Description

Technical Field

[0001] This application relates to the field of connectors, and more specifically, to a side-standing double-shielded USB connector socket and connector. Background Technology

[0002] With the rapid development of electronic devices and the increasing demand for data transmission, USB (Universal Serial Bus) technology has become an indispensable interface standard in modern electronic devices. As a key component for data transmission, the performance of the USB connector directly affects the data transmission rate and signal integrity.

[0003] In existing technology, USB connectors typically consist of two parts: a male connector and a female connector. The female connector receives the male connector and establishes an electrical connection. Common USB female connectors use a single-layer metal shielding shell structure. This design primarily uses the metal shell to electromagnetically shield the internal signal lines. However, with the iterative upgrades of the USB protocol and the significant increase in data transfer rates (such as USB 3.0 and above), the single-layer shielding structure has gradually shown limitations in suppressing high-frequency signal interference.

[0004] Specifically, when the transmission rate reaches 5Gbps and above, the electromagnetic radiation generated by the signal line will significantly increase. Existing single-shielded shell structures, lacking multiple shielding mechanisms, cannot effectively block external electromagnetic interference and are also unable to suppress internal signal crosstalk. This electromagnetic compatibility issue leads to a decrease in signal quality and insufficient eye diagram opening, thus limiting the actual increase in transmission rate. Furthermore, in high-speed data transmission scenarios, the edge effect of a single-layer shielding structure can cause uneven shielding effectiveness, further affecting the stability of signal transmission. Utility Model Content

[0005] The purpose of this application is to provide a side-standing double-shielded USB connector socket and connector, which can improve the shielding function and enhance the stability of signal transmission.

One transmission pin passes through one soldering slot and is soldered to the wall of the soldering slot. The side of the first insulating shell is provided with a mounting hole. The PCB board is disposed in the mounting hole and fixedly connected to the first insulating shell. The second insulating shell covers the first insulating shell and has an opening that exposes the PCB board.

In this embodiment, the soldering slots can be set in two rows, with one row having five soldering slots and the other row having four soldering slots. Each row of soldering slots is arranged at intervals along the length of the PCB board 100.

[0027] The number of transmission pins 200 is consistent with the number of welding slots and corresponds one-to-one. One transmission pin 200 passes through one welding slot, and the transmission pin 200 is welded to the wall of the welding slot.

[0028] The first insulating shell 300 has mounting holes on its side, and the PCB board 100 is disposed in the mounting holes and fixedly connected to the first insulating shell 300.

[0029] Specifically, the first insulating shell 300 has a cuboid structure.
