RECEPTACLE AND ELECTRONIC DEVICE INCLUDING THE SAME

BACKGROUND
(1) Field

Various embodiments of the present invention relate to a receptacle which electrically connects an electronic device to a device external to the electronic device (e.g., an external device).

(2) Description of the Related Art

An electronic device such as laptop computers or tablet personal computers (PCs) can have at least one or more connector holes formed (or provided) in a side member of the electronic device to be connected to an external device external to the electronic device. A connection part (e.g., plug) of the external device is connected to a connection part (e.g., receptacle) arranged inside the electronic device, through a connector hole, to electrically connect the external device to the electronic device and to provide mutual signal transmission/reception and/or electrical charging of the electronic device and/or the external device.

SUMMARY

It may be difficult to reduce an overall thickness and slim down an electronic device having the receptacle for receiving the connection part of an external device. For example, in an electronic device, it can be difficult to slim down a housing of the electronic device due to the mounting (e.g., a mounting thickness) of a connection socket of the receptacle.

According to various embodiments of the present invention, a receptacle which reduces a thickness of a housing of an electronic device, and an electronic device including the same may be provided.

According to various embodiments of the present invention, a receptacle capable of ground (GND) and/or electromagnetic interference (EMI)/electrostatic discharge (ESD) shielding, and an electronic device including the same may be provided.

According to various embodiments of the present invention, an electronic device may include a housing which includes a front cover arranged to face a first direction, a rear cover arranged to face a second direction opposite to the first direction, a side member arranged to surround at least a part of the space between the front and rear covers and including a connector hole, and a receptacle at least a portion of which is rotatably assembled on the rear cover, and which is arranged at an entrance of the connector hole. The receptacle may include a first metal member including a plurality of connection pins, and including a protruding connection part connected to a plug, a door cover which is arranged to face the first metal member, and rotates towards the second direction around a hinge axis when the plug is connected to the protruding connection part, and rotates towards the first direction around the hinge axis when the connected plug becomes separated, and a second metal member which faces the first metal member, and is coupled to the door cover.

According to various embodiments of the present invention, it may be advantageous to slim down an electronic device such as a laptop computer, for example, a notebook computer or a tablet PC.

According to various embodiments of the present invention, a metal member having a plurality of connection pins is configured to contact with a rear metal member, whereby the grounding of a plug is possible and EMI shielding may be possible.

According to various embodiments of the present invention, since a rotatable door cover may have a structure separable from a housing, automatic optical inspection is easy, and manual soldering is easy.

According to various embodiments of the present invention, the grounding of the connected plug is possible and EMI shielding is possible, thereby improving Wi-Fi performance and enabling high-speed data transmission (e.g., transmission rate of 5 Gbps/10 Gbps/48 Gbps).

DETAILED DESCRIPTION

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Hereinafter, various embodiments of the present invention will be described with reference to the accompanying drawings. However, it should be understood that this does not intend to limit the present disclosure to specific embodiments, and includes various modifications, equivalents, and/or alternatives of the embodiments of the present disclosure. In connection with the description of the drawings, like reference numerals may be used for like components.

It will be understood that when an element is referred to as being related to another element such as being “on” another element, it can be directly on the other element or intervening elements may be present therebetween. In contrast, when an element is referred to as being related to another element such as being “directly on” another element, there are no intervening elements present.

It will be understood that, although the terms “first,” “second,” “third” etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, “a first element,” “component,” “region,” “layer” or “section” discussed below could be termed a second element, component, region, layer or section without departing from the teachings herein.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. Within the Figures and the text of the disclosure, a reference number indicating a singular form of an element may also be used to reference a plurality of the singular element. As used herein, “a”, “an,” “the,” and “at least one” do not denote a limitation of quantity, and are intended to include both the singular and plural, unless the context clearly indicates otherwise. For example, “an element” has the same meaning as “at least one element,” unless the context clearly indicates otherwise. “At least one” is not to be construed as limiting “a” or “an.” “Or” means “and/or.” As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items.

It will be further understood that the terms “comprises” and/or “comprising,” or “includes” and/or “including” when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, components, and/or groups thereof.

