Description

Technical Field

[0001] This application relates to the manufacture and assembly of electronic devices, and in particular to an interface fine-tuning device and an electronic device. Background Technology

[0002] In the manufacturing and assembly process of electronic devices, connector modules containing interfaces (such as USB interfaces) are typically fixed to the device housing, and their electrical pins are soldered or connected to the main circuit board (PCB) inside the device. However, due to manufacturing tolerances or assembly errors in components such as the device housing, connector modules, and internal circuit boards, misalignment often occurs between the opening position of the USB interface on the housing and the pad position on the internal circuit board. This misalignment can cause stress between the connector pins and the circuit board pads, leading to problems such as cold solder joints, poor contact, or even breakage after long-term use. This affects the device's charging and data transmission functions, reducing product reliability and lifespan.

[0003] Therefore, how to easily fine-tune the position of the interface after the product is assembled to accommodate the offset caused by manufacturing tolerances and avoid defective products and scrap losses caused by interface position offset is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an interface fine-tuning device and electronic device capable of compensating for positional deviations between the housing opening and the internal circuit board pads.

[0005] Firstly, embodiments of this application provide an interface fine-tuning device.

[0006] An interface fine-tuning device according to an embodiment of this application includes: an interface frame; an interface module slidably disposed within the interface frame, the front end of the interface module having a plug-in interface for external connector insertion, the plug-in interface having at least one connection terminal; the rear end of the interface module having an electrical connection portion having a plurality of connection contacts, the connection contacts corresponding one-to-one with the connection terminal and electrically connected; a docking module fixedly connected to the interface frame, the docking module having a plurality of conductive tracks along a first direction, each conductive track being electrically connected to a corresponding line in a circuit board of an external electronic device, the conductive track corresponding one-to-one with the connection contacts, the connection contacts being elastically slidably connected to the corresponding conductive track; and an adjustment component connected to the interface frame, the adjustment component being used to drive the interface module to slide along the first direction within the interface frame and fix the position of the interface module after sliding.

[0007] The interface fine-tuning device according to the embodiments of this application has at least the following beneficial effects: The interface fine-tuning device achieves adjustable electrical connection between the interface module and the circuit board by slidably arranging the interface module within the interface frame and providing a contact point at its rear electrical connection portion that is elastically slidably connected to the conductive track on the docking module. When the interface module needs to be adjusted due to installation errors, the adjustment component can drive the interface module to slide within the interface frame along a first direction. During the sliding process, since the contact point and the conductive track are elastically slidably connected, they always maintain effective electrical contact, thereby ensuring stable signal and / or power transmission. After adjusting to a suitable position, the adjustment component can also fix the interface module to prevent subsequent displacement. This structure allows for precise adjustment of the interface position during assembly, effectively compensating for positional deviations between the housing opening and the internal circuit board pads, avoiding assembly stress caused by rigid connections, thereby significantly improving connection reliability and product durability, and also increasing the yield rate of production assembly.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0025] In a first aspect, embodiments of this application provide an interface fine-tuning device to solve the problem of misalignment between the interface and the housing hole position in electronic devices due to assembly errors.

[0026] like Figure 1 As shown, the interface fine-tuning device in the embodiment includes: an interface frame 100, an interface module 200 slidably disposed within the interface frame 100, a docking module fixedly connected to the interface frame 100, and an adjustment component for driving the interface module 200 to slide.

[0027] The interface frame 100 (provides a basic support structure for the entire device; it can be a frame made of materials such as metal or plastic) is used to accommodate and limit the movement of the interface module 200.

[0028] The interface module 200 is the core component for direct connection with external connectors. It is slidably mounted inside the interface frame 100. The front end of the interface module 200 has a connector for insertion into an external connector. In this embodiment, the connector can be a USB Type-C female connector, but it can also be other types of interfaces, such as HDMI or DisplayPort. The connector has at least one connection terminal for physical and electrical connection with the corresponding terminal of the inserted external connector. The rear end of the interface module 200 has an electrical connection section. This electrical connection section has several contact points 210, which correspond one-to-one with and are electrically connected to the connection terminal within the connector. The function of the contact points 210 is to guide electrical signals or power from the external connector from the connection terminal and transmit them to the docking module at the rear end. In this embodiment, the contact points 210 can be conductive probes with a certain degree of elasticity to ensure reliable electrical contact with the docking module during sliding. Of course, the contact point 210 can also be other structures, such as a spring, a conductive brush, or a metal claw, as long as it can achieve an elastic sliding electrical connection.

