A thermal sensing system includes an electrical contact, a sensing element, and at least one position sensor. The electrical contact releasably connects to a mating contact for establishing a conductive path across a mating interface. The electrical contact defines a channel therein that extends from an opening along an outer surface of the electrical contact. The sensing element is at least partially outside of the channel and is configured to move relative to the electrical contact from a first position to a second position based on a temperature increase within the channel that exceeds a designated threshold temperature. The at least one position sensor is spaced apart from the electrical contact and is configured to detect a position change of the sensing element from the first position to the second position, indicating that the temperature within the channel exceeds the designated threshold temperature.

Electrical connector comprising a detection device for detecting potential overheating, which comprises an electrically conductive element and an electrically insulating element inserted between the electrically conductive element and a low-voltage line. The electrically conductive element exerts an elastic force on the insulating element. For example, the electrically conductive element is a spring. In the event of overheating, the insulating element deforms under the pressure of the electrically conductive element and enables an electrical connection between two low-voltage lines. The overheating is detected as a consequence of the electrical design of this connection between the low-voltage lines.

A connector has a first end provided with a first interface and a second end provided with a second interface. The second interface includes a first switch unit and a second switch unit, where the second switch unit is connected to a control terminal of the first switch unit and a ground pin of the second interface, and a preset reference voltage is input into the ground pin of the second interface. In a case that the second interface is disconnected from a to-be-charged device, the first switch unit is in an off state. In a case that the second interface is connected to the to-be-charged device, the ground pin of the second interface is connected to a ground pin of the to-be-charged device, the ground pin of the second interface is grounded, and the first switch unit is in an on state.

A charging cable including a rectifier, a first connector element, and a second connector element. The first connector element is designed for connection to a vehicle-external energy source and the second connector element is designed for connection to a charging socket of a motor vehicle with an electrical traction energy accumulator. An alternating current supplied at the first connector element is convertible by the rectifier into a direct current deliverable at the second connector element. The first connector element is detachably fastened on the charging cable via an interface of the charging cable.

A conducting strip overheating power off structure, comprises a first conducting strip, a second conducting strip, and an overheating destructive member. A first limiting strip and the second limiting strip of the overheating destructive member astride the first conducting strip and the second conducting strip. The first limiting strip or/and the second limiting strip is/are provided with a limiting portion, which enables the first conducting strip and the second conducting strip to be in contact with each other and form a closed circuit. The connecting portion connects the first limiting strip to the second limiting strip, and the supporting member is disposed between the first limiting strip and the second limiting strip. Accordingly, overheating of the supporting member causes the limiting portions to no longer capable to force the first conducting strip and the second conducting strip to be in contact with each other, thus forming an open circuit.
