Double-layer wire-to-board IDC connector
Technical Field
The invention relates to the technical field of connectors, in particular to an IDC connector from a double-layer wire to a board.
Background
IDC wire end connectors may be used for wire to board signal transmission in a variety of industries including automotive, industrial, telecommunications, and the like. SMCIDC line end connectors, double layer PIN configuration, 1.27mm apart, are used to achieve a reliable, compact plug connection. Different pair board solutions can be realized by matching different board end connector types, such as vertical type or bent angle type board end connectors. The flat cable is directly inserted into the rear plug slot of the connector, and the rear plug of the connector is closed to force the metal conductive terminal IDC clamping groove to pierce the outer cover of the flat cable and contact with a flat cable core wire, so that the circuit is conducted.
