Definitions
- This disclosure relates generally to waterproof housings for mobile electronic devices and waterproof adapters for connecting accessory devices to the mobile electronic devices encased within the waterproof housings while not compromising the waterproof nature of the housings.
- Mobile electronic devices such as smartphones, portable media players, personal computers, e-readers, tablet computers, and digital audio players, are becoming increasingly important in peoples' day-to-day lives. People rely on mobile electronic devices to communicate with others, engage in commerce, listen to music, watch videos, and manage personal calendars, just to name a few. Due to the high cost of mobile electronic devices, there is a strong incentive to protect these devices from physical damage. Protective cases are readily available, but most of these cases are designed to simply protect electronic devices from drop and crush-induced damage and do not provide sufficient protection against liquid intrusion. For cases that protect against liquid intrusion, connection of a corded accessory device, such as corded headphones or fitness sensors, typically requires opening a port door on the case, which creates an opening for liquid intrusion and renders the case no longer waterproof.

- Liquids can damage sensitive electrical components within mobile devices. It is therefore desirable to develop an apparatus that prevent liquids from contacting sensitive electrical components while also not interfering with the functionality or usability of the mobile device.
- a wide variety of protective cases are available for mobile devices, but most fail to provide sufficient protection against liquid intrusion. Those cases that do protect against liquid intrusion typically fail to remain waterproof when a user accesses a physical feature of the electronic device. For example, if a user wants to listen to music through headphones while jogging, the user must open an access port on the case and insert a headphone plug into a headphone jack (i.e. a physical feature) of the mobile device. The access port on the case remains open while headphone plug is connected to the headphone jack in the electronic device.
- the case is not waterproof during this period of time, and the electronic device is susceptible to liquid intrusion from, for example, rain while the user is jogging.
- a waterproof or water-resistant housing 60 can be configured to encase and protect a mobile electronic device 70 from liquid intrusion.
- the housing 60 can include an aperture 40 that allows a user to access a feature (e.g. jack, switch, fingerprint scanner, or touchscreen) associated with the mobile electronic device 70 while the device remains encased in and protected by the housing.
- a feature e.g. jack, switch, fingerprint scanner, or touchscreen
- the user can connect an accessory device (e.g. headphones, microphone, speaker, battery charger, external data storage device, auxiliary antenna, global positioning system (GPS), heart rate sensor, cadence sensor, etc.) to a jack 72 (e.g. female connector) in the mobile electronic device (see, e.g. FIG. 8B ).
- an accessory device e.g. headphones, microphone, speaker, battery charger, external data storage device, auxiliary antenna, global positioning system (GPS), heart rate sensor, cadence sensor, etc.
- a liquid-tight seal can be formed by coupling an accessory connector (e.g. the accessory connector 9 shown in FIGS. 1 and 7 ) associated with the accessory device to the housing 60 .
- a liquid-tight seal can be formed by inserting a port-sealing bung (e.g. the port-sealing bung 25 shown in FIG. 2 or 5 ) into the aperture 40 .
- an accessory device can include an accessory connector 9 that permits the accessory device to be electrically connected to the mobile electronic device 70 .
- the accessory connector 9 can include a jack plug 10 extending from a body 13 .
- the body 13 of the accessory connector can include one or more grasping features (e.g. ridges, knurls, depressions, rubber coating, etc.) that permit a user to easily grasp the accessory connector with their fingers during insertion and removal of the accessory connector.
- the accessory connector 9 can also include a threaded feature 12 and a jack plug gasket 11 .
- the jack plug gasket 11 can be an O-ring or other suitable sealing component.
- the accessory connector 9 by way of the threaded feature 12 and jack plug gasket 11 , can be configured to provide a liquid-tight seal between the accessory connector and a connector aperture 40 in the housing 60 (see, e.g., FIG. 2 ), thereby preventing water from entering an interior volume of the housing and damaging sensitive components within the mobile electronic device stored therein.
- the accessory connector 9 can include a threaded feature 12 (see, e.g., FIG. 1 ) to permit the accessory connector to removably engage the housing 60
- the accessory connector 9 can include cam feature (see, e.g., FIG. 3 ) to permit the accessory connector to removably engage the housing 60

No. 9,300,078, which claims the benefit of U.S. Provisional Patent Application No. 61/869,622 filed on Aug. 23, 2013, U.S. Provisional Patent Application No. 61/871,207 filed on Aug. 28, 2013, and U.S. Provisional Patent Application No. 61/974,399 filed on Apr. 2, 2014, each of which is incorporated by reference in its entirety as if set out fully herein.
- This disclosure relates generally to waterproof housings for mobile electronic devices and waterproof adapters for connecting accessory devices to the mobile electronic devices encased within the waterproof housings while not compromising the waterproof nature of the housings.
- Mobile electronic devices, such as smartphones, portable media players, personal computers, e-readers, tablet computers, and digital audio players, are becoming increasingly important in peoples' day-to-day lives. People rely on mobile electronic devices to communicate with others, engage in commerce, listen to music, watch videos, and manage personal calendars, just to name a few. Due to the high cost of mobile electronic devices, there is a strong incentive to protect these devices from physical damage. Protective cases are readily available, but most of these cases are designed to simply protect electronic devices from drop and crush-induced damage and do not provide sufficient protection against liquid intrusion. For cases that protect against liquid intrusion, connection of a corded accessory device, such as corded headphones or fitness sensors, typically requires opening a port door on the case, which creates an opening for liquid intrusion and renders the case no longer waterproof.
