Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial Field of Application] The present invention relates to an improvement in a device for attaching an electrical junction box to a vehicle body integrally with a wire protector that holds a wire bundle (wire harness).

[Conventional technology and problems]

When installing and fixing electrical junction boxes, such as fuse boxes, relay boxes, junction boxes containing electronic circuit units, etc. to the vehicle body,
It is required to assemble it together with the connecting wire in as little space as possible.

Figures 4 to 6 show conventional electrical junction box mounting devices. In the figures, a is a bracket fixed to a panel P of a vehicle body, etc., and in the center is a bracket for fixing an electrical junction box c. A stop hole b is provided. A wire protector d having a U-shaped cross section is attached to the upper side wall of the electrical junction box c.
An electric wire bundle W including connecting electric wires w is held.
The protector d is provided with a cylindrical insertion guide e for the bracket a, perpendicular to the axial direction of the wire bundle W. One opening end _e1 of the insertion guide e is formed into a tapered shape that widens into a funnel shape and narrows toward the other opening end _e2 , and an electrical connection box c is formed at the opening end _e2 .
A fitting cylinder f provided in the housing is fitted together with a locking means (not shown). Further, a locking arm g having a protrusion _g1 that fits into the locking hole b of the bracket a is protruded within the fitting tube f.

According to the above configuration, as shown in FIG.
The fitting cylinder f is inserted and locked into the open end _e2 of the protector d, and the other open end _e1 is inserted into the bracket a to lock the locking arm g. direction, protector d
and electrical connection box c are stacked on top of each other.

As a result, the electrical connection box c protrudes toward the indoor side from the panel P (distance H), narrowing the indoor space and creating wasted space.

The object of the present invention is to mount an electrical junction box and its wire protector on a vehicle body in a compact form, thereby eliminating wasted space and expanding the effective space inside the vehicle.

Structure of the Invention [Means for Solving Problems] To explain with reference to the drawings, the device for attaching an electrical junction box to a vehicle body according to the present invention is as shown in Figs. 1 to 3. 1 and the wire protector 2 are provided with split insertion guides 6a and 6b facing each other perpendicularly to the fitting locking means 4 and 5 of the two and the axial direction of the wire bundle W. A flexible locking arm 7 that fits into a locking hole 3a provided in a bracket 3 fixed to the vehicle body is provided inside one of the locking arms 6b, and the electrical connection box 1 and the wire protector 2 are connected to the fitting locking means 4, 5, the opposing insertion guides 6a and 6b form one insertion guide 6, and this insertion guide 6 is inserted into the bracket 3 to removably lock the locking arm 7. It is characterized by

In FIG. 1, the wire protector 2 is a gutter-shaped body with a U-shaped cross section with an open front, but it may also be a cylindrical body with a closed front.

The fitting lock means 4, 5 have the following construction. That is, the electrical connection box 1 of the wire protector 2
A drawer-type insertion member 4b having grooves 4a at both ends is formed in a bulging manner on both sides of the connection surface 2a, and a drawer-type insertion member 4b can be freely attached to and detached from the opposing side wall 1a of the electrical connection box 1. Support members 4c, 4c fitted to
is provided in a protruding manner, and the drawer type insertion member 4b and the support member 4c form a fitting means 4. Further, a protrusion 5a is provided between the grooves 4a and 4a of the drawer type insertion member 4b.
A locking groove 5c that engages with the protrusion 5a is provided between the opposing support members 4c, 4c, and a locking groove 5c that engages with the protrusion 5a is provided between the flexible locking arm 5b and the locking groove. 5c forms the locking means 5. It goes without saying that the members constituting the fitting locking means 4, 5 may be provided on opposite sides.

Split type insertion guide 6a that constitutes the insertion guide 6,
6b is a tapered surface 6c whose inner surface becomes gradually narrower.
This serves as a guide to ensure that the inserted bracket 3 and locking arm 7 are fitted together.

The locking arm 7 has a locking protrusion 7a at the center of its upper surface that fits into the locking hole 3a of the bracket 3, and its tip extends to form a release lever 7b.

In FIG. 1, reference numeral 8 denotes another bracket fixed to the panel P, and a bolt 10 is inserted into a hole in a mounting plate 9 protruding from the lower side of the electrical connection box 1 and is tightened and fixed.

[Effect]

In the wire harness assembly process, when the electrical junction box 1 and the wire protector 2 are connected by the fitting lock members 4 and 5, one insertion guide 6 is formed by the opposing split insertion guides 6a and 6b. A wire bundle W including the wires w connected to the electrical connection box 1 is fixed to the wire protector 2 with tape or the like.

Next, in the vehicle assembly process, the insertion guide 6 is inserted into the bracket 3 of the panel P, as shown in FIG. The bracket 3 enters while being guided by the tapered surface 6c and comes into elastic contact with the locking arm 7. When the bracket 3 advances further, the locking protrusion 7a fits into the locking hole 3a and is locked. In this state, as shown in FIG. 1, the mounting plate 9 of the electrical junction box 1 is tightened and fixed to another bracket 8 with bolts 10.

As is clear from Fig. 3, the split mold insertion guide 6
The insertion guide 6 formed by a and 6b has a length comparable to the thickness (or depth) of the electrical junction box 1 or the wire protector 2, and the electrical junction box 1 is installed close to the panel P. . Therefore, the distance between the electrical connection boxes 1 protruding from the panel surface is greatly reduced, and the effective space within the vehicle interior is increased.

Effects of the invention As explained above, according to the invention, a split insertion guide for a bracket fixed to a vehicle panel, etc. is provided on the connection surface of the electrical junction box and the wire protector, and the two are connected together. Since two insertion guides are formed, it can be installed close to the panel, and the effective space in the vehicle interior can be expanded.
