USB board connector

Abstract

A USB board-side connector provides shielded chambers for multiple high-speed signal terminal pairs and low-speed signal terminal pairs respectively, thereby reducing the radiated interference of the high-speed signals of the multiple high-speed signal terminal pairs and the low-speed signals of the low-speed signal terminal pairs to an acceptable range. In this way, it can effectively suppress the radiated interference between low-speed signals and high-speed signals, and also effectively suppress the radiated interference between the high-speed signals of multiple high-speed signal terminal pairs. This reduces the degree of attenuation and distortion of low-speed and high-speed signals in the USB board-side connector during transmission, thus meeting the signal transmission requirements for low-speed and high-speed signals in the USB board-side connector specification.

Description

Technical Field

[0001] This application relates to signal transmission technology, and more specifically, to a USB board-side connector that can meet the signal transmission requirements for low-speed and high-speed signals in the USB connector specification. Background Technology

[0002] USB connectors are widely used in various electronic devices for signal transmission. With the advancement of technology, the demand for USB connector signal transmission is increasing day by day. Therefore, in recent years, in addition to transmitting low-speed signals, USB connectors have also been required to transmit high-speed signals. In the USB 3.2 connector specification, the transmission rate of high-speed signals has developed from 5Gbps in Gen1 to 20Gbps in Gen2*2. In the USB 4 connector specification, the transmission rate of high-speed signals is required to reach 40Gbps.

[0003] However, existing USB connectors suffer from inadequate shielding due to their mechanical design, leading to frequent radiated interference between high-speed and low-speed signals. This causes attenuation and distortion of both signals during transmission, making it difficult to meet the signal transmission requirements for both high and low speeds specified in the USB connector standard. Therefore, preventing radiated interference during signal transmission is a primary technical challenge in USB connector design. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the main purpose of this application is to reduce the radiated interference between high-speed and low-speed signals in the USB board connector, as well as the radiated interference between high-speed signals of multiple high-speed signal terminal pairs, to an acceptable range, so as to meet the signal transmission requirements for low-speed and high-speed signals in the USB connector specification.

A high-speed signal shielding structure is provided at the bottom left, which overlaps with the intermediate transverse spacer to form a high-speed signal shielding chamber at the bottom left. At least one portion of the high-speed signal terminal pair at the bottom left is located within the high-speed signal shielding chamber, thereby shielding the high-speed signal from the top right, the top left, the top low-speed signal, the bottom low-speed signal, or the high-speed signal at the bottom right.

A bottom low-speed signal shielding structure is provided, which overlaps the intermediate transverse spacer to form a bottom low-speed signal shielding chamber.

[0071] The following describes several embodiments of this application. In these embodiments, identical or similar components are designated by the same symbols, and identical or similar technical features will be omitted from the description:

[0072] First Embodiment

[0073] In this application, as Figures 12 to 15 As shown, the USB board connector 1 is used in conjunction with the circuit board 2 to transmit high-speed signals and low-speed signals. Specifically, as...

However, the components of the USB board connector 1 may also omit at least one of them or add other components depending on the actual use, and are not limited to the above.

[0075] Additionally, the bottom terminal group 12 includes a left bottom high-speed signal terminal pair 121 for transmitting a left bottom high-speed signal, a bottom low-speed signal terminal pair 122 for transmitting a bottom low-speed signal, and a right bottom high-speed signal terminal pair 123 for transmitting a right bottom high-speed signal, wherein the bottom low-speed signal terminal pair 122 is located between the left bottom high-speed signal terminal pair 121 and the right bottom high-speed signal terminal pair 123.

[0076] like Figures 2 to 3As shown, the intermediate transverse spacer 13 is located between the top terminal group 11 and the bottom terminal group 12 to separate the top terminal group 11 and the bottom terminal group 12, thereby reducing the electromagnetic field and other radiation interference between the top terminal group 11 and the bottom terminal group 12 to an acceptable range.

[0077] like Figures 4 to 5 As shown, the USB board connector 1 may include a first top shielding housing B1, a first bottom shielding housing B2, a second top shielding housing B3, and a second bottom shielding housing B4 for providing shielding.