- In one aspect, an accessory connector is configured to provide a liquid-tight seal when inserted into a connector aperture of a waterproof housing for a mobile electronic device. The accessory connector includes a connector extending from a body of the accessory connector, the body configured to allow a user to grasp the accessory connector during insertion or removal of the connector into or from a corresponding connector of the mobile electronic device.

It is therefore desirable to develop an apparatus that prevent liquids from contacting sensitive electrical components while also not interfering with the functionality or usability of the mobile device. A wide variety of protective cases are available for mobile devices, but most fail to provide sufficient protection against liquid intrusion. Those cases that do protect against liquid intrusion typically fail to remain waterproof when a user accesses a physical feature of the electronic device. For example, if a user wants to listen to music through headphones while jogging, the user must open an access port on the case and insert a headphone plug into a headphone jack (i.e. a physical feature) of the mobile device. The access port on the case remains open while headphone plug is connected to the headphone jack in the electronic device. As a result, the case is not waterproof during this period of time, and the electronic device is susceptible to liquid intrusion from, for example, rain while the user is jogging. To avoid this outcome, it is desirable to develop an apparatus that enables the case to remain waterproof even when the user is accessing certain physical features of the electronic device, such as a headphone jack or other electrical connector, when the electronic device is housed within the case.
- A waterproof or water-
resistant housing 60, as shown inFIGS. 8A-B , can be configured to encase and protect a mobileelectronic device 70 from liquid intrusion. Thehousing 60 can include anaperture 40 that allows a user to access a feature (e.g. jack, switch, fingerprint scanner, or touchscreen) associated with the mobileelectronic device 70 while the device remains encased in and protected by the housing. Through theaperture 40 in thehousing 60, the user can connect an accessory device (e.g. headphones, microphone, speaker, battery charger, external data storage device, auxiliary antenna, global positioning system (GPS), heart rate sensor, cadence sensor, etc.) to a jack 72 (e.g. female connector) in the mobile electronic device (see, e.g.FIG. 8B ). In certain instances, a liquid-tight seal can be formed by coupling an accessory connector (e.g. theaccessory connector 9 shown inFIGS. 1 and 7 ) associated with the accessory device to thehousing 60. In other instances, a liquid-tight seal can be formed by inserting a port-sealing bung (e.g. the port-sealingbung 25 shown inFIG. 2 or 5 ) into theaperture 40. - As illustrated in
FIG. 1 , an accessory device, such as those mentioned above, can include anaccessory connector 9 that permits the accessory device to be electrically connected to the mobileelectronic device 70. In one example, theaccessory connector 9 can include ajack plug 10 extending from abody 13. Thebody 13 of the accessory connector can include one or more grasping features (e.g. ridges, knurls, depressions, rubber coating, etc.) that permit a user to easily grasp the accessory connector with their fingers during insertion and removal of the accessory connector. Theaccessory connector 9 can also include a threadedfeature 12 and ajack plug gasket 11. Thejack plug gasket 11 can be an O-ring or other suitable sealing component. Theaccessory connector 9, by way of the threadedfeature 12 andjack plug gasket 11, can be configured to provide a liquid-tight seal between the accessory connector and aconnector aperture 40 in the housing 60 (see, e.g.,FIG. 2 ), thereby preventing water from entering an interior volume of the housing and damaging sensitive components within the mobile electronic device stored therein. - In some examples, the
accessory connector 9 can include a threaded feature 12 (see, e.g.,FIG. 1 ) to permit the accessory connector to removably engage thehousing 60, and in other examples, theaccessory connector 9 can include cam feature (see, e.g.,FIG. 3 ) to permit the accessory connector to removably engage thehousing 60. Where theaccessory connector 9 includes a threadedfeature 12 or cam feature (such as a bayonet-style locking mechanism), a corresponding threaded feature or cam feature can be included in theconnector aperture 40 of the housing 60 (see, e.g.,FIGS. 4A, 4B, and 5 ). The cam feature shown inFIG. 3 can allow theaccessory connector 9 to quickly and easily engage thehousing 1, thereby providing greater ease of use than a threaded connection. - The
jack plug 10 of theaccessory connector 9 can include an electronic device interface. In some embodiments, as shown inFIG. 1 , thejack plug 10 can be configured to transmit electrical signals, such as audio signals. In some embodiments, thejack plug 10 can include a headphone connector, such as a TS, TRS, or TRRS connector. In some embodiments, thejack plug 10 may be configured to transmit optical signals and may include an EIAJ optical connection (e.g., TOSLINK). In some embodiments, thejack plug 10 may be configured to transmit a combination of electrical and optical data signals. Theaccessory connector 9 can be configured to pass through aconnector aperture 40 of ahousing 60 so as to associate with an encasedelectronic device 70, and also to associate with one or more features within theconnector aperture 40 of thehousing 60 in such a manner as to establish a liquid-tight seal therewith. In this instance, theaccessory connector 9 can include an attachment mechanism that includes a threadedfeature 12. In other embodiments, the attachment mechanism can be a bayonet-style mounting mechanism as shown inFIGS. 3 and 4 . -
