Description

Technical Field

[0001] This application relates to locking components, and more specifically, to locking components for tool-less installation of compression-attached memory modules (CAMMs). Furthermore, this application also relates to electronic systems including such locking components. Background Technology

[0002] Compact Attached Memory Modules (CAMMs) are a new type of memory module design primarily used in compact devices such as laptops and workstations. A CAMM includes a connector located between substrates. CAMMs are connected to the printed circuit board (PCB) via mechanical crimping. Traditionally, CAMMs are positioned parallel to the PCB surface and secured using mechanical fasteners such as screws. These fasteners apply downward pressure to the module, causing contact between the mating surfaces of the connector. However, using tools like mechanical fasteners carries risks. For example, when an operator is installing the module onto the PCB surface, an accident could occur, causing the mechanical fastener, such as a screw, to fall into the computer chassis.

[0003] Furthermore, the substrate generates more heat due to high bandwidth and high capacity transmission, thus requiring a heatsink to be installed above the substrate (e.g., a printed circuit board) for heat dissipation. In this case, it is difficult to use conventional mechanical fasteners to mount the compression-attached memory module to the printed circuit board and provide sufficient compression.

[0004] Therefore, there is a need for a component that can mount a compressed attached memory module to a printed circuit board without the aid of tools, and that can provide sufficient compression when a heat sink is mounted on top of the printed circuit board. Utility Model Content

[0005] This section provides a general summary of the application, rather than a full disclosure of the entire scope or all features of the application.

[0006] In view of the problems existing in the above-mentioned related technologies, there is a need to improve the connection method between the compressed attached memory module and the substrate.

[0007] Some embodiments of this application provide a locking member configured to mount a first substrate to a second substrate in a tool-free manner. The locking member may include: a first support base configured to engage with the second substrate; a conductive cover configured to be rotatably connected to the first support base; and a conductive beam including a plurality of protrusions to be engaged with the first substrate, at least one first protrusion being fixedly connected to the conductive cover, and at least one second protrusion being displaceable relative to the conductive cover.

[0008] In some exemplary embodiments, the locking member may further include a fastener, the first substrate may be configured to be disposed above the second substrate, the first support base may be disposed in the length direction of the second substrate adjacent to one end of the first substrate in the length direction, and when the fastener extends through a connecting hole in the first end of the conductive cover in the length direction and is pressed toward the second substrate, the opposite second end of the conductive cover may be rotated about a rotation axis relative to the first support base until the first end of the conductive cover engages with the second substrate, thereby positioning the first and second protrusions of a plurality of protrusions into corresponding first positioning holes in the first substrate.

[0009] In some exemplary embodiments, the locking member may further include a second support base and a fastener. The second support base may be configured to engage with a second substrate. The first substrate may be configured to be disposed above the second substrate. The first and second support bases may be arranged along the length of the second substrate adjacent to two ends of the first substrate in the length direction. When the fastener extends through a connection hole in the first end of the conductive cover in the length direction and is pressed toward the second support base engaged with the second substrate, the opposite second end of the conductive cover may rotate about a rotation axis relative to the first support base, thereby connecting the first end of the conductive cover to the second support base by the fastener, and positioning the first and second protrusions of a plurality of protrusions into corresponding first positioning holes in the first substrate.

[0010] With the locking member provided in this application, at least one first protrusion of the plurality of protrusions of the conductive beam is used as a fixed fulcrum because it is fixedly connected to the conductive cover. The second protrusion closest to the first support base can maintain contact with the first substrate after first contacting it and can be displaced relative to the conductive cover. In particular, it can rotate relative to the conductive cover about the connecting axis, so that there is no large interaction force between the second protrusion and the first substrate. In the context of this application, "no large interaction force" can specifically mean that the interaction force between the second protrusion that first contacts the first substrate and the corresponding first substrate will not reach the level that causes the first substrate to suffer functional or effect degradation due to uneven stress. In other words, during the assembly of the locking member, the second protrusion that first contacts the first substrate can maintain contact with the corresponding first substrate and generate a certain interaction force, but because the second protrusion can be displaced relative to the conductive cover, the interaction force is relatively small, particularly small enough to not "hinder" the first substrate. Therefore, the multiple protrusions of the conductive beam work as a whole on a principle similar to a "seesaw", thereby solving the problem of uneven force on the first substrate that may occur due to the first and second protrusions being pressed into the corresponding first positioning holes of the first substrate in turn.

[0011] In some exemplary embodiments, the plurality of protrusions may include at least two second protrusions located on either side of at least one first protrusion along the length of the conductive beam.

[0012] In some exemplary embodiments, at least two second protrusions may be arranged symmetrically on both sides of at least one first protrusion along the length of the conductive beam.

[0013] In some exemplary embodiments, at least one first protrusion may be located at the central portion of the conductive beam along its length.

[0014] In some exemplary embodiments, at least one first protrusion of the plurality of protrusions may be located at the central portion of the conductive beam along the length direction of the conductive beam, and at least two second protrusions of the plurality of protrusions may be symmetrically arranged on both sides of at least one first protrusion along the length direction of the conductive beam.

