FLEX-RIGID WIRING BOARD AND METHOD FOR MANUFACTURING THE SAME
First Claim
1. A protection element including:
- a soluble conductor which is disposed on an insulation baseboard and is connected to an electric power supply path of a device targeted to be protected, to cause a blowout by means of a predetermined abnormal electric power;
an insulation cover which is mounted on the baseboard with the soluble conductor being covered via a predetermined space; and
a flux which is coated onto a surface of the soluble conductor and is positioned in the space,the protection element being adapted for, in case that the abnormal electric power is supplied to the device targeted to be protected, allowing the soluble conductor to blow out and shut off a current path thereof,wherein an opening portion made of a through hole is formed at the insulation cover in opposite to the soluble conductor;
the flux comes into contact with a peripheral edge part of the opening portion; and
the flux is provided on the soluble conductor so as to be retainable at a predetermined position in the space.

Abstract
A protection element is provided which is capable of stably retaining a flux on a soluble conductor at a predetermined position and is capable of checking a retention state of the flux, enabling a speedy blowout of the soluble conductor in the event of an abnormality. This protection element includes: a soluble conductor 13 which is disposed on an insulation baseboard 11 and is connected to an electric power supply path of a device targeted to be protected, to cause a blowout by means of a predetermined abnormal electric power; a flux 19 which is coated onto a surface of the soluble conductor 13; and an insulation cover 14 which is mounted on the baseboard 11 with the soluble conductor 13 being covered therewith. The insulation cover 14 is provided with an opening porting 20 made of a through hole which is opposite to the soluble conductor 13. The flux 19 comes into contact with a peripheral edge part of the opening portion 20, retaining the flux 19 at a predetermined position on the soluble conductor 13.