FIG. 1 provides a perspective view of a portion of anaccessory connector 9 for an accessory device, such as a set of headphones. Theaccessory connector 9 can include ajack plug 10 and ajack plug gasket 11 installed on or affixed to the jack plug. Theaccessory connector 9 can be configured to provide a liquid-tight seal between the accessory connector and aconnector aperture 40 of ahousing 60 for a mobile electronic device. Thejack plug gasket 11 can be located against a gasket seating surface associated with thebody 13 of theaccessory connector 9. Theaccessory connector 9 can include a threadedfeature 12 located between thejack plug 10 and thejack plug gasket 11. Theaccessory connector 9 can be configured to pass through theconnector aperture 40 of thehousing 60 so as to associate with an electronic device removably encased within the housing. Theaccessory connector 9 can be configured to associate with theconnector aperture 40 of thehousing 60 in such a manner as to establish a liquid-tight seal therewith. In this instance, theaccessory connector 9 includes a threadedfeature 12, which is configured to interface with a corresponding threaded feature of theconnector aperture 40. -
FIG. 2 provides a side cutaway view of a threadedconnector aperture 40 into which a threaded port-sealingbung 25 or threaded accessory connector 9 (seeFIG. 1 ) may be threaded. InFIG. 2 , the threaded port-sealingbung 25 is installed in theconnector aperture 40 to prevent entry of liquids, dust, or debris into thehousing 60 when anaccessory device 9 is not occupying theconnector aperture 40. For example, if a user has disconnected her headphones from the mobile electronic device, the user can install the threaded port-sealingbung 25 into theconnector aperture 40 to prevent entry of liquids, dust, or debris into thehousing 60. Theport sealing bung 25 can include abung gasket 36 which enhances the liquid-tight seal. - In order for the
jack plug 10 of theaccessory connector 9 shown inFIG. 1 to be inserted into theconnector aperture 40 of thehousing 60 ofFIG. 2 , the port-sealingbung 25 is unscrewed from theconnector aperture 40. The threadedfeature 12 of theaccessory connector 9 can then be screwed into a corresponding threaded feature of theconnector aperture 40. To avoid losing or misplacing the port-sealingbung 25 while it is removed from theconnector aperture 40, the port-sealingbung 25 can include a tether that attaches to thehousing 1, similar to thetether 910 shown inFIG. 9 . -
FIG. 3 provides a side view of an embodiment of anaccessory connector 9 with ajack plug 30 and a bayonet-style mounting feature 32. Theaccessory connector 9 can include ajack plug gasket 31 that can be any suitable removable gasket (e.g. an O-ring) or non-removable gasket (e.g. a formed-in-place gasket associated with a body of the accessory connector). Theaccessory connector 9 can include one or more cam features 33 a-d (33 d not visible inFIG. 3 ) extending radially from the accessory connector. In some embodiments, one, two, three, four, five, or more cam features may extend radially from theaccessory connector 9. Where the accessory connector includes cam features, such as 33 a-d, corresponding cam receiving features 43 a-d can be included in theconnector aperture 40 of the housing, as shown inFIGS. 4A and 4B . Thejack plug 30 of the accessory connector shown inFIG. 3 is configured to pass through theconnector aperture 40 of the encasement or housing so as to associate with a jack in an encased electronic device. As shown inFIG. 3 , the accessory connector can include cam features 33 a-d that are adapted to engage corresponding cam receiving features 43 a-b (seeFIGS. 4A and 4B ) of theconnector aperture 40 of thehousing 60 so as to establish a liquid-tight seal with the aid of thejack plug gasket 31. -
FIG. 4A provides a close-up perspective view of a portion of ahousing 60 with aconnector aperture 40 having bayonet-style mounting features disposed within the connector aperture. Theconnector aperture 40 can include cam receiving features (e.g. 43 a, 43 b) disposed within the wall of the connector aperture. Theconnector aperture 40 can be adapted to receive either a bung (see, e.g., port-sealingbung 35 shown inFIG. 5 ) or an accessory connector (see, e.g., accessory connector shown inFIG. 3 ) with bayonet-style mounting features (e.g. 33 a-d). -
FIG. 4B depicts a cutaway view of aconnector aperture 40 with bayonet-style mounting features 43 a and 43 b and disposed within the wall of the connector aperture. In some embodiments, theconnector aperture 40 includes only a bayonet-style mounting feature and not a threaded feature, as shown inFIG. 4A . When a port-sealingbung 35 oraccessory connector 9 is received within theconnector aperture 40, a liquid-tight seal is established due to compression of a gasket (e.g. 26) against a gasket seating surface, as shown inFIG. 5 . -
FIG. 5 provides a side cutaway view of ahousing 60 with aconnector aperture 40 having a bayonet-style mounting feature with a port-sealingbung 35 installed in theconnector aperture 40. When the port-sealingbung 35 is installed into theconnector aperture 40, thegasket 26 is compressed between a first gasket seating surface located on the bung and a second gasket seating surface located within the connector aperture, thereby forming a liquid-tight seal between the bung and thehousing 1. - Another configuration of a waterproof linkage for a data connector includes a linkage that is pressed directly into a receiving feature or port of an encasement or housing without requiring rotation to facilitate coupling (in contrast to the threaded connection shown in
FIG. 2 or the bayonet style connection ofFIG. 5 ). The waterproof adapter described herein can be molded directly to theaccessory connector 9, or it can be configured as a separate waterproof adapter component (see, e.g.FIGS. 6A-6C ) that includes threads, cam features, or other attachment features that allow the adapter to be attached to or installed on the accessory connector in a waterproof manner (see, e.g.FIG. 7B ). - In certain instances, it can be desirable to have a quick-connect feature that allows the
