Description

Technical Field

[0001] This utility model relates to the field of adapter technology, and in particular discloses a straight-through female to female adapter. Background Technology

[0002] In the field of electronic device connectivity, through-female to female adapters are used to achieve electrical connections between devices with similar female interfaces. Their conventional structure includes a housing and internal adapter elements, with circuit connection achieved through a circuit connection unit, a first connector, and a second connector. However, existing adapters suffer from several technical bottlenecks: firstly, the connection points between the terminals and connecting pieces are prone to loosening and breakage due to frequent insertion and removal, affecting the stability of the electrical connection; secondly, the robustness of the assembly structure between the housings is insufficient, making them prone to separation under vibration or external force, thus limiting product lifespan and failing to meet the stringent requirements of high-performance electronic devices for connection stability and reliability. Utility Model Content

[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a straight-through female to female adapter.

[0004] To achieve the above objectives, this utility model provides a through-female to through-female adapter, comprising a first housing, a second housing mounted on the first housing, and an adapter element; the first housing and the second housing together form an accommodating chamber, and the adapter element is installed in the accommodating chamber. The adapter element includes a circuit connection unit, a first connector, and a second connector, with the first connector and the second connector respectively disposed at both ends of the circuit connection unit, and the first connector and the second connector respectively protruding from both ends of the accommodating chamber; the connection points between the first connector and the second connector and the circuit connection unit are each provided with a reinforcing structure, the reinforcing structure including a protective shell and a U-shaped metal reinforcement provided on the protective shell, the connector being installed inside the protective shell, the U-shaped metal reinforcement respectively accommodating and clamping the circuit connection unit, and the U-shaped metal reinforcement of the protective shell of the two connectors respectively clamping both ends of the circuit connection unit.

[0005] The first and second housings are joined to form a accommodating chamber, which houses the adapter element consisting of a circuit connection unit and a second connector. The connection between the terminals and the connecting piece utilizes a composite structure of a protective shell and a U-shaped metal reinforcement. The reinforcement is fixed to both sides of the circuit connection unit via welding, while simultaneously encasing the terminals within the protective shell. This design offers significant advantages: In terms of mechanical reinforcement, the U-shaped metal reinforcement enhances the welding strength between the terminals and the connecting piece, preventing loosening or breakage due to frequent insertion and removal; in terms of electrical protection, the protective shell isolates external interference, ensuring stable electrical connections; and in terms of ease of assembly, the split-shell structure facilitates the installation and maintenance of internal components, improving production efficiency and effectively solving the problems of poor connection reliability and difficult assembly and maintenance associated with traditional adapters.

[0006] The first housing is provided with an inverted mounting block, and the second housing is provided with a mounting groove. The free end of the inverted mounting block is provided with an outwardly protruding engaging part. The upper surface of the engaging part is a sloping structure, and the lower surface is a vertical stop surface. The first housing is installed into the mounting groove of the second housing via the engaging part, and the inner groove sidewall of the mounting groove abuts against the vertical stop surface.

[0007] Align the inverted mounting block of the first housing with the mounting groove of the second housing. Utilizing the beveled structure on the upper surface of the engaging part, pressing the first housing guides the inverted mounting block smoothly into the mounting groove. Once the engaging part is fully inside the mounting groove, its vertical stop surface fits tightly against the inner wall of the mounting groove, forming a robust locking structure that restricts the relative separation of the first and second housings. This design offers significant advantages: firstly, the cooperation between the beveled surface and the vertical stop surface enables quick and precise assembly, simplifying the assembly process and improving production efficiency; secondly, the vertical stop surface provides strong limiting resistance, effectively preventing the two housings from loosening due to external pulling or vibration during use, enhancing the overall stability and reliability of the adapter structure. Furthermore, disassembly only requires moderate force to overcome the locking resistance, combining the dual advantages of convenient installation and a secure connection.

[0008] Both the first and second housings have reinforcing ribs protruding from their inner sides and located within the accommodating cavity. The inner reinforcing ribs are used to abut against and hold the adapter element.

