Abstract

In a case of a power distribution branch unit used in a vehicle or the like, one end of a branch wiring is connected to an exposed part of a main covered cable (a part where a core wire is exposed without an insulation cover). Branch couplers are connected to the other ends of the branch wiring and fixed to the case so as to be exposed to an outside. At least one retainer is disposed inside a hole part that is formed in the case and fixes the main covered cable.

First claim

What is claimed is:

1. A power distribution branch unit comprising:
a case;
at least one main covered cable configured to penetrate through the case and including an exposed part where a core wire is exposed without an insulation cover inside the case;
a branch wiring disposed inside the case and having one end connected to the exposed part of the main covered cable;
a branch coupler connected to another end of the branch wiring and fixed to the case so as to be exposed to an outside; and
at least one retainer disposed inside a hole part that is formed in the case and configured to fix the main covered cable, wherein:
the main covered cable comprises a plurality of main covered cables;
the retainer is disposed one on each side of the exposed part; and
each retainer is configured to fix the plurality of main covered cables.

2. The power distribution branch unit according to claim 1 , wherein the retainer includes a case contact part directly supported by the case and a grommet contact part supported by the case through a grommet.

3. The power distribution branch unit according to claim 1 , wherein the power distribution branch unit includes an internal fixing member configured to fix the main covered cable to the case without being in contact with the core wire inside the case.

4. A power distribution branch unit comprising:
a case;
at least one main covered cable configured to penetrate through the case and including an exposed part where a core wire is exposed without an insulation cover inside the case;
a branch wiring disposed inside the case and having one end connected to the exposed part of the main covered cable;
a branch coupler connected to another end of the branch wiring and fixed to the case so as to be exposed to an outside; and
at least one retainer disposed inside a hole part that is formed in the case and configured to fix the main covered cable, wherein:
on an outer peripheral surface of the retainer, a retainer-side tapered surface that inclines so as to separate from the main covered cable toward an outside of the power distribution branch unit is formed; and
on an inner peripheral surface of the case, a case-side tapered surface disposed in a pressed state on the retainer-side tapered surface is formed.

5. The power distribution branch unit according to claim 4 , wherein the retainer includes a case contact part directly supported by the case and grommet contact part supported by the case through a grommet.

6. The power distribution branch unit according to claim 4 , wherein the power distribution branch unit includes an internal fixing member configured to fix the main covered cable to the case without being in contact with the core wire inside the case.

7. A power distribution branch unit comprising:
a case;
at least one main covered cable configured to penetrate through the case and including an exposed part where a core wire is exposed without an insulation cover inside the case;
a branch wiring disposed inside the case and having one end connected to the exposed part of the main covered cable;
a branch coupler connected to another end of the branch wiring and fixed to the case so as to be exposed to an outside; and
at least one retainer disposed inside a hole part that is formed in the case and configured to fix the main covered cable, wherein:
the retainer includes a first half body and a second half body;
the first half body includes a claw part; and
the second half body includes a depressed part configured to entirely house the claw part, and a raised part formed inside the depressed part and configured to engage with the claw part.

8. The power distribution branch unit according to claim 7 , wherein the retainer includes a case contact part directly supported by the case and a grommet contact part supported by the case through a grommet.

9. The power distribution branch unit according to claim 7 , wherein the power distribution branch unit includes an internal fixing member configured to fix the main covered cable to the case without being in contact with the core wire inside the case.

10. A vehicle including a power distribution branch unit, an engine, a travel motor, an energy storage device, a power conversion device, and an electric auxiliary machine,
the power distribution branch unit comprising:
a case;
at least one main covered cable configured to penetrate through the case and including an exposed part where a core wire is exposed without an insulation cover inside the case;
a branch wiring disposed inside the case and having one end connected to the exposed part of the main covered cable;
a branch coupler connected to another end of the branch wiring and fixed to the case so as to be exposed to an outside; and
at least one retainer disposed inside a hole part that is formed in the case and configured to fix the main covered cable, wherein:
the main covered cable of the power distribution branch unit is configured to connect the energy storage device and the power conversion device;
the branch coupler and the electric auxiliary machine are connected by an auxiliary machine wiring; and
the power conversion device is configured to convert power from the energy storage device and supply the converted power to the travel motor.

11. The vehicle according to claim 10 , wherein the power distribution branch unit is disposed on a dashboard of the vehicle.
