  However, in such a structure, in the assembly process including electrical connection, the connection substrate is inserted while sliding in the thickness direction with respect to the pattern exposed in the holes parallel to the thickness direction. There is a concern about electrical failure due to friction between the connection substrate and the pattern, and a decrease in reliability becomes a problem. At the same time, since an ECU board having a pattern for drawing wiring from the ECU is separately provided, the number of parts is increased and the assembly process is inefficient.

  In addition, since the ECU board dynamically supports the ECU and also has a pattern for pulling out the wiring of the ECU, the reliability of the ECU board as a single component with a mixture of dynamic functions and electrical functions. There is also a problem of lowering. Furthermore, since this pattern is exposed to the outside of the ECU casing, there is a concern about electrical problems due to rainwater, dust, and magnetic intrusion, which also causes a problem that reliability is lowered.

  For this reason, the structure described in Patent Document 1 is particularly useful when the on-board equipment is centrally mounted by connecting a distribution box that performs distribution or signal distribution to the ECU to the storage box described above. There is a problem that it cannot be said that the electrical connection between the boxes is more appropriate as a structure for performing the electrical connection more efficiently and based on high reliability.

  That is, as with the first connectors 2a, 3a, 4a and the second connectors 7a, 7b, 7c, the electrical connection between the connector block 7 and the junction box 6 can be realized using general-purpose components. When the connector block 7 has been inserted into the insertion hole 5j, the fitting of the third connector 7d to the fourth connector 6c has been completed. Since the pins included in the four connectors 6c are not exposed to the outside and can be sealed from the outside, an electrical failure due to intrusion of rainwater, dust, and magnetism can be prevented and reliability can be improved.

  In addition, in the electronic device housing structure 1 of the present embodiment, the arrangement direction of the plurality of pins provided in the second connectors 7a, 7b, 7c and the third connector 7d is indicated by R in FIG. 4 and in FIG. Since the direction perpendicular to the second direction indicated by Fr, that is, the vertical direction indicated by UP in FIG. 4, is provided, the following advantageous effects can be obtained.

Since a pattern for electrically connecting a plurality of pins may be used, the pattern 7i can be a plurality of parallel lines parallel to the UP in FIG. As a result, a plurality of patterns 7i can be formed on the same plane with respect to the plurality of pins 7h, so that the configuration of the connector block 7 can be simplified by using the single substrate 7e. Thereby, the electronic device housing structure 1 can be further simplified as follows.

  That is, as described above, the second connectors 7a, 7b, and 7c can be mounted on the surface having the pattern 7i of the substrate 7e.

  Furthermore, in the electronic device housing structure 1 of the present embodiment, the connector block 7 includes a base 7g that holds the board 7e, and a cover 7f that is fitted to the base 7g and covers the board 7e in a sealed manner.

Only when it is inserted into the hole 5j, the insertion work and the fitting work of the third connector 7d to the fourth connector 6c can be completed.

  In other words, after the insertion work of the connector block 7 in the first direction, the assembly direction in which the second connectors 7a, 7b, 7c of the connector block 7 are directed becomes the direction directed to the back side of the box-in-box 5.
