DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring structure using a wire harness protector used for electrical connection between electric units.

[0002]

2. Description of the Related Art Generally, a connector is used for electrical connection between electrical units (for example, electrical connection between a dashboard of a vehicle and an instrument panel). For example, when there are a first unit and a second unit to be interconnected, the first unit is provided with the first connector, and the second unit is provided with the second connector. The electrical connection between the two units is made.

Conventionally, as means for connecting the above-mentioned connectors, a wire harness is routed to a first unit and a first connector connected to a terminal of an electric wire of the wire harness is fixed. The wiring harness is also routed to the unit 2
The first connector is not fixed, but is hung from the second unit. First, the two units are connected to each other, and then the second connector is connected to the first connector.

[0004]

The above-mentioned wire harness is accommodated in a wire harness protector having a shape corresponding to the wiring shape of the wire harness, if necessary, and is protected by the protector. In the region from the end to the second connector, the electric wire is exposed from the protector, so that there is a disadvantage that the electric wire is not effectively protected in this region. Moreover,
At the stage before the second unit is connected to the first unit, the second connector is suspended from the second unit via the electric wire, so depending on the assembly line and the mounting position of the connector, There is a possibility that an object may be hooked on the electric wire, and in this case, an excessive tension acts on the electric wire, which may cause a trouble such as disconnection or disconnection of a terminal. Also, at the stage when the connection between the units has been completed, the second connector is located far away from the first connector while still hanging down,
A troublesome operation such as searching for the second connector and then connecting the second connector to the first connector is required, and the efficiency of assembly is low.

The present invention has been made in view of the above circumstances, and provides a wire harness protector and a connector having a simple structure that can effectively protect a connector and wires of a wire harness connected to the connector and facilitate connection between connectors. It is an object to provide a wiring structure using the protector.

[0006]

Means for Solving the Problems As means for solving the above problems, the present invention is directed to a second connector in which a first connector is fixed to a first unit and is connected to the first unit.
A second connector connected to the first connector is provided on the unit side, and a wire harness is provided on the second connector.
In the wiring structure Ness is connected, to the second unit side, and the protector body for protecting this surrounds the Tei Ru wire harness is connected to the second connector, the connector for retaining the second connector Provide a wire harness protector integrally formed with the holder,
This is connected to a wire harness protector of the protector body to the second connector by wiring the wire harness Ru Tei, and the second connector and the second connector relative to the connector holder to the connector holder relative shift
Together is held in rotatably state, as the first unit and the second connector in a state where the second unit is connected is opposite to the first connector, the first
A fixing position of the first connector in one unit is set , and the first connector and the second connector are paired.
The second connector is connected to the connector holder
Relative to the second connector,
It is configured to be connected to the first connector .

According to this structure, the single wire harness protector can integrally protect the wire harness and the second connector connected to the electric wire, and at the same time,
The second connector provided with the protector can hold the second connector, and can move the second connector to connect to the first connector of the other party.

More specifically, the second connector is held by the connector holder at a position separated from the first connector immediately after the first unit and the second unit are connected. At this position, the second connector can be moved and connected to the first connector.

The wire harness protector may be formed integrally with the second unit. However, the wire harness protector and the second unit are separated from each other, and the connector holder is connected to the second connector. And the entire wire harness protector can be attached to the second unit in a state where the wire harness is routed in the protector main body. Wiring and assembling work are easier than directly wiring the wiring harness and attaching the second connector.

As a concrete means for connecting both connectors after connecting both units, the above-mentioned first means is used.
A screw member is fixed to one of the connector and the second connector, and a screw member having a rotation operation portion that can be screwed with the screw member and that is rotated from the outside is rotatable and axially fixed to the other. The first connector and the second unit are attached so that the screw member of the second connector and the screw member of the first connector face each other in a state where the first unit and the second unit are connected. It is preferable that the positions of the screw members are set, and the housings of both connectors are fitted by screwing the screw members together with the relative movement of the second connector with respect to the connector holder. According to this structure, the second connector is moved by, for example, pressing a rotation operation portion of a screw member provided on the second connector, and the second connector side screw member is rotated to operate the second connector. By fitting the housings of the two connectors together while screwing with the screw member on the side of the first connector, the two connectors can be reliably connected to each other.

A connector fastener for fastening the housings of the two connectors in a state where the two units are connected to each other is provided. With the fastening of the connector fastener, the housing of the second connector is moved relative to the connector holder. According to the structure configured to be fitted to the housing of the first connector while relatively moving, after the unit connection is completed,
When the fastening operation of the housings of the two connectors is started with the connector fastener, the second connector is automatically moved relative to the connector holder by the fastening force.
Of the first connector is fitted to the housing of the first connector.