[0029] The docking module is a crucial bridge connecting the interface module 200 and the internal circuitry of the electronic device. It is fixedly connected to the interface frame 100. The docking module has several conductive tracks arranged along a first direction (i.e., the sliding direction of the interface module 200, typically perpendicular to the insertion / removal direction of the interface). Each conductive track is electrically connected to a corresponding line on the circuit board, thereby introducing signals and power into the main system of the device. These conductive tracks correspond one-to-one with the connection contacts 210 at the rear end of the interface module 200. When the interface module 200 slides, its connection contacts 210 elastically slide along the corresponding conductive track, maintaining electrical connection at all times. This design allows the interface module 200 to be freely fine-tuned within a certain range without interrupting the electrical path with the main circuit board. The conductive tracks can be printed on a circuit board (such as a PCB) as strip pads 410, or as independent metal strips, conductive coatings, etc.

[0030] The adjustment component is used to precisely adjust and fix the position of the interface module 200. It is connected to the interface frame 100 and can drive the interface module 200 to slide within the interface frame 100 along a preset first direction. After adjusting to the optimal position (i.e., the position with the most stable insertion and optimal contact), the adjustment component can also fix the interface module 200 in that position to prevent it from moving due to vibration or external force.

[0031] Understandably, to ensure that the interface module 200 moves smoothly and precisely linearly along a preset first direction during adjustment, avoiding deflection, tilting, or wobbling, and thus ensuring that all rear-end contact points 210 can slide synchronously with their corresponding conductive tracks and maintain good contact, in some embodiments, at least one guide member is provided inside the interface frame 100 along the first direction. Correspondingly, the interface module 200 has a matching structure, enabling it to slide with the guide member. The core function of this guide member is to constrain the movement trajectory of the interface module 200, limiting its degrees of freedom to translation along the first direction, thereby eliminating the possibility of movement in other directions (such as up-and-down, left-and-right swaying, or rotation around an axis). The guide can be implemented in various ways. For example, it can use a slide rail and a slider in combination. One or more guide grooves (slide rails) can be machined on the inner wall of the interface frame 100, and corresponding protrusions (sliders) can be set on the outer wall of the interface module 200, so that the slider can slide in the slide rail. It can also use a guide post and a guide hole in combination. One or more guide posts can be fixed on the interface frame 100, and corresponding guide holes can be opened on the interface module 200. The guide post passes through the guide hole to guide the movement of the interface module 200. It can also use a cross-sectional fit. The inner cavity of the interface frame 100 and the outer shape of the interface module 200 can be designed to match the cross-sectional shape, such as square, rectangular or polygonal. The fit between the surfaces can be used to prevent the module from rotating and achieve the guiding function.

[0032] Optionally, in a simple, low-cost, and easy-to-implement embodiment, the guide element may specifically be one or more slide bars 110. For example... Figure 1 As shown, four sliding rods 110 are provided, with both ends of these rods 110 fixedly connected to the interface frame 100, forming a stable guide rail. The interface module 200 has corresponding through holes, allowing the sliding rods 110 to slide slidably through it. When the adjusting component drives the interface module 200 to move, the interface module 200 will precisely reciprocate linearly along these fixed sliding rods 110. This "rod-hole" sliding fit structure is not only simple to manufacture and assemble, but also provides a very stable and reliable guiding effect.

[0033] Furthermore, considering the intricate internal structure of the front-end connector (such as a USB Type-C female connector) of the interface module 200, and the fact that the connection terminals are the core of the electrical functions, the layout of the guide (slide bar 110) is optimized in some embodiments to avoid any potential physical damage or signal interference to these sensitive components. For example, the slide bar 110 is positioned near the rear end of the interface module 200, away from the connector. Simultaneously, the installation position and path of the slide bar 110 are specially designed to ensure that it does not come into contact with any connection terminals inside the connector. Four slide bars 110 are distributed in the rear half of the interface module 200, completely avoiding the front-end Type-C female connector area. This design physically isolates the guiding mechanical structure from the core electrical connection parts, ensuring that the guide performs its guiding function without adversely affecting the electrical performance and structural integrity of the interface.

