Description

Technical Field

[0001] This utility model relates to the field of wireless network card technology, specifically a non-detachable wireless network card USB interface structure. Background Technology

[0002] With the rapid development of wireless communication technology, wireless network cards (NICs), as an important component for various electronic devices to access networks, are widely used in laptops, desktops, smart terminals, and other devices. Among them, the USB interface, due to its strong versatility and convenient plug-and-play features, has become one of the mainstream methods for connecting wireless NICs to host devices. However, in actual use, the traditional USB interface structure still has some significant defects, especially in terms of preventing disconnection and connection stability, which urgently need improvement.

[0003] Currently, common USB interfaces typically rely on the physical contact between metal contacts on the interface tongue and corresponding contacts inside the device's female port to achieve signal transmission, and are initially secured by a simple elastic latch structure on the interface shell. However, due to the small size and limited structural space of USB interfaces, their elastic latches are often designed with relatively simple elasticity and insufficient holding force. When the device is subjected to vibration, movement, or external pulling, the interface is prone to loosening or even detachment, leading to signal transmission interruption and affecting network connection stability and user experience. This problem is particularly prominent in vibrating environments such as mobile devices or industrial sites.

[0004] Furthermore, traditional USB interface shielding shells are mostly manufactured using integral stamping or welding processes. While these offer some protection against electromagnetic interference (EMI), their structural strength and stability in conjunction with the plastic mounting housing remain insufficient. Especially after repeated plugging and unplugging, the metal shielding shell is prone to deformation, causing the elastic latches to fail and further reducing connection reliability. On the other hand, existing USB interfaces typically require users to manually unplug them, which is inconvenient in confined spaces or where interfaces are densely packed, and can easily damage the interface or connected devices due to improper force. Utility Model Content

[0005] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a non-detachable USB interface structure for wireless network cards, which effectively solves the core pain point of easy detachment of the USB interface of wireless network cards, realizes convenient plug-and-play operation and excellent compatibility, and has high practical value and market prospects.

[0006] The technical solution adopted by this utility model to achieve the above objectives is: a wireless network card USB interface structure that prevents detachment, including a mounting shell, a shielding shell, and a tongue, wherein the shielding shell is integrated into the mounting shell in a semi-embedded form, and the tongue is integrated into the shielding shell.

[0007] It also includes an elastic pressure member, a transmission member, and an operation button. The elastic pressure member is disposed on both sides of the shielding shell and has an outward expansion tendency. The elastic pressure member has an action port arranged inside the shielding shell. The action port has an oblique action section A. The transmission member is slidably installed on the inner wall of the shielding shell and slides along the opening direction of the shielding shell. The transmission member has an action button arranged in the action port. The action button has an oblique action section B that fits against the oblique action section A. The operation button is assembled on the mounting shell and protrudes to the top of the mounting shell. The operation button is linked with the transmission member.

[0008] Based on the above technical solutions, in order to facilitate the nesting and plugging of this type of USB interface with the USB female port and to ensure that the transmission component can effectively act on the elastic pressure component, the following technical solution is provided.

[0009] The elastic pressure member includes a connecting section, a positioning section, and a mating section connected in sequence. The connecting section is connected to the shielding shell and extends obliquely outward to the outer side of the shielding shell. The mating section extends inward to the inner side of the shielding shell. The function port is provided on the mating section. The positioning section is configured as an arc-shaped structure.

[0010] Based on the above technical solutions, the following technical solutions are provided to ensure that the transmission component can slide stably in the shielded housing.

[0011] The inner side of the shielding shell is provided with a guide slot, and the sliding claw of the action key can be moved into the guide slot.

[0012] Based on the above technical solutions, in order to ensure that the lifting and lowering movement of the operation buttons can drive the transmission components to slide stably, the following technical solutions are provided.

[0013] Connecting plates are fixedly connected to both sides of the operation button. A pin is fixedly connected to the outer end of the connecting plate. The side wall of the shielding shell and the transmission component are respectively provided with longitudinal guide grooves and oblique guide grooves. The end of the pin is nested and inserted with the longitudinal guide grooves and oblique guide grooves.

[0014] Based on the above technical solutions, in order to ensure that the operation button can automatically reset when it is released from pressure, thereby driving the transmission component to retract automatically and causing the elastic pressure component to automatically expand outward under elastic force, the following technical solution is provided.

[0015] The bottom of the operation button is provided with an assembly groove, and a return spring is provided in the assembly groove. The two ends of the return spring are respectively in contact with the mounting shell and the operation button.

[0016] The beneficial effects of this utility model are:

[0017] 1. By directly cutting and bending the shielding shell to form an elastic clamping component, it expands outward in its natural state, generating strong and reliable positive pressure and friction with the inner wall of the USB female port, forming a firm snap-fit. This one-piece molded elastic clamping component structure is simple and effective, fundamentally solving the problem of interface loosening and detachment caused by vibration and pulling, and greatly improving the connection stability of the wireless network card in complex usage environments.

