Abstract
Description
Technical Field
[0001] This application relates to signal transmission technology, and more specifically, to a USB cable 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 cable 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.

The bottom low-speed signal terminal pair is located between the left-bottom high-speed signal terminal pair and the right-bottom high-speed signal terminal pair. A middle horizontal spacer is located between the top terminal group and the bottom terminal group. A left-top high-speed signal shielding structure overlaps the middle horizontal spacer. A high-speed signal shielding chamber is formed at the top left, with at least one portion of the high-speed signal terminal pair at the top left located within the chamber. This shields the high-speed signal shielding chamber from radiation originating from the top low-speed signal, the top right high-speed signal, the bottom left high-speed signal, the bottom low-speed signal, or the bottom right high-speed signal, reducing the radiated interference to the top left high-speed signal from these signals to an acceptable level. A top low-speed signal shielding structure is also included. The high-speed signal shielding structure overlaps with the intermediate transverse spacer to form a top low-speed signal shielding chamber. At least one part of the top low-speed signal terminal pair is located in the top low-speed signal shielding chamber, so that the top low-speed signal shielding chamber shields the radiation from the left top high-speed signal, the right top high-speed signal, the left bottom high-speed signal, the bottom low-speed signal, or the right bottom high-speed signal, so that the radiation interference of the left top high-speed signal, the right top high-speed signal, the left bottom high-speed signal, the bottom low-speed signal, or the right bottom high-speed signal to the top low-speed signal is reduced to an acceptable range.A high-speed signal shielding structure is provided at the top right, which overlaps with the intermediate transverse spacer to form a high-speed signal shielding chamber at the top right.

This shielding chamber protects the high-speed signal from radiation originating from the high-speed signal at the top left, the low-speed signal at the top, the high-speed signal at the bottom left, the low-speed signal at the bottom left, or the high-speed signal at the bottom right, thereby reducing the radiated interference from these signals to the high-speed signal at the top right to an acceptable level. 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. This reduces the radiated interference from the high-speed signal at 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 to an acceptable level. A bottom low-speed signal shielding structure is provided, which overlaps the intermediate transverse spacer to form a bottom low-speed signal shielding chamber. At least one portion of the bottom low-speed signal terminal pair is located within the bottom low-speed signal shielding chamber, so that the bottom low-speed signal shielding chamber shields radiation from the left top high-speed signal, the top low-speed signal, the right top high-speed signal, the left bottom high-speed signal, or the right bottom high-speed signal, thereby reducing the radiated interference of the left top high-speed signal, the top low-speed signal, the right top high-speed signal, the left bottom high-speed signal, or the right bottom high-speed signal to the bottom low-speed signal to an acceptable range; and A high-speed signal shielding structure is provided at the bottom right, which overlaps with the intermediate transverse spacer to form a high-speed signal shielding chamber at the bottom right.

This reduces the radiated interference from the top left, top right, top low-speed, bottom left, or bottom high-speed signals to the high-speed signal at the bottom right to an acceptable level.

