2, the first and second printed circuit boards 4 and 5 are supported in a direction orthogonal to the direction in which the first and second electric connection boxes 1 and 2 are joined and combined with each other. The connection terminals 4a and 5a on the first and second printed circuit boards 4 and 5 face each other in parallel with each other, and the contact pressure on the connection terminals 4a and 5a by the electric connector 9 is a simple vertical direction. Only the pressing force is applied. Therefore, the amount of elastic deformation of the contact 7 and the electric connector 9 for obtaining a good electric connection state are described.
The setting of the mounting position is easy. In addition, the electrical connector of the present invention is not limited to the shape of the electrical connector 9 in the above embodiment, and the design can be appropriately changed based on the gist of the present invention.

せることができる。Since the relative positions of the electric connectors mounted on the electric junction box with respect to the respective printed circuit boards are determined, the position of the fitting portion may be misaligned or incorrect when the electric junction boxes are joined or united. There is no need to consider insertion prevention and the like, and the electrical connection between the printed circuit boards can be automatically completed by the operation of joining and combining the electrical junction boxes.

る。Accordingly, the electrical connection between the printed circuit boards housed in different electrical junction boxes can be realized without using a wire harness, and the first electrical junction box and the second electrical junction box can be electrically connected.
Since the electrical connection between the printed circuit boards can be automatically completed by the connection / coupling operation with the electric connection box, the work efficiency of the connection / coupling operation between the electric connection boxes can be improved. Furthermore, since the wiring harness is not used for the electrical connection between the printed circuit boards, the extra length of the wiring harness may touch the surrounding box walls or the electric / electronic components contained in the electric connection box due to the vibration of the vehicle or the like. It is also possible to prevent the generation of abnormal noise caused by the noise.
