In addition, the edge position groove 15 is formed as a double concentric circle eccentric to form a stepped section. Therefore, the diameter d of the mail flange 53 has a relationship that can be somewhat constricted relative to the diameter D of the edge position groove 15. The setting depth of the edge position groove 15 is set such that the signal processing unit 40 assembled in the signal processing unit housing 50 is inserted into the inner connector 30 after the mail flange 53 of the signal processing unit housing 50 is fitted.

For example, the terminal inlet groove 31a may have an inverted triangular cross section, and the signal processing section hook groove 31b may have a rectangular cross section. Generally, the number of the assembly holes of the inner connector 30 is formed in accordance with the number of the external connector terminals of the external connector terminal 20.

3, detailed structures of the signal processing unit 40 and the signal processing unit housing 50 are illustrated.

However, the signal processing unit 40 includes three first, second, and third hooks 41-1, 41-2, and 41-3 protruding from the substrate. Each of the first, second and third hooks 41-1, 41-2 and 41-3 is made of an elastic material having a split structure, The terminal ends 21-1a forming the respective end portions of the terminal ends 21-1, 21-2, and 21-3 may be fitted and fixed. Usually, the number of hooks of the signal processing unit 40 is formed in accordance with the number of external connector terminals of the external connector terminal 20 or the number of the assembly holes of the inner connector 30.

Specifically, the signal processing unit housing 50 is formed with a stepped step 51 inside the body to form a double-concentric circular uni-directionally accommodated space, and a stepped male flange 53 integrally formed with the stepped step 51 do. A signal processing unit 40 is seated on the step jaw 51 and the mail flange 53 is fitted into the edge position groove 15 formed in the female flange 13 of the external connector 10. Therefore, the diameter d of the mail flange 53 has a relationship that can be somewhat constricted relative to the diameter D of the edge position groove 15. The insertion length of the mail flange 53 of the signal processing unit housing 50 is equal to the set depth of the edge position groove 15 of the external connector 10 so that the mail flange 53 is inserted into the edge position groove 15 The signal processing unit 40 assembled in the signal processing unit housing 50 can be assembled with the inner connector 30 together.

In the case of the first type process, the setting of the inner connector 30 and the external connector terminal 20 is performed as in S21, but the process goes to S30 if the process is not the first type process. The first type process is illustrated in FIG. 5, wherein the inner connector 30 and the external connector terminal 20 are set first. In particular, the setting work of the inner connector 30 and the external connector terminal 20 is extremely simple. For example, each of the first, second, and third external connector terminals 21-1, 21-2, and 21-3 of the external connector terminal 20 is connected to the first, 31-2, 31-3, 31-1, 31-2, 31-3, respectively.

As a result, the assembly is completed in a state where the inner connector 30 and the signal processing unit 40 are connected as shown in S60 do. More specifically, the mail flange 53 of the signal processing unit housing 50 is fitted into the edge position groove 15 which is broken into the female flange 13 of the external connector 10, The first and second and third hooks 41-1, 41-2, and 41-3 of the signal processing unit 40 by the mail flange 53 entering the set depth of the edge position groove 15 of the external connector 10, The terminal ends 21-1a of the first, second and third external connector terminals 21-1, 21-2, and 21-3 are fitted and strongly fixed. The external connector 10 and the signal processing unit housing 50 maintain a strong fixed state due to the relationship between the diameter d of the mail flange 53 and the diameter D of the edge position groove 15. [

Therefore, the assembling process of the sensor assembly 1 by the first type process is performed by the signal processing unit 40 and the signal lead wires including the first, second and third external connector terminals 21-1, 21-2, There is an advantage in that all of the problems such as the excessive quality of soldering and poor quality of the brazing of the soldering soldering which is soldered to each other, and the problem of breakage of the solid-state signal processing unit 40 of the press-fit to apply the overload to the signal processing unit are solved.

Meanwhile, S30 is a second type process, which sets the inner connector 30 and the signal processing unit 40 as in S31. The second type process is illustrated in FIG. 6, wherein the inner connector 30 and the signal processing unit 40 are first set. In particular, the setting work of the inner connector 30 and the signal processing unit 40 is extremely simple. For example, the first, second, and third hooks 41-1, 41-2, and 41-3 of the signal processing unit 40 are connected to the first, second, and third assembly holes 31-1 , 31-2, 31-3) in the signal processing section hook grooves 31b.

Subsequently, when the second type process of S30 and S31 is completed, the signal processing unit housing 50 and the signal processing unit 40 are assembled by switching to S40. With this assembly, the signal processing unit 40 is integrated with the signal processing unit housing 50 using the stepped step 51 of the signal processing unit housing 50. Subsequently, the signal processing unit housing 50 and the external connector 10 are assembled by switching to S50. As a result, the assembly is completed in a state where the inner connector 30 and the signal processing unit 40 are connected as shown in S60 do.

The assembling process of S40 to S60 following the second type process is the same as the assembling process of S40 to S60 described after the first type process of S20 and S21, and thus will not be described.

Therefore, the assembling process of the sensor assembly 1 by the second type process is also performed on the signal lead 40 including the signal processing unit 40 and the first, second and third external connector terminals 21-1, 21-2, There is an advantage in that all of the problems such as the excessive quality of soldering and poor quality of the brazing of the soldering soldering which is soldered to each other, and the problem of breakage of the solid-state signal processing unit 40 of the press-fit to apply the overload to the signal processing unit are solved.
