[0002] With the increasing use of electrical appliances in offices and homes, more and more electronic products are utilizing USB ports for charging or data transmission. For example, mobile phones, laptops, mobile power adapters, and car chargers all require USB receptacles for charging or data transmission. For mobile power adapters and car chargers, after assembling the USB receptacle within the housing, the cover must be ultrasonically welded to the housing to achieve waterproofing.

[0003] In the prior art, a USB socket mainly includes an insulating rubber core, a metal shielding shell installed in the insulating rubber core, and conductive terminals fixed on the insulating rubber core. The conductive terminals are welded to the PCB board of the electronic product to realize electrical signal or data transmission. When the USB socket is assembled into an electronic product, the conductive terminals of the USB socket are first welded to the PCB board of the electronic product, and then the USB socket and the PCB board are installed inside the shell of the electronic product. The surface cover of the electronic product is then assembled with the USB socket, and the surface cover and the shell are ultrasonically welded to encapsulate the USB socket. However, since the surface cover will cause the conductive terminals of the USB socket to be directly subjected to ultrasonic vibration during the ultrasonic welding process, it is easy to cause the conductive terminals on the USB socket and the PCB board to become loose, resulting in a low yield rate of electronic products assembled with the USB socket. Summary of the Invention

[0026] Please refer to Figures 1-6 The embodiment of the present invention provides a split USB female socket, comprising:

[0027] The soldering base 1 includes a base body 11, a plurality of first elastic conductive terminals 12 disposed on the base body 11 and used for soldering to a PCB board 100 of an electronic product, and a first buckling portion 111 is provided on the base body 11;

The USB body 2 and the soldering socket 1 are fastened to each other via the first fastening portion 111 and the second fastening portion 2111. One end of each second elastic conductive terminal 23 is fixed to the tongue plate 212, and the other end passes through the insulating shell 211 and elastically contacts the corresponding first elastic conductive terminal 12.

[0029] In the embodiment of the present invention, the electronic product may be an electronic product with a USB socket, such as a mobile phone power adapter and a car charger.

[0030] In the embodiment of the present invention, the number of first elastic conductive terminals 12 is four, and the number of second elastic conductive terminals 23 is also four. Furthermore, the number of first elastic conductive terminals 12 and second elastic conductive terminals 23 can be set to other numbers according to actual needs. Both the first elastic conductive terminals 12 and the second elastic conductive terminals 23 are metal conductive terminals.

[0031] As an embodiment of the present invention, each first elastic conductive terminal 12 includes a solder foot 121 for soldering to the PCB board 100 and a conductive portion 122 connected to the solder foot 121. The conductive portion 122 is provided with a plurality of protrusions 1221 that contact the corresponding second elastic conductive terminal 23.

[0032] In this embodiment, the first elastic conductive terminal 12 utilizes the plurality of protrusions 1221 to form contact with the second elastic conductive terminal 23 , so that stable electrical signal and data transmission is maintained between the first elastic conductive terminal 12 and the second elastic conductive terminal 23 .

[0033] As one embodiment of the present invention, the base 11 is provided with a plurality of positioning holes 112 and a plurality of positioning slots 113 that match the number of first elastic conductive terminals 12. The solder leg 121 of each first elastic conductive terminal 12 passes through a positioning hole 112 and is soldered to the PCB 100, and the conductive portion 122 of each first elastic conductive terminal 12 is received within a positioning slot 113. In this embodiment, there are four positioning holes 112 and four positioning slots 113.

[0034] In this embodiment, the positioning hole 112 is used to limit the soldering foot 121 of the first elastic conductive terminal 12 to prevent the soldering foot 121 from shifting, so that the soldering foot 121 and the PCB board 100 are more firmly welded; at the same time, the positioning groove 113 is used to limit the conductive part 122, so that the conductive part 122 and the second elastic conductive terminal 23 maintain a more stable contact.

[0035] As an embodiment of the present invention, the first buckling portion 111 is a buckling platform protruding from the base 11 , and the second buckling portion 2111 is a sliding groove matched with the buckling platform.

[0036] In this embodiment, the USB body 2 and the soldering base 1 are connected by interlocking a latching plate and a sliding groove. When assembling the USB body 2 and the soldering base 1, the sliding groove on the USB body 2 is aligned with the latching plate on the soldering base 1, and the USB body 2 is slid relative to the soldering base 1 to achieve interlocking engagement between the latching plate and the sliding groove. This slidable engagement of the latching plate and the sliding groove allows for easy and convenient operation, facilitating the interlocking operation of the USB body 2 and the soldering base 1.

[0037] In another embodiment, the first buckling portion 111 may also be a sliding groove, and the second buckling portion 2111 is a buckling platform buckled with the sliding groove.

[0038] As an embodiment of the present invention, the buckle platform is an L-shaped boss, and the slide groove is an L-shaped groove. The L-shaped boss and the L-shaped groove cooperate to achieve a sliding buckle between the USB body 2 and the welding seat 1, making the buckle between the USB body 2 and the welding seat 1 stable and reliable, and easy to operate.

[0039] As an embodiment of the present invention, a first buckling portion 111 is provided on both sides of the base 11 , and a second buckling portion 2111 is provided on both sides of the insulating shell 211 . Each first buckling portion 111 is buckled with the corresponding second buckling portion 2111 .

[0040] Specifically, a buckle platform is provided on both sides of the seat body 11, and a slide groove is provided on both sides of the insulating shell 211. Each buckle platform is engaged with the corresponding slide groove, so that the engagement between the USB body 2 and the welding seat 1 is more stable and reliable, and the sliding of the USB body 2 relative to the welding seat 1 is more stable.

