Conventionally, an electrical connection box such as a relay box mounted on a vehicle and accommodating an electronic component such as a relay is widely known (see, for example, Patent Document 1). The housing of the electrical junction box is usually provided with an electric wire drawing portion for pulling out the tip end side of the electric wire connected to the electronic component to the outside of the housing. The electric wire lead-out portion is provided with a fixing portion for fixing the electric wire.

Japanese Unexamined Patent Publication No. 2014-171318

As a method of fixing the electric wire in the fixing portion, usually, a first method of fixing the clamp of the binding band with a clamp attached to the electric wire to the clamp fixing portion provided in the fixing portion, and a method provided in the fixing portion. Only one of the second method of attaching the electric wire to the non-clamp binding band in which the band portion is fixed to the band fixing portion is adopted.

In the first method, since it is possible to attach a binding band with a clamp to the electric wire in advance before arranging the electric wire in the fixed portion of the electric wire drawing portion, the desired length from the end on the tip side of the electric wire. It is easy to accurately attach a cable tie with a clamp to the position. Therefore, after the electric wire is attached to the electric junction box (after being fixed to the fixed portion), it is easy to manage the extension length of the electric wire from the electric wire drawing portion to the outside. However, the fixing force of the electric wire to the fixing portion is relatively weak due to the relatively weak fixing force of the clamp to the clamp fixing portion.

In the second method, after arranging the electric wire in the fixed part of the electric wire lead-out part, the electric wire is attached to the unclamped tying band. Difficult to attach to. For this reason, it is difficult to control the extension length of the electric wire from the electric wire lead-out portion to the outside after the electric wire is attached to the electric junction box (after being fixed to the fixed portion). However, due to the relatively strong fixing force of the band portion to the band fixing portion, the fixing force of the electric wire to the fixing portion is relatively strong.

From the above, it has been required that the extension length of the electric wire from the electric wire lead-out portion to the outside can be easily controlled and the fixing force of the electric wire to the fixing portion be strengthened.

The present invention has been made in view of the above circumstances, and an object of the present invention is to easily control the extension length of the electric wire from the electric wire lead-out portion to the outside and to strengthen the fixing force of the electric wire to the fixed portion. It is an object of the present invention to provide an electric junction box that can be used and a method of fixing an electric wire to the electric junction box.

In order to achieve the above-mentioned object, the electric connection box according to the present invention and the method of fixing the electric wire to the electric connection box are characterized by the following [1] to [3].

A housing for accommodating at least one electronic component, and a fixing portion for fixing an electric wire lead-out portion provided in the housing, the base end side of which is connected to the electronic component and the tip end side of which is drawn out of the housing. In an electrical junction box with, and with a wire lead
The fixing portion is a binding band with a clamp attached to the electric wire, and is a binding band with a clamp provided with a clamp for attaching the head portion to another component in a head portion for adjusting the circumferential length of the band portion. The clamp fixing part that fixes the clamp and the head part that is a binding band without clamp attached to the electric wire and adjusts the circumference of the band part are not provided with a clamp for attaching the head part to other parts. A band fixing portion for fixing the band portion in the band is provided.
Must be an electrical junction box.
[2]
In the electrical connection box described in [1] above,
In the fixing portion, the band fixing portion is located closer to the tip end side of the electric wire than the clamp fixing portion.
Must be an electrical junction box.
[3]
The method of fixing the electric wire to the fixing portion of the electrical connection box according to the above [1] or the above [2].
The binding band with the clamp is attached at a position of a predetermined length from the end on the tip side of the electric wire, and then the binding band with the clamp is attached.
The electric wire to which the binding band with the clamp is attached is arranged in the fixing portion to fix the clamp to the clamp fixing portion, and then
The electric wire is attached to the clampless binding band in which the band portion is fixed to the band fixing portion.
The method of fixing the electric wire to the electric junction box.