[0078] like Figure 13 As shown, the second top shielding shell B3 overlaps the first top shielding shell B1 to form a left top high-speed signal shielding structure 141. The left top high-speed signal shielding structure 141 overlaps the intermediate transverse spacer 13 to form a left top high-speed signal shielding chamber E1. At least one portion of the left top high-speed signal terminal pair 111 is located inside the left top high-speed signal shielding chamber E1. It should be noted that the left top high-speed signal shielding chamber E1 provides a shielding environment for at least one portion of the left top high-speed signal terminal pair 113, isolating electromagnetic fields and other interference sources outside the left top high-speed signal shielding chamber E1, so that the electromagnetic field and other radiated interference generated by the left top high-speed signal, right top high-speed signal, left bottom high-speed signal, bottom low-speed signal, right bottom high-speed signal, or other signals on the top low-speed signal is reduced to an acceptable range.

[0079] like Figure 13 As shown, the first top shielding housing B1 forms the first part of the top low-speed signal shielding structure 142. Figure 14 As shown, the second top shielding shell B3 overlaps the first top shielding shell B1 to form the second part of the top low-speed signal shielding structure 142. The top low-speed signal shielding structure 142 overlaps the intermediate transverse spacer 13 to form the top low-speed signal shielding chamber E2. At least one portion of the top low-speed signal terminal pair 112 is located within the top low-speed signal shielding chamber E2. It should be noted that the top low-speed signal shielding chamber E2 provides a shielding environment for at least one portion of the top low-speed signal terminal pair 112, isolating electromagnetic fields and other interference sources outside the top low-speed signal shielding chamber E2, so that electromagnetic field and other radiated interference generated by the left top high-speed signal, right top high-speed signal, left bottom high-speed signal, bottom low-speed signal, right bottom high-speed signal, or other signals on the top low-speed signal is reduced to an acceptable range.

At least one portion of the right top high-speed signal terminal pair 113 is located in the right top high-speed signal shielding chamber E3. It should be noted that the right top high-speed signal shielding chamber E3 provides a shielding environment for at least one portion of the right top high-speed signal terminal pair 113, isolating electromagnetic fields and other interference sources outside the right top high-speed signal shielding chamber E3, so that the electromagnetic field and other radiation interference generated by the left top high-speed signal, right top high-speed signal, left bottom high-speed signal, bottom low-speed signal, right bottom high-speed signal, or other signals on the top low-speed signal is reduced to an acceptable range.

[0081] In addition, such as Figure 4 As shown, the USB board connector 1 may include a top shielding cover 161, wherein a first top shielding housing B1 is formed by the top shielding cover 161. The top shielding cover 161 is bent to form a left top flap 1411 located between the left top high-speed signal terminal pair 111 and the top low-speed signal terminal pair 112, so that the left top flap 1411 provides isolation between the left top high-speed signal terminal pair 111 and the top low-speed signal terminal pair 112, thereby reducing the radiated interference between the left top high-speed signal and the top low-speed signal to an acceptable range. The top shielding cover 161 may also be bent to form a right top flap 1431 located between the right top high-speed signal terminal pair 113 and the top low-speed signal terminal pair 112, so that the right top flap 1431 provides isolation between the right top high-speed signal terminal pair 113 and the top low-speed signal terminal pair 112, thereby reducing the radiated interference between the right top high-speed signal and the top low-speed signal to an acceptable range.

[0082] like Figure 10 As shown, the left top high-speed signal terminal pair 111, the top low-speed signal terminal pair 112, and the right top high-speed signal terminal pair 113 respectively have left top high-speed signal pin pair 1111, top low-speed signal pin pair 1121, and right top high-speed signal pin pair 1131 for connecting to the circuit board 2. The left top flap 1411 extends between the left top high-speed signal pin pair 1111 and the top low-speed signal pin pair 1121, and is used to connect to the circuit board 2 to provide shielding against radiation generated by the left top high-speed signal or the top low-speed signal, reducing the radiated interference between the left top high-speed signal and the top low-speed signal to an acceptable level. The right top flap 1431 extends between the right top high-speed signal pin pair 1131 and the top low-speed signal pin pair 1121, and is used to connect to the circuit board 2 to provide shielding against radiation generated by the right top high-speed signal or the top low-speed signal, reducing the radiated interference between the right top high-speed signal and the top low-speed signal to an acceptable level.

