Abstract
A female electrical terminal includes a securing end and a mating end coupled along a longitudinal axis to the securing end. The mating end includes a housing provided with an opening configured to receive a male contact. A contact pad located within the housing is oriented to be brought into contact with the male contact received within the opening, wherein a surface of the contact pad includes a plurality of protrusions extending from the surface.
Claims21
A female electrical terminal comprising:
- a securing end;
- a mating end coupled along a longitudinal axis to the securing end, the mating end including a housing provided with an opening configured to receive a male contact;
- and
- a contact pad located within the housing and having a surface positioned to contact the male contact received within the opening, wherein the surface of the contact pad includes a plurality of protrusions extending from the surface that are non-uniform in height, wherein one or more contact points are formed between one or more of the plurality of protrusions and the male contact and wherein the one or more contact points migrate over time in response to fretting of original contact points.

A connection assembly comprising:
- a female electrical terminal having a first end and a second end, the first end having an opening and a contact pad located within the first end, wherein a surface of the contact pad is knurled to provide a plurality of protrusions extending from the surface that are non-uniform in height;
- and
- a male electrical terminal having a male contact that is received within the opening of the female electrical terminal and placed in contact with the contact pad, wherein one or more electrical contact points are provided between the plurality of protrusions and the male contact and wherein the one or more electrical contact points migrate over time in response to fretting of electrical original contact points.
