Description

head-mounted display device

[0001] One embodiment disclosed in this document relates to a head mounted display device (HMD), and more particularly, to a power connection structure of the head mounted display device.

[0002] Wearable electronic devices that can be worn directly on the body are becoming increasingly popular. Wearable electronic devices can be mounted on parts of the body, such as the wrist, ankle, neck, waist, or head, thereby enhancing mobility and portability. As an example of such wearable electronic devices, a head-mounted display device (HMD), which is mounted on the user's head and displays images, may be equipped with a wearable part so that it can be mounted on the head. Such HMD devices may include augmented reality (AR) devices that implement AR, and virtual reality (VR) devices that implement VR.

[0003] The HMD device can be powered by a built-in battery or by an external power source via a cable connected to the HMD device. If the HMD device is powered externally via a cable, the HMD device may include a connector pad (or interface) that connects to the cable to receive power.

[0004] When a connector pad and a cable are combined to supply power to an HMD device, one or more terminals arranged on the connector pad and one or more pins arranged on the cable may come into contact and be electrically and / or physically connected. During the process of making contact between the terminal and the pin, the terminal and the pin may come into unstable contact or a poor contact may occur, resulting in an arc, which may cause damage to the connector pad or pin.

[0005] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0006] A head mounted display device according to one embodiment of the present disclosure can provide a stable connection with a cable supplying external power.

[0007] A head mounted display device according to one embodiment of the present disclosure may include a main frame, a power cable for supplying external power to electrical components arranged inside the main frame, and a cable receiving portion located on one side of the main frame and formed so that the power cable is detachably connected. The power cable may include a connector pin having a head portion arranged so that one side thereof, which is connected to the cable receiving portion, is exposed. The cable receiving portion may include a plurality of connector pads positioned to correspond to the connector pins when the power cable is connected. When the power cable moves from an upper side to a lower side of the cable receiving portion and is connected, a second pad included in the plurality of connector pads and a second pin included in the connector pin are respectively connected, and after a predetermined delay has elapsed, a first pad included in the plurality of connector pads and a first pin included in the connector pin are connected.

[0008] A power supply device according to one embodiment of the present disclosure may be configured to supply power to a wearable device. The power supply device may include a cable including a power supply line and a communication line, a first assembly connected to the cable, and a second assembly physically coupled or separated from the first assembly. One of the first assembly and the second assembly may include a first pad and a second pad, and the other of the first assembly and the second assembly may include a first pin that contacts the first pad and a second pin that contacts the second pad when the first assembly and the second assembly are coupled. When at least one of the first assembly and the second assembly moves in a first direction and is coupled to each other, contact between the first pad and the first pin may be made relatively later than contact between the second pad and the second pin. The first pin and the second pin may each include a head portion protruding in a second direction that is perpendicular to the first direction and in which the first assembly and the second assembly face each other, and a pin body that provides elasticity so that the head portion moves in the second direction when the first pin and the second pin are coupled with the first pad and the second pad, respectively.

[0009] However, the problem to be solved in this disclosure is not limited to the problem mentioned above, and may be determined in various ways without departing from the spirit and scope of this disclosure.

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0042] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

[0055] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0056] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0057] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0058] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0059] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0060] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0061] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0062] Each of the external electronic devices (102, 104) may be the same type of device as or a different type of device than the electronic device (101). According to one embodiment, all or part of the operations executed by the electronic device (101) may be executed by one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) needs to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of executing the function or service itself or in addition, request one or more external electronic devices to execute at least a part of the function or service. The one or more external electronic devices that receive the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a part of a response to the request. For example, an external electronic device (102) renders content data executed in an application and transmits it to an electronic device (101), and the electronic device (101) that receives the data can output the content data to a display module. If the electronic device (101) detects user movement through an IMU sensor, the processor of the electronic device (101) can correct the rendering data received from the external electronic device (102) based on the movement information and output it to the display module. Alternatively, the motion information can be transmitted to the external electronic device (102) to request rendering so that the screen data is updated accordingly. According to various embodiments, the external electronic device (102) may be various types of devices, such as a smartphone or a case device that can store and charge the electronic device (101).

[0063] In the following description, the shape, structure, and operation of a head mounted display device (hereinafter referred to as an HMD device) that is mounted on a user's head and displays images (e.g., the HMD device (200) of FIG. 2) will be described.

[0142] According to one embodiment, when the power cable (400) is fastened to the cable receiving portion (300), the rocker member (455) can be pushed by the cable receiving portion (300) to be drawn into the inside of the power cable (400), and thus, the power cable (400) can be slid downwardly of the cable receiving portion (300) by the user and fastened to the cable receiving portion (300).

[0143] According to one embodiment, in response to the button member (451) being pressed, the rocker member (455) can be pulled into the inside of the power cable (400). Accordingly, when the power cable (400) is detached from the cable receiving portion (300), the button member (451) is pressed by the user, and while the rocker member (455) is pulled into the inside of the power cable (400), the power cable (400) can be slid upward by the user and detached from the cable receiving portion (300).

[0144] According to one embodiment, a connector pin assembly (410) may include a connector pin casing (411) and a connector pin (420) arranged to be fixed to the connector pin casing (411). The connector pin (420) may include a first pin (420a), a second pin (420b), and a third pin (420c).

[0145] According to one embodiment, the connector pin assembly (410) may be arranged to be in contact with one surface of a printed circuit board (431). The first to third pins (420a, 420b, 420c) included in the connector pin assembly (410) may be electrically connected to the printed circuit board (431).

[0146] According to one embodiment, some of the first to third pins (420a, 420b, 420c) are arranged to be exposed to the outside of the connector pin casing (411), and the remaining parts are arranged inside the connector pin casing (411) and can be electrically connected to the printed circuit board (431). For example, the portions of the first to third pins (420a, 420b, 420c) that are exposed to the outside of the connector pin casing (411) can be formed in a semi-sphere shape.

[0147] According to one embodiment, the printed circuit board (431) may be connected to a cable member (433) to receive an electrical signal from the outside and transmit the received electrical signal to the first to third pins (420a, 420b, 420c). The printed circuit board (431) may provide an area for mounting a power supply circuit.

[0148] According to one embodiment, the cable member (433) may be detachably connected to the printed circuit board (431) by USB. For example, a USB terminal may be arranged on one side of the cable member (433) to which the cable member (433) and the printed circuit board (431) are connected, and a USB port (or USB connector) may be arranged on one side of the printed circuit board (431) to which the cable member (433) and the printed circuit board (431) are connected. For example, a USB port (or USB connector) may be arranged on one side of the cable member (433) to which the cable member (433) and the printed circuit board (431) are connected, and a USB terminal may be arranged on one side of the printed circuit board (431) to which the cable member (433) and the printed circuit board (431) are connected.

[0149] According to one embodiment, when the power cable (400) is fastened to the mounting space (300), an electric signal transmitted from the cable member (433) can be transmitted to the first to third pins (420a, 420b, 420c) via the printed circuit board (431). As the power cable (400) is fastened to the mounting space (300), the first to third pins (420a, 420b, 420c) are in electrical contact with the first to third connector pads (e.g., the first to third pads (320a, 320b, 320c) of FIG. 4), and an electric signal received from the outside can be input to the main frame (e.g., the main frame (210) of FIG. 2) to supply power.

[0150] FIG. 7 is a perspective view of a connector pin assembly (e.g., connector pin assembly (410) of FIG. 5) according to one embodiment of the present disclosure.

[0151] The embodiment of FIG. 7 can be optionally combined with the embodiments of FIGS. 2 to 6.

[0152] Referring to FIG. 7, a connector pin assembly (410) may include a connector pin casing (411) (e.g., the connector pin casing (411) of FIG. 6) and a connector pin (420) (e.g., the connector pin (420) of FIG. 5). The connector pin (420) may include a first pin (420a) (e.g., the first pin (420a) of FIG. 5), a second pin (420b) (e.g., the second pin (420b) of FIG. 5), and a third pin (420c) (e.g., the third pin (420c) of FIG. 5).

[0153] According to one embodiment, the first to third connector pins (420a, 420b, 420c) may be arranged to be fixed within a space formed by a connector pin casing (411) and a connector pin housing (e.g., connector pin housing (412, 413) of FIG. 8). The first to third connector pins (420a, 420b, 420c) may be formed to have an overall shape as follows. For example, at least one of the first to third connector pins (420a, 420b, 420c) may include a connector pin head (e.g., connector pin head (421) of FIG. 8) arranged so that a portion thereof is exposed to the upper side of the connector pin casing (411), a connector pin body (e.g., connector pin body (4221, 4222) of FIG. 7) arranged inside a space formed by the connector pin casing (411) and the connector pin housing (412, 413), and a connector pin tail (e.g., connector pin tail (423) of FIG. 8) arranged so that a portion thereof is exposed to the lower side of the connector pin casing (411).

[0154] According to one embodiment, the connector pin head (421) may have a semi-spherical shape. Since the connector pin head (421) has a semi-spherical shape, when a power cable (e.g., the power cable (400) of FIG. 2) is connected to a cable receiving portion (e.g., the cable receiving portion (300) of FIG. 4), the connector pad (320) and the connector pin (420) can be stably contacted. For example, since the connector pin (420) is formed in a semi-spherical shape, when it slides against the connector pad (320) and makes contact, the contact area between the connector pin (420) and the connector pad (320) can be maintained constant and the sliding can occur. However, the connector pin head (421) is not limited to that illustrated, and may be formed in various shapes, including a semi-spherical shape. For example, the connector pin head (421) may have a shape in which one end exposed to the outside of the connector pin casing (411) protrudes. For example, the connector pin head (421) may be formed in a shape in which a portion of the outer side is cut off (or removed) based on a hemispherical shape.

