Patent Description:
Recently, with the widespread use of electronic devices having independent operating systems, the electronic devices have evolved into mediums having various functions integrated. Accordingly, electronic parts for supporting functional operations of the electronic devices have been gradually diversified, and to receive a plurality of electronic parts, the electronic devices have solved inner spatial limitations based on an improvement in software or hardware.

<CIT> discloses that a printed circuit board connector and an electronic device including thereof are provided to arrange the connector plug by passing the sub printed circuit board(PCB). A printed circuit board connector comprises connector sockets(<NUM>,<NUM>), a main PCB(<NUM>), a connector plug(<NUM>), a sub PCB(<NUM>), and a through hole(<NUM>). The connector sockets are fixed to the main printed circuit. The connector plug(<NUM>) is fixed to the sub PCB. The sub PCB is laminated on upper side of the main printed circuit board. The connector plug passes through the through hole(<NUM>) of the sub PCB. The connector plug is inserted into the connector socket.

<CIT> discloses that a mobile terminal using a multi-function socket and its method are provided to reduce the size of a mobile terminal by performing a data input/output function and a charging function by using a single socket unit. A connector(<NUM>) is connected with an external device and sets an electrical connection. A controller(<NUM>) receives or transmits at least one signal through at least one predetermined path according to at least one identification signal by interworking with the connector(<NUM>) and a switching unit(<NUM>), and generates a control signal for controlling at least one signal. At least one signal is one of a power signal and data.

<CIT> discloses that a connector and an electronic device having the connector are disclosed. The connector includes: a housing formed with an insulator and mounted at a substrate in order to process a digital signal; a pair of sockets that process a Radio Frequency (RF) signal; a pair of terminals formed at a sub PCB in order to process the RF signal; and a signal processor that processes the RF signal and the digital signal. Various embodiments of the present disclosure are possible.

<CIT> discloses that an electronic apparatus includes a frame, a plurality of flexible circuit boards, and a plurality of hardware devices. The frame includes a first frame body and a second frame body. The first frame body and the second frame body are spaced apart from each other, and define an accommodation space therebetween. The flexible circuit boards are accommodated in the accommodation space. Each flexible circuit board includes a first edge and a second edge opposite to the first edge. The first edge is connected to the first frame body. The second edge is connected to the second frame body. The hardware devices are disposed on the corresponding flexible circuit boards.

Electronic parts received in an electronic device may transmit or receive signals related to performing functions of the corresponding electronic parts, by being electrically connected with a printed circuit board by connectors. Because the plurality of connectors for supporting connection with the electronic parts are mounted on the printed circuit board, a space for mounting another connector or electronic part may be narrow, which may act as an impediment to a structural improvement of the electronic device.

Various embodiments of the disclosure described herein provide a connector having a stack structure for ensuring an available space (e.g., a space in the X-axis or Y-axis direction) on a printed circuit board by implementing at least some of a plurality of connectors mounted on the printed circuit board in a vertical stack (e.g., Z-axis stack) structure, and an electronic device including the same.

For example, the printed circuit board <NUM> may be connected with the components of the electronic device <NUM>, based on at least one signal line formed on at least a partial area of the printed circuit board <NUM>. In this regard, at least one module for supporting electrical connection between a component of the electronic device <NUM> that is spaced apart from the printed circuit board <NUM> (or, not mounted on the printed circuit board <NUM>) and the signal line may be mounted on at least a partial area of the printed circuit board <NUM>. According to an embodiment, the module may include a socket and/or a header on at least a partial area, and the aforementioned connector may be understood as a name including the module and the socket. In an embodiment, the module and another module may be vertically stacked on each other based on the socket and/or the header, and the stack structure of the plurality of modules may support multiple connections between the printed circuit board <NUM> and the components of the electronic device <NUM>. Hereinafter, structural or functional characteristics of a structure in which a plurality of modules are stacked will be described.

<FIG> is a view illustrating at least a partial area of the printed circuit board according to an embodiment, and <FIG> is a view illustrating a first module and a second module according to an embodiment.

