Description:
BACKGROUND 
     The numbers and types of electronic devices available to consumers have increased tremendously the past few years, and this increase shows no signs of abating. Devices such as portable computing devices, tablets, desktop computers, laptops, all-in-one computers, cell phones, smart phones, media phones, storage devices, portable media players, navigation systems, monitors and other devices have become ubiquitous. 
     These devices often receive power and share data using various cables. These cables may have connector inserts, or plugs, on each end. The connector inserts may plug into connector receptacles on electronic devices, thereby forming one or more conductive paths for signals and power. 
     Devices typically have openings that allow access to connector receptacles. These openings may provide access to one or more contacts in the receptacles, which may mate with corresponding contacts in connector inserts or electronic devices, such as memory cards. The connector receptacles are often located on a printed circuit board, such as a main or mother board. The one or more contacts in the connector receptacle may connect to corresponding traces on the printed circuit board. 
     Accordingly, in these devices, a connector receptacle resides on a printed circuit board and has an opening aligned (or what may be referred to as “registered”) to an opening in an enclosure in the electronic device. 
     Unfortunately, during shipment and usage, the printed circuit board may shift relative to the device enclosure. This shift, may, in turn, change the position of the opening of the connector receptacle relative to the opening in the device enclosure. A small shift may mar the appearance of the electronic device. A large shift may interfere with the operation of the electronic device. 
     Thus, what is needed are connector receptacles that may aid in maintaining registration or alignment of the connector receptacle to an opening in a device enclosure. 
     SUMMARY 
     Accordingly, embodiments of the present invention may provide connector receptacles that may aid in maintaining registration or alignment of the connector receptacle to an opening in a device enclosure. In various embodiments of the present invention, connector receptacles may help maintain registration or alignment between a printed circuit board, such a main logic board, and an opening in a device enclosure. In various embodiments of the present invention, connector receptacles may help maintain registration or alignment between a printed circuit board the connector receptacle, and an opening in a device enclosure. 
     An illustrative embodiment of the present invention may provide a connector receptacle having a housing. The housing may include a passage. A pin may be placed in the passage such that a first portion extends away from a front of the housing and a rear portion extends away from a rear of the housing. The front portion may be arranged to fit in a cavity or opening in an inside surface of a device enclosure, where the device enclosure encloses the electronic device that includes the connector receptacle. The rear portion may be arranged to fit in a cavity or opening in a top surface of a printed circuit board. 
     By securing a device enclosure and printed circuit board together in this way, the printed circuit board is less likely to move relative to the device enclosure. This may help an opening in the connector to remain aligned to an opening in the device enclosure, thereby maintaining an attractive appearance of the electronic device. This may be particularly helpful when the printed circuit board is positioned vertically during use, since such a position may cause the printed circuit board to sag relative to the device enclosure. 
     In various embodiments of the present invention, the printed circuit board and device enclosure may be oblique, that is, they may not be parallel or at a right angle. In such a situation, pins according to embodiments of the present invention may have one or more portions angled relative to each other. For example, a rear portion of a pin may be angled relative to a front portion of the pin. 
     In various embodiments of the present invention, the connector receptacle may include a cavity to support a number of contacts, each contact having a contacting portion to mate with a corresponding contact on a connector insert or electronic component, such as a memory card. Each contact may further a tail portion extending away from a rear of the housing. These tail portions may form through-hole contacts or surface-mount contacts. An opening of the connector receptacle may align to an opening in the device enclosure. 
     In various embodiments of the present invention, instead of a pin, protrusions may be formed on a device housing. These protrusions may be formed together or separately from the housing. These protrusions may include a first protrusion extending away from a front of the housing and a rear protrusion extending away from a rear of the housing. The front protrusion may be arranged to fit in a cavity or opening in an inside surface of a device enclosure, where the device enclosure encloses the electronic device that includes the connector receptacle. The rear protrusion may be arranged to fit in a cavity or opening in a top surface of a printed circuit board. These protrusions may be formed of plastic, metal, or other material. 
     An illustrative embodiment of the present invention may provide a connector receptacle including a housing having a cavity and a passage, a plurality of contacts located in the cavity of the housing, and a pin. The pin may include a front portion extending away from a front of the housing, a middle portion located in the passage of the housing, and a rear portion extending away from a rear of the housing. 
     An illustrative embodiment of the present invention may provide an electronic device. The electronic device may include a device enclosure having a first opening and a first cavity, a printed circuit board having a first cavity, and a connector receptacle. The connector receptacle may include a housing having a cavity and a passage, a plurality of contacts located in the cavity of the housing, and a pin. The pin may include a front portion extending away from a front of the housing into the cavity in the device enclosure, a middle portion located in the passage of the housing, and a rear portion extending away from a rear of the housing into the cavity in the printed circuit board. The cavity of the housing may be aligned with the opening in the device enclosure. 
     An illustrative embodiment of the present invention may provide a method of assembling an electronic device. This method may include inserting a pin into a passage of a housing of a connector receptacle such that the pin includes a front portion extending away from a front of the housing, a middle portion located in the passage of the housing, and a rear portion extending away from a rear of the housing, inserting the front portion of the pin into an opening in a device enclosure, and inserting the rear portion of the pin into a printed circuit board. 
     Again, in some embodiments of the present invention, instead of a pin, protrusions extending from the housing may be used. These protrusions may be formed with the housing, or they may be formed separately. They may be plastic, metallic, or made from another material. Accordingly an illustrative embodiment of the present invention may provide a connector receptacle. The connector receptacle may include a housing having a cavity, a front protrusion, and a rear protrusion, and a plurality of contacts located in the cavity of the housing. The front protrusion may be arranged to fit in an opening in a device enclosure and the rear protrusion may be arranged to fit in an opening in a printed circuit board. 
     Embodiments of the present invention may provide connector receptacles for various types of devices, such as portable computing devices, tablets, desktop computers, laptops, all-in-one computers, cell phones, smart phones, media phones, storage devices, portable media players, navigation systems, monitors and other devices. These connector receptacles may provide pathways for signals and power compliant with various standards such as Universal Serial Bus (USB), a High-Definition Multimedia Interface (HDMI), Digital Visual Interface (DVI), power, Ethernet, DisplayPort, Thunderbolt, Lightning and other types of interfaces. 
     Various portions of connector receptacle  110  may be formed of various materials. For example, the housings and protrusions may be formed of silicon or silicone, rubber, hard rubber, plastic, nylon, liquid-crystal polymers (LCPs), or other nonconductive material or combination of materials. The contacts, pins, and protrusions may be formed of stainless steel, steel, copper, copper titanium, phosphor bronze, or other material or combination of materials.
