Abstract

A connector includes a terminal, a connector housing, a temperature sensor, and a holder. The connector housing houses the terminal. The temperature sensor defines the terminal or an electric wire connected to the terminal as a temperature detection target, and detects temperature of the temperature detection target. The holder houses and holds the terminal, the electric wire, and the temperature sensor. The holder includes at least one first pressing portion and a second pressing portion. The first pressing portion projects toward the housed temperature sensor, and presses and pushes the temperature sensor to the temperature detection target. The second pressing portion presses and pushes the housed temperature detection target to the temperature sensor.

Claims (52)

1. A connector comprising:

a terminal;

a connector housing that houses the terminal;

a temperature sensor that detects temperature of a temperature detection target, the temperature detection target being the terminal or an electric wire connected to the terminal; and

a holder that houses and holds the terminal, the electric wire, and the temperature sensor, wherein

the holder includes at least one first pressing portion that projects toward the housed temperature sensor, and presses and pushes the temperature sensor to the temperature detection target, a second pressing portion that presses and pushes the housed temperature detection target to the temperature sensor, and a pair of projecting portions that projects toward the housed temperature sensor and sandwiches the housed temperature sensor in a first direction, the first direction intersects with a second direction in which the first pressing portion presses the temperature sensor, and the first direction is along a direction orthogonal to an axis direction of the housed electric wire, and the first pressing portion and the pair of projecting portions abut the housed temperature sensor and form an air layer between the housed temperature sensor and a wall surface of the holder.

2. The connector according to claim 1 , wherein

the first pressing portion is formed so as to be brought into point-contact or line-contact with the temperature sensor.

3. The connector according to claim 1 , wherein

at least the one first pressing portion is disposed so as to press and push a temperature detecting portion of the temperature sensor to the temperature detection target.

4. The connector according to claim 2 , wherein

at least the one first pressing portion is disposed so as to press and push a temperature detecting portion of the temperature sensor to the temperature detection target.

5. The connector according to claim 1 , wherein

the holder includes a first holder member that includes one of the first pressing portion and the second pressing portion, and a second holder member that includes the other of the first pressing portion and the second pressing portion, and is engaged with the first holder member so as to generate pressing force of the first pressing portion to the temperature sensor and pressing force of the second pressing portion to the temperature detection target.

6. The connector according to claim 2 , wherein

7. The connector according to claim 3 , wherein

8. The connector according to claim 4 , wherein

9. The connector according to claim 5 , wherein

the holder includes a holding structure at least at two positions, the holding structures holding the first holder member and the second holder member engaged with each other in an engagement state,

each of the holding structures includes a first engagement holding portion that is provided to the first holder member, a second engagement holding portion that is provided to the second holder member and is engaged with the first engagement holding portion so as to keep the engagement state, and a flexible portion that includes one of the first engagement holding portion and the second engagement holding portion, and has flexibility of deflecting during engagement operation of the first holder member and the second holder member and eliminating deflection at completion of engagement between the first holder member and the second holder member, and

the flexible portion in each of the holding structures is, when the first engagement holding portion in the holding structure sandwiches the second engagement holding portion in the holding structure, provided to the second holder member and includes the second engagement holding portion, and is, when the second engagement holding portion in the holding structure sandwiches the first engagement holding portion in the holding structure, provided to the first holder member and includes the first engagement holding portion.

10. The connector according to claim 6 , wherein

the holder includes a holding structure at least at two positions, the holding structures holding the first holder member and the second holder member engaged with each other in an engagement state,

11. The connector according to claim 7 , wherein

the holder includes a holding structure at least at two positions, the holding structures holding the first holder member and the second holder member engaged with each other in an engagement state,

12. The connector according to claim 8 , wherein

the holder includes a holding structure at least at two positions, the holding structures holding the first holder member and the second holder member engaged with each other in an engagement state,

13. The connector according to claim 5 , wherein

when a plurality of the temperature detection targets are provided and the temperature sensor is provided for each of the temperature detection targets, the second holder member is provided for each combination of the temperature detection target and the temperature sensor.

14. The connector according to claim 9 , wherein

15. The connector according to claim 1 , wherein
