In at least some embodiments, the shell 102 and the removable endpiece 104 include holes 140 for receiving a fastener 118, such as, for example, a screw, bolt, or pin. In at least some embodiments, the holes 140 in one, or both, of the shell 102 and the removable endpiece 104 are threaded. In at least some embodiments, the shell 102 and the removable endpiece 104 include any other suitable attachment arrangement such as, but not limited to, a ridge/detent arrangement (for example, at least one ridge on the shell 102 or removable endpiece 104 (or both) and at least one detent on the removable endpiece or the shell (or both)), a tab/depression arrangement (for example, at least one tab on the shell 102 or removable endpiece 104 (or both) and at least one depression on the removable endpiece or the shell (or both) to receive and retain a tab), or the like or any combination of thereof or any combination of these arrangements and fasteners.

[0039] FIGS. 2A and 2B illustrate one embodiment of the removable endpiece 104. The removable endpiece 104 includes a base 134 and an adapter 120 coupled to the base 134. In at least some embodiments, a portion of the adapter 120 is embedded in the base 134. The adapter 120 is configured for coupling the case 100 and the portable electronic device 150 to an external device, a docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement.

[0040] The adapter 120 includes a male plug 122 for insertion into a female socket of the portable electronic device 150, a contactor 121 opposite the male plug 122, first contacts 124 (FIG. 3) disposed on the male plug for electrically coupling to device contacts 154 (FIG. 3) of the portable electronic device, and second contacts 126 disposed on the contactor 121 for coupling the portable electronic device to an external device, a docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement. The first contacts 124 on the male plug 122 are electrically coupled to the second contacts 126 (for example, by wires or traces on a printed circuit board or any combination thereof) so that the adapter can carry power or data or both between an external device and the portable electronic device.

[0041] In at least some embodiments, the contactor 121 has a flat surface upon which the second contacts 126 are exposed, as illustrated in FIG. 2A. In at least some embodiments, the flat surface of the contactor 121 is perpendicular to the direction that the male plug 122 extends. In at least some embodiments, the flat surface of the contactor 121 is parallel to the adjacent surface of the base 134, as illustrated in FIG. 2A. In at least some embodiments, the second contacts 126 are circular. In at least some embodiments, the second contacts 126 are arranged in at least two rows of contacts. In at least some embodiments, the two rows are offset from each other. Any other suitable arrangement or type of contacts or contactor can be used.

[0042] In at least some embodiments, the adapter 120 forms a male structure 136 extending out of the base 134 for coupling to a female connector (not shown) or any other suitable connector of an external device, a docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement. In at least some embodiments, the male structure 136 can have an asymmetric shape that can facilitate correctly coupling the case 100 to the external device, docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement. In the embodiment illustrated in FIGS. 2A and 2B, the male structure 136 has a first edge 142 that is straight and a second edge 144, opposite the first edge, which is curved. A female connector of the external device, docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement can be shaped similarly to the male structure 136 so that the male structure 136 of the case only fits easily into the female connector of the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement in one orientation. This asymmetry of some embodiments of the male structure 136 of the case 100 facilitates correct coupling of the case with the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement so that the second contacts 126 correctly and reliably mate with corresponding contacts on the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement.

[0043] In at least some embodiments, the adapter 120 forms a female structure 137 (i.e., a recessed structure) extending inward relative to the base 134 for coupling to a male connector (not shown) or any other suitable connector of an external device, a docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement, as illustrated in FIG. 5. In at least some embodiments, the female structure 137 can have an asymmetric shape that can facilitate correctly coupling the case 100 to the external device, docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement. In the embodiment illustrated in FIG. 5, the female structure 137 has a first edge 142 that is straight and a second edge 144, opposite the first edge, which is curved. A male connector of the external device, docking cradle 160 (see, FIGS. 4A and 4B), or other docking arrangement can be shaped similarly to the female structure 137 so that the female structure 137 of the case only fits easily into the female connector of the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement in one orientation. This asymmetry of some embodiments of the female structure 137 of the case 100 facilitates correct coupling of the case with the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement so that the second contacts 126 correctly and reliably mate with corresponding contacts on the external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement.