accessory connector 9 to form a liquid-tight seal against thehousing 60 without having to thread or twist the accessory connector into theconnector aperture 40, thereby simplifying installation for a user. For instance, it can be desirable to have a quick-connect feature that allows theaccessory connector 9 to be pressed into theconnector aperture 40 with a single motion, thereby simplifying and speeding the connection process and reducing the likelihood of a partial installation. To achieve this outcome, theconnector aperture 40 can be configured to receive a waterproof adapter 50 (seeFIGS. 6A-C ) that attaches to theaccessory connector 9, as shown inFIG. 7B .FIG. 8A shows an example of a portion of a housing having aconnector aperture 40 prior to installation of theaccessory connector 9 with a quick-connect feature, andFIG. 8B shows an example of a portion of a housing having aconnector aperture 40 after installation of anaccessory connector 9 with a quick-connect feature. -
FIGS. 6A-C depict several views of awaterproof adapter 50 in the form of a threaded waterproof adapter.FIG. 6A shows a bottom perspective view of awaterproof adapter 50. In one example, thewaterproof adapter 50 can have a body 59 with a hollow cylindrical or barrel shape. Thewaterproof adapter 50 can have anexterior gasket channel 51 located on an outer circumference of the body 59 at or near a middle region of the body. Thegasket channel 51 can be configured to receive a gasket orseal 52, such as an O-ring, as shown inFIG. 8B (FIGS. 6A-6C show thewaterproof adapter 50 prior to installation of the gasket of seal 52). The bottom side of thewaterproof adapter 50 can include a perimeter, and the perimeter can include one, two, three, four, or more tension tabs (53 a-d) extending therefrom. In one example shown inFIG. 6A , the perimeter of the bottom side of thewaterproof adapter 50 can include four tension tabs (53 a-d) extending therefrom. Each tension tab (53 a-d) can have a lip portion (54 a-d) extending outward radially (e.g. flaring outward) from the tension tab (i.e. extending outwardly from acenterline axis 100, as shown inFIGS. 6A-C and 8B). In other embodiments, the number of tension tabs may be two, three, five, or more. The lip portions (54 a-d) can project outwardly at a predefined angle from the tension tabs (53 a-d) and can be configured such that thewaterproof adapter 50 may be inserted into aconnector aperture 40 of thehousing 60 and can be removably secured therein, as shown in the side cutaway view ofFIG. 8B . The tension tabs (53 a-d) and lip portions (54 a-d) enable the waterproof adapter to function as a quick-connect style connector that is affordable and replaceable and can be sterilized (e.g. to permit use in hospital environments). - The lip portions (54 a-d) can project outwardly from the tension tabs (53 a-d) at any suitable angle. In one example shown in
FIG. 6C , the lip portions (54 a-d) can project outwardly from their respective tension tabs (53 a-d) at an angle of about 45 degrees relative to thecenterline axis 100 of thewaterproof adapter 50. Depending on considerations relating to ease of insertion, ease of removal, and protection against inadvertent removal, the lip portions (54 a-d) can project outwardly from the tension tabs (53 a-d) at other suitable angles, such as about 1-15, 15-30, 1-60, 15-60, 15-45, or 30-45 degrees, relative to thecenterline axis 100 of thewaterproof adapter 50. The lip portions (54 a-d) of the tension tabs (53 a-d) can have rounded end portions, as shown inFIG. 6C , to ease insertion and removal of thewaterproof adapter 50 into theconnector aperture 40 of thehousing 60. By having smooth, rounded end portions on the lip portions (54 a-d) of the tension tabs (53 a-d), damage (such as gouges, scratches, or other forms of wear) to inner surfaces of theconnection aperture 40 can be reduced or avoided during insertion and removal of theaccessory connector 9 to and from, respectively, the connector aperture. Reducing or avoiding damage, such as gouges or scratches, to the inner surface of theconnector aperture 40 is desirable, since it ensures the gasket or seal 52 of thewaterproof adapter 50 is not abraded during an insertion or removal step thereby promoting the gasket or seal's longevity and also ensuring the gasket or seal is placed in contact with a reliable sealing surface to form a liquid-tight seal when inserted into the connector aperture. - During insertion of the
waterproof adapter 50 into theconnector aperture 40, the lip portions (54 a-d) and tension tabs (53 a-d) can deflect inward (slightly) toward thecenterline axis 100 of the waterproof adapter. Once inserted, the lip portions (54 a-d) can exert an outward force against an inner surface of theconnector aperture 40 or, alternatively, a channel or protrusion within the connector aperture or an interior surface of the housing 60 (seeFIG. 8 ). The outward force applied by the lip portions (54 a-d) can result from the lip portions and tension tabs (53 a-d) attempting to resume their original shapes that existed prior to being deflected inwardly as a result of insertion of thewaterproof adapter 50 into theconnector aperture 40. Thewaterproof adapter 50 can have an outer diameter that is slightly smaller than a corresponding inner diameter of theconnector aperture 40 to which it mates, thereby establishing an annular gap between the outer surface of thewaterproof adapter 50 and an inner wall of theconnector aperture 40 upon insertion. The exterior gasket 52 (seeFIG. 8B ) can have an outer diameter that is larger than the inner diameter of theconnector aperture 40. Theexterior gasket 52 can fill the annular gap between the outer surface of thewaterproof adapter 50 and the inner wall of theconnector aperture 40. Theexterior gasket 52 can be at least partially compressed against the inner wall of theconnector aperture 40 upon insertion of thewaterproof adapter 50 into theconnector aperture 40, thereby creating a water-tight seal, as shown inFIG. 8B , that prevents liquid from reaching the electronic device through the connector aperture. - Returning to