[0015] In some exemplary embodiments, the shape and size of the first protrusion among the plurality of protrusions may be the same as the shape and size of the second protrusion.

[0016] In some exemplary embodiments, when the conductive cover is engaged to the second substrate, each of the plurality of protrusions can be simultaneously positioned in a corresponding first positioning hole in the first substrate. In the context of this application, "simultaneously positioned in the first positioning hole" can specifically mean that the plurality of protrusions are substantially simultaneously pressed into a portion of the first positioning hole. It is understood that a second protrusion that initially contacts the first substrate remains in contact with the first substrate throughout the assembly of the locking member; such contact may involve a small portion of the second protrusion entering the first positioning hole, but this does not mean that the second protrusion has been "positioned" in the first positioning hole.

[0017] In some exemplary embodiments, when the conductive cover is engaged to the second support base, each of the plurality of protrusions can be inserted into a corresponding first positioning hole in the first substrate.

[0018] In some exemplary embodiments, the fastener may be a thumb screw.

[0019] The locking member provided in this application uses a thumb screw passing through the first end of the conductive beam to press the first end of the conductive cover, causing the conductive cover to rotate relative to the first support base about a rotation axis until the conductive cover is engaged with the second support base and / or the second substrate. In this way, the locking member utilizes the lever principle to reduce the amount of force required on the conductive cover, thereby improving the efficiency of mounting the first substrate to the second substrate. Furthermore, during the mounting of the first substrate to the second substrate, only the thumb screw needs to be applied; that is, the operator only needs to press the thumb screw, which extends through the connection hole of the conductive cover, toward the second support base and / or the second substrate, causing the conductive cover to contact the second support base and / or the second substrate, and then tighten the thumb screw, thereby inserting the multiple protrusions of the conductive beam into the corresponding first positioning holes of the first substrate, so as to mount the first substrate to the second substrate without the need for any other additional tools.

[0020] In some exemplary embodiments, at least one first protrusion of the conductive beam may protrude from the lower surface of the conductive beam, the conductive beam includes a pair of grooves on the upper surface of the conductive beam opposite to the at least one first protrusion, and the conductive beam also includes a spacer between the pair of grooves; the conductive cover includes a pair of lugs at positions corresponding to the pair of grooves of the conductive beam, the pair of lugs being spaced apart by a distance corresponding to the spacer; the pair of lugs are placed in the pair of grooves, the spacer is placed between the pair of lugs, and a connecting shaft extends through holes in the pair of lugs and holes in the spacer, thereby fixing at least one first protrusion to the conductive cover.

[0021] Other embodiments of this application provide an electronic system. The electronic system may include: a first substrate including a plurality of first positioning holes; a second substrate including a plurality of second positioning holes, the first substrate being located above the second substrate; a connector disposed between the first substrate and the second substrate and connecting the first substrate and the second substrate; and a locking member according to the above embodiments.

[0022] In some exemplary embodiments, the connector may include an upper protrusion and a lower protrusion protruding from the upper and lower surfaces of the connector, respectively. The upper protrusion is inserted into a portion of a corresponding first positioning hole in the first substrate, and the lower protrusion is inserted into a corresponding second positioning hole in the second substrate, thereby connecting the first substrate to the second substrate.

[0023] In some exemplary embodiments, the lower surface of the second substrate may be attached with a backplate having a shielding device to prevent light from inside the electronic device from leaking to the outside.

[0024] In some exemplary embodiments, the masking device may be a melanin sheet.

[0025] In some exemplary embodiments, each of the plurality of protrusions may be inserted into a portion of a corresponding first positioning hole in the first substrate.

[0026] Further embodiments of this application provide a locking member. The locking member can be configured to mount a first substrate to a second substrate in a tool-free manner. The locking member may include: a locator configured to engage with the second substrate; a pawl configured to engage with the first substrate; and an elastic member configured to engage the pawl with the locator.

[0027] In some exemplary embodiments, the locking member may further include a fastener, which may include a head and a shank, the head engaging with a pawl, the shank extending through the pawl, the resilient member, and the locator, the distal portion of the shank being threaded, at least a portion of the distal portion being fastened in use to a corresponding threaded hole in the substrate.

[0028] In some exemplary embodiments, the locator may be configured to engage with the second substrate in use such that it is positioned in the length direction of the second substrate adjacent to the end of the first substrate in the length direction.

[0029] In some exemplary embodiments, the locator may include a hollow portion, a first end of the locator may include a seating portion, an elastic member is disposed in the hollow portion on the seating portion, and a pawl is disposed on the elastic member.

[0030] In some exemplary embodiments, the pawl may include a curved first portion and a linearly extending second portion, the first portion being formed in a generally L-shaped form including a long side portion and a short side portion, the second portion extending from the long side portion of the first portion into the hollow portion of the locator to abut against an elastic member, and the short side portion of the first portion being configured to engage with a first substrate.

