PROTECTIVE CAP FOR A TERMINAL CONNECTION OF A BATTERY
A protective cap for a terminal connection of a battery, a motor vehicle battery, and a battery cable are provided. The protective cap includes a first layer of a non-conductive layer material and a second layer superimposed on the first layer. The first layer and the second layer surround an interior space configured to receive the terminal connection in a shell-shaped manner. The first layer faces the terminal connection and consists of a material with a first modulus of elasticity E 1, and the second layer faces away from the terminal connection and consists of a material with a second modulus of elasticity E 2, wherein E 1< E 2.