[0155] FIG. 8A is a cross-sectional view of a connector pin assembly (410) according to one embodiment of the present disclosure. FIG. 8A may be understood as a cross-sectional view illustrating a state in which a connector pin (420) is not in contact with a connector pad (320).

[0156] FIG. 8b is a cross-sectional view of a connector pin assembly (410) according to one embodiment of the present disclosure. FIG. 8b may be understood as a cross-sectional view showing an initial state in which a connector pin (420) is pressed by a connector pad (320).

[0157] Fig. 9 is a cross-sectional view of a connector pin assembly (410) according to one embodiment of the present disclosure. Fig. 9 may be understood as a cross-sectional view showing a state in which a connector pin (420) is fully pressed against a connector pad (320).

[0158] FIGS. 8A, 8B, and 9 may be understood as cross-sectional views taken along the line AA' of FIG. 7 to illustrate a series of operations in which a connector pin (420) (e.g., the third pin (420c) of FIG. 5) in FIG. 7 comes into contact with a connector pad (e.g., the third pad (320c) of FIG. 5). Accordingly, the connector pin (420) illustrated in FIGS. 8 and 9 will be described with a focus on the third pin (420c), but the description of the third pin (420c) may also be applied to the first pin (420a) and the second pin (420b).

[0159] The embodiments of FIGS. 8a, 8b and 9 can optionally be combined with the embodiment of FIG. 7.

[0160] Referring to FIGS. 8a, 8b, and 9, the connector pin assembly (410) may include a connector pin casing (411), a connector pin housing (412, 413), and a connector pin (420) (e.g., the first pin (420a), the second pin (420b), and the third connector pin (430c) of FIG. 7).

[0161] According to one embodiment, the connector pin casing (411) may form the exterior of the connector pin assembly (410). The connector pin housing (412, 413) may be positioned within the space formed by the connector pin casing (411). For example, the connector pin housing (412, 413) may be formed integrally with the connector pin casing (411) or may be formed as a separate configuration.

[0162] According to one embodiment, the connector pin (420) may include a connector pin head (421), a connector pin body (4221, 4222), and a connector pin tail (423). One end of the connector pin body (4221, 4222) may be connected to the connector pin head (421), and the other end of the connector pin body (4221, 4222) may be connected to the connector pin tail (423). For example, one end of a first connector pin body (4221) to be described later may be connected to the connector pin head (421), and the other end of the first connector pin body (4221) may be connected to one end of a second connector pin body (4222) to be described later. For example, the other end of the second connector pin body (4222) may be connected to the connector pin tail (423). The connector pin (420) may be made of a conductive material.

[0163] According to one embodiment, at least a portion of the connector pin (420) may be positioned within a space formed by the connector pin casing (411) and the connector pin housing (412, 413). For example, the body (4221, 4222) of the connector pin (420) may be positioned within the space.

[0164] According to one embodiment, the connector pin head (421) may be formed in a hemispherical shape. For example, the connector pin head (421) may be positioned so that a portion thereof is exposed to the upper side of the connector pin casing (411). For example, the connector pin head (421) may be positioned so as to be exposed in a negative second direction (e.g., -d2 direction). By forming the connector pin head (421) in a hemispherical shape, when the connector pad (320) is brought into contact with the connector pin head (421), the area of ​​the connector pad (320) in contact with the connector pin head (421) may be maintained constant.

[0165] According to one embodiment, the connector pin body (4221, 4222) may include a first connector pin body (4221) and a second connector pin body (4222). One side of the first connector pin body (4221) may be connected to the connector pin head (421). For example, the first connector pin body (4221) may be arranged in a horizontal direction. For example, the first connector pin body (4221) may be arranged substantially parallel to the first direction (e.g., +d1 direction or -d1 direction). The other side of the first connector pin body (4221) may be connected to one side of the second connector pin body (4222). The second connector pin body (4221) may be arranged in a vertical direction. The other side of the connector pin body (4222) may be connected to the connector pin tail (423).

[0166] According to one embodiment, the connector pin body (4221, 4222) can provide elastic force for the connector pin head (421) to protrude in the second direction. For example, the connector pin body (4221, 4222) may have a shape that bends at one point, but is not limited thereto, and the connector pin body (4221, 4222) may have various shapes and structures from the viewpoint of providing elastic force for the connector pin head (421) to protrude in the second direction when not pressed.

[0167] According to one embodiment, the connector pin tail (423) may be connected to the second connector pin body (4222). For example, the connector pin tail (423) may be arranged in a horizontal direction. The connector pin tail (423) may be arranged so that a portion thereof is exposed to the lower side of the connector pin casing (411). One side of the connector pin tail (423) may be connected to the second connector pin body (4222), and the other side of the connector pin tail (423) may be connected to a printed circuit board (e.g., the printed circuit board (431) of FIG. 6). When the power cable (400) is connected to an external power source, an electric signal may be input to the printed circuit board (431) and the connector pin (420) in that order through the cable member (e.g., the cable member (433) of FIG. 6).

[0168] According to one embodiment, when the power cable (400) is connected to the cable receiving portion (300), the connector pin (420) can come into contact with the connector pad (320). As the power cable (400) slides from the upper side to the lower side of the cable receiving portion (300), the connector pad (320) and the connector pin (420) can come into contact.

[0169] According to one embodiment, while the connector pin (420) slides toward the connector pad (320), the connector pin head (421) can come into contact with the connector pad (320). Due to the shapes of the first to third pads (320a, 320b, 320c) included in the connector pad (320), the first to third pads (320a, 320b, 320c) and their corresponding connector pin heads (421) can sequentially come into contact with each other. For example, while the connector pin (420) is sliding toward the connector pad (320), after the connector pin heads (421) of the second and third pads (320b, 320c) and the second and third pins (420b, 420c) are brought into contact with each other, a predetermined delay may elapse and the connector pin heads (421) of the first pad (320a) and the first pin (420a) may come into contact. As the connector pin heads (421) are formed in a hemispherical shape, the connector pin heads (421) can come into contact with the connector pads (320) by a certain area. For example, in FIG. 8, the connector pad (320) can be physically and / or electrically connected by making contact with the first contact area (C1) of the connector pin head (421), and in FIG. 9, the connector pad (320) can be physically and / or electrically connected by making contact with the second contact area (C2) of the connector pin head (421).

[0170] According to one embodiment, when the connector pin head (421) is pressed by the connector pad (320), the connector pin head (421) and the first connector pin body (4221) can be drawn inward a predetermined distance in the pressing direction. For example, the connector pin head (421), the connector pin body (4221, 4222), and the connector pin tail (423) constituting the connector pin (420) are made of an elastic conductive material, so that when there is no pressing by the connector pad (320), the connector pin (420) can return to the state of FIG. 8a through the state of FIG. 8b.

[0171] According to one embodiment, as the connector pin head (421) is formed in a hemispherical shape, the power cable (400) can provide a path for stably transmitting an electric signal transmitted to the cable receiving portion (300).

[0172] According to one embodiment, when a connector pin (420) comes into contact with a connector pad (320), a delay may occur between the time when a specific connector pin (e.g., a first pin (420a)) and a specific connector pad (e.g., a first pad (320a)) come into contact with another connector pin (e.g., a second and third pin (420b, 420c) and another connector pad (e.g., a second and third pad (320b, 320c)) come into contact. For example, the second and third pins (420b, 420c) and the second and third pads (320b, 320c) may come into contact first, and after a predetermined delay occurs, the first pin (420a) and the first pad (320a) may come into contact. In response to the electrical connection of the first pin (420a) and the first pad (320a), an electrical current may be transmitted from the power cable (400) to the cable receiving portion (300). A signal can be input.

[0173] According to one embodiment, when the power cable (400) is connected to the cable receiving portion (300) due to the delay, the HMD device (e.g., the electronic device (101) of FIG. 1 and / or the HMD device (200) of FIG. 2) can stably receive an electric signal from an external power source. In order to generate a delay equal to a predetermined delay at the time when the first pin (420a) and the first pad (320a) come into contact with each other, the arrangement structure and shape of the first to third pads (320a, 320b, 320c) included in the connector pad (320) can be determined. The arrangement structure and shape of the first to third pads (320a, 320b, 320c) will be described below with reference to FIG. 10.

[0174] FIG. 10 is a front view of a connector pad assembly (310) (e.g., the connector pad assembly (310) of FIG. 5) and a connector pin assembly (410) (e.g., the connector pin assembly (410) of FIG. 6) according to one embodiment of the present disclosure.

[0175] (a) of FIG. 10 is a front view showing one surface of a connector pad (320) of a connector pad assembly (310) (e.g., connector pad (320) of FIG. 5) exposed, and (b) of FIG. 10 can be understood as a front view showing one surface of a connector pin (420) of a connector pin assembly (410) (e.g., connector pin (420) of FIG. 5) exposed.

[0176] The embodiment of FIG. 10 can be optionally combined with the embodiments of FIGS. 5 to 9.

[0177] Referring to FIG. 10, the connector pad assembly (310) may include a first pad (320a) (e.g., the first pad (320a) of FIG. 5), a second pad (320b) (e.g., the second pad (320b) of FIG. 5), and a third pad (320c) (e.g., the third pad (320c) of FIG. 5).

[0178] According to one embodiment, the first pad (320a) may be formed in a circular shape, and the second and third pads (320b, 320c) may be formed in a rectangular shape with rounded corners. However, the shapes of the first to third pads (320a, 320b, 320c) are not limited thereto, and may be implemented in various shapes. For example, the first pad (320a) may be implemented in a rectangular or square shape, and the second and third pads (320b, 320c) may be implemented in an oval or rectangular shape.