[0031] In some exemplary embodiments, after the pawl is rotated toward the first substrate and positioned above the first substrate, the fastener is tightened, and the second portion of the pawl is pressed toward the second substrate against the elastic force of the elastic member, thereby adjusting the distance between the lower edge of the long side portion of the first portion of the pawl and the second end of the locator opposite to the first end, as well as the distance between the short side portion of the first portion of the pawl and the second substrate.

[0032] In some exemplary embodiments, the second end of the positioner may include locating grooves opposite each other in the circumferential direction, one of the locating grooves facing one end of the first substrate in the longitudinal direction during use; the second portion of the pawl may include opposing bosses projecting in the radial direction, one of the bosses facing one end of the first substrate in the longitudinal direction during use; after the pawl is rotated toward and positioned above the first substrate and the fastener is tightened, the bosses are inserted into the locating grooves. In this way, precise positioning of the pawl relative to the positioner is provided, thereby making the operation of the locking member more precise.

[0033] In some exemplary embodiments, the second end of the positioner may further include a protrusion adjacent to the positioning groove in the positioning groove that faces the first substrate during use, the protrusion protruding toward the pawl; when the pawl is rotated toward the first substrate and positioned above the first substrate, the boss in the pawl facing the first substrate contacts the protrusion, thereby limiting further rotation of the pawl.

[0034] In some exemplary embodiments, the fastener may be a thumbscrew. In this way, the operator only needs to rotate the pawl toward the first substrate and then tighten the head of the thumbscrew to engage the pawl with the first substrate, thereby mounting the first substrate to the second substrate without any other additional tools.

[0035] Some embodiments of this application provide an electronic system that may include: a first substrate including a plurality of first positioning holes; a second substrate including a plurality of second positioning holes, the first substrate being located above the second substrate; a connector disposed between the first substrate and the second substrate and connecting the first substrate and the second substrate; and a locking member according to the above embodiments.

[0036] In some exemplary embodiments, the connector may include an upper protrusion and a lower protrusion protruding from the upper and lower surfaces of the connector, respectively. The upper protrusion is inserted into a portion of a corresponding first positioning hole in the first substrate, and the lower protrusion is inserted into a corresponding second positioning hole in the second substrate, thereby connecting the first substrate to the second substrate.

[0037] In some exemplary embodiments, the lower surface of the second substrate may be attached with a backplate having a shielding device to prevent light from inside the electronic device from leaking to the outside.

[0038] In some exemplary embodiments, the masking device may be a melanin sheet.

[0039] In some exemplary embodiments, the electronic system may also include a heat sink disposed on top of the first substrate, wherein after the pawl is rotated toward the heat sink and positioned above the heat sink, a fastener is tightened such that the pawl engages with the heat sink.

[0040] In some exemplary embodiments, the electronic system may also include a thermal pad disposed between the heat sink and the first substrate and connecting the heat sink and the first substrate to further improve heat dissipation.

[0056] One aspect of this application provides a locking member 10 configured to mount a first substrate 20 to a second substrate 30 in a tool-free manner. (See also...) Figures 1 to 4 In some exemplary embodiments, the locking member 10 includes: a first support base 11 configured to engage with a second substrate 30; a conductive cover 12 configured to be rotatably coupled to the first support base 11; and a conductive beam 13 including a plurality of protrusions to be engaged with the first substrate 20, at least one first protrusion 131 of the plurality of protrusions being fixedly connected to the conductive cover 12, and at least one second protrusion 132 of the plurality of protrusions being displaceable relative to the conductive cover 12.

[0057] In some exemplary embodiments, the locking member further includes a fastener 15, the first substrate 20 being configured to be disposed above the second substrate 30, and the first support base 11 being arranged along the length of the second substrate 30 adjacent to one end of the first substrate 20 along its length. In this example, when the fastener 15 extends through the connection hole 123 in the first end 121 along the length of the conductive cover 12 and is pressed toward the second substrate 30, the opposite second end 122 of the conductive cover 12 rotates about the rotation axis 16 relative to the first support base 11 until the first end 121 of the conductive cover 12 engages with the second substrate 30, thereby positioning the first protrusion 131 and the second protrusion 132 of the plurality of protrusions into corresponding first positioning holes 21 in the first substrate 20. In this way, the locking member 10 utilizes the lever principle to reduce the force required to be applied to the conductive cover 12, thereby improving the efficiency of mounting the first substrate 20 to the second substrate 30.

[0058] In some exemplary embodiments, reference is made to Figure 1 and Figure 2The locking member 10 also includes a second support base 14 and a fastener 15, the second support base 14 being configured to engage with the second substrate 30. When the fastener 15 extends through a connection hole 123 in the first end 121 along the length of the conductive cover 12 and is pressed toward the second support base 14 engaged with the second substrate 30, the opposite second end 122 of the conductive cover 12 rotates about the rotation axis 16 relative to the first support base 11, thereby connecting the first end 121 of the conductive cover 12 to the second support base 14 by the fastener 15, and positioning the first protrusion 131 and the second protrusion 132 of the plurality of protrusions into the corresponding first positioning holes 21 of the first substrate 20, in particular, positioning each of the plurality of protrusions substantially simultaneously into (e.g., pressing a majority of each protrusion into or fully pressing each protrusion into) the corresponding first positioning hole 21 of the first substrate 20.

