Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector connectable to a docking connector.

Typically, Serial ATA (Serial Advanced Technology Attachment, an industry-standard tandem hardware driver interface) electrical connector with an L-shaped tongue that is slightly thinner than the standard interface. The root conductive terminals are arranged on the surface of the L-shaped tongue to form a standard Serial ATA interface as a whole, thereby achieving mating with the mating connector.

However, the seven conductive terminals on the surface of the L-shaped tongue only transmit the differential pair signal and do not transmit the power signal.

Therefore, it is necessary to provide an improved structure to overcome the above drawbacks.

The purpose of this creation is to provide an electrical connector that provides both signal transmission and power transmission functions.

In order to achieve the above object, the present invention is an electrical connector comprising an insulative housing and a plurality of first conductive terminals. The insulative housing has a mating frame opening through the front end surface, and an L-shaped tongue plate extends in the mating frame port, and the mating frame port has Two opposite inner end faces opposite the inner end surface facing the tongue plate and spaced apart from the two ends of the tongue plate, the first conductive terminal comprising a contact portion arranged on the tongue plate and a connecting leg extending from the insulating body, The electrical connector further includes a second conductive terminal disposed on the two inner end faces of the docking frame opening.

Compared with the prior art, the electrical connector of the present invention is provided with a second conductive terminal for transmitting a power signal, and provides a function of signal transmission and power transmission while satisfying the SATA specification connector.

The fourth figure is a cross-sectional view of the electrical connector shown in the first figure taken along line IV-IV.

As shown in the first figure, the present invention has an insulative housing 1 and a plurality of first conductive terminals 21 and second conductive terminals 22, and the insulative housing 1 is provided with a mating frame opening 101 extending through the front end surface. The frame opening 101 is extended with an L-shaped tongue plate 11, and the above elements will be described in detail below.

Referring to the second and third figures, the insulative housing 1 has a substantially hexahedral shape. The lower wall surface of the mating frame opening 101 of the insulative housing 1 is provided with an opening 102 for facilitating the opening of the insulative housing. The mating frame opening 101 of the insulative housing has two opposite inner end faces 12, and the inner end face 12 is provided with a terminal slot 121. The opposite inner end faces 12 of the mating frame opening 101 face the two ends of the tongue plate 11 and are spaced apart from the two ends of the tongue plate 11 for abutment of the docking connector. The tongue plate 11 is L-shaped and includes a long side 111 and a short side 112 perpendicular to the long side 111. The short side 112 is parallel to the inner end surface 12. The long side 111 of the tongue 11 is provided with a row of terminal slots 122, and the first conductive terminals 21 are received in the terminal slots 122.

The first conductive terminal 21 is inserted into the insulative housing 1 from the rear to the front and fixed in the terminal slot 122. The second conductive terminal 22 is inserted into the insulative housing 1 from the rear to the front and fixed in the terminal slot 121. The first and second conductive terminals 21/22 are of a flat type, the first conductive terminals 21 are horizontally placed in the terminal slots 122, and the second conductive terminals 22 are vertically placed in the terminal slots 121. The first conductive terminal 21 includes two pairs of differential pair signal terminals 211 and three ground terminals 212 that separate the two pairs of differential pair signal terminals 211. The second conductive terminal 22 transmits a power signal, and satisfies the function of the SATA specification connector to simultaneously provide signal transmission and power transmission. The second conductive terminal 22 has the same structure as the ground terminal 212, and the signal terminal 211 is slightly different.

The first and second conductive terminals 21 / 22 include a contact portion 23 , a holding portion 24 fixed to the rear wall of the insulating body 1 and a connecting leg 25 extending from the insulating body 1 . The holding portion 24 includes two protrusions 241 and two notches 242. The protrusions 241 and the notches 242 are spaced apart from each other, and can be more firmly mounted in the terminal slots 121/122 of the insulative housing 1. The contact portion of the signal terminal 211 and the connection portion 25 of the ground terminal 212 are coplanar with the contact portion 23, and the connection leg 25 of the differential pair signal terminal 211 is offset from the contact portion 23. As shown in the fourth figure, the connecting legs of the two pairs of differential pair signal sub-211 are bent away from each other by a certain distance, which can meet the transmission requirements of high-frequency signals. The terminal slot 121/122 is further provided with a notch 120 at the holding portion 24 of the conductive terminal to facilitate insertion of the conductive terminal into the terminal slot and to match the impedance when the high frequency signal is transmitted.

The creative electrical connector is provided with a second conductive terminal 22 for transmitting a power signal, which satisfies the function of the SATA specification connector for simultaneously providing signal transmission and power transmission.
