Abstract

Latch assembly including a latch arm, having first and second length edges and first and second width edges. The latch arm includes a latch pawl, a pivot connector, and a stabilizing member, positioned in a plane. The latch pawl connected to the first width edge and providing spring force resisting deflection non-parallel to the plane. The pivot connector and stabilizing member formed within an area of the latch arm. The stabilizing member extending distally relative to the second width edge to the pivot connector, and providing spring force resisting deflection parallel to the plane. The component and latch assembly including a component having first and second faces being adjacent and perpendicular. The latch arm rotatably mounted on the second face between latched and unlatched positions. Assembly including an embossment positioned to deflect the latch pawl during latching so the latch arm sits raised upon the embossment in the latched position.

First claim

What is claimed is:

1. A method comprising:
connecting a mounting bracket to a second face of a component, the component having a first face, the second face, and a third face;
connecting a handle pawl pin to the mounting bracket;
connecting a latch arm, having a first length edge, a second length edge, a first width edge, and a second width edge to the mounting bracket and positioning the mounting bracket so that the latch arm is sandwiched between the mounting bracket and the second face, wherein the latch arm includes a latch pawl, a pivot connector, and a stabilizing member, and is positioned in a plane;
connecting the latch pawl to the first width edge of the latch arm and providing spring force resisting deflection non-parallel to the plane;
forming the pivot connector within an area of the latch arm;
forming the stabilizing member being within the area of the latch arm and extending distally relative to the second width edge to connect to the pivot connector, the stabilizing member providing spring force resisting deflection parallel to the plane; and
positioning an embossment on the second face of component to deflect the latch pawl during latching of the latch arm such that the latch arm sits raised upon the embossment and engages the latch pawl pin in the latched position, the component docking one or more electrical signal connectors to a component bay at the second face, the latch pawl pin being configured to extend towards the component from the component bay thereby decreasing the distance between the one or more connectors and a location of force by the latch pawl and the latch pawl pin, the reducing of the distance reducing a likelihood of undocking of the component from the component bay.

2. The method of claim 1 , further comprising constructing the latch arm, stabilizing member, pivot connector, and latch pawl from a single piece of material.

3. The method of claim 1 further comprising constructing the latch arm, stabilizing member, pivot connector, and latch pawl from spring steel.

4. The method of claim 1 , wherein the stabilizing member and the pivot connector define an opening which traces the stabilizing member and the pivot connector, and is located within the area of the latch arm.

5. The method of claim 1 , further comprising partially filling in the opening via damping material.

6. The method of claim 5 , wherein the damping material has a durometer generally in the range of 15 to 70.

7. The method of claim 5 , wherein the damping material is one or more selected from the group consisting of room temperature vulcanizing epoxy, room temperature vulcanizing silicone, room temperature vulcanizing rubber, and grease.

8. The method of claim 1 , further comprising connecting a handle to the latch arm and positioning the handle on the second width edge.

9. The method of claim 1 , further comprising constructing a toothed pivot connector having an inner and outer circumference, and having one or more teeth which form one or more pockets within the area of the latch arm, the one or more teeth positioned on the outer circumference of the toothed pivot connector.

10. The method of claim 1 , further comprising constructing a toothed stabilizing member having one or more teeth which form one or more pockets within the area of the latch arm.

11. A system comprising:
a component, inserted into a component bay having a latch pawl pin, wherein the component docks one or more connectors to the component bay, the one or more connectors being electrical signal connectors, the one or more connectors being positioned on a first face of the component;
the component having the first face and a second face, the first face and the second face being adjacent, perpendicular, and having a shared edge;
a mounting bracket, connected to the second face;
a handle pawl pin connected to the mounting bracket;
a latch arm, having a first length edge, a second length edge, a first width edge, and a second width edge, connected to the mounting bracket and positioned so that the latch arm is sandwiched between the mounting bracket and the second face;
the latch arm being rotatable between a latched position and an unlatched position, the length edges parallel to the shared edge in the latched position and non-parallel to the shared edge in the unlatched position;
the latch arm including a latch pawl, the latch pawl being connected to the first width edge of the latch arm and providing spring force resisting deflection non-parallel to the plane;
an embossment positioned on the component to deflect the latch pawl during latching of the latch arm such that the latch arm sits raised upon the embossment and engages the latch pawl pin in the latched position, the latch pawl pin being configured to extend towards the component from the component bay thereby decreasing the distance between the one or more connectors, the reducing of the distance reducing a likelihood of undocking of the component from the component bay.