[0059] In some exemplary embodiments, reference is made to Figure 1 and Figure 2 The first substrate 20 is configured to be disposed above the second substrate 30, and the first support base 11 and the second support base 14 are arranged along the length direction of the second substrate 30 to be adjacent to the two ends of the first substrate 20 in the length direction.

[0060] In some exemplary embodiments, when the first substrate 20 needs to be mounted to the second substrate 30, both the first support base 11 and the second support base 14 are engaged to the second substrate 30, and the fastener 15 extends through the connection hole 123 in the first end 121 of the conductive cover 12 and is pressed toward the second support base 14. At this time, the second end 122 of the conductive cover 12 rotates about the rotation axis 16 relative to the first support base 11 until the first end 121 of the conductive cover 12 is connected to the second support base 14 by the fastener 15, such that the first protrusion 131 and the second protrusion 132 of the plurality of protrusions are inserted into the corresponding first positioning hole 21 of the first substrate 20. That is, the conductive cover 12 is rotated about the rotation axis 16 relative to the first support base 11 by pressing the first end 121 of the conductive cover 12 with the fastener 15 until the conductive cover 12 is engaged to the second support base 14. In this way, the locking member 10 utilizes the lever principle to reduce the force that needs to be applied to the conductive cover 12, thereby improving the efficiency of mounting the first substrate 20 to the second substrate 30.

[0061] In some exemplary implementations, such as Figure 1 and Figure 2As shown, the first support base 11 is formed as a square block and includes a pair of flanges 111 located at the top of the block. The conductive cover 12 is rotatably connected to the first support base 11 via a rotation axis 16 extending through holes in the pair of flanges 111. In some examples, the first support base 11 may be formed in other shapes. For example, the first support base 11 may be formed in the form of a polygonal prism.

[0062] In some exemplary implementations, such as Figure 1 and Figure 2 As shown, the first support base 11 is configured to be engaged to the second substrate 30 by a fastener such as a screw 17. In some examples, the first support base 11 may also be configured to be engaged to the second substrate 30 in other ways. For example, the first support base 11 may be configured to be soldered to the second substrate 30.

[0063] In some exemplary implementations, such as Figure 1 As shown, the second support base 14 is configured to be engaged to the second substrate 30 by fasteners such as screws. In some examples, the second support base 14 may also be configured to be engaged to the second substrate 30 in other ways. For example, the second support base 14 may be configured to be soldered to the second substrate 30.

[0064] In some exemplary embodiments, the plurality of protrusions includes at least two second protrusions 132 located on either side of at least one first protrusion 131 along the length direction of the conductive beam 13. In some exemplary embodiments, the at least two second protrusions 132 are arranged substantially symmetrically on either side of at least one first protrusion 131 along the length direction of the conductive beam 13. In some exemplary embodiments, at least one first protrusion 131 is located at the central portion of the conductive beam 13 along its length direction.

[0065] In some exemplary embodiments, at least one first protrusion 131 of the plurality of protrusions is located at the central portion of the conductive beam 13 along its length, and at least two second protrusions 132 of the plurality of protrusions are arranged substantially symmetrically on both sides of the at least one first protrusion along the length of the conductive beam 13.

[0066] In some exemplary implementations, such as Figures 1 to 4As shown, there are multiple protrusions, specifically three protrusions. One of the three protrusions, a first protrusion 131, is located at the central portion of the conductive beam 13 along its length. The other two protrusions, second protrusions 132, are arranged substantially symmetrically on either side of the first protrusion along the length of the conductive beam 13. It is understood that in some alternative embodiments, two or more smaller first protrusions 131 may be used instead. Figures 1 to 4 The larger of the first protrusions 131 is shown. It is also understood that in other alternative embodiments, the arrangement of one or more first protrusions 131 on the conductive beam 13 can be varied according to design requirements. For example, in some examples, two or more first protrusions 131 can be arranged non-linearly (e.g., in a ring or triangular arrangement) at a substantially central position on the conductive beam 13. Furthermore, in Figures 1 to 4 In the exemplary embodiment shown, the other two second protrusions 132 of the three protrusions are arranged at two opposite ends of the conductive beam 13 along its length, the length of which corresponds to the length of the first substrate 20. This ensures that after the protrusions are inserted into the corresponding first positioning holes 21 of the first substrate 20, the force exerted by the protrusions on the first substrate 20 is evenly distributed on the first substrate 20, so that the first substrate 20 can be securely mounted to the second substrate 30.