FIG. 6A , thewaterproof adapter 50 can be hollow, thereby establishing an inner surface that can include a threadedfeature 56. The threadedfeature 56 can allow thewaterproof adapter 50 to be threaded onto (i.e. threadably engaged with) a corresponding threadedfeature 12 of theaccessory connector 9.FIG. 7A shows theaccessory connector 9 prior to installation of thewaterproof adapter 50, andFIG. 7B shows theaccessory connector 9 after installation of the waterproof adapter. -
FIG. 6B depicts a bottom perspective view of thewaterproof adapter 50. Aninterior gasket seat 55 can exist on an inner circumference of thewaterproof adapter 50. Theinterior gasket seat 55 can be configured to press against ajack plug gasket 11 located on theaccessory connector 9 when thewaterproof adapter 50 is threaded onto the accessory connector. Thejack plug gasket 11 provides a water-tight seal between thebody 13 of the accessory connector and thewaterproof adapter 50 when the waterproof adapter is threaded far enough onto the threadedportion 12 of theaccessory connector 9 to sufficiently compress the jack plug gasket between body of the accessory connector and theinterior gasket seat 55 of the waterproof adapter.Waterproof adapter 50 may also include a gasket, in addition to or as an alternative tojack plug gasket 11, for forming a seal betweenwaterproof adapter 50 andaccessory connector 9. - The
waterproof adapter 50 can be removably installed on theaccessory connector 9 or can be permanently or semi-permanently affixed to the accessory connector by any suitable process. In some embodiments, an adhesive (e.g. glue, epoxy, LOCTITE) may be applied to the threads of either threaded feature (12, 56) to secure thewaterproof adapter 50 to theaccessory connector 9. Thewaterproof adapter 50 may also be welded (e.g. ultrasonically welded) to the threadedfeature 12 of theaccessory connector 9. In some embodiments, thewaterproof adapter 50 may not have a threaded feature to permit engagement with theaccessory connector 9 and may instead be adhered, welded, bonded, or otherwise fastened to the accessory connector by any other suitable approach. In some embodiments, thewaterproof adapter 50 may be overmolded onto theaccessory connector 9 or may be formed as part of the accessory connector. For example, thewaterproof adapter 50 can be an integrally formed portion of theaccessory connector 9 created by, for example, an injection molding process wherein the body of the accessory connector and the waterproof adapter are formed as a single component. Thewaterproof adapter 50 can be used with either male or female connectors. For example, if ahousing 60 for mobile electronic device includes a male connector, thewaterproof adapter 50 may be fitted to the body of afemale accessory connector 9, thereby allowing for insertion of the female connector into or through theconnector aperture 40 in thehousing 60 and sealing the connector aperture against liquid and/or dust intrusion. In some embodiments, a male connector associated with thehousing 60 may partially enter theconnector aperture 40. In some embodiments, the mobile electronic device itself may include a male connector positioned proximate aconnector aperture 40 of thehousing 60. In other embodiments, a mobile electronic device housing may be waterproof or water resistant and does not require a separate waterproof or water resistant housing. In such instances, the mobile electronic device may include a male or female connector adapted to receive anaccessory connector 9 with awaterproof adapter 50 as disclosed herein. -
FIG. 6C depicts a side view of thewaterproof adapter 50. The tension tabs (54 a-d) can each include receiving notches 57 a-d (57 c and 57 d are not visible inFIG. 6C ). The receiving notches 57 a-d can be configured to receive corresponding aperture protrusions (e.g. 64 a-b) located on an inner surface of the connector aperture 40 (seeFIG. 8A ). When the aperture protrusions (64 a-b) engage the receiving notches (57 a-d), the engagement of the respective features can resist removal of thewaterproof adapter 50 from theconnector aperture 40. The engagement of the aperture protrusions (64 a-b) with the receiving notches (57 a-d) can provide the user with audible or tactile feedback confirming that installation has been successfully and fully accomplished. An exterior surface of thewaterproof adapter 50 can be shaped to complement the shape of an inner surface of theconnector aperture 40 to provide a suitable fit and/or a distinctive appearance signifying compatibility. Exemplary cross-sectional geometries of thewaterproof adapter 50 can include cylindrical, elliptical, irregular, or polygonal (e.g. triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, nonagonal, decagonal, etc.). -
FIG. 7A shows a perspective view of anaccessory connector 9 having ajack plug 10 and ajack plug gasket 11 located between aconnector body 13 and thejack plug 10. Theaccessory connector 9 can also include a threadedfeature 12 located near thejack plug gasket 11.FIG. 7B shows a perspective view of awaterproof adapter 50 secured to the threadedfeature 12 of theaccessory connector 9. Thewaterproof adapter 50 includes an exterior gasket orseal 52. In one example, theexterior gasket 52 can be an O-ring. Theexterior gasket 52 may be made of a poloxamer or any other suitable polymer (e.g. thermoplastic elastomer) adhered to or overmolded onto theexterior gasket channel 51 located on an outer circumference of the body of thewaterproof adapter 50. When theaccessory connector 9 ofFIG. 7B is installed into theconnector aperture 40 of thehousing 60, theexterior gasket 52 associated with thewaterproof adapter 50 can form a liquid-tight seal against a corresponding gasket seating surface of theconnector aperture 40. - In some embodiments, the threaded feature of the