[0071] The following describes the technical concept of this application through several embodiments. In the following embodiments, the same or similar components are identified by the same symbols, and the description of the same or similar technical features will be omitted:
[0072] First Embodiment
[0073] In this application, as Figures 11 to 12 As shown, the USB cable connector 1 is used in conjunction with the circuit board 2 to transmit high-speed and low-speed signals. Specifically, as... Figures 1 to 10As shown, the components of the USB cable connector 1 may optionally include a top terminal group 11, a bottom terminal group 12, a middle lateral spacer 13, a left top high-speed signal shielding structure 141, a top low-speed signal shielding structure 142, a right top high-speed signal shielding structure 143, a left bottom high-speed signal shielding structure 144, a bottom low-speed signal shielding structure 145, and a right bottom high-speed signal shielding structure 146. However, the components of the USB cable connector 1 may be omitted or other components may be added depending on the actual use, and are not limited to the above.
[0074] like Figure 2 As shown, the top terminal group 11 includes a left top high-speed signal terminal pair 111 for transmitting a left top high-speed signal, a top low-speed signal terminal pair 112 for transmitting a top low-speed signal, and a right top high-speed signal terminal pair 113 for transmitting a right top high-speed signal, wherein the top low-speed signal terminal pair 112 is located between the left top high-speed signal terminal pair 111 and the right top high-speed signal terminal pair 113.
[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 3 As 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 Figure 13 As shown, the left top high-speed signal shielding structure 141 is formed by at least one top shielding shell B1. The left top high-speed signal shielding structure 141 overlaps with 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 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.
[0078] In addition, such as Figure 4As shown, the first top shielding housing B1 is composed of a top shielding cover 161. The top shielding cover 161 is formed by bending to create a left top wing 1411 located between the left top high-speed signal terminal pair 111 and the top low-speed signal terminal pair 112. The left top wing 1411 provides separation 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 level. Figure 4 As shown, the left top wing 1411 may have multiple separately arranged left top sub-wings 14111 to separate the left top high-speed signal terminal pair 111 and the top low-speed signal terminal pair 112 at multiple locations, which can also reduce the radiated interference between the left top high-speed signal and the top low-speed signal to an acceptable range.
[0079] like Figure 17 As shown, the first part of the top low-speed signal shielding structure 142 is formed by at least the first top shielding shell B1. Figure 15 As shown, the second part of the top low-speed signal shielding structure 142 is formed by at least a first top shielding shell B1 and a second top shielding shell B3. The top low-speed signal shielding structure 142 overlaps with the intermediate transverse spacer 13 to form a top low-speed signal shielding chamber E2, and 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 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.
[0080] like Figure 13 As shown, the right top high-speed signal shielding structure 143 is formed by at least one top shielding shell B1. The right top high-speed signal shielding structure 143 overlaps with the intermediate transverse spacer 13 to form a right top high-speed signal shielding chamber E3. 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 4As shown, the first top shielding housing B1 is composed of a top shielding cover 161. The top shielding cover 161 is bent to form a right top wing 1431 located between the right top high-speed signal terminal pair 113 and the top low-speed signal terminal pair 112. The right top wing 1431 separates 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. Figure 4 As shown, the right top wing 1431 may have multiple separately arranged right top sub-wings 14311 to provide shielding between the right top high-speed signal terminal pair 113 and the top low-speed signal terminal pair 112 at multiple locations, 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 15 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. At least one of these left top sub-wings 14111 extends between the left top high-speed signal pin pair 1111 and the top low-speed signal pin pair 1121, and connects 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. At least one of these right top sub-wings 14311 extends between the right top high-speed signal pin pair 1131 and the top low-speed signal pin pair 1121, and connects 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 left bottom high-speed signal shielding structure 144 is formed by at least one first bottom shielding shell B2. The left bottom high-speed signal shielding structure 144 overlaps with 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] In addition, such as Figure 4 As shown, the first bottom shielding housing B2 is composed of a bottom shielding cover 162. The bottom shielding cover 162 forms a left bottom wing 1441 located between the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122 by bending. The left bottom wing 1441 separates the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122, thereby reducing the radiated interference between the left bottom high-speed signal and the bottom low-speed signal to an acceptable range. Figure 4 As shown, the left bottom wing 1441 may have multiple separately arranged left bottom sub-wings 14411 to separate the left bottom high-speed signal terminal pair 121 and the bottom low-speed signal terminal pair 122 at multiple locations. In this way, the radiation interference between the left bottom high-speed signal and the bottom low-speed signal can be reduced to an acceptable range.
[0085] like Figure 17 As shown, the first part of the bottom low-speed signal shielding structure 145 is formed by at least the first bottom shielding shell B2. Figure 13 As shown, the second part of the bottom low-speed signal shielding structure 145 is formed by at least a first bottom shielding shell B2 and a second bottom shielding shell B4. The bottom low-speed signal shielding structure 145 overlaps with the intermediate transverse spacer 13 to form a bottom low-speed signal shielding chamber E5. At least one portion of the bottom low-speed signal terminal pair 122 is located inside 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 radiation 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.
[0086] like Figure 13 As shown, the right bottom high-speed signal shielding structure 146 is formed by at least the first bottom shielding shell B2. The right bottom high-speed signal shielding structure 146 overlaps with the intermediate transverse spacer 13 to form the right bottom high-speed signal shielding chamber E6. At least one portion of the right bottom high-speed signal terminal pair 123 is located inside 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 the electromagnetic field and other radiation 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.
[0087] In addition, such as Figure 4As shown, the first bottom shielding housing B2 is composed of a bottom shielding cover 162. The bottom shielding cover 162 forms a right bottom wing 1461 located between the right bottom high-speed signal terminal pair 123 and the bottom low-speed signal terminal pair 122 by bending. The right bottom wing 1461 separates the right bottom high-speed signal terminal pair 123 and the bottom low-speed signal terminal pair 122, reducing the radiated interference between the right bottom high-speed signal and the bottom low-speed signal to an acceptable range. Figure 4 As shown, the right bottom wing 1461 may have multiple separately arranged right bottom sub-wings 14611 to separate the right bottom high-speed signal terminal pair 123 and the bottom low-speed signal terminal pair 122 at multiple locations. In this way, the radiated interference between the right bottom high-speed signal and the bottom low-speed signal can be reduced to an acceptable range.

At least one of these left bottom sub-wings 14411 extends between the left bottom high-speed signal pin pair 1211 and the bottom low-speed signal pin pair 1221, and connects 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. At least one of these right bottom sub-wings 14611 extends between the right bottom high-speed signal pin pair 1231 and the bottom low-speed signal pin pair 1221, and connects 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.

Next, as... Figures 4 to 8As 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.

[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 20 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 21 to 22As 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 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 connector during transmission, thereby meeting the signal transmission requirements for low-speed and high-speed signals in the USB connector specification.