[0009] When assembling the adapter, the adapter element is placed into the receiving cavity, and the reinforcing ribs on both sides precisely abut and clamp the adapter element. This design has multiple beneficial effects: From a structural strength perspective, the presence of the reinforcing ribs significantly improves the rigidity and deformation resistance of the housing, reducing the risk of housing damage due to external pressure; in terms of component fixation, the reinforcing ribs provide a stable clamping effect on the adapter element, preventing it from shaking or shifting within the receiving cavity, ensuring the relative positional stability of components such as the circuit connection unit, the first connector, and the second connector, and avoiding electrical connection failures caused by component displacement; at the same time, the clamping effect of the reinforcing ribs also helps to distribute the stress on the adapter element during insertion and removal, extending the overall service life of the adapter and ensuring the reliability of the product in complex operating environments.

[0010] The second housing has a limiting protrusion on its side, and the first housing has an elastic arm on its side. The limiting protrusion and the elastic arm are parallel to each other, and the adapter is snapped onto the external socket via the limiting protrusion and the elastic arm.

[0011] During manufacturing, limiting protrusions are machined on the side of the second housing, and an elastic arm structure is formed on the side of the first housing, ensuring that the two are parallel. When connecting the adapter to an external socket, first align the limiting protrusion with the limiting groove on one side of the socket, and simultaneously press the elastic arm to induce elastic deformation. Push the adapter into the socket, and as the elastic arm recovers its deformation, it snaps into the slot on the other side of the socket, working in conjunction with the limiting protrusion to achieve a secure connection with the external socket. This design offers significant advantages: firstly, the parallel limiting protrusions and elastic arm form a dual positioning structure, significantly improving the accuracy and stability of the connection between the adapter and the external socket, avoiding poor contact due to misalignment; secondly, the elastic snap-fit ​​design of the elastic arm allows the adapter to be easily inserted into the external socket while remaining securely fixed during use, preventing accidental detachment; furthermore, this structure effectively disperses the force during insertion and removal, reducing impact on the internal components of the adapter and improving the product's durability and reliability.

[0012] The end of the elastic arm is provided with a plug-in part, and the plug-in part is provided with an inclined guide surface. The elastic arm is plugged into the external socket through the inclined guide surface, and the adapter is pulled out of the external socket by pressing the elastic arm inward.

[0013] The insertion part and inclined guide surface at the end of the flexible arm are integrally formed by injection molding or metal stamping. When the adapter is plugged into an external socket, the inclined guide surface and the opening of the socket cooperate to guide the insertion part to slide smoothly into the socket slot, reducing insertion resistance and avoiding structural damage caused by brute force. When the adapter needs to be disassembled, the flexible arm is pressed inward, causing the inclined guide surface of the insertion part to slide relative to the inner wall of the socket slot. Utilizing the mechanical properties of the inclined structure, the external force required for removal is reduced, achieving easy disassembly. The beneficial effects of this design are significant: First, the guiding function of the inclined guide surface optimizes the smoothness of the insertion and removal operation, improving the user experience; second, by reducing the insertion and removal force, it effectively reduces wear on the flexible arm, socket slot, and other structures, extending the service life of the adapter and socket; third, the inclined guide surface, combined with the elastic return characteristics of the flexible arm, can form a tighter locking effect when inserted, enhancing the stability of the adapter connection and preventing it from falling off due to vibration or external pulling during use.

[0014] The free end of the connector is rounded.

[0015] When the adapter is inserted into an external socket, the rounded corner design effectively reduces friction and collision between the plug and the socket wall, avoiding surface wear and scratches caused by sharp corners, while reducing insertion resistance and making the insertion and removal process smoother. During disassembly, the rounded corner structure can also prevent stress concentration and avoid cracking or deformation of the plug during the stress process.

[0016] Both the first and second housings are provided with heat dissipation holes, and dustproof screens are also provided on the heat dissipation holes to prevent dust from entering the accommodating chamber.

