FIG.3is a view illustrating a coupling relationship between a printed circuit board and a case of the electronic device according to some embodiments of the present disclosure.FIGS.4and5are views illustrating a process of coupling the printed circuit board ofFIG.3to the case.

Referring toFIGS.3to5, the electronic device1may include the printed circuit board50on which electronic components P are mounted. The printed circuit board50is formed by printing a circuit line pattern with a conductive material such as copper on an electrical insulating board, and may refer to a board on which electronic components are mountable.

The main board may include a processor and a power management unit for driving the electronic device1. The SMPS board may supply power to drive the electronic device1. When the electronic device1is a display apparatus, the source board may control the display panel10.

The main board, the SMPS board, and the source board may be disposed independently of each other or merged with each other. The circuit boards arranged independently of each other may be connected to each other to exchange data, signals, or power.

As illustrated inFIG.2, a plurality of printed circuit boards50may be provided in a single electronic device1. However, the number of printed circuit boards50provided in the electronic device1is not limited to that shown inFIG.2. Alternatively, a single printed circuit board50may be provided in a single electronic device1.

The electronic device1may include the case40on which the printed circuit board50is mounted. The printed circuit board50may be mounted on the case40by a mounting member100.

The case40may include a board mounting portion200on which the printed circuit board50is mounted. The board mounting portion200may be provided to face one surface of the printed circuit board50in the case40. The board mounting portion200may be disposed on one surface of the case40facing the printed circuit board50.

The board mounting portion200may have a shape that protrudes toward the printed circuit board50. Particularly, the case40may include a board separation surface40aformed to face one surface, which is on the side of the board mounting portion200, of the printed circuit board50when the printed circuit board50is seated in the case40. Further, the board mounting portion200may have a shape that protrudes from the board separation surface40a. For example, as shown inFIG.2, the board separation surface40amay be provided at the rear surface of the bottom chassis40and may face the printed circuit board50disposed at the rear side of the bottom chassis40. The board mounting portion200may be formed to protrude rearward from the bottom chassis40. However, the arrangement of the board mounting portion200and the printed circuit board50is not limited thereto.

Because the board mounting portion200has a shape that protrudes from the board separation surface40a, the printed circuit board50may be mounted on the case40while being spaced apart from the board separation surface40a.

The case40may be formed to include a flat plate shape. Particularly, the board separation surface40afacing the printed circuit board50of the case40may be formed to have a flat plate shape. However, the present disclosure is not limited thereto, and the board separation surface40aand the case40including the same may be formed to include various shapes on which the printed circuit board50is mountable.

The board separation surface40aand the board mounting portion200may be formed integrally with each other. Particularly, the board mounting portion200may be manufactured by pressing a portion of the flat plate-shaped case40. However, the present disclosure is not limited thereto, and the board mounting portion200may be formed in various ways. Alternatively, the board separation surface40aand the board mounting portion200may be manufactured separately and then coupled to each other.

The board mounting portion200may include a seating surface210on which the printed circuit board50is seated. The seating surface210may be formed in parallel with the printed circuit board50and may be arranged to face a board through-hole51(refer toFIG.6) formed in the printed circuit board50. The seating surface210may be formed at one end of the board mounting portion200with respect to a direction of protruding from the board separation surface40a.

The seating surface210may be provided on the other side opposite to one side of an interference wall240(refer toFIG.11) that interferes with an interference portion130(refer toFIG.6), which will be described later.

The board mounting portion200may include an inclined surface220connecting the seating surface210and the board separation surface40a. The inclined surface220may have an inclination formed to allow an area of a cross-section, which is cut in a direction parallel to the board separation surface40a, of the board mounting portion200to be reduced from the board separation surface40atoward the seating surface210. That is, the board mounting portion200may be formed to have the overall shape of a horn.

The board mounting portion200may include an insertion hole230formed to allow at least a portion of the mounting member100, which is coupled to the printed circuit board50, to be inserted thereinto. The board mounting portion200may include a cavity formed inside the insertion hole230to accommodate at least a portion of the mounting member100inserted through the insertion hole230. In other words, the board mounting portion200may include a concave space formed on a side opposite to the side on which the printed circuit board50is mounted, and at least a portion of the mounting member100may be inserted through the insertion hole230and accommodated in the concave space of the board mounting portion200.

The insertion hole230may be formed to allow the interference portion130(refer toFIG.6), which will be described later, to be inserted thereinto, and thus the printed circuit board50may be mounted on the board mounting portion200in a sliding manner by using the mounting member100.