[0179] According to one embodiment, the first to third pads (320a, 320b, 320c) may be arranged in a third direction (e.g., +d3 or -d3).

[0180] According to one embodiment, the first to third pads (320a, 320b, 320c) may be arranged to be spaced apart from the bottom of the connector pad housing (311) by a predetermined distance in the vertical direction (e.g., in the +d1 or -d1 direction). For example, the bottom of the first pad (320a) may be arranged to be spaced apart from the bottom of the connector pad housing (311) by s1. For example, the bottom of the second pad (320b) may be arranged to be spaced apart from the bottom of the connector pad housing (311) by s2. For example, the bottom of the third pad (320c) may be arranged to be spaced apart from the bottom of the connector pad housing (311) by s3. For example, s1, s2, and s3 may be substantially the same.

[0181] According to one embodiment, the first pad (320a) may be disposed between the second pad (320b) and the third pad (320c). The first pad (320a) may be disposed on the lower side of the connector pad housing (311) (e.g., the connector pad housing (311) of FIG. 5), and the second and third pads (320b, 320c) may be disposed on both sides of the connector pad housing (311) and may be disposed in the vertical direction of the connector pad housing (311).

[0182] According to one embodiment, the first pad (320a) may be arranged to be spaced apart from the second and third pads (320b, 320c) in the horizontal direction by a predetermined distance. For example, the first pad (320a) may be arranged to be spaced apart from the second pad (320b) by a first distance (l1). For example, the first pad (320a) may be arranged to be spaced apart from the third pad (320c) by a second distance (l2).

[0183] According to one embodiment, the first pad (320a) may have a predetermined horizontal width (d1) and a predetermined vertical width (h1). For example, when the first pad (320a) is implemented in a shape of a circle or a square, the horizontal width (d1) and the vertical width (h1) may be substantially the same. However, the present invention is not limited to the illustrated shape, and when the first pad (320a) is implemented in a shape such as an oval or a rectangle, the horizontal width (d1) and the vertical width (h1) may be different from each other.

[0184] In one embodiment, the second pad (320b) and the third pad (320c) may have the same shape. For example, the horizontal width (w2) of the second pad (320b) and the horizontal width (w3) of the third pad (320c) may be substantially the same. For example, the vertical width (h2) of the second pad (320b) and the vertical width (h3) of the third pad (320c) may be substantially the same. For example, the areas exposed to the outside of the second pad (320b) and the third pad (320c) may be substantially the same.

[0185] According to one embodiment, the area of ​​the first pad (320a) exposed to the outside may be relatively small compared to the area of ​​the second and third pads (320b, 320c) exposed to the outside. For example, the area of ​​the first pad (320a) exposed to the outside may be approximately the area of ​​a circle formed by a diameter d1 ((1 / 2*d1) 2 ) can be defined. For example, the area of ​​the second pad (320b) exposed to the outside can be determined by the horizontal width (w2) and vertical width (h2) of the second pad (320b). For example, the area of ​​the third pad (320c) exposed to the outside can be determined by the horizontal width (w3) and vertical width (h3) of the third pad (320c).

[0186] According to one embodiment, the connector pin assembly (410) may include first to third pins (420a, 420b, 420c). The head portions (e.g., connector pin heads (421) of FIGS. 8 and 9) of the first to third pins (420a, 420b, 420c) positioned to be exposed to the outside of the connector pin assembly (410) may have a semi-spherical shape.

[0187] According to one embodiment, the first to third pins (420a, 420b, 420c) may be arranged to correspond to the first to third pads (320a, 320b, 320c). For example, the second and third pins (420b, 420c) may be arranged on both sides of the connector pin casing (411), and the first pin (420a) may be arranged between the second and third pins (420b, 420c).

[0188] According to one embodiment, the first to third pins (420a, 420b, 420c) may be arranged to be spaced apart from each other by a predetermined distance. For example, the first pin (420a) may be arranged to be spaced apart from the second pin (420b) by a first distance (l1'). For example, the first pin (420a) may be arranged to be spaced apart from the third pin (420c) by a second distance (l2').

[0189] According to one embodiment, each of the first to third pins (420a, 420b, 42c) may be spaced apart by the same distance as the first to third pads (320a, 320b, 320c). For example, a first distance (l1') at which the first pin (420a) and the second pin (420b) are spaced apart may be substantially the same as a first distance (l1) at which the first pad (320a) and the second pad (320b) are spaced apart. For example, a second distance (l2') at which the first pin (420a) and the third pin (420c) are spaced apart may be substantially the same as a second distance (l2) at which the first pad (320a) and the third pad (320c) are spaced apart.

[0190] According to one embodiment, the first to third pins (420a, 420b, 420c) may be arranged to be spaced apart from the bottom of the connector pin casing (411) by a predetermined distance in the vertical direction (e.g., in the +d1 or -d1 direction). For example, the bottom of the first pin (420a) may be arranged to be spaced apart from the bottom of the connector pin casing (411) by s1'. For example, the bottom of the second pin (420b) may be arranged to be spaced apart from the bottom of the connector pin casing (411) by s2'. For example, the bottom of the third pin (420c) may be arranged to be spaced apart from the bottom of the connector pin casing (411) by s3'. For example, s1', s2', and s3' may be substantially the same.

[0191] According to one embodiment, the distance s1 at which the lower end of the second pad (320a) is spaced from the lower end of the connector pad housing (311) may be substantially equal to the distance s1' at which the lower end of the first pin (420a) is spaced from the lower end of the connector pin casing (411).

[0192] According to one embodiment, the distance s2 at which the lower end of the second pad (320b) is spaced from the lower end of the connector pad housing (311) may be substantially equal to the distance s2' at which the lower end of the second pin (420b) is spaced from the lower end of the connector pin casing (411).

[0193] According to one embodiment, the distance s3 at which the lower end of the third pad (320c) is spaced from the lower end of the connector pad housing (311) may be substantially equal to the distance s3' at which the lower end of the third pin (420c) is spaced from the lower end of the connector pin casing (411).

[0194] According to one embodiment, the first pin (420a) may have a diameter of d1'. The diameter (d1') of the first pin (420a) may be the same as or different from the diameter (d1) of the first pad (320a). For example, the diameter (d1') of the first pin (420a) may be larger than the diameter (d1) of the first pad (320a). However, the present invention is not limited to what is illustrated, and the diameter (d1') of the first pin (420a) may be smaller than the diameter (d1) of the first pad (320a).

[0195] According to one embodiment, the second pin (420b) may have a diameter of w2'. The diameter (w2') of the second pin (420b) may be equal to or greater than the horizontal width (w2) of the second pad (320b).

[0196] In one embodiment, the diameter (w2') of the second pin (420b) may be substantially equal to the diameter (d1') of the first pin (420a).

[0197] According to one embodiment, the third pin (420c) may have a diameter of w3'. The diameter (w3') of the third pin (420c) may be equal to or greater than the horizontal width (w3) of the third pad (320c).

[0198] According to one embodiment, the diameter (w3') of the third pin (420c) may be substantially equal to the diameter (d1') of the first pin (420a).

[0199] According to one embodiment, when the power cable (400) is fastened to the cable receiving portion (300), the connector pin (420) of the connector pin assembly (410) and the connector pad (320) of the connector pad assembly (310) may be coupled while facing each other so as to make contact. For example, the power cable (400) may slide from the upper side to the lower side of the cable receiving portion (300), and the connector pin (420) of the connector pin assembly (410) and the connector pad (320) of the connector pad assembly (310) may slide so as to make contact with each other. When the power cable (400) is fastened to the cable receiving portion (300), the first pin (420a) and the first pad (320a) may make contact with each other with a predetermined delay after the second and third pins (420b and 420c) and the second and third pads (320b and 320c) make contact. In addition, when the power cable (400) is removed from the cable receiving portion (300), the first pin (420a) and the first pad (320a) may be released from contact first, and after a predetermined delay, the second and third pins (420b, 420c) and the second and third pads (320b, 320c) may be released from contact.

[0200] Although not shown, the connector pin (420) may have the same shape as the connector pad (320) of FIG. 10, and the connector pad (320) may have the same shape as the connector pin (410) of FIG. 10, thereby forming a delay for the point of contact between the communication line and the power line. For example, the first to third pads (320a, 320b, 320c) may have a hemispherical shape or a shape similar thereto as the first to third pins (420a, 420b, 420c) of FIG. 10, and the first to third pins (420a, 420b, 420c) may have shapes corresponding to the first to third pads (320a, 320b, 320c) of FIG. 10, respectively.

[0201] Also, although not shown, by forming the areas of the first to third pads (320a, 320b, 320c) to be substantially the same and forming the sizes of the head portions (421) of the first to third pins (420a, 420b, 420c) to be different, a delay can be formed for the timing of contact between the communication line and the power line. For example, by forming the areas where the first to third pads (320a, 320b, 320c) are exposed to the outside to be substantially the same and forming the contact area of ​​the first pin (420a) to be smaller than that of the second and third pins (420b, 420c), the power and GND lines can be contacted, and the communication line can be contacted after a predetermined delay.

[0202] Hereinafter, the relative positional relationship between the connector pin assembly (410) and the connector pad assembly (310) while the power cable (400) is fastened to the cable receiving portion (300) and / or the power cable (400) is removed from the cable receiving portion (300) will be described in FIG. 11.

[0203] FIG. 11 schematically illustrates the relative positional relationship between a connector pad assembly (310) (e.g., the connector pad assembly (310) of FIG. 5) and a connector pin assembly (410) (e.g., the connector pin assembly (410) of FIG. 6) according to one embodiment of the present disclosure.

