Claim:
A plug comprising: an inner pin extending between a first inner end and a second inner end about a longitudinal axis, wherein the inner pin includes a first inner end contact portion at the first inner end; an outer pin extending between a first outer end and a second outer end about the longitudinal axis and about a portion of the inner pin, wherein the outer pin includes a first outer end contact portion at the first outer end; a layer of nonconductive material disposed at least between the outer pin and the portion of the inner pin; a more inner pin extending between a first more inner end and a second more inner end about the longitudinal axis; and an innermost pin extending between a first innermost end and a second innermost end about the longitudinal axis, wherein: the first outer end contact portion extends a first distance beyond the first inner end contact portion in a first direction parallel to the longitudinal axis; the first inner end contact portion faces away from the longitudinal axis; the first outer end contact portion faces towards the longitudinal axis; the inner pin extends about a portion of the more inner pin; the more inner pin includes a first more inner end contact portion at the first more inner end; the first outer end contact portion extends a second distance beyond the first more inner end contact portion in the first direction parallel to the longitudinal axis; the more inner pin extends about a portion of the innermost pin; the innermost pin includes a first innermost end contact portion at the first innermost end; and the first outer end contact portion extends a third distance beyond the first innermost end contact portion in the first direction parallel to the longitudinal axis.
