Similarly, the three second housing parts 142 are arranged in a direction orthogonal to the direction in which the electric wires 3 are led out from the second housing parts 142. Moreover, the latching | locking part 8 latched to the case 101 of the electrical-connection box 100 is provided in the both sides | surfaces of the arrow 4 direction of the housing 4E. As shown in FIG. 11, the locking portion 8 includes a lock portion 81 protruding from the side surface of the housing 4 </ b> E, and a pair of rail portions 82 provided on both sides of the lock portion 81.

  The component connection body 1E described above constitutes a component connection module 10E shown in FIGS. The component connection module 10E is configured by stacking component connectors 1E in two stages in the arrow Y direction. Further, the upper part connector 1E is overlaid on the flat portion 47 of the lower part connector 1E.

  The electrical connection box 100 includes a case 101, a component connection module 10E attached to the case 101, a relay 2 attached to each component connection body 1E of the component connection module 10E, and covers (not shown) attached to the upper and lower surfaces of the case 101. ), Etc.

  According to the present invention, it is possible to provide the component connection module 10E that can reduce the dimension in the direction in which the relay 2 is mounted on the housing 4E (arrow Y direction) and can save the installation space. Moreover, by using this component connection module 10E for the electrical junction box 100, the height dimension (dimension in the arrow Y direction) of the electrical junction box 100 can be reduced.

  In the first to fifth embodiments described above, the example in which the relay 2 is used as an example of the “electronic component” has been described. However, the “electronic component” used in the “component connection body” of the present invention is the relay 2. Other electronic components may be used.

  In the fifth embodiment described above, the electrical connection box 100 has the component connection module 10E. However, the “electric connection box” of the present invention has at least one “component connection body”. It ’s fine.

  In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment. That is, various modifications can be made without departing from the scope of the present invention.
