Abstract
A male contact assembly for high voltage switching applications includes a male contact with an electrically insulative member arranged concentrically with the contact and extending longitudinally therefrom. The insulative member has a hollow interior adjacent the contact and a solid electrically conductive element in such hollow interior is in electrically conductive connection with the contact. Arc-quenching material overlies the insulative member and, on fracturing of such material, the insulative member isolates the electrically conductive member therein and the contact from electrical arcing.
Claims5
A male contact assembly comprising:
- a. an elongate male contact of electrically conductive material;
- b. an electrically insulative member secured to said male contact and extending longitudinally therefrom, said insulative member defining a hollow interior extending at least partly therewith;
- c. a solid electrically conductive element in said insulative member interior and connected to said male contact for electrically longitudinally extending said male contact;
- and
- d. a longitudinally extending layer overlying said insulative member and comprised of material generating arc-extinguishing gases upon exposure to electrical arcing, the longitudinal extent of said layer being greater than the longitudinal extent of said element in said insulative member.
A male contact assembly comprising:
- a. an elongate male contact of electrically conductive material;
- b. an electrically insulative member secured to said male contact and extending longitudinally therefrom, said insulative member defining a hollow interior extending at least partly therewith;
- c. a solid electrically conductive element in said insulative member interior and connected to said male contact for electrically longitudinally extending said male contact;
- and
- d. a layer overlying said insulative member and comprised of material generating arc-extinguishing gases upon exposure to electrical arcing, wherein said insulative member comprises a hollow tube extending substantially the full longitudinal extent of said overlying layer, and wherein said tube further contains therein material generating arc-extinguishing gases upon exposure to electrical arcing.
A male contact assembly comprising:
- an elongate male contact of electrically conductive material;
- an electrically insulative member secured to said male contact and extending longitudinally therefrom, said insulative member defining a hollow interior extending at least partly therewith;
- a solid electrically conductive element in said insulative member interior and connected to said male contact for electrically longitudinally extending said male contact;
- the longitudinal extent of said element being less that the longitudinal extent of said insulative member, and a layer overlying said insulative member and comprised of material generating arc-extinguishing gases upon exposure to electrical arcing.
