## Background
TECHNICAL FIELD
The disclosure relates generally to securing memory modules and subscriber identity modules (SIMs) in electronic devices, and, more particularly, to an apparatus for securing a memory and/or SIM in an electronic device, wherein an external control of the device hides the memory module and/or SIM.
BACKGROUND
Electronic devices such as cellular phones, tablets, music players, cameras, etc., often need SIMs and/or memory modules. A SIM stores information regarding the user or user account associated with the device. The information on a SIM is used by a communication network to control and configure access by the device to the network. Currently, the most common form factor of a SIM is a card, and thus a SIM is commonly referred to as a SIM card. A SIM card can be transferred between different devices. SIM cards have become more miniaturized over the years. They may come in a variety of sizes, including a full-size SIM 1st form factor (1FF), a mini-SIM 2nd form-factor (2FF), a micro-SIM 3rd form-factor (3FF), and a nano-SIM 4th form-factor (4FF). The 4FF SIM can be put into adapters for use as a 2FF or 3FF SIM, thus making it backward compatible. On some cellular networks, a mobile device is locked to its carrier SIM card, meaning that the device only works with SIM cards from the specific carrier.
Electronic devices may use memory modules to store photos, videos, music, and documents. A commonly used memory module is a Secure Device (SD) card. Types of SD cards include the standard SD, the miniSD, and the microSD (originally named the TransFlash or TF). The microSD (uSD) is smaller than the standard SD and the mini SDS.

DETAILED DESCRIPTION
In accordance with the foregoing, an apparatus for securing memory modules and SIMs in an electronic device will now be described. In an embodiment of the invention, a holding tray carries a SIM and a memory module, multiple memory modules, multiple SIMs, or a combination thereof. The holding tray is secured inside the electronic device. An external control (such as a volume control, a power control, or camera control) of the electronic device is part of, and hides the holding tray. The external control may be configured as, for example, a rocker control, slider or push button. The external control may interact with an internal control of the electronic device, such as a rocker-type switch actuator, button, or slider. When the holding tray is removed from the electronic device, a user may remove SIMs or memory modules from the tray, or place SIMs or memory modules within the tray. The holding tray may be a single tray (e.g., a single SIM or SD card tray) or a multi-module tray (e.g., a dual card inline tray).
According to another embodiment of the invention, the external control is not part of a holding tray, and no holding tray may be present. Instead the external control is a stand-alone structure that can be attached to the external device to hide the memory module and/or SIM, and can be removed from the electronic device to allow access to the memory module or SIM. The memory module or SIM may be held within the electronic device by a push-push connector, in which case the external control hides the memory module or SIM and the push-pull connector.
The apparatus described herein may be designed and arranged to eliminate product entry points, increase usable antenna space, and decrease or prevent the ingress of water and other liquid into the interior and into the electronic circuitry of the electronic device. In many implementations, no additional cover will be required for the memory module or SIM that would impact the cosmetic appearance and overall design of the electronic device.
Moreover, the external control may have a natural protrusion on which a fingernail notch can be cut, which can allow for a tool-less extraction or removal of the memory module or SIM by the user. Of course, the external control may also be one for which a tool is used, such as when the external control is configured to be flush with the exterior surface of the electronic device.
The apparatus described herein may allow for increased printed circuit board area for electronic devices. Moreover, the modular manufacturability of the external control (or external control/tray combination) may allow various colors and cosmetic shapes to be applied to the external control at late stages of production.
In one embodiment, a holding tray assembly comprises: a holding tray, an electronic device having an external control, and a tray-receiving opening for receiving the holding tray. The holding tray can have at least one receiving opening for receiving a SIM or memory module (such as a SIM card or SD card). The holding tray can include an external control disposed on one end of the tray. The external control may be operatively associated with an internal switch that controls various functions of the electronic device (e.g., volume, power, and camera). The holding tray can be moveable from an open position extending outwardly from the electronic device for access to said SIM or memory module to a closed position disposed and positioned in the tray-receiving opening in an interior of said electronic device for substantially preventing access to the SIM or memory module.
