The connection part 7 and the terminal box 4
Between the bottom wall and the lid 3 is a fixed-shaped polymer material 21 having a vibration-absorbing and insulating property, formed of a plate having a size large enough to fit urethane foam, styrofoam or the like into the terminal box 4. , 22 are interposed. These polymer materials are divided into an inner side and an outer side at a surface including a lead-in port of the external connection line 6 into the terminal box, and a concave portion for sandwiching the external connection line 6 and the connection portion 7 is provided on this division surface. The inner polymer material 21 is provided with a lead-out hole 21a for leading out the lead wire 5. When the cover 3 is fastened to the box 1a with the screws 23, the connecting portion 7 is sandwiched between the polymer materials 21 and 22 and is supported in the terminal box 4 by vibration isolation.

又は接地事故を起こす恐れもあった。However, in FIG. 5, when assembling the connecting portion 7 into the recess 31b and pressing the outer polymer material 22 against the outer polymer material 22,
Due to the elasticity of the surface (divided surface) of the inner polymer material 31 between the extraction hole 31a and the recess 31b, the extraction line 5 and the external connection line 6 that hit this surface portion are lifted, and the connection fitted into the recess 31b. There is a risk that the part 7 will also come off. Even if it comes off, it is hard to see when the outer polymer material 22 is pressed, so it is difficult to work while looking in the horizontal direction. In the worst case, they may be assembled while detached, and may be used for vibration-resistant electrical equipment. Therefore, there is a possibility that short-circuiting or grounding accidents may occur due to vibration of the connecting parts or the box 1a.

1は接続部７の高さA2より小さいが、幅B1が前記の条件
を満せば必ずしも深さA1はA2より小さくなくてもよい。In the figure, an intermediate polymer material 43 is interposed between a flat outer polymer material 22 and an inner polymer material 41, all of which are housed in the same terminal box as the conventional example, and the intermediate polymer material 43 is Adhere to the inner polymer material 41. Withdrawal hole 41a in inner polymer material 41
The intermediate polymer material 43 is provided with a common groove 43a so as to surround the drawer hole 41a, and each of the grooves 43b for the connecting portion 7 continuous with the common groove 43a is provided. Width B 1 of the groove 43b is smaller than the width of the connecting portion 7, it is strongly fixed by the elasticity of the intermediate polymeric material if fitted into the connecting portion 7. Groove 43b depth A
1 is smaller than the height A 2 of the connecting portion 7 is not necessarily depth A 1 if the width B 1 is Mitsuruse the condition may be less than A 2.

で形成したり、内側高分子材41と中間高分子材43とを一
体形成すると量産性がよい。If the hardness of the intermediate polymer material 43 is higher than that of the inner polymer material, the fixing of the connection portion 7 is ensured. However, the intermediate polymer material 43 may be formed of the same material, or the inner polymer material 41 and the intermediate polymer material 43 may be combined. When integrally formed, mass productivity is good.
当然に溝43bの間隔は絶縁距離と沿面距離を満足する

る。Naturally, the interval between the grooves 43b needs to satisfy the insulation distance and the creepage distance, and the common groove 43a is not provided.
It suffices to continue to a. At this time, the portion of the external connection line 6 extending from the extraction hole 41a to the outside of the terminal box rides on the groove-free surface (divided surface) of the intermediate polymer material 43.
It is fixed by 43b, and does not come off when the outer polymer material 22 is pressed, but rather improves the whole fixation after the assembly is completed.