[0018] 2. The unlocking mechanism, consisting of an operation button, a transmission component, and an angled action section, allows for easy release of the jamming state by simply pressing the operation button. The interaction of angled action section B and angled action section A converts vertical pressure into horizontal movement that causes the elastic pressure element to contract inward. This design avoids the significant force and inconvenience required for manually plugging and unplugging traditional USB interfaces. Especially in space-constrained or densely packed interface situations, operation is easier and more precise, effectively reducing the risk of damage to interfaces and ports.

[0019] 3. The transmission component is specially designed as a thin sheet structure, which ensures that when the entire interface is inserted into the standard USB female port, the transmission component can be completely accommodated in the space reserved inside the interface, and will not interfere with the spatial movement of any components such as the tongue and contacts inside the USB female port, thus ensuring complete compatibility with the standard USB interface and smooth insertion and removal.

[0020] 4. By incorporating a reset spring, the operating button and transmission components automatically reset after release. Simultaneously, the elastic pressure component quickly returns to its initial expanded state, preparing for the next insertion, removal, and engagement. The entire mechanism operates smoothly and reliably, requiring no manual adjustment and providing an excellent user experience.

[0021] 5. A guide groove is provided on the inner side of the shielding shell so that the action key on the transmission component can slide stably along the predetermined trajectory, effectively preventing the transmission component from deviating or jamming during the movement, and ensuring the efficiency of force transmission and the smoothness and accuracy of the entire unlocking action.

[0022] 6. Key components such as elastic clamps and guide slots are made directly from the base material of the shielding shell by cutting and bending, which reduces the number of parts, simplifies the assembly process, improves production efficiency and structural integrity, and helps to reduce costs and ensure product quality consistency.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 A non-detachable wireless network card USB interface structure includes a mounting shell 1, a shielding shell 2, and a tongue 3. The shielding shell 2 is integrated into the mounting shell 1 in a semi-embedded form, and the tongue 3 is integrated into the shielding shell 2.

[0031] The mounting housing 1 is made of plastic to ensure that the USB interface, antenna, circuit board and related cables can be effectively assembled on it. The shielding housing 2 and the tongue 3 are the main components of the USB interface, so as to realize the nested plugging of the wireless network card with the USB interface of the relevant network device and realize data transmission.

[0032] The shielding shell 2 is made of nickel-plated copper or stainless steel, which wraps around the tongue 3 and enables nested insertion with the interface of the network device, and serves to shield electromagnetic interference. The tongue 3 is usually made of plastic and is used to fix and isolate the various metal contacts on it so that the metal contacts can be connected to the corresponding contacts of the network device interface.

[0033] It also includes an elastic pressure member 4, a transmission member 5, and an operation button 6. The elastic pressure member 4 is disposed on both sides of the shielding shell 2 and has an outward expansion tendency. The elastic pressure member 4 has an action port 41 arranged inside the shielding shell 2. An oblique action section A42 is provided in the action port 41. The transmission member 5 is slidably installed to the inner wall of the shielding shell 2 and slides along the opening direction of the shielding shell 2. An action key 51 is arranged in the action port 41 on the transmission member 5. An oblique action section B52 is provided on the action key 51 that is in contact with the oblique action section A42. The operation button 6 is assembled to the mounting shell 1 and protrudes to the top of the mounting shell 1. The operation button 6 is linked with the transmission member 5.

[0034] The elastic clamping member 4 is manufactured by directly cutting and bending the shielding shell. Because it protrudes to the outside of the shielding shell, it can nest and snap into the USB female port on the network device during insertion, so that the USB interface provided in this application can be stably snapped into the USB female port. Due to its manufacturing process, the elastic clamping member 4 has a certain degree of elasticity and can deform under the action of force. When it is necessary to remove the USB interface of the wireless network card, the part protruding from the outside of the shielding shell can be retracted inward and separated from the inner wall of the USB female port, thereby facilitating the removal of the USB interface.

[0035] The design of the operating port 41 ensures the normal operation of the operating key 51 within it. The transmission component 5 can be driven by the operation button 6 for coordinated operation. When the operation button 6 is pressed down, it drives the transmission component 5 to slide towards the opening side of the shielding shell 2. At this time, the inclined action segment B52 on the operating key 51 applies force to the inclined action segment A42, thereby causing the elastic pressure member 4 to retract inward, facilitating the unplugging of the USB interface. When the operation button 6 is deactivated, both the operation button 6 and the transmission component 5 are reversed and reset. At this time, the operating key 51 cancels its action on the inclined action segment A42 in the elastic pressure member 4, and the elastic pressure member 4 can reset again and extend outward from the shielding shell 2 to provide a positioning and anti-dislodgement function.