waterproof adapter 50 may instead be a bayonet-style attachment feature similar to the bayonet-style mounting feature in theconnector aperture 40 depicted inFIGS. 4A-B . The bayonet-style attachment feature may also include one or more cam-receiving features similar to those depicted inFIGS. 4A-B , which correspond to one or more cam features extending radially from the accessory connector (e.g., seeFIG. 3 ). In such embodiments, the bayonet-style attachment feature of thewaterproof adapter 50 can receive a bayonet-style mounting feature of theaccessory connector 9, such as that depicted inFIG. 3 , thereby forming a watertight seal between thewaterproof adapter 50 and the accessory connector. -
FIG. 8A depicts a side cutaway view of ahousing 60 surrounding a mobileelectronic device 70. The mobile electronic device includes afemale connector 72 adapted to receive a male connector. In one example, thefemale connector 72 can be a headphone jack configured to receive ajack plug 10. In another example, thefemale connector 72 can be a charging port, such as a LIGHTNING port or micro-USB port, configured to receive a compatible charging cable or data transfer cable. -
FIG. 8B shows a side cutaway view of a mobileelectronic device 70 encased in ahousing 60. Thehousing 60 can include aconnector aperture 40 configured to receive anaccessory connector 9 having awaterproof adapter 50 attached thereto. Theconnector aperture 40 can includeaperture protrusions lip receiving notch 63 can be located on an inner surface of theconnector aperture 40 and can be adapted to receive one or more lip portions (e.g. 54 a-d) of thewaterproof adapter 50. - As shown in
FIG. 8B , thewaterproof adapter 50 can be secured to theaccessory connector 9, and the accessory connector can be inserted into theconnector aperture 40 of thehousing 60. Theaccessory connector 9 can include ajack plug 10 extending therefrom, and the jack plug can be received by afemale connector 72 located within the encased mobileelectronic device 70. Theaccessory connector 9 can include ajack plug gasket 11 that is configured to provide a liquid-tight barrier when pressed against a gasket seat 55 (seeFIG. 6B ) of thewaterproof adapter 50. In some embodiments, thejack plug gasket 11 may be attached to the waterproof adapter 50 (e.g. resting on, adhered to, or overmolded on thegasket seat 55, which is visible inFIG. 6B ). Anexterior gasket 52, which is located in anexterior gasket channel 51 of thewaterproof adapter 50, can form a water-tight barrier by compressing against the inner wall of theconnector aperture 40. As shown inFIG. 8B ,lip portions housing 60 and either beyond an inner perimeter edge of the connector aperture 40 (see, e.g., the position oflip portion 54 a with respect to the inner perimeter edge of the connector aperture 40) or into alip receiving notch 63 on the interior of the encasement (see, e.g., the position oflip portion 54 c relative to the lip receiving notch 63). In some embodiments, thehousing 60 may include only alip receiving notch 63. In certain embodiments, thelip receiving notch 63 may be located on an inner surface of theconnector aperture 40. - Receiving notches (e.g. 57 c) in the
waterproof adapter 50 can be configured to receive a corresponding aperture protrusion (e.g. 64 b). Physical engagement between the lip portions (e.g. 54 a-d) of thewaterproof adapter 50 and the lip receiving notches (e.g. 63 b) of the adapter resists accidental removal of theaccessory connector 9 andwaterproof adapter 50 from theconnector aperture 40. Similarly, physical engagement between the aperture protrusions (e.g. 64 a, 64 b) and the receiving notches (e.g. 57 c) of thewaterproof adapter 50 resists inadvertent removal of theaccessory connector 9 andwaterproof adapter 50 from theconnector aperture 40. -
FIG. 9 shows a front view of ahousing 60 for a mobile electronic device. Thehousing 60 can have a port 40 (i.e. connector aperture) in one of its external surfaces and a port-sealingbung 905 designed to seal the port by providing a liquid-tight seal therewith. The port-sealingbung 905 can be attached to thehousing 60 by atether 910.FIG. 10 shows a close-up top perspective view of a portion of thehousing 60 ofFIG. 9 showing theport 40 and port-sealingbung 905 in greater detail. Thetether 910 can be a flexible portion that connects the port-sealingbung 905 permanently, semi-permanently, or removably to thehousing 60. Thetether 910 can be made of an elastomer, metal, fabric, or any other suitable material that can withstand exposure to liquids. In one example, the port-sealingbung 905 can have a body with a cylindrical or barrel shape. The port-sealingbung 905 can have anexterior gasket channel 951 located proximate an outer circumference of the body at or near a middle region of the body. Thegasket channel 951 can be configured to receive a gasket or seal, such as an O-ring (the port-sealingbung 905 inFIG. 10 is shown prior to installation of the gasket or seal). The bottom end of the port-sealingbung 905 can include a perimeter, and the perimeter can include one, two, three, four, or more tension tabs (953 a-d) extending therefrom. In one example shown inFIG. 10 , the perimeter can include four tension tabs (953 a-d) extending therefrom. Each tension tab (953 a-d) can have a lip portion (e.g. 954 b, 954 d) extending outward radially (e.g. flaring outward) from the tension tab (i.e. extending outwardly from a centerline axis if the port-sealing bung). In other embodiments, the number of tension tabs may be two, three, five, six or more. The lip portions (954 a-d) can project outwardly at a predefined angle from the tension tabs (953 a-d) and can be configured such that the port-sealingbung 905 can be removably installed into theport 40 of thehousing 60. In one example shown inFIG. 10 , the lip portions (954 a-d) can project outwardly from their respective tension tabs (953 a-d) at an angle of about 45 degrees relative to acenterline axis 100 of the port-sealingbung 905. Depending on considerations relating to ease of insertion, ease of removal, and protection against inadvertent removal, the lip portions (954 a-d) can project outwardly from the tension tabs (953 a-d) at other suitable angles, such as about 1-15, 15-30, 1-60, 15-60, 15-45, or 30-45 degrees, relative to the centerline axis of theport sealing bung 905. - To ensure that water is unable to reach the mobile electronic device and cause damage to the mobile electronic device, it can be desirable for the port-sealing