Prior to describing further embodiments of the invention, it should be noted that, although the drawings and specific description refer to SIM cards and SD cards (and their variants), the holding tray and push-push connector may be configured to carry SIMs and memory modules having other form factors (e.g., films or blocks).
It is also to be understood that, although the external control shown in the drawings is a rocker-type volume control, the external control may be implemented in a variety of ways, including a power control, or a camera control. Also, in addition to the rocker-type structure shown in the figures, the external control may be implemented as, for example, a button or slider.
For convenient reference, the term “data card” is used to refer to SIM cards, SD cards, and other generally card-shaped data-carrying devices.
Referring to FIGS. 1-4 of the drawings, an embodiment of the invention will now be described. An electronic device system 100 includes an electronic device 102 (which may be implemented as, for example, a smartphone, tablet computer, or music player) can comprise an electronic visual display 104 (FIGS. 1 and 2) for displaying images 106. The electronic visual display can comprise a user interface (UI) 108. The electronic visual display can comprise a screen, such as an impact resistant screen, a display screen, a touchscreen, a screen with an accelerometer, or as any other suitable arrangement. A modular impact-resistant housing 110 can have substantially parallel longitudinal sides 112 and 114, and substantially parallel lateral sides 116 and 117, which can extend between and be connected to the substantially parallel longitudinal sides. The housing can also have a front 118 comprising a generally rectangular frame 120 with a front surface 122 and can have a back 124 with a back surface 125. The frame can be positioned peripherally about and secure the electronic visual display.
As shown in FIGS. 8 and 9, the electronic device can comprise one or more longitudinally spaced electronic switches, including a right switch 126, which increases the level of sound (volume) emitted from the electronic device, and a left switch 127, which decreases and softens the level of sound (volume) emitted from the electronic device.
The housing can have a tray-receiving opening 128 (FIGS. 2 and 4) for receiving an elongated holding tray 130. The tray-receiving opening can be: a slot, notch, fingernail notch, hole, recessed opening, cavity, tool-receiving opening, or any other suitable opening. The holding tray can have at least one card-receiving opening 132, 134 and/ or 136 (FIG. 5) for receiving at least one data card 138 or 140 and card-supporting surfaces 142 that can be positioned adjacent and in proximity to the card-receiving opening(s) for supporting, abuttingly and snugly engaging, and cushioning the data card. The data card receiving opening(s) can be a cavity, a rectangular-card-receiving opening, a cutout, a cutaway, an undercut, a stepped opening, hole, pad, pocket or any other suitable opening. The holding tray can move and slide laterally outwardly at an open position extending outwardly from the electronic devices for access to the data card and subsequently move and slide laterally inwardly to a closed position located in the tray-receiving opening in an interior of the electronic device for substantially preventing access to the data card.
As shown in FIGS. 5 and 6, the holding tray can have substantially parallel elongated sides 144 and 146, and transverse ends providing a back end 148 and a front end 150 that extend longitudinally across and connect the sides about right angles. The corners 152 of the tray can be rounded. The central part of the front end can have an outwardly and laterally extending convex protuberance 154 providing a rounded nose and pivot point. An external control 156 (depicted as an elongated rocker arm) can be pivotally connected to the pivot point by a pivot pin 158. The external control can face outwardly and can have a greater longitudinal span and width than the sides of the tray.
The external control of the holding tray can be operatively connected to the switches for controlling various functions of the electronic device. For example, when implemented as a volume control, the external control may be used to regulate and adjust the loudness and softness of an audible signal and sound emitted from the electronic device. In the illustrated embodiment, the right volume up rocker portion 160 (FIGS. 5 and 6) of the rocker arm can pivot counterclockwise to increase the volume and sound of the electronic device while the left volume down rocker portion 162 of the rocker arm can pivot clockwise to decrease the volume and sound of the electronic device or vice versa.
The external control can have inwardly extending plugs 164 and 166 providing switch actuators (FIGS. 2 and 4-6) which can comprise inwardly facing rectangular or cylindrical plungers that provide electrical contacts. The electronic device can have a pair of longitudinally spaced receptacles 168 and 170 (FIGS. 2, 4 and 7), which can provide actuator access points (access openings) which can be operatively connected to the volume switches. The receptacles can provide sockets for receiving the electrical contacts (pins) of the switch actuators of the external control when the tray is in the closed position. The switch actuators can be aligned with actuator access points and volume switches so that when the tray is pushed inwardly in the closed position the switch actuators will pass through the access points and engage and contact the volume switches as the right or left portion of the rocker arm is pressed to increase or decrease the volume (sound) as desired by the user.
