Description

Fixing device for the circuit board

[0001] The embodiment relates to a fixing device for a substrate.

[0002] The electronic device includes a substrate that supports and connects various electronic components. The substrate can be fixed to the electronic device through a fixing device.

[0003] As an example of a fixing device, there is a method of using fastening members such as screws or bolts. By inserting the fastening member into a pre-formed hole in the substrate or support structure and rotating it, the substrate can be fixed to the electronic device. However, in order to rotate the fastening member, a separate process and a device or equipment for performing the process must be provided.

[0004] Furthermore, although the electronic device can be secured using a clip-type tool attached to the substrate, this method is simpler in configuration and process than the rotary fastening method; however, the complex shape of the clip makes manufacturing difficult, and the unstable contact between the clip and the electronic device's support structure results in reduced bonding strength. In particular, while grounding of the substrate can be achieved through a fixing device, a critical problem can arise where grounding fails if the clip separates from the electronic device's support structure.

[0005] Accordingly, the embodiment aims to solve the above-mentioned problems by providing a substrate fixing device capable of achieving stable grounding while securing the fixing force between the substrate and the electronic device.

[0006] The problems that the embodiments aim to solve are not limited to those mentioned above, and other problems not mentioned herein will be clearly understood by those skilled in the art from the description below.

[0007] An embodiment for achieving the above objective may provide a fixing device comprising a body, a leg portion that is bent from the body and coupled to a substrate, and a clip portion that extends from the body, wherein the clip portion is positioned between the substrate and a fixed object to form a plurality of contact areas that contact the fixed object, and the plurality of contact areas are positioned spaced apart from each other.

[0008] The above substrate includes a first hole, and the fixed object can pass through the first hole and come into contact with the clip portion.

[0009] When the clip portion is in contact with the fixed object, the stopper formed on the fixed object contacts the inner wall of the first hole, thereby restraining the fixed object in a direction opposite to the insertion direction of the fixed object toward the clip portion.

[0010] The plurality of contact areas may be spaced apart from each other in a direction perpendicular to the insertion direction of the fixed object facing the clip portion and the plane of the substrate.

[0011] It includes a curved portion bent toward the substrate, and the curved portion can form a plurality of contact areas with the object.

[0012] The above substrate includes a first hole through which an object penetrates, and the end of the curved portion may be located in the hole.

[0013] The clip portion includes a first clip extending from the body and a second clip extending from the body, and the first clip and the second clip may be formed to be spaced apart in a direction perpendicular to the insertion direction of the fixed object facing the clip portion and the plane of the substrate.

[0014] The above-mentioned curved portion may include an upward portion formed to extend away from the body and away from the substrate, and a downward portion formed to approach the substrate.

[0015] Among the plurality of contact areas, the first clip forms a first contact area, and among the plurality of contact areas, the second clip forms a second contact area, and the first contact area and the second contact area can be formed symmetrically.

[0016] The above downward portion may include a first part that is bent toward the substrate from the above upward portion, and a second part that is bent toward the substrate from the first part.

[0017] The above substrate includes a first hole through which the fixed object passes, and the first hole includes a first-1 hole and a first-2 hole extending from the first-1 hole in the insertion direction of the fixed object toward the clip portion, and the width of the second hole may be smaller than the width of the first-1 hole.

[0018] A part of the fixed object may be located in the first-1 hole, and another part of the fixed object may be located in the first-2 hole.

[0019] The clip portion includes a first clip and a second clip, and the first clip and the second clip may be positioned with the first-second hole in between.

[0020] The device further includes a protrusion that protrudes more than the leg portion from the body in the insertion direction of the fixed object toward the clip portion, wherein the protrusion is located on the same plane as the body and the leg portion can be bent toward the substrate.

[0021] The above leg portion includes a first leg and a second leg spaced apart in a direction perpendicular to the insertion direction of the fixed object facing the clip portion, and the protrusion may be located between the first leg and the second leg.

[0022] According to the embodiment, by fixing the substrate to an electronic device (fixed object) in a sliding manner through a clip portion disposed on the substrate, the configuration for fixing is simple and no separate equipment for fixing is required, thereby providing the advantage of simplifying the manufacturing equipment and manufacturing process.