bung 905 to be firmly installed in theconnector aperture 40. In one example, the port-sealingbung 905 may require a tool to uninstall the port-sealingbung 905 from theport 40. In one example, an extraction force of at least 15 newtons may need to be applied to the port-sealingbung 905 to uninstall the port-sealing bung from theport 40, where the extraction force is measured as a vector aligned with the centerline axis of the body of the port-sealing bung and directed away from theport 40. In another instance, an extraction force of at least 20 newtons may need to be applied to the port-sealingbung 905 to uninstall the port-sealing bung from theport 40, where the extraction force is measured as a vector aligned with the centerline axis of the body of the port-sealing bung and directed away from theport 40. - As shown in
FIG. 9 , thehousing 60 can have a port (i.e. connector aperture) located in one of its external surfaces and a hingeddoor 920 designed to seal the port by providing a liquid-tight seal therewith.FIG. 9 shows the hingeddoor 920 in an opened position, exposing a sealing material disposed on an inner surface of the hinged door. The sealing material disposed on the hingeddoor 920 is represented by shading inFIG. 9 . The hingeddoor 920 can provide access to an electrical connection, such as a charging port or data port of the mobile electronic device. The hingeddoor 920 can be attached to thehousing 60 by any suitable hinged mechanism. To ensure that water is unable to reach the mobile electronic device and cause damage to the mobile electronic device, it can be desirable for the hingeddoor 920 to be firmly installed over the port when in the hinged door is in a closed position. In some examples, a tool may be required to open the hingeddoor 920 to expose the port in thehousing 60. In one instance, an extraction force of at least 15 newtons may need to be applied to the hingeddoor 920 to expose the port in thehousing 60, where the extraction force is measured as a vector aligned with a centerline axis of the port and directed away from the port. In another instance, an extraction force of at least 20 newtons may need to be applied to the hingeddoor 920 to expose the port in thehousing 60, where the extraction force is measured as a vector aligned with a centerline axis of the port and directed away from the port. The necessary extraction force can be controlled by the magnitude of the interference fit between a locking feature of the hingeddoor 920 and a receiving feature located on thehousing 60, where the locking feature of the hinged door is designed to produce an interference fit with the receiving feature when the hinged door is in a closed position. In some instances, the hingeddoor 920 may be removable from thehousing 60 to permit replacement of the hinged door with a replacement hinged door that is easier or more difficult to transition from a closed position to an opened position to allow the housing to be modified to suit an intended use. For example, if thehousing 60 will be used by an employee at a waterpark where the housing is frequently exposed to water and potential drops, the risk of water damage to the mobile electronic device is relatively high, so it can be desirable to install a hingeddoor 920 that is more difficult to open to reduce the risk of the hinged door inadvertently opening during use in a wet environment. - An
accessory connector 9 for an accessory device can be configured to provide a liquid-tight seal when inserted into aconnector aperture 40 of awaterproof housing 60 for a mobile electronic device. Theaccessory connector 9 can include amale connector 30 extending from abody 13 of the accessory connector. Thebody 13 can be configured to allow a user to grasp theaccessory connector 9 during insertion or removal of themale connector 30 into or from, respectively, a female connector (see, e.g.,female connector 72 ofFIG. 8B ) of the mobile electronic device. Theaccessory connector 9 can include agasket 31 installed against a gasket seating surface 14 of thebody 13. Thegasket 31 can be configured to provide a liquid-tight seal against agasket seating surface 41 of theconnector aperture 40 of thewaterproof housing 60 when the accessory connector is installed into theconnector aperture 40. Theaccessory connector 9 can include afirst cam feature 33 a extending outwardly from the accessory connector. Thefirst cam feature 33 a can be configured to engage a firstcam receiving feature 43 a within theconnector aperture 40 of awaterproof housing 60 when the accessory connector is installed into the connector aperture. The accessory connector can include asecond cam feature 33 b extending outwardly from theaccessory connector 9. Thesecond cam feature 33 b can be configured to engage a secondcam receiving feature 43 b within theconnector aperture 40 of the waterproof housing when the accessory connector is installed into the connector aperture. Thesecond cam feature 43 b can extend radially from acenterline axis 100 of the accessory connector in a direction that is aligned with and opposite to the direction in which thefirst cam feature 43 a extends radially from the centerline axis. In one example, thegasket 31 can be an O-ring. In some examples, themale connector 30 can be a jack plug or a micro-USB connector. Theaccessory connector 9 can be configured to transfer power or data. Theaccessory connector 9 can be configured to transfer electrical or optical signals. - A
