Claims
- 1. A composite insulator comprising:a) a rod having a shield layer and a plurality of weathersheds fastened to the rod through the shield layer; b) each of said weathersheds comprising a body molded in one piece from a rubber-like material; c) said body having a disc-like configuration and including a central hub and a skirt extending radially outwardly from said hub so as to define a slight bell shape; d) the height of the hub being more than one-half the overall height of the body; e) an aperture in said central hub having an internal face with a substantially uniform diameter along the full height of the hub; f) said skirt having an upper face and a lower face extending from said hub to an annular outer edge which is curved between said upper and lower faces; g) an annular depression formed in said lower face, spaced outwardly from said rod and around said hub; h) said annular depression defining an external face on said hub and a portion of said lower face of said skirt; i) a continuously curved, external lower edge on said hub below said skirt and spaced outwardly from said rod; j) a continuously curved upper edge on said hub above said skirt and spaced outwardly from said hub; k) the configuration of said annular depression being such that said portion of said lower face extends substantially parallel to a corresponding portion of said upper face; and l) said skirt having a substantially uniform thickness and curving downwardly and then upwardly between said hub and said annular outer edge.
- 2. A composite insulator comprising:a) a rod having a shield layer and a plurality of weathersheds fastened to the rod through the shield layer; b) each of said weathersheds comprising a body molded in one piece from a rubber-like material; c) said body having a disc-like configuration and including a central hub and a skirt extending radially outwardly from said hub so as to define a slight bell shape; d) the height of the hub being more than one-half the overall height of the body; e) an aperture in said central hub having an internal face with a substantially uniform diameter along the full height of the hub; f) said skirt having an upper face and a lower face extending from said hub to an annular outer edge which is curved between said upper and lower faces; g) an annular depression formed in said lower face, spaced outwardly from said rod and around said hub; h) said annular depression defining an external face on said hub and a portion of said lower face of said skirt; i) a continuously curved, external lower edge on said hub below said skirt and spaced outwardly from said rod; j) a continuously curved upper edge on said hub above said skirt and spaced outwardly from said hub; k) the configuration of said annular depression being such that said portion of said lower face extends substantially parallel to a corresponding portion of said upper face; and l) said skirt having a substantially uniform thickness between said hub and said annular outer edge; and m) the thickness of said hub between said external upper edge and said external lower edge being as great or greater than the thickness of said skirt.
- 3. The composite insulator of claim 2 further characterized in that:a) said skirt curves downwardly and then upwardly from said hub to said annular outer edge.
- 4. A weathershed for a composite insulator wherein said insulator includes a rod having a shield layer, said weathershed comprising:a) a body molded in one piece from a rubber-like material; b) said body having a disc-like configuration and including a central hub and a skirt extending radially outwardly from said hub; c) the height of the hub being more than one-half the overall height of the body; d) a rod receiving aperture in said central hub having an internal face with a substantially uniform diameter along the full height of the hub; e) said skirt having an upper face and a lower face extending from said hub to an annular outer edge which is curved between said upper and lower faces; and f) an annular depression formed in said lower face, spaced outwardly from said rod and around said hub; g) said annular depression defining an external face on said hub and a portion of said lower face of said skirt; h) the configuration of said annular depression being such that said portion of said lower face extends substantially parallel to a corresponding portion of said upper face; and i) said skirt having a substantially uniform thickness between said hub and said annular outer edge. j) said skirt curving downwardly and outwardly from said hub at a decreasing radius of curvature so that an inner portion of said skirt has a bell shape and the outer portion of said skirt is shaped like a flattened frustum of a cone.
