DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] As discussed above, recent connector designs, such as USB-C and the proprietary Lightning connector by Apple are smaller than USB-A connectors. However, such smaller connectors cannot be configured as nano receivers because there is insufficient space inside the connector housing for the required components. For comparison purposes, FIG. 1 shows a prior art USB-A connector 10 beside a much smaller USB-C connector 12.

[0022] FIG. 2 is a perspective view of a wireless dongle 20, according to an embodiment, having a connector 21 protruding from a housing 22. In one embodiment, connector 21 is a USB-C connector. In another embodiment, connector 21 is a Lightning connector.

[0023] FIG. 3 shows the wireless dongle of FIG. 2, without housing 22, revealing a flexible printed circuit board assembly (PCBA 30) and connected components 32 folded to fit within housing 22, as discussed below.

[0024] FIGS. 4A-4C show three zones of the PCBA 30 and components 32: a connector zone 41 to which connector 21 is connected, a wireless components zone 42 and an antenna zone 43.

[0025] As shown in FIG. 3 and FIGS. 5 and 6, the flexible PCBA is folded in a serpentine configuration, such that the three zones 41, 42 and 43 stack on top of each other, with little or no gap between them. As shown in FIG. 3 and FIGS. 5 and 6, the thin PCBA 30 wraps around the components, in contrast with the prior art wherein the components effectively wrap around a thick circuit board.

[0026] The folded PCBA is inserted into housing 22, which can be made of plastic, to hold the PCBA and components 30, as shown in FIG. 7.

[0027] The wireless dongle 20 is significantly smaller than prior art USB-C receivers 12, as shown in FIG. 8, and protrudes from a host device 90 far less than prior art USB-C receivers 12, as shown in FIG. 9.

[0028] According to an alternative embodiment, the flexible PCBA 30 can be folded in an overlapping fashion, as shown in FIG. 10, to accommodate larger components 32A.

[0029] In embodiments, wireless dongle 20 can function as a nano receiver for larger connectors, such as USB-A.

[0030] In yet other embodiments, wireless dongle 20 can function as a flash memory drive or a security dongle.

[0031] In the embodiments set forth, housing 22 can be constructed from plastic, rubber or other suitable material, and can be assembled from separate parts, or overmolded using common techniques familiar to persons knowledgeable in the art.

[0032] The many features and advantages of the invention are apparent from the detailed specification and, thus, it is intended by the appended claims to cover all such features and advantages of the invention that fall within the true spirit and scope of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