[0067] In some exemplary implementations, such as Figure 4 As shown, the shape and size of the first protrusion 131 among the plurality of protrusions are the same as the shape and size of the second protrusion 132. Thus, after the plurality of protrusions are inserted into the corresponding first positioning holes 21 of the first substrate 20, the force applied to the first substrate 20 is substantially the same. However, it will be understood that in other embodiments, two or more first protrusions 131 may have inconsistent shapes and / or sizes; two or more second protrusions 132 may have inconsistent shapes and / or sizes; and / or, two or more first protrusions and second protrusions may have inconsistent shapes and / or sizes.

[0068] In some exemplary implementations, such as Figure 4 As shown. Each of the multiple protrusions is cylindrical. In some examples, the shape of each of the multiple protrusions can be other shapes. For example, the shape of each of the multiple protrusions can be a polygonal column.

[0069] In some exemplary implementations, such as Figure 1As shown, due to the weight of the conductive beam 13 itself, there is an angle between the second protrusion 132 of the conductive beam 13 and the conductive cover 12. When the conductive cover 12 and the conductive beam 13 rotate about the rotation axis 16 relative to the first support base 11 toward the second substrate 30, the second protrusion 132, the closest of the plurality of protrusions to the first support base 11, may first contact the first substrate 20. As the fastener 15 continues to be pressed toward the second support base 14, which is engaged to the second substrate 30, until the conductive cover 12 and the conductive beam 13 are parallel to the first substrate 20 and the first end 121 of the conductive cover 12 is engaged to the second support base 14 by the fastener 15, the second protrusion 132 remains in contact with the first substrate 20 throughout. Because the second protrusion 132 can be displaced relative to the conductive cover 12, particularly because the second protrusion 132 can be displaced relative to the conductive cover 12 about the connecting axis 18 (see... Figure 3 The second protrusion 132 rotates, therefore, there is no significant interaction force between it and the first substrate 20. The fastener 15 is then tightened so that the first protrusion 131 and the second protrusion 132 are inserted into a portion of the corresponding first positioning hole 21 in the first substrate 20. In this way, the conductive beam 13 is fixedly connected to the first protrusion 131 of the conductive cover 12 such that: during the rotation of the conductive cover 12 and the conductive beam 13 relative to the first support base 11 toward the second substrate 30 about the rotation axis 16, the second protrusion 132 of the conductive beam 13 near the first support base 11 can first contact the first substrate 20 and remain in contact thereafter, because the second protrusion 132 can be displaced relative to the conductive cover 12, particularly because the second protrusion 132 can be displaced relative to the conductive cover 12 about the connecting axis 18 (see... Figure 3 The second protrusion 132 rotates, so there is no large interaction force between the second protrusion 132 and the first substrate 20, thereby avoiding the problem of uneven force caused by the first protrusion 131 and the second protrusion 132 pressing into the corresponding first positioning hole 21 of the first substrate 20 one after the other.

[0070] With the locking member provided in this application, at least one first protrusion 131 of the plurality of protrusions of the conductive beam 13 is used as a fixing fulcrum because it is fixedly connected to the conductive cover 12. The second protrusion 132 can maintain contact with the first substrate 20 after contacting the first substrate 20 and can be displaced relative to the conductive cover 12. In particular, it can be displaced relative to the conductive cover 12 around the connecting shaft 18 (see...) Figure 3The rotation ensures that there is no significant interaction force between the second protrusion 132 and the first substrate 20. Therefore, the multiple protrusions of the conductive beam 13 work as a whole on a seesaw-like principle, thereby solving the problem of uneven force distribution on the first substrate 20 caused by the first and second protrusions pressing into the corresponding first positioning holes 21 of the first substrate 20 in sequence.

[0071] exist Figures 1 to 4 In the exemplary embodiments shown, particular reference is made to Figure 3 The conductive beam 13 has a first protrusion 131 and a second protrusion 132 protruding from its lower surface. The conductive beam 13 includes a pair of grooves 133 on its upper surface opposite to at least one first protrusion 131, and a spacer 134 between the pairs of grooves 133. The conductive cover 12 includes a pair of lugs 124 at positions corresponding to the pairs of grooves 133 of the conductive beam 13, with the pairs of lugs 124 spaced apart by a distance corresponding to the spacer 134. The pairs of lugs 124 are placed in the pairs of grooves 133, and the spacer 134 is placed between the pairs of lugs 124. The connecting shaft 18 extends through the holes of the pairs of lugs 124 and the holes of the spacer 134, thereby fixing at least one first protrusion 131 to the conductive cover 12.

[0072] In some exemplary implementations, such as Figure 4 As shown, at least one first protrusion 131 of the plurality of protrusions of the conductive beam 13 protrudes from the lower surface of the central portion of the conductive beam 13 in the length direction at a first side portion 135 in the width direction adjacent to the conductive beam 13, and a second protrusion 132 of the plurality of protrusions protrudes from the lower surface of the two ends of the conductive beam 13 in the length direction at a second side portion 136 opposite to the first side portion 135 of the conductive beam 13. Thus, when the first protrusion 131 and the second protrusion 132 of the plurality of protrusions are respectively inserted into the corresponding first positioning holes 21 in the first substrate 20 and further pressed toward the first substrate 20, the force exerted by the first protrusion 131 and the second protrusion 132 of the plurality of protrusions on the first substrate 20 forms a stable triangular structure on the first substrate 20, so as to securely mount the first substrate 20 to the second substrate 30.