[0083] like Figure 13 As shown, the second bottom shielding shell B4 overlaps the first bottom shielding shell B2 to form a left bottom high-speed signal shielding structure 144. The left bottom high-speed signal shielding structure 144 overlaps the intermediate transverse spacer 13 to form a left bottom high-speed signal shielding chamber E4. At least one portion of the left bottom high-speed signal terminal pair 121 is located inside the left bottom high-speed signal shielding chamber E4. It should be noted that the left bottom high-speed signal shielding chamber E4 provides a shielding environment for at least one portion of the left bottom high-speed signal terminal pair 121, isolating electromagnetic fields and other interference sources outside the left bottom high-speed signal shielding chamber E4, so that the electromagnetic field and other radiated interference generated by the right top high-speed signal, left top high-speed signal, top low-speed signal, bottom low-speed signal, right bottom high-speed signal, or other signals on the left bottom high-speed signal is reduced to an acceptable range.

[0084] like Figure 13 As shown, the first bottom shielding housing B2 forms the first part of the bottom low-speed signal shielding structure 145.

The bottom low-speed signal shielding structure 145 overlaps the intermediate transverse spacer 13 to form the bottom low-speed signal shielding chamber E5. At least one portion of the bottom low-speed signal terminal pair 122 is located within the bottom low-speed signal shielding chamber E5. It should be noted that the bottom low-speed signal shielding chamber E5 provides a shielding environment for at least one portion of the bottom low-speed signal terminal pair 122, isolating electromagnetic fields and other interference sources outside the bottom low-speed signal shielding chamber E5, so that the electromagnetic field and other radiated interference generated by the left top high-speed signal, the top low-speed signal, the right top high-speed signal, the left bottom high-speed signal, the right bottom high-speed signal, or other signals on the bottom low-speed signal is reduced to an acceptable range.

[0085] like Figure 13 As shown, the second bottom shielding shell B4 overlaps the first bottom shielding shell B2 to form a right bottom high-speed signal shielding structure 146. The right bottom high-speed signal shielding structure 146 overlaps the intermediate transverse spacer 13 to form a right bottom high-speed signal shielding chamber E6. At least one portion of the right bottom high-speed signal terminal pair 123 is located within the right bottom high-speed signal shielding chamber E6. It should be noted that the right bottom high-speed signal shielding chamber E6 provides a shielding environment for at least one portion of the right bottom high-speed signal terminal pair 123, isolating electromagnetic fields and other interference sources outside the right bottom high-speed signal shielding chamber E6, so that electromagnetic field and other radiated interference generated by the left top high-speed signal, right top high-speed signal, top low-speed signal, left bottom high-speed signal, bottom low-speed signal, or other signals on the right bottom high-speed signal is reduced to an acceptable range.

[0086] In addition, such as Figure 4As shown, the USB board-side connector 1 may include a bottom shielding cover 162, wherein the first bottom shielding housing B2 is formed by the bottom shielding cover 162. The bottom shielding cover 162 forms a left bottom flap 1441 located between the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122 by bending, thereby separating the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122 and reducing the radiated interference between the left bottom high-speed signal and the bottom low-speed signal to an acceptable level. The bottom shielding cover 162 also forms a right bottom flap 1461 located between the right bottom high-speed signal terminal pair 123 and the bottom low-speed signal terminal pair 122 by bending, thereby separating the right bottom high-speed signal terminal pair 123 and the bottom low-speed signal terminal pair 122 and reducing the radiated interference between the right bottom high-speed signal and the bottom low-speed signal to an acceptable level.

The left bottom flap 1441 extends between the left bottom high-speed signal pin pair 1211 and the bottom low-speed signal pin pair 1221, and is used to connect to the circuit board 2 to provide shielding against radiation generated by the left bottom high-speed signal or the bottom low-speed signal, reducing the radiated interference between the left bottom high-speed signal and the bottom low-speed signal to an acceptable level. The right bottom flap 1461 extends between the right bottom high-speed signal pin pair 1231 and the bottom low-speed signal pin pair 1221, and is used to connect to the circuit board 2 to provide shielding against radiation generated by the right bottom high-speed signal or the bottom low-speed signal, reducing the radiated interference between the right bottom high-speed signal and the bottom low-speed signal to an acceptable level.

