Description
Technical Field
[0001] This application relates to connection structures for electronic devices, and more particularly to a connection structure and an electronic device. Background Technology
[0002] In mechanical connection operations, threaded connection structures are commonly used, for example, in mechanical assembly, equipment manufacturing, and routine installation. However, in related technologies, the screw with external threads is designed separately from the component with threaded holes, making the screw easy to lose. Moreover, threaded connection structures have limitations in practical applications. For example, in dimly lit or confined spaces such as the installation inside electronic equipment or the maintenance of underground pipelines, it is difficult to quickly align the screw and the threaded hole, requiring repeated adjustments, which reduces installation efficiency and may even lead to thread wear, weakening the strength of the threaded connection.
[0003] To address the aforementioned issues, the relevant technologies urgently need improvement. Utility Model Content
[0004] This application provides a connection structure and an electronic device to at least solve the aforementioned problems in the related art.
[0005] To achieve the above objectives, this application provides the following technical solution: a connection structure, the connection structure comprising:
[0006] A connector has a connecting hole, which includes a first segment group, a second segment group, and a third segment group. The first segment group is located in the bottom region of the connecting hole, the third segment group is located in the port region of the connecting hole, and the second segment group is located between the first segment group and the third segment group. The first segment group has an internal thread.
[0007] The locking component has a connecting portion at its first end, and the connecting portion is provided with external threads; wherein...
[0008] The outer diameter of the thread of the connecting part is smaller than the hole diameter of the second section group and larger than the hole diameter of the third section group. The connecting part is located inside the second section group. In the connected state, the external thread of the connecting part is connected to the internal thread of the first section group.
[0009] In some alternative embodiments, the connector has a notch at one end near the third segment group, the notch extending along the axial direction of the connecting hole to the second segment group, and the notch communicating with the third segment group and the second segment group.
[0010] In the loosened state, the locking member is inclined relative to the central axis of the connecting hole and passes through the notch, with the second end of the locking member offset from the central axis of the connecting hole.
[0011] In some alternative embodiments, the locking member is further provided with a smooth rod section in the middle, and the smooth rod section is slidably clearance-fitted with the hole wall of the third segment group.
[0012] In some alternative implementations, the connector includes a first connector and a second connector;
[0013] The first connector is connected to the second connector, the third segment group and the second segment group are located on the first connector, and the first segment group is located on the second connector.
[0014] In some alternative embodiments, the connector further includes a support body with a through hole, and the first connector is connected to the second connector through the support body;
[0015] The first connector is embedded at one end of the through hole, and the second connector is embedded at the other end of the through hole.
[0016] In some alternative embodiments, the supporting body carries a locking component on the side facing the first connector, the locking component including a head, the head forming a second end of the locking component;
[0017] In the connected state, the external thread of the connecting part is connected to the internal thread of the first segment group, and the head can press against the component to be locked so that the component to be locked is fixed to the bearing body.
[0018] In some alternative implementations, the head is also provided with a slot or cross slot for external screwdrivers to tighten and lock the parts.
[0019] In some alternative embodiments, the connector further includes a first stop body, which is circumferentially disposed on the outer peripheral wall of the first connector body and abuts against the side of the bearing body facing the first connector body.
[0020] In some alternative embodiments, the connector further includes a second stop body, which is circumferentially disposed on the outer peripheral wall of the second connector body and abuts against the side of the bearing body facing the second connector body.
[0021] In some alternative embodiments, this application also includes an electronic device that includes the connection structure described above.
[0022] In the aforementioned connection structure, the connecting hole on the connector is designed as a three-section structure. This allows the connecting part of the locking component to be fully positioned in the second section group in the initial state. Because the diameter of the third section group is smaller than the outer diameter of the connecting part, the locking component is confined within the connecting hole and cannot disengage. When locking is required, the operator only needs to push the locking component so that its connecting part contacts the first section group, and then rotate it to complete the threaded engagement. The transition space provided by the second section group allows the connecting part to quickly slide into the first section group, solving the problem of alignment difficulties in narrow spaces and improving installation efficiency. Thus, in the loosened state, the locking component is confined within the connecting hole, preventing separation of the locking component from the connector and avoiding the risk of loss. In the connected state, quick locking via threads further improves the installation efficiency of the connection structure.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0034] In related technologies, threaded connections typically employ a separate screw and threaded hole design. Because the screw and connector are independent, they are prone to falling off or being lost during transportation or storage. In scenarios involving underground pipeline maintenance or internal assembly of electronic equipment, where the workspace is narrow and poorly lit, operators often struggle to quickly and accurately align the screw and threaded hole, requiring multiple attempts to complete the installation. This results in wasted time and wear on the threaded surfaces, increasing the risk of loosening over time.
[0035] To address the aforementioned issues, it is first necessary to resolve the risk of component loss due to the split structure, and secondly, to eliminate alignment obstacles between the threaded holes and screws. Based on this, a three-section structure for the connecting hole is designed, using port limits to prevent detachment and utilizing the transition space in the central area to achieve self-positioning.
