High-density connector

An apparatus, comprising:

• (a) an hourglass-shaped protrusion, the hourglass-shaped protrusion being sized and configured to be securely received within an hourglass-shaped cavity of a female connector, the hourglass-shaped protrusion including:
• (i) a first portion,
• (ii) a second portion, and
• (iii) a third portion positioned between the first and second portions, the third portion being narrower than each of the first and second portions;
• and
• (b) a plurality of electrically-conductive sockets positioned on the hourglass-shaped protrusion, at least one socket of the plurality of electrically-conductive sockets being positioned solely on the third portion, each socket of the plurality of electrically-conductive sockets being configured to electrically engage a respective electrically-conductive pin positioned within the hourglass-shaped cavity of the female connector when the hourglass-shaped protrusion is received within the hourglass-shaped cavity.