[0034] To achieve the functionality of the docking module, some embodiments use a solution based on printed circuit board (PCB) technology. For example... Figure 2 As shown, the docking module can specifically be a docking circuit board 400. Correspondingly, the conductive tracks of the docking module can be specifically represented as several strip-shaped pads 410 fabricated on the docking circuit board 400. For example... Figure 2 As shown, these strip pads 410 are conductive metal strips (typically copper foil) printed or etched onto the surface of the mating circuit board 400, extending along a first direction (i.e., the sliding direction of the interface module 200). Each strip pad 410 has a specific length to ensure that the connection contact 210 at its rear end remains in contact with the corresponding strip pad 410 throughout the entire sliding adjustment range of the interface module 200. These strip pads 410 not only serve as physical tracks for the sliding of the connection contact 210, but more importantly, they are part of the electrical path. The back of the mating circuit board 400 has pads for connection to the circuit board. The mating circuit board 400 electrically connects each strip pad 410 to the corresponding pad on the back through its internal wiring (e.g., vias and wires). During assembly, these pads on the back of the mating circuit board 400 are securely electrically connected to the corresponding lines (signal lines, power lines, ground lines, etc.) on the circuit board by means of soldering or other methods. In this way, after the signal and / or power from the external connector is transmitted through the "connection terminal -> connection contact 210" of the interface module 200, the connection contact 210 makes sliding contact with the strip pad 410 (conductive track), and the current flows through the strip pad 410, and then through the circuit inside the mating circuit board 400, and finally to the circuit board, completing the construction of the entire electrical path.

[0035] In another embodiment, the docking module is specifically a spring-loaded assembly. This assembly mainly includes a spring-loaded base and several elastic contact pieces. The conductive track is no longer the fixed strip pad 410 described above, but is instead provided by these elastic contact pieces themselves. These elastic contact pieces are typically stamped from highly elastic and highly conductive metal materials such as phosphor bronze or beryllium copper. They are mounted on the spring-loaded base and arranged along a first direction (the sliding direction of the interface module 200). Each elastic contact piece corresponds to a connection contact point 210 at the rear end of the interface module 200. The connection contact point 210 of the interface module 200 abuts against the elastic contact piece to achieve electrical connection. When the interface module 200 slides, its connection contact point 210 slides across the surface of the elastic contact piece. Because the elastic contact piece itself is elastic, it applies a continuous and stable contact pressure to the connection contact point 210, which helps to form a more reliable electrical connection, especially in environments with minor vibrations. At this time, the connection point 210 on the interface module 200 can be rigid or it can be an elastic probe or gripper, forming a double elastic contact, which is more reliable.

[0036] Understandably, the function of the spring contact base is to fix and position all the elastic contact pieces and to be fixedly connected to the interface frame 100 as a whole. The structure of the spring contact base can be flexibly varied according to the specific needs of the product design. Several possible configurations are listed below. Insulating frame structure: The spring contact base can be a frame of insulating material (such as LCP, PBT and other engineering plastics) made by injection molding. The frame has corresponding slots or snap-fit ​​structures, and each metal elastic contact piece can be precisely embedded or snapped into it, thereby ensuring their position and spacing; the other end of the elastic contact piece is connected to the circuit board through welding, crimping, wires, etc. PCB substrate structure: The spring contact base can also be a printed circuit board. In this form, multiple independent elastic contact pieces are soldered onto this PCB substrate; the connection contacts 210 of the interface module 200 slide against these elastic contact pieces, and the current flows into the PCB substrate through the elastic contact pieces, and then connects to the pads on the back of the PCB substrate through the wiring on the PCB substrate, and finally connects to the circuit board. Metal plate and insulation structure: In some designs that require high-strength support, the spring plate base can be a metal plate with mounting holes formed by stamping; the elastic contact piece passes through these mounting holes but is isolated from the metal plate by insulating sleeves or insulating gaskets to prevent short circuits; the metal plate itself is responsible for providing strong mechanical support and is fixed to the equipment housing or mainboard.