According to the electrical connection box having the configuration of [1] above, the electric wire can be fixed to the fixing portion by using both the fixing directions of the first and second methods described above. Therefore, since both the advantages of the first method and the advantages of the second method can be enjoyed, it is easy to manage the extension length of the electric wire from the electric wire lead-out portion to the outside, and the electric wire is fixed to the fixed portion. It becomes possible to strengthen the power.

Unlike the electric connection box having the configuration of [2] above, in the fixed portion, in the embodiment in which the binding band with clamp is located closer to the tip of the electric wire than the binding band without clamp, the electric wire extending from the electric wire drawing portion to the outside is used. When an external force acts, the force derived from the external force acts on the binding band with a clamp located on the tip side of the electric wire. In this case, the binding band with the clamp is likely to be separated from the fixed portion due to the relatively weak fixing force of the clamp to the clamp fixing portion. On the other hand, in the fixed portion as in the electric junction box having the configuration of [2] above, in the embodiment in which the binding band without clamp is located closer to the tip of the electric wire than the binding band with clamp, the binding band extends from the electric wire drawing portion to the outside. When an external force acts on the electric wire to be output, a force derived from the external force acts on the clampless binding band located on the tip side of the electric wire. In this case, it is unlikely that the binding band without clamp is separated from the fixed portion due to the relatively strong fixing force of the band portion to the band fixing portion. Therefore, when an external force acts on the electric wire extending from the electric wire drawing portion to the outside, it becomes difficult to separate both the binding band without the clamp and the binding band with the clamp from the fixed portion.

According to the method of fixing the electric wire to the electric junction box having the configuration of the above [3], first, the electric wire is fixed to the fixing portion by using the binding band with the clamp by the first method, and then the first method. By the method of 2, the electric wire is further fixed to the fixing portion by using a binding band without a clamp. Therefore, since both the advantages of the first method and the advantages of the second method can be enjoyed, it is easy to manage the extension length of the electric wire from the electric wire lead-out portion to the outside, and the electric wire is fixed to the fixed portion. It becomes possible to strengthen the power.

As described above, according to the present invention, an electric connection box that can easily control the extension length of the electric wire from the electric wire lead-out portion to the outside and can strengthen the fixing force of the electric wire to the fixed portion, and A method of fixing an electric wire to an electric junction box can be provided.

The present invention has been briefly described above. Further, the details of the present invention will be further clarified by reading through the embodiments for carrying out the invention described below with reference to the accompanying drawings.

<Embodiment>
Hereinafter, the electrical connection box 1 according to the embodiment of the present invention shown in FIGS. 1 and 2 will be described with reference to the drawings. The electrical junction box 1 is typically a relay box mounted on a vehicle and accommodating electronic components such as relays. Hereinafter, for convenience of explanation, "vertical direction", "upper" and "lower" in FIG. 1 are defined as "vertical direction", "upper" and "lower", respectively. When the electric junction box 1 is mounted on the vehicle, the "vertical direction" corresponds to the vertical direction of the vehicle.

As shown in FIGS. 1 and 2, the resin electrical connection box 1 includes a housing 10 that houses a plurality of electronic components 15 (see FIG. 3 and the like). In this example, the housing 10 includes a substantially rectangular frame-shaped frame 11 for accommodating a plurality of electronic components 15, an upper cover 12 assembled above the frame 11 so as to close the upper opening of the frame 11, and the frame 11. It is composed of a lower cover 13 assembled below the frame 11 so as to close the lower opening. The above three parts constituting the electric junction box 1 are all resin molded bodies.

In the electrical junction box 1, as shown in FIGS. 1 and 2, the tip end side of the electric wire 50 whose base end side is connected to the electronic component 15 inside the housing 10 is the electric wire outlet 14 formed in the housing 10. It is pulled out to the outside of the housing 10 via (see FIG. 2). In this example, the electric wire 50 is drawn out from each of the two electric wire outlets 14 formed in the mating portion of the frame 11 and the lower cover 13.

