Detailed Description
Embodiments of the present invention are further described with reference to fig. 1-3.
The embodiment has the specific structure that: comprises a conductive layer 1 formed by arranging a plurality of wires in parallel, and insulating films (1 a,1 b) disposed on the upper and lower sides of the conductive layer 1. Two continuous wires arranged side by side on any side in the conductive layer 1 are first wires 11 for connecting the air bags, and the distance H1 between the centers of the two first wires 111 is 2.3 mm. The remaining conductor of the conductive layer 1 connected to the steering wheel is a second conductor 12. The center distance H2 between the first wire 11 and the second wire 12 adjacent thereto is 2 mm.
Since the number of the second conductive lines 12 is larger than that of the first conductive lines 11, the width of the first conductive lines 11 is 1.2 times that of the second conductive lines 12 to improve the structural stability of the first conductive lines 11.
The transmission line has a plurality of measuring areas 10, and the conducting layer 1 in the measuring areas 10 is exposed to the outside so that a tester can directly test the resistance and the voltage of the lead in the measuring areas 10.
The conducting layer 1 in the measuring region 10 has two insulating films coated thereon, namely a first insulating section 21 and a second insulating section 22. After the transmission line is formed, a part of the insulating film in the measurement region 10 is cleaned by means of peeling and removing.
In the measuring area 10, the first insulating section 21 and the second insulating section 22 divide the conducting wire into three sections to be detected with equal length, and the conducting wires of the three sections are exposed outside; in order to ensure a stable configuration of the measurement region 10, the length of the second insulating segment 22 is set to 1/4 which is the length of the first insulating segment 21.
The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