Referring to <FIG> and <FIG>, the printed circuit board <NUM> may be formed in a specified size or shape depending on structural or inner spatial design of the electronic device (<NUM> of <FIG>), and components (or electronic parts) received in the electronic device <NUM> may be disposed in an area that overlaps at least part of the printed circuit board <NUM>, or may be disposed in an area that avoids the printed circuit board <NUM> (or, an area spaced apart from the printed circuit board <NUM>). Accordingly, the components of the electronic device <NUM> may be directly connected with the printed circuit board <NUM>, or may be connected with the printed circuit board <NUM> through a specified member. For example, at least some components <NUM> and/or <NUM> of the electronic device <NUM> (e.g., components disposed in an area that overlaps at least part of the printed circuit board <NUM>) may be connected with the printed circuit board <NUM> by being mounted on one area of the printed circuit board <NUM>. Alternatively, at least some other components of the electronic device <NUM> (e.g., components disposed in an area that avoids the printed circuit board <NUM> or is spaced apart from the printed circuit board <NUM>) may be electrically connected with the printed circuit board <NUM> by being mounted on or connected to one area of at least one module mounted on the printed circuit board <NUM>.

In an embodiment, to overcome a limitation of space on the printed circuit board <NUM>, at least a part of the at least one module may be implemented with the aforementioned stack structure of the plurality of modules. For example, a plurality of modules may be mounted on at least a partial area of the printed circuit board <NUM> in the form of a stack structure in which the plurality of modules are vertically stacked (e.g., stacked in the Z-axis direction) with respect to the printed circuit board <NUM>.

According to an embodiment, the structure in which the plurality of modules are stacked may include the first module <NUM> including a first socket for connection with a first header <NUM> mounted on the printed circuit board <NUM> and the second module <NUM> including a second socket for connection with a second header included in the first module <NUM>. In other words, the stack structure of the plurality of modules may include the first module <NUM> mounted on the printed circuit board <NUM> as a first layer and electrically connected with the printed circuit board <NUM> and the second module <NUM> stacked on the top of the first module <NUM> as a second layer and electrically connected with the first module <NUM>. In various embodiments, the stack structure of the plurality of modules that is received in the electronic device <NUM> in the form of being mounted on the printed circuit board <NUM> may further include at least one module stacked on the top of the second module <NUM>, in addition to the first module <NUM> and the second module <NUM> as long as the stack structure has a height in a range allowed in the electronic device <NUM> based on the thickness of the electronic device <NUM>.

According to the above-described stack structure of the plurality of modules, a space (e.g., a space in the X-axis direction or the Y-axis direction) on the printed circuit board <NUM> may be implemented as a blank. For example, a mounting space (<NUM> of <FIG>) that one module (e.g., the second connector (<NUM> of <FIG>)) among the plurality of modules (e.g., the first module <NUM> and the second module <NUM>) constituting the stack structure occupies when directly mounted on the printed circuit board <NUM> may be implemented as a blank. Accordingly, the stack structure of the plurality of modules may enable the space <NUM> implemented as the blank to be used as a mounting space of another component (or electronic part) of the electronic device <NUM>, thereby achieving easy space design in the electronic device <NUM>.

<FIG> is a view illustrating a stack form of the first module and the second module according to the invention.

Referring to <FIG>, the first module <NUM> and the second module <NUM> included in the above-described stack structure of the plurality of modules may differ from each other in terms of the shape of at least part, or may include different components, depending on a stack sequence. For example, the first module <NUM> mounted on the printed circuit board <NUM> as the first layer may include a shape or a component that is able to be engaged with the printed circuit board <NUM>. Correspondingly the second module <NUM> stacked on the top of the first module <NUM> as the second layer may include a shape or a component that is able to be engaged with the first module <NUM>.

In regard to the above description, the printed circuit board <NUM> includes the first header <NUM> that supports engagement and electrical connection with the first module <NUM> mounted on the printed circuit board <NUM> as the first layer. The first header <NUM> is electrically connected with at least a part of at least one signal line included in the printed circuit board <NUM>.

The first module <NUM> includes, on one surface thereof (e.g., a surface facing the printed circuit board <NUM>), a first socket <NUM> for engagement and electrical connection with the first header <NUM> on the printed circuit board <NUM> includes, on an opposite surface thereof, a second header <NUM> for supporting engagement and electrical connection with the second module <NUM>. The first socket <NUM> may be implemented in a shape corresponding to the first header <NUM> of the printed circuit board <NUM>, for example, in a shape that is at least partially fit into the first header <NUM> or receives at least part of the first header <NUM>. In an embodiment, engagement between the first socket <NUM> of the first module <NUM> and the first header <NUM> of the printed circuit board <NUM> may mean that an electrical path extending from the printed circuit board <NUM> to the first module <NUM> is formed. In various embodiments, a stiffener <NUM> may be disposed in an area around the engagement of the first socket <NUM> and the first header <NUM>. The stiffener <NUM> may support firm engagement between the first socket <NUM> and the first header <NUM>, or may support a load depending on the first module <NUM> and/or the second module <NUM>. The second header <NUM> may be implemented in a shape that is the same as, or similar to, the shape of the first header <NUM> of the printed circuit board <NUM>.

