Abstract

The invention relates to an electric plug connector for electrically connecting at least one first and one second thermocouple conductor, comprising at least one electrically conductive first and second contacting means, wherein the first thermocouple conductor is to be connected to the first contacting means, and the second thermocouple conductor is to be connected to the second contacting means, at least one first electrical temperature sensor, which is provided with a temperature sensing region and with at least one first and one second electrical contact, wherein at least one part of the temperature sensing region of the first temperature sensor is directly attached to the first contacting means by a joint.

Claims

1. An electric plug connector for electrically connecting at least one first and one second thermocouple conductor (7, 8), comprising

at least one electrically conductive first and second contacting means (1, 2), wherein the first thermocouple conductor (7) is to be connected to the first contacting means (1), and the second thermocouple conductor (8) is to be connected to the second contacting means (2),

at least one first electrical temperature sensor (10), which is provided with a temperature sensing region (11) and with at least one first and one second electrical contact (12, 13), wherein at least one part of the temperature sensing region (11) of the first temperature sensor (10) is attached to the first contacting means (1) by a joint (27).

2. The electric plug connector as claimed in claim 1, wherein at least one part of the temperature sensing region (11) of the first temperature sensor (10) is attached to the second contacting means (2) by a joint, and/or the temperature sensing region (11) of the at least first temperature sensor (10) is attached to the first and/or second contacting means (1, 2) in a heat-conducting manner and/or is galvanically isolated from the first and/or second contacting means (1, 2).

3. The electric plug connector as claimed in claim 1, wherein at least one part of the temperature sensing region (15) of a second temperature sensor (14) is attached to the second contacting means (2) by a joint.

4. The electric plug connector as claimed in claim 1, wherein the first thermocouple conductor (7) is electrically connected to the first contacting means (1), and the second thermocouple conductor (8) is electrically connected to the second contacting means (2).

5. The electric plug connector as claimed in claim 1, wherein the first electrical contact (12) of the first temperature sensor (10) is electrically connected to an electrically conductive third contacting means (3).

6. The electric plug connector as claimed in claim 5, wherein the second electrical contact (12) of the first temperature sensor (10) is electrically connected to the first contacting means (1).

7. The electric plug connector as claimed in claim 5, wherein the second electrical contact (13) of the first temperature sensor (10) is electrically connected to an electrically conductive fourth contacting means (4).