[0088] For information on the manufacturing of the connector in this embodiment, please refer to [link / reference]. Figures 1 to 12 This embodiment of the connector is illustrated in the main manufacturing process diagram. Figures 1 to 3 As shown, firstly, a middle transverse spacer 13, a top terminal group 11, and a bottom terminal group 12 are prepared, and the top terminal group 11 and the bottom terminal group 12 are respectively assembled above and below the middle transverse spacer 13 to form a first connector semi-finished product. Next, as... Figures 4 to 8 as well as Figures 13 to 14As shown, multiple first top shielding shells B1, first bottom shielding shells B2, second top shielding shells B3, and second bottom shielding shells B4 are prepared respectively. The first top shielding shells B1 and B3 are sequentially assembled on top of the first connector semi-finished product. The first top shielding shell B1 forms the first part of the top low-speed signal shielding structure 142. The combination of the first top shielding shell B1 and the second top shielding shell B3 forms the left top high-speed signal shielding structure 141, the second part of the top low-speed signal shielding structure 142, and the right top high-speed signal shielding structure 143. In addition, the first bottom shielding shells B2 and B4 are sequentially assembled on the bottom of the first connector semi-finished product. The first bottom shielding shell B2 forms the first part of the bottom low-speed signal shielding structure 145. The combination of the first bottom shielding shell B2 and the second bottom shielding shell B4 forms the left bottom high-speed signal shielding structure 144, the second part of the bottom low-speed signal shielding structure 145, and the right bottom high-speed signal shielding structure 146. In this way, the second connector semi-finished product can be constructed.

[0089] Then, as Figures 11 to 12 As shown, a metal shell 15 is fitted onto the second connector semi-finished product. The metal shell 15 shields the top terminal group 11 and bottom terminal group 12 from external electromagnetic interference, reducing external interference to the left top high-speed signal, top low-speed signal, right top high-speed signal, left bottom high-speed signal, bottom low-speed signal, and right bottom high-speed signal to an acceptable range. Additionally, as... Figure 15 As shown, the metal casing 15 is electrically connected to the intermediate transverse spacer 13, thereby electrically connecting the left top high-speed signal shielding structure 141, the top low-speed signal shielding structure 142, the right top high-speed signal shielding structure 143, the left bottom high-speed signal shielding structure 144, the bottom low-speed signal shielding structure 145, the right bottom high-speed signal shielding structure 146, and the intermediate transverse spacer 13 to form a shielded loop for transmitting shielded signals. In this way, the metal casing 15 can provide shielding for the top terminal group 11 and the bottom terminal group 12, so that external interference to the left top high-speed signal, the top low-speed signal, the right top high-speed signal, the left bottom high-speed signal, the bottom low-speed signal, and the right bottom high-speed signal is reduced to an acceptable range. It should be noted that the high-speed signal shielding structure 141 on the top left and the high-speed signal shielding structure 143 on the top right are not limited to the first top shielding shell B1 and can also be constructed by multiple metal plates; the high-speed signal shielding structure 144 on the bottom left and the high-speed signal shielding structure 146 on the bottom right are not limited to the first bottom shielding shell B2 and can also be constructed by multiple metal plates.

[0090] In addition, such as Figure 4As shown, the intermediate transverse spacer 13 between the top terminal group 11 and the bottom terminal group 12 has, for example, a left top strong coupling structure 131, a right top strong coupling structure 132, a left bottom strong coupling structure 133, and a right bottom strong coupling structure 134, which are formed by concave and convex structures. The left top strong coupling structure 131 is located between the left top high-speed signal terminal pair 111 and the top low-speed signal terminal pair 112 to provide a strong coupling effect and reduce mutual interference between the left top high-speed signal and the top low-speed signal. The right top strong coupling structure 132 is located between the top low-speed signal terminal pair 112 and the right top high-speed signal terminal pair 113 to provide a strong coupling effect and reduce mutual interference between the top low-speed signal and the right top high-speed signal. The left bottom strong coupling structure 133 is located between the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122 to provide a strong coupling effect and reduce mutual interference between the left bottom high-speed signal and the bottom low-speed signal. The bottom right strong coupling structure 134 is located between the bottom low-speed signal terminal pair 122 and the bottom right high-speed signal terminal pair 123 to provide a strong coupling effect and reduce mutual interference between the bottom low-speed signal and the bottom right high-speed signal.

[0091] Specifically, such as Figure 1 As shown, the middle transverse spacer 13 also includes a top spacer 135 and a bottom spacer 136, while the left top strong coupling structure 131 and the right top strong coupling structure 132 are disposed on the top spacer 135, and the left bottom strong coupling structure 133 and the right bottom strong coupling structure 134 are disposed on the bottom spacer 136.

