Description

Wire and cable connector

The utility model is a kind of wire and cable connector, refer in particular to a kind of cable transmission generation cross-talk that prevents, and can put the ground signalling in the transmission signals simultaneously in order, realizing stable high-speed transfer effect, and have the wire and cable connector device that the location cable reaches accurate winding function.

Computer cpu and motherboard be for the peripheral system connection signal or transmit electric power, can use winding displacement or electric wire to cooperate suitable connector to finish being connected of motherboard and peripheral system usually.In general winding displacement coats several leads and forming side by side by insulated part, this class winding displacement is because number of lead wires is more, spacing is less, be unfavorable for each lead is connected one by one, so, this type of winding displacement adopts the in addition winding of punch through style connector more, so that assembling rapidly, and can utilize this type of connector to dock conducting each other with the corresponding connector that is located at motherboard or peripheral system.As United States Patent (USP) the 4th, 190,952,4,508,401,4,596,428 and 4,749, No. 371 etc.; the speed of handling data with computer cpu and each peripheral system is more and more faster; more and more stricter to the cable transmission quality of being responsible for transmission signal; especially under the situation of 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), will have a strong impact on the transmission speed of cable like this, so that the high-speed transfer effect that can't play stably.In addition; usually be not provided with suitable positioner on the existing wire and cable connector; in advance cable is fixed for terminal puncture end aim at correct lead location assassinate again into; so regular meeting has to puncture holds improper the wear out insulated part of cable and the undesired situation generation that electrically connects with other leads formation.

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 the stable transmission of telecommunication fast is provided.

Another purpose of the present utility model is that this wire and cable connector device can utilize the earthing device of suitable setting to constitute complete electrical shield ranges, makes the transfer wire of cable can obtain good shielding, 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 put the ground signalling by cable transmission simultaneously in order, makes its arrangement earthing device reach shield effectiveness preferably.

A purpose more of the present utility model is suitably to locate cable, make terminal puncture end can be on the tram pierce cable, to avoid stinging the improper electric connection of wrong position.

The connector body that is characterised in that of the present utility model is provided with the terminal containing hole in a row of going into for terminal group, which is provided with a location device and can cooperate suitable location of lid and guiding cable to correct piercing orientation, and lid is provided with the group-connecting groove that can install the earthing device that extends towards positioner.

Compare prior art, the utlity model has following advantage:

1. avoid cross-talk;

2. better shield effect;

3. suitably locate cable.
