Electrical crimp terminal

An electrical terminal comprising:

• a crimp barrel extending along a longitudinal axis between a contact end and a device end, the crimp barrel having an interior side that defines a channel extending along the longitudinal axis, the crimp barrel configured to mechanically hold and electrically connect to one or more electrical conductors of an electrical device received in the channel, the crimp barrel including multiple primary serrations and multiple micro-serrations in a serration array, the primary serrations and the micro-serrations being groove-shaped recesses formed along the interior side, the micro-serrations having a smaller size relative to the primary serrations, the micro-serrations arranged in groups of at least one micro-serration, the groups of the micro-serrations and the primary serrations arranged in an alternating sequence along the longitudinal axis such that one of the primary serrations is disposed between adjacent groups of micro-serrations and one of the groups of micro-serrations is disposed between adjacent primary serrations.

An electrical terminal comprising:

• a crimp barrel having an interior side and an exterior side, the interior side of the crimp barrel defining a channel that extends along a longitudinal axis, the crimp barrel configured to mechanically hold and electrically connect to one or more electrical conductors of an electrical device received in the channel, the crimp barrel including multiple primary serrations spaced apart along the longitudinal axis, adjacent primary serrations being separated from one another by a band, the crimp barrel further including at least one micro-serration on the band such that the at least one micro-serration on the band is disposed between the adjacent primary serrations, the primary serrations and the at least one micro-serration being groove-shaped recesses formed along the interior side, the micro-serrations having a smaller size relative to the primary serrations,
• wherein the primary serrations and the at least one micro-serration define barrel teeth along the interior side of the crimp barrel, each barrel tooth having a top surface that faces the channel and two tapered sides extending from corresponding edges of the top surface, the edges of the barrel teeth configured to engage and scrape against the one or more electrical conductors during a crimping operation to form metal-to-metal contacts.
