The electrical connector assembly further includes a male connector that includes a male connector housing having an hourglass-shaped protrusion dimensioned to be inserted into and fit tightly within the cavity and a second array of electrically-conductive sockets, which are contained within the protrusion and are dimensioned and aligned so that upon insertion of the protrusion into the cavity, each of the pins is introduced into and makes electrical contact with a respective one of the sockets. ## Claims ### Claim 1 An apparatus, comprising: (a) a male connector, comprising: (i) an hourglass-shaped protrusion including: (A) a first portion, (B) a second portion, and (C) a third portion positioned between the first and second portions, the third portion being narrower than each of the first and second portions, and (ii) 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; and (b) a female connector, comprising: (i) an hourglass-shaped cavity, the hourglass-shaped cavity being sized and configured to securely receive the hourglass-shaped protrusion, and (ii) a plurality of electrically-conductive pins positioned within the hourglass-shaped cavity, each pin of the plurality of electrically-conductive pins being configured to electrically engage a respective socket of the plurality of electrically-conductive sockets when the hourglass-shaped protrusion is received within the hourglass-shaped cavity. ### Claim 2 (depends on 1) The apparatus of claim 1, the first and second portions being asymmetrical relative to the third portion. ### Claim 3 (depends on 1) The apparatus of claim 1, the plurality of electrically-conductive pins being recessed inside the hourglass-shaped cavity. ### Claim 4 (depends on 1) The apparatus of claim 1, the plurality of electrically-conductive pins comprising at least 100 pins. ### Claim 5 (depends on 1) The apparatus of claim 1, the hourglass-shaped protrusion comprising a plurality of centering holes, each centering hole of the plurality of centering holes being aligned with a respective socket of the plurality of electrically-conductive sockets. ### Claim 6 (depends on 5) The apparatus of claim 5, each centering hole of the plurality of centering holes having a respective lead-in chamfer. ### Claim 7 (depends on 1) The apparatus of claim 1, at least one socket of the plurality of electrically-conductive sockets being positioned on the first portion, at least one socket of the plurality of electrically-conductive sockets being positioned on the second portion. ### Claim 8 (depends on 1) The apparatus of claim 1, the first portion being rectangular. ### Claim 9 (depends on 8) The apparatus of claim 8, the second portion being trapezoidal. ### Claim 10 (depends on 1) The apparatus of claim 1, the hourglass-shaped cavity and hourglass-shaped protrusion being configured to align each pin of the plurality of electrically-conductive pins with a respective one of the plurality of electrically-conductive sockets at the beginning of insertion of the hourglass-shaped protrusion into the hourglass-shaped cavity but before electrical contact is made between the pin and socket. ### Claim 11 (depends on 1) The apparatus of claim 1, the hourglass-shaped protrusion being configured to fit only one way into the hourglass-shaped cavity. ### Claim 12 (depends on 1) The apparatus of claim 1, further comprising a conductor in electrical contact with each pin of the plurality of electrically-conductive pins. ### Claim 13 (depends on 1) The apparatus of claim 1, further comprising a conductor in electrical contact with each socket of the plurality of electrically-conductive sockets. ### Claim 14 (depends on 1) The apparatus of claim 1, the male and female connectors being configured to be connected and disconnected repeatedly without damage to the apparatus. ### Claim 15 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. ### Claim 16 (depends on 15) The apparatus of claim 15, the first and second portions being asymmetrical relative to the third portion. ### Claim 17 (depends on 15) The apparatus of claim 15, the plurality of electrically-conductive sockets comprising at least 100 sockets. ### Claim 18 (depends on 15) The apparatus of claim 15, the hourglass-shaped protrusion comprising a plurality of centering holes, each centering hole of the plurality of centering holes being aligned with a respective socket of the plurality of electrically-conductive sockets. ### Claim 19 (depends on 18) The apparatus of claim 18, each centering hole of the plurality of centering holes having a respective lead-in chamfer. ### Claim 20 An apparatus, comprising: (a) an hourglass-shaped cavity, the cavity being sized and configured to securely receive an hourglass-shaped protrusion of a male connector, the cavity 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 pins positioned within the hourglass-shaped cavity, at least one pin of the plurality of electrically-conductive pins being positioned solely within the third portion, each pin of the plurality of electrically-conductive pins being configured to electrically engage a respective electrically-conductive socket positioned on the hourglass-shaped protrusion of the male connector when the hourglass-shaped protrusion is received within the hourglass-shaped cavity.
