Description

Technical Field

[0001] This invention relates to a PCB (Printed Circuit Board) clip, printed circuit boards including the clip, and electronic devices thereof. More specifically, it relates to a PCB clip that can fix a printed circuit board to a module cover while simultaneously combining dissimilar components such as connector brackets, heat sinks, or back covers. The invention also relates to printed circuit boards and electronic devices thereof. Background Technology

[0002] Printed circuit boards (PCBs), as core components of electronic devices, play a crucial role in ensuring electrical connections between electronic components. In recent years, with the miniaturization and increasing functionality of electronic devices, the circuit patterns on PCBs have become more intricate, and the number and variety of electronic components they house have also increased. Consequently, the assembly process for PCBs demands high precision and reliability, while existing assembly methods, primarily based on manual labor, have limitations in terms of production efficiency and quality management.

[0003] In existing printed circuit board (PCB) assembly processes, components are primarily inserted manually by operators or installed using semi-automatic equipment. However, this method can introduce quality deviations depending on the operator's skill level and is constrained by production speed during mass production. Furthermore, due to the miniaturization and high integration of electronic components, it is becoming increasingly difficult for operators to visually identify and accurately place components.

[0004] To address these issues, while surface mount technology (SMT) machines or automated mounting robots have been introduced, existing equipment is optimized for specific components or prescribed circuit patterns, limiting its ability to meet the design requirements of various electronic devices. This is particularly problematic in customized electronic devices or small-batch, multi-variety production environments, where reduced production efficiency and time-consuming equipment replacement and configuration changes are prevalent.

[0005] Therefore, the demand for technology that can use robots to automatically assemble printed circuit boards is increasing. This technology combines artificial intelligence, image recognition, and precision control to achieve automatic identification and precise placement of components, thereby improving production efficiency, reducing labor costs, and further enabling the stable production of high-quality electronic devices.

[0006] On the other hand, in electronic devices, in addition to printed circuit boards (PCBs), various other components are assembled together, such as brackets for mounting external connectors, heat sinks for dissipating heat from heat-generating components, and back covers that form the appearance of the electronic device. In existing technology, to secure these components to the PCB, separate fastening holes or fastening structures are typically formed within the PCB itself. For example, a method is used where a hook for mounting an external connector is inserted into and secured to a separate hook hole formed in the PCB.

[0007] However, as mentioned above, if mounting holes for securing individual components are formed separately on the printed circuit board, the mountable area of ​​the printed circuit board decreases, reducing the area occupied by the corresponding mounting holes. This leads to issues with miniaturization of the printed circuit board and component mounting efficiency. Furthermore, having separate clamps for securing the printed circuit board to the module cover and separate fastening structures for securing different components to the printed circuit board results in an increase in the number of components and assembly time. Summary of the Invention

[0008] The present invention is proposed to solve the above-mentioned problems. Its purpose is to provide a PCB clip, a printed circuit board including the PCB clip, and an electronic device that can combine dissimilar components such as connector brackets, heat sinks, or back covers without adding separate fastening holes to the printed circuit board for securely fixing the printed circuit board to the module cover and fixing dissimilar components.

[0009] To address the aforementioned problems, an electronic device according to an embodiment of the present invention may include: a module cover; A printed circuit board includes a board and a PCB clamp. The board has a clamping hole and includes a first side on which electronic components are mounted and a second side opposite to a module cover. The PCB clamp is mounted in the clamping hole and fastened to different components on the first and second sides of the board, respectively. The PCB clamp may include: a retaining plate covering at least a portion of the clamping hole and located on the first side, including a connecting portion; a fixing portion connected to the periphery of the retaining plate and fastened to at least a portion of the periphery of the clamping hole; and an elastic clip connected to at least one of the retaining plate or the fixing portion and protruding toward the second side of the board to engage with the module cover.

[0010] The joint may include one of the following shapes: a square hole, a circular hole, or a groove open on one side.

[0011] The printed circuit board may include a plurality of external connectors mounted on one side of the board, and may include a connector bracket fastened to one side of the board; the connector bracket may include: a plurality of connector holes formed at positions corresponding to the plurality of external connectors; and a bracket hook protruding toward the board and engaging with the joint.