[0204] FIG. 11 illustrates the relative positional relationship between the connector pad assembly (310) and the connector pin assembly (410) when a power cable (e.g., the power cable (400) of FIG. 2) is coupled to a cable receiving portion (e.g., the cable receiving portion (300) of FIG. 5) or when the power cable (400) is detached from the cable receiving portion (300). For example, the positional relationship according to the operation of coupling the power cable (400) to the cable receiving portion (300) may change in the order of (a), (b), and (c), and the positional relationship according to the operation of detaching the power cable (400) from the cable receiving portion (300) may change in the order of (c), (b), and (a).

[0205] The embodiment of FIG. 11 can be optionally combined with the embodiments of FIGS. 2 to 10.

[0206] Referring to FIG. 11, (a) illustrates a state in which a connector pad (320) and a connector pin (420) are not in contact, (b) illustrates a state in which only a part of a connector pad (320) (e.g., the second and third pads (320b, 320c)) and a part of a connector pin (420) (e.g., the second and third pins (420b, 420c)) are in contact, and (c) illustrates a state in which the connector pad (320) and the connector pin (420) are in complete contact.

[0207] According to one embodiment, as the power cable (400) is coupled to the cable receiving portion (300), the power cable (400) can slide from the upper side to the lower side of the cable receiving portion (300). In response to the power cable (400) sliding downward, the connector pin assembly (410) (e.g., the connector pin assembly (410) of FIG. 6) can move closer to the connector pad assembly (310). Therefore, in response to the power cable (400) being coupled to the cable receiving portion (300), the connector pin assembly (410) and the connector pad assembly (310) can transition to states in the order of (a), (b), and (c).

[0208] According to one embodiment, as the power cable (400) is removed from the cable receiving portion (300), the power cable (400) can slide upwardly of the cable receiving portion (300). In response to the power cable (400) sliding upwardly, the connector pin assembly (410) can move away from the connector pad assembly (310). Therefore, in response to the power cable (400) being removed from the cable receiving portion (300), the connector pin assembly (410) and the connector pad assembly (310) can transition to states in the order of (c), (b), and (a).

[0209] Referring to (b), the second and third pads (320b, 320c) and the second and third pins (420b, 420c) are in contact, respectively, and the first pad (320a) and the first pin (420a) are not in contact. The second and third pads (320b, 320c) and the second and third pins (420b, 420c) can slide downward while maintaining a state of contact from the time point at which contact is initiated in (b) to the time point at which the first to third pads (320a, 320b, 320c) and the first to third pins (420a, 420b, 420c) make contact, respectively, in (c).

[0210] According to one embodiment, when the state transitions from (a) to (b), the second pad (320b) and the second pin (420b) are in contact with each other, the third pad (320c) and the third pin (420c) are in contact with each other, but the first pad (320a) and the first pin (420a) are not in contact with each other, so that the HMD device (e.g., the electronic device (101) of FIG. 1 and / or the HMD device (200) of FIG. 2) can determine that the power cable (400) is in a disconnected state. Accordingly, in (b), the HMD device (200) can be understood as before it starts supplying external power from the power cable (400).

[0211] Referring to (c), the first to third pads (320a, 320b, 320c) and the first to third pins (420a, 420b, 420c) are in contact, respectively.

[0212] According to one embodiment, when the state transitions from (b) to (c), the HMD device (200) can determine that the power cable (400) is connected in response to the first pad (320a) and the first pin (420a) coming into contact with each other. By determining that the HMD device (200) is in the connected state, the external power supplied to the power cable (400) can be received as the second pad (320b) and the second pin (420b) come into contact, and the third pad (320c) and the third pin (420c) come into contact.

[0213] According to one embodiment, while the HMD device (200) sequentially transitions between states (a), (b), and (c), the second and third pads (320b, 320c) and the second and third pins (420b, 420c) are brought into contact and after a predetermined delay has elapsed, the first pad (320a) and the first pin (420a) are brought into contact, so that the first to third pads (320a, 320b, 320c) and the first to third pins (420a, 420b, 420c) can all be brought into contact. As a result, the HMD device (200) can receive external power at the time when the first pad (320a) and the first pin (420a) are connected. Therefore, the HMD device (200) of the present disclosure can receive a stable supply of electric signals by receiving power from the outside at the time when the power cable (400) is completely connected.

[0214] According to one embodiment, when the state transitions from (c) to (b), the first pad (320a) and the first pin (420a) may be separated from each other and the contact may be released. As the contact between the first pad (320a) and the first pin (420a) is released, the HMD device (200) may determine that the connection with the power cable (400) is released. Accordingly, even if the second and third pads (320b, 320c) and the second and third pins (420b, 420c) are in contact with each other, the HMD device (200) may stop supplying power from the outside through the power cable (400).

[0215] According to one embodiment, when the state transitions from (b) to (a), the second and third pads (320b, 320c) and the second and third pins (420b, 420c) may be separated from each other and the contact may be released.

[0216] According to one embodiment, the HMD device (200) can cut off the power supply from the outside when the contact between the first pad (320a) and the first pin (420a) is released. Accordingly, the HMD device (200) of the present disclosure can cut off the power supply when the removal of the power cable (400) is initiated and the contact between the first pad (320a) and the first pin (420a) is released.

[0217] According to one embodiment, the HMD device (200) can provide a fastening structure of a connector pad (320) and a connector pin (420) to stably perform power supply and cut-off according to fastening and disconnection of a power cable (400).

[0218] FIG. 12 is a front view of a connector pad assembly (310-1) (e.g., the connector pad assembly (310) of FIG. 4) and a connector pin assembly (410-1) (e.g., the connector pin assembly (410) of FIG. 6) according to one embodiment of the present disclosure.

[0219] (a) of FIG. 12 is a front view showing one surface of a connector pad (320-1) of a connector pad assembly (310-1) (e.g., connector pad (320) of FIG. 5) exposed, and (b) of FIG. 12 can be understood as a front view showing one surface of a connector pin (420-1) of a connector pin assembly (410-1) (e.g., connector pin (420) of FIG. 5) exposed.

[0220] The embodiment of FIG. 12 can be optionally combined with the embodiments of FIGS. 5 to 9.

[0221] FIG. 12 may be understood as illustrating an expanded embodiment of a connector pad assembly (310-1) and a connector pin assembly (410-1) included in a cable receiving portion (e.g., a cable receiving portion (300) of FIG. 4) and a power cable (e.g., a power cable (400) of FIG. 2) included in an HMD device of the present disclosure (e.g., an electronic device (101) of FIG. 1 and / or an HMD device (200) of FIG. 2), respectively. The connector pad assembly (310-1) and the connector pin assembly (410-1) illustrated in FIG. 12 are implemented such that the connector pads (320-1) and the connector pins (420-1) are arranged to correspond to each other, and the connector pads (320-1) and the connector pins (420-1) are connected in a predetermined order, and the functions of each of the connector pads (320-1) and the connector pins (420-1) are the same as in FIG. 10. Therefore, the explanation will focus on the differences related to the arrangement structure of the connector pad (320-1) and the connector pin (420-1).

[0222] Referring to (a) of FIG. 12, a connector pad assembly (310-1) may include a connector pad casing (311-1) and a connector pad (320-1). The connector pad (320-1) may include a first pad (320a-1), a second pad (320b-1), and a third pad (320c-1).

[0223] Referring to (b) of FIG. 12, a connector pin assembly (410-1) may include a connector pin casing (411-1) and a connector pin (420-1). The connector pin (420-1) may include a first pin (420a-1), a second pin (420b-1), and a third pin (420c-1).

[0224] In one embodiment, the first pad (320a-1) and the first pin (420a-1) may be implemented as CC terminals to provide device-to-device communication. For example, when the first pad (320a-1) and the first pin (420a-1) are connected, the HMD device (200) may determine that the power cable (400) is connected. For example, when the first pad (320a-1) and the first pin (420a-1) are disconnected, the HMD device (200) may determine that the power cable (400) is disconnected.

[0225] According to one embodiment, the second pad (320b-1) and the second pin (420b-1) may be implemented as power terminals (e.g., V_BUS terminals) to provide a path for supplying power from the outside.

[0226] According to one embodiment, the third pad (320c-1) and the third pin (420c-1) may be implemented as ground terminals to provide a grounding function.

[0227] According to one embodiment, the first pad (320a-1) may be disposed on the lower side of the connector pad casing (311-1). For example, the first pad (320a-1) may be positioned in a negative first direction (e.g., -d1) with respect to the second pad (320b-1) and the third pad (320c-1). For example, the first pad (320a-1) may have a rectangular or oval shape in which a horizontal width is longer than a vertical width. For example, the first pad (320a-1) may have a rectangular or oval shape in which a length in the third direction (e.g., +d3 or -d3 direction) is longer than a length in the first direction (e.g., +d1 or -d1 direction).

[0228] According to one embodiment, the second pad (320b-1) and the third pad (320c-1) may be positioned above the first pad (320a-1). For example, the first pad (320a-1) may be positioned in a positive first direction (e.g., +d1) with respect to the second pad (320b-1) and the third pad (320c-1). For example, the second pad (320b-1) and the third pad (320c-1) may have a rectangular or elliptical shape in which a vertical width is longer than a horizontal width. For example, the second pad (320b-1) and the third pad (320c-1) may have a rectangular or elliptical shape in which a length in the first direction (e.g., +d1 or -d1 direction) is longer than a length in the third direction (e.g., +d3 or -d3 direction).

[0229] According to one embodiment, the first to third pins (420a-1, 420b-1, 420c-1) may be arranged such that a hemispherical head portion (e.g., a connector pin head (421) of FIG. 7) is exposed to the outside of the connector pin casing (411-1). For example, the head portion (421) of the first to third pins (420a-1, 420b-1, 420c-1) may be formed to protrude in a second direction (e.g., +d2 or -d2 of FIG. 5).