[0036] Figure 1 This is a structural diagram of the connection structure; Figure 2 This is a structural diagram of the connector and locking components, combined with... Figure 1 and Figure 2In some embodiments, this application provides a connection structure including a connector 11 and a locking member 12. The connector 11 has a connection hole 111, which includes a first segment group 1111, a second segment group 1112, and a third segment group 1113. The second segment group 1112 is located between the first segment group 1111 and the third segment group 1113. The first segment group 1111 has an internal thread. The first end of the locking member 12 is provided with a connecting portion 121, which has an external thread. The outer diameter of the connecting portion 121 is smaller than the hole diameter of the second segment group 1112 and larger than the hole diameter of the third segment group 1113. In the loosened state, the connecting portion 121 is located inside the second segment group 1112. In the connected state, the external thread of the connecting portion 121 is connected to the internal thread of the first segment group 1111.
[0037] In the aforementioned connection structure, the connecting hole 111 on the connector 11 is designed as a three-section structure. This allows the connecting portion 121 of the locking member 12 to be fully positioned within the second section group 1112 in the initial state. Since the diameter of the third section group 1113 is smaller than the outer diameter of the connecting portion 121, the locking member 12 is confined within the connecting hole 111 and cannot disengage. When locking is required, the operator simply pushes the locking member 12 so that its connecting portion 121 contacts the first section group 1111, and then rotates it to complete the thread engagement. The transition space provided by the second section group 1112 allows the connecting portion 121 to quickly slide into the first section group 1111, solving the problem of alignment difficulties in narrow spaces and improving installation efficiency. Thus, in the detached state, the locking member 12 is confined within the connecting hole 111, preventing separation of the locking member 12 from the connector 11 and avoiding the risk of loss. In the connected state, it is quickly locked by the thread, thereby improving the installation efficiency of the connection structure.
[0038] Figure 3 This is an exploded structural diagram of the connectors and locking components, combined with... Figure 3 In some embodiments, the connecting hole 111 further includes a notch 1114, which is located at one end of the connector 11 near the third segment group 1113. The notch 1114 extends along the axial direction of the connecting hole 111 to the second segment group 1112, and communicates with both the third segment group 1113 and the second segment group 1112. In the loosened state, the locking member 12 is inclined relative to the central axis of the connecting hole 111 and passes through the notch 1114. The second end of the locking member 12 is offset from the central axis of the connecting hole 111.
[0039] Thus, when the connector 11 is in its initial un-screwed state, the outer diameter of its connecting part 121 is smaller than the diameter of the second segment group 1112, allowing it to tilt freely. At this time, the smooth rod section 122 of the connector 11 can be tilted within the notch groove 1114, and the head 123 of the connector 11 is horizontally away from the component to be locked 13, so as to provide a larger space for the component to be locked 13 to be installed or removed, thereby improving the convenience of installation. During the connection operation, when a pushing force is applied to the connector 11, the notch groove 1114 can guide the connector 11 to adjust its angle until the connecting part 121 of the connector 11 and the internal thread of the first segment group 1111 form a coaxial alignment, eliminating the uncertainty of manual alignment, significantly improving the alignment efficiency of threaded connections in a narrow space, and effectively reducing thread wear.
[0040] It should be noted that the notch 1114 extends along the axial direction of the connecting hole 111 to the second segment group 1112, meaning that the notch 1114 can extend to the junction of the second segment group 1112 and the third segment group 1113; the notch 1114 can also extend to the middle region of the second segment group 1112.
[0041] Combination Figure 3 In some embodiments, the middle part of the locking member 12 is further provided with a smooth rod section 122, which is slidably clearance-fitted with the hole wall of the third segment group 1113, so that the connecting part 121 of the locking member 12 can be quickly aligned with the first segment group 1111 through the hole wall of the third segment group 1113, thereby improving the connection efficiency of the locking member 12.
[0042] Combination Figure 3 In some embodiments, the connector 11 includes a first connector 112 and a second connector 113; the first connector 112 is connected to the second connector 113, the third segment group 1113 and the second segment group 1112 are disposed on the first connector 112, and the first segment group 1111 is disposed on the second connector 113.
[0043] Thus, both the first connector 112 and the second connector 113 are independent components, so that the connector 11 forms a split structure. This facilitates modular production of the connector 11 and reduces the processing difficulty of the connecting hole 111. At the same time, the split structure of the connector 11 makes the selection of materials for the first connector 11 and the second connector 11 more flexible. For example, the first connector 112 can be made of plastic, and the second connector 113 can be made of metal such as steel or aluminum alloy. This reduces the processing difficulty of the third segment 1113 and the second segment 1112, and the strength of the internal thread of the first segment 1111 can be guaranteed by the metal material, thereby improving the connection reliability of the connector 11.
[0044] Preferably, the first connector 112 is made of plastic and the second connector 113 is made of metal.
[0045] Combination Figure 1 and Figure 2 In some embodiments, the connector 11 further includes a support body 116 with a through hole, and the first connector 112 is connected to the second connector 113 through the support body 116; the first connector 112 is embedded at one end of the through hole, and the second connector 113 is embedded at the other end of the through hole. For example, the support body 116 can be a circuit board.