The insertion hole230may be formed to be open in a direction parallel to the direction in which the printed circuit board50extends. That is, the insertion hole230may be formed to allow the printed circuit board50to be inserted in a direction M2 parallel to the direction in which the printed circuit board50extends. In this case, the insertion hole230may be provided on the inclined surface220. However, the present disclosure is not limited thereto, and the printed circuit board50may be mounted on the case40in various directions, and the insertion hole230may also be formed to correspond to the direction M2 through which the interference portion130of the mounting member100is inserted. For example, the printed circuit board50may be inserted in a direction M1 parallel to the direction in which the printed circuit board50and the board separation surface40aface, and in this case, the insertion hole230may be formed in the direction M1 from the seating surface210.

When the insertion hole230is provided in plurality because the board mounting portion200is provided in plurality or when the plurality of insertion holes230is formed in a single board mounting portion200, the plurality of insertion holes230may be formed to be open in a constant direction. That is, the plurality of insertion holes230may be formed to allow the direction, in which the interference portion130of the plurality of mounting members100is inserted, to be constant. Accordingly, the interference portion130may be easily mounted in the insertion hole230or easily removed from the insertion hole230. However, the present disclosure is not limited thereto, and the insertion hole230may be formed in various ways, and a single insertion hole230may be formed.

However, the shape of the board mounting portion200is not limited thereto, and may include various shapes in which the printed circuit board50is mountable by the mounting member100. For example, the mounting member100coupled to the printed circuit board50may include a hole or a groove, and the board mounting portion200may include a protrusion provided to penetrate the hole or to be inserted into the groove of the mounting member100. Accordingly, the printed circuit board50may be mounted on the board mounting portion200in a method in which the protrusion of the board mounting portion200interferes with the hole or the groove of the mounting member100.

The board mounting portion200may be provided in plurality, as shown inFIGS.3to5. However, the present disclosure is not limited thereto and the board mounting portion200may be provided in various numbers to allow the printed circuit board50to be stably mounted on the case40. A single board mounting portion200may be provided.

With the above configuration, the printed circuit board50may move in the direction M1 from the position ofFIG.3toward the case40as shown inFIG.4, and then, as the printed circuit board50moves in the direction M2, the interference portion130(refer toFIG.6) of the mounting member100coupled to the printed circuit board50may be inserted into the insertion hole230in the direction M2 and mounted on the board mounting portion200. However, the method in which the printed circuit board50is mounted on the board mounting portion200by the mounting member100is not limited thereto.

The interference portion130, which will be described later, may be provided to interfere with the interference wall240(refer toFIG.11) of the board mounting portion200so as to allow the printed circuit board50to be mounted on the board mounting portion200. Accordingly, the printed circuit board50may be removably mounted on the board mounting portion200. For example, the interference portion130may be provided to be removable after being inserted into the board mounting portion200through the insertion hole230, and thus the printed circuit board50may be removably mounted on the board mounting portion200. However, the present disclosure is not limited thereto, and the printed circuit board50may be mounted to the board mounting portion200in a non-removable manner. Even when the electronic device1includes all of the above-described configurations, the printed circuit board50may be fixed to the board mounting portion200by a separate fixing member, and thus the printed circuit board50may be not removable from the board mounting portion200.

The case40may include a board guide portion201provided to guide the movement of the printed circuit board50, in addition to the board mounting portion200. The board guide portion201may be formed to have a shape that protrudes from the board separation surface40a. The board guide portion201may include a guide protrusion201ahaving a protruding shape, and the printed circuit board50may be provided with a guide hole54aformed in a position corresponding to a position of the guide protrusion201awhen the printed circuit board50is mounted on the case40. The guide protrusion201amay be inserted into the guide hole54a.

The guide hole54amay extend in the direction in which the printed circuit board50is mounted on the board mounting portion200. For example, as shown inFIG.5, the guide hole54amay extend in a direction parallel to the direction M2 corresponding to a direction in which the printed circuit board50is mounted to the board mounting portion200, that is, the direction in which the interference portion130is inserted into the insertion hole230. The printed circuit board50may be guided to move in the direction, in which the printed circuit board50is mounted on the case40, by the guide protrusion201ainserted into the guide hole54a. Further, even when the printed circuit board50is separated from the case40, the printed circuit board50may be guided to move in a direction, in which the printed circuit board50is separated from the case40, by the guide protrusion201a.

