Abstract

An electronic assembly includes an interposer assembly and a cable connector module coupled to the interposer assembly. The interposer assembly includes an array of compressible interposer contacts each having upper and lower mating interfaces defining separable mating interfaces. The cable connector module includes a cable connector having a module substrate including module contacts at a bottom of the module substrate coupled to the upper mating interfaces of the corresponding interposer contacts. The cable connector module includes a backshell including a backshell cavity that receives the cable connector. The backshell includes a compression member engaging the cable connector and pressing the cable connector in the direction of the interposer assembly to compress the interposer contacts.

First claim

a cable connector module coupled to the interposer assembly, the cable connector module including a cable connector having a module substrate including a contact array of module contacts at a bottom of the module substrate, the module contacts being coupled to the upper mating interfaces of the corresponding interposer contacts at a separable mating interface, the cable connector module including a backshell including a backshell cavity, the cable connector received in the backshell cavity, the backshell including a compression member engaging the cable connector and pressing the cable connector in the direction of the interposer assembly to compress the interposer contacts, wherein the compression member is located in the backshell cavity.

2. The electronic assembly of claim 1 , wherein the compression member is supported independent of the interposer assembly and the circuit board by the backshell cavity.

3. The electronic assembly of claim 1 , wherein the compression member extends along at least two different sides of the array of interposer contacts.

4. The electronic assembly of claim 1 , wherein the compression member includes a first spring element and a second spring element spaced apart from the first spring element.

5. The electronic assembly of claim 1 , wherein the compression member includes a plurality of spring elements forming a rectangular compression box pressing against a perimeter of the cable connector.

6. The electronic assembly of claim 1 , wherein the compression member is a wave spring having multiple points of contact with the backshell and having multiple points of contact with the cable connector.

7. The electronic assembly of claim 1 , wherein the compression member includes a mounting tab coupled to the backshell.

8. The electronic assembly of claim 1 , wherein the cable connector module includes a bolster plate located below the interposer assembly, the backshell including mounting hardware coupled to the bolster plate to secure the backshell relative to the circuit board, the compression member being located between the backshell and the bolster plate to compress the interposer contacts.

9. The electronic assembly of claim 1 , wherein the backshell includes an upper wall and a sidewall extending from the upper wall, the sidewall defining the backshell cavity below the upper wall, the backshell including a window through the upper wall, the compression member extending along the window.

10. The electronic assembly of claim 9 , wherein the compression member surrounds a perimeter of the window.

11. The electronic assembly of claim 9 , wherein the cable connector module includes a heat transfer element received in the window in thermal communication with the cable connector in the backshell cavity to dissipate heat from the cable connector.

12. The electronic assembly of claim 1 , wherein the cable connector is a fiber optic connector having an optical engine mounted to the module substrate, the fiber optic connector holding at least one optical fiber optically coupled to the optical engine, the module contacts being electrically connected to the optical engine.
