合する。Next, how the wire catching prevention means 5 prevents the wire 8 from being caught will be described. As shown in FIG. 1, a plurality of electric wires 8 are accommodated in the main body 1 by a desired method (for example, by hand). It suffices if all the electric wires 8 can be accommodated inside, but it is impossible to completely accommodate the electric wires 8. Figure 2
In some cases, the electric wire 8 ′ is lifted (jumped out) from the main body and is positioned on the insertion opening 11 of the hood 10, as shown in FIG. In that state, the lid 3 is attached to the main body 1. That is, the male lock member 4 of the lid 3 is inserted into and engaged with the female lock member 2.

底６へ導かれる。At this time, as shown in FIG. 2, the electric wire pushing surface 23 of the male lock member 4 pushes the electric wire 8'located on the insertion port 11 toward the hood 10. The movement of the wire pushing surface 23 is synchronized with the lid 3. As shown in FIG. 3, the wire pushing surface 23
The electric wire 8 ′ pushed out by the abutment hits the electric wire guiding surface 12 of the female lock member 2. At the same time as covering the main body 1 with the lid 3, the electric wire 8 ′ is pushed by the electric wire pushing surface 23, so that the electric wire 8 ′ is slowly guided (guided) into the main body 1 along the electric wire guiding surface 12. As shown in FIG. 4, the male lock member 4
When the locking step portion 22 of is engaged with the locking protrusion 13 of the female lock member 2, the electric wire 8 ′ is guided from the electric wire guiding surface 23 to the insole 6 of the main body 1.

During the process of assembling the main body 1 into the main body 1, the protruding electric wire 8 ′ can be automatically accommodated in the main body 1 by the electric wire catching prevention means 5. Therefore, it is possible to prevent the electric wire 8 ′ from being caught in the step of assembling the lid 3 to the main body 1, regardless of whether or not the electric wire 8 ′ is protruding from the main body 1. This allows the main body 1
There is no fear of damaging the electric wire 8 (8 ') therein, and the work of assembling the lid 3 to the main body 1 becomes easy.

自体が問題となる。When the hood 10 of the female lock member 2 is formed integrally with the outer surface 7c of the peripheral wall 7, the hood 1
If the wire guide surface 23 is formed on the surface 0, the peripheral wall 7 becomes an obstacle and the effect of the present invention cannot be obtained. That is,
If the peripheral wall 7 is cut out along with the formation of the wire guide surface 23 on the hood 10, the strength of the female lock member 2 (hood 10) itself becomes weak. On the other hand, when the hood 10 of the female lock member 2 is arranged on the inner surface 7b of the peripheral wall 7, the rate at which the electric wire 8 is placed (positioned) in the insertion port 11 increases, so that the female lock member 2 is arranged. The location itself matters.

It is not very popular. Therefore, when the lid 3 is assembled to the main body 1, the possibility that the electric wire 8 ′ is caught becomes low, so that the necessity of providing the electric wire catching means 5 is reduced. In addition,
This embodiment can also be used for an electric connection box (J / B) not shown, a protector for protecting a wire harness, and the like.

The insertion hole of the hood is in the same plane as the free end of the peripheral wall of the main body. On the other hand, the engaging arm of the male lock member is inserted into the hood, and the engaging arm has a flat tip on the insertion side. for that reason,
By forming the wire catching prevention means on the female lock member and the male lock member, the wire can be pulled back into the main body while the lid is being assembled to the main body. This can prevent the electric wire from being caught between the engaging arm of the lid and the hood of the main body. Therefore, after the male lock member is engaged with the female lock member, the electric wire that has jumped out (lifted) out of the main body can be reliably accommodated in the main body. In addition, electric wire biting means
Is tilted inward toward the hood of the female locking member.
The inclined wire guide surface and the engaging arm of the male lock member
The guide surface and the wire pushing surface inclined in the opposite direction. So
Therefore, before assembling the lid to the main body, put it on the hood you missed.
Push the positioned wire to the wire guide surface side by the wire pushing surface.
It can be put out and easily guided into the main body along the wire guide surface.
It This prevents the wires from getting caught after assembly.
It That is, if you miss the electric wire that jumps out of the main unit,
The electric wire can be reliably housed in the main body after assembly. Obey
Assembly is easier than before and the electric wire is
You can eliminate the worry of crushing and breaking the wire.
