Abstract

A charging connector for charging a battery installed in a vehicle includes a housing (51) with at least one accommodating chamber (64a) for at least partly accommodating at least one terminal fitting (10), and at least one sensor (S) mounted to at least one terminal fitting (10) by a shrinking tube (20). A corresponding method and a corresponding terminal fitting (10) also are provided.

First claim

The invention claimed is:

1. A charging connector for charging a battery installed in a vehicle comprising:
a housing having an accommodating chamber;
a terminal fitting having a connecting part accommodated in the accommodating chamber and a wire connection portion rearward of the connecting part and configured to be connected to a wire;
a thermal coupling mounted in surface contact with an outer surface with the wire connection portion of the terminal fitting;
at least one sensor mounted in the thermal coupling;
a shrinking tube circumferentially surrounding the wire connection portion of the terminal fitting and the thermal coupling that has the sensor mounted therein, the shrinking tube being shrunk and holding the thermal coupling and the sensor against the wire connection portion of the terminal fitting.

2. The charging connector of claim 1 , wherein the thermal coupling comprises at least one of a sleeve, a mounting bracket, and a clamp, and wherein the thermal coupling having said sensor being at least partly arranged therein is fixed to the terminal fitting by the at least one shrinking tube.

3. The charging connector of claim 2 , wherein the thermal coupling member is made of a material having a good thermal conductivity.

4. The charging connector of claim 1 , wherein the sensor is a temperature sensor.

5. The charging connector of claim 4 , wherein the temperature sensor is selected from the group consisting of a NTC sensor, a PTC sensor or a PT sensor.
