Abstract
An electrical connection assembly to establish a connection between the terminal elements of electrical conductors which are fitted with terminal rings and including a thermo-deformable element configured to undergo strain as a function of the temperature of the connection assembly, such that an electrical contact between two electrical contact elements is established or interrupted. It is possible to execute detection of conditions for initiation of an electric arc or the presence of a continuous or intermittent electric arc in the connection assembly, by reference to the heat-up of the thermo-deformable element associated with the initiation or the presence of an electric arc.
Claims9
An electrical connection assembly comprising:
- a stud which is rigidly attached to a support and a thread of which projects from the support, the stud comprising a head which projects at an opposing side of the support vis-à-vis the thread, wherein the assembly is configured such that a nut which is fitted to the thread is able to clamp one or more terminal rings between the support and the nut;
- wherein at least one first electrically conductive and thermo-deformable electrical contact element is electrically connected to the stud, and is on the head of the stud vis-à-vis a second electrical contact element which is connected to an equipotential reference source;
- and
- wherein the first thermo-deformable electrical contact element is configured to be electrically isolated from the second electrical contact element in an event that a temperature thereof is lower than a predetermined threshold value, and to be electrically connected to the second electrical contact element, in an event that a temperature thereof is greater than or equal to a predetermined threshold value, or vice versa.