As illustrated inFIGS.3to5, the case40may include the board mounting portion202, in which the insertion hole230provided to allow the interference portion130of the mounting member100to be inserted and the guide protrusion201aprovided to guide the movement of the printed circuit board50are provided. The guide protrusion201amay be provided on the seating surface210.

The guide protrusion201aof the board mounting portion202may have a protruding shape to be inserted into the guide hole54bformed in the printed circuit board50. The guide protrusion201amay be inserted into the guide hole54bto guide the movement of the printed circuit board50to allow the printed circuit board50to be mounted on or to be separated from the case40.

A stopper201bformed in a protruding shape may be provided on the seating surface210of the board mounting portion202to prevent the printed circuit board50from being easily separated after being mounted at a predetermined position on the case40.

The stopper201bmay be formed to protrude from the seating surface210of the board mounting portion202, like the guide protrusion201a, and may be formed to be inserted into the guide hole54bof the printed circuit board50. The stopper201bmay be inserted into the guide hole54bto support one side of the guide hole54b, and thus the printed circuit board50may be stably mounted on the case40.

With the above configuration, the electronic device1may easily mount the printed circuit board50, to which the mounting member100is coupled, to the case40by sliding the printed circuit board50against the board mounting portion200of the case40. At this time, manufacturing time and manufacturing cost may be reduced in comparison with a method in which the printed circuit board50is directly fastened to the case40, such as by fastening screws. In addition, even when it is required to separate the printed circuit board50from the case40for repair or replacement of the electronic component (p), the printed circuit board50coupled to the case40in the sliding manner may be more easily separated in comparison with the printed circuit board50coupled to the case40by the fastening screws.

However, the present disclosure is not limited thereto, and the case40may be configured to include various structures for mounting the printed circuit board50to the case40. UnlikeFIGS.3to5, the case40may not be provided with the board guide portion201, and the case40may not be provided with the board mounting portion202including the guide protrusion202aand the stopper202b.

Hereinafter for convenience of description, the board mounting portion200excluding the guide protrusion202aand the stopper202bwill be described as an example. However, the following configurations may also be applied to the board mounting portion200including the guide protrusion202aand the stopper202b.

As the support portion111is inserted into the support hole52, the mounting member100may be more stably supported on the printed circuit board50.

In other words, the bracket body110may include the support portion111provided to be inserted into and supported in the support hole52, and the mounting bracket100may be more stably supported on the printed circuit board50.

However, the present disclosure is not limited thereto, and the mounting body110may have various shapes.FIGS.6and7illustrate that the support portion111is formed at an end of the mounting body110. However, the support portion111may be formed at another position of the mounting body110. At this time, according to the position of the support portion111, the support portion111may be inserted into another configuration of the printed circuit board50other than the support hole52, for example, the board through-hole51. Alternatively, the mounting body110may not include the support portion111.

The mounting member100may include a fixing portion120provided to couple the mounting member100to the printed circuit board. The fixing portion120may extend from the mounting body110and be provided to fix the mounting member100to the printed circuit board50.

The fixing portion120may extend from the mounting body110so as to penetrate the printed circuit board50or at least be inserted into the printed circuit board50when the mounting member100is coupled to the printed circuit board50. When the mounting body110is seated on one surface of the printed circuit board50opposite to the board mounting portion200, the fixing portion120may extend from the mounting body110toward the board mounting portion200.

The fixing portion120may be provided in plurality. The plurality of fixing portions may be formed to be symmetrical to each other. In this case, the mounting member100may be more stably fixed to the printed circuit board50. However, the present disclosure is not limited thereto, and a single fixing portion120may be provided.

At least a portion of the fixing portion120may be formed to penetrate a fixing hole53formed in the printed circuit board50. The at least a portion of the fixing portion120penetrating the fixing hole53may be fixed to the printed circuit board50through soldering fixation F as shown inFIG.7. However, the present disclosure is not limited thereto, and the fixing portion120may be fixed to the printed circuit board50in various ways.

At least a portion of the fixing portion120may extend toward the board through-hole51and may be supported on an inner surface of the board through-hole51. However, the present disclosure is not limited thereto, and all of the fixing portions120may be supported on the printed circuit board50by passing through the fixing holes53.

The fixing portion120may be referred to as a fixing pin120. In other words, the mounting bracket100may include the fixing pin120provided to extend from the bracket body110and fixed to the printed circuit board50. Accordingly, the mounting bracket100may be fixed to the printed circuit board50. At least a portion of the fixing pin120may be formed to penetrate the fixing hole53and fixed to the printed circuit board50through the soldering fixation F.