In this example, a part of the inner wall surface of the housing 10 continuous with the electric wire outlet 14 functions as the electric wire extraction portion 20. The electric wire lead-out portion 20 serves a guide function of guiding the electric wire 50 inside the housing 10 and defining the wiring form of the electric wire 50 inside the housing 10. For example, as shown in FIG. 3, the electric wire outlet 14 on the left side of the two electric wire outlets 14 shown in FIG. 2 faces downward, which is a part of the inner wall surface of the frame 11 continuous with the electric wire outlet 14. This portion functions as an electric wire lead-out portion 20.

Specifically, as shown in FIG. 3, the electric wire lead-out portion 20 is located at the lowermost portion 21 located below the electronic component 15 from the vicinity of the electronic component 15 to which the base end portion of the electric wire 50 is connected. It is composed of a first inclined portion 22 that is inclined so as to descend toward the wire, a lowermost portion 21, and a second inclined portion 23 that is inclined so as to ascend from the lowermost portion 21 toward the electric wire outlet 14. The upper end portion (tip portion) of the second inclined portion 23 extends continuously from the electric wire outlet 14 to the outside of the housing 10 and is located outside the housing 10.

The electric wire 50 drawn from the inside to the outside of the housing 10 by the electric wire drawing portion 20 is first guided from a portion near the electronic component 15 to the tip end side by the first inclined portion 22 and at the lowermost portion. It descends toward 21, passes near the lowermost portion 21, rises toward the electric wire outlet 14 while being guided by the second inclined portion 23, and extends from the electric wire outlet 14 to the outside of the housing 10. Put out.

Since the electric wire 50 is arranged along the electric wire lead-out portion 20 in this way, water droplets adhering to the electric wire 50 located outside the housing 10 temporarily descend toward the electric wire outlet 14 due to the action of gravity. Even if it enters the inside of the housing 10 through the electric wire outlet 14 through the electric wire 50, the water droplet is located in the vicinity of the lowermost portion 21 along the electric wire 50 further descending toward the lowermost portion 21. After reaching the bottom of the electric wire 50, it falls downward. That is, the water droplet that has reached the bottom of the electric wire 50 does not reach the electronic component 15 along the electric wire 50 that rises toward the electronic component 15 against gravity. Therefore, even if water droplets enter the inside of the housing 10 through the electric wire 50, the electronic component 15 will not be exposed to water.

Further, since the first inclined portion 22 of the electric wire drawing portion 20 is formed in this way, the height of the inner wall surface of the housing 10 (frame 11) in the vicinity portion of the electronic component 15 is set to be the height of the electronic component 15. It can be almost the same. Therefore, when the block (frame-shaped body) accommodating the electronic component 15 is fitted into the housing 10 (frame 11), the inner wall surface is less likely to be an obstacle, and when the block accommodating the electronic component 15 is fitted. Workability is improved.

In the electric wire lead-out portion 20 shown in FIG. 3, the second inclined portion 23 in the vicinity of the electric wire outlet 14 functions as a fixing portion for fixing the electric wire 50 drawn out from the electric wire outlet 14. Specifically, in this example, as shown in FIG. 3, the second inclined portion 23 has a clamp fixing through hole 24 for fixing the clamp 33 provided in the clamped binding band 30 shown in FIG. And two band insertion holes 25 and 26 for fixing the band portion 41 of the clampless binding band 40 shown in FIG. 5 are provided.

The clamp fixing through hole 24 is located inside the housing 10 with respect to the electric wire outlet 14, and the band insertion holes 25 and 26 are located outside the housing 10 with respect to the electric wire outlet 14. Therefore, the band insertion holes 25 and 26 are located closer to the tip end side of the electric wire 50 than the clamp fixing through hole 24.

