ELECTRICAL CONNECTING BOX AND METHOD FOR PROTECTING PRINTED CIRCUIT BOARD AND MOUNTED PARTS INSIDE THE ELECTRICAL CONNECTING BOX
First Claim
1. An electrical connecting box, comprising:
- a printed circuit board;
a first protecting member and a second protecting member housing the printed circuit board in a sandwich state;
an extended portion extending from one side of the board surfaces of the printed circuit board, and facing to the first protecting member; and
a first pillar portion formed upon an inside surface of the first protecting member facing the one side of the board surfaces;
wherein the first pillar portion is configured such that their tips, according to bending of the first protecting member, can be contacted or spaced to the one side of the board surfaces or a contacting portion fixed upon the board surface; and
when the first pillar portion is contacted to the one side of the board surfaces or the contacting portion, a predetermined clearance is given between the extended portion and the inside surface of the first protecting member.

Abstract
An electrical connecting box suitable to widely-ranging temperature conditions from high temperature to low temperature inside the engine room of a vehicle is described, having a printed circuit board 300 and a first protecting member 100 and a second protecting member 200 housing the printed circuit board in a sandwich state. In this electrical connecting box an extended portion 310 being a part of electrical parts is formed upon a board surface 301 on the side of the first protecting member of the printed circuit board. Additionally, first pillar portions 110 and a second pillar portion 120 are formed upon the inside surface of the first protecting member facing one side of the board surfaces, and a tip 111 and a tip 121 of these pillar portions, according to bending of the first protecting member, can be in either a contacted state or a spaced state with respect to the board surface 301 or, alternatively, a projecting body 321 fixed to the board surface. When the first pillar portions are contacting the one side of the board surfaces, there is a gap between the extended portion and the inside surface of the first protecting member such that they do not interfere with each other.

16. An electrical connecting box comprising:
-
a printed circuit board; a first protecting member and a second protecting member housing the printed circuit board in a sandwich state; an extended portion, being a part of electrical parts, formed extending from one side of the board surfaces of the printed circuit board that faces the first protecting member; and support means formed upon an inside surface of the first protecting member facing the one side of the board surfaces; means for forming a clearance in the state where the support means and the contacting portion are in a contacted state or the support means and the one side of the board surfaces are in a contacted state, the clearance being at least sufficient to prevent interference between the extended portion and the inside surface of the first protecting member.

17. A method for protecting a printed circuit board and a mounted part in an electrical connecting box, comprising the steps of:
-
preparing the printed circuit board; preparing a first protecting member and a second protecting member that house the printed circuit board in a sandwich state; preparing an extended portion, being a part of electrical parts and formed extending from one side of the board surfaces of the printed circuit board that faces the first protecting member; preparing a first pillar portion, formed upon the inside surface of the first protecting member, the inside surface facing the one side of the board surfaces; configuring the first pillar portion such that, their tips, according to bending of the first protecting member, can be in a contacted state or a spaced state with respect to the one side of the board surfaces or the contacting portion comprised of the projecting body fixed upon the one side of the board surfaces; and forming a clearance such that, in the state where the first pillar portions and the contacting portion are in a contacted state, the clearance is at least sufficient to prevent interference between the extended portion and the inside surface of the first protecting member.