The external control may be used when the tray is in the closed position regardless of whether a data card is in the tray. In the open position of the tray, the external control can be substantially prevented from adjusting, controlling or regulating the electronic device.
The external control itself may include a ledge that defines a cavity, such that an object (such as a tool or fingernail) can be inserted into the cavity, engage the ledge, and pulled outwardly so as to slide the external control along with the tray out of the tray-receiving opening. The external control may also cooperate with a flexible member or spring loaded device, so that the external control may be removed by pressing on its surface, or by inserting a pointed tool into an exposed hole in the external control to actuate the flexible member or spring loaded device.
In an alternate embodiment of the invention, the external control described herein need not be used in conjunction with a holding tray. Referring to FIGS. 10 and 11, for example, the data card 138 does not sit in a tray, but rather is held within the electronic device by a push-push connector 182. To insert the data card 138 in to the push-push connector, the data card is pushed into a slot 184 until it engages with, and is secured by the push-push connector (for example, in a spring-loaded manner). The external control is then attached to the electronic device at the opening of the slot, thereby hiding the data card and the push-pull connector. When attached, a portion of the external control may extend into the slot.
To remove the data card, the external control is removed from the electronic device (e.g., by fingernail or with a tool), and the data card is pushed further into the slot 184 until the push-push connector releases the data card. In this embodiment, the external control 180 (which is depicted as a volume control) acts as a door or a cover that hides the push-push connector and the data card. Except for the absence of the tray, the external control 180 may be implemented in the same manner, with the same structure, and interact with internal switches in the same manner, as the external control described in conjunction with FIGS. 1-9.
The external control can also be implemented as: a switch actuator with a tactile contact, volume key, volume button, volume up button, volume down button, rocker arm, volume dial, volume knob, colored control, power button, camera button, video button, or as any other suitable control.
The electronic switch with which the external control interacts can comprise: a switch, tactile switch, surface mounted tactile (SMT) switch, modular switch, rocker switch, colored switch, or any other suitable component.
In those implementations using a holding tray, the holding tray can comprise a generally rectangular tray, a removable tray, a slidable tray, or any other suitable component. The tray can be molded of fabricated of plastic, aluminum or other light weight metal, a composite material, or any other suitable material. The tray-receiving opening may be implemented in a varietly of ways. For example, it can include elongated transverse grooves which can provide rails or tracks 172 (FIGS. 2 and 4) for slidably receiving the holding tray. The holding trays can have detents 174 (FIGS. 5 and 6) providing track-engageable locks for interlockingly engaging the tracks and securing the tray when the tray is in the closed position.
The electronic device can also include one or more electronic data card readers 150 for reading the data cards.
The memory module or SIM may have any suitable format and any suitable form factor. For example, the SIM may be a subscriber identity module card (SIM card), full-size SIM 1st form factor (1FF) card, mini-SIM 2nd form-factor (2FF) card, micro-SIM 3rd form-factor (3FF) card, nano-SIM 4th form-factor (4FF) card. The memory module may be, for example, a secure device card (SD card), standard SD card, miniSD card, microSD (uSD) card, memory card, storage card, expanded external memory card.
The electronic device can comprise a portable electronic device selected from the group consisting of: a radiotelephone, cellular (cell) phone, mobile phone, smart phone, qwerty phone, flip phone, slider phone, android phone, tablet phone, camera phone, clamshell device, portable networking device, portable gaming device, mobile communications device, personal digital assistant (PDA), wireless e-mail device, a two way pager, internet communication device, electronic reading device, incoming call notifier, answering machine, computer, or any other suitable device.
Although embodiments of the invention have been shown and described, it is to be understood that various modifications, substitutions, and rearrangements of parts, components, and/or process steps can be made by those skilled in the art without departing from the novel spirit and scope of this invention.