That is, in a method of inserting the fixing portion120into the fixing hole53of the printed circuit board50and then fixing the fixing portion120to the printed circuit board50through the soldering fixation F, the mounting member100may be easily fixed to the printed circuit board50, and the mounting member100may be stably coupled to the printed circuit board50. In other words, in a method of inserting the fixing portion120into the fixing hole53of the printed circuit board50and then fixing the fixing portion120to the printed circuit board50through the soldering fixation F, the mounting bracket100may be easily fixed to the printed circuit board50, and the mounting bracket100may be stably coupled to the printed circuit board50.

The mounting member100may include the interference portion130provided to interfere with the board mounting portion200. A configuration of the board mounting portion200provided to interfere with the interference portion130of the mounting member100may be referred to as the interference wall240(refer toFIG.11).

In other words, the mounting bracket100may include the interference portion130provided to interfere with the interference wall240to couple the mounting bracket100to the case40. The interference of the interference portion130with the interference wall240will be described later.

The interference portion130may extend from the mounting body110. Particularly, the interference portion130may extend from the mounting body110toward the board mounting portion200. In other words, the interference portion130may extend from the bracket body110toward the board mounting portion200.

When the mounting body110is seated on one surface of the printed circuit board50opposite to the board mounting portion200, the interference portion130may extend from the mounting body110to penetrate the printed circuit board50. In other words, the interference portion130may extend from the bracket body110to penetrate the printed circuit board50. At this time, the board through-hole51may be formed in the printed circuit board50, and the interference portion130may penetrate the board through-hole51.

In other words, the interference portion130may be disposed on one side of the printed circuit board50facing the board mounting portion200, and the mounting body110may be disposed on the other side of the printed circuit board50. In this case, the mounting member100may mount the printed circuit board50to the board mounting portion200so as to be in closer contact with the board mounting portion200. Accordingly, a bonding force between the printed circuit board50and the board mounting portion200may be improved, and a gap between the printed circuit board50and the board mounting portion200may be reduced to achieve miniaturization of the electronic device1. However, the present disclosure is not limited thereto, and when the mounting body110is seated on one surface of the printed circuit board50facing the board mounting portion200, the interference portion130may not penetrate the printed circuit board50.

The interference portion130may include extension portions132and133provided to interfere with the interference wall240and a connection portion131connecting the extension portions132and133and the mounting body110. The connection portion131may extend from the mounting body110, and the extension portions132and133may extend from the connection portion131. The connection portion131may be provided to penetrate the board through-hole51.

The extension portions132and133may be formed to be bent and extend from one end of the connection portion131. The extension portions132and133may include a first extension portion132extending from one end of the connection portion131toward the mounting body110, and a second extension portion133provided to be bent and extend from one end, which is opposite to the connection portion131, of the first extension portion132. A bending portion134having a bent shape may be disposed between the first extension portion132and the second extension portion133.

In other words, when the printed circuit board50is mounted on the board mounting portion200by the mounting member100, the interference portion130may include the first extension portion132extending toward the interference wall240(refer toFIG.11), the bending portion134formed to be bent at one end, which faces the interference wall240, of the first extension portion132, and the second extension portion133extending from the bending portion134.

The second extension portion133may extend from the bending portion134to a direction away from the mounting body110. That is, when the printed circuit board50is mounted on the board mounting portion200by the mounting member100, the second extension portion133may extend from the bending portion134to a direction away from the interference wall240. In this case, among the first extension portion132, the second extension portion133, and the bending portion134, the bending portion134may be closest to the mounting body110. In other words, the bending portion134may be provided to be closest to the interference wall240.

However, the above description of the configuration of the mounting member100is only an example of the mounting member100according to the present disclosure, and the configuration of the mounting member100is not limited thereto. The mounting member100may be configured in various ways as long as the mounting member100is fixed to the printed circuit board50so as to mount the printed circuit board50to the board mounting portion200. That is, the mounting member100may have various shapes according to the shape of the board mounting portion200and the method of mounting the printed circuit board50to the board mounting portion200.

For example, the mounting member100coupled to the printed circuit board50may include a hole or a groove, and the board mounting portion200may include a protrusion provided to penetrate the hole or provided to be inserted into the groove of the mounting member100. Accordingly, in a method in which the protrusion of the board mounting portion200interferes with the hole or the groove of the mounting member100, the printed circuit board50may be mounted on the board mounting portion200. In this case, the hole or the groove of the mounting member100may perform the function of the interference portion130, and the protrusion of the board mounting portion200may interfere with the hole or the groove of the mounting member100to perform the function of the interference wall240(refer toFIG.11) described later.