[0023] According to an embodiment, the clip portion forms a plurality of contact areas with the fixed object and the contact areas are spaced apart from each other, so that even if the clip portion moves, contact with the fixed object is stably maintained, thereby providing the advantage of securing stable grounding.

[0024] According to the embodiment, when the clip portion is in contact with the object to be fixed, the inner wall of the hole of the substrate contacts the object to be fixed, thereby preventing the object to be fixed from coming loose, which has the advantage of increasing the bonding strength between the substrate and the object to be fixed.

[0025] According to an embodiment, since the end of the clip portion is formed to be bent toward the substrate, during the process of the object to be fixed sliding, the end of the clip portion enters between the object to be fixed and the substrate, thereby providing the advantage of facilitating contact between the fixing device and the object to be fixed.

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0040] However, the technical concept of the present invention is not limited to some of the described embodiments but can be implemented in various different forms, and within the scope of the technical concept of the present invention, one or more of the components among the embodiments may be selectively combined or substituted.

[0041] In addition, terms used in the embodiments of the present invention (including technical and scientific terms) may be interpreted in a sense that is generally understood by those skilled in the art to which the present invention belongs, unless explicitly and specifically defined otherwise. Terms that are commonly used, such as terms defined in advance, may be interpreted in consideration of their meaning in the context of the relevant technology.

[0042] Furthermore, the terms used in the embodiments of the present invention are for the purpose of describing the embodiments and are not intended to limit the present invention.

[0043] In this specification, the singular form may include the plural form unless specifically stated otherwise in the text, and when described as “at least one of A and B, C (or more than one of them),” it may include one or more of all combinations that can be formed from A, B, and C.

[0044] In addition, terms such as first, second, A, B, (a), (b), etc. may be used when describing the components of the embodiments of the present invention.

[0045] These terms are intended merely to distinguish a component from other components and are not limited by the essence, order, sequence, etc. of the component.

[0046] And, where it is stated that a component is 'connected', 'combined', or 'joined' to another component, this may include not only cases where the component is directly connected, combined, or joined to the other component, but also cases where it is 'connected', 'combined', or 'joined' due to another component located between the component and the other component.

[0047] Furthermore, when described as being formed or placed on the “top or bottom” of each component, “top or bottom” includes not only cases where two components are in direct contact with each other, but also cases where one or more other components are formed or placed between the two components. Additionally, when expressed as “top or bottom,” it may include the meaning of a downward direction as well as an upward direction relative to a single component.

[0048] Hereinafter, the fixed object may be a plate, a bracket, or various chassis structures capable of grounding in conjunction with the connection, provided for connection to an electronic device. The fixing device for the substrate (hereinafter referred to as the fixing device) is intended to fix the substrate to the fixed object. Additionally, the fixing device is intended for grounding and may be made of a conductive material. The fixed object may also be made of a conductive material for grounding. Therefore, it is important for the fixing device to maintain contact with the fixed object for grounding as well as for connection.

[0049] Simplifying the structure of a fixing device can reduce the manufacturing process and time, but it is difficult to ensure the bonding strength and contact safety between the substrate and the object to be fixed. To fundamentally solve this problem, the fixing device according to the embodiment is configured to allow the substrate and the object to be fixed to be assembled in a sliding manner, and is configured to form multiple contact areas between the fixing device and the object to be fixed, thereby ensuring both fixing force and grounding stability.

[0050] FIG. 1 is a drawing illustrating a substrate including a fixing device and a fixed object disposed on the chassis of an electronic device. It is a drawing illustrating the fixing of the substrate to the fixed object. In the drawings below, the x-axis represents the longitudinal direction of the fixing device, the y-axis represents the width direction of the fixing device, and the z-axis represents the height direction of the fixing device.

