Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a technique for attaching an electrical component storage box for storing electrical components such as a junction box and a connector to a striatal body protector.

[Conventional technology]

A protector and a lid having a U-shaped cross section are sometimes attached to a vehicle or the like with the lid facing downward. A conventional technique for fixing an electrical component storage box such as a junction box to such a protector or for inspecting a junction box will be explained with reference to FIGS. 3a and 3b.

In FIG. 3a, an opening 3 is formed in the protector main body 1 from the opening side end of the side wall 1a thereof, through which the wire harness passes. A slide guide 4 is formed on both sides of the opening 3, and a stopper 4c is formed at the lower end of the slide guide 4, and an engaging protrusion 5 is formed near the slide guide 4. On the other hand, the electrical component storage box 6 is provided with a guide member 7 that is inserted into the groove of the slide guide 4 and an engaged member 8 that engages with the engagement protrusion 5 .
A junction box 12 is fitted into the electrical component storage box 6, and a branch wire bundle 13 of a wire harness routed within the protector body 1 is connected thereto.

To fix the electrical component storage box 6 to the protector body 1, the protector body 1 is placed on a wiring board with the opening surface 1b facing upward, and a wire harness is routed to the protector body 1. After that, the lid body 2 is fixed to the protector body 1, and the branch wire bundle 13 of the junction box 12 is led out to the opening 3 of the protector body 1. Next, the junction box 12 is fixed in the electrical parts storage box 6, and the cover 9
is locked by male lock 10 and female lock 11, and the lid is closed. Then, the guide member 7 of the electrical component storage box 6 is inserted into the groove of the slide guide 4 from above in FIG. 3a. To fix the two, the tip of the guide member 7 is inserted into the groove of the slide guide 4, and then the electrical component storage box 6 is pushed down to bring the upper end of the guide member 7 into contact with the stopper 4c of the slide guide 4. At this time, the engaging protrusion 5 on the protector body 1 side and the engaged protrusion 8 are engaged, and the electrical component storage box 6 is fixed to the protector body 1.

When the protector assembled as described above is to be fixed to a vehicle, it is fixed with the lid 2 facing downward as shown in FIG. 3B due to the wiring of the wire harness. Further, when inspecting the junction box 12 after it has been assembled into a vehicle, the male lock 10 and female lock 11 of the cover 9 of the storage box 6 are removed.

[The problem that the idea attempts to solve]

However, in such a structure, the electrical parts storage box 6
Since the stopper 4c is located above when the vehicle is assembled as shown in FIG. If it comes off, the electrical parts storage box 6 will fall off. Alternatively, even if both the cover 9 and the junction box 12 are partially locked, the electrical component storage box 6 or the junction box 12 may fall down. Especially electrical parts storage box 6
However, if it falls off when it is placed near the driver's seat, there is a risk that it will interfere with driving.

This idea was made in view of the above facts.
It is an object of the present invention to provide a fixing structure for an electrical component storage box that will not fall off immediately even if the engagement by an engagement member or the like is disengaged.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a fixing device for fixing an electrical component storage box to a protector consisting of a protector body for a linear body having a U-shaped cross section and a lid body that is locked to the protector body. In the structure, a wiring opening for passing electric wires is formed in the side wall of the protector main body, a slide guide and an engaging means are provided on both sides of the opening, and a sliding member that engages with the slide guide and the above-mentioned engaging means are provided in the electrical parts storage box. An engaged means that is engaged with the coupling means is provided, and a support wall that supports the electrical component storage box is provided on the lid.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. It should be noted that the same parts as in the prior art will be described with the same reference numerals. FIG. 1a shows an exploded perspective view of a state in which the device is assembled into a vehicle, and FIG. 1b shows a state in which it is attached to a vehicle after being assembled. In these figures, 1 is a protector main body, which is formed by injection molding of resin or the like. This cross section is U-shaped, and side walls 1a are erected on both sides. Side wall 1a
A wiring opening 3 through which a branch wire bundle 13 of the wire harness is passed is formed in the protector body 1 in communication with the opening surface of the protector body 1. Slide guides 4 having an L-shaped cross section are erected on both sides of the wiring opening 3, and a guide groove 4a is formed between the slide guides 4 and the side wall 1a. In addition, in FIG. 1a, a stopper 4b is provided at the upper end of the slide guide 4. Between the slide guide 4 and the wiring opening 3,
A protrusion 5 is formed as an engaging member. The projection 5 has a diagonal view 5a at the bottom of the figure.

