This disclosure relates generally to sockets and ports (e.g., SD card sockets, micro-SD card sockets, communication ports, or other sockets or ports in consumer electronics), or slots, of electronic devices and, more specifically, to memory card sockets, USB ports that will withstand exposure to moisture, liquids, corrosive materials, including, but not limited to, water.
Currently, the electrical contacts in memory card sockets (e.g., SD card sockets, micro-SD card sockets, or other removable card sockets or receptacles) are quick to corrode and fail when exposed to water, water vapor or high humidity (e.g., from long-term exposure to moisture, from current leakage when moisture is present, from corrosive liquids or other corrosive elements). Existing solutions are focused on prevent moisture from penetrating into the volume (i.e., the interior) of the electronic device of which the memory card socket is a part.
In the industry companies and manufacturers have attempted to prevent the entry of moisture into the device by mechanical seals and O-rings. Some solutions include removable rubber plugs that may be placed into ports or sockets to prevent the ingress of moisture. As used herein, the term “moisture” includes, but is not limited to, water, water vapor and/or humidity, as well as other aqueous and non-aqueous liquids.
The following disclosure may allow the practice of using replicate memory cards to protect the electrical contacts during coating of electronics in a chemical vapor deposition (CVD) or atomic layer deposition (ALD) or other deposition process wherein a coating is placed on a printed circuit board (PCB) or other electronic to render it substantially moisture-resistant. In addition, the embodiments herein may eliminate the exposure of electrical contacts or connections to environmental exposure when the cards are locked into place. The concepts may also prevent electrical contact erosion due to current leakage and the function will be transparent to the user. It will be appreciated that the embodiments disclosed herein may be applied and adapted to fit all memory cards or all sizes including NANO cards.
Multiple embodiments or techniques may be used to prevent moisture from penetrating the interior of the electronic device. In the case of a socket, the socket may include a base and a cover wherein the base may be configured to receive a memory card, SIM card or other removable electronic card or the like. The cover of the socket may be hingedly associated with the base. A sealing element, such as an O-ring, may be configured to create a seal with the base of the socket as the cover is positioned and held in place (e.g., by way of a latch, a snap or other reversibly engaging means) against the base. Thus, when the cover is closed, the cover, the sealing element and the base may seal the receptacle and its contents (e.g., a memory card, the contacts of a memory card, SIM card, SIM card contacts, or other electrical card or medium for transferring power, data or information) from external moisture. In some embodiments, such as that depicted by the images that follow, the O-ring may be carried by the cover. In other embodiments, the O-ring may be carried by the base (e.g., by the lower surface of the receptacle, or other engaging means with the receptacle or socket).
With regard to a port according to this disclosure, which may comprise any suitable type of communication port (e.g., a micro-USB port, a port with a proprietary configuration (e.g., a LIGHTNING port of an electronic device available from Apple, Inc.), or other port(s) known in the art), is configured to withstand exposure to moisture.
The disclosed communication port includes a design that prevents electrodes, or contacts within the communication port from being exposed to moisture. The design may be integral to the port, and may be configured to prevent exposure of the contacts to moisture without any action or input from the user (i.e., the user does not need to remember to reinsert a rubber plug or take any action). Further, the disclosed communication port may lack any feature that prevents moisture from entering into the port; it may merely be configured to prevent moisture from contacting the electrodes, or contacts, within the port.
In a specific embodiment, a communications port provides a seal against intrusion of moisture or other contaminants into the electrical device. The communication port includes a cover member that protects an electrical contact when no connector is present within a socket of a communication port. In some embodiments, the cover member comprises a soft, pliable material, which may also be compressible and resilient. In some embodiments, the cover member is fabricated from a rigid material and includes a resilient seal that engages the electrical contact against intrusion of a contaminant. When a connector is introduced into the socket, the connector may displace the cover member and, in some embodiments, compress and/or displace the cover member. Displacement of the cover member may reveal the contacts, and may compress the cover member and/or one or more springs located behind the cover member. In embodiments where the cover member comprises a resilient material, the cover member may resiliently return to is protective position over the contacts when the connector is removed from the socket. Removal of the connector from the socket may also remove a compressive force on any springs behind the cover member, which may enable the springs to move, or bias, the cover member back to its original position (i.e., over the contact(s)).
Other aspects, as well as features and advantages of various aspects, of the disclosed subject matter will be apparent to those of ordinary skill in the art through consideration of this disclosure and the appended claims.

