Cable connector and cable assembly, and method of manufacturing cable assembly

A cable assembly including:

• a cable for differential signal transmission;
• and a cable connector which is electrically connected with the cable for differential signal transmission,
• the cable for differential signal transmission comprising:
• a pair of signal line conductors;
• an insulator provided in peripheries of the respective signal line conductors;
• and
• an outer conductor provided in periphery of the insulator, and
• the cable connector comprising:
• a connector board made of an insulating material;
• a first ground contact and a second ground contact which are provided in the connector board and are electrically connected with the outer conductor;
• a pair of signal line contacts which are provided between the respective ground contacts in the connector board through a space and are electrically connected with the respective signal line conductors;
• and
• a first arm portion and a second arm portion which are provided integrally with end portions of the respective ground contacts protruded from a side wall portion of the connector board, which mutually extend toward the respective signal line contacts, and which hold the outer conductor under a state that the respective signal line conductors are arranged in the respective signal line contacts.