2 is a resin lid that has a shallow U-shape.
It is locked to the protector main body 1 by a locking means (not shown). An opening 2b is formed in the side wall of the lid 2 at a position corresponding to the wiring opening 3, and the opening 2b is formed in the side wall of the lid 2.
The support wall 2a of the electrical parts storage box is placed almost parallel to the bottom surface of the
is installed protrudingly.

Reference numeral 6 denotes a resin electrical parts storage box for accommodating a junction box and the like, and slide members 7 to be inserted into the guide grooves of the slide guide 4 are formed on both sides of the mounting surface. The slide member 7 includes
A protrusion 8 as an engaged member to be engaged with the protrusion 5 is provided in a protruding manner.

A cover 9 is also formed on the electrical component storage box 6 and is coupled with a hinge. This cover 9 is locked by a male lock 10 formed on the lid fitting into a female lock 11 formed on the electrical parts storage box 6.

Reference numeral 12 denotes a junction box, into which a large number of electrical components such as connectors and relays are incorporated, and to which a branch wire bundle 13 from the wire harness is connected.

To fix the electrical component storage box 6 to the protector body 1, the protector body 1 is placed on a wiring board with the opening surface 1b facing upward, and a wire harness is routed to the protector body 1. After that, the lid body 2 is fixed to the protector body 1, and the branch wire bundle 13 of the junction box 12 is led out to the opening 3 of the protector body 1. Next, the junction box 12 is fixed in the electrical parts storage box 6, and the cover 9
is locked by the male lock 10 and female lock 11 to close the lid, and the guide member 7 of the electrical parts storage box 6 is inserted into the groove of the slide guide 4 from below in FIG. 1a. Since the slide guide 4 has an L-shaped cross section, the electrical component storage box 6 is held in the slide guide 4, and slides into the guide groove 4a without being able to separate from the protector body 1, and the stopper 4b It comes into contact with and is prevented from progressing. At this time, the protrusion 8 as an engaged member provided on the guide member 7 rides over the slope 5a of the protrusion 5 as an engaging member and engages with it. The electric component storage box 6 is thereby also prevented from moving backwards and is fixed to the protector body 1. When the protector assembled as described above is to be fixed to a vehicle, it is fixed with the lid 2 facing downward as shown in FIG. 1B due to the wiring of the wire harness.

Figure 2a shows a cross-section in the fixed state. In the figure, reference numeral 14 denotes a wire harness, which is a trunk bundle of branch wire bundles 13 routed to the junction box 12. Junction Box 12 is
It is fixed to a fixing protrusion 6a formed inside the electrical component storage box 6.

The electrical component storage box 6 fixed to the protector main body 1 rides on a support wall 2a formed on the lid body 2, and is also supported by this. Therefore, even if the guide member 7 climbs over the stopper 4b due to vibrations of the vehicle after installation, it will still be supported by the support wall 2a and will not fall off. Furthermore, even if the projections 5 and 8 are disengaged, the guide groove 4a of the slide guide 4 is long, and there is resistance due to the weight and friction of the electrical component storage box 6 itself, so the slide guide 4 will be able to fly out from here against these resistances. There's no fear. On the other hand, since the cover 9 of the electrical parts storage box 6 is also supported by the support wall 2a, it will not open easily even if the male and female locks 10, 11 are disengaged.

The support wall 2a has a length H and a thickness t set appropriately so that the cover 9 can be opened, and has sufficient flexibility. Therefore,
If the junction box 12 or the like inside the electrical parts storage box 6 breaks down, it can be repaired by bending the support wall 2a outward as shown by the chain line in FIG. 2a and prying open the cover 9. As an example of the size of the supporting wall 2a in this case, in the case of the size of a protector used in a normal automobile, the length H shown in Fig. 1a is preferably about 10 mm, and the thickness t is about 1 mm. . In addition, when locking the cover 9 after repair, the protector body 1, the lid body 2, the electrical parts storage box 6, etc. are made of resin and are flexible, so the cover 9 can be locked under the support wall 2a. It can be inserted and locked. Or, since the supporting wall 2a is thin,
It can also be locked from the outside of the support wall 2a as shown in Figure 2b.

[Effect of idea]

As explained above, according to the present invention, in a fixing structure for fixing an electrical connection box to a protector having a U-shaped cross section, the electrical component storage box is fixed by the engaging means and supported by the support wall provided on the lid. Since it has a double structure, even if the engaging means comes off due to vibration after installation, the electrical parts storage box can be prevented from falling off.