[0012] The electronic device may further include a rear cover that covers the first side of the printed circuit board and is fastened to the module cover, and the printed circuit board may include a fastening hook that is fastened to the joint and engages with the rear cover hole of the rear cover.

[0013] The printed circuit board may include: a heat sink covering at least a portion of a first side of the board; and a heat sink fastener penetrating the heat sink and engaging with the joint.

[0014] The elastic clip can be fitted with the module cover in the vertical direction, and then slide along the surface direction to be fastened to the module cover.

[0015] The PCB clamp may further include a first connecting part that connects the retaining plate and the elastic clamp, or a second connecting part that connects the fixing part and the elastic clamp.

[0016] The fixing parts can be located on opposite sides of each other in the periphery of the clamp hole.

[0017] A PCB clamp according to another embodiment of the present invention is mounted in the clamp hole of a board having a clamp hole, and may include: a retaining plate covering at least a portion of the clamp hole and including a connecting portion; a fixing portion connected to the periphery of the retaining plate and fastened to at least a portion of the periphery of the clamp hole; and an elastic clamp connected to at least one of the retaining plate or the fixing portion, and extending through the clamp hole and protruding in the opposite direction to the retaining plate.

[0018] A printed circuit board according to another embodiment of the present invention may include: a board having a clamping hole and including a first side on which electronic components are mounted and a second side opposite to the first side; and a PCB clamp mounted in the clamping hole and fastened to different components on the first side and the second side of the board, respectively.

[0019] According to the present invention, the PCB clamp can simultaneously perform the functions of fixing the printed circuit board to the module cover and combining dissimilar components such as connector brackets, heat sinks or back covers. Therefore, there is no need to form separate fastening holes for fixing dissimilar components on the printed circuit board, thereby ensuring the mounting area of ​​the printed circuit board and achieving miniaturization.

[0020] In addition, since the PCB clamp's elastic clamp is slidably moved and secured after it mates with the module cover in the vertical direction, there is no need for separate fastening components such as screws. The printed circuit board can be automatically assembled onto the module cover by using robots, thereby simplifying the assembly process and improving production efficiency.

[0021] In addition, a PCB clip can be used to fix printed circuit boards and dissimilar components, thereby reducing the number of components and assembly time, and also helping to make electronic devices thinner.

[0022] The scope of application of this invention will become clearer through the following detailed description. However, those skilled in the art will readily understand various changes and modifications within the spirit and scope of this invention, and therefore it should be understood that the detailed description and specific implementations such as the preferred embodiments of the invention are merely exemplary.

Detailed Implementation

[0032] The embodiments disclosed in this specification will now be described in detail with reference to the accompanying drawings. Unless otherwise specified in the drawing numbers, the same or similar constituent elements are given the same reference numerals, and repeated descriptions thereof are omitted. The suffixes "module" and "part" used for constituent elements in the following description are merely for ease of writing and do not inherently distinguish one another.

Additionally, the accompanying drawings are only for aiding understanding of the embodiments disclosed in this specification and should be understood as not being limited by the drawings, but including all modifications, equivalents, and substitutions within the scope and technical range of the invention.

[0033] Terms such as "first," "second," etc., which include ordinal numbers, can be used to describe various constituent elements, but these constituent elements are not limited to these terms. These terms are only used to distinguish one constituent element from another.

[0034] When it is mentioned that a constituent element is "connected" or "linked" to another constituent element, it should be understood that it can be directly connected or linked to the other constituent element, but there may also be other constituent elements in between.

[0035] Unless the context clearly indicates otherwise, singular expressions include plural expressions.

[0036] In this application, the terms “comprising” or “having” should be understood as being intended to describe the presence of features, figures, steps, actions, constituent elements, components or combinations thereof as described in this specification, rather than as being intended to pre-exclude the presence or additional possibility of more than one other feature, figure, step, action, constituent element, component or combination thereof.

[0037] Figure 1 An example of an electronic device 100 according to an embodiment of the present invention is shown in a perspective view of a display device 100.

[0038] The electronic device 100 of the present invention includes various electronic devices having a printed circuit board 180. In particular, the present invention enables the electronic device 100 to have a thinner thickness and enables the automation of the installation of the printed circuit board 180, thereby maximizing its effect when applied to thin electronic devices such as display devices. Hereinafter, the description will be based on a display device.

