[0027] Please also see Figures 1 to 3 The utility model provides a preferred embodiment of a type A USB female socket and an electronic device.

[0028] In some embodiments, as Figure 1 As shown, the present invention provides a type A USB female socket, which includes: a shell 1, a plastic part 2 and a terminal block 3; the terminal block 3 is arranged on the plastic part 2; the shell 1 is sleeved on the rear end of the plastic part 2, is engaged with the rear end of the plastic part 2, and abuts against the front end of the plastic part 2.

[0029] Specifically, the terminal row 3 has a positive terminal, a negative terminal, a D+ terminal and a D- terminal, which can realize charging function and data transmission. It should be noted that the plastic part 2 has an opening 211, and the opening 211 is used to connect with the USB male head. The end of the plastic part 2 with the opening 211 is the front end, and the end of the plastic part 2 facing away from the opening 211 is the rear end. When installing the A-type USB female socket, the terminal row 3 is inserted along the through hole at the rear end of the plastic part 2, and the rear end of the terminal row 3 is exposed outside the plastic part 2 to connect with the motherboard of the electronic device. When installing the shell 1, the shell 1 is pushed in along the rear end of the plastic part 2 and snapped with the rear end of the plastic part 2 until it abuts against the front end of the plastic part 2. In this way, after the USB female socket is installed, the shell 1 is located at the rear end of the plastic part 2. The plastic part 2 can be integrated, thereby reducing the mold opening cost of the plastic part 2 and simplifying the production process, thereby reducing costs. At the same time, the integrated design of the plastic part also enhances the product reliability of the A-type USB socket. For example, the plastic part 2 is not easy to break, and the A-type USB socket is not easy to detach.

[0030] In some embodiments, as Figure 1As shown, the plastic portion 2 includes a plastic body 21 and a tongue 22; the front end of the plastic body 21 has an opening 211; the tongue 22 is located within the plastic body 21, and one end of the tongue 22 is connected to the rear end of the plastic body 21, while the other end of the tongue 22 is suspended in the air; the front end of the terminal block 3 is disposed on the tongue 22, and the rear end of the terminal block 3 is passed through the rear end of the plastic body 21.

[0031] Specifically, the suspended end of the adhesive tongue 22 faces the opening 211 of the plastic body 21. A slot is provided on the adhesive tongue 22. The front ends of the terminals on the terminal block 3 can be accommodated in the slot to avoid short circuit. The rear end of the terminal block 3 passes through the plastic body 21 to facilitate connection with the motherboard of the electronic device.

[0032] In some embodiments, as Figure 2 and Figure 3 As shown, a first stop portion 212 is provided at the front end of the plastic body 21 , and the housing 1 abuts against the first stop portion 212 .

[0033] Specifically, the first stop portion 212 is located at the opening 211 of the USB socket. The first stop portion 212 surrounds the opening 211 of the USB socket. After the shell 1 is installed on the plastic body 21, it abuts against the first stop portion 212, and the shell 1 will not extend out of the front end of the plastic body 21.

[0034] Furthermore, a second stop portion 11 is provided at the rear end of the housing 1 , and the second stop portion 11 abuts against the rear end of the plastic body 21 .

[0035] Specifically, the second advance stop portion 11 is a spring structure, and the second advance stop portion 11 is located at the rear end of the shell 1. When the shell 1 abuts against the first advance stop portion 212, the second advance stop portion 11 also abuts against the rear end of the plastic body 21, so that the shell 1 will not move further toward the front end of the plastic body 21.

[0036] In some embodiments, as Figure 2 and Figure 3 As shown, a first stop portion 213 is provided at the front end of the plastic body 21 , and a first stop groove 12 is provided at a position of the housing 1 corresponding to the first stop portion 213 , and the first stop portion 213 is engaged with the first stop groove 12 .

[0037] Specifically, the first stop portion 213 is located on one side of the first stop portion 212. When the shell 1 abuts against the first stop portion 212, the first stop groove 12 on the shell 1 and the first stop portion 213 on the plastic body 21 are clamped together to prevent the shell 1 from loosening after being connected to the plastic body 21.

[0038] In this embodiment, a side of the first retaining portion 213 facing away from the front end of the plastic body 21 is an inclined surface, so that the housing 1 can slide into the first retaining portion 213 easily.

[0039] In some embodiments, as Figure 2 and Figure 3 As shown, the rear end of the housing 1 is provided with a second stopper 13 , and the plastic body 21 is provided with a second stopper groove 214 at a position corresponding to the second stopper 13 , and the second stopper 13 is engaged with the second stopper groove 214 .

[0040] Specifically, when the housing 1 is mounted on the plastic body 21, the second stopper 13 enters the second stopper groove 214, so that the housing 1 is not easily moved backward. In one implementation, the second stopper 13 is a spring.

[0041] In some embodiments, as Figure 2 and Figure 3 As shown, the housing 1 further includes a connecting spring 14 , which is respectively arranged on the upper end surface, the lower end surface and the side surface of the housing 1 . One end of the connecting spring 14 is suspended and penetrates the plastic body 21 .

[0042] Specifically, connecting springs 14 are respectively provided on the upper end surface, the lower end surface and the side surface of the housing 1. When the USB male plug is inserted, it can abut against the connecting springs 14, thereby enhancing the connection stability between the USB male plug and the USB female socket.

[0043] In some embodiments, the present invention further provides an electronic device comprising the above-mentioned Type A USB female socket. Specific details are as described in an embodiment of the Type A USB female socket, which will not be repeated here.

[0044] In summary, the Type A USB female socket and electronic device provided by the present invention have the following beneficial effects:

[0045] By sleeve-mounting the outer shell on the rear end of the plastic part, the outer shell is pushed in along the rear end of the plastic part during installation, so that the front end of the outer shell abuts against the front end of the plastic part. The plastic part can be integrated, thereby reducing the mold cost of the plastic part and simplifying the production process, thereby reducing costs.

[0046] At the same time, the integrated plastic design also enhances the reliability of the Type A USB socket, for example, the rubber tongue is not easy to break.

[0047] It should be understood that the application of the present invention is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
