[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention assembles J / B and FL / B by directly fixing them through a conductive material and assembling the conductive material of the fixed portion to the conductive material of J / B and FL / B. Provided is a connection structure for a branch connection box, which is characterized by using an electric connection mechanism in combination with a J / B and FL / B fixing mechanism connected to a material.

In order to fix FL / B and J / B to the cover of the branch connection box at the same time, bolts protruding from the cover are drilled in the joining pedestal of FL / B and J / B. It is preferable that the bolt hole is penetrated and tightened with a nut.

Further, for fixing / electrical connection between FL / B and J / B and for connecting FL / B power supply, an L-shaped fixing plate made of a conductive metal plate is provided, and a vertical portion of the fixing plate is provided. The FL / B fixing part is fixed to the joint seat plate consisting of the FL / B busbar together with the terminal attached to the end of the power connection wire via bolts, while the horizontal part of the fixing plate is used for J / B fixing. It is preferable that the joining pedestal is joined to a pedestal made of a J / B bus bar, the bolt holes formed in these pedestals are communicated with each other, the bolts protruding from the under cover are passed through, and the nuts are tightened and fixed. ..

[0009]

[Action]

 As described above, the FL / B and the J / B are integrally fixed and fixed in the case in the assembled state, and the case is fixed to the vehicle body, which saves space. You can Further, by the above fixing, the FL / B and the J / B can be electrically connected at the same time, and thus the conventional connection via an electric wire or a connector can be eliminated. Further, the fixing mechanism can also connect the FL / B and the power supply.

Embodiments The present invention will be described in detail below with reference to embodiments shown in the drawings. In FIG. 1, 10 is a FL / B, 11 is a J / B, and 12 is an undercover installed on the tire house of the vehicle. The FL / B 10 and the J / B 11 are housed in the under cover 12, and the nut 14 is tightened to the bolt 13 protruding from the under cover 12, thereby the J / B 11 and the FL / B 10 are joined together. It is integrally fixed inside, and at the time of fixing, the conductive materials of FL / B10 and J / B11 are brought into contact with each other for electrical connection.

A single L-shaped fixing plate 15 made of a conductive metal plate is provided for fixing and electrically connecting the FL / B10 and J / B11 and for connecting the FL / B10 and a power source. The vertical portion of the fixing plate 15 becomes an FL / B fixing portion 15a, and a fixing bolt hole 15b is formed in the center thereof. A horizontal portion bent from the upper end of the fixing portion 15a serves as a J / B fixing joint pedestal 15c, and a bolt hole 15d through which the bolt 13 penetrates is formed in the central portion thereof.

On the other hand, the FL / B 10 is provided with a fixing plate mounting seat plate 20 by a bus bar, and the FL / B fixing portion 15a of the fixing plate 15 is brought into contact with the outer surface of the seat plate 20, and the fixing portion is fixed. The terminal 22 attached to the tip of the power supply connection wire 21 is brought into contact with the outer surface of 15a, and the fixing plate 15 is fixed to the seat plate 20 of the FL / B 10 by the bolt 16.

The J / B 11 is provided with a horizontal joining pedestal 23 having a fitting recess having the same shape as the J / B fixing joining pedestal 15c of the fixing plate 15 by a bus bar. A bolt hole 23a is formed at the center of the.

When the FL / B10 and the J / B11 are assembled in the under cover 12, the pedestal 15c of the fixing plate 15 is superposed on the upper surface of the joining pedestal 23 of the J / B11, and the bolt holes 15d and 23a communicated with each other. The bolt 13 protruding from the under cover 12 is penetrated and the nut 14 is tightened from the upper end to fix the FL / B 10 and the J / B 11 and also to the inside of the under cover 12.

With the above-mentioned connection structure, the FL / B 10 is connected to a power source, and the FL / B 10 and the J / B 11 are composed of a seat plate 20 made of a bus bar, a fixing plate 15 and a bus bar of the FL / B 10. It is electrically connected via the pedestal 23.

[Effect of the device]

 As is clear from the above description, according to the present invention, the FL / B is directly fixed and assembled to the J / B, and the FL / B and the J / B are fixed to the case cover at the same time. Since this is done, the number of fixing mechanisms can be reduced and it can be placed in a narrow space.

Furthermore, since the FL / B and the power source and the FL / B and the J / B can be electrically connected together with the fixing mechanism, the electric connection work via the electric wire can be eliminated. Along with the elimination of the connectors and terminals that were required in the past, the cost can be significantly reduced.