waterproof adapter 50 can be configured to provide a liquid-tight seal between awaterproof housing 60 for a mobileelectronic device 70 and anaccessory connector 9 of an accessory device. Thewaterproof adapter 50 can include a body 59 having an exterior surface and a hole passing through acenterline axis 100 of the body as shown inFIGS. 6A-6C . The hole can define an interior surface of the body 59 of the waterproof adapter. Thewaterproof adapter 50 can include two or more tension tabs (e.g. 53 a, 53 b) extending from a first end of the body 59. Each tension tab can include a lip portion (e.g. 54 a, 54 b) that extends outwardly relative to thecenterline axis 100 of the body 59. Thewaterproof adapter 50 can include anexterior gasket channel 51 on the exterior surface of the body 59. Theexterior gasket channel 51 can circumscribe the exterior surface of the body 59. Thewaterproof adapter 50 can include anexterior gasket 52 disposed at least partially within theexterior gasket channel 51 on the exterior surface of the body 59, as shown inFIG. 8B . Thewaterproof adapter 50 can include aninterior gasket seat 55 proximate the interior surface of the body. The waterproof adapter can include a first attachment feature on the interior surface of the body 59. The first attachment feature can be configured to attach to a second attachment feature on an accessory connector of an accessory device to form a liquid-tight seal between a jack plug gasket on the accessory connector and the interior gasket seat of the body. In one example, the attachment feature on the interior surface of thewaterproof adapter 50 can be a threadedfeature 56. In another example, the attachment feature on the interior surface of thewaterproof adapter 50 can include two or more bayonet-style mounting features. Each tension tab (e.g. 53 a, 53 b) of thewaterproof adapter 50 can include a receiving notch (e.g. 57 a, 57 b) proximate each lip portion (e.g. 54 a, 54 b), as shown inFIG. 6C . Each receiving notch (e.g. 57 a, 57 b) can be configured to receive an aperture protrusion (e.g. 64 a, 64 b) extending from an inner surface of aconnector aperture 40 of thewaterproof housing 60 for the mobileelectronic device 70. Each lip portion (e.g. 54 c) can be configured to associate with a lip receiving notch (e.g. 63) in aconnection aperture 40 of thewaterproof housing 60, as shown inFIG. 8B . In some examples, theexterior gasket 52 disposed within theexterior gasket channel 51 on the exterior surface of the body 59 of the waterproof adapter can be an O-ring. - A waterproof case for a mobile
electronic device 70 can include ahousing 60 that is adapted to cover at least a portion of the mobile electronic device. The mobileelectronic device 70 can include an electrical or optical connector (e.g. 72) that is accessible proximate an external surface of the mobile electronic device. The waterproof case can include aconnector aperture 40 extending through thehousing 60. Theconnector aperture 40 can provide access to the mobileelectronic device 70 encased in thehousing 60. Theconnector aperture 40 can be located proximate the electrical or optical connector (e.g. 72) of the mobileelectronic device 70 when the mobile electronic device is installed in thehousing 60. A port-sealingbung 905 can be attached to thehousing 60 by atether 910, as shown inFIG. 10 . The port-sealingbung 905 can be adapted to fit within theconnector aperture 40 to provide a liquid-tight seal therewith. The port-sealingbung 905 can have a body having an exterior surface and two or more tension tabs (e.g. 953 a, 953 b) extending from a first end of the body. Each tension tab can include a lip portion (e.g. 954 a, 954 b) extending outwardly relative to a centerline axis of the body. The port-sealingbung 905 can include anexterior gasket channel 951 proximate the exterior surface of the body. Theexterior gasket channel 951 can circumscribe the exterior surface of the body. An exterior gasket can be disposed at least partially within theexterior gasket channel 951 on the exterior surface of the body. The exterior gasket can be adapted to form a liquid-tight seal between the port-sealingbung 905 and an inner surface of theconnector aperture 40 when the port-sealing bung is inserted into the connector aperture. Each tension tab can include a receiving notch configured to receive an aperture protrusion extending from the inner surface of theconnector aperture 40 of thewaterproof housing 60 when the port-sealing bung is installed in the connector aperture. Theconnector aperture 40 can include two or more lip receiving notches, and each lip receiving notch can be adapted to receive one or more of the lip portions of the port-sealingbung 905 when the port-sealing bung is inserted into theconnector aperture 40. In some instances, a tool may be required to remove the port-sealingbung 905 from the connector aperture to avoid inadvertently uninstalling the port-sealing bung from the connector aperture during use of the waterproof case. Ensuring that the port-sealingbung 905 does not inadvertently come free of theconnector aperture 40 during use is very important in certain applications, such as when using the protective case in the presence of flammable or explosive fumes or gases, such as on an offshore oil platform. In such an application, it can be critical for the case to completely contain any sparks that may occur within the electronic device as a result of static electricity or from ordinary operation. To ensure containment of any sparks within the electronic device, it is essential that the port-sealingbung 905 remain firmly in place within theconnector aperture 40 during use. In some examples, when the port-sealingbung 905 is installed in theconnector aperture 40, an extraction force of at least 15 newtons may need to be applied to the port-sealing bung to uninstall the port-sealing bung from the connector aperture, where the extraction force is aligned with thecenterline axis 100 of the body of the port-sealing bung. - An