[0036] It should be emphasized that the thickness of the transmission component 5 should be set below 0.50mm. When the transmission component 5 is inserted into the USB female port along with the shielding shell 2, the thinner transmission component 5 can avoid spatial movement interference with the components in the USB female port.

[0037] To facilitate nested connection between this type of USB interface and the USB female port, and to ensure that the transmission component 5 can effectively act on the elastic pressure component 4, the following technical solution is provided.

[0038] The elastic pressure member 4 includes a connecting section 43, a positioning section 44, and a mating section 45 connected in sequence. The connecting section 43 is connected to the shielding shell 2 and extends outward at an angle to the outside of the shielding shell 2. The mating section 45 extends inward to the inside of the shielding shell 2. The function port 41 is provided on the mating section 45. The positioning section 44 is configured as an arc-shaped structure.

[0039] The root of the connecting segment 43 extends from the shielding shell 2, providing elasticity. At the same time, due to its inclined setting, when inserted into the USB female port, the female port's shell can cause the positioning segment 44 and the mating segment 45 to retract inward, facilitating the normal insertion of the USB interface.

[0040] The positioning segment 44 can fit tightly against the USB female port and provide positive pressure due to elasticity to increase the frictional force with the USB female port, further preventing the USB interface from falling off. The mating segment 45 extends into the inner side of the shielding shell 2, enabling the function port 41 and the oblique function segment A42 provided on it to effectively cooperate with the transmission component 5 and function key 51 provided on the inner side of the shielding shell 2.

[0041] To ensure that the transmission component 5 can slide stably within the shielding housing 2, the following technical solution is provided.

[0042] The inner side of the shielding shell 2 is provided with a guide slot 21, and the sliding claw of the function key 51 can be moved into the guide slot 21.

[0043] The guide slot 21 is also processed by cutting and bending on the substrate of the shielding shell 2, which can cover the action key 51 on the inside, thereby ensuring that the transmission component 5 with the action key 51 slides stably along the opening direction.

[0044] To ensure that the elastic clamping member 4 can effectively engage with the inner wall of the USB female port, two sets of elastic clamping members 4 are provided on both sides of the shielding shell 2. The elastic clamping members 4 on both sides are arranged symmetrically. Two sets of action keys 51 are provided on each of the transmission members 5 on the inner side of the shielding shell 2, which cooperate with the two sets of elastic clamping members 4 on the corresponding side.

[0045] To ensure that the lifting and lowering movement of the operation button 6 can drive the transmission component 5 to slide stably, the following technical solution is provided.

[0046] The two sides of the operation button 6 are fixedly connected to the connecting plate 61. The outer end of the connecting plate 61 is fixedly connected to the pin 62. The side wall of the shielding shell 2 and the transmission component 5 are respectively provided with longitudinal guide groove 22 and oblique guide groove 53. The end of the pin 62 is nested and inserted with the longitudinal guide groove 22 and oblique guide groove 53.

[0047] The connecting plate 61 is fixedly connected to the bottom sides of the operating button 6 by bolts 63. When the operating button 6 drives the connecting plate 61 and the pin 62 to move vertically downward, the pin 62 can slide stably in the longitudinal guide groove 22. At the same time, the pin 62 can cooperate with the inclined guide groove 53, thereby driving the transmission component 5 to slide stably.

[0048] The connecting plate 61 and the operation button 6 are designed separately to facilitate assembly and processing. The connecting plate 61 and the pin 62 are both hidden in the mounting housing 1 to ensure the stability of its operation.

[0049] To ensure the stability of the linkage combination, each set of connecting plates 61 is provided with two sets of pins 62 arranged side by side. Each side of the corresponding shielding shell 2 and the corresponding transmission component 5 are provided with longitudinal guide grooves 22 and oblique guide grooves 53 that respectively cooperate with the two sets of pins 62.

[0050] To ensure that the operation button 6 can automatically reset when it is released from pressure, thereby causing the transmission component 5 to retract automatically and the elastic pressure component 4 to expand outward automatically under elastic force, the following technical solution is provided.

[0051] The bottom of the operation button 6 is provided with an assembly groove 64, and a return spring 65 is provided in the assembly groove 64. The two ends of the return spring 65 are respectively in contact with the mounting housing 1 and the operation button 6.

[0052] The mounting groove 64 provides mounting space for the return spring 65, thus ensuring its stable installation in the narrow space inside the housing 1. The return spring 65 provides an upward force to the operation button 6. When the operation button 6 is released, it can automatically spring upward, thereby driving the transmission component 5 to reset synchronously. After the transmission component 5 and the operation button 51 on it release their effect on the elastic pressure component 4, the elastic pressure component 4 can automatically expand outward.

[0053] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0054] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
