DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A is a partial perspective view showing a state before an electric wire is converged in an electric wire converging structure of an electric junction box according to an embodiment of the present invention, and FIG. 1B is an enlarged view showing an electric wire converging state of the same structure. FIG. 2 is a partial perspective view, FIG. 2 is a cross-sectional view of the same structure in an electric wire converging state, and FIG. 3 is a perspective view showing the entire electric wire in the same structure in a converging state.

As shown in FIG. 1 to FIG.
The connection box main body 11 is made of a synthetic resin and has a box-like shape whose upper side is opened.
On the side, an electric wire routing path 13 is formed so as to extend in the longitudinal direction. The electric wire routing path 13 includes an outer wall 12, a partition wall 15 that is parallel to the outer wall 12 at a predetermined distance, and that stands upright from a bottom wall 14 of the connection box main body 11. And a partition wall 15 and a plurality of bridging pieces 16 formed integrally therewith, the front side of which is meandering in a plane L-shape.

A plurality of brackets (connector holding portions) 17 for holding a joint connector (connector) 20 are integrally formed on the outer wall 12 so as to extend above the wire routing path 13. As shown in FIG. 1A, each of the brackets 17 has a substantially box shape with an open top, and a hook wall 17b defined by a pair of slits 17a, 17a communicating with the opening side, and a hook wall 17b on the opening side. It has a pair of hook walls 17d, 17d in a plane L shape separated by a wide slit 17c communicating therewith, and is integrally provided on the outer surface side of the outer wall 12. A lock hole (not shown) is formed in the bottom surface 21 of the joint connector 20 so as to be fitted and held on the hook walls 17b and 17d of the bracket 17. Then, the plurality of electric wires 19 in the electric wire routing path 13 are pressed and converged by the bottom surface 21 of the joint connector 20 held by each bracket 17 via a lock hole.

Further, at a position facing each bracket 17 of the partition wall 15 constituting a part of the electric wire routing route 13,
A substantially trapezoidal spill prevention rib (electric wire holding means) 18 is integrally formed to protrude. The plurality of electric wires 19 include the electric wires 19 of the joint connector 20 held by each bracket 17.

According to the electric wire convergence structure of the electric junction box 10 of the above embodiment, when the joint connector 20 is fitted and held in each bracket 17, the plural electric wires 19 connected to the junction box main body 11 and each joint connector 20 are formed. Therefore, it is possible to simultaneously converge in the electric wire routing path 13 and between the spill prevention ribs 18 and the bottom surface 21 of each joint connector 20, thereby improving the workability.

Further, unlike the related art, since an arm or the like for converging the electric wire 19 is not required, the number of parts can be reduced correspondingly, and the overall cost can be reduced.
It is possible to eliminate the restriction of the shape of the mold for convenience.
Furthermore, since the spill-prevention ribs 18 are protruded at positions opposed to the respective brackets 17 at a predetermined distance, the plurality of electric wires 19 converged between the electric wire routing path 13 and the bottom surface 21 of each joint connector 20 are formed. The convergence state can be reliably held by each of the spill prevention ribs 18, and the plurality of electric wires 1
9 can be reliably prevented from being disturbed.

According to the above-described embodiment, the joint connector is brought close to the spill prevention rib. However, the bottom surface of the joint connector may be brought into contact with the tip of the spill prevention rib.

[0019]

As described above, according to the first aspect of the present invention, the electric wiring is performed by a simple operation of holding the connector in the connector holding portion provided above the electric wire routing path of the electric connection box. Multiple wires can be easily converged between the path and the bottom of the connector.
Since an arm or the like for converging the electric wires is not required, the number of parts can be reduced correspondingly, and the overall cost can be reduced.

According to the second aspect of the present invention, since the wire holding means is protruded at a position facing the connector holding portion of the wire routing path at a predetermined distance from the connector holding section, the wire holding means is held in the wire routing path and at the connector holding section. The convergence state of the plurality of wires converged with the bottom surface of the connector can be reliably maintained,
Disruption of the convergence state of a plurality of electric wires can be reliably prevented.
