Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric connection box used for wiring in an automobile.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional electrical connection box used for wiring in a vehicle has bolt insertion holes 22 formed in mounting plates 21 and 21 provided on both side surfaces of the electrical connection box main body 20. The bolts B, B are screwed into the nuts N, N welded to the vehicle panel A through the holes 22 to attach the electric junction box body 20 to the vehicle panel A.

[0003]

[Problems to be solved by the device]

 However, in the conventional electrical junction box configured as described above, the work of welding the nuts N, N to the vehicle panel A and the mounting plates 21, 21 provided on both side surfaces of the electrical junction box body 20 are performed. There is a problem that the work of inserting the bolts B, B into the bolt insertion holes 22, 22 and screwing them into the nuts N, N is troublesome and the workability is extremely poor.

As an electric junction box that solves the above problems, as shown in FIG. 6, a cap-shaped clip 23 is attached to the tip plate surface of a mounting plate 21 provided on one side surface of the electric junction box body 20. The cap clip 23 is fitted and locked in a locking hole a formed in the vehicle panel A, and a bolt insertion hole is formed in a mounting plate 21 provided on one side surface of the electrical junction box body 20. There is known an electrical connection box configured to attach the electrical connection box to the vehicle panel A by inserting a bolt B from 22 and screwing and tightening the nut N welded to the vehicle panel A.

By constructing the electrical junction box as described above, the nut N for welding to the vehicle panel A and the bolt B for attaching the electrical junction box to the vehicle panel A can be halved, and First, by fitting and locking the cap-shaped clip 23 in the locking hole a formed in the vehicle panel A, the work of attaching the electric connection box to the vehicle panel A becomes extremely easy. On the other hand, it is extremely difficult to remove the cap-shaped clip 23 fitted and locked in the locking hole a formed in the vehicle panel A, and maintenance and inspection after removing the electric connection box from the vehicle panel A There is a problem that maintenance such as replacement of the connection box is lacking.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electrical junction box that is economical and easy to maintain.

[0007]

[Means for Solving the Problems]

 The present invention relates to an electric connection box in which mounting plates to be attached to a vehicle panel are provided on both side surfaces of the electric connection box body. In the electric connection box body, a substantially L-shaped mounting plate is provided on one side surface of the electric connection box body. The locking projections and the stoppers, which are locked to the edges of the locking holes formed in the vehicle panel, are provided at the front end of the side surface of the vehicle, and the locking projections and the stoppers are provided on at least the front end surface of the mounting plate. The electric connection box is formed by forming a taper surface that does not come into contact with the hole edge when twist-locking the locking projection in the locking hole formed in the vehicle panel, thereby solving the conventional problems. Is.

[0008]

[Action]

 The locking projection provided on the tip side surface of the substantially L-shaped mounting plate provided on one side surface of the electric junction box body is fitted into the locking hole formed in the vehicle panel and twisted to engage the locking projection. Engage with the inner peripheral edge of the stop hole. By locking the locking projection on the inner peripheral edge of the locking hole, the stopper provided opposite to the locking projection abuts on the outer peripheral edge of the locking hole, and the electrical junction box is temporarily fixed to the vehicle panel. It Next, insert the bolts into the bolt insertion holes formed in the mounting plate on the other side of the main body of the electrical junction box, and tighten the nuts welded to the vehicle panel to secure the electrical junction box firmly to the vehicle panel. It can be attached to.

In addition, to remove the electric connection box attached to the vehicle panel, the bolts that fasten and fix the electric connection box to the vehicle panel are removed, and the locking projections are fitted and locked in the locking holes formed in the vehicle panel. The electrical junction box can be easily removed from the vehicle panel by twisting and removing in the opposite direction.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of the present invention, in which 1 is an electric junction box body and 2 is a substantially L-shaped attachment plate provided on one side surface of the electrical junction box body 1. A taper surface 2a is formed on at least a front end surface of 2 when the locking projection 3 described later is twist-locked in the locking hole a formed in the vehicle panel A, and does not come into contact with the hole edge of the locking hole a. Has been done. Denoted at 3 is a locking projection provided on the tip of the outer surface of the mounting plate 2, and 4 is a stopper provided so as to face the locking projection 3, and the tip of the inner surface facing the locking projection 3 of the stopper 4. A tapered surface 4a is formed on the. This tapered surface 4a is for preventing the inner end of the inner surface of the stopper 4 from coming into contact with the hole edge of the locking hole a when the locking projection 3 is twist-locked with the locking hole a formed in the vehicle panel A. Is. Reference numeral 5 denotes a mounting plate provided on the other side surface of the electric junction box body 1, and a bolt insertion hole 6 is formed in the plate surface of the tip portion of the mounting plate 5. Reference numeral 7 denotes an upper lid that is detachably attached to the electric junction box body 1, and 8 is a lower lid that is hingedly connected to the electric junction box body 1 so that the lower lid 8 is provided with a wire harness insertion hole (not shown). Has been.

In order to mount the electric connection box of the present invention having the above-described structure on a vehicle panel, as shown in FIG. 2, a substantially L-shaped mounting plate 2 provided on one side surface of the electric connection box body 1 is used. The locking projection 3 provided on the outer surface of the front end portion is fitted into the locking hole a formed in the vehicle panel A and twisted to be locked to the inner peripheral edge of the locking hole a. By locking the locking projection 3 on the inner peripheral edge of the locking hole a, the stopper 4 provided opposite to the locking projection 3 abuts on the outer peripheral edge of the locking hole a, so that the electrical junction box is connected to the vehicle. Temporarily fixed to panel A. Next, as shown in FIG. 4, the bolt B is inserted into the bolt insertion hole 6 formed in the mounting plate 5 provided on the other side surface of the electric junction box body 1, and the nut N welded to the vehicle panel A is screwed. Tighten and attach the electrical junction box to vehicle panel A. When the locking projection 3 is fitted and locked in the locking hole a formed in the vehicle panel A, for example, as shown in FIG. By forming the mounting plate 2 so as to abut the hole edge, it is possible to extremely effectively prevent backlash when the electric connection box is mounted on the vehicle panel A.

In order to remove the electric connection box attached to the vehicle panel A, the bolt B that tightens and fixes the electric connection box to the vehicle panel A is removed, and is fitted into the locking hole a formed in the vehicle panel A. The electric connection box can be easily removed by twisting the electric connection box to release the engagement of the engagement projections 3 which are engaged with each other.

[0013]

[Effect of device]

 According to the present invention, as described above, the nut welding to the vehicle panel A and the bolts for attaching the electric connection box to the vehicle panel A are reduced, and the electric connection box is securely fixed to the vehicle panel A. Since it can be attached to a box, it is economically advantageous, and since it can be easily removed, it has an excellent advantage that it can provide an electrical junction box with excellent maintainability.