[0230] According to one embodiment, as the power cable (400) is fastened from the upper side to the lower side (e.g., in the first direction) of the cable receiving portion (300), the connector pin assembly (410-1) can move closer to the connector pad assembly (310-1). In the process of the connector pin assembly (410-1) moving closer to the connector pad assembly (310-1), the first to third pads (320a-1, 320b-1, 320c-1) and the first to third pins (420a-1, 420b-1, 420c-1) can be connected in a predetermined order.

[0231] FIG. 13 schematically illustrates the relative positional relationship between a connector pad assembly (310-1) (e.g., the connector pad assembly (310-1) of FIG. 12) and a connector pin assembly (410-1) (e.g., the connector pin assembly (410-1) of FIG. 12) according to one embodiment of the present disclosure.

[0232] FIG. 13 illustrates the relative positional relationship between the connector pad assembly (310-1) and the connector pin assembly (410-1) when a power cable (e.g., the power cable (400) of FIG. 2) is coupled to a cable receiving portion (e.g., the cable receiving portion (300) of FIG. 5) or when the power cable (400) is detached from the cable receiving portion (300). For example, the positional relationship according to the operation of coupling the power cable (400) to the cable receiving portion (300) may change in the order of (a), (b), and (c), and the positional relationship according to the operation of detaching the power cable (400) from the cable receiving portion (300) may change in the order of (c), (b), and (a).

[0233] The embodiment of FIG. 13 can be optionally combined with the embodiment of FIG. 12.

[0234] Referring to FIG. 13, (a) illustrates a state in which a connector pad (320-1) and a connector pin (420-1) are not in contact, (b) illustrates a state in which only a part of a connector pad (320-1) (e.g., the second and third pads (320b-1, 320c-1)) and a part of a connector pin (420-1) (e.g., the second and third pins (420b-1, 420c-1)) are in contact, and (c) illustrates a state in which a connector pad (320-1) and a connector pin (420-1) are in complete contact.

[0235] According to one embodiment, as the power cable (400) is coupled to the cable receiving portion (300), the power cable (400) can slide from the upper side to the lower side of the cable receiving portion (300). In response to the power cable (400) sliding downward, the connector pin assembly (410-1) can move closer to the connector pad assembly (310-1). Therefore, in response to the power cable (400) being coupled to the cable receiving portion (300), the connector pin assembly (410-1) and the connector pad assembly (310-1) can transition states in the order of (a), (b), and (c).

[0236] According to one embodiment, as the power cable (400) is removed from the cable receiving portion (300), the power cable (400) can slide upwardly of the cable receiving portion (300). In response to the power cable (400) sliding upwardly, the connector pin assembly (410-1) can move away from the connector pad assembly (310-1). Therefore, in response to the power cable (400) being removed from the cable receiving portion (300), the connector pin assembly (410-1) and the connector pad assembly (310-1) can transition to states in the order of (c), (b), and (a).

[0237] Referring to (b), the second and third pads (320b-1, 320c-1) and the second and third pins (420b-1, 420c-1) are in contact, respectively, and the first pad (320a-1) and the first pin (420a-1) are not in contact.

[0238] According to one embodiment, when the state transitions from (a) to (b), the second pad (320b-1) and the second pin (420b-1) are in contact with each other, the third pad (320c-1) and the third pin (420c-1) are in contact with each other, but the first pad (320a-1) and the first pin (420a-1) are not in contact with each other, so that the HMD device (e.g., the electronic device (101) of FIG. 1 and / or the HMD device (200) of FIG. 2) can determine that the power cable (400) is in a disconnected state. Accordingly, in (b), the HMD device (200) can be understood as before it starts receiving external power from the power cable (400).

[0239] Referring to (c), the first to third pads (320a-1, 320b-1, 320c-1) and the first to third pins (420a-1, 420b-1, 420c-1) are in contact, respectively.

[0240] According to one embodiment, when the state transitions from (b) to (c), in response to the first pad (320a-1) and the first pin (420a-1) coming into contact with each other, the HMD device (200) can determine that the power cable (400) is connected. By determining that the HMD device (200) is in the connected state, the second pad (320b-1) and the second pin (420b-1) come into contact, and the third pad (320c-1) and the third pin (420c-1) come into contact, so that the HMD device (200) can receive external power supplied to the power cable (400).

[0241] According to one embodiment, while the HMD device (200) sequentially transitions between states (a), (b), and (c), the second and third pads (320b-1, 320c-1) and the second and third pins (420b-1, 420c-1) are brought into contact and after a predetermined delay has elapsed, the first pad (320a-1) and the first pin (420a-1) are brought into contact, so that the first to third pads (320a-1, 320b-1, 320c-1) and the first to third pins (420a-1, 420b-1, 420c-1) can all be brought into contact. As a result, the HMD device (200) can be supplied with external power at the time when the first pad (320a-1) and the first pin (420a-1) are connected. Accordingly, the HMD device (200) of the present disclosure can stably receive an electric signal by receiving power from the outside at the time when the power cable (400) is completely connected.

[0242] According to one embodiment, when the state transitions from (c) to (b), the first pad (320a-1) and the first pin (420a-1) may be separated from each other and the contact may be released. As the contact between the first pad (320a-1) and the first pin (420a-1) is released, the HMD device (200) may determine that the connection with the power cable (400) is released. Accordingly, even if the second and third pads (320b-1, 320c-1) and the second and third pins (420b-1, 420c-1) are in contact with each other, the HMD device (200) may stop supplying power from the outside through the power cable (400).

[0243] According to one embodiment, when the state transitions from (b) to (a), the second and third pads (320b-1, 320c-1) and the second and third pins (420b-1, 420c-1) may be separated from each other and the contact may be released.

[0244] According to one embodiment, the HMD device (200) can cut off the power supply from the outside at the point when the contact between the first pad (320a-1) and the first pin (420a-1) is released. Accordingly, the HMD device (200) of the present disclosure can cut off the power supply when the removal of the power cable (400) is initiated and the contact between the first pad (320a-1) and the first pin (420a-1) is released.

[0245] According to one embodiment, the HMD device (200) can provide a fastening structure of a connector pad (320-1) and a connector pin (420-1) to stably perform power supply and cut-off according to fastening and disconnection of a power cable (400).

[0246] FIG. 14 is a front view of a connector pad assembly (310-2) (e.g., the connector pad assembly (310) of FIG. 4) and a connector pin assembly (410-2) (e.g., the connector pin assembly (410) of FIG. 6) according to one embodiment of the present disclosure.

[0247] (a) of FIG. 14 is a front view showing one surface of a connector pad (320-2) of a connector pad assembly (310-2) (e.g., connector pad (320) of FIG. 5) exposed, and (b) of FIG. 12 can be understood as a front view showing one surface of a connector pin (420-2) of a connector pin assembly (410-2) (e.g., connector pin (420) of FIG. 5) exposed.

[0248] The embodiment of FIG. 14 can be optionally combined with the embodiments of FIGS. 5 to 9.

[0249] FIG. 14 may be understood as illustrating an expanded embodiment of a connector pad assembly (310-2) and a connector pin assembly (410-2) included in a cable receiving portion (e.g., a cable receiving portion (300) of FIG. 4) and a power cable (e.g., a power cable (400) of FIG. 2) included in an HMD device of the present disclosure (e.g., an electronic device (101) of FIG. 1 and / or an HMD device (200) of FIG. 2), respectively. The connector pad assembly (310-2) and the connector pin assembly (410-2) illustrated in FIG. 14 are implemented such that the connector pads (320-2) and the connector pins (420-2) are respectively arranged to correspond to each other, and the connector pads (320-2) and the connector pins (420-2) are connected in a predetermined order, and the functions of each of the connector pads (320-2) and the connector pins (420-2) are the same as in FIG. 10. Therefore, the explanation will focus on the differences related to the arrangement structure of the connector pad (320-2) and the connector pin (420-2).

[0250] Referring to (a) of FIG. 14, the connector pad assembly (310-2) may include a connector pad casing (311-2) and a connector pad (320-2). The connector pad (320-2) may include a first pad (320a-2), a second pad (320b-2), and a third pad (320c-2).

[0251] Referring to (b) of FIG. 14, the connector pin assembly (410-2) may include a connector pin casing (411-2) and a connector pin (420-2). The connector pin (420-2) may include a first pin (420a-2), a second pin (420b-2), and a third pin (420c-2).

[0252] In one embodiment, the first pad (320a-2) and the first pin (420a-2) may be implemented as CC terminals to provide device-to-device communication. For example, when the first pad (320a-2) and the first pin (420a-2) are connected, the HMD device (200) may determine that the power cable (400) is connected. For example, when the first pad (320a-2) and the first pin (420a-2) are disconnected, the HMD device (200) may determine that the power cable (400) is disconnected.

[0253] According to one embodiment, the second pad (320b-2) and the second pin (420b-2) may be implemented as power terminals (e.g., V_BUS terminals) to provide a path for supplying power from the outside.

[0254] According to one embodiment, the third pad (320c-2) and the third pin (420c-2) may be implemented as ground terminals to provide a grounding function.

[0255] According to one embodiment, the first to third pads (320a-2, 320b-2, 320c-2) may have a rectangular or oval shape with a horizontal width longer than a vertical width.

[0256] According to one embodiment, the first to third pads (320a-2, 320b-2, 320c-2) may be arranged in a vertical direction. For example, the first to third pads (320a-2, 320b-2, 320c-2) may be arranged in a first direction (e.g., +d1 or -d1 direction). For example, the second pad (320b-2) may be arranged on the upper side of the connector pad casing (311-2), and the third pad (320c-2) may be arranged on the lower side of the connector pad casing (311-2). For example, the first pad (320a-2) may be arranged between the second pad (320b-2) and the third pad (320c-2).