With reference to
The base may further include a window 24 and connectors 26, or contacts. Wherein the window 24 may allow for the connectors 26 to engage the card 30. The base may further include rails 28 or guides which extend superiorly from the base 12. The rails 28 may include a lip 32 extending at least partially medially (or toward the middle) and parallel with a top surface of the base 12. The lip 32 may be configured to hold a card 30 in place by sliding the card 30 along the rails 28 underneath the lip 32. The card 30 may only slide to a pre-determined location on the base 12 because of a stop 34 on a first end 33 of the base 10. A second end 35 of the base 12 may be the end wherein the card 30 is inserted along the rails 28. Each of the rails 28, lip(s) 32, the window 24, and stop 34 may define the receptacle 13.
The cover 14 may include a void 36 on a bottom side 38 of the cover 14. The void 36 is positioned such that it “covers” at least a portion of the top side of the base 12, the void allowing space for the card 30 to sit on the base 12 with the cover 14 covering the card 30 in its entirety. The bottom side 38 of the cover also includes a circumferential cut out that may pressedly fit an O-ring 42, or rubber ring, or the O-ring 42 may be integral to the cover 14. The O-ring 42 may engage the base 12 when the socket 10 is in a closed configuration creating a moisture-tight seal around the entire card 30. In some embodiments, the O-ring is designed to surround the card 30 without touching the card, e.g., by encompassing a greater area than the card 30. A top surface 44 of the cover 14 may include a latch engaging portion 46 opposite the hinge side 19 of the cover 14. The latch engaging portion 46 may be a step down from the top surface 44 of the cover 14 and is configured to receive a portion of the latch 22 when the socket 10 is in a closed configuration.
The connectors 26 are able to contact the card 30 through the window 24. Thus allowing a connection to be made to an electronic device that engages the socket 10.
An exterior of the base 12 of the socket 10 may be sealed. The base 12 may include an exterior seal. Alternatively, the base 12 may be sealed against a printed circuit board (PCB) of an electronic device of which the socket 10 is a part. Sealing of the base 12 against the PCB may prevent the base 12, contacts 26 of the socket 10 and contents of the receptacle of the base 12 from being exposed to moisture.
It will be appreciated that the card 30 may also engage the base through a press-fit, snap-fit, spring-fit or other means known in the art for engaging and maintaining a device in a specific configuration. It will further be appreciated that the aforementioned embodiment is modular and each of the pieces may be interchanged with other pieces to create a moisture-tight seal for the card 30.
A separate embodiment of a socket is illustrated in
The socket 110 may include rails 120 or guides toward the proximal section 112 that extend superiorly from a top surface of the socket 110 and each rail 120 may include a lip 122 that extends medially (or toward the middle) toward the center line of the socket 110 and parallel to the top surface of the socket 110. The rails 120 may extend from a proximal end longitudinally along the body of the socket toward the distal section 114. The rails 120 may terminate prior to reaching a distal end or may extend the entire length of the socket 110. The lip 122 and rails 120 may hold the card 130 secure to the body of the socket 110 disallowing movement of the card 130 in a lateral direction. Furthermore a clip 124, or latch, or a spring clip, may extend from the proximal end of the socket 110. The clip 124 may secure the card 130 in a longitudinal direction providing that a card 130 may not be removed from the socket 110 unless the clip 124 is pressed by a user in an inferior direction with relation to the card 130, allowing the card 130 to be removed from the socket 110 longitudinally with respect to the socket 110.
A portion of the socket 110 body may have a taller profile in a superior/inferior direction at the location of the receptacle 118. The taller profile at the receptacle 118 may allow for the recesses 126 to extend into the body of the socket 110 and thus allowing for engagement of the O-rings 128. The O-ring 128 may be press-fit within the recess 126 or the O-ring 128 may be integral to the recess 126.
With regard to
These two embodiments are focused on the inclusion of the O-ring style seal between the card and the socket. Actual designs of the socket and contacts and inserts are changeable and interchangeable as may be established by industry practices and standards.
Another possible embodiment, which may be used for a SIM card, a Micro SIM card, is set forth below. With regard to
The base 212 may include a window 224 and contacts 226, or connectors, which may be exposed through the window 224. The window 224 may allow for a contact(s) from the card 230 to interface with the contacts 226 of the base 212. An O-ring 228 may be positioned along a periphery of the window 224, on the cover facing side 232 of the base 212. The O-ring 228 may provide a seal to prevent moisture ingress into the contacts 226 into the window 224 and thus the contacts 226 of the socket and the contact(s) 238 of the card 230. Each of the rails 218, lip(s) 220, the window 224, O-ring 228 and stop 233 may define the receptacle 13.
