Plug connector part having temperature sensors
In an embodiment, the present invention provides a plug connector part for connection to a mating plug connector part, including a plurality of electrical contact elements for carrying an electrical current and establishing electrical contact with contact elements of a mating plug connector part, the plurality of electrical contact elements including a plurality of temperature sensors, each of which is arranged on one associated contact element, respectively, of the plurality of contact elements, to detect a change in a temperature of the associated contact element, the temperature sensors being connected to a common sensor line.
1. A plug connector part for connection to a mating plug connector part, comprising:
a plurality of electrical contact elements configured to carry an electrical current and to establish electrical contact with contact elements of a mating plug connector part, the plurality of electrical contact elements including a plurality of temperature sensors, each of which is arranged on one associated contact element respectively of the plurality of contact elements, to detect a change in a temperature of the associated contact element, the temperature sensors being connected to a common sensor line,
wherein the temperature sensors are electrically interconnected in a series circuit by line portions of the sensor line, each of the line portions directly connecting two of the temperature sensors with each other.
2. The plug connector part according to claim 1 , wherein the temperature sensors comprise temperature-dependent resistors.
3. The plug connector part according to claim 2 , wherein an electrical resistance of each temperatures sensor increases as the temperature increases.
4. The plug connector part according to claim 1 , wherein the temperature sensors have a non-linear temperature characteristic.
5. The plug connector part according to claim 1 , further comprising an evaluation device to which the sensor line is connected and which is configured to evaluate a sensor signal provided via the sensor line.
6. The plug connector part according to claim 5 , wherein the evaluation device is configured to identify, on the basis of the sensor signal, that at least one of the contact elements has exceeded a temperature threshold value.
7. The plug connector part according to claim 1 , wherein the temperature sensors are each arranged on an electrically conductive shank of the respective associated contact elements.
8. The plug connector part according to claim 7 , wherein the shank is arranged at an end of the respective associated contact element that is remote from a head of the respective associated contact element, the head of the contact element being configured to be plugged into a further contact element of a mating plug connector part.
9. The plug connector part according to claim 1 , wherein the temperature sensors are crimped to associated contact elements by a crimp sleeve.