FIG.8is a view illustrating the mounting member of the electronic device according to some embodiments of the present disclosure.FIG.9is a view illustrating the mounting member ofFIG.8when viewed from another direction.FIG.10is an enlarged view of A inFIG.9.FIG.11is a cross-sectional view illustrating before the printed circuit board is mounted on the case in the electronic device according to some embodiments of the present disclosure.FIG.12is a cross-sectional view illustrating after the printed circuit board ofFIG.11is mounted on the case.FIG.13is an enlarged view of B ofFIG.12.FIG.14is a view illustrating the printed circuit board mounted in the case ofFIG.12when viewed from another direction.

Referring toFIGS.8and14, the printed circuit board50, to which the mounting member100is coupled, may be mounted on the board mounting portion200by sliding and moving in the direction M2 as shown inFIGS.4and5. In other words, the printed circuit board50, to which the mounting bracket100is coupled, may be mounted on the board mounting portion200by sliding and moving in the direction M2.

The board mounting portion200may include the insertion hole230, and the mounting member100may include the interference portion130inserted into the insertion hole230. The interference portion130may be inserted into the interference wall240of the board mounting portion200through the insertion hole230. The interference portion130may be inserted into the insertion hole230and then in contact with the interference wall240, and may interfere with the interference wall240to mount the mounting member100and the printed circuit board50to the board mounting portion200. At this time, a scratch protrusion140, which will be described later, may also be inserted through the insertion hole230together with the interference portion130, and the scratch protrusion140may be in contact with the interference wall240.

The interference wall240may be formed parallel to the mounting body110. Further, the interference wall240may be formed parallel to the printed circuit board50. In this case, the interference portion130may interfere with the interference wall240while moving in the direction M2 parallel to the mounting body110and the printed circuit board50. The printed circuit board50may be mounted on the board mounting portion200while sliding and moving in the direction M2. At this time, the scratch protrusion140, which will be described later, may be also inserted into the insertion hole230in the direction M2 parallel to the direction, in which the printed circuit board50extends, and may be in contact with the interference wall240.

The interference portion130may be provided in such a way that a distance between the bending portion134and the mounting body110when the interference portion130does not interfere with the interference wall240is less than a distance between the bending portion134and the mounting body110when the interference portion130interferes with the interference wall240. In other words, as shown inFIGS.11and12, the interference portion130may be provided in such a way that a gap between the connection portion131and the first extension portion132is increased when the interference portion130interferes with the interference wall240. In other words, an angle a2 between the connection portion131and the first extension portion132when the interference portion130interferes with the interference wall240may be greater than an angle a1 between the connection portion131and the first extension portion132when the interference portion130does not interfere with the interference wall240. Accordingly, when the interference portion130interferes with the interference wall240, the bending portion134may press the interference wall240, and the printed circuit board50may be stably mounted on the board mounting portion200.

As described later, the scratch protrusion140may be formed to protrude from the bending portion134toward the interference wall240. At this time, a distance between the scratch protrusion140and the mounting body110when the interference portion130does not interfere with the interference wall240may be less than a distance between the scratch protrusion140and the mounting body110when the interference portion130interferes with the interference wall240.

The interference portion130may be formed to include an elastic material. For example, the interference portion130may be formed to include an elastic metal material. Accordingly, the interference portion130may be elastically deformed and easily interfere with the interference wall240.

As described above, the interference portion130may include the first extension portion132extending toward the interference wall240, the bending portion134being bent at one end, which faces the interference wall240, of the first extension portion132, and the second extension portion133extending from the bending portion134. The second extension portion133may extend from the bending portion134to a direction away from the interference wall240.

Accordingly, even when the mounting body110is not in sufficiently close contact with the printed circuit board50or the printed circuit board50is not in sufficiently close contact with the seating surface210, the second extension portion133may serve as a guide to allow the interference portion130to be easily inserted into the insertion hole230. However, the present disclosure is not limited thereto, and the interference portion130and the second extension portion133of the interference portion130may have various shapes. For example, the second extension portion133may be bent and extend from the first extension portion132, and may also extend in a direction parallel to the interference wall240.

The interference wall240may include a conductive layer240aformed to include a conductive material and coating layers240band240capplied to an outer surface of the interference wall240.

The conductive material included in the conductive layer240amay include a conductive metal material such as iron (Fe). The coating layers240band240cmay be applied to the outside of the conductive layer240ato prevent the corrosion of the conductive layer240a.