[0017] Heat dissipation holes are provided on the first and second housings, and dustproof mesh is fixed to the heat dissipation holes using processes such as hot melting, ultrasonic welding, or adhesive bonding. During use, the heat generated by the adapter components can exchange heat with the outside air through the heat dissipation holes, achieving rapid heat dissipation. The dustproof mesh effectively prevents dust, debris, and other impurities from entering the housing chamber, avoiding their adhesion to the surfaces of components such as the circuit connection unit, the first connector, and the second connector, which could affect electrical performance. This design offers significant advantages: First, the heat dissipation holes accelerate heat dissipation, preventing performance degradation or shortened lifespan of the adapter components due to overheating, ensuring the stability of the adapter under long-term operation. Second, the combination of the dustproof mesh and heat dissipation holes balances heat dissipation requirements with dust prevention, preventing short circuits, poor contact, and other malfunctions caused by dust accumulation, thus improving product reliability and durability. Third, by optimizing heat dissipation and dust prevention performance, the frequency of product maintenance is reduced, operating costs are lowered, and the product's competitiveness in the market is enhanced.

[0018] The protective shell is provided with elastic pieces opposite to the first connector and the second connector, and the elastic pieces and terminals together abut against the external connector.

[0019] The elastic tabs on the protective shell can be integrally molded (using elastic plastic material) or separately stamped and then embedded (using metal elastic material) to ensure precise alignment with the first and second connectors. When the external connector is inserted, the elastic tab first undergoes elastic deformation, and then, together with the terminal, tightly abuts against the two sides of the connector. This design brings several beneficial effects: First, the elastic tab can adaptively adjust the contact pressure with the external connector, ensuring reliable electrical connection even with minor tolerances in the connector dimensions, thus improving product compatibility; second, the elastic tab shares the insertion and extraction force borne by the terminal, reducing wear and deformation caused by frequent insertion and extraction, and extending service life; third, the double contact structure formed by the elastic tab and the terminal increases the contact area, reduces contact resistance, improves current transmission stability, effectively avoids problems such as overheating and signal attenuation caused by poor contact, and significantly enhances the electrical performance and reliability of the adapter.

[0020] The insertion ends of the first connector and the second connector are provided with an anti-oxidation plating layer, which consists of a nickel base layer, a palladium intermediate layer and a gold surface layer from the inside out.

[0021] First, a nickel underlayer is plated onto the insertion ends of the first and second connectors. Nickel's excellent corrosion resistance and strong adhesion to the substrate provide basic protection for the terminals. Next, a palladium intermediate layer is plated, which possesses stable chemical properties and good hardness, further enhancing the protective performance. Finally, a gold surface layer is plated, as gold has excellent chemical stability and conductivity. When the adapter is in use, the anti-oxidation plating effectively isolates the terminals from air and moisture, preventing oxidation and rust on the terminal surface. This design offers significant advantages: firstly, it extends the service life of the first and second connectors, reducing problems such as poor contact and increased resistance caused by oxidation; secondly, the excellent conductivity of the gold surface layer ensures the stability of the electrical connection, reduces signal transmission loss, and improves the electrical performance of the adapter; thirdly, the multi-layer plating structure improves the wear resistance of the terminal surface, maintaining good contact performance even during frequent insertion and removal, ensuring long-term stable operation of the adapter.

[0022] The housing has a stop panel that blocks the opening of the receiving chamber. The stop panel has an interface that communicates with the receiving chamber to facilitate the insertion of external plugs and connectors. The stop panel is used to prevent collisions with the protective housing.

[0023] The first and second connectors can be Type-C, HDMI, or USB interfaces. In practical applications, the first and second connectors can be flexibly configured as Type-C, HDMI, or USB interfaces according to different usage scenarios and device requirements. When configured as a Type-C interface, it can be adapted to smartphones, laptops, and other devices that support this interface, enabling high-speed data transmission and fast charging. If an HDMI interface is used, it can be used for signal transmission between high-definition audio-visual devices, meeting the connection needs of home theaters, projectors, and other devices. The USB interface, with its wide compatibility, is suitable for connecting various data storage devices and peripheral accessories. The beneficial effects of this design are extremely prominent: First, it greatly expands the applicability of the adapter, achieving "one device, multiple uses," and improving the product's versatility and practicality. Second, it meets the diverse needs of different user groups in data transmission, audio-visual entertainment, and device connection, enhancing the product's market competitiveness. Third, the choice of multiple interface types allows the adapter to keep up with the development trend of electronic device interface technology, extending the product's market life cycle and providing users with longer-lasting value.