The second module <NUM> includes, on one surface thereof (e.g., a surface facing the first module <NUM>), a second socket <NUM> for engagement with the second header <NUM> of the first module <NUM>. For example, the second socket <NUM> may be implemented in a shape that is the same as, or similar to, the shape of the first socket <NUM> of the first module <NUM>, and when the second socket <NUM> is engaged with the second header <NUM> of the first module <NUM>, an electrical path extending from the printed circuit board <NUM> to the second module <NUM> via the first module <NUM> may be formed.

The first header <NUM> includes a plurality of first conductive terminals. At least some of the plurality of first conductive terminals may pass through at least part of the first module <NUM> and may extend to the second header <NUM>. Accordingly, an electrical path extending from the printed circuit board <NUM> to the second module <NUM> via the first module <NUM> may be formed.

According to various embodiments, the headers (e.g., the first header <NUM> and the second header <NUM>) and the sockets (e.g., the first socket <NUM> and the second socket <NUM>) described above may be implemented in various shapes other than the illustrated shapes as long as the headers and the sockets support engagement and electrical connection between the printed circuit board <NUM> and the first module <NUM> or between the first module <NUM> and the second module <NUM>. Furthermore, when the stack structure of the plurality of modules further includes at least one module in addition to the first module <NUM> and the second module <NUM> as described above, the headers and the sockets may be alternately disposed on the plurality of modules included in the stack structure of the plurality of modules.

In an embodiment, the first module <NUM> may include a first flexible printed circuit board <NUM> for supporting electrical connection of the first socket <NUM> and a first electronic part <NUM> (e.g., an electronic part disposed in an area that avoids the printed circuit board <NUM> or is spaced apart from the printed circuit board <NUM>). The first flexible printed circuit board <NUM> may include at least one signal line for transferring a signal or data. For example, one area may be received in the first module <NUM> and may be electrically connected with the first socket <NUM>, and an opposite area may be exposed outside the first module <NUM> and may be electrically connected with the first electronic part <NUM> mounted on the exposed area. According to the above description, a signal or data provided through the printed circuit board <NUM> of the electronic device <NUM> may be transferred to the first electronic part <NUM> via the first header <NUM> on the printed circuit board <NUM>, the first socket <NUM> of the first module <NUM> that is engaged with the first header <NUM>, and the first flexible printed circuit board <NUM> connected with the first socket <NUM>.

Correspondingly, the second module <NUM> may include a second flexible printed circuit board <NUM> for supporting electrical connection of the second socket <NUM> and a second electronic part <NUM>. Similarly to the first flexible printed circuit board <NUM>, the second flexible printed circuit board <NUM> may include at least one signal line and may be electrically connected with the second socket <NUM> and the second electronic part <NUM>. The second electronic part <NUM> may receive a signal or data from the printed circuit board <NUM>, based on an electrical path constituted by the first header <NUM> on the printed circuit board <NUM>, the first socket <NUM> of the first module <NUM> that is engaged with the first header <NUM>, the second header <NUM> of the first module <NUM>, the second socket <NUM> of the second module <NUM> that is engaged with the second header <NUM>, and the second flexible printed circuit board <NUM> connected with the second socket <NUM>.

According to an embodiment, the above-described electrical connection between the printed circuit board <NUM>, the first module <NUM>, and the second module <NUM> may be implemented with at least one terminal (e.g., a pin) that the headers (e.g., the first header <NUM> and the second header <NUM>) and the sockets (e.g., the first socket <NUM> and the second socket <NUM>) include. The at least one terminal may enable conduction of electricity between the engaged components to allow a signal or data transmitted from the processor mounted on the printed circuit board <NUM> to be transferred to the first electronic part <NUM> included in the first module <NUM> or the second electronic part <NUM> included in the second module <NUM>.

