A protective connector includes a core assembly structure, mating pins and a mating coupling structure. The core assembly structure has circuitry mounted therein. The mating coupling structure substantially encases the core assembly structure and mates with another connector such that the mating pins of the protective connector are electrically coupled to pins of the other connector. The mating coupling structure is mechanically free-moving with respect to the core assembly structure such that forces applied to the mating coupling structure to mate the protective connector to the other connector are not applied to the circuitry within the core assembly structure.

A sealing element for sealing a housing opening in a housing, wherein the sealing element comprises at least one through-opening for the passage of an electrical cable into the housing. The sealing element is formed of a first subcomponent and a second subcomponent, the first subcomponent and the second subcomponent having a different hardness and the two subcomponents are made of silicone.
