<p><P>PROBLEM TO BE SOLVED: To provide a unit with built-in electronic parts which has a short-circuit preventing function. <P>SOLUTION: When a short-circuit preventing cover 101 is attached, a bottom wall facing part 104 of the short-circuit preventing cover 101 covers welding holes 102 and 103 in the bottom wall 58 of a case 28, and also a U-shaped sidewall facing part 105 of the short-circuit preventing cover 101 covers a projection stopper in the sidewall 59 of the case 28. Accordingly, the section covered with the short-circuit preventing cover 101 is isolated from the outside. Inside a recess 57 for engagement, the welding part between a lead 68 of electronic parts and a connecting leg 80 of an earth terminal 31 is covered with the insert of the short-circuit preventing cover 101 to be protected. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
