Abstract

A tolerance absorbing structure of a first power supply distribution box includes a connection terminal to which one end part of a flat distribution member is connected and fixed; a storage case including a connection opening member into which the connection terminal is inserted and fixed to a vehicle body; an elastic support member configured to support the connection terminal freely movably in a three-dimensional direction with respect to the connection opening member; and a flexible conductor configured to connect a substrate connection part of a circuit conductor stored in the storage case and the connection terminal with an extra length.

First claim

What is claimed is:

1 . A tolerance absorbing structure of a power supply distribution box, comprising:
a conductor connection member to which one end part of a flat distribution member is connected and fixed; a storage case that includes a connection opening member into which the conductor connection member is inserted, and fixed to a vehicle body; an elastic support member that supports the conductor connection member movably in a three-dimensional direction with respect to the connection opening member; and a flexible conductor that connects a substrate connection part of a circuit conductor stored in the storage case and the conductor connection member with an extra length.

2 . The tolerance absorbing structure of the power supply distribution box according to claim 1 , wherein
the conductor connection member is constructed by a connection terminal including an electric connection part to which one end part of the flat distribution member is connected and fixed, and one end part of the flexible conductor, the other end part of which is connected to the substrate connection part, is connected to the connection terminal.

3 . The tolerance absorbing structure of the power supply distribution box according to claim 1 , wherein
the conductor connection member is constructed by a female terminal including a fitting part to which one end part of the flat distribution member is fitted, and an insulation housing for storing the female terminal, and one end part of the flexible conductor is connected to the female terminal.

4 . The tolerance absorbing structure of the power supply distribution box according to claim 1 , wherein
the connection opening member is fixed to a substrate on which the circuit conductor is formed.

5 . The tolerance absorbing structure of the power supply distribution box according to claim 2 , wherein
the elastic support member is constructed by a grommet, the grommet including a large cylindrical part mounted on an opening end of the connection opening member, a small cylindrical part mounted on the connection terminal, and a connection cylindrical part connecting the large cylindrical part and the small cylindrical part.

6 . A vehicle circuit body comprising:
a first power supply distribution box including a plurality of tolerance absorbing structures of the power supply distribution boxes described in claim 1 ; a plurality of second power supply distribution boxes fixed to the vehicle body; and the plurality of flat distribution members, one end parts of which are respectively connected and fixed to the conductor connection members in the first power supply distribution box, and the other end parts of which are respectively connected and fixed to the second power supply distribution boxes.