[0073] In some exemplary embodiments, at least one first protrusion 131 of the conductive beam 13 may also be fixedly connected to the conductive cover 12 in other ways. For example, at least one first protrusion 131 of the conductive beam 13 may be screwed to the conductive cover 12 by means of screws.

[0074] In some exemplary embodiments, the fastener 15 may be a thumbscrew. Thus, the operator can engage the conductive cover 12 to the second support base 14 and / or the second substrate 30 simply by pressing the thumbscrew with their finger to rotate the conductive cover 12 about the rotation axis 16 relative to the first support base 11, thereby further mounting the first substrate 20 to the second substrate 30, without any additional tools. Furthermore, after positioning the plurality of protrusions of the conductive beam 13 in the corresponding first positioning holes 21 of the first substrate 20, the operator can adjust the force exerted by the plurality of protrusions on the first substrate by tightening the thumbscrew, thereby achieving a good installation effect.

[0075] Another aspect of this application provides an electronic system 100. (Refer to...) Figures 1 to 4 The electronic system 100 includes: a first substrate 20, which includes a plurality of first positioning holes 21; a second substrate 30, which includes a plurality of second positioning holes 33, with the first substrate 20 located above the second substrate 30; a connector 40 disposed between the first substrate 20 and the second substrate 30, the connector 40 connecting the first substrate 20 and the second substrate 30; and referenced above. Figures 1 to 4 The locking member 10 is configured to mount the first substrate 20 to the second substrate 30 in a tool-free manner.

[0076] In some examples, the first substrate may be, for example, a System-on-Chip Advanced Memory Module (SOCAMM). However, this application is not limited to this. The second substrate may be, for example, a printed circuit board. However, this application is not limited to this. The connector may be an SOCAMM connector. The connector is configured to connect the two substrates, and the specific configuration of the connector may be as described in the previous U.S. application US20240178592A1. However, this application is not limited to this. Depending on the actual use of the product, the connector may have any other suitable structure, as long as it can connect the two substrates and meet the requirements for electrical and mechanical reliability.

[0077] In some exemplary implementations, such as Figure 1 and Figure 2 As shown, the connector 40 includes a plurality of upper protrusions 41 and a plurality of lower protrusions 42 protruding from the upper and lower surfaces of the connector, respectively. The upper protrusions 41 are inserted into a portion of a corresponding first positioning hole 21 of the first substrate 20, and the lower protrusions 42 are inserted into a corresponding second positioning hole 33 of the second substrate 30, thereby connecting the first substrate 20 to the second substrate 30 and forming a reliable mechanical and electrical connection between the first substrate 20 and the second substrate 30.

[0078] In some exemplary implementations, such as Figure 1 As shown, a backplate 32 with a shielding device 31 is attached to the lower surface of the second substrate 30. The shielding device is used to prevent light from inside the electronic device from leaking to the outside. In some exemplary embodiments, the shielding device is a Mylar sheet. In some exemplary embodiments, the Mylar sheet is formed of polycarbonate film or polyethylene terephthalate (PET) film. In some examples, the Mylar sheet has the characteristics of dimensional stability and tear resistance. Therefore, in some exemplary embodiments of this application, the Mylar sheet will not easily deform during assembly. In some exemplary embodiments, the Mylar sheet can be directly attached to the lower surface of the second substrate due to its own adhesiveness. Therefore, no other adhesive is needed during the assembly of the Mylar sheet to the second substrate, thereby shortening the assembly time.

[0079] According to the electronic system 100 provided in this application, the first support base 11 and the second support base 14 of the locking member 10 are engaged to the upper surface of the second substrate 30 in the longitudinal direction and are positioned adjacent to the two ends of the first substrate 20 in the longitudinal direction. When the fastener 15, which extends through the connection hole 123 of the first end 121 of the conductive cover 12, is pressed toward the second support base 14, the second end 122 of the conductive cover 12 rotates about the rotation axis 16 relative to the first support base 11 until the first end 121 of the conductive cover 12 is connected to the second support base 14 by the fastener 15, the fastener 15 is tightened such that the first protrusion 131 and the second protrusion 132 of the plurality of protrusions of the conductive beam 13 are inserted into a portion of the corresponding first positioning hole 21 of the first substrate 20. Thus, by pressing the first end 121 of the conductive cover 12 with the fastener 15, the conductive cover 12 rotates relative to the first support base 11 about the rotation axis 16. The locking member 10 utilizes the lever principle of the conductive cover 12 to reduce the force applied to the conductive cover 12, thereby improving work efficiency. Furthermore, without the use of additional tools, the operator only needs to operate the fastener of the locking member 10 to securely connect and install the first substrate 20 to the second substrate 30.

