Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a non-standard connector structure. Background Technology

[0002] The Type-C connector is a USB interface standard characterized by its small size, high pluggability, and unrestricted insertion / removal orientation. Type-C interfaces are widely used in various devices, including PCs, mobile phones, and tablets.

[0003] Existing Type-C connector designs use a 24-pin array, such as Figure 4 As shown, each row has 12 pins, supporting reversible insertion. However, to achieve reversible insertion, only 12 pins are active during use, meaning the 12 pins in the top and bottom rows are repeated, which cannot meet the needs of more than 12 pins. Devices with high requirements for data transmission, power supply, and multi-functional integration typically require more active pins, such as high-performance laptops, professional video editing equipment, and high-performance multi-interface docking stations. Directly increasing the number of pins would increase the connector's size. Therefore, a non-standard connector structure needs to be designed to solve this problem. Utility Model Content

[0004] The main purpose of this application is to propose a non-standard connector structure, which aims to solve the problem that existing Type-C connectors, with no change in size, only have 12 effective pins and cannot meet the needs of more than 12 effective pins.

[0005] To achieve the above objectives, the non-standard connector structure proposed in this application includes: a plug, a housing, and a tongue. The housing and the tongue are both mounted on the plug. The housing has an opening at one end away from the plug. The tongue is disposed inside the housing. A plurality of pins are arranged sequentially on the tongue. The number of pins is greater than 12 and less than or equal to 24. The cross-section of the housing is asymmetrical vertically and / or horizontally.

[0006] Optionally, the number of pins is 22, and the 22 pins are equidistantly distributed on the first and second surfaces opposite to the tongue.

[0007] Optionally, the cross-section of the outer shell is a rectangular structure with one corner chamfered.

[0008] Optionally, the edges of the outer casing are provided with rounded corners.

[0009] Optionally, the outer casing is a structure made of metallic material.

[0010] Optionally, the outer shell and the corresponding opening of the tongue are both chamfered.

[0011] Optionally, a sealing ring is fitted onto the plug near the housing.

[0012] Optionally, the plug has an annular limiting groove corresponding to the sealing ring, the width of the limiting groove being the same as the width of the sealing ring, and the sealing ring being located within the limiting groove.

[0013] Optionally, the sealing ring includes an annular body, and two annular protrusions are integrally formed on the outer side of the body, with an annular sealing groove formed between the two protrusions.

[0014] Optionally, a retaining block is provided on the plug between the sealing ring and the outer shell.

[0015] This application's technical solution comprises a plug, a housing, and a tongue. Both the housing and the tongue are mounted on the plug. The housing has an opening at the end furthest from the plug, and the tongue is located inside the housing. The tongue has a plurality of pins arranged sequentially, with the number of pins being greater than 12 and less than or equal to 24. The housing has an asymmetrical cross-section, either vertically or horizontally. In use, each pin is effectively utilized. The housing provides protection and fixation, while the pins on the tongue transmit signals or power. When inserted into a corresponding socket, the pins connect with the contact points inside the socket, establishing circuit continuity. The asymmetrical structure of the housing provides a foolproof design, preventing incorrect insertion and increasing the uniqueness of the structure, making it suitable for specific application scenarios. The number of pins (greater than 12 and less than or equal to 24) allows the connector to be used in applications requiring more than 12 pins without changing its size. The limitation on the number of pins and the asymmetrical design of the housing enable this non-standard connector structure to meet the specific requirements of certain devices for the number of connection points and foolproof design, improving the connector's relevance and applicability.

[0029] Existing Type-C connector designs use a 24-pin array, such as Figure 4 As shown, each row has 12 pins, supporting reversible insertion. However, to achieve reversible insertion, only 12 pins are active during use, meaning the 12 pins in the top and bottom rows are repeated, which cannot meet the needs of more than 12 pins. Devices with high requirements for data transmission, power supply, and multi-functional integration typically require more active pins, such as high-performance laptops, professional video editing equipment, and high-performance multi-interface docking stations. Directly increasing the number of pins would increase the connector's size. Therefore, a non-standard connector structure needs to be designed to solve this problem.

[0030] In view of this, this application proposes a non-standard connector structure.

[0031] In the embodiments of this application, reference is made to Figures 1 to 3The aforementioned non-standard connector structure includes: a plug 1, a housing 2, and a tongue 3. Both the housing 2 and the tongue 3 are mounted on the plug 1. The end of the housing 2 away from the plug 1 is open. The tongue 3 is located inside the housing 2. A plurality of pins 4 are arranged sequentially on the tongue 3. The number of pins 4 is greater than 12 and less than or equal to 24. The cross-section of the housing 2 is asymmetrical vertically and / or horizontally. Electrical signals or power are transmitted by contacting the pins 4 with the external circuit. The asymmetrical structure of the housing 2 can prevent incorrect insertion and also increases the uniqueness of the structure, making it suitable for specific application scenarios.

[0032] In this embodiment, there are 22 pins 4, which are equidistantly distributed on the first and second surfaces opposite to the tongue 3. During connection, the pins 4 on both sides are simultaneously connected to the corresponding socket contact points to realize the transmission of signals or power. The equidistant distribution of pins 4 is conducive to uniform transmission of signals or power, ensuring that the electrical performance of each pin 4 is consistent, reducing signal interference and transmission errors, further optimizing the electrical performance of the connector, and improving the stability and reliability of signal transmission.