[0039] Reference Figure 1 The display device 100 may have a rectangular body comprising a pair of long sides LS1, LS2 and a pair of short sides SS1, SS2. The long and short sides may be referred to as the edges of the display device 100.

[0040] The points where the long side and the short side intersect can be called angles C1, C2, C3, and C4.

[0041] Although the accompanying drawings show a long side extending horizontally and a short side extending vertically, the lengths of the long and short sides can be the same, and it is also possible for the long side to be arranged vertically.

[0042] The first direction DR1 is the horizontal direction LR of the display device 100. In this embodiment, it is the same as the direction parallel to the long side LS1 and LS2.

[0043] The second direction DR2 can be the vertical direction UD of the display device 100. In this embodiment, it can be a direction parallel to the short sides SS1 and SS2. The third direction DR3 can be a direction perpendicular to the first direction DR1 and / or the second direction DR2.

[0044] Figure 1 The display device shown can be arranged either horizontally along its long side or vertically along its length.

[0045] The side on which the display device 100 displays an image may be referred to as the front or front side. The side on which the image cannot be viewed when the display device 100 displays an image may be referred to as the back or back side.

[0046] The display panel 110 may include a liquid crystal display (LCD), a light-emitting diode (LED), an organic light-emitting diode (OLED), etc.

[0047] LCDs control the color of each pixel using liquid crystals. Since they are difficult to emit light themselves, they receive light through a backlight unit. The backlight unit is a device that evenly supplies light from a light source to the liquid crystals located on the front. The backlight unit can be gradually thinned to achieve a thin LCD.

[0048] If LED or OLED is used, since each element constituting a pixel emits its own light, there is no need to use a backlight unit, thus enabling bending. In addition, since each element emits its own light, its brightness is not affected even if its positional relationship with adjacent elements changes, so LED or OLED can be used to realize a flexible display panel 110.

[0049] LED (Light Emitting Diode) panels utilize a single LED element as a pixel, reducing the size of LED elements compared to existing technologies. This allows for increased resolution and the creation of flexible display panels. Due to their high brightness, LEDs are clearly visible even in bright sunlight, making them suitable for outdoor billboards. Compared to other display technologies, they consume less power and have a longer lifespan, resulting in lower maintenance costs. The use of RGB LEDs provides excellent color performance and more realistic images.

[0050] OLED (Organic Light Emitting Diodes) panels officially debuted in mid-2010 and quickly replaced LCDs in the small and medium-sized display market. As a display that utilizes the self-emissive phenomenon of light emission when an electric current flows through fluorescent organic compounds, OLED displays have a faster image response time than LCDs, resulting in almost no ghosting when displaying videos.

[0051] OLEDs use three phosphor organic compounds that have self-luminous properties: red, green, and blue. They are luminescent display products that utilize the phenomenon of electrons injected from the cathode and anode and positively charged particles combining within the organic material to emit light. Therefore, there is no need for backlighting (backlight device) to reduce color sensitivity.

[0052] Figure 2 This is an exploded rear perspective view of a display device 100 according to an embodiment of the present invention. The display device of the present invention may include a display panel 110 and a module cover 120 located on the back of the panel 110, electronic components disposed on the back of the module cover 120, and a rear cover covering the electronic components and forming the rear appearance of the display device 100.

[0053] A plurality of panel substrates 118 controlling the driving of each pixel of the display panel 110 may be located at the lower rear end of the display panel 110. The panel substrates 118 may be located on the front of the module cover 120 and may penetrate the module cover 120 to connect with the main board located on the back of the module cover 120.

[0054] The module cover 120 may include a metallic material to achieve rigidity and heat dissipation. It may include a bead that protrudes rearward by pressing a metal plate. The bead enhances the rigidity of the module cover 120 and provides space for a plurality of electronic components fastened to the back of the module cover 120 and for fasteners fastened to the rear cover.

[0055] The electronic components mounted on the back of the module cover 120 may include multiple printed circuit boards 180, speakers 160, sensors such as IR sensors or illuminance sensors, antennas such as Wireless Fidelity (WiFi) / Bluetooth, buttons for user input or external input, and input terminals.

