主权项

1. A packaging board of a type having board terminals soldered on a printed board, comprising:
an insulation support member made of a resin disposed on a printed board, the insulation support member including: (i) tubular support portions that receive board terminals wherein the board terminals have a crank-like shape; (ii) visual recognition windows on a top surface of the insulation support member so that soldering portions of the board terminals are visually recognizable by looking through the top surface of the insulation support member when the board terminals are inserted into the printed board; and (iii) a plurality of engaging portions that each engage a portion of the board terminal that extends through the insulation support member such that each engaging portion directly interfaces with one of two opposite sides of the portion of the board terminal that extends through the insulation support member, the engaging portions defining insertion amounts of the board terminals.
