Super-thin USB connector receptacle housings having reduced-wear finger contacts
Structures, methods, and apparatus that provide connector receptacles that have a reduced tendency to scratch and otherwise mar connector inserts, have an aesthetically-pleasing appearance, have an improved tactile response when inserts are inserted, or are very thin or have a low profile. Various examples reduce scratches and wear by utilizing domes, cylinders, balls, or other structures as finger contacts in a connector receptacle. Another example provides aesthetically-pleasing connector receptacle enclosures by forming receptacle enclosures using the same type of material, or material having the same or similar color or texture, as is used for enclosing the electronic device that includes the receptacle. Another example provides an aesthetically-pleasing receptacle enclosure by forming receptacle enclosures that are, in part or in whole, contiguous or formed with the housing. Another example provides a super-thin connector receptacle by removing fingers and portions of a shell along one or more sides.
1. A connector receptacle comprising: a housing having a top, a bottom, a right side, and a left side, wherein the bottom has at least one opening for a finger contact, the right side has at least one opening for a finger contact, the left side has at least one opening for a finger contact, and the top has an absence of openings for a finger contact; and a shield covering at least part of the bottom, right, and left sides, and substantially not covering the top.
2. The connector of claim 1 wherein each of the plurality of fingers comprises a dome-shaped contact.
3. The connector receptacle of claim 2 further comprising a tongue.
4. The connector receptacle of claim 3 further comprising a plurality of contacts located at least partially adjacent to the tongue.
5. The connector receptacle of claim 3 wherein the receptacle is located in a device enclosure, and the housing is formed with the device enclosure.
6. The connector receptacle of claim 3 wherein the shield is formed of one of the group consisting of aluminum, steel, stainless steel, spring steel, and palladium-nickel alloy.
7. The connector receptacle of claim 3 wherein the dome-shaped contacts are formed using palladium-nickel alloy.
8. The connector receptacle of claim 3 wherein the housing is formed of one of the group consisting of plastic, ceramic, and aluminum.
