High-speed electrical connector assembly with shielding system

This creation is related to an electrical connector, especially a high-speed electrical connector with a shielding system for connecting electrical equipment to the back cover.

US Patent No. 6,071,150 issued on June 6, 2000 discloses an adapter, including a male end and a female end. The male end and the female end are assembled together to connect to the female connector of the computer back cover and the hard disk. Between the male connectors of the machine, the signal transmission between the hard disk drive and the rear cover is established through the interconnection of the male end and the female end. Specifically, the female end is provided with a female contact surface for mating with the male connector of the hard disk drive, and the male end is provided with a male contact surface relative to the female contact surface for mating with the female connector of the computer rear cover. The terminal extends from the female contact surface to the male contact surface to electrically connect the female end and the male end. This structure generally enables the female contact surface or the male contact surface to provide the same voltage for the male connector of the hard disk drive or the female connector of the rear cover.

US Patent No. 6,918,774, published on July 19, 2005, discloses an electrical connector including an insulating body. The insulating body includes a front body and a rear body provided with a plurality of channels, and a middle part connecting the front body and the rear body. A plurality of longitudinal circuit boards are held side by side in the insulating body and extend along a second direction perpendicular to the first direction. The circuit boards include the front and rear butting terminals respectively received in the slots of the front and rear bodies for mating the butting connectors .

US Patent No. 6,663,434 issued on December 16, 2003 discloses an adapter including a female end and a male end assembled back to back. The female end includes a first body having two slots and a plurality of first terminals. The first through slots are arranged in the first body and communicate with the slots, and the first terminals are held in the first through slots. The male end includes a second body with a pair of tongue plates and a plurality of second terminals. The tongue plates are provided with a plurality of positioning grooves for receiving the second terminals. Each first terminal and the corresponding second terminal are aligned and matched with each other to form a transmission path. Two pairs of buckling arms are arranged at two opposite ends of the female end and the male end to fasten the two together.

In the prior art, electrical equipment such as hard disk drives and the cover plate after being electrically interconnected with the electrical equipment usually have the same voltage, that is, the two operate in substantially the same working environment. However, as the data transmission rate becomes faster and faster, their working environment has to be changed accordingly to meet the needs.

The existing problem faced by users is that the contact surface of the male end and the female end requires a predetermined voltage when assembling, and the electrical connector obtains another predetermined voltage. In other words, the traditional structure is unable to provide different voltages for different types of electrical connectors.

In addition, when the data transmission rate requirements are getting higher and higher, the differential signal terminal pair is used, and once the differential signal terminal pair is used, the grounding or shielding problem of the differential signal terminal pair becomes a new problem to be solved. When the signal terminals of different differential pairs are paired with another terminal, the signal terminals appear as cross-communication. Cross-communication increases the interference, noise and jitter in the circuit board, connector and system, and increases the difference between each differential pair. The distance between the signal terminals can reduce the influence of interference, noise and jitter. Increasing the distance between the differential terminal pairs will require larger connectors. However, today's electrical and electronic applications require many differential terminal pairs to be installed in a limited space, and many systems require connectors as small as possible to effectively use the internal space. In the prior art described above, the use of differential terminal pairs is not considered. Moreover, the prior art does not provide a grounding device between the first mating surface and the second mating surface and a circuit substrate with an adapter mounted thereon.

A high-speed electrical connector assembly of this invention includes a female connector and a male connector assembled together and electrically connected to a circuit board. The female connector includes a first mating interface that is mated and installed on the mating surface of the mating connector of the hard disk drive. On the other hand, the male connector includes a second mating surface opposite to the first mating surface and used for mating with the connector installed on the back cover. The connector assembly includes a mounting surface that is perpendicular to the first and second mating surfaces and is used for mating circuit boards. The circuit board provides a predetermined voltage to the female connector and/or the male connector, so that the flexible connection of the connector combination with different types of hard disk drives and the rear cover can be realized.

In this creation, on the one hand, the female connector includes a first insulating body, and the first insulating body includes a first mating surface and a first mating surface opposite to the first mating surface.

The ground terminal includes a first terminal contact part close to the first mating surface, and a first terminal contact part extending from the first terminal contact part and perpendicular to the first terminal contact part to be electrically connected to the tail part of the circuit board.

On the other hand, the male connector includes a second insulating body having a second mating surface and a second mating surface opposite to the second mating surface. The plurality of channels extend from the mating surface to the joint surface to accommodate the second contact portions of the two rows of terminals extending from the female connector and the plurality of terminals extending from the second mating surface to the mounting surface. Each terminal of the male connector has a right-angle structure, and has a second terminal contact portion close to the second mating surface, and extends perpendicular to the first terminal contact portion to be electrically connected to the tail portion of the circuit board.

In another aspect, the first joint surface of the female connector and the second joint surface of the male connector include mutual interference elements extending thereon for fastening the female connector and the male connector.

The shielding integrated piece includes a frame, a plurality of bases connected to the metal cover and substantially covering the middle of the differential signal terminal pair, and a plurality of self-frames The extended elastic arm is used to electrically interconnect with the ground terminal.

Since the circuit board provides two predetermined voltages to the female connector and/or the male connector, the mating surface or the mating surface can be mated with electrical devices that require different predetermined voltages. Therefore, the electrical connector combination can flexibly connect devices that require different predetermined voltages.
