## Abstract

A connector includes a terminal fitting connected to an end of an electric wire, a housing including a terminal accommodating chamber configured to accommodate the terminal fitting, a temperature sensor connected to an end of a detection line and configured to be attached to the terminal fitting, and a heat retaining cover. The heat retaining cover is configured to be attached to the housing such that the heat retaining cover covers a rear end portion of the housing and to retain heat inside the terminal accommodating chamber, the heat retaining cover having an electric wire guiding out portion through which the electric wire and the detection line drawn out from the terminal accommodating chamber are to be inserted.

## Claims

### Claim 1

A connector including:
a terminal fitting connected to an end of an electric wire,
a housing including a terminal accommodating chamber configured to accommodate the terminal fitting,
a temperature sensor connected to an end of a detection line and configured to be attached to the terminal fitting, and
a heat retaining cover,
wherein the heat retaining cover is configured to: be attached to the housing such that the heat retaining cover covers a rear end portion of the housing; and to retain heat inside the terminal accommodating chamber, the heat retaining cover having an electric wire guiding out portion through which the electric wire and the detection line drawn out from the terminal accommodating chamber are to be inserted.

### Claim 2 (depends on 1)

The connector according to claim 1 further including:
an electric wire seal accommodating portion and a detection line seal accommodating portion continuously provided with the terminal accommodating chamber, respectively,
an electric wire seal member including an electric wire seal hole through which the electric wire is to be inserted and configured to be attached to the electric wire seal accommodating portion, and
a detection line seal member including a detection line seal hole through which the detection line is to be inserted and configured to be attached to the detection line seal accommodating portion.

### Claim 3 (depends on 1)

The connector according to claim 1,
wherein the heat retaining cover is configured to homogenize temperature of an entirety of the terminal fitting.