As shown in FIG. 4, the binding band 30 with a clamp includes a band portion 31, a head portion 32 fixed to a base end portion of the band portion 31, and a clamp 33 fixed to the head portion 32. As shown in FIG. 4, the annular band portion 31 is formed by inserting the tip portion of the band portion 31 into the insertion hole (not shown) provided in the head portion 32. By adjusting the extending length of the tip of the band portion 31 inserted into the insertion hole from the head portion 32, the peripheral length of the annular band portion 31 can be arbitrarily adjusted.

The clamp 33 is provided for attaching the head portion 32 to other parts. In this example, as shown in FIG. 7, the head portion 32 (hence, the binding band 30 with a clamp) is fixed to the second inclined portion 23 with one touch by inserting the clamp 33 into the through hole 24 for fixing the clamp. be able to.

When the clamp 33 is inserted into the clamp fixing through hole 24 while the binding band 30 with a clamp is maintained in the direction opposite to the direction shown in FIG. 7, a part of the band portion 31 is a housing. The clamp 33 cannot be inserted into the clamp fixing through hole 24 due to interference with the side wall 16 (see FIG. 7) of the 10 (specifically, the frame 11). As a result, it is possible to prevent the binding band 30 with the clamp from being fixed to the second inclined portion 23 in the direction opposite to the direction shown in FIG.

As shown in FIG. 5, the clampless binding band 40 includes a band portion 41 and a head portion 42 fixed to a base end portion of the band portion 41. The binding band 40 without a clamp corresponds to the binding band 30 with a clamp in which the clamp 33 is omitted. As shown in FIG. 5, the annular band portion 41 is formed by inserting the tip portion of the band portion 41 into the insertion hole (not shown) provided in the head portion 42. By adjusting the extending length of the tip of the band portion 41 inserted into the insertion hole from the head portion 42, the peripheral length of the annular band portion 41 can be arbitrarily adjusted.

Hereinafter, a procedure for fixing the electric wire 50 to the second inclined portion 23 of the electric wire drawing portion 20 by using the binding band 30 with a clamp and the binding band 40 without a clamp will be described with reference to FIGS. 6 to 9.

First, the binding band 30 with a clamp is attached to the electric wire 50 in advance before the electric wire 50 is arranged on the second inclined portion 23 of the electric wire lead-out portion 20. Therefore, when the work of attaching the binding band 30 with a clamp to the electric wire 50 is performed, the second inclined portion 23 does not get in the way, so that the binding band 30 with a clamp is located at a position of the desired length from the end on the tip side of the electric wire 50. Easy to install accurately. Therefore, after the electric wire 50 is attached to the electric connection box 1, it is easy to manage the extension length of the electric wire 50 from the electric wire outlet 14 to the outside.

Next, as shown in FIG. 6 (and FIG. 7), the clamp 33 of the binding band 30 with a clamp attached to the electric wire 50 is inserted into the clamp fixing through hole 24 provided in the second inclined portion 23. Then, the binding band 30 with a clamp (hence, the electric wire 50) is fixed to the second inclined portion 23 with one touch (see also FIG. 1; corresponding to the above-mentioned "first method"). Due to the fact that the clamp fixing through hole 24 is located inside the housing 10 with respect to the electric wire outlet 14, the binding band 30 with a clamp is inside the housing 10 with respect to the electric wire outlet 14. It is fixed.

However, since the clamp 33 is fixed to the clamp fixing through hole 24 with one touch, the fixing force of the clamp 33 to the clamp fixing through hole 24 is relatively weak. Therefore, the fixing force of the binding band 30 with a clamp (thus, the electric wire 50) to the second inclined portion 23 is relatively weak.

Next, the band portion 41 of the clampless binding band 40 is inserted into the two band insertion holes 25 and 26 provided in the second inclined portion 23, and the clampless binding band 40 is fixed to the second inclined portion 23. Due to the band insertion holes 25 and 26 located outside the housing 10 with respect to the wire outlet 14, the clampless binding band 40 is located outside the housing 10 with respect to the wire outlet 14. It is fixed (see also Figures 1 and 2).

