Abstract

A connector position assurance (CPA) device for assuring the engagement of a female connector assembly and a male connector assembly in a connector apparatus, and the connector apparatus having the female connector assembly and the male connector assembly engaged together, when in full-lock position, by the CPA. The female and male connector assemblies having a female terminal position assurance (TPA) device and a male terminal position assurance (TPA) device. During transport, the female TPA is engaged, in a pre-set position or a pre-lock position, to the female connector assembly, while the male TPA is engaged, in a pre-set position or a pre-lock position, to the male connector assembly. Also during transport, a connector position assurance (CPA) device is, at a pre-set position or a pre-lock position, with the female connector assembly. At least a set of terminals is provided into each of the male connector assembly and the female connector assembly when each of their respective male TPA and female TPA is at a pre-set position or a pre-lock position. The set of terminals provided for the male connector assembly is secured thereto when the male TPA thereof is placed at a full-lock position. Similarly, the set of terminals provided for the female connector assembly is secured thereto when the female TPA thereof is placed at a full-lock position. Thereafter, the male connector assembly and female connector assembly are engaged together, and the engagement thereof is assured when the CPA device is placed at a full-lock position.

7. The female connector assembly as in claim 6, wherein when the female TPA device is in full-lock position, the CPA device assures, when in full-lock position, the engagement of the female connector assembly with a male connector assembly.

8. A male connector assembly, comprising:

a first end; and

a second end, having a set of apertures for accommodating therein a set of terminals, wherein the first end includes at least an opening for receiving therein a male terminal position assurance (TPA) device.

9. The male connector assembly as in claim 8, wherein the male TPA device includes members, extending therefrom, for allowing the male TPA device to be at a pre-set position or a pre-lock position during transport of the male connector assembly and at a full-lock position for engaging the set of terminals.

10. The male connector assembly as in claim 9, wherein, when the male TPA device is in a full-lock position, a female connector assembly can be inserted and accommodated within the opening of the second end.
