Patent ID: 8235756

Claim:
A plug comprising: an innermost pin extending between a first innermost end and a second innermost end about a longitudinal axis; a mid-inner pin extending between a first mid-inner end and a second mid-inner end about the longitudinal axis and about a portion of the innermost pin; an inner pin extending between a first inner end and a second inner end about the longitudinal axis and about a portion of the mid-inner pin; and 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 first outer end of the outer pin extends a first distance beyond the first inner end of the inner pin in a first direction parallel to the longitudinal axis; the first outer end of the outer pin extends a second distance beyond the first mid-inner end of the mid-inner pin in the first direction parallel to the longitudinal axis; the first outer end of the outer pin extends a third distance beyond the first innermost end of the innermost pin in the first direction parallel to the longitudinal axis; and the shortest distance between the first outer end of the outer pin and the longitudinal axis is one of equal to and less than the shortest distance between the first inner end of the inner pin and the longitudinal axis.
