Electrical connector including tubular wire connection portion and pin connection portion

An aftertreatment system comprising:

• a heater comprising a pin;
• a heater power source comprising a wire;
• and
• an electrical connector comprising:
• a tubular wire connection portion having a recess in which the wire is insertable, wherein the recess extends in a first direction, and wherein the tubular wire connection portion is configured to be crimped onto the wire, and
• a pin connection portion comprising:
• first and second projections extending from the tubular wire connection portion,
• a first through hole that extends through the first projection,
• a second through hole that extends through the second projection and is aligned with the first through hole, and
• a third through hole that is defined by the first projection and the second projection and extends in a direction transverse to the first and second through holes,
• wherein the first and second through holes are configured to receive a fastener and to be moved towards each other upon fastening of the fastener, and
• wherein the third through hole is configured to receive the pin and to clamp the pin when the first and second through holes are moved towards each other by the fastener.

An electrical connector comprising:

• a first end;
• a second end opposite of the first end;
• a tubular wire connection portion disposed along the second end, the tubular wire connection portion having:
• a recess in which a wire is insertable, wherein the recess extends in a first direction, and
• a slot extending in the first direction along the recess,
• wherein the tubular wire connection portion is configured to be crimped onto the wire;
• a pin connection portion disposed along the first end, the pin connection portion comprising:
• first and second projections extending in the first direction from the tubular wire connection portion to the first end,
• a first through hole that extends through the first projection,
• a second through hole that extends through the second projection and is aligned with the first through hole, and
• a third through hole that is defined by the first projection and the second projection and extends in a direction transverse to the first and second through holes,
• wherein the first and second through holes are configured to receive a fastener and to be moved towards each other upon fastening of the fastener, and
• wherein the third through hole is configured to receive a pin and to clamp the pin when the first and second through holes are moved towards each other by the fastener;
• and
• a flat surface that extends continuously in the first direction from the tubular wire connection portion to the first end.
