Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a USB 3.1 high-definition transmission connector. Background Technology

[0002] The USB 3.1 high-definition transmission connector, as a core component for high-definition data and audio / video transmission, achieves efficient synchronous transmission of high-definition data and audio / video with an ultra-high speed of 10Gbps. It can smoothly support 4K and even 8K high-definition image output and can connect to monitors, TVs, and other audio-visual devices without the need for additional adapters. It also features enhanced power supply capabilities, meeting the fast charging and data transmission needs of external storage devices, high-definition playback devices, and other scenarios, making it a core component for high-definition connectivity in audio-visual entertainment, office collaboration, and other scenarios.

[0003] Most connectors on the market currently use a pin-type assembly structure for the terminals and the core body. However, this pin-type structure has significant drawbacks in actual production, assembly, and use: the assembly of the terminals and the core body relies solely on the insertion and locking mechanism for fixation, lacking effective limiting and locking structures. This causes the terminals to easily tilt upwards during insertion and removal forces or long-term use. Furthermore, the lack of a precise positioning and guiding mechanism during pin assembly easily leads to misaligned pins and other assembly defects. These defects directly affect the contact stability of the connector, causing problems such as interruption of high-definition data and audio / video transmission, and signal attenuation.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a USB 3.1 high-definition transmission connector, comprising a metal shell, wherein a core body is installed inside the metal shell, and the core body includes a fixing part that snaps into the metal shell and a tongue plate for mating with a male connector. The core body is provided with a front terminal group and a rear terminal group. The front terminal group and the rear terminal group are respectively provided with a first welding end and a second welding end protruding from the rear end of the fixing part. The front terminal group and the rear terminal group are fixedly connected to the core body by a pre-embedded integrated injection molding method. The front terminal group includes side terminals on both sides and a middle terminal between the side terminals. Each of the side terminals and the middle terminal is provided with a bonding piece at one end. The bonding piece is used to bond with the internal electrical connection of the male connector when the male connector is plugged in to achieve a telecommunication connection. The end of the bonding piece is provided with a bent end that is embedded inside the tongue plate.

[0007] As a further embodiment of this utility model: a groove corresponding to the bonding piece is formed on the bottom surface of the tongue plate near the front end, and a first slot communicating with the groove is formed on the top surface of the tongue plate near the front end, and the bent end is fitted into the first slot.

[0008] As a further embodiment of the present invention: the side terminal has a connecting section that is connected to the first welding end, and the connecting section is connected to the corresponding bonding piece after being bent laterally; The intermediate terminal has a first limiting spring that connects to the corresponding bonding piece.

[0009] As a further embodiment of this utility model: the rear terminal group is also provided with a limiting protrusion located inside the fixing part, and the fixing part is formed with a limiting groove corresponding to the limiting protrusion.

[0010] As a further embodiment of this utility model: a second limiting spring is provided at one end of the rear terminal group facing the tongue plate, and a through groove is provided on the tongue plate. The first limiting spring and the second limiting spring are both located in the through groove, and the protrusion directions of the first limiting spring and the second limiting spring are opposite.

[0011] As a further embodiment of this utility model, the tongue plate is also provided with a plurality of second slots.

[0012] As a further embodiment of this utility model: the upper end, lower end and both sides of the metal shell are provided with third limiting spring pieces facing the tongue plate; Positioning pins are also provided on both sides of the metal casing.

[0013] Compared with the existing technology, the beneficial effects of this technical solution are as follows: the front and rear terminal groups are integrated with the core body through pre-embedded integral injection molding, which can improve the positioning accuracy of the front and rear terminal groups, avoid errors caused by manual or equipment-assisted pin assembly, resulting in misaligned pins and warping of the terminals, simplify the connector production process, and improve overall production efficiency. Furthermore, the design of a bent end at the end of the bonding piece of the front terminal group allows the bent end to be embedded in the tongue plate during injection molding to form an interlocking structure, thereby limiting the displacement of the bonding piece. This prevents the bonding piece from warping and shifting due to force during long-term insertion and removal, thus ensuring long-term stable contact between the connector and the male head and preventing transmission interruption and signal attenuation. Meanwhile, the limiting protrusion of the rear terminal group is located inside the fixing part, so that a limiting groove corresponding to the limiting protrusion is formed inside the fixing part during injection molding. The limiting protrusion forms a vertical surface that resists the impact force, thereby improving the positional stability of the rear terminal group in the core body and preventing the second welding end of the rear terminal group from loosening and causing wear during long-term insertion and removal.

[0017] 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.

[0018] Please see Figure 1-7 A USB 3.1 high-definition transmission connector includes a metal shell 1, a core body 2 installed inside the metal shell 1, and the core body 2 includes a fixing part 21 that snaps into the metal shell 1 and a tongue plate 22 for mating with a male connector. The core body 2 is provided with a front terminal group 3 and a rear terminal group 4. The front terminal group 3 and the rear terminal group 4 are respectively provided with a first welding end 31 and a second welding end 41 protruding from the rear end of the fixing part 21. The front terminal group 3 and the rear terminal group 4 are fixedly connected to the core body 2 by a pre-embedded integrated injection molding method. When assembling this connector into the circuit, the first welding end 31 and the second welding end 41 are welded and fixed to the reserved welding points on the circuit board, so that the connector can be connected into the circuit. The front terminal group 3 includes side terminals 32 located on both sides and a middle terminal 33 located between the side terminals 32. Each of the side terminals 32 and the middle terminal 33 is provided with a bonding piece 34 at one end. The bonding piece 34 is used to bond to the internal electrical contact of the male connector when the male connector is inserted to achieve an electrical connection. The end of the bonding piece 34 is provided with a bent end 35 that is embedded inside the tongue plate 22. When the external male connector is inserted into the tongue plate 22, the bonding piece 34 of the front terminal group 3 and the rear terminal group 4 make electrical contact with the male connector, thereby achieving an electrical connection between the male connector and the connector and ensuring the stability of the signal transmission process.