[0024] The beneficial effects of this utility model are as follows: It adopts a split double-shell structure, with a snap-fit ​​design between the inverted mounting block and the mounting groove, along with reinforcing ribs, heat dissipation holes, and a dustproof mesh. This ensures both a stable shell connection and heat dissipation protection for internal components, while also facilitating assembly and maintenance. The adapter element uses a "protective shell + U-shaped metal reinforcement" to enhance the welding strength of the terminals and connecting pieces, and is combined with an elastic sheet and anti-oxidation plating to improve electrical connection stability. Simultaneously, the dual positioning structure of the limiting protrusion and elastic arm, combined with the inclined guide surface and rounded corner design, optimizes the insertion and removal experience. Mechanically, it strengthens the structure's resistance to external forces and wear, extending its service life. Electrically, it ensures stable signal transmission and reduces contact resistance. In terms of application, multi-interface adaptation enables "one device for multiple uses," improving versatility and market competitiveness, effectively solving the problems of poor connection reliability and limited functionality in traditional adapters.

[0034] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0035] Please see Figures 1 to 7 As shown, this utility model discloses a through-female to through-female adapter, comprising a first housing 1, a second housing 2 mounted on the first housing 1, and an adapter element 3; the first housing 1 and the second housing 2 together form an accommodating chamber 4, and the adapter element 3 is installed in the accommodating chamber 4. The adapter element 3 includes a circuit connection unit 5, a first connector 6, and a second connector 7. The first connector 6 and the second connector 7 are respectively disposed at both ends of the circuit connection unit 5, and the first connector 6 and the second connector 7 respectively protrude from both ends of the accommodating chamber 4; the connection points of the first connector 6 and the second connector 7 with the circuit connection unit 5 are provided with a reinforcing structure, the reinforcing structure including a protective shell 8 and a U-shaped metal reinforcement 9 disposed on the protective shell 8, the connectors being installed inside the protective shell 8, and the U-shaped metal reinforcement 9 respectively accommodating and clamping the circuit connection unit 5, with the U-shaped metal reinforcement 9 of the protective shell 8 of the two connectors respectively clamping both ends of the circuit connection unit 5.

[0036] The first and second housings are joined to form a receiving chamber 4, which houses an adapter element 3 consisting of a circuit connection unit 5 and a second connector 7. The connection between the terminals and the connecting piece utilizes a composite structure of a protective shell 8 and a U-shaped metal reinforcement 9. The reinforcement is fixed to both sides of the circuit connection unit 5 via welding, while simultaneously enclosing the terminals within the protective shell 8. This design offers significant advantages: in terms of mechanical reinforcement, the U-shaped metal reinforcement enhances the welding strength between the terminals and the connecting piece, preventing loosening or breakage due to frequent insertion and removal; in terms of electrical protection, the protective shell 8 isolates external interference, ensuring stable electrical connections; and in terms of ease of assembly, the split-type housing structure facilitates the installation and maintenance of internal components, improving production efficiency and effectively solving the problems of poor connection reliability and difficult assembly and maintenance associated with traditional adapters.

[0037] The first housing 1 is provided with an inverted mounting block 11, and the second housing 2 is provided with a mounting groove 12. The free end of the inverted mounting block 11 is provided with an outwardly protruding engaging part. The upper surface of the engaging part is a sloping structure 14, and the lower surface is a vertical stop surface 15. The first housing 1 is installed into the mounting groove 12 of the second housing 2 via the engaging part. The inner groove sidewall of the mounting groove 12 stops and abuts against the vertical stop surface 15.

[0038] Align the inverted mounting block 11 of the first housing 1 with the mounting groove 12 of the second housing 2. Utilizing the inclined structure 14 on the upper surface of the engaging part, the inverted mounting block 11 can be guided smoothly into the mounting groove 12 when the first housing 1 is pressed. After the engaging part is fully inserted into the mounting groove 12, its vertical stop surface 15 fits tightly against the inner wall of the mounting groove 12, forming a robust locking structure that restricts the relative separation of the first housing 1 and the second housing 2. This design offers significant advantages: firstly, the cooperation between the inclined surface and the vertical stop surface 15 enables quick and precise assembly, simplifying the assembly process and improving production efficiency; secondly, the vertical stop surface 15 provides strong limiting resistance, effectively preventing the two housings from loosening due to external pulling or vibration during use, enhancing the stability and reliability of the overall adapter structure. Furthermore, disassembly only requires moderate force to overcome the locking resistance, combining the dual advantages of convenient installation and stable connection.