The coating layers240band240cmay include a plurality of coating layers240band240cas shown inFIG.13, and particularly, include a first coating layer240band a second coating layer240capplied to the outside of the first coating layer240b.

The first coating layer240band the second coating layer240cmay include various materials provided to prevent the corrosion of the conductive layer240a. For example, the first coating layer240bmay be a zinc (Zn) plating layer, and the second coating layer240cmay be a layer for anti-fingerprint coating, for example, an acrylate coating layer.

However, the present disclosure is not limited thereto, and the type of material forming the coating layers240band240cis not limited thereto. The coating layers240band240cdo not necessarily have to function to prevent the corrosion of the conductive layer240a, and may be applied to the outer surface of the interference wall240for various purposes. In addition, the coating layers240band240cdo not necessarily have to be provided as a plurality of distinct layers, and the first coating layer240band the second coating layer240bmay be a single layer of the same type as a whole.

When the electronic device1performs the function, electromagnetic waves may be generated from the electronic device1, and the electromagnetic waves may be radiated to other surrounding devices and act as noise that affects the operation of surrounding devices. In other words, it may cause electromagnetic interference (EMI). Further, the electromagnetic waves may affect the human body, and thus there are international regulations to prevent the damage.

Particularly, as shown inFIG.2, the electronic device1may include the plurality of printed circuit boards50mounted on the case40, and it may be required that the plurality of printed circuit boards50form a common ground through the case, to reduce the noise caused by electromagnetic waves. Therefore, it is important to improve an extent to which the printed circuit board50is grounded through the case40.

In order to allow the printed circuit board50to be grounded to the case40, the board mounting portion200and the mounting member100may be provided to include a conductive material. Further, the case40may be integrally formed including the board mounting portion200, and the case40may be provided to include a conductive material as a whole. The conductive materials that may be included in the board mounting portion200or the mounting member100may include conductive metal materials such as iron (Fe). Accordingly, the printed circuit board50may be grounded to the board mounting portion200through the mounting member100. In other words, the board mounting portion200and the mounting bracket100may be provided to include a conductive material, and the printed circuit board50may be grounded to the board mounting portion200through the mounting bracket100.

However, when the printed circuit board50is mounted on the board mounting portion200, the interference portion130may not be sufficiently in contact with the interference wall240, and accordingly, the printed circuit board50may not be sufficiently grounded to the case40. Further, the extent to which the interference portion130is in contact with the interference wall240may not be uniform, and thus a deviation may occur in the extent to which the printed circuit board50is grounded to the case40.

Further, as described above, the interference wall240may include the coating layers240band240capplied to the outer surface thereof, and the coating layers240band240cmay be provided to include a non-conductive material. Therefore, even when the interference portion130of the mounting member100is in contact with the interference wall240, the printed circuit board50may not be sufficiently grounded to the case40due to the coating layers240band240c.

To relieve the difficulty, the mounting member100may include the scratch protrusion140protruding from the interference portion130. In other words, the mounting bracket100may include the scratch protrusion140protruding from the interference portion130.

The scratch protrusion140may be formed to protrude from the interference portion130toward the interference wall240when the printed circuit board50is mounted on the board mounting portion200. The scratch protrusion140may be provided to be in contact with the interference wall240and may be provided to scratch the outer surface of the interference wall240when the interference portion130interferes with the interference wall240.

Particularly, when the interference portion130moves in the direction M2 and is inserted into the insertion hole230, the scratch protrusion140may also move along with the interference portion130in the direction M2 and be inserted into the insertion hole230. When the interference portion130interferes with the interference wall240, the scratch protrusion140may also interfere with the interference wall240. In other words, the interference portion130may slide in a direction parallel to the direction, in which the printed circuit board50extends, and interfere with the interference wall240to allow the printed circuit board50to be mounted on the case40. At this time, the scratch protrusion140may also slide relative to the interference wall240in the same direction.

The scratch protrusion140may penetrate the coating layers240band240cwhen the interference portion130interferes with the interference wall240. At this time, the scratch protrusion140may penetrate the coating layers240band240cand be in contact with an inner side of the coating layers240band240cof the interference wall240. That is, the scratch protrusion140may penetrate the coating layers240band240cand be in contact with the conductive layer240a.

