Description

The wire and cable connector device

The utility model relates to a kind of wire and cable connector device, especially can prevent cable transmission generation cross-talk, and can integrate the ground connection signal in the transmission signal simultaneously, to realize the wire and cable connector device of good high-speed transfer effect.

At present, for realizing the transmission of signal or electric power with perimeter systems, computer cpu and motherboard can use winding displacement or electric wire to cooperate suitable connector to finish the electric connection of motherboard and perimeter systems usually.Wherein winding displacement is to coat several leads and forming side by side by insulated part, and this type of winding displacement is unfavorable for that each lead is done telecommunication one by one to be connected because number of lead wires is more, and spacing is less.So these winding displacements adopt the in addition winding of punch through style connector more so that assembling rapidly, and be able to be located at motherboard or perimeter systems on corresponding connector dock conducting each other.Relevant patent sees also United States Patent (USP) the 4th, 190, and 952,4,508,401,4,596,428 and 4,749, No. 371 etc.But the speed of handling data with computer cpu and each perimeter systems is more and more fast; strictness is also more seen in requirement to the cable quality of being responsible for transmission signal; especially under high-speed transfer; there is the phenomenon that interferes with each other in regular meeting between the adjacent wires of each cable; be so-called cross-talk (Cross talking); thereby will have a strong impact on the stable transfer of cable, and cause transmission quality to be affected.

Main purpose of the present utility model is to provide a kind of wire and cable connector device, and it can provide preferable cable lead arrangement and opposing connector structure avoiding the phenomenon of cable generation cross-talk, and guarantees the quality of telecommunication transmission.An of the present utility model purpose is that this wire and cable connector device can constitute complete electrical shield ranges by means of the earthing device that suitably is provided with, and makes the transfer wire of cable can obtain good covering, and can not be subjected to the interference of other leads or extraneous noise.

Another purpose of the present utility model is that the wire and cable connector device can integrate the ground connection signal of cable transmission simultaneously, makes it integrate earthing device and reaches best electrical shield effect.

The connector body that is characterised in that of the present utility model is provided with terminal installing hole in a row of going into for terminal group and the mounting groove of going into for the earthing device group, and it can cooperate lid that cable clamp is held between the arc-shaped recess of the insulation shell junction of connector body and lid inboard.This cable has several transfer wires and is located at earth lead between two transfer wires, and can distinguish clamping and conducting on each terminal and earthing device, to constitute complete electrical shield effect, also can borrow earthing device to integrate ground connection signal in the transmission signal synchronously in addition, and constitute splendid ground connection and electrical shield effect.

Adopt such scheme, can prevent cable transmission generation cross-talk, and can integrate the ground connection signal in the transmission signal simultaneously, to realize the wire and cable connector device of good high-speed transfer effect.
