Description
This invention relates to a lever-type connector used
for connecting a connector, mounted on an end portion of a wire
harness, to a mating connector, a wire harness-mounting
structure and a wire harness-removing method, using this
connector, and more particularly the invention relates to
these techniques which facilitate the recycling.
As is well known, electric connection boxes, such as a
junction box (J/B), a relay box (R/B) and an electronic control
unit box (ECU/B), are mounted on an automobile to form circuits
for connecting wire harnesses to electrical equipments. Such
electric connection box has electric circuits (formed by
metallic bus bars), such as a power distribution circuit,
contained in a casing thereof, and a plurality of
connector-connecting portions each for electrical connection
to a connector, mounted on an end portion of the wire harness,
are formed on the outside of the casing.
On the other hand, recently, the environmental problem
has received wider appreciation, and the effective recycling
of the resources has become a large problem to be solved. With
respect to such a problem, even discarded automobiles are not
an exception. The amount of wire harnesses, used in recent
electronically-controlled automobiles, are vast, and the
recycling of these wire harnesses can not be ignored in the
existing circumstances.
Here, an example of a conventional connector-connecting
structure in an electric connection box or the like will be
schematically described with reference to Figs. 1 and 2. In
these Figures, a connector portion 2 is mounted on a distal
end of a wire harness 1. On the other hand, a
connector-connecting portion 4 is formed on the electric
connection box 3, and the connector portion 2 can be received
in the interior 5 of this connector-connecting portion. A
retaining claw 6 is provided at the connector portion 2, and
the connector-connecting portion 4 has a retaining hole 7 for
engagement with the retaining claw 6 to prevent the
disengagement of the connector portion 2.
Incidentally, for removing a wire harness from a vehicle
body to recover it at the time of disassembling a discarded
vehicle, a lifting machine, such as a crane, is used, and in
this case a J-shaped hook of the machine is brought into
engagement with the wire harness, and is lifted so as to remove
the wire harness. This is schematically shown in Fig. 3. In
this Figure, reference numeral 8 denotes the J-shaped hook
provided at the lifting machine such as a crane, and reference
numeral 9 denotes the vehicle body. In the case where the
connection between the connector portion 2 of the wire harness
1 and the connector-connecting portion 4 of the electric
connection box 3 was very firm, the wire harness 1 was cut off
when removing the wire harness, and part of the wire harness
failed to be recovered, and therefore the problem with this
method was the recovery rate.
There is known another conventional connecting
structure using a lever-type connector. An example of such
lever-type connector is schematically shown in Figs. 4 to 6.
Fig. 4 is a perspective view of the lever-type connector,
showing a condition before the connection is effected, Fig.
5 is a partly-broken view as seen from the side, Fig. 6A is
a view similar to Fig. 5, but showing the process of the
connecting operation, and Fig. 6B is a view similar to Fig.
5, but showing the connected condition.
In these Figures, a connector portion 12 is mounted on
a distal end of a wire harness 11. On the other hand, a
connector-connecting portion 14 is formed on an electric
connection box 13, and the connector portion 12 can be received
in the interior 15 of this connector-connecting portion. A
lever piece 15 is pivotally mounted on the connector portion
12 by pin members 16, and cam members 17 are mounted on the
connector portion 12. Cam grooves 18, corresponding
respectively to the cam members 17, are formed in the lever
piece 15. On the other hand, channel-shaped grooves 19 and
channel-shaped grooves 20 are formed in inner surfaces of the
connector-connecting portion 14 of the electric connection box
13, and the grooves 19 guide the pin members 16, respectively,
and are engaged respectively with the pin members 16 when the
connector portion 12 is connected to the connector-connecting
portion, and the grooves 20 guide the cam members 17,
respectively, and are engaged respectively with the cam
members 17 when the connector portion 12 is connected to the
connector-connecting portion.
In the above construction, the connector portion 12,
connected to the distal end of the wire harness 11, is inserted
into the connector-connecting portion 14, with the lever piece
15 held in a released condition (in an upper position) , as shown
in Fig. 5. At the time of insertion of the connector portion
12, the pin members 16 are fitted respectively into the grooves
19 in such a manner that the cam members 17 move along the
grooves 20, respectively. When the connector portion 12 is
inserted to a certain degree, each pin member 16 reaches a
lowermost portion of the corresponding groove 19 (Fig. 6A),
and thereafter the lever piece 15 is pivotally moved right about
the pin members 16 each held in this lowermost portion, and
therefore each cam member 17 moves in accordance with the
configuration of the cam groove 18. Finally, the lever piece
15 is brought into a recumbent condition as shown in Fig. 6B,
and the connected condition is achieved, thus completing the
connection of the connector portion 12 to the
connector-connecting portion 14.
