Electronic device with integral connectors
View Patent ↗An electronic device having one or more integral connectors is disclosed. The connector includes an electromagnetically-shielded cavity defined by an outer shell integrally formed in the housing and having a cross-sectional profile of a plug to which the connector may mate. The connector also includes a tongue integrally formed in and extending from a component (such as a printed circuit board) of the electronic device and protruding into the cavity. The tongue may have one or more electrical contacts on one or both sides. The connector may also include one or more snap features for retaining a mated plug at a predetermined force. The connectors may conform to one or more connector standards, such as the Universal Serial Bus (USB) standard and/or the IEEE 1394 (FireWire®) standard. Devices incorporating such integral connectors may be smaller and manufactured less expensively than devices having conventional, non-integral, connectors.
1. An electronic device comprising:
a printed circuit board comprising a tongue integrally formed in one piece with and extending from the printed circuit board, the tongue comprising an electrical contact;
a housing fully enclosing the printed circuit board, the housing comprising:
a connector comprising:
a cavity defined by an outer shell, the outer shell comprising a surface molded in one piece with the housing, the surface facing an interior of the cavity, the cavity having a cross-sectional profile of a plug to which the connector may mate; and
the tongue, wherein the tongue protrudes into a region of the cavity.
2. The connector of claim 1 , wherein properties of the cavity and the tongue comply with requirements of the Universal Serial Bus standard.
3. The connector of claim 1 , wherein properties of the cavity and the tongue comply with requirements of the IEEE 1394 standard.
4. The connector of claim 1 , wherein the outer shell comprises an electromagnetically-shielded portion of the housing.
5. The connector of claim 4 , wherein the outer shell comprises plastic lined with an electromagnetic shielding substrate.
6. The connector of claim 1 , further comprising:
mechanical retention means for retaining the plug at a predetermined force.
7. The connector of claim 6 , wherein the mechanical retention means comprises at least one snap feature within the cavity and coupled to the outer shell to retain the plug at a predetermined force.
8. A electronic device comprising:
a printed circuit board comprising a tongue integrally formed in one piece with and extending from the printed circuit board;
a housing fully enclosing the printed circuit board, the housing comprising:
a connector comprising:
a cavity defined by an electromagnetically-shielded outer shell, the outer shell comprising a surface molded in one piece with the housing, the surface facing an interior of the cavity, the cavity having a cross-sectional profile of a plug to which the connector may mate; and
the tongue, wherein the tongue protrudes into a region of the cavity, the tongue comprising means for forming an electrical connection between the plug and the connector.
9. The connector of claim 8 , further comprising:
mechanical retention means for retaining the plug at a predetermined force.
10. The connector of claim 8 , wherein the mechanical retention means comprises at least one snap feature within the cavity and coupled to the outer shell to retain the plug at a predetermined force.
11. The connector of claim 8 , wherein properties of the cavity and the tongue comply with requirements of the Universal Serial Bus standard.
12. The connector of claim 8 , wherein properties of the cavity and the tongue comply with requirements of the IEEE 1394 standard.
