ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a wire holding structure of an electric wire protector, wherein the electric wire is prevented from protruding from a protector body through which the electric wire is put.
2. Description of the Related Art
FIG. 7
shows a conventional electric wire protector in use for protection of a wiring harness.
This electric wire protector
51
consists of a gutter-like protector body
52
of synthetic resin in a crank shape and a cover
53
of synthetic resin to cover a top opening of the protector body
52
.
The wires
54
are arranged inside the protector body
52
, the cover
53
is engaged with the protector body
52
by a set of engaging means
55
,
56
, and the wire
54
is protected from the outside. This electric wire protector
51
is used for such a place as a portion under a vehicle floor which is likely to receive strong external force.
With respect to the electric wire protector
51
, however, the wire
54
is likely to rise or protrude over a sidewall
58
of the protector body
52
at a bent portion (i.e. a cross portion)
57
when tensile force acted on the wire
54
, as shown in
FIGS. 8A
,

B.
And, this requires. an additional work of putting the wire
54
inside the protector body
52
; that is, this requires troublesome work and causes poor workability. And, since the wire
54
would not be settled, length of the wire
54
could not be decided. Further, if the cover
53
(
FIG. 7
) is put on and tightened, the wire
54
would be damaged.
On the other hand,
FIG. 9
shows another prior art electric wire protector, which is used for a battery connection plate for an electric vehicle, disclosed in Japanese Patent Application Laid-open No. 11-120986. This electric wire protector
61
is formed by insert-molding a plurality of wires
62
in resin, i.e. a resin body
63
.
This electric wire protector
61
consists of a central main portion
64
and a plurality of branch portions
65
on both sides of the main portion
64
. The wires (the mains)
62
are gathered and led out from the resin body
65
. A terminal
66
is pressure-welded to the end portion of the wire (the branch)
62
at a branch portion
63
, and an electrically contacting portion
67
, in a generally square plate, of the terminal
66
is exposed to the outside of the resin body
63
. A fuse connecting portion of the terminal
66
is exposed inside a frame portion
68
of the resin body
63
.
A fuse (not shown) is to be connected to the fuse connecting portion, and therefore the electrically contacting portion
67
is connected to the wire
62
through the fuse. One electrode
70
of a battery
69
(
FIG. 11
) is inserted into the electrically contacting portion
67
, and the wire
62
is connected to a voltage detector (not shown).
FIG. 10
shows a battery connection plate
72
which is formed by insert-molding the electric wire protector
61
(
FIG. 9
) inside a second resin body
71
. The wires (the main portions)
62
are led out from one end of a plate body, i.e. the resin body
71
. Before the above insert-molding, a busbar
90
of conductive metal in a rectangular shape is connected to the electrically contacting portion
67
of the voltage-detective terminal
66
(FIG.
9
).
Two holes
73
are provided on the busbar
90
, and a male-threaded electrode
70
of each battery
69
(
FIG. 11
) is inserted into each of the holes
73
and screwed with a nut (not shown). By means of the busbar
90
, two neighboring batteries
69
are connected in series. The electrically contacting portion
67
of the above terminal
66
(
FIG. 9
) is connected to one hole
73
of the busbar
90
with the nut. Another busbar
74
having one hole is arranged on an end side of the battery connection plate
72
, and an electric wire for power feeding (not shown) is connected to the busbar
74
.
Referring to
FIG. 11
, the above battery connection plate
72
is connected to the electrode
70
of the cylindrical battery
69
, and another battery connection plate
75
is connected to the other electrode
76
of the battery
69
.
The battery connection plates
72
,
75
are tightly-connected to the electrodes
70
,
76
with nuts in a state of the battery
69
being set inside a holder
78
having a plurality of circular holes
77
. The holder
78
is fixed to a vehicle body with bracket
79
, bolts
80
, or the like. The terminals
66
are arranged on the battery connection plate
72
, and the wires
62
continuing from the terminals
66
are led out to the outside.
However, with respect to the above conventional electric wire protector
61
(FIG.
9
), when the wires
62
are insert-molded inside the resin body
65
, positioning work of the wires
62
is troublesome. And, since the wires
62
are immersed in hot resin during the insert-molding, a measure for heat shall be taken on the insulative covers of the wires
62
, thereby increasing the cost.
On account of the above, Japanese Patent Application Laid-open No. 2000-123802 discloses an electric wire protector wherein a cover made of synthetic resin is closed to secure the wires (not shown) after the wires have arranged inside the protector body.
With respect to this electric wire protector, however, since the wires
62
are arranged flat in parallel each other similarly to the electric wire protector
61
of
FIG. 9
, the electric wire protector is relatively flat, and therefore, similarly to the electric wire protector
51
of
FIG. 7
, the wires are likely to rise at a bent portion (i.e. a cross portion) of the protector body during the arrangement work of thereof, whereby the wires are likely to protrude to the outside over the sidewall of the protector body.
This causes poor workability for wiring. And, if the cover is put on and tightened, the wires would be damaged. Further, when the electric wire protector is covered with a resin material
71
as shown in
FIG. 10
, the protruded portions of the wires are immersed in a hot condition. Still further, since strong tensile force cannot be given to the wires, the wires could not be arranged in order around the cross portion of the protector body, thereby length of the wires can not be settled.
SUMMARY OF THE INVENTION
In view of the foregoing, an object of the present invention is to provide a wire holding structure of an electric wire protector, wherein protrusion of the wires from the cross portion of the electric wire protector is prevented securely, arrangement workability of the wires is improved, damage of the wires can be prevented, and length of the wires can be pre-settled.
In order to achieve the above object, as a first aspect of the present invention, a wire holding structure of an electric wire protector comprises: a protector body having two or more wire putting-through portions, at least one of the wire putting-through portions crossing the other thereof and forming at least one cross portion; a cover to cover the protector body; and a wire to be arranged inside the protector body, wherein a nail for preventing protrusion of the wire projects inward from the cross portion.
As a second aspect of the present invention, a wire holding structure of an electric wire protector comprises: a protector body having two or more wire putting-through portions, at least one of the wire putting-through portions crossing the other thereof and forming at least one cross portion; a cover to cover the protector body; and a wire to be arranged inside the protector body, wherein a pin for preventing protrusion of the wire projects upward from a top of the cross portion.
As a third aspect of the present invention, in the structure with the above first or second aspect, a wire separating rib stands from a bottom wall of each of the wire putting-through portions with a space between an end of the wire separating rib and the cross portion.
As a fourth aspect of the present invention, in the structure with any one of the above aspects, the electric wire protector in a state of accommodating the wire is insert-molded in resin, the electric wire pro
