Abstract

A chassis for a ruggedized modular electronics system is disclosed. The chassis includes an open support structure that is configured to support ruggedized electronics modules. The open support structure allows ambient airflow around the exterior of the ruggedized electronics modules. A first electrical connector is supported by the support structure and a second electrical connector is supported by the support structure. The second electrical connector is electrically coupled to the first electrical connector.

Claims

1. A chassis for a ruggedized modular electronics system, comprising:

an open support structure configured to support ruggedized electronics modules, the open support structure allowing ambient airflow around the exterior of the ruggedized electronics modules;

a first electrical connector supported by the support structure;

a second electrical connector supported by the support structure, the second electrical connector electrically coupled to the first electrical connector; and

a power supply supported by the support structure, wherein the power supply is integrated into a chamber of the support structure, the chamber being environmentally sealed.

2. The chassis of claim 1, wherein the open support structure includes aluminum.

3. The chassis of claim 1, wherein the chamber includes a plurality of heat dissipation structures extending from the exterior surface of the support structure.

4. The chassis of claim 1, further comprising:

a plurality of electrical connectors, at least one of the electrical connectors being of a different type than the other of the electrical connectors.

5. The chassis of claim 1, wherein the electronics modules are each a component of a radio system.

6. A chassis for a ruggedized modular electronics system, comprising:

a means for supporting a first ruggedized electronics module and a second ruggedized electronics module, the means for supporting allowing ambient airflow around the exterior of the first and second ruggedized electronics modules;

a first means for connecting the first ruggedized electronics module to the second ruggedized electronics module, the first means being supported by the means for supporting;

a second means for connecting the second ruggedized electronics module to the first ruggedized electronics module, the second means for connecting being supported by the means for supporting; and

a power supply supported by the means for supporting, wherein the power supply is integrated into a chamber of the means for supporting, the chamber being environmentally sealed.

7. The chassis of claim 6, wherein the means for supporting includes aluminum.

8. The chassis of claim 6, wherein the chamber includes a plurality of heat dissipation structures extending from the exterior surface of the means for supporting.

9. The chassis of claim 6, further comprising:

a plurality of means for connecting, at least one of the means for connecting being of a different type than the other of the means for connecting.

10. The chassis of claim 6, wherein the ruggedized electronics modules are each a component of a radio system.

11. A support structure for a ruggedized modular electronics system, comprising:

a base portion;

two opposing side portions extending from the base portion;

a rear portion extending from the base portion, the rear portion supporting more than one electrical connectors; and

a power supply supported by the rear portion and configured to provide power to ruggedized electronics modules coupled to the electrical connectors, wherein the power supply is integrated into an environmentally sealed chamber of the support structure.

12. The support structure of claim 11, wherein the electrical connectors are at least partially electrically coupled to each other.

13. The support structure of claim 11, wherein the support structure is configured to accommodate an active cooling module.

14. The support structure of claim 11, wherein the two opposing side portions include apertures therethrough.