[0041] In an embodiment of the present invention, the split USB socket is provided with a split welding socket 1 and a USB body 2. When the split USB socket is assembled into an electronic product, the split USB socket can be assembled in steps. Specifically, when the USB socket is assembled into an electronic product, the first conductive terminal 12 on the welding socket 1 can be welded to the PCB board 100 of the electronic product to fix the welding socket 1 to the PCB board 100. Then, the welding socket 1 and the PCB board 100 can be installed inside the housing of the electronic product. The insulating rubber core 21 of the USB body 2 can be fixed to the cover of the electronic product. Then, the second snap-fitting portion 2111 on the USB body 2 can be snap-fitted to the first snap-fitting portion 111 on the welding socket 1 to form a snap fit between the USB body 2 and the welding socket 1. The second elastic conductive terminal 23 on the USB body 2 can be elastically contacted with the corresponding first elastic conductive terminal 12 on the welding socket 1 to achieve electrical signal and data transmission. At the same time, the cover of the electronic product can be placed on the housing of the electronic product. Finally, the cover and the housing of the electronic product are ultrasonically welded to encapsulate the USB socket.

[0042] In the embodiment of the present invention, since the first elastic conductive terminal 12 and the second elastic conductive terminal 23 on the welding seat 1 are in elastic contact to avoid hard contact, the first elastic conductive terminal 12 on the welding seat 1 will not be directly affected by the vibration of the ultrasonic wave, thereby preventing the first elastic conductive terminal 12 and the PCB board 100 from becoming loose. In addition, the elastic contact between the first elastic conductive terminal 12 and the second elastic conductive terminal 23 can maintain stable electrical signals and data transmission, thereby improving the yield rate of electronic products assembled with the USB female socket.

[0044] In this embodiment, a sealing ring 24 is provided on the insulating shell 211 surrounding the opening 2110. After the USB body 2 is assembled with the cover of the electronic product, the sealing ring 24 is used to seal the gap between the insulating shell 211 and the cover, thereby improving the waterproof effect and preventing water from entering the interior of the electronic product from between the insulating shell 211 and the cover of the electronic product.

[0046] In this embodiment, a threaded hole 2113 is provided on the insulating shell 211, and the threaded hole 2113 is used to fix the insulating shell 211 of the USB body 2 to the surface cover through screws, so that the sealing ring 24 is stably fixed between the insulating shell 211 and the surface cover, preventing the sealing ring 24 from loosening during the subsequent assembly process of the USB body 2, thereby maintaining a good waterproof effect.

[0047] In this embodiment, when the USB female socket is assembled into an electronic product, the first conductive terminal 12 on the welding seat 1 can be welded to the PCB board 100 of the electronic product first to weld and fix the welding seat 1 to the PCB board 100, and then the welding seat 1 together with the PCB board 100 can be installed inside the shell of the electronic product, and then the surface cover of the electronic product and the USB body 2 are assembled into one through the threaded holes and screws, and then the USB body 2 is slidably buckled on the welding seat 1, so that the second elastic conductive terminal 23 on the USB body 2 is in elastic contact with the corresponding first elastic conductive terminal 12 on the welding seat 1 to realize electrical signal and data transmission, and at the same time, the surface cover of the electronic product is covered with the shell of the electronic product, and then the surface cover and the shell are ultrasonically welded. Since the USB body 2 is fixed to the cover by screws, the sealing ring 24 is stably fixed between the insulating shell 211 and the cover, preventing the sealing ring 24 from loosening during the subsequent ultrasonic welding process of the cover assembly, thereby maintaining a good waterproof effect; at the same time, the elastic contact between the first elastic conductive terminal 12 and the second elastic conductive terminal 23 can avoid loosening of the welding between the first elastic conductive terminal 12 and the PCB board 100, thereby improving the yield rate of electronic products assembled with the USB socket.

[0048] As an embodiment of the present invention, a fixing portion 2112 is provided at a diagonal position of one end of the insulating shell 211 fixed to the surface cover, and each fixing portion 2112 is provided with a threaded hole 2113 .

[0049] In this embodiment, the insulating housing 211 utilizes two threaded holes 2113 to respectively cooperate with screws to fix the USB body 2 on the cover, so that the USB body 2 and the cover are fixed more firmly.

[0050] As an embodiment of the present invention, the USB body 2 further includes an insulating member 25 fixed in the receiving cavity, and the plurality of second elastic conductive terminals 23 and the insulating member 25 are integrally injection-molded.

The sealing cover plate 26 is provided with a through hole 261, through which one end of the second elastic conductive terminal 23 extends. The sealing cover plate 26 seals the rear end of the insulating housing 211, providing a good sealing effect for the insulating housing 211, and can also be used to secure the second elastic conductive terminal 23 in place.

[0053] As an embodiment of the present invention, the welding seat 1 further includes a metal welding piece 13 . The metal welding piece 13 passes through the seat body 11 and is welded to the PCB board 100 to fix the seat body 11 on the PCB board 100 .

[0057] The threaded hole 2113 on the USB body 2 is connected to the cover via screws, allowing the sealing ring 24 on the USB body 2 to be stably fixed between the insulating housing 211 and the cover, thereby maintaining a good waterproof effect between the split USB socket and the cover. The electronic product provided in this embodiment, by providing the above-mentioned split USB socket, can prevent the problem of loose soldering between the USB socket and the PCB board during the assembly process of the electronic product, while maintaining a good waterproof effect between the split USB socket and the cover, thereby greatly improving the yield rate of the electronic product.
