,

the accommodating portion includes a gap that allows inclination of the temperature sensor between the accommodating portion and the temperature sensor,
the temperature sensor has at least one protrusion on an outer peripheral surface,
the accommodating portion includes:
a pair of side walls located on both sides of the temperature sensor; and
at least one stopper wall that is located on a leading end of at least one of the side walls, comes into contact with the at least one protrusion of the temperature sensor, and retains the temperature sensor in the accommodating portion, wherein

the gap is provided between the at least one of the side walls and the at least one protrusion of the temperature sensor.

2. The temperature detection module according to claim 1 , wherein
the side walls of the accommodating portion include guiding grooves that extend in the separation and contact direction,
the temperature sensor includes fitting protrusions that fit into the guiding grooves of the accommodating portion, and
the gap is also provided between the guiding grooves and the fitting protrusions.

3. The temperature detection module according to claim 2 , wherein
the guiding grooves are provided respectively in the pair of side walls,
a pair of the fitting protrusions are provided on both sides of the temperature sensor, and
a straight line connecting the pair of fitting protrusions passes through a position separated from a center of the temperature sensor.

4. The temperature detection module according to claim 2 , wherein
deformation allowance grooves configured to allow deformation are provided separately from the guiding grooves on portions of the side walls of the accommodating portion, in order to improve conformability to the inclination of the temperature sensor.