Meters 13 and 14 are mounted on the front side of the instrument panel 12, while a wire harness protector WP according to the present invention is provided on the back side. This wire harness protector WP is
A protector body 18 which is integrally formed of a synthetic resin and has a shape equivalent to the wiring shape of the wire harness (a shape extending in the left-right direction in the illustrated example), and connector holders 20 located at both ends of the protector body 18. Are integrally provided. A wire harness is routed inside the protector body 18 along the protector body 18, thereby protecting the wire harness and being connected to both ends of the wires 16 (FIGS. 2 to 6) of the wire harness. The second connector C2 is temporarily held by the connector holder 20.

On the other hand, a wire harness (not shown) is also routed on the side surface of the dash panel 10, and a first connector C1 (a pair of left and right first connectors C1 in the illustrated example) is connected to a wire terminal of the wire harness. The first connectors C1 are fixed to the dash panel 10 at positions corresponding to the second connectors C2. Then, the first connector C1 and the second connector C2
With this connection, the wire harness on the dash panel 10 and the wire harness on the instrument panel 12 are electrically connected.

The connector holder 20 has a rectangular opening on the inside thereof, and a plurality of guide projections 22 projecting toward the center at a plurality of right and left portions of an entrance portion of the opening. Each of the guide projections 22 is formed with a tapered surface 22a that expands toward the dash panel 10 (toward the dash panel 10). This connector holder 2
A holding elastic member 24 formed in a hollow shape by an elastic material such as rubber is fixed to the back side of the 0, and a locking concave portion 24a is formed at the back of each holding elastic member 24. A through hole 2 is formed in the back wall (right side wall in FIGS. 3 to 6) of the connector holder 20.
5 is formed, and a through hole (not shown) connected to the through hole 25 is also formed in the instrument panel 12.

In this embodiment, the second connector C2
Is a male housing, and a substantially cylindrical nut 26 is rotatably held at the center of the housing. The nut 26 is in a state where its axial movement is restricted by a retaining ring 28.

The nut 26 is connected to the second connector C
It is not necessary for the nuts 26 to be completely immovable in the axial direction. It is only necessary that the movement is regulated,
The nut 26 may be slightly movable relative to the second connector C2 in the axial direction.

At the center of the nut 26, there is formed a screw hole 30 opening toward the first connector C1.
A tapered surface 31 whose diameter increases toward the opening end (toward the left in FIGS. 3 to 6) is formed at the periphery of the opening of the screw hole 30. At the rear end of the nut 26, a flange portion 32 and a rotation operation portion 29 are formed, and the rotation operation portion 29 is formed in an irregular cross-sectional shape so that it can be rotated by an impact wrench (not shown) or the like.

At the rear end (right end in FIGS. 3 to 6) of the housing of the second connector C2, a locked projection 23 is formed on the side. The second connector C2 is temporarily held by the connector holder 20 by being fitted into the locking recess 24a. A guided projection 33 is provided on the side surface of the front end of the housing of the second connector C2 so as to protrude laterally.
The second connector C2 is guided straight in the direction toward the first connector C1 by contacting the inner end surface of the second connector C1.

On the other hand, the first connector C1 is completely fixed to the dash panel 10 by bolts or the like, and the fixed position is between the dash panel 10 and the instrument panel 12 mounted thereon. It is set at a position facing the second connector C2 with a predetermined separation dimension d1.

The housing of the first connector C1 is
A female housing having a housing fitting recess 34 in the center is provided. By fitting the housing of the second connector C2 into the housing fitting recess 34, connector terminals (not shown) of both connectors C1 and C2 are connected to each other. It is to be connected.

At the entrance of the housing fitting concave portion 34, as it approaches the second connector C2 (FIGS.
The tapered surface 38 which expands toward the right in FIG. 6)
Are formed. In the housing of the first connector C1, a bolt 39 that can be screwed and inserted into the screw hole 30 is fixed at a position corresponding to the screw hole 30 of the nut 26 held by the second connector C2. The tip of the bolt 39 is formed with a tapered surface 39a whose diameter decreases toward the tip.

Here, the distance d1 is determined by the tapered surface 39a of the bolt 34 and the nut 2 at the position where the guide of the second connector C2 by the guide protrusion 22 is finished as shown in FIG.
The size is set so that the tapered surface 31 of the No. 6 approaches.

A guide groove for guiding the guided projection 33 in the fitting direction when the connector housing of the second connector C2 is fitted into the housing fitting recess 34 of the first connector C1. 40 are formed.