[0037] In one embodiment, the adjusting assembly includes a resilient element 320 and a screw element 310. For example, ... Figure 1As shown, the elastic element 320 can be a compression spring, disposed between the interface frame 100 and the interface module 200. One end of the elastic element 320 abuts against the inner wall of the interface frame 100, and the other end abuts against the outer wall of the interface module 200. In the assembled state, the elastic element 320 is in a compressed state, thus generating a continuous elastic force. This elastic force acts as a driving force, constantly attempting to push the interface module 200 along a first direction. This driving force ensures that the interface module 200 does not swing freely within the frame and is always pushed to a limit position. The screw 310 is threadedly connected to the interface frame 100. This means that by rotating the screw 310, it can be screwed in or out relative to the interface frame 100. One end of the screw 310, such as its distal end, abuts against a surface of the interface module 200. The function of the screw 310 is to provide a pushing force opposite in direction to the driving force provided by the elastic element 320. For example, when the elastic element 320 pushes the interface module 200 backward, the screw 310 abuts against the interface module 200 from above or the side, and limits the final position of the interface module 200 by its axial position. When the user needs to fine-tune the position of the interface module 200, the screw 310 can be rotated with a tool (such as a screwdriver). When the screw 310 is screwed in, its end will move downward (or inward), thereby pushing the interface module 200 to overcome the elastic force of the elastic element 320. When the screw 310 is screwed out, its end will retract upward (or outward), reducing the pushing force on the interface module 200. Under the continuous driving force of the elastic element 320, the interface module 200 will automatically follow the movement of the screw 310. Once the desired position is achieved (e.g., when the connector and the opening of the housing are precisely aligned), the user can stop rotating the screw 310. Due to the self-locking characteristic of the threaded connection, the screw 310 will remain stably at the current screw depth. At the same time, the continuous preload of the elastic element 320 ensures that the interface module 200 is always firmly pressed against the end of the screw 310, thereby eliminating potential gaps and wobbling. In this way, the interface module 200 is stably locked in the new adjusted position.

[0038] In another embodiment, the adjustment assembly includes a screw and a mating nut. The screw, for example, a long rod with precision external threads, is mounted within the interface frame 100. Its two ends are rotatably connected to the interface frame 100 via structures such as bearings or bushings. This means that the screw itself can rotate freely about its axis, but its axial position relative to the interface frame 100 is fixed. The axis of the screw is typically parallel to the first direction in which the interface module 200 needs to move. The nut is fitted onto the screw, its internal threads engaging with the external threads of the screw to form a standard threaded connection. Unlike a regular nut, this nut is fixedly connected to the interface module 200 (e.g., embedded in the housing of the interface module 200 or connected to it via a bracket or welding), but it cannot rotate with the screw. When the position of the interface module 200 needs to be adjusted, the user rotates the screw in some way (e.g., by providing a knob or cross-shaped notch at one end). Since the nut is fixed to the interface module 200 and cannot rotate, when the screw rotates, according to the motion conversion principle of the threaded pair, the nut will translate along the axis of the screw (i.e., the first direction). Because the interface module 200 and the nut are fixed together, the translation of the nut will directly drive the interface module 200 to slide synchronously within the interface frame 100 along the first direction. The rotation direction of the screw determines the movement direction of the interface module 200, and the rotation angle of the screw corresponds to the movement distance of the interface module 200. Once the interface module 200 is adjusted to the desired precise position, the user can stop rotating the screw. Because the threaded pair usually has high friction and self-locking characteristics, the relative position of the screw and nut will remain unchanged when there is no external force driving the rotation. Therefore, the interface module 200 is stably fixed in the adjusted new position, resisting vibration and external forces, and will not experience accidental displacement.

[0039] Secondly, embodiments of this application provide an electronic device.

[0040] The electronic device of the embodiment includes a housing, a circuit board disposed within the housing, and an interface fine-tuning device according to any embodiment of the first aspect. The interface frame 100 is fixedly connected to the main circuit board, and the conductive track is electrically connected to the main circuit board. Because the electronic device of the embodiment is equipped with the interface fine-tuning device according to any embodiment of the first aspect, the position of the connector relative to the housing can be adjusted, so that the connector is better aligned with the opening in the housing.

[0041] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
