Therefore, in this conductive module 1, it is possible to improve the assembling workability of these components.

After the conductive module 1 is attached to the battery module 110, the first conductive part 10 and the first electrical connection part 31 of the third conductive part 30 are fastened together via the electrode terminal 122, and then the second 1 Lid 62 is attached to first storage chamber 61A in the closed position (FIGS. 6 and 7).

Specifically, the illustrated electronic component holding portion 63b includes a semi-cylindrical main body holding portion 63b1 into which the cylindrical electronic component main body 51 is inserted and fitted, and the shaft portion 52a of the _first electrical connection portion 52 is inserted. It has a first conductor holding portion 63b2 to be fitted and a _second conductor holding portion _63b3 into which the shaft portion 53a of the second electrical connection portion 53 is inserted (FIGS. 1 and 2). The electronic component holding portion 63b is formed so as to insert and fit the electronic component 50 along the direction perpendicular to the inner wall surface _63a1 of the closing portion 63a. In the electronic component holding portion 63b, the axes of the connecting portions 52b, 53b of the first and second electrical connecting portions 52, 53 are along the direction orthogonal to the inner wall surface _63a1 of the closing portion 63a, and the connecting portion 52b , 53b face the opposite side of the inner wall surface _63a1 , the electronic component 50 is inserted and fitted.

Here, the housing component 60 illustrated in this example includes an electronic component holder 66 that sandwiches and holds the electronic component 50 between itself and the electronic component holder 63b (FIGS. 1 and 2). The electronic component holder 66 is formed as a separate member from the container 61 , the first lid 62 , the second lid 63 , the first hinge 64 and the second hinge 65 . The electronic component holder 66 has two semi-disc-shaped main body holding portions 66a into which the electronic component main body 51 is inserted and fitted (FIGS. 1 and 2). The main body holding portion 66a holds the rest of the electronic component main body 51 that is not held by the main body holding portion _63b1 of the electronic component holding portion 63b. By sandwiching the electronic component 50 between the electronic component holding portion 63b of the second lid 63 and the electronic component holding body 66, positional displacement of the electronic component 50 with respect to the second housing chamber 61B is suppressed.

This electronic component holder 66 is fixed to the second lid 63 . Therefore, the second lid 63 is provided with a fixing portion 63e for fixing the electronic component holder 66 when the electronic component 50 is held between the second lid 63 and the electronic component holder 63b (FIGS. 1 and 2). 2).

Between the second lid body 63 and the electronic component holder 66, two sets of a pair of fixing part 63e and fixed part 66b are provided. The pair of fixing portion 63e and fixed portion 66b constitute, for example, a so-called locking mechanism. In this case, one of the fixed portion 63e and the fixed portion 66b is formed as a claw portion, and the other portion is formed as a hook portion to which the claw portion is caught and locked when the electronic component 50 is held. Form. Here, the fixed portion 63e is formed as a hook portion, and the fixed portion 66b is formed as a claw portion.

The electronic component holder 66 may be formed with a locking portion (not shown) that prevents the first conductive component 10 from being displaced toward the opening 61a of the first housing chamber 61A. When the second cover 63 is rotated to the closed position, the engaging portion is arranged to face the first conductive component 10 with a minute gap between the first conductive component 10 and the opening 61a. This engaging portion is formed, for example, like a claw portion. Accordingly, in this conductive module 1, there is room for size reduction by eliminating the locking portion on the housing body 61 side corresponding to the function of the locking portion of the electronic component holder 66.

The third conductive component 30 is attached to the first electrical connection portion 52 while the connecting portion 52b of the first electrical connection portion 52 is inserted through the through hole 32a of the second electrical connection portion 32 from the free end side. The second electrical connection portion 32 of the third conductive component 30 is soldered to the connecting portion 52b of the first electrical connection portion 52, taking into account the accommodation position in the second accommodation chamber 61B. The fourth conductive component 40 is attached to the second electrical connection portion 53 while inserting the connecting portion 53b of the second electrical connection portion 53 into the through hole 42a of the second electrical connection portion 42 from the free end side. . The second electrical connection portion 42 of the fourth conductive component 40 is soldered to the connecting portion 53b of the second electrical connection portion 53, taking into account the accommodation position in the second accommodation chamber 61B. After that, in this housing part 60, the second lid body 63 is assembled in the second housing chamber 61B in the closed position, and after being attached to the battery module 110, the first lid body 62 is in the closed position in the first housing chamber. 61A.
