Adapter with an insulating body having a circuit board with a plurality of conductive modules surface mounted on the board

An adapter assembly, comprising a plurality of adapters arranged in one row, wherein each of the adapters includes:

• an insulating body including an internal connecting portion and an external connecting portion connected to the internal connecting portion;
• two circuit boards separately arranged in the insulating body;
• and
• a plurality of conductive modules arranged in the insulating body and respectively disposed on two opposite sides of the two circuit boards, wherein each of the conductive modules includes a plastic member and a plurality of conductive terminals arranged in one row, wherein each of the conductive terminals has an embedded segment embedded in the plastic member, a fixing segment extending from an end of the embedded segment, and a contacting segment extending from an opposite end of the embedded segment,
• wherein in each of the adapters, the fixing segments of the conductive modules are soldered on the two circuit boards by using a surface mounting technology (SMT) manner,
• wherein the internal connecting portions of the adapters are connected to each other to form as one piece.