At least a portion of the coating layers240band240cmay be removed by the scratch protrusion140when the interference portion130interferes with the interference wall240. In other words, when the scratch protrusion140slides and moves with respect to the interference wall240, at least a portion of the coating layers240band240cmay be removed, and a scratch S through which the conductive layer240ais exposed to the outside may be formed on the outer surface of the interference wall240. The scratch S may be formed along a direction in which the scratch protrusion140moves on the interference wall240.

With this configuration, the coating layers240band240cof the interference wall240may be removed by the scratch protrusion140, and the extent, to which the printed circuit board50is grounded to the board mounting portion200through the mounting member100, may be increased. Further, the extent to which the mounting member100is coupled to the interference wall240may be improved by the scratch protrusion140. In other words, because the mounting bracket100includes the scratch protrusion140, the extent to which the mounting bracket100is coupled to the interference wall240, and the extent to which the printed circuit board50is grounded to the board mounting portion200may be improved.

In addition, the scratch protrusion140may form the scratch S by selectively removing the coating layers240band240cfrom a portion, which is in contact with the scratch protrusion140, on one surface of the interference wall240that interferes with the interference portion130and the scratch protrusion140. Accordingly, the remaining coating layers240band240cthat are not removed may prevent the conductive layer240afrom being damaged by the corrosion or the like.

Hereinafter the shape of the scratch protrusion140will be described in more detail.

The scratch protrusion140may be formed to protrude from the interference portion130so as to be contact with the interference wall240. Particularly, the scratch protrusion140may be disposed between the first extension portion132and the second extension portion133. In other words, the scratch protrusion140may be disposed on the bending portion134and may be formed to protrude from the bending portion134toward the interference wall240. However, the present disclosure is not limited thereto, and the scratch protrusion140may be formed in various ways as long as the scratch protrusion140protrudes from the interference portion130and be in contact with the interference wall240.

The interference portion130may include a through-hole135formed to face the interference wall240. The through-hole135may be formed in the bending portion134. At this time, the scratch protrusion140may be formed in a circumference of the through-hole135. Particularly, the scratch protrusion140may be formed along the circumference of the through-hole135and may have a shape in which an inner side is penetrated along a direction of protruding from the interference portion130. In other words, the scratch protrusion140may include a hollow that is penetrated in a direction facing the interference wall240. The hollow of the scratch protrusion140may extend from the through-hole135toward the interference wall240. In other words, the scratch protrusion140may be formed to include a shape similar to a hollow cylinder shape.

An inner surface of the scratch protrusion140may be formed integrally with an outer circumference of the through-hole135. That is, the scratch protrusion140may be formed along the outer circumference of the through-hole135, and the inner surface of the scratch protrusion140may be formed to protrude from the outer circumference of the through-hole135toward the interference wall240.

Further, the scratch protrusion140may be formed integrally with the interference portion130. However, the present disclosure is not limited thereto, and the scratch protrusion140may be formed separately from the interference portion130and then coupled to the interference portion130.

When the printed circuit board50is disposed at the rear side of the bottom chassis40as illustrated inFIG.2, the scratch protrusion140may protrude from the front side to the rear side of the bottom chassis40. However, the present disclosure is not limited thereto, and the scratch protrusion140may be formed in various ways according to the arrangement relationship between the printed circuit board50and the bottom chassis40and the method in which the printed circuit board50is mounted on the bottom chassis40.

With the above configuration, because the mounting member100includes the scratch protrusion140provided to scratch the outer wall of the interference wall240when the interference portion130interferes with the interference wall240, the bonding force or contact force between the mounting member100and the interference wall240may be improved, and the extent, to which the printed circuit board50is grounded to the case40, may be improved. In other words, because the mounting bracket100includes the scratch protrusion140provided to scratch the outer wall of the interference wall240when the interference portion130interferes with the interference wall240, the bonding force or contact force between the mounting bracket100and the interference wall240may be improved, and the extent, to which the printed circuit board50is grounded to the case40, may be improved.

However, the configuration of the scratch protrusion140is not limited thereto, and the scratch protrusion140may include various configurations provided to protrude from the interference portion130and provided to scratch the outer surface of the interference wall240of the board mounting portion200.

FIGS.15and16are views briefly illustrating a process of forming a scratch protrusion of the electronic device according to some embodiments of the present disclosure.

Referring toFIGS.15and16, the scratch protrusion140may be manufactured in a method in which a portion of the interference portion130is pressed to be penetrated by using a tool T with a sharp tip. That is, the scratch protrusion140may be manufactured through burring processing.

As illustrated inFIG.15, the tool T for manufacturing the scratch protrusion140may be positioned between the first extension portion132and the second extension portion133. That is, the tool T may be positioned on the bending portion134prior to manufacturing the scratch protrusion140.