Specifically, the tip of the band portion 41 is inserted into the band insertion hole 25 from the inner wall side to the outer wall side, then guided to the band insertion hole 26 along the outer wall, and then the band insertion hole. 26 is inserted from the outer wall side to the inner wall side (see also FIG. 1). The fixing work of the binding band 40 without the clamp may be performed in advance before fixing the binding band 30 with the clamp to the second inclined portion 23.

Next, as shown in FIG. 8 (and FIG. 9), the electric wire 50 is attached to the clampless binding band 40 fixed to the second inclined portion 23. As a result, the electric wire 50 is fixed to the second inclined portion 23 by the unclamped binding band 40 (corresponding to the above-mentioned "second method"). Here, since the band portion 41 is inserted through the two band insertion holes 25 and 26, the fixing force of the band portion 41 to the two band insertion holes 25 and 26 is relatively strong. Therefore, the fixing force of the clampless binding band 40 (hence, the electric wire 50) to the second inclined portion 23 becomes relatively strong. By the above procedure, the electric wire 50 is fixed to the second inclined portion 23 of the electric wire drawing portion 20 by using the binding band 30 with a clamp and the binding band 40 without a clamp.

<Action / effect>
As described above, according to the electric connection box 1 according to the embodiment of the present invention, the electric wire 50 can be fixed to the second inclined portion 23 of the electric wire lead-out portion 20 by using both the fixing directions of the first and second methods described above. .. Therefore, since both the advantages of the first method and the advantages of the second method can be enjoyed, it is easy to manage the extension length of the electric wire 50 from the electric wire drawing portion 20 to the outside, and the second electric wire 50 can be easily managed. It is possible to increase the fixing force to the inclined portion 23.

Further, unlike the electric connection box 1 according to the embodiment of the present invention, in the second inclined portion 23 of the electric wire drawing portion 20, the binding band 30 with a clamp is located closer to the tip end side of the electric wire 50 than the binding band 40 without a clamp. In the embodiment, when an external force acts on the electric wire 50 extending from the electric wire drawing portion 20 to the outside, the force derived from the external force acts on the binding band 30 with a clamp located on the tip side of the electric wire 50. In this case, the binding band 30 with the clamp is likely to separate from the second inclined portion 23 due to the relatively weak fixing force of the clamp 33 to the through hole 24 for fixing the clamp. On the other hand, in the second inclined portion 23 as in the electric connection box 1 according to the embodiment of the present invention, in the embodiment in which the binding band 40 without a clamp is located closer to the tip end side of the electric wire 50 than the binding band 30 with a clamp. When an external force acts on the electric wire 50 extending from the electric wire drawing portion 20 to the outside, a force derived from the external force acts on the clampless binding band 40 located on the tip side of the electric wire 50. In this case, it is unlikely that the clampless binding band 40 is separated from the second inclined portion 23 due to the relatively strong fixing force of the band portion 41 to the band insertion holes 25 and 26. Therefore, when an external force acts on the electric wire 50 extending from the electric wire drawing portion 20 to the outside, it becomes difficult to separate both the binding band 40 without the clamp and the binding band 30 with the clamp from the second inclined portion 23.

Further, according to the electrical connection box 1 according to the embodiment of the present invention, first, the electric wire 50 is fixed to the second inclined portion 23 by using the binding band 30 with a clamp by the above first method, and then. By the above-mentioned second method, the electric wire 50 is further fixed to the second inclined portion 23 by utilizing the binding band 40 without a clamp. Therefore, since both the advantages of the first method and the advantages of the second method can be enjoyed, it is easy to manage the extension length of the electric wire 50 from the electric wire lead-out portion 20 to the outside, and the electric wire 50 second It is possible to increase the fixing force to the inclined portion 23.