[0044] In at least some embodiments, the contactor 121 of the adapter 120 is flush with a surface of the base 134 of the removable endpiece 104, as illustrated in FIGS. 6A and 6B. In at least some embodiments, adjacent surfaces of the contactor 121 and base 134 can appear to be uniform and not visually distinct, other than the presence of the second contacts 126, as illustrated in FIGS. 6A and 6B. In at least some embodiments, the contactor 121 or the base 134 includes one or more locating features, such as locating holes 162 or locating pins (not shown), for locating the case 100 relative to an external device, docking cradle 160 (FIGS. 4A and 4B), or other docking arrangement, which includes complementary locating features (for example, locating pins or locating holes, respectively), as illustrated in FIG. 6B.

[0045] In at least some embodiments, the removable endpiece 104 or the adapter 120 includes a female connector 130, such as a USB-A, USB-B, USB-C, Micro-USB, Mini-USB, or Lightning connector or the like. In at least some embodiments, the female connector 130 is spaced apart from the male structure 136 or contactor 121 or both. The female connector 130 includes third contacts 132 (FIG. 3) that are electrically coupled to the first contacts 124 (for example, by wires or traces on a printed circuit board or any combination thereof).

[0046] In at least some embodiments, the removable endpiece 104 also includes a port 138. In at least some embodiments, the port 138 can be similar in size and shape to the female connector 130 and the case 100 can include a plug (not shown) that can fit snugly in either the port or the female connector. The plug (not shown) may be useful to cover the female connector 130 when not in use. When the female connector 130 is in use, the plug (not shown) can be inserted into the port 138 so that it is not lost.

[0047] FIGS. 4A and 4B illustrate the case 100 disposed in, or otherwise attached to, a docking cradle 160.

[0049] FIG. 7A illustrates another embodiment of a removable endpiece 104 that, in addition to any or all of the elements described above, includes at least one tab 170 and at least one pin 172. Any of the other embodiments of the removable endpiece 104 described herein can be modified to include at least one tab 170, at least one pin 172, or any combination thereof. FIG. 7B illustrates another embodiment of a shell 102 that includes at least one tab receptacle 174 and at least one pin receptacle 176. Any of the other embodiments of the removable endpiece 104 described herein can be modified to include at least one tab receptacle 174, at least one pin receptacle 176, or any combination thereof. FIGS. 7C and 7D illustrate the removable endpiece 104 of FIG. 7A inserted into the shell 102 of FIG. 7B to form a case 100 within which a mobile device 150 is contained or containable.

[0050] In at least some embodiments, when the removable endpiece 104 is inserted into the shell 102, each pin 172 of the removable endpiece engages and extends into at least a portion of a pin receptacle 176 of the shell, as illustrated in the cross-sectional view of FIG. 7E. A rearrangement of the pin(s) 172 and pin receptacle(s) 176 can be used so that, in at least some embodiments, the shell 102 includes at least one pin 172 and the removable endpiece 104 includes at least one pin receptacle 176. In at least some embodiments, the shell includes at least one pin 172 and at least one pin receptacle 176 and the removable endpiece includes at least one pin and at least one pin receptacle with the pin(s) of the shell configured to engage the pin receptacle(s) of the removable endpiece and the pin(s) of the removable endpiece configured to engage the pin receptacle(s) of the shell.

[0051] In at least some embodiments, a pin 172 or pin receptacle 176 (or a central position between two or more pins or pin receptacles) is positioned, laterally, at a lateral center of the removable endpiece 104 or shell 102 (or both) or within 5%, 10%, 15%, 20%, or 25% of the lateral width of the removable endpiece or shell (or both) from the lateral center of the removable endpiece 104 or shell 102, as illustrated in FIGS. 7A and 7B. In at least some embodiments, a single pin 172 and pin receptacle 176 is disposed on a back side 105 of the shell 102 and removable endpiece 104, as illustrated in FIG. 7D, although any other positioning of the pin and pin receptacle can be used.

