Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector used for bending and wiring an electric wire drawn rearward.

[0002]

2. Description of the Related Art For example, a wire harness for an automobile is arranged in a narrow installation space of a vehicle body in a complicated three-dimensional posture. Therefore, a connector provided in the wire harness has an electric wire drawn rearward. Immediately after it is drawn out, it is often bent and wired under severe bending conditions such as right-angled bending. Therefore, the following two methods are adopted as a measure for bending an electric wire drawn from a connector into a required bending posture.

That is, refer to FIG. 3, one of which is the connector 1
The electric wire 3 pulled out from the
0, and a manual bending method to fix the bending posture,
The other one uses a wiring member 11 which is a separate groove body that is fitted to the rear end of the connector 1 and has a required bending posture. The electric wire 3 is put in the groove of the wiring member 11 and the tape winding 10 It is a method of applying and setting.

[0004]

Among the above-mentioned conventional techniques, the former manual bending naturally causes "variation" of the bending posture due to manual work, and the bending posture may be collapsed due to imperfect tape winding. In a wire harness for an automobile arranged in a narrow permissible space, the lead-out electric wire 3 comes into contact with a peripheral device and relatively interferes with the vibration of a vehicle body or the like, which causes a problem in that the wire harness or the device is damaged.

On the other hand, when the latter wiring member 11 is used, since the wiring member 11 is fitted to the rear end of the connector 1 and the fitting and locking force holds the bending posture of the wire 3. A wiring member 11 having a fitting portion shape that is individually matched with the connectors 1 having various shapes is required. Therefore, it is necessary to prepare an extremely large number of wiring members 11 in which various shapes of fitting portions and various bending shapes are combined, which makes the management of the parts complicated and increases the cost. The present invention is
It is intended to provide a connector which solves the above-mentioned drawbacks of the prior art.

SUMMARY OF THE INVENTION The connector of the present invention for solving the above technical problem is "a regulating plate locking portion for detachably locking the front end portion of the wiring regulating plate on the side circumference of the wire drawing side. A wiring that forms a connector body having the connector body and a plate body having a required bending shape, inserts the first half locking portion into the regulation plate locking portion, and makes the latter half regulation portion in a protruding posture from the connector body. `` Connecting and combining structure with the restriction plate '', and set the wire to the required bend by laying the lead wire from the connector body along the tape with the restricting part of the wire restricting plate in that combined and combined posture and winding the tape together. It is supposed to do. Then, as a mode thereof, either one of the front and back surfaces of the locking portion of the wiring regulation plate is selected, and a locking mechanism capable of being inserted and locked in the regulation plate locking portion of the connector body is adopted.

[0007]

In the connector of the present invention having the above construction, the electric wire is set along the wiring regulation plate by tape winding, so that the bending posture of the electric wire exhibits a bending posture conforming to the wiring regulation plate. Becomes uniform. By standardizing the shape of the restriction plate locking part of the connector body, various bending shapes having a common locking part can be interchangeably combined. It suffices to prepare only the points having different shapes, and the number of parts can be significantly reduced as compared with the conventional wiring member described above. Further, the locking plate of the above aspect capable of being selectively locked on both sides can be commonly used for, for example, right-bending wiring and left-bending wiring of an electric wire depending on the selection.

[0008]

Embodiments will be described in detail below based on embodiments. With reference to FIG. 1 showing an embodiment of the present invention, in a connector for an automobile wire harness, in which a terminal is inserted and an electric wire 3 is drawn out rearward, and the electric wire 3 is bent at a right angle immediately after being drawn out for wiring. This connector is provided on the side circumference of a connector body 1 in which the respective terminals are inserted in the terminal accommodating chamber, the electric wire 3 is drawn out backward, and the front half portion is connected to the mating side, and the rear end portion of the connector body 1. The wiring regulation plate 2 having a bent shape that matches the bending wiring posture of the electric wire 3 is inserted and locked in the regulation plate locking portion 4 and protrudes rearward of the connector body 1 to be mounted and coupled. It has a combined structure with the plate 2.

More specifically, in the wiring regulation plate 2, the rectangular locking portion 5 is used as the first half portion, and the regulation portion 6 in the latter half portion is formed as a single plate body having a required bending shape. The connector 5 is detachably inserted and coupled to the restriction plate locking portion 4 of the connector body 1. The regulation plate locking portion 4 is composed of a pair of locking ridges 7 provided upright on the side circumference of the connector body 1, and the locking portion 5 is received and inserted between the locking ridges 7 to form the regulation plate engaging portion. The locking projection 8 at the center of the stopper 4 and the locking hole 9 on the side of the locking portion 5 are engaged and locked, and both are combined and combined.

Then, the electric wire regulation plate 2 is inserted and locked in the connector body 1 into which the terminal is inserted and the electric wire 3 is drawn out rearward, and the regulation portion 6 is bent and protrudes rearward.
Then, the electric wire 3 is bent into a bent posture, and the tape winding 10 is applied from above to fix the restriction portion 6 and the electric wire 3 together, and the connector body 1 is connected to the mating side to perform the bent wiring. It The above-mentioned embodiment has the above-mentioned action, and if the regulating plate locking portion 4 is standardized between the connector bodies 1 having different numbers of poles and sizes, wiring corresponding to various bending shapes of the electric wire 3 is performed. By selecting and combining the regulation plates 2, it is possible to immediately respond to electric wire bending wiring under various bending conditions, and
Even if the wiring regulation plate 2 is changed to the front side and the back side and inserted into the regulation plate locking portion 4, the locking mechanism of the locking projection 8 and the locking hole 9 of this embodiment functions as it is. Therefore, the single wire regulation plate 2 can be used for both the right bent wiring and the left bent wiring of the electric wire 3.

Therefore, in the wiring regulation plate 2, if only the regulation portion 6 satisfying the above-mentioned bending condition in consideration of the commonality is made different and only the points having the common locking portion 5 are prepared, various wire bending can be performed. Even in the case of a wire harness connector that has conditions, the number of parts is significantly reduced compared to the wiring member 11, the manageability of parts is improved, and the cost can be reduced. Then, the electric wire 3 provided along the regulation portion 6 by the tape winding 10 is less likely to largely break the bending posture regulated by the regulation portion 6 even if the tape is loosened due to the winding failure of the tape winding 10, and thus the basic bending Since the posture is maintained, the possibility of causing contact interference with peripheral devices is extremely low, and the wiring quality of the electric wire 3 can be maintained.

Next, another embodiment of the present invention will be described with reference to FIG. That is, FIG. 2 shows another shape of the wiring restricting plate 2, and the restricting portion 6 is bent in a right-angled upward bend / a right-angled downward bend, or a diagonal upward bend / a diagonal downward bend, etc. with respect to the connector body 1. To be done.

[0013]

As described above, according to the connector of the present invention, when the lead wire is severely bent at a right angle and variously bent and wired, the bent wire performance is stable and the bent wire is used. The number of parts is reduced to improve the manageability of parts and reduce costs.