[0051] Referring to FIG. 1, a fixing device (10) according to an embodiment is installed on a substrate (20). With the fixing device (10) installed on the substrate (20), a fixing object (30) can be aligned with the fixing device (10), and then the fixing device (10) can be fastened to the fixing object (30) in a sliding manner. For example, as shown in the drawing, with the fixing object (30) inserted into the fixing device (10), if the substrate (20) or the fixing object (30) is moved along the height direction (z), the fixing device (10) is fastened to the fixing object (30), thereby allowing the substrate (20) to be fixed to the fixing object (30). Consequently, when the substrate (20) is fixed to the fixing object (30), the substrate (20) can be fixed to the chassis (1) of an electronic device.

[0052] The fixing device (10) is fixed to the substrate (20). At this time, the fixing device (10) can be electrically connected to the circuit of the substrate (20). Grounding is achieved by the fixing device (10) and the fixed object (30) coming into contact. When current leaks from the substrate (20) or an overcurrent occurs, current can flow through the fixing device (10) and the fixed object (30) to the chassis (1) of the electronic device. Such a fixing device (10) can be installed at various points on the substrate (20). The position of the fixing device (10) is determined to correspond to the position of the fixed object (30).

[0053] FIG. 2 is a drawing illustrating the process of fixing a substrate (20) to a fixed object (30) using a fixing device (10) according to an embodiment.

[0054] Referring to (a) in FIG. 2, in order to fix the substrate (20) to the fixed object (30), first, the fixing device (10) and the fixed object (30) are aligned so that the fixing device (10) faces the fixed object (30). Then, as shown in (b) of FIG. 2, the fixed object (30) is inserted into the substrate (20). Next, as shown in (c) of FIG. 2, the fixed object (30) is moved toward the fixing device (10), and the fixed object (30) is fastened to the fixing device (10). At this time, the direction in which the fixed object (30) is inserted toward the fixing device (10) is indicated as the same direction as F1 in FIG. 2, which corresponds to the height direction (z) of the fixing device (10) in the drawing. The direction perpendicular to the insertion direction of the object to be fixed (30) facing the fixing device (10) is indicated as F2 in FIG. 2, which corresponds to the width direction (y) of the substrate (20) in the drawing. In this way, since the substrate (20) and the object to be fixed (30) are joined in a sliding manner without rotating or tightening, the process of fixing the substrate (20) to the object to be fixed (30) is simple, and the structure of the fixing device (10) can be simplified.

[0055] As illustrated in FIG. 2(a), the fixed object (30) is fitted onto the substrate (20) before being fastened to the fixing device (10), and the substrate (20) has a structure for accommodating the fixed object (30).

[0056] FIG. 3 is a plan view showing a substrate (20), and FIG. 4 is a drawing showing a fixing device (10) coupled to the substrate (20).

[0057] Referring to FIGS. 2 to 4, the substrate (20) includes a first hole (H1) for receiving a fixed object (30). Before the fixed object (30) is fastened to the fixing device (10), a portion (31) of the fixed object (30) penetrates the first hole (H1) from one side of the substrate (20) to the other side. Here, one side of the substrate (20) refers to the direction from the substrate (20) toward the fixed object (30), and the other side of the substrate (20) refers to the direction opposite to the direction from the substrate (20) toward the fixed object (30). The portion (31) of the fixed object (30) refers to the portion of the fixed object (30) exposed through the first hole (H1) from the other side of the substrate (20), which is the area fastened to the fixing device (10). The size and shape of the first hole (H1) may be formed to correspond to a portion of the fixed object (30) (31). The shape of the portion of the fixed object (30) (31) is not limited to the drawing and can be implemented in various ways, and the shape of the first hole (H1) may also be changed accordingly.

[0058] The first hole (H1) may include a first-1 hole (H1a) and a first-2 hole (H1b). The first-2 hole (H1b) may extend from the first-1 hole (H1a) in the insertion direction of the object to be fixed (30) toward the fixing device (10) installed on the substrate (20). The width (W2) of the first-2 hole may be smaller than the width (W1) of the first-1 hole (H1a). In this case, “width” is based on the width direction (y). Overall, the size of the first-2 hole (H1b) is smaller than the size of the first-1 hole (H1a). The first-2 hole (H1b) is intended to accommodate a protruding portion in a part area (31) of the object to be fixed (30). The shape of the first hole (H1) corresponds to a portion (31) of the fixed object (30) that penetrates the first hole (H1), and is intended to improve assemblability with the substrate (20) and the fixing device (10).