In the above construction, for disconnecting the
connector portion 12 from the connector-connecting portion 14,
the operator pulls the lever piece 15 up with the hand, so that
the connection is canceled, and therefore the connector
portion can be disconnected.
Even in the above conventional lever-type connector,
however, when a pulling force is applied to the wire harness
in order to remove the wire harness from a discarded vehicle
to recover it, without canceling the retained condition by
pulling the lever piece 15 up with the hand, the wire harness
11 is cut off, and fails to be recovered. And besides, the
retained condition is canceled by pulling the lever piece 15
up by the hand of the operator, and therefore in the case where
there are provided many lever-type connectors, much time and
labor are required for the recovery, and therefore there is
encountered problems that the efficiency of the operation is
low and that the cost increases.
This invention is made in order to overcome the
difficulties of the above conventional techniques, and an
object of the invention is to provide a lever-type connector
in which a wire harness can be easily removed and recovered
efficiently with a simple structure without the use of any
special member or the like at the time of disassembling a
discarded vehicle, and also to provide a wire harness-mounting
structure and a wire harness-removing method, using this
connector.
In the present invention, the above problems is solved
by adopting the following technical means.
A preferred embodiment of the present invention will now
be described.
A preferred embodiment of a lever-type connector of the
invention is schematically shown in Figs. 7 to 9. Fig. 7 is
a schematic, perspective view showing a wire harness-side
portion of the lever-type connector of the invention. Fig.
8 is a view similar to Fig. 5, but showing the lever-type
connector of the invention. Fig. 9A is a view similar to Fig.
8, but showing the process of a connecting operation, and Fig.
9B is a view similar to Fig. 8, but showing a connected condition.
In these Figures, those elements, similar to those of Figs.
3 to 6, are designated by identical reference numerals,
respectively. In Figs. 8 and 9, the showing of a clamp and
a clamp-mounting hole (described later) is omitted for
convenience' sake.
In the lever-type connector of this embodiment, a
connector portion 12 is mounted on a distal end of a wire harness
11 as in the conventional type. On the other hand, a
connector-connecting portion 14 is formed on an electric
connection box (not shown), and the connector portion 12 can
be received in the interior of this connector-connecting
portion. A lever piece 15A is pivotally mounted on the
connector portion 12 by pin members 16, and cam members 17 are
mounted on the connector portion 12. Cam grooves 18,
corresponding respectively to the cam members 17, are formed
in the lever piece 15A. On the other hand, the electric
connection box is similar in structure to that shown in Figs.
3 to 6, and channel-shaped grooves 19 and channel-shaped
grooves 20 are formed in inner surfaces of the
connector-connecting portion 14, and the grooves 19 guide the
pin members 16, respectively, and are engaged respectively
with the pin members 16 when the connector portion 12 is
connected to the connector-connecting portion, and the grooves
20 guide the cam members 17, respectively, and are engaged
respectively with the cam members 17 when the connector portion
12 is connected to the connector-connecting portion.
Although the above structure is similar to that of the
conventional type of Figs. 4 to 6 except the lever piece 15A,
the lever-type connector of this embodiment much differs in
structure from the conventional type in the following points.
Namely, the clamp-mounting hole 22 is formed in a rear portion
of the lever piece 15A, and wall portions 26, which form a
receiving portion 25 for receiving a wire harness 24 having
the clamp 23 secured thereto, extend from the rear portion 21.
The clamp-mounting hole 22 serves to retain and fix the clamp
23 secured to the wire harness 24. The clamp 23 is fixedly
secured to the wire harness 24 by known fixing means such as
a winding tape or a fastening band.
In the above construction, the clamp 23, secured to the
wire harness 24, is inserted into the mounting hole 22, formed
in the lever piece 15A, and is retained and fixed relative
thereto. As a result, the wire harness 24 is fixedly secured
to the lever piece 15A. In this condition, that portion of
the wire harness 24, to which the clamp 23 is secured, is
received in the receiving portion 25, and is prevented by the
wall portions 26 from lateral movement.