[0046] Thus, by embedding the first connector 112 and the second connector 113 at opposite ends of the through hole, the axial guiding function of the through hole can be used to solve the positioning problem during the assembly of the first connector 112 and the second connector 113, so as to ensure that the two can be quickly and accurately aligned, thereby improving the installation efficiency between the first connector 112, the second connector 113 and the supporting body 116.
[0047] It is understood that the connection between the first connector 112 and the second connector 113 via the supporting body 116 means that both the first connector 112 and the second connector 113 are connected to the supporting body 116, thereby realizing the relationship between the first connector 112 and the second connector 113. The first connector 112 and the second connector 113 can have a direct fixed connection to form an integral structure, or they can be spaced apart or abutted against each other, without a direct fixed connection, to form a separate structure.
[0048] Furthermore, the first connector 112 can be partially or fully embedded in the through hole; the second connector 113 can be partially or fully embedded in the through hole; the first connector 112 and the second connector 113 can be connected to the through hole by means of interference fit, snap-fit, bonding or welding.
[0049] In some optional embodiments, the connecting hole can be directly formed on the supporting body 116. In this case, the through hole is the connecting hole, and the through hole includes a first segment group 1111, a second segment group 1112 and a third segment group 1113.
[0050] Combination Figure 1 and Figure 3In some embodiments, the supporting body 116 carries a locking component 13 on the side facing the first connector 112. The locking component 13 can be locked and fixed by the connection structure described in this application. The locking component 12 includes a head 123, which forms the second end of the locking component 12. In the connected state, the external thread of the connecting portion 121 is connected to the internal thread of the first segment group 1111, and the head 123 can abut against the locking component 13 to fix the locking component 13 to the supporting body 116. For example, the locking component 13 can be a wireless network card or a solid-state drive.
[0051] Thus, when an external force, such as the rotational force generated by manually tightening a screwdriver, is applied to the locking member 12, the head 123 of the locking member 12 is displaced along the axial direction of the through hole as the connecting part 121 is screwed in. Since the component to be locked 13 is pre-positioned on the supporting body 116, the head 123 can move axially to press the component to be locked 13, thereby achieving a fixed connection between the component to be locked 13 and the supporting body 116.
[0052] In some embodiments, the head 123 is further provided with a slotted or Phillips head for an external screwdriver to tighten and lock the attachment 12. Thus, by introducing a standardized slotted or Phillips head structure, the time required for the screwdriver to find the point of application of force during assembly is reduced.
[0053] Combination Figure 3 In some embodiments, the connector 11 further includes a first stop 114, which is arranged around the outer peripheral wall of the first connector 112 and abuts against the side of the bearing body 116 facing the first connector 112.
[0054] Thus, when the first connector 112 is installed into the through hole, the first stop 114 contacts one end face of the supporting body 116, which completely restricts the displacement of the first connector 112 in the axial direction of the through hole, so as to automatically adjust the depth of the first connector 112 embedded in the through hole, thereby realizing the positioning of the first connector 112. Moreover, it also makes the installation of the first connector 112 more convenient and quick, saving time and effort.
[0055] Combination Figure 3 In some embodiments, the connector 11 further includes a second stop 115, which is circumferentially disposed on the outer peripheral wall of the second connector 113 and abuts against the side of the bearing body 116 facing the second connector 113.
[0056] Thus, when the second connector 113 is installed into the through hole, the second stop contacts the end face on the other side of the supporting body 116, so that the displacement of the second connector 113 in the axial direction of the through hole is completely restricted, so as to automatically adjust the depth of the second connector 113 embedded in the through hole, thereby realizing the positioning of the second connector 113. Moreover, it also makes the installation of the second connector 113 more convenient and quick, saving time and effort.
[0057] In some embodiments, this application also describes an electronic device, which includes the aforementioned connection structure and a component to be locked. The electronic device can lock and fix the component to be locked 13 through the connection structure. The connector 11 has a connection hole 111, which includes a first segment group 1111, a second segment group 1112, and a third segment group 1113. The first segment group 1111 has an internal thread, and the second segment group 1112 is located between the first segment group 1111 and the third segment group 1113. The locking component 12 has a connecting portion 121 at its first end. The outer diameter of the connecting portion 121 is smaller than the hole diameter of the second segment group 1112 and larger than the hole diameter of the third segment group 1113. In the initial state, the connecting portion 121 is located inside the second segment group 1112. In the connected state, the external thread of the connecting portion 121 engages with the internal thread of the first segment group 1111. Exemplarily, the electronic device can be a laptop or a desktop computer.
[0058] Thus, in the initial state, the connecting portion 121 of the locking member 12 is confined within the connecting hole 111, preventing separation from the connecting member 11. During installation, the locking member 12 moves along the second segment group 1112 towards the first segment group 1111, and the external thread automatically engages with the internal thread without manual alignment. The limiting effect of the bore diameter of the third segment group 1113 prevents the connecting portion 121 from accidentally disengaging when not in use. The space of the second segment group 1112 allows the connecting portion 121 to freely adjust its angle in the initial position, providing more installation space for the component 13 to be locked, thus improving the ease of installation of the component 13 to be locked.
[0059] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
