Abstract

A cable connection device includes a first holder, a second holder and a support. The first holder is configured to hold a tip part of an end of a cable. The second holder is configured to hold an intermediate part of the end. The support is configured to support the first holder. The second holder is fixed with respect to a power feed control device body. The first holder is supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable.

First claim

The invention claimed is:

1. A cable connection device configured to connect an end of a cable to an electric apparatus, the cable connection device comprising:
a first holder configured to hold a tip part of the end;
a second holder configured to hold an intermediate part of the end; and
a support configured to support the first holder,
the second holder being fixed with respect to the electric apparatus,
the first holder being supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable,
the second holder including one or more claws disposed to be in contact with a sheath in the end of the cable, and
the second holder including one or more protrusions protruded toward the end from an inner circumferential surface of a hole of the second holder, into which the end is inserted.

2. The cable connection device of claim 1 , further comprising a cap having a tubular shape and provided to accommodate therein the first holder, the second holder and the support, wherein
the one or more claws are provided to be in contact with an inner wall surface of the cap to deform in a direction of approaching the sheath, while the second holder is accommodated in the cap.

3. The cable connection device of claim 1 , wherein
the cable includes two or more electric wires covered with a sheath, and
the first holder has two or more insertion holes into which the two or more electric wires are respectively inserted in one-to-one.

4. The cable connection device of claim 3 , wherein
the two or more insertion holes are curved or bent.

5. The cable connection device of claim 1 , further comprising a first sealing part disposed to fill a gap between the support and the electric apparatus to prevent liquid from entering through the gap.

6. The cable connection device of claim 1 , further comprising a second sealing part disposed to fill a gap between the support and the end to prevent liquid from entering through the gap.

7. The cable connection device of claim 1 , wherein
the support includes a restriction part disposed to restrict turning of the first holder along a circumferential direction of the cable.

8. The cable connection device of claim 1 , further comprising a connector configured to be removably inserted in the electric apparatus to electrically connect the cable to the electric apparatus.

9. The cable connection device of claim 1 , wherein
the electric apparatus is configured to feed power to a load through a power feeding path including the cable, and stop feeding the power to the load in response to that an abnormality is present in the power feeding path.

10. A power feed control device, comprising:
a cable;
an electric apparatus configured to feed power to a load through a power feeding path including the cable, and stop feeding the power to the load in response to that an abnormality is present in the power feeding path; and
a cable connection device configured to connect an end of the cable to the electric apparatus,
the cable connection device comprising:
a first holder configured to hold a tip part of the end;
a second holder configured to hold an intermediate part of the end; and
a support configured to support the first holder,

the second holder being fixed with respect to the electric apparatus,
the first holder being supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable,
the second holder including one or more claws disposed to be in contact with a sheath in the end of the cable, and
the second holder including one or more protrusions protruded toward the end from an inner circumferential surface of a hole of the second holder, into which the end is inserted.

11. A cable connection device configured to connect an end of a cable to an electric apparatus, the cable connection device comprising:
a first holder configured to hold a tip part of the end;
a second holder configured to hold an intermediate part of the end; and
a support configured to support the first holder,
the second holder being fixed with respect to the electric apparatus,
the first holder being supported by the second holder through the support to restrict at least movement of the cable in a pulling direction of the cable,
the cable including two or more electric wires covered with a sheath, and
the first holder has two or more insertion holes into which the two or more electric wires are respectively inserted in one-to-one,
the two or more insertion holes are curved or bent.