Furthermore, relative terms, such as “lower” or “bottom” and “upper” or “top,” may be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the “lower” side of other elements would then be oriented on “upper” sides of the other elements. The term “lower,” can therefore, encompasses both an orientation of “lower” and “upper,” depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as “below” or “beneath” other elements would then be oriented “above” the other elements. The terms “below” or “beneath” can, therefore, encompass both an orientation of above and below.

“About” or “approximately” as used herein is inclusive of the stated value and means within an acceptable range of deviation for the particular value as determined by one of ordinary skill in the art, considering the measurement in question and the error associated with measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “about” can mean within one or more standard deviations, or within ±30%, 20%, 10% or 5% of the stated value.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Embodiments are described herein with reference to cross section illustrations that are schematic illustrations of idealized embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments described herein should not be construed as limited to the particular shapes of regions as illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. For example, a region illustrated or described as flat may, typically, have rough and/or nonlinear features. Moreover, sharp angles that are illustrated may be rounded. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the precise shape of a region and are not intended to limit the scope of the present claims.

According to various embodiments, the rear cover 102 may have the hinge 120 to which a hinge arm 415 (shown in FIG. 6) of a door cover 41 is rotatable coupled, by insertion of the hinge 120 into the hinge arm 415.

FIG. 11A is a front cross-sectional view illustrating the receptacle 40 when the plug is not inserted (or not insertable) into the receptacle 40 according to various embodiments of the present invention. FIG. 11B is a cross-sectional side view illustrating the receptacle 40 when the plug is not inserted according to various embodiments of the present invention.

Referring to FIG. 11A and FIG. 11B, according to various embodiments, in a state in which the plug is not inserted into the receptacle 40, the door cover 41 may be in a state of being closest to the first metal member 42 along the Z direction (e.g., thickness direction). The door cover 41 which is closest to the first metal member 42 is closed. According to various embodiments, the door cover 41 may be in a state of being rotatable around the hinge axis (a) by approximately a first angle (θ), for example, about 5 degrees with respect to a horizontal axis (a1) (e.g., a reference axis or reference X-Y plane). The first angle (θ) does not need to be limited to 5 degrees, and may be about 10 degrees. The door cover 41 may receive a rotational force in a first direction (e.g., the first direction ({circle around (1)}) shown in FIG. 4) by an elastic body 1024, for example, a rubber. In an embodiment, the elastic body 1024 such as the rubber may provide a biasing force in the first direction to maintain the door cover 41 being closed (e.g., closest to the first metal member 42 along the thickness direction). That is, the receptacle 40 which is closed includes the door cover 41 closest to the first metal member 42.

According to various embodiments, in a state in which the door cover 41 is closed, at least a portion of the protruding connection part 421 may be covered by the door cover 41 to be invisible from outside of the receptacle 40. That is, receptacle 40 which closed by the door cover 41 includes the protruding connection part 421 covered and not exposed to outside the receptacle 40. For example, when the rotation angle (00) of the door cover 41 is about 10 degrees, an entirety of the protruding connection part 421 may be covered by the door cover 41. In an embodiment, when the rotation angle (θ) of the door cover 41 is about 10 degrees or less relative to the reference plane, an entirety of the protruding connection part 421 may be covered by the door cover 41 such that the protruding connection part 421 at an inner area of the receptacle 40 is minimally or non-exposed to outside the receptacle 40.

In an embodiment, referring to FIGS. 3B and 11B, within the receptacle 40, the door cover 41 faces the first metal member 42 along a thickness direction (e.g., Z direction) of the receptacle 40. Each of the door cover 41 and the first metal member 42 has a thickness along the thickness direction, and the receptacle 40 which is closed includes the thickness of the door cover 41 overlapping the thickness of the first metal member 42.

According to various embodiments, the third metal member 44 may always maintain (e.g., shown in FIG. 12B) a state of being connected to the first metal member 42 regardless of whether the door cover 41 rotates to be open or is minimally rotated to be closed.

