Problems solved by technology
However, the cost of the connector 41 is high, and the connection of the deepest narrow part requires a jig for positioning the connector.
[0005] In addition, on the latter ion electrode 51, the lead wire on the sensing part side of the sensor is composed of the lead wire core wire 53 drawn from the corresponding film 50 and the lead wire core wire 54 connected to the output lead wire 40, but the lead wire core wire 42 of the output lead wire 40 and the lead wire The core wire 54 is soldered at the connection part A, and the lead wire core wire 53 and the lead wire core wire 54 are soldered at the connection part B, so skilled soldering operations are required
Moreover, since the heat of soldering is transferred to the insulating layer 52 or the corresponding film 50, it becomes a cause of deterioration of insulation and deterioration of the corresponding film 50.

Embodiment Construction
[0012] figure 1 It shows an embodiment of this invention, and it is constituted by using an ion electrode (glass electrode) 31 for measuring pH, etc., and transmitting the signal of the internal electrode 38 to the conductive fiber layer 1 that is deposited directly into the conductive fiber layer 1. The fiber layer 1 and the like output the lead wire core wire 42 of the lead wire 40 . and also, figure 1 neutralize image 3 , Figure 4 The same and equivalent symbols used in the same symbol are the same or equivalent objects.
[0013] The aforementioned ion electrode 31' has a glass corresponding membrane 32 at the bottom of a glass support tube 34 filled with internal liquids 33 such as KCl. While the aforementioned support tube 34 is filled with a bushing 35 made of elastic material such as silicone rubber, the upper part of the bushing filling position is filled with an insulating member 36 made of silicone resin. Furthermore, in the state where the inner electrode 33...

The invention provides an electrical connection method between the sensing part of a sensor and an output lead wire. The method can perform electrical connection between the output lead wire and the lead wire of the sensor sensing part side in a narrow place simply, reliably and at low cost. The present invention is characterized in that the output leads are connected to the lead wires of the sensing part of the sensor through the conductive fiber layer accumulated by the conductive fibers.
Description
technical field [0001] The present invention relates to the electrical connection method between the sensing part of the sensor and the output lead. Background technique [0002] When measuring the concentration of ions such as pH in a solution, an ion electrode with a sensor sensing part that senses the ions to be measured and generates a potential is used. image 3 An ion electrode (glass electrode) 31 using, for example, a glass membrane is shown as the corresponding membrane (refer to Japanese Utility Model Publication No. 6-10311). The ion electrode 31 has a glass responsive membrane 32 at the bottom of a glass support tube 34 filled with liquid 33 . A bushing 35 made of elastic material is filled in the support pipe 34, and an insulating member 36 is filled at the upper part of the bushing filling position. And in the state of being connected to the inner stage 33a soaked in the inner liquid 33, the lead core wire (for example, Ag silve...