[0257] According to one embodiment, the width of the area where the first pad (320a-2) is exposed to the outside may be relatively small compared to the width of the area where the second and third pads (320b-2, 320c-2) are exposed to the outside.

[0258] According to one embodiment, the first to third pins (420a-2, 420b-2, 420c-2) may be arranged such that the hemispherical head portions (e.g., the connector pin head (421) of FIG. 7) are exposed to the outside of the connector pin casing (411-2). For example, the first to third pins (420a-2, 420b-2, 420c-2) may be arranged such that the hemispherical head portions (421) face the second direction (e.g., the +d2 or -d2 direction of FIG. 5).

[0259] According to one embodiment, the first to third pins (420a-2, 420b-2, 420c-2) may be arranged vertically. For example, the second pin (420b-2) may be arranged on the upper side of the connector pin casing (411-2), and the third pin (420c-2) may be arranged on the lower side of the connector pin casing (411-2). For example, the first pin (420a-2) may be arranged between the second pin (420b-2) and the third pin (420c-2).

[0260] According to one embodiment, the connector pad casing (311-2) and the connector pin casing (411-2) may have the same overall horizontal and vertical widths.

[0261] According to one embodiment, the connection order of the connector pad (320-2) and the connector pin (420-2) can be determined when connecting or disconnecting the power cable (400) depending on the spacing at which each of the connector pad (320-2) and the connector pin (420-2) is arranged.

[0262] According to one embodiment, each of the connector pads (320-2) and the connector pins (420-2) may be arranged at a predetermined interval. Hereinafter, for the convenience of explaining the positional relationship between the connector pads (320-2) and the connector pins (420-2), the positions of points corresponding to the upper and lower ends of the connector pad assembly (310-2) and the connector pin assembly (410-2) will be defined as follows.

[0263] Based on the first direction, the position of the point corresponding to the lowest end of the connector pad casing (311-2) can be defined as P0, the position of the point corresponding to the lower end of the third pad (320c-2) can be defined as P1, the position of the point corresponding to the upper end of the third pad (320c-2) can be defined as P2, the position of the point corresponding to the lower end of the first pad (320a-2) can be defined as P3, the position of the point corresponding to the upper end of the first pad (320a-2) can be defined as P4, the position of the point corresponding to the lower end of the second pad (320b-2) can be defined as P5, the position of the point corresponding to the upper end of the second pad (320b-2) can be defined as P6, and the position of the point corresponding to the upper end of the connector pad casing (311-2) can be defined as P7.

[0264] Based on the first direction, the position of the point corresponding to the lowest end of the connector pin casing (411-2) can be defined as P0, the position of the point corresponding to the lower end of the third pin (420c-2) can be defined as P1', the position of the point corresponding to the upper end of the third pin (420c-2) can be defined as P2', the position of the point corresponding to the lower end of the first pin (420a-2) can be defined as P3', the position of the point corresponding to the upper end of the first pin (420a-2) can be defined as P4', the position of the point corresponding to the lower end of the second pin (420b-2) can be defined as P5', the position of the point corresponding to the upper end of the second pin (420b-2) can be defined as P6', and the position of the point corresponding to the upper end of the connector pin casing (411-2) can be defined as P7.

[0265] Since the vertical widths of the connector pad casing (311-2) and the connector pin casing (411-2) correspond to each other (e.g., are the same), the position P0 of the point corresponding to the lowest end of the connector pad casing (311-2) and the connector pin casing (411-2) and the position P7 of the point corresponding to the highest end can be set to be the same based on the first direction.

[0266] According to one embodiment, the first to third pads (320a-2, 320b-2, 320c-2) and the first to third pins (420a-2, 420b-2, 420c-2) may be arranged to have the following relationships. For example, the spacing p1 between points P0 and P1 and the spacing p1' between points P0 and P1' may be substantially the same. For example, the spacing p2 between points P2 and P4 and the spacing p2' between points P2' and P3' may be substantially the same. For example, the spacing p3 between points P5 and P7 and the spacing p3' between points P5' and P7 may be substantially the same with respect to the first direction.

[0267] According to one embodiment, the separation distance between the first pad (320a-2) and the second pad (320b-2) may be set to the distance between points P4 and P5. The separation distance between the first pad (320a-2) and the third pad (320c-2) may be set to the distance between points P2 and P3.

[0268] According to one embodiment, the separation distance between the first pad (320a-2) and the second pad (320b-2) may be set to be substantially the same as the separation distance between the first pad (320a-2) and the third pad (320c-2).

[0269] According to one embodiment, the spacing between the first pin (420a-2) and the second pin (420b-2) may be set to the spacing between points P4' and P5'. The spacing between the first pin (420a-2) and the third pin (420c-2) may be set to the spacing between points P2' and P3'.

[0270] According to one embodiment, the first to third fins (420a-2, 420b-2, 420c-2) may be arranged such that the distance between the first fin (420a-2) and the second fin (420b-2) is shorter than the distance between the first fin (420a-2) and the third fin (420c-2). However, the present invention is not limited to what is illustrated, and the first to third fins (420a-2, 420b-2, 420c-2) may be arranged such that the distance between the first fin (420a-2) and the third fin (420c-2) is shorter than the distance between the first fin (420a-2) and the second fin (420b-2).

[0271] According to one embodiment, since the first to third pads (320a-2, 320b-2, 320c-2) and the first to third pins (420a-2, 420b-2, 420c-2) are arranged at predetermined intervals, when a power cable (e.g., power cable (400) of FIG. 2) is connected to a cable receiving portion (e.g., cable receiving portion (300) of FIG. 5), the connector pads (320-2) and the connector pins (420-2) can be connected in a predetermined order. This will be described in connection with FIG. 15.

[0272] Although not shown, the connector pin (420-2) has the same shape as the connector pad (320-2) of FIG. 14, and the connector pad (320-2) has the same shape as the connector pin (410-2) of FIG. 14, thereby forming a delay in the point of contact between the communication line and the power line. For example, the first to third pads (320a-2, 320b-2, 320c-2) may have a hemispherical shape or a shape similar thereto as the first to third pins (420a-2, 420b-2, 420c-2) illustrated in FIG. 14, and the first to third pins (420a-2, 420b-2, 420c-2) may have shapes corresponding to the first to third pads (320a-2, 320b-2, 320c-2) illustrated in FIG. 14, respectively.

[0273] FIG. 15 schematically illustrates the relative positional relationship between a connector pad assembly (310-2) (e.g., the connector pad assembly (310-2) of FIG. 14) and a connector pin assembly (410-2) (e.g., the connector pin assembly (410-2) of FIG. 14) according to one embodiment of the present disclosure.

[0274] FIG. 15 illustrates the relative positional relationship between the connector pad assembly (310-2) and the connector pin assembly (410-2) when a power cable (e.g., the power cable (400) of FIG. 2) is coupled to a cable receiving portion (e.g., the cable receiving portion (300) of FIG. 5) or when the power cable (400) is detached from the cable receiving portion (300). For example, the positional relationship according to the operation of coupling the power cable (400) to the cable receiving portion (300) may change in the order of (a), (b), and (c), and the positional relationship according to the operation of detaching the power cable (400) from the cable receiving portion (300) may change in the order of (c), (b), and (a).

[0275] The embodiment of FIG. 15 can be optionally combined with the embodiment of FIG. 14.

[0276] Referring to FIG. 15, (a) illustrates a state in which the connector pads (320-2) and the connector pins (420-2) are arranged so that they do not correspond to each other, (b) illustrates a state in which only a part of the connector pads (320-2) (e.g., the second and third pads (320b-2, 320c-2)) and a part of the connector pins (420-2) (e.g., the second and third pins (420b-2, 420c-2)) correspond to each other, and (c) illustrates a state in which the connector pads (320-2) and the connector pins (420-2) are in contact so that they completely correspond to each other.

[0277] According to one embodiment, as the power cable (400) is coupled to the cable receiving portion (300), the power cable (400) can slide from the upper side to the lower side of the cable receiving portion (300). In response to the power cable (400) sliding downward, the connector pin assembly (410-2) can move closer to the connector pad assembly (310-2). Therefore, in response to the power cable (400) being coupled to the cable receiving portion (300), the connector pin assembly (410-2) and the connector pad assembly (310-2) can transition states in the order of (a), (b), and (c).

[0278] According to one embodiment, as the power cable (400) is removed from the cable receiving portion (300), the power cable (400) can slide upwardly of the cable receiving portion (300). In response to the power cable (400) sliding upwardly, the connector pin assembly (410-2) can move away from the connector pad assembly (310-2). Therefore, in response to the power cable (400) being removed from the cable receiving portion (300), the connector pin assembly (410-2) and the connector pad assembly (310-2) can transition to states in the order of (c), (b), and (a).

[0279] Referring to (b), the second and third pads (320b-2, 320c-2) and the second and third pins (420b-1, 420c-2) are in contact, respectively, and the first pad (320a-2) and the first pin (420a-2) are not in contact.

[0280] According to one embodiment, when the state transitions from (a) to (b), the second pad (320b-2) and the second pin (420b-2) are in contact with each other, the third pad (320c-2) and the third pin (420c-2) are in contact with each other, but the first pad (320a-2) and the first pin (420a-2) are not in contact with each other, so that the HMD device (e.g., the electronic device (101) of FIG. 1 and / or the HMD device (200) of FIG. 2) can determine that the power cable (400) is in a disconnected state. Accordingly, in (b), the HMD device (200) can be understood as before it starts supplying external power from the power cable (400).

[0281] Referring to (c), the first to third pads (320a-2, 320b-2, 320c-2) and the first to third pins (420a-2, 420b-2, 420c-2) are in contact, respectively.