[0019] Specifically, the front terminal group 3 and the rear terminal group 4 are integrated with the core body 2 through pre-embedded integral injection molding, which can improve the positioning accuracy of the front terminal group 3 and the rear terminal group 4, avoid errors caused by manual or equipment-assisted pin-type assembly that result in misaligned pins and warping of the terminals, simplify the connector production process, and improve overall production efficiency. On the side terminals 32 and the middle terminals 33 of the front terminal group 3, a bonding piece 34 is provided, and a bent end 35 is designed at the end of the bonding piece 34. During injection molding, the bent end 35 is embedded in the tongue plate 22 to form an interlocking structure, thereby limiting the displacement of the bonding piece 34. This prevents the bonding piece 34 from warping and shifting due to force during long-term insertion and removal, thus ensuring long-term stable contact between the connector and the male head and preventing transmission interruption and signal attenuation.

[0020] Based on the above embodiments, it is further proposed that a groove 221 corresponding to the bonding piece 34 is formed on the bottom surface of the tongue plate 22 near the front end position, and a first slot 222 communicating with the groove 221 is formed on the top surface of the tongue plate 22 near the front end position, and the bent end 35 is fitted into the first slot 222.

[0021] Specifically, the slot 221 provides exposed space for the bonding piece 34 while restricting and fixing its position. The bent end 35 is fitted inside the first slot 222, which can strengthen the limiting of the bent end 35 and further improve the anti-lifting effect.

[0022] Based on the above embodiments, it is further proposed that the side terminal 32 has a connecting section 321 connected to the first welding end 31, and the connecting section 321 is connected to the corresponding bonding piece 34 after being bent laterally; The intermediate terminal 33 has a first limiting spring 331 that is connected to the corresponding bonding piece 34.

[0023] Specifically, after the connecting section 321 of the side terminal 32 is bent laterally, it is connected to the bonding piece 34. The angle formed by the lateral bend can further strengthen the displacement restriction of the bonding piece 34, and at the same time prevent the welding of the first welding end 31 and the welding point from becoming loose. The first limiting spring 331 of the middle terminal 33 is used to press the inserted male head.

[0024] Based on the above embodiments, it is further proposed that the rear terminal group 4 is also provided with a limiting protrusion 43 located inside the fixing part 21, and the fixing part 21 is formed with a limiting groove 211 corresponding to the limiting protrusion 43.

[0025] Specifically, when the male connector is inserted and the rear terminal group 4 is subjected to a pushing force, the limiting protrusion 43 of the rear terminal group 4 is located inside the fixing part 21, so that a limiting groove 211 corresponding to the limiting protrusion 43 is formed inside the fixing part 21 during injection molding. The limiting protrusion 43 forms a vertical surface that resists the impact force, thereby improving the positional stability of the rear terminal group 4 in the core body 2 and preventing the second welding end 41 of the rear terminal group 4 from loosening and causing wear during long-term insertion and removal.

[0026] Based on the above embodiments, it is further proposed that a second limiting spring piece 42 is provided at one end of the rear terminal group 4 facing the tongue plate 22, and a through groove 223 is provided on the tongue plate 22. The first limiting spring piece 331 and the second limiting spring piece 42 are both located in the through groove 223, and the protrusion directions of the first limiting spring piece 331 and the second limiting spring piece 42 are opposite.

[0027] Specifically, the first limiting spring 331 and the second limiting spring 42 with opposite protrusion directions can press the inserted male head on both sides, thereby improving the firmness of the insertion between the male head and the connector. The through groove 223 opened on the tongue plate 22 provides space for the elastic deformation of the first limiting spring 331 and the second limiting spring 42.

[0028] Based on the above embodiments, it is further proposed that the tongue plate 22 is also provided with a plurality of second slots 224.

[0029] Specifically, the multiple second slots 224 not only reduce the weight of the core body 2 and the amount of material used, thus reducing production costs, but also allow the positions of the multiple second slots 224 to partially correspond to the front terminal group 3 and the rear terminal group 4. During pre-embedded injection molding, positioning blocks corresponding to the multiple second slots 224 (including the first slot 222, through slot 223, and slot 221) can be set in the mold to fix the front terminal group 3 and the rear terminal group 4 in the mold in advance, so as to ensure the positional stability of the front terminal group 3 and the rear terminal group 4 during the injection molding stage and improve production accuracy.

[0030] Based on the above embodiments, it is further proposed that the metal shell 1 is provided with a third limiting spring piece 11 facing the tongue plate 22 at the upper end, lower end and both sides, for pressing the outer side of the inserted male head. The metal housing 1 is also provided with positioning pins 12 on both sides for pre-positioning during connector installation to avoid misalignment of the connector during soldering.

[0031] 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.
