Abstract

A box nut retainer system includes a panel configured to receive a fastener. The box nut retainer system includes a plurality of retainer legs extending from the panel. The box nut retainer system includes planar bends positioned at distal ends of the plurality of retainer legs. Straight beams extend from the planar bends. The straight beams have engagement angles relative to the plurality of retainer legs.

First claim

The invention claimed is:

1. A box nut retainer system, comprising:
a panel configured to receive a fastener;
a plurality of retainer legs extending from the panel; and
planar bends positioned at distal ends of the plurality of retainer legs, straight beams extending from the planar bends, the straight beams having engagement angles relative to the plurality of retainer legs, wherein an insertion force of the fastener is based on the engagement angles.

2. The box nut retainer system of claim 1 , further comprising a fastener tube that extends through the panel.

3. The box nut retainer system of claim 2 , wherein the fastener tube extends through the panel and defines a fastener intake passage.

4. The box nut retainer system of claim 3 , wherein the fastener intake passage includes an internal circumference that is threaded.

5. The box nut retainer system of claim 4 , wherein the panel is interposed between a mating panel and a fastener panel.

6. The box nut retainer system of claim 4 , wherein the insertion force of the fastener is configured to generate a compression pressure on a mating panel and a fastener panel.

7. The box nut retainer system of claim 1 , wherein the plurality of retainer legs are configured to spread apart such that a plurality of guides abut the fastener.

8. The box nut retainer system of claim 1 , wherein the plurality of retainer legs are positioned a distance away from a fastener tube extending from the panel.

9. The box nut retainer system of claim 8 , wherein the fastener tube is configured to receive M5 fasteners.

10. The box nut retainer system of claim 1 , wherein responsive to the plurality of retainer legs spreading, the straight beams are configured to be directed towards a fastener panel.

11. The box nut retainer system of claim 10 , wherein the straight beams are configured to protrude from the plurality of retainer legs based on the engagement angle.

12. The box nut retainer system of claim 10 , wherein responsive to the plurality of retainer legs spreading, the straight beams are configured to be in contact with a fastener panel.

13. A box nut retainer system, comprising:
a panel configured to receive a fastener;
a fastener tube that extends through the panel and defines a fastener intake passage;
a plurality of retainer legs extending from the panel; and
planar bends positioned at distal ends of the plurality of retainer legs, straight beams extending from the planar bends, the straight beams having engagement angles relative to the plurality of retainer legs, the straight beams are configured to protrude from the plurality of retainer legs based on the engagement angles, wherein an insertion force of the fastener is based on the engagement angles.

14. The box nut retainer system of claim 13 , wherein the panel is interposed between a mating panel and a fastener panel, an insertion force of the fastener is configured to generate a compression pressure on the mating panel and the fastener panel.

15. The box nut retainer system of claim 13 , wherein the plurality of retainer legs are configured to spread out responsive to the insertion of the fastener in the fastener tube such that a plurality of guides abut the fastener.

16. The box nut retainer system of claim 13 , wherein the plurality of retainer legs are positioned a distance away from the fastener passage area extending from the panel.

17. The box nut retainer system of claim 13 , wherein the fastener tube includes an internal circumference that is threaded.

18. The box nut retainer system of claim 17 , wherein the fastener tube is configured to receive M5 fasteners.

19. A box nut retainer system, comprising:
a panel configured to receive a fastener;
a fastener tube that extends through the panel and defines a fastener intake passage, the fastener tube includes an internal circumference that is threaded;
a plurality of retainer legs extending from the panel, wherein the plurality of retainer legs extend at curved orthogonal angles from the upper panel, the plurality of retainer legs being positioned a distance away from the fastener tube and extend from the panel, the plurality of retainer legs are configured to spread towards a fastener panel responsive to the fastener inserted into the fastener tube; and
planar bends positioned at distal ends of the plurality of retainer legs, straight beams extend from the planar bends, the straight beams having engagement angles relative to the plurality of retainer legs, the straight beams are configured to protrude from the plurality of retainer legs based on the engagement angles, wherein an insertion force of the fastener is based on the engagement angles.