[0039] The first housing 1 and the second housing 2 both have reinforcing ribs 16 protruding from their inner sides and located in the accommodating chamber 4. The inner reinforcing ribs 16 are used to abut against and hold the adapter element 3.

[0040] When assembling the adapter, the adapter element 3 is placed into the receiving chamber 4, and the reinforcing ribs 16 on both sides precisely abut and clamp the adapter element 3. This design has multiple beneficial effects: from the perspective of structural strength, the presence of the reinforcing ribs 16 significantly improves the rigidity and deformation resistance of the housing, reducing the risk of housing damage caused by external pressure; in terms of component fixation, the reinforcing ribs 16 form a stable clamp for the adapter element 3, preventing it from shaking or shifting within the receiving chamber 4, ensuring the relative position stability of components such as the circuit connection unit 5, the first connector 6, and the second connector 7, and avoiding electrical connection failure caused by component displacement; at the same time, the clamping effect of the reinforcing ribs 16 can also help to disperse the stress on the adapter element 3 during insertion and removal, extending the overall service life of the adapter and ensuring the reliability of the product in complex operating environments.

[0041] The second housing 2 has a limiting protrusion 17 on its side, and the first housing 1 has an elastic arm 18 on its side. The limiting protrusion 17 and the elastic arm 18 are parallel to each other. The adapter is snapped onto the external socket via the limiting protrusion 17 and the elastic arm 18.

[0042] During manufacturing, limiting protrusions 17 are machined on the side of the second housing 2, and an elastic arm 18 is formed on the side of the first housing 1, ensuring that the two are arranged parallel to each other. When connecting the adapter to an external socket, first align the limiting protrusions 17 with the limiting groove on one side of the socket, and simultaneously press the elastic arm 18 to cause it to elastically deform. Then, push the adapter into the socket. As the elastic arm 18 recovers its deformation, it snaps into the slot on the other side of the socket, thus achieving a secure connection with the external socket in conjunction with the limiting protrusions 17. This design has significant advantages: firstly, the parallel limiting protrusions 17 and the elastic arm 18 form a dual positioning structure, significantly improving the accuracy and stability of the connection between the adapter and the external socket, avoiding poor contact due to misalignment; secondly, the elastic snap-fit ​​design of the elastic arm 18 allows the adapter to be easily inserted into the external socket while remaining securely fixed during use, preventing accidental detachment; furthermore, this structure effectively disperses the force during insertion and removal, reducing impact on the internal components of the adapter and improving the product's durability and reliability.

[0043] The end of the elastic arm 18 is provided with a plug-in portion 19, and the plug-in portion 19 is provided with an inclined guide surface 21. The elastic arm 18 is plugged into the external socket via the inclined guide surface 21, and the adapter is pulled out of the external socket by pressing the elastic arm 18 inward.

[0044] The insertion portion 19 at the end of the elastic arm 18 and the inclined guide surface 21 are integrally formed by injection molding or metal stamping. When the adapter is connected to an external socket, the inclined guide surface 21 cooperates with the opening of the socket to guide the insertion portion 19 to slide smoothly into the socket slot, reducing insertion resistance and avoiding structural damage caused by brute force insertion and removal. When it is necessary to disassemble the adapter, press the elastic arm 18 inward to make the inclined guide surface 21 of the insertion portion 19 slide relative to the inner wall of the socket slot. Utilizing the mechanical properties of the inclined structure 14, the external force required for removal is reduced, and easy disassembly is achieved. The design offers several significant advantages: First, the guiding function of the inclined guide surface 21 optimizes the smoothness of the insertion and removal operation, enhancing the user experience. Second, by reducing the insertion and removal force, it effectively reduces wear on structures such as the elastic arm 18 and the socket slot, extending the service life of the adapter and socket. Third, the inclined guide surface 21, combined with the elastic reset characteristic of the elastic arm 18, creates a tighter locking effect when inserted, enhancing the stability of the adapter connection and preventing it from falling off due to vibration or external pulling during use.

[0045] The free end of the plug-in portion 19 is provided with a rounded corner 22.

