FIELD: electricity.
SUBSTANCE: RCA jack includes a great number of external contact pins (51) and inner contact pins (51'). External contact pins (51) form the shape of external surface (41) of a fixed connector (4) so that contact surface (511) of each of these pins touches external surface (41) of this fixed connector (4). Inner contact pins (51) form the shape of inner surface (42) of a fixed connector (4) so that contact surface (511) of each of these pins touches inner surface (42) of this fixed connector (4). Each contact pin (51, 51') has the first convex contact area (512, 512') to contact surfaces (41, 42) of the fixed connector (4) and the second convex contact area (513) to contact a bushing (6). Besides each convex contact area (512, 512') has a contact slot (515) at its surface. The first convex contact areas (512) of external contact pins (51) are located in a different cross-section apart from the first convex contact areas (512') of inner contact pins (51'). The fixed connector contains a number of holes (44) for ventilation purpose.
EFFECT: improving heat removal and reliability, structural strength and electrical conductivity.
