Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connector bracket, and more particularly to a connector bracket that can easily route a wire harness having a large bending rigidity and a wire harness having a small bending rigidity in an area where space is limited, such as a vehicle.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, wiring of a wire harness in a vehicle or the like has been performed by attaching a connector housing connected to various devices to a connector bracket fixed to a mounting portion of a vehicle body or the like.
Thereby, various connectors are centrally arranged, and maintenance and the like are facilitated.
[0003]
A wire harness is led out of the connector housing mounted on the connector bracket, and is bent at a substantially right angle on the back side of the connector bracket and routed. Hereinafter, in this specification, the side from which the wire harness is led out from the connector bracket is defined as the back side, and the side to which the connector is attached and detached is defined as the front side.
[0004]
This is because the other side of the connector bracket is often provided with other equipment or a partition wall of the vehicle body, and the distance in the direction of detaching the connector is short. This is because it is difficult to route the harness while keeping it straight.
[0005]
The conventional connector bracket has a flat surface (back surface) on the side from which the wire harness is led out.
Therefore, the wiring harness wiring space provided on the back surface of the connector bracket is a fixed space (distance) regardless of the type of the wire harness.
[0006]
[Problems to be solved by the invention]
In recent years, devices mounted on vehicles have been diversified, and devices that require high current have also been increasingly mounted. Along with this, wiring of a high-current wire harness is required, but usually, the high-current wire harness tends to have a large diameter and a high bending rigidity.
[0007]
When the connector housing to which the high-current wire harness is connected is attached to a conventional connector bracket, the high-current wire harness is forcibly bent at a substantially right angle in the narrow space behind the connector bracket and arranged. .
If a high-current wire harness with high bending rigidity is bent with a small radius of curvature, excessive force will act on the connector housing and connector bracket mounting parts, and the connector housing will be attached in a bent state, causing the connector to be attached and detached. There were cases,
In an extreme case, there is a problem that the mounting portion of the connector bracket is damaged.
[0008]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a connector bracket to which a wire harness having high bending rigidity can be easily attached.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a connector bracket in which a connector housing in which a connection terminal fixed to a tip of an electric wire is inserted and mounted is provided, and a high-rigidity wire harness having a large bending rigidity is provided. A high rigidity wire harness arrangement area to be arranged and a low rigidity wire harness arrangement area to arrange a low rigidity wire harness having a small bending rigidity are separately arranged, and a step is provided on a side from which the wire harness is led out. The derivable length of the wire harness is set so that the high-rigidity wire harness arrangement area is longer than the low-rigidity wire harness arrangement area, and the high-rigidity wire harness is smaller than the radius of curvature of the low-rigidity wire harness. It is characterized by being able to be routed by bending at a large radius of curvature.
[0010]
In the connector bracket configured as described above, a high-rigidity wire harness arrangement area where a high-rigidity wire harness having a large bending rigidity is arranged, and a low-rigidity wire harness arrangement area where a low-rigidity wire harness having a small bending rigidity is arranged. Are arranged separately, so that the high-current wire harness and the low-current wire harness can be concentrated and arranged at one place.
[0011]
In addition, on the back side of the connector bracket, a step is provided in the high-rigidity wire harness arrangement area and the low-rigidity wiring harness arrangement area, and the length of the high-rigidity wire harness arrangement area where the wire harness can be led out is increased. It is possible to bend and route with a large radius of curvature.
[0012]
In this connector bracket, it is possible to solve the problem that wiring cannot be performed unless the wire harness is bent at a constant radius of curvature regardless of the rigidity of the wire harness as in the conventional case.
[0013]
Therefore, depending on the bending rigidity of the wire harness, the high-rigidity wire harness should be bent with a large radius of curvature, and the low-rigidity wire harness should be bent with a small radius of curvature, and the wires should be routed without forcibly bending the wire harness. Can be.
As a result, the conventional problem that a large force acts on the mounting portion of the connector housing and the connector bracket to bend and attach the connector housing or, in an extreme case, damage the mounting portion of the connector bracket can be solved.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a connector bracket according to the present invention, and FIG. 2 is a plan view showing a state of a wire harness mounted on the connector bracket and bent at a substantially right angle and routed.