[0282] According to one embodiment, when the state transitions from (b) to (c), the HMD device (200) can determine that the power cable (400) is connected in response to the first pad (320a-2) and the first pin (420a-2) coming into contact with each other. By determining that the HMD device (200) is in the connected state, the second pad (320b-2) and the second pin (420b-2) come into contact, and the third pad (320c-2) and the third pin (420c-2) come into contact, so that the HMD device (200) can receive external power supplied to the power cable (400).

[0283] According to one embodiment, while the HMD device (200) sequentially transitions between states (a), (b), and (c), the second and third pads (320b-2, 320c-2) and the second and third pins (420b-2, 420c-2) are brought into contact and after a predetermined delay has elapsed, the first pad (320a-2) and the first pin (420a-2) are brought into contact, so that the first to third pads (320a-2, 320b-2, 320c-2) and the first to third pins (420a-2, 420b-2, 420c-2) can all be brought into contact. As a result, the HMD device (200) can be supplied with external power at the time when the first pad (320a-2) and the first pin (420a-2) are connected. Accordingly, the HMD device (200) of the present disclosure can stably receive an electric signal by receiving power from the outside at the time when the power cable (400) is completely connected.

[0284] According to one embodiment, when the state transitions from (c) to (b), the first pad (320a-2) and the first pin (420a-2) may be separated from each other and the contact may be released. As the contact between the first pad (320a-2) and the first pin (420a-2) is released, the HMD device (200) may determine that the connection with the power cable (400) is released. Accordingly, even if the second and third pads (320b-2, 320c-2) and the second and third pins (420b-2, 420c-2) are in contact with each other, the HMD device (200) may stop supplying power from the outside through the power cable (400).

[0285] According to one embodiment, when the state transitions from (b) to (a), the second and third pads (320b-2, 320c-2) and the second and third pins (420b-2, 420c-2) may be separated from each other and the contact may be released.

[0286] According to one embodiment, the HMD device (200) can cut off the power supply from the outside at the point when the contact between the first pad (320a-2) and the first pin (420a-2) is released. Accordingly, the HMD device (200) of the present disclosure can cut off the power supply when the removal of the power cable (400) is initiated and the contact between the first pad (320a-2) and the first pin (420a-2) is released.

[0287] According to one embodiment, the HMD device (200) can provide a fastening structure of a connector pad (320-2) and a connector pin (420-2) to stably perform power supply and cut-off according to fastening and disconnection of a power cable (400).

[0288] FIG. 16 is a front view of a connector pad assembly (310-3) (e.g., the connector pad assembly (310) of FIG. 4) and a connector pin assembly (410-3) (e.g., the connector pin assembly (410) of FIG. 6) according to one embodiment of the present disclosure.

[0289] (a) of FIG. 16 is a front view showing one surface of a connector pad (320-3) of a connector pad assembly (310-3) (e.g., connector pad (320) of FIG. 5) exposed, and (b) of FIG. 12 can be understood as a front view showing one surface of a connector pin (420-3) of a connector pin assembly (410-3) (e.g., connector pin (420) of FIG. 5) exposed.

[0290] The embodiment of FIG. 16 can be optionally combined with the embodiments of FIGS. 5 to 9.

[0291] FIG. 16 may be understood as illustrating an expanded embodiment of a connector pad assembly (310-3) and a connector pin assembly (410-3) included in a cable receiving portion (e.g., a cable receiving portion (300) of FIG. 4) and a power cable (e.g., a power cable (400) of FIG. 2) included in an HMD device of the present disclosure (e.g., an electronic device (101) of FIG. 1 and / or an HMD device (200) of FIG. 2), respectively. The connector pad assembly (310-3) and the connector pin assembly (410-3) illustrated in FIG. 14 are implemented such that the connector pads (320-3) and the connector pins (420-3) are arranged to correspond to each other, and the connector pads (320-3) and the connector pins (420-3) are connected in a predetermined order, and the functions of each of the connector pads (320-3) and the connector pins (420-3) are the same as in FIG. 10. Therefore, the explanation will focus on the differences related to the arrangement structure of the connector pad (320-3) and the connector pin (420-3).

[0292] Referring to (a) of FIG. 16, the connector pad assembly (310-3) may include a connector pad casing (311-3) and a connector pad (320-3). The connector pad (320-3) may include a first pad (320a-3), a second pad (320b-3), and a third pad (320c-3).

[0293] Referring to (b) of FIG. 16, the connector pin assembly (410-3) may include a connector pin casing (411-3) and a connector pin (420-3). The connector pin (420-3) may include a first pin (420a-3), a second pin (420b-3), and a third pin (420c-3).

[0294] In one embodiment, the first pad (320a-3) and the first pin (420a-3) may be implemented as CC terminals to provide device-to-device communication. For example, when the first pad (320a-3) and the first pin (420a-3) are connected, the HMD device (200) may determine that the power cable (400) is connected. For example, when the first pad (320a-3) and the first pin (420a-3) are disconnected, the HMD device (200) may determine that the power cable (400) is disconnected.

[0295] According to one embodiment, the second pad (320b-3) and the second pin (420b-3) may be implemented as power terminals (e.g., V_BUS terminals) to provide a path for supplying power from the outside.

[0296] According to one embodiment, the third pad (320c-3) and the third pin (420c-3) may be implemented as ground terminals to provide a grounding function.

[0297] According to one embodiment, the first to third pads (320a-3, 320b-3, 320c-3) may have a rectangular or oval shape with a horizontal width longer than a vertical width.

[0298] According to one embodiment, the first to third pads (320a-3, 320b-3, 320c-3) may be arranged in a vertical direction. For example, the first to third pads (320a-3, 320b-3, 320c-3) may be arranged in a first direction (e.g., in the +d1 or -d1 direction). For example, the third pad (320c-3) may be arranged on the upper side (e.g., in the +d1 direction) of the connector pad casing (311-3), and the first pad (320a-3) may be arranged on the lower side (e.g., in the -d1 direction) of the connector pad casing (311-3). For example, the third pad (320c-2) may be arranged between the second pad (320b-2) and the first pad (320a-2).

[0299] According to one embodiment, the width of the area where the first pad (320a-3) is exposed to the outside may be relatively small compared to the width of the area where the second and third pads (320b-3, 320c-3) are exposed to the outside.

[0300] According to one embodiment, the first to third pins (420a-3, 420b-3, 420c-3) may be arranged such that the hemispherical head portions (e.g., the connector pin head (421) of FIG. 7) are exposed to the outside of the connector pin casing (411-3). For example, the first to third pins (420a-3, 420b-3, 420c-3) may be arranged such that the hemispherical head portions (421) face the second direction (e.g., the +d2 or -d2 direction of FIG. 5).

[0301] According to one embodiment, the first to third pins (420a-3, 420b-3, 420c-3) may be arranged in a vertical direction. For example, the third pin (420c-3) may be arranged on the upper side (e.g., in the +d1 direction) of the connector pin casing (411-3), and the first pin (420a-3) may be arranged on the lower side (e.g., in the -d1 direction) of the connector pin casing (411-3). For example, the third pin (420c-3) may be arranged between the second pin (420b-3) and the first pin (420a-3).

[0302] According to one embodiment, the connector pad casing (311-3) and the connector pin casing (411-2) may have the same overall horizontal and vertical widths.

[0303] According to one embodiment, the connection order of the connector pad (320-3) and the connector pin (420-3) can be determined when connecting or disconnecting the power cable (400) depending on the spacing at which each of the connector pad (320-3) and the connector pin (420-3) is arranged.

[0304] According to one embodiment, each of the connector pad (320-3) and the connector pin (420-3) may be positioned at a predetermined interval. Hereinafter, for the convenience of explaining the positional relationship between the connector pad (320-3) and the connector pin (420-3), the positions of points corresponding to the upper and lower ends of the connector pad assembly (310-3) and the connector pin assembly (410-3) will be defined as follows.

[0305] Based on the first direction, the position of the point corresponding to the lowest end of the connector pad casing (311-3) can be defined as Q0, the position of the point corresponding to the lower end of the first pad (320a-3) can be defined as Q1, the position of the point corresponding to the upper end of the first pad (320a-3) can be defined as Q2, the position of the point corresponding to the lower end of the third pad (320c-3) can be defined as Q3, the position of the point corresponding to the upper end of the third pad (320c-3) can be defined as Q4, the position of the point corresponding to the lower end of the second pad (320b-3) can be defined as Q5, the position of the point corresponding to the upper end of the second pad (320b-3) can be defined as Q6, and the position of the point corresponding to the upper end of the connector pad casing (311-3) can be defined as Q7.

[0306] Based on the first direction, the position of the point corresponding to the lowest end of the connector pin casing (411-3) can be defined as Q0, the position of the point corresponding to the lower end of the first pin (420a-3) can be defined as Q1', the position of the point corresponding to the upper end of the first pin (420a-3) can be defined as Q2', the position of the point corresponding to the lower end of the third pin (420c-3) can be defined as Q3', the position of the point corresponding to the upper end of the third pin (420c-3) can be defined as Q4', the position of the point corresponding to the lower end of the second pin (420b-3) can be defined as Q5', the position of the point corresponding to the upper end of the second pin (420b-3) can be defined as Q6', and the position of the point corresponding to the upper end of the connector pin casing (411-3) can be defined as Q7.

[0307] Since the vertical widths of the connector pad casing (311-3) and the connector pin casing (411-3) correspond to each other (e.g., are the same), the position Q0 of the point corresponding to the lowest end of the connector pad casing (311-3) and the connector pin casing (411-3) and the position Q7 of the point corresponding to the highest end can be set to be the same based on the first direction.

