Background technology
Between the memory of general data center and office etc. or the wiring harness that is to use front end at cable to be connected with connector in the data communication of the transmitting range of several m that carry out between server and the memory to about the 10m carry out, for wiring harness is connected to printed circuit board, also use the connector that is connected with substrate.
Existing communication cable has the mode of using optical fiber and the mode of using copper cash.In the optical fiber mode, owing to be light signal, and the light signal of modulation is sent data by optical fiber with converting electrical signal, thus reduce with the decay of the metallic cable ratioing signal that makes electric signal streams come to communicate by letter, thus can grow the data communication of distance.In addition, owing to compare sewing of easy blocking light signal with the signal of telecommunication, so tie up the also advantage of non-interference of optical fiber in a large number even also have.But there is following problem in the optical fiber mode, owing to connector that connects and the machine that carries out the conversion of above-mentioned signal cost an arm and a leg, so in the in-plant data communication about below 10m, cost up.
On the other hand, in the mode of using copper cash, become the structure that covers the inner conductor that is made by metals such as copper with insulator, it is by making the signal of telecommunication flow through the mode that inner conductor carries out data communication.In this mode, because the decay of signal was big when long distance transmitted, so be mainly used in in-plant communication, and can have and in optical-fibre channel, be several Gbps, be the transfer rate more than the 10Gbps, but transmit at a high speed that electromagnetic interference problem is also just big more in infinite bandwidth, and the influence of the emitting of the signal of the connector that is connected with cable, external noise becomes problem.
As the plug that is used to address the above problem, for example disclosed as patent documentation 1, electric connector is arranged, it is the substrate that is used to connect the differential cable with a plurality of holding wires and drain line, this electric connector is characterised in that, comprising: substrate has a plurality of holding wire bonding conductors and drain line bonding conductor, described a plurality of holding wire bonding conductor is connected with described a plurality of holding wires respectively, and described drain line bonding conductor is used to connect described drain line; Cover is made of the conductor that is used for being connected with described drain line bonding conductor, and the local or whole connecting portion that covers described a plurality of holding wires and described a plurality of holding wire bonding conductors; By described drain line is connected with described cover, can be connected with described drain line bonding conductor.According to this connector, can suppress the electromagnetic interference between the adjacent holding wire.
But, in the connector of patent documentation 1, though improved the problem of the electromagnetic interference between the conductor, but owing to transmit the conductor part of the signal of telecommunication is complicated shape, so be difficult to keep equably characteristic impedance, and, the part that the signal that is transmitted changes at the state of transmission medium, here be the variation that causes reflection or electromagnetic transfer rate in the coupling part of cable and connector, thereby distortion takes place in the signal of telecommunication.As a result, the problem that exists communication speed to worsen.