The subsequent connecting operation is similar to that
shown in Figs. 3 to 6, and the connector portion 12, connected
to the distal end of the wire harness 11, is inserted into the
connector-connecting portion 14, with the lever piece 15A held
in a released condition (in an upper position), as shown in
Fig. 8. At the time of insertion of the connector portion 12,
the pin members 16 are fitted respectively into the grooves
19 in such a manner that the cam members 17 move along the
grooves 20, respectively. When the connector portion 12 is
inserted to a certain degree, each pin member 16 reaches a
lowermost portion of the corresponding groove 19 (Fig. 9A),
and thereafter the lever piece 15A is pivotally moved right
about the pin members 16 each held in this lowermost portion,
and therefore each cam member 17 moves in accordance with the
configuration of the cam groove 18. Finally, the lever piece
15A is brought into a recumbent condition as shown in Fig. 9B,
and the connected condition is achieved, thus completing the
connection of the connector portion 12 to the
connector-connecting portion 14.
In the above construction, for disconnecting the
connector portion 12 from the connector-connecting portion 14,
a pulling force is applied to the wire harnesses 11 and 24
through a J-shaped hook (not shown) of a lifting machine such
as a crane, thereby pulling the wire harnesses up. At this
time, when the pulling force is applied in a direction of arrow
P (Fig. 7) , this pulling force is transmitted to the lever piece
15A through the wire harness 24, so that the lever piece 15A
is operated or moved from its recumbent condition into its
lifted condition. As a result, the connected condition of the
lever-type connector is automatically canceled. By further
applying the pulling force, not only the wire harness 11 but
also the wire harness 24 can be removed and recovered without
being cut off at their intermediate portion. And besides, the
connection and disconnection of the connector can be easily
effected with the simple structure without the use of any
special part or the like, and the wire harnesses can be
efficiently removed and recovered.
Although one preferred embodiment of the present
invention is described above in detail, the invention is not
limited to the above embodiment, but various modifications and
changes can be made.
For example, in the above embodiment, the wire harness
24 is fixedly secured to the lever piece 15A by the retaining
engagement of the clamp 23 (mounted on the wire harness 24)
in the mounting hole 22 formed in the lever piece 15A, as shown
in Fig. 10. However, the fixing of the wire harness 24 to the
lever piece may be effected by withdrawal prevention members
27 formed respectively on the inner surfaces of the wall
portions 26, as shown in Fig. 11. In another modification,
the wall portions, forming the receiving portion 25, may be
deformed into such a configuration as to fix the wire harness
in a gripping manner. In a further modification, any suitable
fixing member for fixing the wire harness 24 may be provided
at the rear portion of the lever piece.
In the above embodiment, although the cam members 17 and
the cam grooves 18, which jointly form the cam mechanism, are
provided at the lever piece (15A) side, there may be adopted
a construction in which the cam members are provided at the
lever piece side while the cam grooves are provided at the
connector-connecting portion of the electric connection box,
or there may be adopted the reverse combination thereof.
In the present invention, the first and second wire
harnesses, fixedly secured respectively to the connector
portion and the lever piece, may be separate from each other,
or may be two wire harnesses branching off from one wire
harness.
The lever piece and the connector-connecting portion of
the electric connection box are not limited to the respective
illustrated configurations, but can be changed into desired
configurations, respectively.
The lever-type connector of the present invention is
described in the foregoing, and according to the present
invention, there is provided the wire harness-mounting
structure, using this lever-type connector. For the reasons
described above, this mounting structure has advantages that
the recovery of the wire harnesses can be effected easily and
that the mounting of the wire harnesses is easy.
Further, according to the present invention, there is
provided the method in which the pulling force of the hook of
the lifting machine is caused to act on the second wire harness
in the wire harness-mounting structure, and by doing so, the
lever piece of the lever-type connector is automatically
operated so as to effect the removal of the first wire harness,
and also the removal of the second wire harness is effected.
Therefore, advantageously, the wire harness-removing
operation is easy, and the recovery cost can be reduced, and
besides the recovery rate can be increased.
As described above in detail, in the present invention,
the above construction and method are adopted, and therefore
the wire harnesses can be smoothly removed and recovered
without being cut at their intermediate portion at the time
of disassembling a discarded vehicle. Therefore, the
efficiency of the wire harness-removing operation is enhanced,
and the recovery cost is reduced, and besides the recovery rate
is increased.
