The present invention relates to adapters, and more specifically to electronic connector adapters and form factor adapters for electronic components.
Many conventional electronic devices consist of a main component, such as a motherboard, and additional supporting components, such as storage devices and input/output devices. In general, the supporting components for such electronic devices are connected to the main component using a receptacle-type connector assembly system. In some devices, the main and supporting components of the electronic device will each be designed with a male connector having a plurality of electrical contacts or pins within. A cable with female connectors corresponding to the male connectors is then provided to span the physical gap between the main component and the supporting component. For example, ribbon cables are commonly used in computing devices, such as handheld, laptop, and desktop computers.
As the demand for portable electronic devices has increased, the need for reducing weight and space requirements of such devices has also increased. Accordingly, in an effort to reduce the amount of space needed for the portable electronic device, many electronic device designs have been modified by eliminating the need for cables. In particular, the male connector on either the main component or the supporting component has been replaced in many devices with a female connector to allow the supporting component to be directly connected to the main component. Unfortunately, many types of electronic devices use supporting components designed and manufactured according to standardized configurations, such as data hard disc drives. As a result, electronic device designers must generally design the main component of an electronic device to accommodate connection of the standardized component. This can represent a challenge for designers, as standardized configurations are typically difficult to integrate into many types of portable device designs.

The present invention is described with reference to the attached figures, wherein like reference numerals are used throughout the figures to designate similar or equivalent elements. The figures are not drawn to scale and they are provided merely to illustrate the instant invention. Several aspects of the invention are described below with reference to example applications for illustration. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the invention. One having ordinary skill in the relevant art, however, will readily recognize that the invention can be practiced without one or more of the specific details or with other methods. In other instances, well-known structures or operations are not shown in detail to avoid obscuring the invention. The present invention is not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and/or concurrently with other acts or events. Furthermore, not all illustrated acts or events are required to implement a methodology in accordance with the present invention.
As described above, one of the main challenges in designing portable devices is accommodating components that have standardized configurations, particularly during assembly. For example, a conventional hard disc drive is substantially flat (i.e., its side surfaces are substantially smaller that it's top and bottom surfaces), but the electrical connectors in such hard disc drives are generally located along side surfaces. Accordingly, flat surface mounting of such hard disc drive devices on, for example, a motherboard is non-trivial. This is illustrated in FIG. 1.
This conventional configuration suffers from several problems. First, if the hard disc drive 102 is added after the motherboard 104 is placed in a housing, additional space in at least the housing must be provided to accommodate the lateral motion of the hard disc drive 102 during assembly. Second, since the hard disc drive 102 must be moved over the surface of motherboard 104, areas 106 and 108 must be substantially devoid of components that could be damaged during motion of the hard disc drive 102. Accordingly, at least a portion of areas 106 and 108 may be unavailable for some types of components. Such components can be relocated to other portions of motherboard 104, but this potentially increases the size of the resulting electronic device. Third, connectors, such as connector 110 or 112, typically include pins or other protruding portions, as described above, which are susceptible to damage due to mishandling. Finally, the force typically required to insert connector 110 into connector 112 is significant. Accordingly, if the hard disc drive 102 is not properly positioned over motherboard 104, the applied force can damage connector 110 or connector 112, or even damage hard disc drive 102 or motherboard 104.
To overcome the various limitations of conventional component mounting configurations in electronic devices, embodiments of the invention provide an electrical connector adapter, with a minimum footprint, for surface mounting electronic device components. In particular, an adapter in accordance with an embodiment of the invention is configured have a first surface with at least one socket for receiving a male or female connector of an existing component and second surface with a plurality of spring loaded pads for contacting a plurality of pads on another component, such as on a surface of a motherboard. This configuration is conceptually illustrated with respect to
Although the various embodiments of the invention will be principally illustrated with respect to the mounting of hard disc drive components, the invention is not limited in this regard. Rather, the various embodiments of the invention can be used with any type of components for an electrical device, including, but not limited to input/output devices, memory modules, and other peripheral devices.
As a result of the configuration of
Electrical connector adapter 212 will now be described in greater detail below with respect to
As used herein with respect to a contact pad or other electrically conductive element, the term “spring-loaded” means that the electrically conductive element includes or is combined with at least one elastically deformable portion. This elastically deformable portion is configured to cause a change in the position or configuration of the contacting portion of the electrically conductive element when force is applied against the electrically conductive elements. For example, in one embodiment of the invention, the plurality of spring-loaded contact pads 318 can comprise a series of leaf-type springs constructed from an electrically conductive composition. However, the invention is not limited in this regard and other types of configurations can be used to provide spring-loaded contact pads.
