Abstract

An electrical shielded data connector includes an inner terminal support housing (46) carrying a plurality of electrical terminals (30) and includes shield members (130) surrounding the terminal support housing (46). This shielded sub-assembly is fitted into an outer housing and a rear support plate and cable support member can be assembled around a cable after the connector has been attached to the cable. The cable support member can be positioned in one of two orientations to provide for either a straight through or an angled cable exit. A cross talk shield (200) is positioned in a stuffer cap and is situated between adjacent terminals (30) when in the final position. Another cross talk shield (220) is positioned in a slot intermediate the terminals (30) at the lower side thereof. <IMAGE>

You. These electrical connectors are of a type like computer terminals.
Used for closed loop data networks where various devices are interconnected
Is done. These electrical connectors are especially useful in office environments.
Many micros in a microcomputer network
When interconnecting computers or minicomputers
It is suitable. This type of electrical connector has a standard interface
It has face dimensions and shape. These electrical connectors
Signal and noise adversely affect signals in the network
Need to be shielded from giving. Change
These electrical connectors often have conductors that
And can be connected to other similar electrical connectors.
It is also required to be able to shunt. This short circuit
What is possible is that one of the plugs is not connected to an external device.
Needed to avoid network disruption when
You. Structure and components of this type of LAN connector
Is based on the connector structure of the aforementioned U.S. Patent No. 4,501,459.
It is shown. These electrical connectors are multi-core coaxial cables
For crimping for electrical connection to individual conductors forming
Numerous spring-like cylindrical metal terminals with a barrel structure
Including. The terminals are located on the housing, and

Provides a shield around the connector
Avoids interference with signals into the cubicle. Such a connection
Kuta is widely used. However, conventional connectors
A pair of twisted pair conductors are untwisted with each other
Signal crossing at the end of each conductor when (detwisted)
Talk (crosstalk) was not considered. Therefore, the conventional
Electrical connectors prevent signal interference from outside the connector.
Suppress crosstalk between signal conductors inside connectors
I couldn't do that. Conventional electrical connectorIsEngagement contact and phase
With four electrical terminals having interconnected wire connections
Divided into four parts. Two knives with normal twist
The twisted pair of conductors untwist at the end by a short distance
WireConnectionInterconnected to the terminals. Between each pair
Crosstalk is caused by twisting the pair
It is widely known that this is reduced by the cost. Follow
And untwisting for a short distance is due to torsionOfferSa
This reduces crosstalk compensation. Torsion
Solving is not a problem for low frequency signals,,high frequency
Signal transmission causes signal interference between pairs. [0005] An object of the present invention is to provide a signal conductor.
At the same time as preventing crosstalk between adjacent pairs
Low cost system with excellent electromagnetic and high frequency shielding functions
To provide a cold-type electrical connector assembly. [0006] SUMMARY OF THE INVENTION The present invention provides a wire conductor receiver.
