Contact insulators for use with differential pairs of contacts and method of termination

A contact insulator for use with high speed cable with differential pairs of contacts, the contact insulator comprising:

• a contact receiving portion having a first closed side, a second closed side and a third open side;
• a conductor receiving portion having a first closed side, an oppositely facing second open side;
• a transition portion positioned between the contact receiving portion and the conductor receiving portion;
• two contact receiving slots provided in the contact receiving portion, the contact receiving slots extending from a mating end of the contact insulator to the transition portion;
• two conductor receiving slots provided in the conductor receiving portion, the conductor receiving slots extending from a conductor receiving end of the contact insulator to the transition portion;
• the second open side and the conductor receiving slots of the conductor receiving portion opening in an opposite direction as the third open side and the contact receiving slots of the contact receiving portion;
• the transition portion having a contact receiving opening which extends through the contact insulator from the second open side of the conductor receiving portion to the open third side of the contact receiving portion, the contact receiving opening is dimensioned to allow the contacts to be inserted therethrough;
• access openings extending through either the first closed side or the second closed side and extending into the contact receiving slots, the access openings dimensioned to receive a removal tool therein to facilitate the removal of contacts positioned in the contact receiving slots.