[0092] Second Embodiment

[0093] like Figures 17 to 27 As shown, the USB board connector 1 is used in conjunction with the circuit board 2 to transmit high-speed signals and low-speed signals, and the components may include a top terminal group 11, a bottom terminal group 12, a middle lateral spacer 13, a top shielding cover 161, a bottom shielding cover 162, a left longitudinal partition 163, and a right longitudinal partition 164.

[0094] like Figures 20 to 22 As shown, the left longitudinal partition 163 and the right longitudinal partition 164 are respectively joined to the intermediate transverse spacer 13 by, for example, plug-in connection, and are matched with the top shielding cover 161 and the bottom shielding cover 162 to form the left top high-speed signal shielding chamber E1, the top low-speed signal shielding chamber E2, the right top high-speed signal shielding chamber E3, the left bottom high-speed signal shielding chamber E4, the bottom low-speed signal shielding chamber E5, and the right bottom high-speed signal shielding chamber E6 as described in the first embodiment. In this embodiment, the left longitudinal partition 163 includes the left top wing 1411 or the left bottom wing 1441 as described in the first embodiment, and the right longitudinal partition 164 includes the right top wing 1431 or the right bottom wing 1461 as described in the first embodiment.

[0095] For information on the manufacturing of the connector in this embodiment, please refer to [link / reference]. Figures 18 to 27 This embodiment of the connector is illustrated in the main manufacturing process diagram. Figures 18 to 19 As shown, firstly, a middle transverse spacer 13, a top terminal group 11, and a bottom terminal group 12 are prepared, and the top terminal group 11 and the bottom terminal group 12 are respectively assembled above and below the middle transverse spacer 13 to form a first connector semi-finished product. Next, as... Figures 20 to 21 As shown, a top shielding cover 161, a bottom shielding cover 162, a left longitudinal partition 163, and a right longitudinal partition 164 are prepared respectively. The left longitudinal partition 163 and the right longitudinal partition 164 are joined with the intermediate transverse spacer 13. Then, the top shielding cover 161 and the bottom shielding cover 162 are assembled above and below the first connector semi-finished product to form a left top high-speed signal shielding chamber E1, a top low-speed signal shielding chamber E2, a right top high-speed signal shielding chamber E3, a left bottom high-speed signal shielding chamber E4, a bottom low-speed signal shielding chamber E5, and a right bottom high-speed signal shielding chamber E6, respectively, thus constituting the second connector semi-finished product.

[0096] Then, as Figures 25 to 26 As shown, a metal housing 15 is fitted onto the second connector semi-finished product, and the metal housing 15 is electrically in contact with the top shielding cover 161 and the bottom shielding cover 162, so that the metal housing 15 is electrically connected to the left top high-speed signal shielding chamber E1, the top low-speed signal shielding chamber E2, the right top high-speed signal shielding chamber E3, the left bottom high-speed signal shielding chamber E4, the bottom low-speed signal shielding chamber E5, and the right bottom high-speed signal shielding chamber E6 to form a shielding circuit. In this way, the metal housing 15 can provide shielding for the top terminal group 11 and the bottom terminal group 12, so that the external interference to the left top high-speed signal, the top low-speed signal, the right top high-speed signal, the left bottom high-speed signal, the bottom low-speed signal, and the right bottom high-speed signal is reduced to an acceptable range.

[0097] In summary, the USB board connector of this application provides shielded chambers for multiple high-speed signal terminal pairs and low-speed signal terminal pairs respectively, so that the radiated interference of the high-speed signals of the multiple high-speed signal terminal pairs and the low-speed signals of the low-speed signal terminal pairs is reduced to an acceptable range. In this way, the radiated interference between low-speed signals and high-speed signals can be effectively suppressed, as well as the radiated interference between the high-speed signals of multiple high-speed signal terminal pairs. This reduces the degree of attenuation and distortion of low-speed and high-speed signals of the USB board connector during transmission, thereby meeting the signal transmission requirements for low-speed and high-speed signals in the USB board connector specification.

[0098] The above embodiments are merely illustrative of the principles and effects of this application and are not intended to limit this application. Any person skilled in the art can modify and alter the above embodiments without departing from the spirit and scope of this application. Therefore, the scope of protection of this application should be as set forth in the claims.