[0080] Another aspect of this application provides a locking member 10, referring to... Figures 5 to 9 The locking member 10 is configured to mount the first substrate 20 to the second substrate 30 in a tool-free manner. The locking member 10 includes: a locator 101 configured to engage with the second substrate 30; a pawl 102 configured to engage with the first substrate 20; and an elastic member 103 configured to engage the pawl 102 with the locator 101.

[0081] In some exemplary implementations, such as Figure 5 and Figure 6 As shown, a heat sink 50 is mounted on the first substrate 20 to dissipate heat from the first substrate 20 and / or the second substrate 30. Thus, in Figure 5 and Figure 6 In the exemplary embodiment shown, the pawl 102 is configured to engage with the heat sink 50. That is, the pawl 102 is configured to engage indirectly with the first substrate 20. However, this application is not limited thereto, and in some examples, the pawl 102 may be configured to engage directly with the first substrate 20. In some examples, the elastic member 103 may be a spring, such as a coil spring. However, this application is not limited thereto. In some examples, the elastic member 103 may be a resilient rubber element.

[0082] In some exemplary implementations, such as Figures 7 to 9 As shown, the locking member 10 also includes a fastener 15, which includes a head 151 and a shank 152. The head 151 engages with a pawl 102, and the shank 152 extends through the pawl 102, the elastic member 103, and the positioner 101. The distal portion 1521 of the shank 152 is threaded, and at least a portion of the threaded distal portion 1521 is fastened to a corresponding threaded hole in the second base plate 30 during use.

[0083] In some exemplary embodiments, after the pawl 102 is rotated toward the first substrate 20 and / or the heat sink 50 and positioned above the first substrate 20 or the heat sink 50, the fastener 15 is tightened so that the pawl 102 engages with the first substrate 20 or the heat sink 50, and the first substrate 20 is pressed toward the second substrate 30 by the fastener 15, thereby mounting the first substrate 20 to the second substrate 30.

[0084] In some exemplary implementations, such as Figure 5 and Figure 6 As shown, the locator 101 is configured to engage with the second substrate 30 in such a way that it is positioned adjacent to the end of the first substrate 20 in the length direction of the second substrate 30. In some exemplary embodiments, such as Figures 7 to 9 As shown, the positioner 101 includes a first end 1011 and a second end 1012 opposite in the axial direction. The first end 1011 includes a plurality of protrusions 1013, which are inserted into corresponding holes in the second substrate 30, thereby engaging the positioner 101 to the second substrate 30. However, this application is not limited thereto. In some examples, the positioner 101 may be engaged to the second substrate 30 in other ways. For example, the positioner 101 may be soldered to the second substrate 30.

[0085] In some exemplary implementations, such as Figure 7 As shown, the positioner 101 includes a hollow portion 1014, and the first end 1011 of the positioner 101 includes a seat portion 1015. An elastic member 103 is arranged in the hollow portion 1014 on the seat portion 1015, and a pawl 102 is arranged on the elastic member 103 and abuts against the elastic member 103, thereby connecting the pawl 102 to the positioner 101.

[0086] In some exemplary implementations, such as Figure 7 As shown, the pawl 102 includes a curved first portion 1021 and a linearly extending second portion 1022. The first portion 1021 is formed into a generally L-shaped form including a long side portion 10211 and a short side portion 10212. The second portion 1022 extends from the long side portion 10211 of the first portion 1021 into the hollow portion 1014 of the locator 101 to abut against the elastic member 103. The short side portion 10212 of the first portion 1021 is configured to engage with the first substrate 20 or the heat sink 50.

[0087] In some exemplary embodiments, after the pawl 102 is rotated toward the first substrate 20 and / or the heat sink 50 and positioned above the first substrate 20 or the heat sink 50, the fastener 15 is tightened so that the second portion 1022 of the pawl 102 is pressed toward the second substrate 30 against the elastic force of the elastic member 103, thereby reducing the distance H1 between the lower edge of the long side portion 10211 of the first portion 1021 of the pawl 102 and the second end 1012 of the locator (see...). Figure 8 The distance H2 between the short side portion 10212 of the first portion 1021 of the pawl 102 and the second substrate 30 (see...) Figure 7 Adjustments can be made accordingly.

[0088] In some examples, when a heat sink 50 is mounted on the first substrate 20, the head 151 of the fastener 15 is turned slightly to simultaneously adjust both distances H1 and H2, thereby allowing the short side portion 10212 of the first portion 1021 of the pawl to engage with the heat sink 50. When a heat sink 50 is not mounted on the first substrate 20, the head 151 of the fastener 15 is turned more significantly to simultaneously adjust both distances H1 and H2, thereby allowing the short side portion 10212 of the first portion 1021 of the pawl to directly engage with the first substrate 20. In this way, the operator can easily adjust the component to be engaged by the pawl 102 according to the needs of the product to adapt to different installation requirements.

