An effective grounding of electrical equipment, electrical cables, housings, and the like, is accomplished by grounding lugs that are initially formed as an integral part, for example, of a grounding sleeve of electrically conducting material that surrounds a protective cable casing of electrically conducting material in a crimping manner. The lugs are only bent out of the sleeve when needed. A grounding conductor is then secured to the lug. The grounding lugs may be incorporated in all systems that are provided for protection against surge currents or excessive voltages produced by a thunderstorm, especially in a vehicle or a craft, e.g. an aircraft. A cable connector includes a hollow support body that reaches with an inner end into the grounding sleeve to provide a backing for holding an end of the cable casing clamped between the grounding sleeve and the inner end of the support body. The outer end of the support body carries a coupling nut. A protective hose of electrically insulating material is also held in place by clamping one end thereof between the inner end of the support body and the cable casing, whereby the grounding sleeve holds the casing and the hose in place.
A cable and cable connector combination comprising an electrical cable, an electrically conducting cable casing enclosing said electrical cable, a cable connector, a device for grounding said cable casing for protecting said combination against lightning, said grounding device comprising an electrically conducting grounding sleeve electrically contacting said cable casing and said cable connector for grounding said cable casing and said cable connector, and at least one grounding lug forming an integral part of said electrically conducting grounding sleeve so that said electrically conducting grounding sleeve and said grounding lug form together a one-piece electrical conductor, said grounding lug comprising means for electrically connecting a grounding conductor to said cable casing through said one-piece electrical conductor, and wherein said cable connector comprises a hollow support body of electrically conducting material arranged inside said electrically conducting grounding sleeve, said support body having a coupling end and an internal end, surrounded by said electrically conducting cable casing which in turn is surrounded by said electrically conducting grounding sleeve to clamp said electrically conducting cable casing between said support body and said electrically conducting grounding sleeve, said combination further comprising an electrically insulating protective hose enclosing said cable and surrounded by said electrically conducting cable casing formed as an electrically conducting wire mesh webbing surrounding said protective hose.
A cable and cable connector combination comprising an electrical cable, an electrically conducting cable casing enclosing said electrical cable, a cable connector, a device for grounding said cable casing for protecting said combination against lightning, said grounding device comprising an electrically conducting grounding sleeve electrically contacting said cable casing and said cable connector for grounding said cable casing and said cable connector, and at least one grounding lug forming an integral part of said electrically conducting grounding sleeve so that said electrically conducting grounding sleeve and said grounding lug form together a one-piece electrical conductor, said grounding lug comprising means for electrically connecting a grounding conductor to said cable casing through said one-piece electrical conductor, and wherein said cable connector comprises a hollow support body of electrically conducting material arranged inside said electrically conducting grounding sleeve, said support body having a coupling end and an internal end, surrounded by said electrically conducting cable casing which in turn is surrounded by said electrically conducting grounding sleeve to clamp said electrically conducting cable casing between said support body and said electrically conducting grounding sleeve, wherein said cable connector is made of electrically conducting material and said electrically conducting cable casing is a wire mesh hose forming together with said cable connector a Faraday cage for shielding said combination.
