Abstract
This invention relates to an improved jack for data transmission, and in particular provides the jack having improved cross-torque characteristics. A jack is provided comprising a body having m unted thereon a multiplicity of metal strips. The strips include a first group of metal strips each of which includes a contact portion (7) for contacting a conductor of a mating plug and a connection portion for connection to a printed circuit board on which the jack, in use, is mounted. The strips also include a second group of metal strips each of which extends parallel to at least one metal strip of the first group over a part of the length of the metal strip of the first group and which is electrically connected to a different metal strip of the first group.
Claims7
A jack comprising a body having mounted thereon a multiplicity of metal strips, the metal strips including:
- a first group of metal strips each of which includes a contact portion for contacting a conductor of a mating plug and a connection portion for connection to a printed circuit board on which the jack, in use, is mounted;
- a second group of metal strips each of which extends parallel and adjacent to at least one metal strip of the first group over a part of the length of the metal strip of the first group, each of the metal strips of the second group including a connection portion for connection to a printed circuit board on which the jack is, in use, mounted, an encapsulation encapsulating portions of all the metal strips such that the contact portions extend from a first side of the encapsulation and the connection portions extend from a second side of the encapsulation whereby the connection portions of the first group of metal strips may be connected to tracks of a printed circuit board to effect an electrical connection between each contact portion and a track on this printed circuit board;
- and means electrically connecting each metal strip of the second group and a metal strip of the first group which is different from the metal strip of the first group to which the metal strip of the second group lies adjacent.
A jack as claimed in any preceding claim, wherein the strips are formed by two superimposed layers of a pre-formed common blank, one of the layers of blank being inverted relative to the other layer.
A jack as claimed in any preceding claim, wherein at least some of the trips include pad portions which co-operate with the pad portions of others of the trips to enhance impedance matching characteristics of the jack.