[0089] In some exemplary implementations, such as Figure 8As shown, the second end 1012 of the locator 101 includes circumferentially opposite locating grooves 1016, one of which faces one end of the first substrate 20 in the longitudinal direction during use; the second portion 1022 of the pawl 102 includes opposing bosses 1023 projecting radially, one of which faces the aforementioned end of the first substrate 20 in the longitudinal direction during use; after the pawl 102 is rotated toward the first substrate 20 and / or the heat sink 50 and positioned above the first substrate 20 or the heat sink 50 and the fastener 15 is tightened, the bosses 1023 are inserted into the locating grooves 1016. In this way, precise positioning of the pawl 102 relative to the locator 101 is provided, thereby making the operation of the locking member more precise.

[0090] In some exemplary implementations, such as Figure 9 The second end 1012 of the positioner 101 further includes a protrusion 1017 adjacent to the positioning groove in the positioning groove 1016 that faces the first substrate 20 during use. The protrusion 1017 protrudes toward the pawl 102. When the pawl 102 is rotated toward the first substrate 20 and / or the heat sink 50 and positioned above the first substrate 20 or the heat sink 50, the boss in the boss 1023 of the pawl 102 that faces the first substrate 20 contacts the protrusion 1017, thereby restricting further rotation of the pawl 102.

[0091] exist Figures 5 to 9 In the exemplary embodiment shown, the fastener 15 may be a thumb screw. Thus, the operator only needs to rotate the pawl 102 toward the first substrate 20 and / or the heat sink 50, and then tighten the head of the thumb screw to engage the pawl 102 with the first substrate 20 and / or the heat sink 50, thereby mounting the first substrate 20 to the second substrate 30 without any other additional tools.

[0092] Another aspect of this application provides an electronic system 100. The electronic system 100 includes: a first substrate 20, the first substrate 20 including a plurality of first positioning holes 21; a second substrate 30, the second substrate 30 including a plurality of second positioning holes 33, the first substrate 20 being located above the second substrate 30; a connector 40 disposed between the first substrate 20 and the second substrate 30, the connector 40 connecting the first substrate 20 and the second substrate 30, and referenced above. Figures 4 to 9 The locking member 10 is configured to mount the first substrate 20 to the second substrate 30 in a tool-free manner.

[0093] In some examples, the first substrate may be, for example, a System-On-Chip Attached Memory Module (SOCAMM). However, this application is not limited to this. The second substrate may be, for example, a printed circuit board. However, this application is not limited to this. The connector may be an SOCAMM connector. The connector is configured to connect the two substrates, and the specific configuration of the connector may be as described in the previous U.S. application US20240178592A1. However, this application is not limited to this. Depending on the actual use of the product, the connector may have any other suitable structure, as long as it can connect the two substrates and meet the requirements for electrical and mechanical reliability.

[0094] In some exemplary embodiments, a backplate 32 with a shielding device 31 is attached to the lower surface of the second substrate 30. The shielding device is used to prevent light from inside the electronic device from leaking to the outside. In some exemplary embodiments, the shielding device is a Mylar sheet. In some exemplary embodiments, the Mylar sheet is formed of polycarbonate film or polyethylene terephthalate (PET) film. In some examples, the Mylar sheet has the characteristics of dimensional stability and tear resistance. Therefore, in some exemplary embodiments of this application, the Mylar sheet will not easily deform during assembly. In some exemplary embodiments, the Mylar sheet can be directly attached to the lower surface of the second substrate due to its own adhesiveness. Therefore, no other adhesives are needed during the assembly of the Mylar sheet to the second substrate, thereby shortening the assembly time.

[0095] In some exemplary embodiments, the connector 40 includes a plurality of upper protrusions 41 and a plurality of lower protrusions 42 protruding from the upper and lower surfaces of the connector, respectively. The upper protrusions 41 are inserted into a portion of a corresponding first positioning hole 21 of the first substrate 20, and the lower protrusions 42 are inserted into a corresponding second positioning hole 33 of the second substrate 30, thereby connecting the first substrate 20 to the second substrate 30 and forming a reliable mechanical and electrical connection between the first substrate 20 and the second substrate 30.

[0096] In some exemplary implementations, such as Figure 5 and Figure 6As shown, the locator 101 of the locking member 10 is engaged with the upper surface of the second substrate 30 in a manner that positions it adjacent to the end of the first substrate 20 along the length of the second substrate 30. A heat sink 50 is disposed on the first substrate 20, and a thermal pad 60 is disposed between the heat sink 50 and the first substrate 20 to connect the heat sink 50 and the first substrate 20, thereby further improving heat dissipation. The lower surface of the heat sink 50 includes a plurality of protrusions that insert into portions of corresponding first positioning holes 21 in the first substrate 20. After the pawl 102 is rotated toward and / or positioned above the first substrate 20 and / or the heat sink 50, the fastener 15 is tightened, causing the pawl 102 to engage with the first substrate 20 or the heat sink 50, thereby connecting and mounting the first substrate 20 to the second substrate 30. Thus, without the need for additional tools, the operator can securely connect and install the first substrate 20 to the second substrate 30 simply by operating the fastener 15 and pawl 102 of the locking member 10.
