Socket connector

This creation is about a connector, especially a socket connector that reduces electromagnetic interference.

Universal Serial Bus (USB) is the current electronic peripheral product (such as desktop computer, mobile computer, mobile communication device or digital camera, etc.) because of its plug-and-play and high transmission speed. The most widely used transmission interface.

With the advancement of technology, the transmission efficiency of universal serial bus is also continuously improved (from USB1.1 to the current USB3.0 specification). The reason why the universal serial bus is widely promoted is one of the important reasons. Capacitive, that is to say, the USB3.0 interface can be compatible with the old USB2.0 and USB1.1 devices to greatly accelerate the popularity of USB3.0.

But relatively speaking, as the interface of the universal serial bus is constantly updated and evolved, it will inevitably add many signal terminals. For example, because the USB3.0 specification can be compatible with the old USB2.0 and USB1.1 devices, Therefore, in addition to the USB3.0 signal terminal itself, the USB3.0 specification must include a signal terminal that is downward compatible with USB2.0 and USB1.1, and is susceptible to electromagnetic interference between different signal terminals. And because the transmission rate of USB3.0 is greatly increased, the electromagnetic interference generated is also more serious.

In view of the above problems, the present invention provides a socket connector including an insulative housing, a two-terminal holder, a baffle plate and an outer casing. The insulating body includes opposite upper and lower sides. The two terminal blocks are respectively disposed on the upper side and the lower side of the insulative housing, and each of the terminal blocks includes a grounding piece, a plurality of first signal terminals and a plurality of second signal terminals arranged at intervals. The baffle plate is disposed between at least one of the first signal terminals and the adjacent second signal terminal, and the baffle plate is connected to the grounding piece of the two terminal block. The outer casing is disposed outside the insulating body.

Therefore, the present invention is disposed between the first signal terminal and the adjacent second signal terminal through the baffle barrier, so as to greatly reduce electromagnetic interference between different signals. For example, when the first signal terminal is the USB2.0 signal transmission terminal and the second signal terminal is the USB3.0 signal transmission terminal, the blocking plate is disposed on the first signal terminal and the second signal terminal, thereby avoiding the USB3.0. The electromagnetic field generated by the signal transmission terminal during high-speed transmission interferes with the signal transmission terminal of USB2.0. In addition, the baffle plate is further connected to the grounding piece of the two terminal block, so that the socket connector has a better grounding effect.

In an embodiment, the insulative housing is further provided with a main grounding strip, and the main grounding strip is provided with a through hole, so that the blocking baffle can be inserted into the through hole to connect the grounding piece of the two terminal block.

In one embodiment, the two sides of the baffle plate may be respectively provided with flanges, each of which abuts against the grounding piece of the two terminal block, and the baffle plate further has a lateral groove between the flanges, thereby The two sides of the lateral groove form a resilient arm to prevent contact between the baffle plate and the ground plate due to manufacturing tolerances.

In an embodiment, the baffle plate and the main grounding piece may also be integrally formed, for example, by integral stamping, and the two sides of the baffle plate respectively abut against the grounding piece contacting the two terminal block, thereby increasing the structural strength of the baffle plate. .

In an embodiment, each of the first signal terminals may include a first electrical contact segment and a first intermediate segment connected to the first electrical contact segment, and each of the second signal terminals includes a second electrical contact segment And a second intermediate section connected to the second electrical contact section, and a distance between the first intermediate section of at least one of the first signal terminals and the adjacent second signal terminal is greater than the first electrical contact section The distance from the adjacent second signal terminal. Thereby, by increasing the separation distance between the first signal terminal and the second signal terminal, the effect of further reducing electromagnetic interference can be achieved.
