A novel protective cap or elbow connector comprises a semi conductive insert which includes an additional volume of air which surrounds energized portions of the elbow connector or protective cap beyond what is necessary to accommodate a female bushing. During separation of the elbow connector or protective cap from the female bushing, the semiconductive insert stretches, which increases the volume of the interior space between the elbow connector or protective cap and the female bushing. Because the additional volume of air is provided, the reduction in pressure during separation is lessened, so that the dielectric strength of the air surrounding energized portions of the elbow connector or protective cap is maintained at a higher level. The increased dielectric strength of the air significantly reduces the possibility of a flashover occurring during separation of the elbow connector or protective cap from the female bushing.

[ What is claimed is:] [23.] An electrical connector comprising:a first member which includes:an opening that is closed at a first end and which receives a second member through a second end of the opening;a first electrical contact within the opening for making electrical contact with a second electrical contact of the second member; anda first retaining means within the opening which contacts a second retaining means on the second member to retain the second member in the first member;wherein a portion of the opening between the first end and the first retaining means is substantially cylindrical so as to create a volume that provides a clearance between the first member and the second member within the opening.
