Description

  The present invention relates to a protector that is externally mounted on a wire harness routed in an automobile.

A wire harness routed in an automobile is penetrated by a box-shaped protector made of a resin-molded product in a required routing area in order to strengthen the route regulation and the protection function of important wires.
The protector is integrally molded with a vehicle body locking clip or is assembled with a separate vehicle body locking clip to be locked and fixed to a fixing member such as a vehicle body panel.

  On the other hand, in order to fix another wire harness that passes through the position where the protector is disposed, the locking clip may be locked to the protector fixed to the vehicle body panel. Therefore, in this case, the protector is provided in advance with a clip locking portion attached to another wire harness.

As shown in FIGS. 5A and 5B, this type of protector has a locking hole 2a formed in a lid 2 hinged to a bowl-shaped protector body 1, while the protector body 1 side has a hole. A partition wall 1c that forms a clip housing space S1 is provided from the bottom wall 1a along the side wall 1b.
Therefore, the vehicle body locking clip 5 attached to another wire harness W / H1 that passes through the arrangement position of the protector 3 is inserted and locked in the locking portion 5a through the locking hole 2a, so that the protector 3 Can be held in the routing position.
As described above, the partition wall 1c is provided in the protector body 1 because the locking portion of the clip 5 inserted from the locking hole 2a by the wire group of the wire harness W / H2 penetrating into the protector body 1. This is to prevent 5a from interfering with the locking hole 2a.

  However, when the partition wall 1c is provided inside the protector main body 1, as shown in FIG. 6, the insertion space of the wire group of the wire harness W / H2 that penetrates into the protector main body 1 at the portion where the partition wall 1c is provided. The volume of S2 decreases. Therefore, even if the wire insertion space of the other part of the protector body 1 is large, there is a problem that the wire insertion volume of the protector is defined by the insertion space S2 provided with the partition wall 1c.

Moreover, as what enabled another wire harness to be fixed to a protector, the protector 6 shown in FIG. 7 is provided by Unexamined-Japanese-Patent No. 7-75233 (patent document 1).
The protector 6 has a protrusion 2c ′ protruding from the upper surface of the lid 2 ′, and a fitting hole 2d ′ into which a clip is fitted is provided in the protrusion 2c ′.

However, in the protector 6, the convex portion 2 c ′ protrudes from the lid 2 ′, and the clip is locked to the convex portion 2 c ′, so that the space occupied by the protector 6 is increased by the height of the locking portion of the clip. To increase. In recent automobiles, the mounting space for the wire harness is often limited due to reasons such as a rapid increase in the number of mounted parts, and it is not preferable to provide the convex portion 2 ′ that increases the size of the protector. And when a clip is latched to convex part 2c ', there also exists a problem which the latching stability of a clip falls.
Japanese Patent Laid-Open No. 7-75233

  The present invention has been made in view of the above problems, and securely locks and fixes clips attached to other wire harnesses without increasing the size of the protector and without reducing the wire insertion volume in the protector. The challenge is to make it possible.

In order to solve the above-mentioned problems, the present invention allows a wire harness to be routed in an automobile to be inserted inside and functions as a fixing material for another wire harness by locking a clip attached to the other wire harness. Protector,

There is provided a protector characterized in that it does not interfere with the locking portion.

  As described above, when the interference prevention rib is provided so as to surround the locking hole of the clip drilled in the lid of the protector, the height of the interference prevention rib is set to a height corresponding to the height of the locking portion of the clip. Therefore, the space of the protector body below the interference prevention rib can be used as a wire insertion region. Therefore, the wire insertion space can be greatly increased as compared with the case where the partition wall is formed from the bottom wall of the protector body as shown in FIG. In addition, since the wire group that passes through the protector body has an interference prevention rib, it passes under the interference prevention rib and does not interfere with the clip's locking part inserted from the locking hole, preventing the clip from coming off. it can.

Also, as described above, locking hole bored in the lid is provided near one end in the width direction of the lid, the interference prevention ribs is a semi-annular frame surrounding the locking hole, the lid protector body In the closed state, the interference prevention rib of the semi-annular frame contacts the side wall of the protector body to form a sealed space, and the height of the interference prevention rib is equal to or higher than the height of the locking portion of the clip. .

As described above, the height of the interference prevention rib is equal to or higher than the height of the locking portion of the clip, preferably approximately the same. That is, the smaller the protrusion of the interference prevention rib, the larger the wire insertion space. Therefore, the height of the interference prevention rib is approximately equal to the height of the engaging portion of the clip protruding from the engaging hole into the protector body. It is preferable to have the same minimum height.
Further, the interference prevention rib is a semi-annular frame, and is configured to form a closed cross-section by contacting the side wall of the protector body in the closed state of the lid, and may be provided at a corner along the side wall of the protector body. It does not get in the way of the wires that pass through the inside of the protector body.

The lid of the protector may be a lid integrally formed on one side wall of the protector body through a thin hinge portion so as to be opened and closed, or may be a lid separate from the protector body.
The clip attached to another wire harness that is locked to the protector may be a band clip that wraps a band portion around the wire harness, or may be a board-type clip that is taped and fixed to the wire harness. In either case, a shaft portion is erected from a fixed portion to the wire harness, and a blade-like locking portion is projected from the tip of the shaft portion. Therefore, an interference prevention rib having a height corresponding to the height of the blade-shaped locking portion may be provided so as to protrude from the inner surface of the lid.
The shape of the clip is not limited to the above shape, and may be other shapes, and the height of the interference prevention rib provided on the inner surface of the lid is equal to or greater than the protruding amount of the locking portion inserted from the locking hole of the lid. Just keep it as.

  As described above, by providing an interference prevention rib surrounding the locking hole on the inner surface of the lid of the protector in which the locking hole of the clip attached to another wire harness is formed, the inside of the protector main body has a wire insertion space. The amount of decrease can be minimized. Therefore, an increase in the size of the protector can be suppressed, and other wire harnesses can be locked and fixed to the protector via the clip in a stable state.