The tip of the tool T may be located on one surface of the bending portion134and penetrate the bending portion134while moving in a direction D1 as shown inFIG.16. One surface of the bending portion134may refer to one surface opposite to the interference wall240when the interference portion130interferes with the interference wall240in a direction opposite to the direction in which the scratch protrusion140protrudes from the interference portion130. That is, the direction D1, which is a moving direction of the tool T, may be parallel to a direction in which the scratch protrusion140protrudes from the interference portion130.

When the tool T penetrates the bending portion134while moving in the direction D1, the through-hole135may be formed in the bending portion134. At the same time, at least a portion of the bending portion134may be pressed by the tool T and bent in the direction D1 to protrude. That is, the scratch protrusion140may be formed in such a way that at least a portion of the bending portion134is pressed to form the through-hole135and protrudes by being bent in the direction D1 at the position, in which the through-hole135is formed.

Through this process, the scratch protrusion140may be formed to protrude in the direction D1, in which the interference portion130is pressed, when the through-hole135is formed by the interference portion130. The scratch protrusion140may be formed to protrude in the direction D1 (e.g. a pressing direction of the interference portion130) when through hole is pressed.

However, unlikeFIGS.15and16, the scratch protrusion140may be formed to protrude from a position other than the bending portion134of the interference portion130, and the through-hole135may be formed to protrude from a position in the interference portion130other than the bending portion134. In this case, the tool T may press a position in the interference portion130other than the bending portion134to penetrate the interference portion130and form the scratch protrusion140.

A shape and size of the scratch protrusion140may vary according to the type of tool T, a moving distance of the tool T, and an intensity of pressure of the interference portion130. This is also applied to the through-hole135formed in the interference portion130.

When manufacturing the scratch protrusion140through the above-mentioned method, it is possible to reduce material costs and processing time in comparison with the method in which the scratch protrusion140is manufactured separately and coupled to the interference portion130.

However, the description described inFIGS.15and16is only an example of the method for manufacturing the scratch protrusion140in the mounting member100of the electronic device1according to the present disclosure, and the scratch protrusion140may be manufactured in various methods.

FIG.17is a view illustrating a mounting member of an electronic device according to some embodiments of the present disclosure.FIG.18is a view illustrating the mounting member ofFIG.17when viewed from another direction.

Referring toFIGS.17and18, a mounting member of an electronic device according to some embodiments of the present disclosure will be described. In describing the embodiment shown inFIGS.17and18, the same components as those shown inFIGS.1to16may be assigned the same reference numerals and a description thereof may be omitted.

Referring toFIGS.17and18, a mounting member1000may include a plurality of scratch protrusions140. In other words, the mounting bracket1000may include the plurality of scratch protrusions140.

The plurality of scratch protrusions140may each be formed to protrude from the interference portion130. Particularly, the plurality of scratch protrusions140may be formed to protrude from the bending portion134, respectively. However, the present disclosure is not limited thereto, and the plurality of scratch protrusions140may be formed in various ways. For example, at least a portion of the scratch protrusions140may protrude from the bending portion134, and at least other portions of the scratch protrusions140may protrude from other positions of the interference portion130.

The plurality of scratch protrusions140may be arranged to be spaced apart from each other. However, the present disclosure is not limited thereto, and the plurality of scratch protrusions140may be arranged to be in contact with each other.

The plurality of scratch protrusions140may be provided to scratch the outer surface of the interference wall240when the interference portion130is in contact with the interference wall240. The plurality of scratch protrusions140may penetrate the coating layers240band240c, respectively, and may be in contact with the conductive layer240aby removing the coating layers240band240capplied to the outer surface of the interference wall240, respectively. In other words, the plurality of scratch protrusions140may each form the scratch S, thereby forming a plurality of scratches S on the interference wall240. However, the present disclosure is not limited thereto, and when the plurality of scratch protrusions140is arranged to be in contact with each other, the plurality of scratch protrusions140may slide with respect to the interference wall240and form one large scratch S.

The plurality of scratch protrusions140may be manufactured by burring processing as shown inFIGS.15and16, respectively. However, the present disclosure is not limited thereto, and the plurality of scratch protrusions140may be manufactured using various methods.

FIGS.17and18illustrate that the mounting member1000includes two scratch protrusions140, but is not limited thereto. Alternatively, the mounting member1000may include three or more scratch protrusions140. The number of scratch protrusions140provided on the mounting member1000may be selected in various ways.