The base 212 may also include an engagement feature 235, or latch, positioned on the open end 222 of the socket 210. The engagement feature 235 may include two latches, one positioned on each lateral end of the open end 222 of the socket 210. The latches 235 may each include a recess 234 extending toward the center line of the socket 210 and a latch lip 237 extending laterally from a center line of the socket 210. The recess 234 is configured to receive a protrusion(s) 236 from the cover 214. The protrusion(s) 236 may extend from the body of the cover 214. The protrusion(s) 236 may fit into the recess(es) 234 in a snap-fit fashion. The protrusions 236 may overcome the latch lip 237 by a pressing force thus reversibly locking the cover 214 to the base 214. The latch lip 237 prevents release of the cover 214 from the base 212 unless a force is applied by a user to overcome the latch lip 236. It will be appreciated that the bottom-side of the base 212 may include a seal that seals the base against the printed circuit board (PCB) to provide a total seal of the card 230 and contacts 226.
With regard to
With regard to
The cover 214 (shown from the bottom side in the exploded view of
With regard to
The communication port 310 may also include a biasing member, e.g., springs 324, which may be coiled and positioned behind the cover member 320. The springs 324, which may be coiled, behind the cover member 320 and in a somewhat relaxed state, where they push, or bias, the cover member forward, and hold the cover member 320 in place over the contact board 322 (
With regard to
A contact carrier 326, or retainer, includes the contacts 318 which may be insert molded into the carrier 326 body. The contact board 322 may extend toward the socket 315 from end of the carrier 326 opposite the contacts 318. The carrier 326 may include capture posts 328 configured to capture one end of the springs 324 and spring guides 332 on opposite lateral ends of the carrier 316, the spring guides 332 molded into the body of the contact carrier 326. The carrier 326 further includes a tray 329 between the spring guides 332 for receiving at least a portion of the cover member 320.
The cover member 320 may slide as previously disclosed. The cover member 320 may be injection molded and a sealing element 330, which may be adjacent to and engage with the contact board 322, may be deformable and may be over molded or bonded to the cover member 320. The cover member 320 also includes capture posts 328 configured to capture one end of the springs 324, opposite the carrier 326. Spring guides 332 may also be molded into the body of the cover member 320 to maintain the springs in a defined pathway. The cover member may also include a supporting element 334 positioned inferior the contact board 322 to prevent cantilever bending due to sealing forces.
The port body 312 may be manufactured from stamped and folded sheet metal. The port body 312 may encompass the carrier 326 with the cover member 320, the springs 324, the supporting element 334 and the sealing element 330. The port body may include securement flaps 336, or wings or mounting tabs that extend laterally away from the port body 312. The flaps 336 may include holes to allow for securement elements, such as screws or rivets, to pass through and secure the communication port 310 to an electronic device.
When the cover member 320 is displaced with a connector the cover member may slide longitudinally into or onto the tray 329 of the contact carrier 326. The sealing element 330 may also slide into or onto the tray 329 as well. The supporting element 334 of the cover member 320 may slide along an inside wall of the port body 312, again, preventing any bending of the contact board 322.
Assembly of the different elements of the communication port 310 may include placing the cover member 320 tip over a proximal end of the contact board 322; placing the springs 324 within the spring guides 332 and seating each end of the springs 324 to the spring posts 328; compressing the cover member 320 into the contact carrier 326 to fully seat all the components; inserting the assembly into the back of the port body 312 until the tip of the contact board 322 is even with the front end of the port body 320; bending locking tabs of the port body 312 into complementary pockets in the contact carrier 326. It will be appreciated that the assembly may also be inserted from the front as well depending on whether a stop or lip is manufactured on the front end of the port body 312.
The proposed embodiments may prevent moisture ingress into the contacts of the electronic device(s). Alternatively, the concepts herein may allow for coating of an electronic device with a parylene (poly(chloro-p-xylylene) or polyp-xylylene) or others) coating without the need to mask or demask the contacts with a glue, hot melt, tape or other masking elements as set forth in U.S. patent applications Ser. Nos. 13/735,862; 13/737,709; 14/794,713; and 14/157,684 which are herein incorporated by reference. Furthermore it would prevent the need to ablate or remove any coatings like those methods set forth in U.S. patent applications Ser. Nos. 14/157,743 and 14/213,765 which are herein incorporated by reference.
Other aspects, as well as features and advantages of various aspects, of the disclosed subject matter will become apparent to those of ordinary skill in the art through consideration of the preceding disclosure.