[0308] According to one embodiment, the first to third pads (320a-3, 320b-3, 320c-3) and the first to third pins (420a-3, 420b-3, 420c-3) may be arranged to have the following relationships. For example, the spacing q1 between points Q0 and Q1 and the spacing q1' between points Q0 and Q1' may be substantially the same. For example, the spacing q2 between points Q1 and Q3 and the spacing q2' between points Q1' and Q3' may be substantially the same. For example, the spacing q3 between points Q5 and Q7 and the spacing q3' between points Q5' and Q7 may be substantially the same.

[0309] According to one embodiment, since the first to third pads (320a-3, 320b-3, 320c-3) and the first to third pins (420a-3, 420b-3, 420c-3) are arranged at predetermined intervals, when a power cable (e.g., power cable (400) of FIG. 2) is connected to a cable receiving portion (e.g., cable receiving portion (300) of FIG. 5), the connector pads (320-3) and the connector pins (420-3) can be connected in a predetermined order. This will be described in connection with FIG. 17.

[0310] According to one embodiment, either the second pad (320b-3) or the third pad (320c-3) may be positioned between the other of the second pad (320b-3) or the third pad (320c-3) and the first pad (320a-3). For example, referring to FIG. 16, the second pad (320b-3) may be positioned between the first pad (320a-3) and the third pad (320c-3). However, the present invention is not limited to what is illustrated, and the third pad (320c-3) may also be positioned between the first pad (320a-3) and the second pad (320b-3).

[0311] According to one embodiment, one of the second pin (420b-3) and the third pin (420c-3) may be positioned between the other of the second pin (420b-3) and the third pin (420c-3) and the first pin (420a-3). For example, referring to FIG. 16, the second pin (420b-3) may be positioned between the first pin (420a-3) and the third pin (420c-3). However, the present invention is not limited to what is illustrated, and the third pin (420c-3) may also be positioned between the first pin (420a-3) and the second pin (420b-3).

[0312] According to one embodiment, the distance between the first pin (420a-3) and a pin (e.g., the second pin (420b-3) of FIG. 16) positioned in close proximity to the first pin (420a-3) may be shorter than the distance between the second pin (420b-3) and the third pin (420c-3).

[0313] According to one embodiment, the separation distance between the first pin (420a-3) and the second pin (420b-3) may be set to the distance between points Q2' and Q3'. The separation distance between the second pin (420b-3) and the third pin (420c-3) may be set to the distance between points Q4' and Q5'. The distance between points Q2' and Q3' may be set to be shorter than the distance between points Q4' and Q5'. However, not limited to what is shown, if the pin arranged close to the first pin (420a-3) is the third pin (420c-3), the first to third pins (420a-3, 420b-3, 420c-3) may be arranged so that the distance between the first pin (420a-3) and the third pin (420c-3) is shorter than the distance between the second pin (420b-3) and the third pin (420c-3).

[0314] Although not shown, a delay can be formed for the point of contact between the communication line and the power line by the connector pin (420-3) having the same shape as the connector pad (320-3) of FIG. 14 and the connector pad (320-3) having the same shape as the connector pin (410-3) of FIG. 16. For example, the first to third pads (320a-3, 320b-3, 320c-3) may have a hemispherical shape or a shape similar thereto, such as the first to third pins (420a-3, 420b-3, 420c-3) illustrated in FIG. 14, and the first to third pins (420a-3, 420b-3, 420c-3) may have shapes corresponding to the first to third pads (320a-3, 320b-3, 320c-3) illustrated in FIG. 14, respectively.

[0315] FIG. 17 schematically illustrates the relative positional relationship between a connector pad assembly (310-3) (e.g., the connector pad assembly (310-3) of FIG. 16) and a connector pin assembly (410-3) (e.g., the connector pin assembly (410-3) of FIG. 16) according to one embodiment of the present disclosure.

[0316] FIG. 17 illustrates the relative positional relationship between the connector pad assembly (310-3) and the connector pin assembly (410-3) when a power cable (e.g., the power cable (400) of FIG. 2) is coupled to a cable receiving portion (e.g., the cable receiving portion (300) of FIG. 5) or when the power cable (400) is detached from the cable receiving portion (300). For example, the positional relationship according to the operation of coupling the power cable (400) to the cable receiving portion (300) may change in the order of (a), (b), and (c), and the positional relationship according to the operation of detaching the power cable (400) from the cable receiving portion (300) may change in the order of (c), (b), and (a).

[0317] The embodiment of FIG. 17 can be optionally combined with the embodiment of FIG. 16.

[0318] Referring to FIG. 17, (a) illustrates a state in which the connector pads (320-3) and the connector pins (420-3) are arranged so that they do not correspond to each other, (b) illustrates a state in which only a part of the connector pads (320-1) (e.g., the second and third pads (320b-3, 320c-3)) and a part of the connector pins (420-3) (e.g., the second and third pins (420b-3, 420c-3)) correspond to each other, and (c) illustrates a state in which the connector pads (320-3) and the connector pins (420-3) are in contact so that they completely correspond to each other.

[0319] According to one embodiment, as the power cable (400) is coupled to the cable receiving portion (300), the power cable (400) can slide from the upper side to the lower side of the cable receiving portion (300). In response to the power cable (400) sliding downward, the connector pin assembly (410-3) can move closer to the connector pad assembly (310-3). Therefore, in response to the power cable (400) being coupled to the cable receiving portion (300), the connector pin assembly (410-2) and the connector pad assembly (310-2) can transition states in the order of (a), (b), and (c).

[0320] Referring to (b), the second and third pads (320b-3, 320c-3) and the second and third pins (420b-1, 420c-3) are in contact, respectively, and the first pad (320a-3) and the first pin (420a-3) are not in contact.

[0321] According to one embodiment, when the state transitions from (a) to (b), the second pad (320b-3) and the second pin (420b-3) are in contact with each other, the third pad (320c-3) and the third pin (420c-3) are in contact with each other, but the first pad (320a-3) and the first pin (420a-3) are not in contact with each other, so that the HMD device (e.g., the electronic device (101) of FIG. 1 and / or the HMD device (200) of FIG. 2) can determine that the power cable (400) is in a disconnected state. Accordingly, in (b), the HMD device (200) can be understood as before starting to supply external power from the power cable (400).

[0322] Referring to (c), the first to third pads (320a-3, 320b-3, 320c-3) and the first to third pins (420a-3, 420b-3, 420c-3) are in contact, respectively.

[0323] According to one embodiment, when the state transitions from (b) to (c), the HMD device (200) can determine that the power cable (400) is connected in response to the first pad (320a-3) and the first pin (420a-3) coming into contact with each other. By determining that the HMD device (200) is in the connected state, the second pad (320b-3) and the second pin (420b-3) come into contact, and the third pad (320c-3) and the third pin (420c-3) come into contact, so that the HMD device (200) can receive external power supplied to the power cable (400).

[0324] According to one embodiment, while the HMD device (200) sequentially transitions between states (a), (b), and (c), the second and third pads (320b-3, 320c-3) and the second and third pins (420b-3, 420c-3) are brought into contact and after a predetermined delay has elapsed, the first pad (320a-3) and the first pin (420a-3) are brought into contact, so that the first to third pads (320a-3, 320b-3, 320c-3) and the first to third pins (420a-3, 420b-3, 420c-3) can all be brought into contact. As a result, the HMD device (200) can be supplied with external power at the time when the first pad (320a-3) and the first pin (420a-3) are connected. Accordingly, the HMD device (200) of the present disclosure can stably receive an electric signal by receiving power from the outside at the time when the power cable (400) is completely connected.

[0325] According to one embodiment, when the state transitions from (c) to (b), the first pad (320a-3) and the first pin (420a-3) may be separated from each other and the contact may be released. As the contact between the first pad (320a-3) and the first pin (420a-3) is released, the HMD device (200) may determine that the connection with the power cable (400) is released. Accordingly, even if the second and third pads (320b-3, 320c-3) and the second and third pins (420b-3, 420c-3) are in contact with each other, the HMD device (200) may stop supplying power from the outside through the power cable (400).

[0326] According to one embodiment, when the state transitions from (b) to (a), the second and third pads (320b-3, 320c-3) and the second and third pins (420b-3, 420c-3) may be separated from each other and the contact may be released.

[0327] According to one embodiment, the HMD device (200) can cut off the power supply from the outside at the point when the contact between the first pad (320a-3) and the first pin (420a-3) is released. Accordingly, the HMD device (200) of the present disclosure can cut off the power supply when the removal of the power cable (400) is initiated and the contact between the first pad (320a-3) and the first pin (420a-3) is released.

[0328] According to one embodiment, the HMD device (200) can provide a fastening structure of a connector pad (320-3) and a connector pin (420-3) to stably perform power supply and cut-off according to fastening and disconnection of a power cable (400).

[0329] A head mounted display device (200) according to one embodiment of the present disclosure (e.g., the electronic device (101) of FIG. 1 and / or the head mounted display device (200) of FIG. 2, hereinafter referred to as an HMD device (200)) can provide a stable connection with a power cable (e.g., the power cable (400) of FIG. 2) that supplies external power.

[0330] An HMD device (200) according to one embodiment of the present disclosure can be supplied with power after the power cable (400) is fully connected and the connector pin (e.g., the connector pin (420) of FIG. 5) and the connector pad (e.g., the connector pad (320) of FIG. 4) are fully connected.

[0331] An HMD device (200) according to one embodiment of the present disclosure can preferentially cut off the power supply between the connector pin (420) and the connector pad (320) when the removal of the power cable (400) is initiated.

[0332] An HMD device (200) according to one embodiment of the present disclosure can minimize damage to terminals caused by arc generation due to momentary electrical contact when a power cable (400) is connected or disconnected.
