[0046] Please also see Figures 1 to 4 The utility model provides a preferred embodiment of a horizontal Type-A female socket.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, the present invention provides a horizontal Type-A female connector, which includes: an outer shell 1, an inner shell 2, a plastic body 3, and a terminal block 4. The outer shell 1 is disposed outside the plastic body 3; the inner shell 2 is disposed inside the plastic body 3; the terminal block 4 is mounted on the plastic body 3; and the outer shell 1 is connected to a ground terminal and to the inner shell 2.

[0048] Specifically, the horizontal Type-A socket is a 4PIN horizontal Type-A socket, and the terminal row 4 is inserted into the plastic body 3. The terminal row 4 is L-shaped, and the terminal row 4 is divided into a front end and a rear end. The front end of the terminal row 4 is located in the cavity formed by the inner shell 2 and the plastic body 3, and the rear end of the terminal row 4 is connected to the circuit board, and the inner shell 2 is covered by the front end of the terminal row 4. The outer shell 1 is covered on the periphery of the plastic body 3 and connected to the inner shell 2, wherein the outer shell 1 is connected to the ground end of the circuit board to achieve grounding, so that the inner shell 2 is also grounded. In this way, the utility model can improve the electromagnetic shielding effect of the horizontal Type-A socket by connecting the inner shell 2 of the horizontal Type-A socket to the outer shell 1 and grounding, thereby reducing the impact of electromagnetic waves on data transmission.

[0049] In this embodiment, the terminal block 4 includes a positive terminal, a negative terminal and a data transmission terminal, wherein the data transmission terminal includes a D+ terminal and a D- terminal to realize data transmission, and the positive terminal and the negative terminal can realize the charging function.

[0050] In some embodiments, as Figures 1 to 3 As shown, the shell 1 includes pins 11 and a first limiting portion 12; wherein, the pins 11 are distributed at the bottom of both sides of the shell 1, and the pins 11 are used to connect to the circuit board and achieve grounding; the first limiting portion 12 is arranged on the back side of the shell 1 and is connected to the inner shell 2.

[0051] Furthermore, the inner shell 2 includes a fourth limiting portion 21 ; the fourth limiting portion 21 is disposed through the plastic body 3 and connected to the first limiting portion 12 .

[0052] Specifically, the outer shell 1 has at least two pins 11, which are located on both sides of the outer shell 1. The pins 11 can achieve grounding after being connected to the circuit board. The first stopper 12 is located on both sides of the rear end of the outer shell 1 and can block the plastic body 3 and prevent it from shifting backward. The fourth stopper 21 is located on both sides of the inner shell 2. The fourth stopper 21 is provided through the plastic body 3 and abuts the first stopper 12, thereby achieving grounding through the first stopper 12.

[0053] In some embodiments, as Figures 1 to 4 As shown, the plastic body 3 includes a plastic body 31, a tongue plate 32, a first accommodating cavity 33, and a second accommodating cavity 34. The tongue plate 32 is provided on the plastic body 31; the first accommodating cavity 33 is located at the bottom of the tongue plate 32 and is used to accommodate the front end of the terminal block 4; the second accommodating cavity 34 is provided on the back of the plastic body 3 and is used to accommodate the rear end of the terminal block 4.

[0054] Specifically, the tongue plate 32 provides support when the Type-A female connector is connected to the Type-A male connector. Because the terminals of the terminal block 4 are L-shaped, when the terminal block 4 is assembled, the front ends of the terminals can be accommodated in the first accommodating cavity 33, while the rear ends of the terminals are accommodated in the second accommodating cavity 34. This not only improves the stability of the terminal block 4, but also isolates the terminals to prevent short circuits between them.

[0055] In some embodiments, as Figures 1 to 3 As shown, the housing 1 further includes a second limiting portion 13 and a third limiting portion 14; wherein, the second limiting portion 13 is located at the top of the housing 1 and is clamped with the plastic body 3; the third limiting portion 14 is located on both sides of the top of the housing 1 and is clamped with the plastic body 3.

[0056] Furthermore, the plastic body 3 includes a first limiting groove 35 and a second limiting groove 36. The first limiting groove 35 is located at the top of the plastic body 3 and is arranged opposite to the second limiting portion 13; the second limiting groove 36 is located on both sides of the top of the plastic body 3 and is arranged opposite to the third limiting portion 14.

[0057] Specifically, the second limiting portion 13 is a spring structure and is located at the top of the housing 1, while the third limiting portions 14 are located on both sides of the top of the housing 1. When the housing 1 is assembled on the plastic body 3, the second limiting portion 13 engages with the first limiting groove 35, and the third limiting portion 14 engages with the second limiting groove 36, thereby ensuring a stable installation of the housing 1 and the plastic body 3.

[0058] In some embodiments, as Figures 1 to 3 As shown, the plastic body 3 further includes a fifth limiting portion 37 , which is located at the bottom of the plastic body 3 and forms a gap with the plastic body 31 , and the pin 11 is clamped in the gap.

[0059] Specifically, the fifth limiting portions 37 are located on both sides of the plastic body 3 and can respectively clamp the pins 11 on both sides of the housing 1 to prevent the pins 11 from shaking.

[0060] In some embodiments, as Figure 2 and Figure 3 As shown, the inner shell 2 further includes a first elastic piece 22, a second elastic piece 23, and a third elastic piece 24. The first elastic piece 22 is relatively arranged on the upper end surface of the inner shell 2; the second elastic piece 23 is relatively arranged on the lower end surface of the inner shell 2; and the third elastic piece 24 is located on both sides of the inner shell 2.

[0061] Specifically, the first spring clip 22 and the second spring clip 23 are located on the upper and lower end surfaces of the inner shell 2, respectively, and the third spring clip 24 is located on both side surfaces of the inner shell. The plastic body 3 is provided with retaining holes adapted to the first spring clip 22, the second spring clip 23, and the third spring clip 24. When a Type-A male connector is connected to a Type-A female connector, the first spring clip 22, the second spring clip 23, and the third spring clip 24 cooperate with the Type-A male connector to achieve a stable connection.

[0062] In some embodiments, as Figure 1 and Figure 4 As shown, a clearance cavity 38 is provided at the bottom of the plastic body 3 , and the clearance cavity 38 can provide a clearance space for some components on the circuit board.

[0063] In some embodiments, as Figure 1 and Figure 3 As shown, the horizontal Type-A female socket further includes a waterproof plate 5 , which is located on the back of the plastic body 3 ; the terminal block 4 is passed through the waterproof plate 5 .

[0064] Specifically, because the terminal block 4 is inserted through the plastic body 3 and is assembled with the plastic body 3, a gap exists between the terminal block 4 and the plastic body 3. In this embodiment, the terminal block 4 and the waterproof plate 5 are integrally formed, and the waterproof plate 5 and the plastic body 3 are connected by a hard interference. When the terminal block 4 is installed on the plastic body 3, the waterproof plate 5 can seal the gap between the terminal block 4 and the plastic body 3, thereby achieving a waterproof effect.

[0065] In summary, the horizontal Type-A female socket provided by the present invention has the following beneficial effects:

[0066] By grounding the inner and outer shells of the horizontal Type-A female connector, the electromagnetic shielding effect of the horizontal Type-A female connector can be improved, thereby reducing the impact of electromagnetic waves on data transmission;

[0067] The waterproof plate can seal the gap between the terminal block and the plastic body, thereby achieving a waterproof effect.