The first header <NUM> on the printed circuit board <NUM> includes a first terminal subset including at least one terminal (e.g., first to tenth pins) and a second terminal subset including at least one other terminal (e.g., eleventh to twentieth pins). The first socket <NUM> engaged with the first header <NUM> includes a third terminal subset constituted by at least one terminal (e.g., first to tenth pins) for physical or electrical connection with the first terminal subset and a fourth terminal subset constituted by at least one terminal (e.g., eleventh to twentieth pins) for physical or electrical connection with the second terminal subset. According to an embodiment, when the first header <NUM> and the first socket <NUM> are engaged with each other, the first terminal subset and the third terminal subset may be connected, and therefore electrical connection between the printed circuit board <NUM> and the first electronic part <NUM> (or, between the printed circuit board <NUM> and the first flexible printed circuit board <NUM> included in the first module <NUM>) may be implemented.

Similarly to the above description, the second header <NUM> of the first module <NUM> includes at least one terminal (e.g., first to tenth pins), and the second socket <NUM> of the second module <NUM> includes at least one terminal (e.g., first to tenth pins) for physical or electrical connection with the at least one terminal of the second header <NUM>. In this regard, when the first header <NUM> and the first socket <NUM> are engaged together and the second header <NUM> and the second socket <NUM> are engaged together, the second terminal subset of the first header <NUM> and the fourth terminal subset of the first socket <NUM> may be connected together, and the at least one terminal included in the second header <NUM> and the at least one terminal included in the second socket <NUM> may be connected together. Accordingly, electrical connection between the printed circuit board <NUM> and the second electronic part <NUM> (or, between the printed circuit board <NUM> and the second flexible printed circuit board <NUM> included in the second module <NUM>) may be implemented.

In various embodiments, when a third module is stacked on the top of the second module <NUM>, the at least one terminal (e.g., the first to tenth pins) included in the second header <NUM> and the at least one terminal (e.g., the first to tenth pins) included in the second socket <NUM> may each be implemented in a terminal subset form. Furthermore, to support electrical connection between the printed circuit board <NUM> and a third electronic part included in the third module, the second header <NUM> and the second socket <NUM> may each further include a terminal subset constituted by at least one terminal (e.g., eleventh to twentieth pins).

The first terminal subset included in the first header <NUM> on the printed circuit board <NUM> and the third terminal subset included in the first socket <NUM> of the first module <NUM> are connected, and therefore a signal or data transmitted from the processor mounted on the printed circuit board <NUM> is transferred to the first electronic part through the printed circuit board <NUM> and the first module <NUM>. Correspondingly, the second terminal subset included in the first header <NUM> on the printed circuit board <NUM> and the fourth terminal subset included in the first socket <NUM> of the first module <NUM> are connected, and the at least one terminal included in the second header <NUM> of the first module <NUM> and the at least one terminal included in the second socket <NUM> of the second module <NUM> are connected. Accordingly, a signal or data transmitted from the processor on the printed circuit board <NUM> is transferred to the second electronic part <NUM> through the printed circuit board <NUM>, the first module <NUM>, and the second module <NUM>.

<FIG> is a view illustrating an application example of a stack structure of a plurality of modules according to an embodiment.

As described above, the stack structure of the plurality of modules according to the embodiment may support electrical connection between a printed circuit board and an electronic part disposed in an area that avoids the printed circuit board or is spaced apart from the printed circuit board.

For example, referring to <FIG>, the stack structure <NUM> of the plurality of modules may support multiple connections between a first electronic part (e.g., the first camera module <NUM>) and a second electronic part (e.g., the battery <NUM>) of the electronic device <NUM> and the printed circuit board <NUM>, based on the plurality of modules (e.g., the first module <NUM> and the second module <NUM> of <FIG>). According to various embodiments, in multiple connections between the printed circuit board <NUM> and electronic parts that the stack structure <NUM> of the plurality of modules supports, a combination of the electronic parts is not limited to that described above (e.g., the first camera module <NUM> and the battery <NUM>). For example, a combination of the electronic parts may include various combinations in which mutual electrical noise is slight (e.g., the receiver module (<NUM> of <FIG>) and the battery <NUM>, the sensor module (<NUM> of <FIG>) and the battery <NUM>, or the LED module (<NUM> of <FIG>) and the battery <NUM>). Accordingly, the stack structure <NUM> of the plurality of modules may be disposed on various areas of the printed circuit board <NUM>.

<FIG> is a view illustrating a process of transferring a signal to an electronic part according to an embodiment.

Referring to <FIG>, in operation <NUM>, an event related to operation of a function (e.g., sound output, sensing, or photographing) embedded in the electronic device <NUM> may be generated on the electronic device (<NUM> of <FIG>).