[0056] The printed circuit board 180 may include a main board (mother board), a timing control board (T-Con board), a power supply board, etc.

[0057] The motherboard (Main Board / Mother Board) is the core circuit, responsible for image processing, audio processing, input signal processing, etc., and contains the CPU, memory, HDMI / USB input ports, tuner, etc.

[0058] The power supply board converts alternating current (AC) to direct current (DC) and supplies the required voltage to each printed circuit board 180. It also contains transformers, capacitors, rectifiers, etc.

[0059] The T-Con board (Timing Control Board) controls the signals between the mainboard and the display panel 110. It can precisely adjust the image signals to aid in the display of the image, and can control the scanning sequence, resolution, etc.

[0060] In addition, a sub-board may be included to control components such as IR sensors, WiFi / Bluetooth, and buttons that are arranged separately from the motherboard.

[0061] A plurality of printed circuit boards 180 can be connected by cables, and each printed circuit board 180 includes a driver chip 182. The driver chip 182 is an integrated circuit of electronic components with resistors, transistors and capacitors mounted on a small semiconductor, and may include at least one of a system on chip (SoC), a power management IC (PMIC), a memory chip (DDR), and an audio chip.

[0062] Figure 3 This is a rear view of a printed circuit board 180 of a display device 100 according to an embodiment of the present invention. In the printed circuit board 180, the side without the driver chip 182 can be arranged to face the back of the module cover 120, and the side with the driver chip 182 can be arranged to face the rear of the electronic device 100.

[0063] Because the driver chip 182 generates heat due to its concentrated functionality within a limited space, it is essential to dissipate this heat quickly to prevent a decline in its functionality. Since the module cover 120 is made of metal, it effectively dissipates heat.

[0064] As described above, the printed circuit board 180 may include a plurality of them, and in order to secure them to the module cover 120, screws or the like are used for fastening. However, since the process of placing the printed circuit board 180 on the module cover 120 and the process of fastening the screws are performed separately, the number of processes increases.

[0065] Furthermore, the manual nature of the screw-fastening process presents challenges for automation. Additionally, to ensure sufficient tightening force, the screws require a thickness exceeding a specified level, thus increasing the thickness of the electronic device 100.

[0066] Therefore, in this invention, after the printed circuit board 180 is placed on the back side of the module cover 120 by using the transfer gripper of a robotic arm, a board holder 121 protruding towards the back side can be formed on the module cover 120 (see reference). Figure 7 ( ), to be fixed to the module cover 120, and may include a PCB clip 183 in the printed circuit board 180 that is coupled with the board retainer.

[0067] The board retainer 121 may have a protrusion that is open on one side by cutting a portion of the module cover 120 and pressing it toward the back. The PCB clip 183 located on the printed circuit board 180 may be inserted into the open portion and secured to the board retainer 121 by means of the elasticity of the PCB clip 183.

[0068] After the printed circuit board 180 is placed on the back of the module cover 120 using a transfer gripper 200 connected to a robotic arm and having multiple fingers at its end, the printed circuit board 180 is pressed and secured in a first direction D1. The PCB clamp 183 can open in the first direction D1 that pushes the printed circuit board 180, and the board holder can open in the opposite direction.

[0069] The plurality of PCB clips 183 can be arranged separately along a second direction D2 perpendicular to the first direction D1 so as not to overlap in the first direction D1. If they are arranged parallel to the first direction D1, interference may occur with the protruding board holder when the printed circuit board 180 is fastened along the first direction D1.

[0070] In this embodiment, the board retainers can be arranged in three and form a triangle to prevent the printed circuit board 180 from shaking or tilting on the back of the module cover 120.

[0071] The motherboard in the printed circuit board 180 may have more than just external connectors 186 for connecting to external devices. Multiple external connectors 186 may be arranged and mounted on one side of the printed circuit board, and may include connector brackets 187 facing the sides of the multiple external connectors 186. The connector brackets 187 may be exposed to the rear of the electronic device through openings formed in the rear cover, and may include multiple connector holes 1872 to expose the external connectors 186.

[0072] Electronic devices can connect to various external devices and expand their functionality, thereby increasing the number of external connectors 186. A plurality of external connectors 186 are arranged in a row on one side of the printed circuit board. To accommodate a larger number of external connectors 186, the spacing between the external connectors 186 needs to be narrowed.