FIG. 12A is a front cross-sectional view illustrating the receptacle 40 when the plug 50 is insertable into the receptacle 40 according to various embodiments of the present invention. FIG. 12B is a cross-sectional view illustrating the receptacle 40 when the plug 50 is inserted into the receptacle 40 according to various embodiments of the present invention. FIG. 12C and FIG. 12D are perspective views respectively illustrating the receptacle 40 having the plug 50 inserted according to various embodiments of the present invention.

Referring to FIG. 12A to FIG. 12D, according to various embodiments, when the door cover 41 is rotated about the hinge axis (a) toward a second direction (e.g., the second direction ({circle around (2)}) shown in FIG. 3B) in order for the plug 50 to be insertable into the receptacle 40, the plug 50 may be inserted into the receptacle 40. For example, where portions of the door cover 41 are above fixing dips 420 of the first metal member 42 in FIG. 11A (e.g., closed door cover), the same portions are below the fixing dips 420 in FIG. 12A (e.g., open door cover), along the Z direction.

According to various embodiments, when the plug 50 is inserted into the receptacle 40, a connection terminal of the plug 50 may be connected to the protruding connection part 421 and maintain a connected state with the first metal member 42. Here, the door cover 41 which is open may be parallel to a horizontal axis (e.g., the horizontal axis (a1) shown in FIG. 11B), and may be parallel to a bottom surface of a rear cover 102.

According to various embodiments, the door cover 41 may be prevented from further rotating in the second direction ({circle around (2)}) by engagement of the front and rear over-rotation prevention hooking protrusions 411-1, 411-2, 412-1 and 412-2 of the door cover 41 with may a portion (not shown) of the rear cover 102 as described above.

Taking FIG. 11B together with FIG. 12B, for example, the second metal member 43 is between the first metal member 42 and the door cover 41, coupled to the door cover 41 and moveable together with the door cover 41. The receptacle 40 which is open (FIG. 12B) includes the door cover 41 and the second metal member 43 together moved away from the first metal member 42, together with the protruding electrical connection part 421 connectable to the external device plug 50.

FIG. 13 is a perspective view illustrating a state in which an elastic body 1024 is arranged on a rear cover 102 according to various embodiments of the present invention.

Referring to FIG. 13, according to various embodiments, when an inserted plug (e.g., the plug 50 shown in FIG. 12C) is separated from a receptacle 40 (shown in FIG. 11A), a door cover 41 (shown in FIG. 11B) may rotate by a first angle (θ) (shown in FIG. 11B) by a biasing force provided by the elastic body 1024, and return to an original position. The original position of the door cover 41 may be a closed position (refer to FIGS. 11A and 11B).

According to various embodiments, the elastic body 1024 may be attached to the rear cover 102, be arranged near the hinge 120, and be arranged closer to the opening 1020 than the hinge 120 along the Y direction. According to various embodiments, when the rear cover 102 is viewed from the above (e.g., plan view or view of X-Y plane), the elastic body 1024 may be positioned between the hinge 120 and the opening 1020. Taking FIGS. 4 and 13 together, the elastic body 1024 is between the door cover 41 and the rear cover 102 along the thickness direction. For example, a portion of the door cover 41 which corresponds to the bottom portion 442 of the third metal member 44 may overlap the elastic body 1024, without being limited thereto.

According to various embodiments, the elastic body 1024 may be arranged between the rear cover 102 and a door cover 41 shown in FIG. 11B. For example, the elastic body 1024 which is compressible, may be compressed according to rotation of the door cover 41 shown in FIG. 11B, or a compressed state may be released when the door cover 41 is opened.

According to various embodiments, when the plug 50 (shown in FIG. 12C) is inserted into the receptacle 40, the elastic body 1024 may be in a state of being compressed by the door cover 41 which is open. Conversely, when the plug is separated from the receptacle 40 and the door cover 41 is closed, the elastic body 1024 may provide a rotational force to the door cover 41 while the compressed state is released and the elastic body 1024 returns to an uncompressed shape or thickness. For example, the elastic body 1024 may be a discrete shape or pattern, and may be a rubber material having elasticity.