[0052] In at least some embodiments, the pin(s) 172 and pin receptacle(s) 176 can facilitate alignment of the removable endpiece 104 with the shell 102 or the mobile device 150 inserted into the shell. In at least some embodiments, the pin(s) 172 and pin receptacle(s) 176 can facilitate maintenance of contact between the removable endpiece 104 and the mobile device 150 contained within the shell 102. For example, the pin(s) 172 and pin receptacle(s) 176 can resist flexing of the removable endpiece 104 away from the mobile device 150, which may result, for example, in disengagement of the male plug 112 or contacts 124 of the male plug from the contacts 154 of the mobile device.

[0053] In at least some embodiments, the pin(s) 172 can be manually disengaged from the pin receptacle(s) 176 by, for example, application of manual force, application of manual flexing to the removable endpiece 104 or shell 102 (or both), or the like or any combination thereof. In at least some embodiments, the amount of manual force, manual flexing, or the like that is required for disengagement of the pin(s) 172 from the pin receptacle(s) 176 is more than expected during normal usage of the shell 102 and removable endpiece 104.

[0054] In at least some embodiments, when the removable endpiece 104 of inserted into the shell 102, each tab 170 of the removable endpiece is inserted into a tab receptacle 174 of the shell. In at least some embodiments, each (or at least one) tab 170 is undercut (e.g., the tab is a dovetail tab), as illustrated in FIG. 7A, so that the sidewall 175 of each tab receptacle 174 extends beneath a distal surface 171 of the tab, as illustrated in the cross-sectional view of FIG. 7F.

[0055] In at least some embodiments, the sidewall 175 of each tab receptacle 174 is sloped to fit into the undercut of the tab 170, as illustrated in FIG. 7F. In at least some embodiments, this arrangement of the sidewall 175 of the tab receptacle 174 extending into the undercut of the tab 170 and below the distal surface 171 of the tab resists flexing of an edge of the shell 102, along which the tab receptacle is disposed, away from the removable endpiece or mobile device 150.

[0056] In at least some embodiments, at least one tab 170 is disposed on opposite sides (e.g., top and bottom sides) of the removable endpiece 104, as illustrated in FIGS. 7C and 7D. In at least some embodiments, the removable endpiece 104 includes at least one pair of tabs 170 directly opposite each other. The embodiment of the removable endpiece 104 of FIGS. 7C and 7D illustrates two pairs of tabs 170 directly opposite each other. In other embodiments, a pair of tabs 170 on opposite sides of the removable endpiece 104 are not directly opposite each other but are laterally staggered relative to each other.

[0057] In at least some embodiments, this arrangement of a pair of tabs 170 on opposite sides of the removable endpiece 104 resists flexing of the opposing edges of the shell 102, along which the tab receptacles 174 are disposed, away from the removable endpiece or mobile device 150. In at least some embodiments, this arrangement of a pair of tabs 170 on opposite sides of the removable endpiece 104 resists spreading of the opposing edges of the shell 102 apart from each other.

[0058] In at least some embodiments, a distal surface 171 of at least one (or each) tab 170 is flush with an exterior surface 103 of the shell 102, as illustrated in FIGS. 7C and 7D. In other embodiments, a distal surface 171 of at least one (or each) tab 170 protrudes from, or is depressed relative to, the exterior surface 103 of the shell 102.

[0059] In at least some embodiments, a tab 170 or tab receptacle 174 (or a central position between two or more tabs or tab receptacles) is positioned, laterally, at a lateral center of the removable endpiece 104 or shell 102 (or both) or within 5%, 10%, 15%, 20%, or 25% of the lateral width of the removable endpiece or shell (or both) from the lateral center of the removable endpiece 104 or shell 102, as illustrated in FIGS. 7A and 7B.

[0060] In at least some embodiments, a docking button 180 is part of, or attached to, the case 100, as illustrated in FIG. 7D. In at least some embodiments, the case 100 or docking button 180 can include a platform 182 or a mounting neck 184 or both, where the platform has a larger diameter than the mounting neck or docking button or both and the mounting neck has a smaller diameter than the docking button. The docking button 180 can be used to attach the case 100 and mobile device 150 contained into the case to a dock or other 160. Examples of docking buttons, platforms, mounting necks, and docks for use with docking buttons can be found at U.S. patent application Ser. Nos. 18/590,837 and 18/612,977, both of which are incorporated herein by reference in their entireties.

[0061] The above specification provides a description of the structure, manufacture, and use of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention also resides in the claims hereinafter appended.