[0073] Figure 4 This is a diagram showing a portion of an existing printed circuit board. (See reference...) Figure 4 In the prior art, a structure in which the hook 1871 of the connector bracket 187 is inserted and fixed to the hook hole 1817 formed separately from the printed circuit board is used.

[0074] In this case, there is a problem that the area occupied by the hook hole 1817 is reduced by the reduced mounting area of ​​the printed circuit board. In one embodiment of the present invention, the board 181 does not need to have the separate hook hole 1817 as described above, and the connector bracket 187 can be fixed by the joint portion 1832 of the PCB clip 183 described later.

[0075] Figure 5 This is a perspective view showing a PCB clip 183 according to an embodiment of the present invention. (Refer to...) Figure 5 The PCB clamp 183 may include a retaining plate 1831, a connecting part 1832, a fixing part 1833, an elastic clamp 1835, a first connecting part 1837, and a second connecting part 1839.

[0076] The retaining plate 1831 may cover at least a portion of the clamping hole 1813 of the plate 181 and is located on the first side of the plate 181. A connecting portion 1832 may be formed on the retaining plate 1831. The connecting portion 1832 may include one of a square hole, a circular hole, or a groove shape open on one side, and a suitable shape may be selected according to the shape of the component connected to the connecting portion 1832 and the connection method.

[0077] For example, in Figures 5 to 7 In the embodiment shown, the joint 1832 may be in the shape of a groove open on one side, as described later. Figure 10 In the embodiment shown, the joint 1832 may be in the shape of a square hole, as described later. Figure 11In the embodiment shown, the joint 1832 may be in the shape of a circular hole.

[0078] The fixing portion 1833 can be connected to the periphery of the retaining plate 1831 and fastened to at least a portion of the periphery of the clamping hole 1813. According to one embodiment, the fixing portions 1833 can be located on opposite sides of the periphery of the clamping hole 1813. As described above, the fixing portions 1833 can be located only in a portion of the periphery of the clamping hole 1813, so that the remaining periphery of the clamping hole 1813 can be open.

[0079] The elastic clip 1835 can be connected to at least one of the retaining plate 1831 or the fixing part 1833, and can extend through the clamp hole 1813 and protrude toward the second surface of the plate 181. (Refer to...) Figure 9 The elastic clip 1835 can hold a plurality of elastic legs 1835a, 1835b arranged separately from each other, thereby elastically deforming and providing a fastening force when inserted into the plate holder 121 of the module cover 120.

[0080] The PCB clip 183 may include a first connecting portion 1837 connecting the retaining plate 1831 and the elastic clip 1835. According to an embodiment, instead of or additionally included, the PCB clip 183 may also include a second connecting portion 1839 connecting the fixing portion 1833 and the elastic clip 1835. That is, the elastic clip 1835 can be connected to the retaining plate 1831 via the first connecting portion 1837 or to the fixing portion 1833 via the second connecting portion 1839, or both can be connected via the first connecting portion 1837 and the second connecting portion 1839.

[0081] Figure 5 and Figure 6 The illustration shows an embodiment in which the retaining plate 1831 and the elastic clip 1835 are connected by the first connecting part 1837. However, the structure of the second connecting part 1839, which directly connects the fixing part 1833 and the elastic clip 1835, corresponds to the connection method used in the prior art. It can be understood as a modified embodiment that can be easily implemented by a person skilled in the art even without a separate illustration.

[0082] Figure 6 This is a perspective view, viewed from the second side, showing the PCB clamp 183 of a printed circuit board 180 according to an embodiment of the present invention engaged with the clamp hole 1813. (Refer to...) Figure 6 It can be confirmed that the elastic clip 1835 can pass through the clamp hole 1813 and protrude to the second side of the plate 181, and the fixing part 1833 and the periphery of the clamp hole 1813 are fastened to the edge of the clamp hole 1813 on both sides facing each other.

[0083] Figures 7 to 9This is a perspective view showing the form in which a printed circuit board 180 and a module cover 120 are fastened according to an embodiment of the present invention. If the printed circuit board 180 is placed on the back of the module cover 120, the elastic clip 1835 of the PCB clip 183 engages with the board holder 121 of the module cover 120 on the third direction DR3.