Next, the wiring procedure in this structure will be described.

First, a wire harness protector WP
A wire harness on the instrument panel 12 side is routed along the protector main body 18 in the protector main body 18, and the second connector C2 connected to the end of the electric wire 16 of the wire harness is connected to the connector holder 20. Is temporarily held. Specifically, the second connector C2
The locking projection 23 of the holding elastic material 24 is
a. Then, in this state, the entire wire harness protector WP is fixed to a predetermined position on the back surface of the instrument panel 12 with bolts or the like. As a result, the arrangement of the wire harness on the instrument panel 12 side and the temporary holding of the second connector are simultaneously performed.

On the other hand, on the dash panel 10 side,
A wire harness is routed on the side surface of the dash panel 10, and the first connector C1 connected to the wire terminal of the wire harness is located at a position corresponding to the second connector C2 on the left and right wing portions of the dash panel 10. Fixed to.

Next, an unillustrated bolt insertion hole of the instrument panel 12 is aligned with an unillustrated screw hole of the dash panel 10, and an unillustrated mounting bolt is screwed into the screw hole through the bolt insertion hole. By inserting, instrument panel 12 is fixed to dash panel 10. At this stage, the housing of the second connector C2 temporarily held by the connector holder 20 faces the housing of the first connector C1, as shown in FIG. There is a gap and the housings have not yet contacted each other. Therefore, breakage due to contact between the two housings is reliably avoided.

In this state, the rotation operating portion 29 is pressed by using a tool or the like, and the engagement between the locked projection 23 and the locking recess 24a is forcibly released (that is, the temporary holding is released. 2.) Push out the second connector C2 toward the first connector C1.

Here, as shown in FIG. 4, until the tapered surface 31 of the nut 26 comes in contact with the tapered surface 39a of the bolt 39, the guided projection 33 contacts the guiding projection 22 and the second projection is formed. Since the connector C2 is guided in the direction toward the first connector C1, the position of the second connector C2 is largely shifted left and right when the temporary holding is released, so that the bolt 39 cannot be inserted into the screw hole 30. Is prevented. In other words, the guide projection 22 causes the bolt 3
The second connector C2 is reliably guided to a position where the tip of the screw 9 enters the screw hole 30 of the nut 26.

By rotating the nut 26 with a tool from the state shown in FIG. 4, the screwing between the bolt 39 and the nut 26 proceeds as shown in FIG. As a result, the housing 40 of the second connector C2 is gradually fitted into the housing fitting recess 34 of the first connector C1, and finally the connection between the two connectors C1 and C2 is completed as shown in FIG. .

According to such a structure, the following effects can be obtained.

Since the second connector C 2 is temporarily held in the connector holder 20, the instrument panel 12 is connected via the wire 16 of the wire harness as in the related art.
Unlike the case where the second connector C2 is hung below the second connector, the second connector C2 and the electric wire 16 connected thereto can be reliably prevented from being damaged.

The temporary holding position of the second connector C 2 by the connector holder 20 is set to the first position when the instrument panel 12 is mounted on the dash panel 10.
Since the connector C1 faces the connector C1, the second connector C2 can be easily coupled to the first connector C1 after the instrument panel 12 is mounted.

Since the connector holder 20 is integrally formed with the protector body 18 for protecting the wire harness, the wire harness can be protected and the second connector C 2 can be formed with a simple structure without increasing the number of parts. Both temporary holding can be performed. Further, since the connector holder 20 and the protector main body 18 are continuous, unlike the case where both are separated, the electric wire 16 can be surely protected also in a region near the second connector C2.

If the wire harness is fitted in the protector body 18 in advance, and the second connector C2 connected to the wire harness is set in the connector holder 20, the entire wire harness protector WP is then installed. By simply attaching the wire harness to the instrument panel 12 and attaching the second connector C2 only by attaching the instrument to the instrument panel 12, the assembly workability is significantly improved.

A second embodiment will be described with reference to FIGS. 7 (a) and 7 (b).

The connector holder 20 shown here also has a rectangular opening inside, and the entrance portion of this opening has a tapered surface that expands toward the dashboard 10 (to the left in FIG. 7). 52, a pair of upper and lower temporary locking ridges 54 extending in the width direction are formed at the back.