[0059] Meanwhile, the substrate (20) may include a second hole (H2). The second hole (H2) is where the leg portion (200) of the fixing device (10) is coupled. The second hole (H2) may be located adjacent to the first hole (H1). The second hole (H2) may be aligned with the first hole (H1) with respect to the width direction (y). There may be multiple second holes (H2). For example, two second holes (H2) may be spaced apart along the width direction (y). Two second holes (H2) may be located at the same position with respect to the height direction (z). The shape and size of the second hole (H2) may correspond to the shape and size of the cross-section of the leg portion (200) of the fixing device (10).

[0060] Referring to FIG. 4, the leg portion (200) of the fixing device (10) can be fitted into the second hole (H2). When the leg portion (200) is inserted into the second hole (H2), the body (100) of the fixing device (10) can be positioned facing the substrate (20) and can be in contact with the substrate (20) or positioned slightly spaced apart from the substrate (20). Additionally, the clip portion (300) of the fixing device (10) can also be positioned facing the substrate (20), and the end of the clip portion (300) can be positioned in the first hole (H1).

[0061] When the fixing device (10) is coupled to the substrate (20) and the object to be fixed (30) is inserted in a sliding manner, it elastically deforms and presses the object to be fixed (30), thereby fixing the substrate (20) to the object to be fixed (30). The specific configuration of the fixing device (10) for this purpose is as follows.

[0062] FIG. 5 is a perspective view of the fixing device (10), FIG. 6 is a side view of the fixing device (10), and FIG. 7 is a top view of the fixing device (10).

[0063] Referring to FIGS. 5 to 7, the fixing device (10) may include a body (100), a leg portion (200), and a clip portion (300). These body (100), leg portion (200), and clip portion (300) may be described separately according to their shape and functional characteristics, but may be a single means connected vertically to each other and made of a conductive material.

[0064] The body (100) may be a flat plate.

[0065] The leg portion (200) may be formed by extending from one end (top in the drawing) of the body (100). The leg portion (200) is intended to secure the fixing device (10) to the substrate (20). The leg portion (200) may be formed by bending at one end of the body (100). For example, the leg portion (200) may be bent perpendicularly to the body (100) so as to be bent from the body (100) toward the substrate (20). The leg portion (200) penetrates the substrate (20). The end of the leg portion (200) that penetrates the substrate (20) may protrude from the substrate (20). There may be multiple such leg portions (200). For example, a first leg (200A) and a second leg (200B) may be positioned spaced apart in the width direction (y). The first leg (200A) and the second leg (200B) can be formed symmetrically with respect to an imaginary reference line (CL in FIG. 7) passing through the center of width of the body (100).

[0066] This is to maintain the balance of the fixing device (10) in the width direction (y). That is, when the fixing device (10) is combined with the object to be fixed (30), it is to prevent the fixing device (10) and the object to be fixed (30) from shaking or tilting to one side and separating from each other. In addition, since the leg portion (200) is positioned symmetrically with respect to the width direction (y), stable coupling between the substrate (20) and the fixing device (10) can be secured regardless of the direction of vibration transmitted from the outside and the direction of impact generated during the process of contact with the object to be fixed (30).

[0067] The clip portion (300) is elastically deformed to press the object to be fixed (30). The clip portion (300) may be extended from the other end (bottom in the drawing) of the body (100). The clip portion (300) is extended from the body (100) in a cantilevered form and is elastically deformed when an external force is applied. The restoring force generated during the elastic deformation of the clip portion (300) becomes the force that presses the object to be fixed (30). This clip portion (300) may include a bend portion (310) to increase the pressing force on the object to be fixed (30). The bend portion (310) may be implemented as the entire or a part of the area (31) of the clip portion (300). The bend portion (310) has a shape that is bent toward the substrate (20). In FIG. 5, the convex part of the bend portion (310) may come into contact with the object to be fixed (30).