[0084] Subsequently, if the printed circuit board 180 is slidably moved along the first direction D1 in the surface direction by using the transfer gripper 200 of the robotic arm, the elastic clip 1835 can slide along the open portion of the board holder 121 and be locked in place on the board holder 121. As described above, the elastic clip 1835 can slide along the surface direction after engaging with the module cover 120 in the vertical direction, and the printed circuit board 180 can be firmly fixed to the module cover 120 by a fastening structure without the need for separate fastening components such as screws.

[0086] Reference Figure 10 The printed circuit board 180 may include a plurality of external connectors 186 mounted on one side of the board 181 and a connector bracket 187 fastened to one side of the board 181. The connector bracket 187 may include a plurality of connector holes 1872 formed at positions corresponding to the plurality of external connectors 186 and bracket hooks 1871 protruding toward the board 181 and engaging with the joint portion 1832.

[0087] exist Figure 10 In the embodiment shown, the connecting portion 1832 may be in the shape of a square hole, and the bracket hook 1871 may be inserted into the square hole-shaped connecting portion 1832 and locked in place. A plurality of external connectors 186 may be inserted into a plurality of connector holes 1872 of the connector bracket 187, so that the plurality of external connectors 186 can be arranged in the correct position. The PCB clip 183 may be arranged adjacent to the connector bracket 187.

[0088] Figure 11 (a) is a diagram showing a heat sink 185 of the joint portion 1832 of the PCB clip 183 incorporated in an embodiment of the present invention.

[0089] Reference Figure 11 (a) The printed circuit board 180 may include a heat sink 185 covering at least a portion of a first side of the plate 181 and a heat sink fastener 1854 penetrating the heat sink 185 and coupled to the joint 1832.

[0090] The heat sink 185 can perform the function of releasing the heat generated in the heat-generating components such as the driver chip 182. The heat sink fastener 1854 can be combined with the joint 1832, so that no separate fastening structure is needed. The heat sink 185 can also be fixed to the plate 181.

[0091] exist Figure 11 In the embodiment shown in (a), the joint 1832 may be in the shape of a circular hole, and the heat sink fastener 1854 may be inserted into and fixed to the circular hole-shaped joint 1832.

[0092] Figure 11 Figure (b) is a diagram showing the fastening hook 188 of the rear cover 130 of the PCB clip 183 incorporating the coupling portion 1832 according to an embodiment of the present invention. (Refer to...) Figure 11 (b) The electronic device 100 may include a rear cover 130 that covers a first side of the printed circuit board 180 and is fastened to the module cover 120. The printed circuit board 180 may include a fastening hook 188 that is fastened to a coupling portion 1832 and engages with a rear cover hole 131 of the rear cover 130. If the rear cover 130 covers the first side of the printed circuit board 180, the fastening hook 188 may be inserted into and engaged with the rear cover hole 131, thereby securing the rear cover 130 to the printed circuit board 180 and the module cover 120.

[0093] The connector bracket 187, heat sink 185 and fastening hook 188 of the rear cover 130 described above are just examples of dissimilar parts that can be attached to the joint 1832. Any part that has a fastening structure corresponding to the shape of the joint 1832 can be attached to the joint 1832, regardless of its type.

[0094] According to the present invention, the PCB clamp can simultaneously perform the function of fixing the printed circuit board to the module cover and the function of combining dissimilar components such as connector brackets, heat sinks or back covers. Therefore, it is not necessary to form separate fastening holes on the printed circuit board for fixing dissimilar components, thereby ensuring the mounting area of ​​the printed circuit board and achieving miniaturization.

[0095] In addition, since the PCB clamp's elastic clamp slides and tightens after it aligns with the module cover in the vertical direction, there is no need for separate fastening components such as screws. The printed circuit board can be automatically assembled onto the module cover using robots, thereby simplifying the assembly process and improving production efficiency.

[0096] In addition, the use of a PCB clip can be used to fix printed circuit boards and dissimilar components, thereby reducing the number of components and assembly time, and also helping to make electronic devices thinner.

[0097] The detailed description above should not be construed as restrictive in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention are included within the scope of the invention.
