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 a board surface of the printed circuit board, and facing the first protecting member;
a first pillar portion formed upon an inside surface of the first protecting member and facing the one side of the board surface, a tip of the first pillar portion having a clearance with the one side of the board surface when the first protecting member undergoes no bending;
a second pillar portion that faces the printed circuit board, extends to the printed circuit board and is placed on an inside surface of the second protecting member;
an engaging portion extending from the second protecting member and engaging the first protecting member;
a first hole portion, formed in the first protecting member, that guides and fixes the engaging portion through the first pillar portion; and
a second hole portion, formed in the printed circuit board, that is configured to be penetrated by the engaging portion, whereinthe first pillar portion is configured such that the tip of the first pillar portion, upon the bending of the first protecting member, contacts the board at the one side of the board surface or at a contacting portion fixed on the board surface;
the engaging portion penetrates the second hole portion in the printed circuit board and the first hole portion in the first pillar portion and engages the first protecting member,the second pillar portion, in a location corresponding to where the first pillar portions contact the printed circuit board, contacts a reverse-side board surface of the printed circuit board which faces the second protecting member, andwhen the first protecting member is bent towards the printed circuit board, the tip of the first pillar portion contacts the board at the one side of the board surface or at the contacting portion, such that a gap exists 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.
