2. The connector assembly in accordance with claim 1 , wherein the second-end of the planar-member includes a plurality of hinges.

3. The connector assembly in accordance with claim 1 , wherein the hinge defines a base and a web, said base attached to the leading-edge of the outer-surface, said web extending from a top of the base to the planar-member, said base defines a rear-facing surface characterized as having a curved-transition between the outer-surface of the connector-body and the web.

4. The connector assembly in accordance with claim 3 , wherein the curved-transition is characterized as having a radius in a range of 0.3 mm to 0.35 mm.

6. The connector assembly in accordance with claim 3 , wherein the planar-member has a planar-member-thickness in a range of 0.5 mm to 1.0 mm.

7. The connector assembly in accordance with claim 1 , wherein the flex-lock feature defines a lead-angle on the hook-side configured to guide the flex-lock feature into the slot to a locked-position when the lock feature is moved from an open-position to the locked-position.

8. The connector assembly in accordance with claim 7 , wherein the hook-side exerts an engagement-force on the locking-shelf in a range of 30 Newtons to 45 Newtons when the lead-angle engages the locking-shelf.

9. The connector assembly in accordance with claim 1 , wherein the planar-member isolates the electrical-terminals within the cavities when the hook-side of the flex-lock feature engages the locking-shelf.

10. The connector assembly in accordance with claim 1 , wherein the slot defines apertures located on a first-side and a second-side of the connector-body, said apertures configured to receive a tool to release the hook-side from the locking-shelf when the lock feature is in a locked-position.

11. The connector assembly in accordance with claim 1 , wherein the connector-body is formed of a dielectric polymeric material comprising at least 33% glass-fill.

12. The connector assembly in accordance with claim 1 , wherein the hinge enables a swing of the planar-member through a swing-angle of up to 45-degrees when the lock feature is moved from an open-position to a locked-position.

13. A connector, comprising:

a connector-body configured to receive electrical-terminals disposed within cavities defined by the connector-body, said connector-body defining a front-face and a rear-face, said rear-face defining terminal-apertures configured to insertably receive the electrical-terminals, said connector-body defining a slot in an outer-surface extending along a lateral-axis of the connector-body, said slot partially enclosed by a locking-shelf extending in a longitudinal-direction, said connector-body including a lock feature formed integral to the connector-body configured to releasably lock the electrical-terminals within the cavities, said lock feature having a planar-member having a first-end defining a flex-lock feature and second-end attached by at least one hinge to a leading-edge of the outer-surface of the connector-body proximate the front-face, said planar-member extending from the at least one hinge along a longitudinal-axis of the connector-body orthogonal to the lateral-axis overlaying the outer-surface and terminating at the flex-lock feature, said flex-lock feature extending along a width of the planar-member parallel to the lateral-axis and disposed within the slot, said flex-lock feature defining a hook-side and a wall-side, said hook-side oriented toward the rear-face and said wall-side oriented toward the front-face, said hook-side configured to releasably engage the locking-shelf, said wall-side configured to engage a portion of the electrical-terminals when the hook-side engages the locking-shelf, wherein when a removal-force is applied to the electrical-terminals, the removal-force is transferred through the hook-side to the locking-shelf, thereby inhibiting removal of the electrical-terminals from the cavities.

14. The connector in accordance with claim 13 , wherein the at least one hinge defines a base and a web, said base attached to of the outer-surface, said web extending from a top of the base to the planar-member, said base defines a rear-facing surface characterized as having a curved-transition between the outer-surface of the connector-body and the web.

15. The connector in accordance with claim 13 , wherein the flex-lock feature defines a lead-angle on the hook-side configured to guide the flex-lock feature into the slot to a locked-position when the lock feature is moved from an open-position to the locked-position.