As shown in FIG. 1, a connector bracket 1 according to an embodiment of the present invention is manufactured by dividing a high-rigidity wire harness arrangement area 2 and a low-rigidity wire harness arrangement area 3 and integrally molding the same with a synthetic resin. I have.
A step H is provided between the high-rigidity wire harness arrangement area 2 and the low-rigidity wire harness arrangement area 3 on the back side 1A of the connector bracket 1 in the wire harness lead-out direction.
[0016]
Specifically, a step H is formed between the back surface 3 a of the low-rigidity wire harness arrangement region 3 and the back surface 2 a of the high-rigidity wire harness arrangement region 2.
As shown in FIG. 2, the low-rigidity wire harness arrangement area 3 is fixed by bringing the back surface 3 a into contact with the mounting portion 4. At this time, the back surface 2 a of the high-rigidity wire harness arrangement area 2 is It is arranged to be separated from the mounting portion 4 by the step H.
[0017]
As shown in FIG. 1, the high-rigidity wire harness arrangement area 2 is for mounting and arranging a connector housing 6 to which a high-rigidity wire harness 5 having a large bending rigidity such as a wire harness having a large current capacity is connected. It is formed in a square pipe shape having a substantially rectangular wall 2b on the outer periphery.
The inside of the square pipe is partitioned by a rib 2c, and a locking mechanism 2d for fixing the connector housing 6 is provided. Then, the connector housing 6 is inserted into the square pipe, engaged with the locking mechanism 2d, and mounted and fixed.
[0018]
The low-rigidity wire harness arrangement area 3 is for mounting and arranging a connector housing 9 to which a low-rigidity wire harness 8 having a small bending rigidity such as a wire harness having a relatively small current capacity is connected. Like the high-rigidity wire harness arrangement area 2, it is formed into a square pipe shape having a substantially rectangular wall 3b provided on the outer periphery.
The inside of the square pipe is partitioned by a rib 3c, and a locking mechanism 3d for fixing the connector housing 9 is provided.
[0019]
One side surface of the wall 2b of the high-rigidity wire harness arrangement area 2 extends in the wire harness lead-out direction to form a connecting portion 2e. One side surface of the wall 3b is formed continuously with the connecting portion 2e, and a step H is provided between the back surface 3a of the low-rigidity wire harness arrangement region 3 and the back surface 2a of the high-rigidity wire harness arrangement region 2. Have been.
Then, the connector housing 9 is inserted into the square pipe, engaged with the locking mechanism 3d, and mounted and fixed.
[0020]
As shown in FIG. 2, from the connector housing 6 mounted on the connector bracket 1, a high-rigidity wire harness 5 is led out rearward, is bent at a substantially right angle with a large radius of curvature R1, and is disposed in each part of the vehicle. For example, it is connected to a device that operates with a large current.
Similarly, from the connector housing 9, a low-rigidity wire harness 8 is drawn out rearward, bent at a substantially right angle with a small radius of curvature R2, and is disposed in each part of the vehicle, for example, for a device that operates with a relatively small current. It is connected.
[0021]
Although the connector bracket 1 shown in the figure has been described as having a step formed not only on the back side but also on the front side, the surface side of the high-rigidity wire harness arrangement area 2 and the low-rigidity wire harness arrangement area 3 are flush with each other. May be formed.
In this case, all the connector housings 6 and 9 can be arranged on the same surface, and there is an advantage that the attachment and detachment of the connector are easy.
[0022]

Can be done, and no unreasonable force will be generated.
[0023]
If the low-rigidity wire harness 8 is erroneously arranged in the high-rigidity wire harness arrangement area 2, a large space remains on the back side 1A of the connector bracket 1. Conversely, when the high-rigidity wire harness 5 is disposed in the low-rigidity wire harness arrangement area 3, it becomes difficult to bend the high-rigidity wire harness 5 in a narrow space.
Therefore, erroneous assembling can be easily detected while assembling the wire harnesses 5, 8, and erroneous wiring can be reliably prevented.

The form, number, location, etc. are arbitrary and not limited as long as the present invention can be achieved.
[0026]
【The invention's effect】
As described above, according to the present invention, the high-rigidity wire harness arrangement area for disposing the high-rigidity wire harness and the low-rigidity wire harness arrangement area for disposing the low-rigidity wire harness are arranged separately. The high-current wire harness and the low-current wire harness can be centrally arranged at one location, so that maintenance and the like can be easily performed.
In addition, a step is provided between the high-rigidity wire harness arrangement area and the low-rigidity wire harness arrangement area on the back surface of the connector bracket to increase the length of the wire harness that can be led out of the high-rigidity wire harness arrangement area. The rigid wire harness can be routed with a large radius of curvature.
[0027]
Therefore, the problem that the wire harness must be bent at a constant radius of curvature regardless of the rigidity of the wire harness as in the related art can be solved. Also, depending on the bending stiffness of the wire harness, the high-rigidity wire harness can be bent with a large radius of curvature, and the low-rigidity wire harness can be bent with a small radius of curvature. can do. As a result, a large force does not act on the mounting portion of the connector housing and the connector bracket, so that the connector housing can be bent and mounted, and the mounting portion of the connector bracket can be prevented from being damaged.
Further, from the bent state of the wire harness on the back side of the connector bracket, erroneous assembly of the high-rigidity wire harness and the low-rigidity wire harness can be easily detected, and erroneous assembly can be prevented.