[0068] Specifically, the curved portion (310) may include an upward portion (311) and a downward portion (312). The upward portion (311) has a curved shape and is formed to move away from the substrate (20) with respect to the longitudinal direction (x). The downward portion (312) has a curved shape and is formed to move closer to the substrate (20) with respect to the longitudinal direction (x). The downward portion (312) may include a first part (312a) and a second part (312b). The first part (312a) may be formed by bending from the upward portion (311) toward the substrate (20). The second part (312b) may be formed by bending from the first part (312a) toward the substrate (20). The second part (312b) may be formed with a larger angle of inclination toward the substrate (20) than the first part (312a).

[0069] The clip portion (300) has a shape that is bent toward the substrate (20) overall, and the bent portion (310) can be positioned away from the substrate (20) in the absence of external force. The downward portion (312) of the bent portion (310) is positioned to face the object to be fixed (30), and when the fixing device (10) and the object to be fixed (30) are fastened together, it begins to make contact with the object to be fixed (30).

[0070] Referring to FIG. 7, the clip portion (300) may include a first clip (300A) and a second clip (300B). The first clip (300A) and the second clip (300B) may be positioned spaced apart from each other in the width direction (y). The first clip (300A) and the second clip (300B) may form a slot (SL) that secures a space in the width direction (y) into which a fixed object (30) can be inserted. At this time, the end of the side wall of the first clip (300A) corresponding to the entrance of the slot (SL) and the end of the side wall of the first clip (300A) may form an inclined surface (ET) such that the entrance widens as it faces the entrance. When these first clip (300A) and the second clip (300B) are inserted into the slot (SL), they guide the fixed object (30) to enter the entrance smoothly.

[0071] These first clip (300A) and second clip (300B) each form a contact area with the object to be fixed (30). In particular, since the first clip (300A) and the second clip (300B) are formed symmetrically with respect to a reference line (CL) passing through the center of the width direction (y) of the body (100), a balanced contact area can be formed with respect to the object to be fixed (30) in the width direction (y). Although the number of clips of the clip portion (300) is exemplified as two, the present invention is not limited thereto, and the number of clips can be varied.

[0072] Meanwhile, the fixing device (10) may further include a protrusion (400) extending from the body (100). The protrusion (400) may extend from one end of the body (100) to which the leg portion (200) extends. The protrusion (400) may be a flat plate member. The protrusion (400) may be located on the same plane as the body (100). The protrusion (400) may be located between the first leg (200A) and the second leg (200B) in the width direction (y). A round groove (G) may be formed between the protrusion (400) and the leg portion (200). This groove (G) is located between the leg portion (200) and the protrusion (400) to prevent the protrusion (400) from being deformed when the leg portion (200) is bent.

[0073] FIG. 8 is a drawing showing a state in which a fixing device (10) and a fixing object (30) are combined and a substrate (20) is fixed to the fixing object (30), and FIG. 9 is a drawing showing a state in which a fixing device (10) and a fixing object (30) are combined to form a contact area.

[0074] Referring to FIGS. 7 to 9, when the substrate (20) or the fixed object (30) slides while the fixed object (30) is inserted into the first hole (H1) of the substrate (20), the fixing device (10) forms a plurality of contact areas (C1, C2) with the fixed object (30). Since there are multiple clip parts (300), contact areas (C1, C2) can be formed for each clip in correspondence with the fixed object (30).

[0075] For example, the first clip (300A) can form a first contact area (C1), and the second clip (300B) can form a second contact area (C2). Since the first clip (300A) and the second clip (300B) are positioned symmetrically with respect to the reference line (CL), the first contact area (C1) and the second contact area (C2) are also formed symmetrically with respect to the reference line (CL). In this way, since the contact areas (C1, C2) of the fixing device (10) and the fixing object (30) are distributed in a balanced manner with respect to the width direction (y), when the fixing device (10) and the fixing object (30) are combined, neither side can lift up, and a stable contact state can be maintained.

