Abstract
The invention relates to the technical field of a DC plug, and particularly relates to a DC plug metal contact and a metal contact flat cable capable of automatically crimping. According to the DC plug metal contact, a half-ring-shaped contact plate and an inner elastic contact plate are connected with transverse connect plates through two connect plates, the connect plates are provided with wire riveting positions near the position of the transverseconnect plates, when the DC plug is produced, an interpolation core formed by the metal contact is arranged inside an insulation coat shell in an inserting mode, and the half-ring-shaped contact plate is in contact with a bare contact part of the coat shell. Two wires which are required to be connected are crimped on the riveting positions of the connect plates of the half-ring-shaped contact plate and the inner elastic contact respectively through an automatic crimping machine, and the two wires are cut on the transverseconnect plates, so that the tight connection is assured, quality problem caused by traditionally welding is avoided, and production efficiency is improved. When a DC plug flat cable is formed by a whole chain of transverse connect plates, the transverse connect plates can be formed into a tray and can be arranged on the crimping machine to automatically crimp the wires, and work efficiency is improved.
