Jack for data transmission

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 a length of the metal strip of the first group, each of the metal strips of the second group having a first end forming a connection portion for connection to a printed circuit board on which the jack is, in use, mounted, and a second end which is spaced apart from said metal strips of said first group;
• an encapsulation encapsulating portions of all the metal strips such that the contact portions extend from a first side of the encapsulation whereby the connection portions of the first group of metal strips may be connected to tracks of the printed circuit board to effect an electrical connection between each contact portion and a track on the 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, such that each said metal strip of the second group forms a conducting spur connected only at one end to said metal strip of the first group.