[0046] When the adapter is inserted into an external socket, the rounded corner 22 design can effectively reduce the friction and collision between the plug part 19 and the socket hole wall, avoid surface wear and scratches caused by sharp corners, and reduce insertion resistance, making the insertion and removal process smoother. During disassembly, the rounded corner 22 structure can also prevent stress concentration and prevent the plug part 19 from cracking or deforming during the stress process.

[0047] Both the first housing 1 and the second housing 2 are provided with heat dissipation holes 23, and the heat dissipation holes 23 are also provided with dustproof nets 24 to prevent dust from entering the accommodating chamber 4.

[0048] Heat dissipation holes 23 are provided on the first housing 1 and the second housing 2, and a dustproof mesh 24 is fixed to the heat dissipation holes 23 using processes such as hot melting, ultrasonic welding, or adhesive bonding. During use, the heat generated by the adapter element 3 can exchange heat with the outside air through the heat dissipation holes 23, achieving rapid heat dissipation. The dustproof mesh 24 effectively prevents dust, debris, and other impurities from entering the housing chamber 4, avoiding their adhesion to the surfaces of components such as the circuit connection unit 5, the first connector 6, and the second connector 7, which could affect electrical performance. This design offers significant advantages: First, the heat dissipation holes 23 accelerate heat dissipation, preventing the adapter element 3 from overheating and causing performance degradation or shortened lifespan, ensuring the stability of the adapter during long-term operation. Second, the combination of the dustproof mesh 24 and the heat dissipation holes 23 balances heat dissipation requirements with dust prevention, preventing short circuits, poor contact, and other malfunctions caused by dust accumulation, thus improving product reliability and durability. Third, by optimizing heat dissipation and dust prevention performance, the frequency of product maintenance is reduced, lowering operating costs and enhancing the product's competitiveness in the market.

[0049] The protective shell 8 is provided with an elastic piece 25 opposite to the first connector 6 and the second connector 7. The elastic piece 25 and the terminal together abut against the external connector.

[0050] The elastic tab 25 on the protective shell 8 can be integrally molded (using elastic plastic material) or separately stamped and then embedded (using metal elastic material) to ensure precise alignment with the first connector 6 and the second connector 7. When the external connector is inserted, the elastic tab 25 first undergoes elastic deformation, and then, together with the terminal, tightly abuts against the two sides of the connector.

[0051] The insertion ends of the first connector 6 and the second connector 7 are provided with an anti-oxidation plating layer 26, which consists of a nickel underlayer 27, a palladium intermediate layer 28 and a gold surface layer 29 from the inside to the outside.

[0052] First, a nickel underlayer 27 is plated onto the insertion ends of the first connector 6 and the second connector 7. Utilizing nickel's excellent corrosion resistance and strong adhesion to the substrate, it provides basic protection for the terminals. Next, a palladium intermediate layer 28 is plated on, possessing stable chemical properties and good hardness, further enhancing the protective performance. Finally, a gold surface layer 29 is plated on, as gold has excellent chemical stability and conductivity. When the adapter is in use, the anti-oxidation plating layer 26 effectively isolates the terminals from air and moisture corrosion, preventing oxidation and rust on the terminal surface. This design offers significant advantages: firstly, it extends the service life of the first connector 6 and the second connector 7, reducing problems such as poor contact and increased resistance caused by oxidation; secondly, the excellent conductivity of the gold surface layer 29 ensures the stability of the electrical connection, reduces signal transmission loss, and improves the electrical performance of the adapter; thirdly, the multi-layer plating structure improves the wear resistance of the terminal surface, maintaining good contact performance even during frequent insertion and removal, ensuring long-term stable operation of the adapter.

[0053] The housing has a stop panel 100 that stops the opening of the receiving chamber 4. The stop panel 100 has an interface that communicates with the receiving chamber 4 to facilitate the insertion of external plugs and connectors. The stop panel 100 is used to stop the impact on the protective housing 8.

[0054] The first connector 6 and the second connector 7 can be Type-C, HDMI, or USB interfaces. In practical applications, the first connector 6 and the second connector 7 can be flexibly configured as Type-C, HDMI, or USB interfaces according to different usage scenarios and device requirements.
