The present invention is a method of assembling a device employing electric ignition by comprising assembling an igniter assembly in the device, the igniter assembly having an electric igniter provided with a first electroconductive pin and a second electroconductive pin, connected to a power source
The present invention is a method of assembling a device employing electric ignition by comprising assembling an igniter assembly in the device, the igniter assembly having an electric igniter provided with a first electroconductive pin and a second electroconductive pin, connected to a power source, the method comprising steps of: forming two measurement circuits by using the first electroconductive pin and the second electroconductive pin as a measurement terminal on one end side, respectively, and using another member provided in the igniter assembly as a terminal on the other end side with a pass through a dielectric provided in the igniter assembly, measuring pure resistances and/or impedances of the two measurement circuits, respectively, by applying a high frequency thereto separately, distinguishing the first electroconductive pin from the second electroconductive pin from a magnitude relationship (difference) between the measured pure resistance and/or impedance values, and then, disposing the igniter assembly to the device such that the first electroconductive pin and the second electroconductive pin correspond to predetermined power source electrodes, respectively.

The invention claimed is: 1. A method of assembling a device employing electric ignition by comprising assembling an igniter assembly in the device, the igniter assembly having an electric igniter provided with a first electroconductive pin and a second electroconductive pin, connected to a power source, the method comprising steps of: forming two measurement circuits by using the first electroconductive pin and the second electroconductive pin as a measurement terminal on one end side, respectively, and using another member provided in the igniter assembly as a terminal on the other end side with a pass through a dielectric provided in the igniter assembly, measuring pure resistances and/or impedances of the two measurement circuits, respectively, by applying a high frequency thereto separately, distinguishing the first electroconductive pin from the second electroconductive pin from a magnitude relationship (difference) between the measured pure resistance and/or impedance values, and then, disposing the igniter assembly to the device such that the first electroconductive pin and the second electroconductive pin correspond to predetermined power source electrodes, respectively. 2. The assembly method according to claim 1, wherein the dielectric is an electric insulation cover covering an ignition portion of the electric igniter. 3. The assembly method according to claim 1, wherein the dielectric is a resin which integrally couples a metallic igniter collar to the electric igniter. 4. A method of distinguishing between a first electroconductive pin and a second electroconductive pin, provided in an electric igniter in an igniter assembly including the electric igniter, comprising steps of: forming two measurement circuits passing through a dielectric, provided in the igniter assembly, such that the first electroconductive pin and the second electroconductive pin serves as a measurement terminal on one end side and another member provided in the igniter assembly serves as a terminal on another end side; and measuring pure resistances and/or impedances of the two measurement circuits, respectively, by applying a high frequency thereto separately, and distinguishing between the first electroconductive pin and the second electroconductive pin from a magnitude relationship (difference) between the measured pure resistance and/or impedance values. 5. The method of distinguishing between a first electroconductive pin and a second electroconductive pin according to claim 4, wherein the dielectric is an electric insulation cover covering an ignition portion of the electric igniter. 6. The method of distinguishing between a first electroconductive pin and a second electroconductive pin according to claim 4, wherein the dielectric is a resin which integrally couples a metallic igniter collar to the electric igniter.
