Electronic connector

This creation relates to an electronic connector, in particular to an electronic connector that transmits a high frequency signal.

Due to the vigorous development of information technology, in order to provide different transmission needs, and develop a variety of different transmission specifications, from the early SCSI (S mall C omputer S ystem I nterface) to the current SAS (Serial Attached SCSI, Serial SCSI), for The high-speed information access demand tandem technology solves the bottleneck of the traditional parallel technology, provides faster signal transmission and SAS can support and be compatible with SATA (Serial Advanced Technology Attachment) equipment, and has wide application advantages.

Under the demand of high-speed information transmission and the reduction of connector size, the arrangement between the complex terminals tends to be tight, and the frequency of signal transmission tends to be transmitted at a high frequency. Therefore, the connector is prone to signal interference when transmitting data due to the two signals. Because the distance between the terminals is too close, the signal terminals are capacitively and inductively coupled to each other during the high-frequency signal transmission, and there is a problem of cross talk interference and noise. This in turn affects the speed and accuracy of signal transmission.

In order to overcome the problem of crosstalk interference, in the prior art, a grounding terminal is disposed between the two high frequency signal terminals for blocking interference between the two signal terminals. The ground terminal can ground the capacitance and the inductance noise generated by the coupling of the signal terminals to reduce the interference of the signal. However, there is still room for improvement in the technical means for solving the crosstalk interference.

An electrical connector is disclosed in the US Patent Application Publication No. 2013/0149882. As shown in FIG. 11, the electrical connector has an insulative body A and a plurality of insulating bodies A. Conductive terminal B and a grounding strip C. The insulative housing A includes a base portion A1 and a tongue plate A2 extending from the base portion A1. The conductive terminals B have a plurality of grounding terminals B1 and a plurality of signal terminals (not shown), and the grounding terminals B1 respectively comprise a contact. a portion B11, a soldering portion B13, and a holding portion B12 connecting the contact portion B11 and the soldering portion B13. The contact portion B11 is arranged on a plane of the tongue plate A2. The holding portion B12 is disposed in the base portion A1. B13 extends out of the base A1 and is electrically connected to a circuit board (not shown). The arrangement of the conductive terminals B includes a signal terminal (not shown) between at least two ground terminals B1. The grounding plate C has a plurality of elastic arms C1 (Finger) and a beam portion C2. The elastic arms C1 are extended and electrically connected by the beam portion C2, wherein the elastic arms C1 contact the holding portions of the grounding terminals B1. B12 is disposed in the insulating body A.

In the above-mentioned technology, the grounding terminals B1 are electrically connected to each other by the elastic arms C1 of the grounding strip C, thereby generating impurities generated by the high-frequency transmission signals of the signal terminals (not shown). Grounding can reduce the crosstalk problem of the electrical connector.

However, in the prior art, the grounding terminals B1 and the grounding strip C are connected by using one of the corresponding elastic arms C1. However, the holding portion B12 of the grounding terminals B1 and the elastic arms C1 are only small in area. Contact, so the grounding terminal B1 transmits interference noise ground to the grounding piece C, because the contact area is small, and the transmission rate of the noise grounding is slow, resulting in high frequency signal interference of the electrical connector. Problem; and the elastic arm C1 and the ground terminal B1 are assembled The yield of the alignment and the contact condition of the elastic arm C1 contacting the ground terminals B1 are one of the factors that affect the noise grounding.

Since the prior art cannot provide a better crosstalk improvement method to meet the actual needs of the industry, it is necessary to provide an improved technical solution to overcome the dilemma.

The purpose of the present invention is to provide an electronic connector capable of transmitting a high frequency signal, and the connector has a grounding member for effectively reducing crosstalk interference when the plurality of signal terminals transmit high frequency signals.

The purpose of the present invention is that the grounding member has a pair of restraining portions and an extending portion, and the extending portion and the restraining portions can be used to fix and increase the area of contact with the plurality of grounding terminals, thereby effectively grounding the interference noise quickly to improve The transmission yield and speed of the electronic connector.

To achieve the above object, the present invention provides an electronic connector having an insulator, a plurality of conductive terminals, and a grounding member. The insulator has an insulative body and a tongue portion extending from a side of the insulative housing; the conductive terminals are staggered by a plurality of grounding terminals and a plurality of signal terminals, and the grounding terminals and the signal terminals respectively have a a contact portion, a tail end portion, and a main body portion connecting the contact portion and the tail end portion. The grounding member has a conductive body and a plurality of extending portions, and the extending portions extend from the conductive body, and each of the extending portions has a restraining portion on at least one side thereof, and the main body portion of each of the grounding terminals is at least partially The extension portion is stacked and is in contact with the restraining portion of the side, and the grounding member and the main body portions of the grounding terminals are fixed in the insulative housing, and the end portions respectively extend out of the insulative housing, the contact portions Do not be placed on the surface of the tongue.
