The United States Patent (USP) the 6th that on June 6th, 2000 was announced, 071, disclosed a kind of adapter No. 150, comprise a male end and a female end, male end and female end fits together between the public connector of the female connectors that is connected the computer back shroud and Hard Disk Drive, interconnected to set up the signal transmission between Hard Disk Drive and the back shroud by this male end and female end.Specifically, female end is provided with the female contact-making surface in order to the public connector that connects Hard Disk Drive, male end is provided with the public contact-making surface with respect to female contact-making surface in order to the female connectors that connects the computer back shroud, and plurality of terminals is extended to electrically connect female end and male end to public contact-making surface from female contact-making surface.This structure generally makes female contact-making surface or public contact-making surface that the public connector of Hard Disk Drive or the same voltage of female connectors of back shroud can be provided.
On July 19th, 2005, the United States Patent (USP) of bulletin disclosed a kind of electric connector the 6th, 918, No. 774, comprised insulating body, and insulating body comprises the forward and backward body that is provided with some conduits and connects preceding body and the pars intermedia of back body.Some lengthwise circuit boards are immobilizated in the insulating body side by side, and extend along the second direction perpendicular to first direction, and circuit board comprises in the conduit that is contained in forward and backward body respectively in order to connect the forward and backward butt end of butt connector.
On December 16th, 2003, the United States Patent (USP) of bulletin disclosed a kind of adapter the 6th, 663, No. 434, comprised back-to-back female end that fits together and male end.Female end comprises first body with two slits and some the first terminals, and some first grooves are arranged in first body and with slit and communicate, and the first terminal is immobilizated in first groove.Male end comprises second body with a pair of hyoplastron and some second terminals, and hyoplastron is provided with in order to accommodate some location notchs of second terminal.Each the first terminal and corresponding second terminal align and arrange and cooperatively interact to form transmission path.Two make-up gripping arms are arranged at two opposite ends of female end and male end, so that both are tightened together.
In the prior art, as the electric equipment of Hard Disk Drive and so on have identical voltage usually with the back shroud of electric equipment electrical interconnects, promptly both operate under the identical substantially operational environment.Yet more and more faster when message transmission rate, their operational environment has to change to satisfy the demand thereupon.
The existing issue that the user faces is require a predetermined voltage when contact-making surface of male end and female end assembles, and the electric connector acquisition to be another predetermined voltage.In other words, traditional structure does not have ability to provide different voltage at dissimilar electric connectors.
In addition, when the message transmission rate demand was more and more higher, difference signal terminal was to being used, and in case used difference signal terminal right, ground connection that difference signal terminal is right or shielding problem become one new problem to be solved.When the signal terminal of different differential pairs and another terminal match, signal terminal shows as cross-communication, cross-communication has increased circuit board, connector and intrasystem interference, noise and shake, increases the influence that distance between the signal terminal of each differential pair can weaken interference, noise and shake.Increase differential terminal between distance can need bigger connector.Yet electric now, electronic application needs a lot of differential terminal to being installed in the limited little space.A lot of systems need as far as possible little connector effectively to utilize the inner space.In prior art described above, all do not consider the use that differential terminal is right.And, earthing device and the circuit substrate that adapter is installed between first interface and second interface are not provided in the prior art yet.
