Connector and manufacturing method thereof

A method of manufacturing a connector, comprising:

• providing a first mold and a second mold matching the first mold, the first mold and the second mold together forming at least one chamber there between, the first mold having a plurality of pins, the second mold having a plurality of slots which allow the respective pins to insert into through the chamber along an inserting direction, the chamber being tilted relative to the inserting direction, the second mold having a receiving surface which has a low end and a high end, the slots penetrating through the receiving surface, each of the slots having a first sidewall and a second sidewall opposite to the first sidewall, the first and second sidewalls respectively being close to the low end and the high end, the receiving surface having a plurality of positioning structures adjacent to at least one of the respective sidewalls of the respective slots;
• filling up the chamber with an insulating material to allow the insulating material to enclose the pins so as to form a plurality of terminal holes;
• obtaining an insulating casing after the insulating material is solidified, wherein the terminal holes are arranged to pass through the insulating casing in a manner to be tilted to the insulating casing, the insulating casing further having a plurality of positioning parts at locations corresponding to the respective positioning structures;
• and
• arranging the terminals within the respective terminal holes.