[0033] In this embodiment, the cross-section of the outer shell 2 is a rectangular structure with one corner chamfered; specifically, the cross-section of the outer shell 2 can also be a right trapezoidal structure; making the cross-section of the outer shell 2 asymmetrical both vertically and horizontally serves as a foolproof method to prevent incorrect insertion, while also increasing the uniqueness of the structure and making it suitable for specific application scenarios.

[0034] In this embodiment, the corners of the outer shell 2 are all provided with a rounded transition structure; the rounded transition eliminates the stress concentration points at the corners, so that the outer shell 2 can bear the force more evenly when subjected to external force, thereby improving the impact resistance and wear resistance of the outer shell 2; further enhancing the mechanical properties of the outer shell 2, extending the service life of the connector, and also making the appearance of the connector smoother and more beautiful.

[0035] In this embodiment, the outer shell 2 is made of metal; the metal outer shell 2 has good conductivity and heat dissipation. When the connector is working, it can quickly dissipate the heat generated during the transmission of pins 4, and also play a role in electromagnetic shielding. Specifically, the outer shell 2 can be made of metal materials such as stainless steel, copper alloy, and aluminum alloy. To improve corrosion resistance, conductivity, and weldability, the outer shell 2 can also be electroplated. This improves the heat dissipation performance and electromagnetic compatibility of the connector, ensures the stability and reliability of the connector under high-frequency, high-power transmission conditions, and reduces the impact of electromagnetic interference on peripheral equipment.

[0036] In this embodiment, the opening ends of both the housing 2 and the tongue 3 are chamfered, forming a tapered guide surface at the insertion end of the connector. This facilitates alignment with the socket and prevents the opening ends of the tongue 3 and housing 2 from scratching the socket or other components during insertion. The chamfer guides the connector to insert smoothly and reduces resistance during insertion, improving the ease of connector insertion and removal, reducing the risk of damage to the connector and socket, and increasing the success rate and reliability of the connection.

[0037] In this embodiment, a sealing ring 5 is fitted on the plug 1 near the outer shell 2. When the connector is inserted into the socket or connected to other components, the sealing ring 5 is compressed, filling the gap between the connector and the external components. The elastic deformation of the sealing ring 5 forms a sealing barrier between the connector and the external components, preventing dust, moisture and other impurities from entering the connector. At the same time, it can also prevent the internal electrical components from being affected by the external environment. This improves the protective performance of the connector, prevents dust, moisture and other substances from causing corrosion or short circuits inside the connector, extends the service life of the connector, and ensures its normal operation under harsh environmental conditions and other special circumstances.

[0038] In this embodiment, an annular limiting groove is provided on the plug 1 corresponding to the sealing ring 5. The width of the limiting groove is the same as the width of the sealing ring 5, and the sealing ring 5 is located in the limiting groove. The limiting groove restricts the position of the sealing ring 5, so that it will not move axially or radially when squeezed. This ensures the stability of the sealing ring 5 during installation and use, so that it can always maintain a good sealing effect. In addition, it improves the installation accuracy and stability of the sealing ring 5, ensures the reliability of the sealing performance, and avoids the sealing failure problem caused by the displacement of the sealing ring 5.

[0039] In this embodiment, the sealing ring 5 includes an annular body 501. Two annular protrusions 502 are integrally formed on the outer side of the body 501, and an annular sealing groove 503 is formed between the two protrusions 502. The protrusions 502 can generate greater elastic deformation when compressed, and fit tightly with the external parts. The sealing groove 503 can accommodate some impurities or deformation, making the seal more reliable. This optimizes the structure of the sealing ring 5, improves the sealing performance, and can better adapt to different connection surfaces and working environments, thereby enhancing the protection capability of the connector.

[0040] In this embodiment, a locking block 6 is provided on the plug 1 between the sealing ring 5 and the outer shell 2; when connected to the socket, the locking block 6 can restrict the axial movement of the outer shell 2, prevent the outer shell 2 from loosening or shifting during use, thereby ensuring the stability of the overall structure of the connector, improving the structural stability of the connector, preventing the outer shell 2 from loosening and damaging the sealing ring 5, thus ensuring the sealing performance and normal operation of the connector, and also enhancing the overall reliability of the connector.

[0041] In this embodiment, a limiting step 7 is also provided on the plug 1 to limit the length of the plug 1 inserted into the socket, and also to allow the user to intuitively feel whether the plug 1 is inserted in place, making it convenient for people to use.

[0042] This application's technical solution comprises a plug, a housing, and a tongue. Both the housing and the tongue are mounted on the plug. The housing has an opening at the end furthest from the plug, and the tongue is located inside the housing. The tongue has a plurality of pins arranged sequentially, with the number of pins being greater than 12 and less than or equal to 24. The housing has an asymmetrical cross-section, either vertically or horizontally. In use, each pin is effectively used. The housing provides protection and fixation, while the pins on the tongue transmit signals or power. When inserted into a corresponding socket, the pins connect with the contact points inside the socket, establishing circuit continuity. The asymmetrical structure of the housing provides a foolproof design, preventing incorrect insertion and increasing the uniqueness of the structure, making it suitable for specific application scenarios. The number of pins (greater than 12 and less than or equal to 24) allows the connector to be used in applications requiring more than 12 pins. The limitation on the number of pins and the asymmetrical design of the housing enable this non-standard connector structure to meet the specific requirements of certain devices regarding the number of connection points and foolproof design, improving the connector's relevance and applicability.

[0043] The above description is merely an optional embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