The housing of the second connector C2 is a male housing, and has a plurality (four in the example) of terminal connection portions 56 projecting forward from the front surface (left surface in FIG. 7). A terminal (not shown) is fixed to the connection portion 56. The left and right wings of the housing are provided with bolt insertion holes 58 penetrating the housing in the front-back direction, and upper and lower portions of the housing are formed with a flexure piece 60 extending rearward from a front end thereof. A locked projection 62 protruding outward is formed at the rear end of 60. And
The second connector C2 is inserted into the inside of the connector holder 20 from the side of the locked projection 62, and the
The second connector C2 is temporarily locked to the connector holder 20 by pushing the second connector C2 to a position over the temporary locking ridge 54.

A through-hole 25 for passing wiring is formed in a region of the connector holder 20 including all the terminal connection portions 56 and the bolt insertion holes 58, and matches the through-hole 25 in the instrument panel 12. A through hole having the same shape is also provided at the position.

On the other hand, the first connector C1 is completely fixed to the dashboard 10 by bolts or the like, and the fixing position is the second connector C1 with the instrument panel 12 attached to the dashboard 10. The connector C2 is set at a position facing the connector C2. This first
The housing of the connector C1 is a female housing having a housing fitting recess 34 at the center, and the housing of the second connector C2 can be fitted into the housing fitting recess 34. On the bottom surface of the housing fitting concave portion 34, a terminal connecting concave portion 66 is formed at a position corresponding to each of the terminal connecting portions 56, and a terminal (not shown) is fixed to the bottom surface of the terminal connecting concave portion 66. The terminals of both connectors C1 and C2 are connected to each other by fitting the terminal connection portion 56 into the terminal connection recess 66.

A tapered surface 38 is formed at the entrance of the housing fitting recess 34 so as to expand toward the second connector C2 (to the right in the figure). In the housing of the first connector C1, screw holes 64 smaller in diameter than the bolt insertion holes 58 are formed at positions corresponding to the two bolt insertion holes 58 of the second connector C2. Then, with the instrument panel 12 attached to the dashboard 10, as shown in FIG.
The dashboard 10 and the instrument are arranged such that the housings 2 are separated from each other with a small gap and the screw holes 64 are completely included in the bolt insertion holes 58 when viewed from the through holes 25 of the instrument panel 12. The mounting positions of the connectors C1 and C2 with respect to the ment panel 12 are set.

Further, in this structure, both connectors C1,
A fastening bolt 43 is provided as a connector fastener for fastening C2. One end of the fastening bolt 43 is a male screw part 41, and the other end is a head having a flange part (large diameter part) 42. Male screw part 41
Is configured to be screwably inserted into the screw hole 64 of the first connector C1, the diameter of the flange portion 42 is larger than the hole diameter of the bolt insertion hole 58 of the second connector C2, and It is set smaller than the hole diameter of the through hole 25 in the mental panel 12.

According to this structure, after the dash panel 10 and the instrument panel 12 are connected as in the first embodiment, both connectors C are connected as follows.
1, C2 are combined.

First, in the state after the above connection, the housing of the second connector C2 is separated from the housing of the first connector C1 and has not yet contacted. Therefore, breakage due to contact between the two housings is reliably avoided.

Here, since the bolt insertion hole 58 of the second connector C2 is sufficiently larger than the screw hole 64, the center axis of both connectors C1 and C2 (in FIG. Even if the position indicated by the one-dot chain line is slightly displaced, a state where the male screw portion 41 of the fastening bolt 43 can be screwed into the screw hole 64 through the bolt insertion hole 58 is ensured. Then, the above screwing and insertion are actually performed, and the fastening of both connectors C1 and C2 by the fastening bolt 43 is started.

In this fastening, the flange 42 of the fastening bolt 43 is actually inserted into the bolt insertion hole 58 of the second connector C2.
The second connector C2 is pulled into the first connector C1 side by this fastening force, and the locked projection 62 of the second connector C2 is temporarily engaged with the connector holder 20 by the fastening force. The second connector C <b> 2 is separated from the connector holder 20 over the stop protrusion 54. And
While the housing of the second connector C2 is fitted into the housing fitting recess 34 of the first connector C1 while being guided by the tapered surface 38, the terminal connecting portion 56 is finally fitted into the terminal connecting recess 66. And both connectors C
The connection between C1 and C2 is completed (the state shown in FIG. 7B).

Therefore, in this structure, the dashboard 1
When the instrument panel 12 is connected to the instrument panel 12, the housings of the connectors C1 and C2 can be reliably protected, and the dashboard 10 and the instrument panel 1 are connected.
After the connection with the connector C2 is completed, the connectors C1 and C2 are connected by a simple operation of merely screwing and inserting the fastening bolt 43 into the screw hole 64.
C2 can be reliably connected to each other.
