Abstract

Tools and fixtures for assembling a printed circuit board (PCB), such as a main logic board (MLB), in a portable computer device are described. A connector assembly having an electrically conductive gasket mounted on an edge of the MLB is described. In addition, a keyboard assembly including a notched portion of the MLB for accommodating more than one type of keyboard is described. In addition, a PCB assembly having a bracket to support a weak region of the PCB during assembly is described.

First claim

What is claimed is:

1. A connector assembly of a portable computing device, the connector assembly comprising:
a receptacle configured to accept an external connector, wherein the external connector is configured to connect to an external electronic device;
an opening formed in a housing of the portable computing device, the opening configured to substantially conform to the receptacle;
an electrically conductive shield that surrounds the receptacle; and
an electrically conductive gasket located entirely within the housing of the portable computing device, the electrically conductive gasket formed from a foam material and comprising:
an elongated portion configured to provide mechanical and electrical contact with a first portion of the housing, and
at least one finger portion that is mechanically and electrically coupled to the elongated portion, wherein the at least one finger portion physically contacts the shield and is electrically coupled to the receptacle such that a ground path is formed between the external electronic device and the housing of the portable computing device via the electrically conductive gasket;
wherein the shield comprises at least one spring finger configured to physically contact a ground sheath of the connector when the connector is inserted into the receptacle, thereby providing a ground path to a second portion of the housing.

2. The connector assembly recited in claim 1 , wherein the assembly further comprises an electrically conductive adhesive disposed between the at least one finger portion and the elongated portion.

3. The connector assembly recited in claim 1 , wherein the electrically conductive gasket is formed from a sculpted single piece of conductive silicon material.

4. The connector assembly recited in claim 1 , wherein the electrically conductive material is comprised of a silicon foam material with conductive particles embedded therein.

5. The connector assembly of claim 1 , wherein the elongated portion is configured to make direct contact with the first portion of the housing.

6. The connector assembly recited in claim 4 , wherein the conductive particles are comprised of silver.

7. The connector assembly of claim 5 , wherein the first portion of the housing is a bottom case.

8. The connector assembly of claim 7 , wherein the bottom case is anodized at the point of contact with the elongated portion.

9. A portable computing device, comprising:
a housing including a first housing portion and a second housing portion, the second housing portion including an opening therethrough, wherein the opening is configured to accept a separate external connector that connects to a separate external electronic device;
a receptacle located within the housing and proximate the opening, wherein the receptacle is configured to accommodate the external connector; and
an electrically conductive gasket formed from a foam material located entirely within the housing of the portable computing device, the electrically conductive gasket having an elongated gasket portion that is mechanically and electrically coupled with the housing and a finger gasket portion that is electrically coupled to the receptacle, wherein a ground path is formed between the external electronic device and the housing via the electrically conductive gasket; and
a metal shield that surrounds the receptacle and forms part of the ground path;
wherein the metal shield includes at least one spring finger configured to physically contact a ground sheath of the external connector when the external connector is inserted into the receptacle.

10. The portable computing device of claim 9 , wherein the first housing portion is an upper case and the second housing portion is a bottom case.

11. The portable computing device of claim 9 , wherein the metal shield physically contacts the finger gasket portion.

12. The portable computing device of claim 9 , wherein the portable computing device is a laptop computer.

13. The portable computing device of claim 10 , wherein the elongated gasket portion physically contacts the bottom case.

14. A laptop computer, comprising:
a housing including an upper case coupled to a bottom case, the upper case including an opening therethrough, wherein the opening is configured to accept a separate external connector that connects to a separate external electronic device;
a receptacle located within the housing and proximate the opening, wherein the receptacle is configured to accommodate the separate external connector;
a metal shield that surrounds the receptacle, the metal shield including at least one spring finger configured to physically contact a ground sheath of the external connector when the external connector is inserted into the receptacle; and
an electrically conductive gasket formed from a foam material located entirely within the housing of the laptop computer, the electrically conductive gasket having an elongated gasket portion that physically contacts the bottom case and an integrally formed finger gasket portion that physically contacts the metal shield, wherein a ground path is formed from the external electronic device to the bottom case by way of the ground sheath of the external connector, the metal shield, and the electrically conductive gasket, when the external connector is inserted into the receptacle.