[0076] In addition, structural safety can be secured so that the fixing device (10) and the fixed object (30) are combined, preventing the fixing device (10) from moving due to vibrations or external forces transmitted from the outside. As such, maintaining a stable contact state between the fixing device (10) and the fixed object (30) is a very important factor not only for securing fixing force but also for securing grounding performance.

[0077] Meanwhile, when the fixed object (30) is inserted into the first hole (H1) and the coupling to the fixing device (10) is completed, the stopper (ST) formed on the fixed object (30) is positioned in the first hole (H1) to restrain the substrate (20) so that it does not come out of the fixed object (30) in the height direction (z). This will be explained together with the coupling process of the fixing device (10) and the fixed object (30) below with reference to the drawings.

[0078] FIG. 10 is a side view of the state in which the fixing device (10) and the fixing object (30) move for coupling, and FIG. 11 is a side view of the state in which the clip part (300) of the fixing device (10) begins to contact the fixing object (30).

[0079] Referring to FIGS. 10 and 11, when the substrate (20) or the object to be fixed (30) moves in the height direction (z), the object to be fixed (30) comes into close proximity to the fixing device (10). The downward portion (312) of the clip portion (300) faces the object to be fixed (30). As shown in FIG. 11, as the downward portion (312) of the clip portion (300) comes into contact with the object to be fixed (30), the clip portion (300) enters between the substrate (20) and the object to be fixed (30). At this time, the clip portion (300) is deformed to have a restoring force while being pressed by the object to be fixed (30). When the clip portion (300) enters between the substrate (20) and the fixed object (30), the second part (312b) of the downward portion (312) naturally enters between the substrate (20) and the fixed object (30) while touching the inclined surface (31b) formed on the fixed object (30), and subsequently, the first part (312a) of the downward portion (312) touches the inclined surface (31b) of the fixed object (30). During this process, the clip portion (300) enters between the substrate (20) and the fixed object (30) while being pressed.

[0080] FIG. 12 is a side cross-sectional view based on AA of FIG. 8 showing the state in which the fixing device (10) and the fixing object (30) are connected, and FIG. 13 is a side cross-sectional view based on BB of FIG. 8 showing the state in which the fixing device (10) and the fixing object (30) are connected.

[0081] Referring to FIGS. 10 to 12, when the clip portion (300) fully enters between the substrate (20) and the object to be fixed (30), the clip portion (300) is pressed, thereby securing a fixing force by pressing the object to be fixed (30) in a direction away from the substrate (20). Since the leg portion (200) is coupled to the second hole (H2) of the substrate (20), when the clip portion (300) is pressed, sufficient restoring force to press the object to be fixed (30) can be secured.

[0082] At this time, since the stopper (ST) of the fixed object (30) is in contact with the inner wall (21) of the first hole (H1), the fixed object (30) in the drawing is not pushed downward. As seen in the drawing, the upper part of the fixed object (30) is also blocked by the fixing device (10) or the inner wall of the first hole (H1), so the fixed object (30) is prevented from detaching from the substrate (20).

[0083] As illustrated in FIG. 13, the protrusion (400) can come into contact with the substrate (20). The protrusion (400) prevents the fixing device (10) from being lifted during the process of contact between the clip part (300) and the object to be fixed (30). This is because the protrusion (400) is located on the opposite side of the clip part (300) and is in contact with the substrate (20).

[0084] Thus, the fixing device (10) according to the embodiment is coupled to the object to be fixed (30) on the substrate (20) in a sliding manner through the clip part (300) disposed on the substrate (20), thereby making the configuration for fixing simple and eliminating the need for separate equipment for fixing. In particular, the clip part (300) forms a plurality of contact areas (C1, C2) with the object to be fixed (30), and the contact areas (C1, C2) are spaced apart from each other, so that even if the clip part (300) moves, contact with the object to be fixed (30) is stably maintained, thereby ensuring stable grounding. Furthermore, while the clip part (300) is in contact with the object to be fixed (30), the inner wall (21) of the first hole (H1) of the substrate (20) contacts the object to be fixed (30), thereby preventing the object to be fixed (30) from coming out.
