Cable

A cable comprising:

• a plurality of wire groups each including a pair of inner conductors and an outer coating layer enclosing the pair of inner conductors;
• a first insulating layer covering the plurality of wire groups;
• a first shielding layer covering the first insulating layer;
• a second shielding layer covering the first shielding layer;
• an outer insulating layer covering the second shielding layer;
• and
• an inner support member disposed inside the first insulating layer;
• wherein
• the inner support member includes a plurality of grooves with equal cross-sectional areas, one side of each wire group is disposed in a corresponding one of the plurality of grooves and in close contact with the inner support member, the other side of each wire group is in close contact with the first insulating layer to fix each wire group, and the inner support member is made of silicone;
• and
• the inner support member includes a middle portion disposed in a middle of the plurality of wire groups, at least two supporting portions in contact with the outer coating layers of the plurality of wire groups, and at least two concave surfaces formed between the supporting portions for limiting the plurality of wire groups.
