Abstract

A chassis to receive a line replaceable module including a molded body formed from a composite material, a card guide integrally formed in the molded body to receive the line replaceable module, the card guide including a card guide wall integrally formed in the molded body and extending outwardly from the molded body, and a plurality of tolerance features disposed within the card guide to retain the line replaceable module.

Claims

1. A chassis to receive a line replaceable module, the chassis comprising:

a molded body formed from a composite material;

a card guide integrally formed in the molded body to define an opening receptive of the line replaceable module, the card guide including card guide walls integrally formed in the molded body and extending outwardly from the molded body;

a plurality of tolerance features disposed in pairs on opposing faces of the card guide walls within the card guide to retain the line replaceable module between corresponding respective tolerance features of each of the pairs;

conductive mesh, which is embedded within an interior of the molded body and which extends along a length of the molded body;

conductive mesh walls respectively extending from the conductive mesh through the interior of the molded body toward an interior of and along a length of corresponding ones of the opposing card guide walls;

conductive strips respectively extending along the opposing faces of the corresponding ones of the card guide walls in the opening; and

conductive tabs respectively extending from corresponding ones of the conductive mesh walls, through the opposing faces to the opening and the corresponding ones of the conductive strips.

2. The chassis of claim 1, wherein the card guide has a U channel shape.

3. The chassis of claim 1, wherein the plurality of tolerance features are disposed in the pairs on the opposing walls of the card guide such that tips of the corresponding respective tolerance features of each of the pairs contact opposite sides of the line replaceable module.

4. The chassis of claim 1, further comprising at least one bolt hole flange formed with the molded body.

5. The chassis of claim 1, wherein the composite material is electrically conductive.

6. The chassis of claim 1, wherein the molded body provides vibration dampening.

7. A chassis to receive a line replaceable module, the chassis comprising:

a U shaped card guide integrally formed in a molded body to define an opening receptive of the line replaceable module,

the U shaped card guide including a first guide wall extending outwardly from a surface of the molded body and a second guide wall extending outwardly from the surface of the molded body, and

the first and second guide walls having complementary faces facing one another in opposite directions;

a plurality of tolerance features disposed in pairs on the complementary faces of the first and second guide walls such that tips of corresponding respective tolerance features of each of the pairs contact opposite sides of the line replaceable module for retaining the line replaceable module in the U shaped card guide;

conductive mesh, which is embedded within an interior of the molded body and which extends along a length of the molded body;

conductive mesh walls respectively extending from the conductive mesh through the interior of the molded body toward an interior of and along a length of corresponding ones of the first and second card guide walls;

conductive strips respectively extending along the complementary faces of the corresponding ones of the first and second card guide walls in the opening; and

conductive tabs respectively extending from corresponding ones of the conductive mesh walls, through the complementary faces to the opening and the corresponding ones of the conductive strips.