The configuration in
In the various embodiments of the invention, the housing, socket, and pads in an adapter can be configured to provide any shape or to have any dimensions. However, in some embodiments of the invention, the shape and size of the adapter can be selected such that a combined dimensional footprint of the adapter and associated component is substantially the same as the dimensional footprint of the associated component alone. For example, in the embodiment illustrated in
The term “dimensional footprint”, as used herein, refers to the footprint of a device in terms of area or volume. The term “substantially” as used herein with respect to a quantity, means that the quantity can vary by 10% with respect to a reference quantity.
In some embodiments of the invention, adapter 212 can be configured to include one or more features to facilitate mounting of hard disc drive 202 (including adapter 212) in an electronic device. For example, as shown in
In the various embodiments of the invention, a socket of an electrical connector adapter can be configured in a variety of ways. For example, as shown in
In the embodiment illustrated in
Further, although
Similar to the adapter in
In the various embodiments of the invention, the sockets 616 can be configured in a variety of ways for contacting and retaining pin-type connectors. For example, in addition to being dimensioned to receive pin-type connector 610, sockets 616 can include one or more spring-loaded contact elements (not shown) within housing 614. These contact elements are configured to electrically couple each of pin-type connectors 610 to one of pads 618. In some embodiments of the invention, such contact elements can be configured to be springingly biased against the pin-type connectors 610. In such embodiments of the invention, these contact elements can also provide enough force to retain pin-type connectors 610 in sockets 616 without the need for additional fasteners. However, the invention is not limited in this regard and a fastening system can be provided to pin-type connectors 610 in sockets 616. For example, one or more fasteners can be used to attach adapter 612 to device 602.
Although the exemplary embodiments described above provide right angle adapters, the various embodiments of the invention are not limited in this regard. In other embodiments of the invention, the plurality of spring-loaded contact pads can be configured to extend in other directions. This is illustrated in
As described above, using electrical connector adapters in accordance with the various embodiments of the invention provides several advantages with respect to mounting components in electronic devices. However, electrical connector adapters in accordance with the various embodiments of the invention can also be used to provide form factor adapters for some types of applications.
For example, many types of servers typically utilize removable drive storage systems. In general, a hard disc drive for such a server is generally mounted in a carrier that can be removeably installed in a server system. Over time, the increasing storage needs of the server are typically met by adding additional drives, each mounted individually in a carrier. However, such a configuration typically faces two problems over time. First, such server systems typically have a finite number of slots for adding additional drive carriers. Accordingly, a new server system or at least a significant hardware and/or software upgrade is needed to add additional drive carriers. Second, as hard disc drive technologies evolve over time, they are generally applied to hard disc drives with smaller form factors. Accordingly, the storage capacity of a server having drive carriers configured for older form factors is effectively limited by the extent such advanced hard disc drive technologies have been applied to compatible hard disc drives.
However, hard disc drive designs generally conform to particular form factor configurations. In particular, hard disc drive form factors have been generally designed such that the length and width of a hard disc drive of a particular form factor are equal to the width and ½ the length, respectively, of a hard disc drive of a preceding form factor. Furthermore, the height of a hard disc drive of a particular form factor is generally less than or equal to the height of a hard disc drive of a preceding form factor. Consequently, it is typically possible to arrange two or more hard disc drives of a particular form factor in volume previously occupied by a hard disc drive of a preceding form factor.
One problem with many conventional form factor adapters for disc drive is that the connection between the larger form factor disc drive interface and the smaller form factor disc drive must typically be accomplished via the use of ribbon cable-type connectors. However, when attempting to use two or more smaller form factor disc drives in the space of a larger form factor disc drive, it is difficult to route such ribbon-type connectors in the space available. Accordingly, the volume required by such smaller form factor disc drives is effective larger than that of the larger form factor disc drive. Furthermore, the use of ribbon-type connectors is often problematic for maintenance purposes. In particular, removal of a disc drive requires not only that the disc drive be disengaged from the housing, but the manipulation of the ribbon-type cable to electrically disconnect such disc drives. Such manipulations, if occurring frequently, can result in degrading of the ribbon-type connection, requiring replacement or resulting in access errors.
Accordingly, based on the relationship between the different form factors, a form factor adapter using electrical connector adapters in accordance with an embodiment of the invention can be provided. The use of such adapters eliminates the various difficulties associated with ribbon-type connectors, improving reliability of the devices and facilitating maintenance of the systems that the disc drives are attached to. This is shown below with respect to
The hard disc drive device 800 is assembled for use as follows. First, electrical connector adapters 802 are inserted into connectors 812 of hard disc drives 804, as described above with respect to
In the exemplary embodiment illustrated in

Afterwards, paddle board 904 can be attached to hard disc drive device 800 and secured in place using paddle board fasteners 907. In the embodiment illustrated in
