2. Description of the Related Art A wire harness protector has a U-shaped groove shape for accommodating an electric wire bundle of a wire harness.
Various shapes such as a drum type to be mounted on the outer periphery of the wire harness are known. The drum protector 1 (see FIG. 2) has a structure in which a peripheral wall of a rubber short tubular body that penetrates the hollow portion 4 is provided with a cutout portion 3 that is opened in the longitudinal direction of the tubular body to open and close. By opening the incision 3 and fitting the wire harness 12 onto the outer periphery of the wire harness 12, the clamp member 10 is attached to the outer periphery of the drum protector 1 in the mounting posture, and the clamp member 10 is fixed to the vehicle body 13 or the like. The wire harness 12 is maintained in the disposition posture in the vehicle body / apparatus, and the clamp member 10 is indirectly fixed to the wire harness 12.
It is designed to protect the outer circumference of.

In the wire harness 12 arranged and locked by the drum protector 1, a strong sliding load is generated at the locking point of the drum protector 1 due to an external force due to traveling vibration of the vehicle body. To prevent the stop point from collapsing, wire harness 12
The tape winding 14 is applied to the outer circumference of the
After setting the drum protector 1 on top,
A special measure for increasing the fixing force is taken to improve the fixing force of the drum protector 1 with respect to the wire harness 12 by winding the tape 14 around the outer periphery of the drum protector 1 in the set posture and locking the incision 3. .

[0004]

The drum protector 1 having the above-described conventional structure is mounted on the wire harness 12 in the following manner.
Since a special measure for increasing the fixing force by the tape winding 14 is required, the work for mounting the wire harness 12 is complicated and troublesome, and the fixing force to the wire harness is insufficient due to the lack of the tape winding 14. However, an external force during traveling of the vehicle body may break the point at which the wire harness 12 is locked to the vehicle body, and the function of the wire harness protector may be deteriorated. The present invention provides a drum protector that solves the above-mentioned drawbacks of the prior art.

[0005]

The wire harness protector of the present invention which solves the above technical problems is "a rubber short tubular body, and the wire harness is inserted from an incision formed by cutting the peripheral wall in the longitudinal direction of the tubular body. A drum-type protector for a wire harness, which is mounted on the wire harness and is arranged and locked on the vehicle body / apparatus by a clamp member attached to the outer periphery of the wire harness from the one side edge of the cutout portion. A rubber winding band having a band length and a band hole that extends in the radial direction of the pipe body and that makes a complete circle around the outer periphery of the pipe body is provided, and the outer periphery of the pipe body is engaged with the band hole. Protrusions are provided so that the winding band can be wound around the outer periphery of the tubular body from the other side edge of the incision portion, and a locking tightness posture can be locked by the engagement between the locking protrusion and the band hole. It has a structure "that.

[0006]

The drum protector for a wire harness of the present invention having the above-described winding band and the locking mechanism for the winding band is wound around the outer circumference of the protector tubular body and is tightly locked by elastic force. Therefore, the tightening force acts as an elastic force of an evenly distributed load that extends around the outer circumference. Therefore, the drum protector is uniformly pressed against the outer circumference of the bare wire harness penetrating the protector, and the locking force of the drum protector to the wire harness can be sufficiently secured. From the above, the "slip tape winding" around the outer periphery of the wire harness in the prior art becomes unnecessary, and the wrapping band can be wrapped by closing the incision part, so that the incision part by the elastic band pressure by the wrapping band. Also becomes a locked state, and the conventional tape winding for locking the incision is also unnecessary.

Embodiments will be described in detail below based on embodiments. That is, referring to FIG. 1 showing a drum-type protector 1 of one embodiment of the present invention applied to a protector attached to a wire harness for an automobile, from a protector body 2 of a rubber short tube having a hollow portion 4 penetrating therethrough, Nari, this protector body 2
Has a cutout portion 3 which is incisable in the longitudinal direction of the tubular body in the longitudinal direction of the tubular body so as to be separable. The cutout portion 3 is opened, the wire harness 12 is put in the hollow portion 4, and the wire harness 12 is mounted on an outer peripheral portion of the wire harness 12. In the drum type protector 1, a band lock mechanism including a winding band 5 that can be wound around the outer periphery of the protector body 2, a band hole 6 provided in the winding band 5, and a locking protrusion 7 on the protector body 2 side that meshes with the band hole 6. Is provided.

That is, the winding band 5 is made of rubber and is integrally formed by extending from one side edge 8A of the incision 3 in the radial direction of the protector body 2 and winding at least one circumference around the outer circumference of the protector body 2. In addition to having a wearable band length, a plurality of band holes 6 arranged in the longitudinal direction of the band at a required pitch are formed in the front half portion.

On the other hand, on the outer circumference of the protector body 2 and above one side edge 8A of the band base end of the winding band 5, a member is fitted in the band hole 6 to lock the winding posture of the winding band 5. A stop projection 7 is provided, and the band hole 6 and the locking projection 7 are provided.
Thus, a band lock mechanism that locks the winding tightening posture of the winding band 5 around the protector body 2 is configured.

In the above-mentioned drum protector 1 (see FIG. 1C), the incision 3 is opened, and the bare wire harness 12 which does not take a special anti-slip measure such as tape winding is inserted into the hollow part 4. The wire harness 12 is attached to the wire harness 12 at a predetermined position. Subsequently, the winding band 5 is wound around the outer periphery of the protector body 2 from the direction of the other side edge 8B of the incision portion 3 and tightened, and the band hole 6 is selected to be engaged with the locking projection 7 and wound. Lock the wrapping and tightening posture of the dressing band 5. The excess portion of the tip of the winding band 5 is cut after the winding and tightening.

After that, a known clamp member 10 having plate-shaped mounting portions 11 at both ends of a notched arc-shaped holding portion 9 is attached to the outer periphery of the winding band 5 in the winding tightening posture, and the clamp member is attached. The wire harness 12 for the vehicle body 13
The holding posture of the wire harness 12 is retained and locked, and the outer circumference of the wire harness 12 is protected by the protector body 2.

The band type protector 1 of the embodiment shown in FIG.
Has the above-mentioned action, and the wrapping band 5 wound around the protector body 2 and tightly locked is present around the outer circumference of the protector body 2 almost once, so that the elastic force can be exerted toward the center of the protector body 2. Therefore, the protector body 2 which receives the tightening force as a uniformly distributed load with a uniform outer circumference exerts a strong locking force on the outer circumference of the bare wire harness 12 which does not have any special anti-slip measures such as tape winding. At the same time, the incision portion 3 is locked by the tightening force of the winding band 5, so that the protector body 2 is connected to the wire harness 12.
Even when a strong external force is generated at the locking point of the wire harness 12 due to vibration of the vehicle body running or the like due to a sufficient locking force, the mounting posture of the drum-type protector 1 is extremely unlikely, and the protector function is improved. Is stable. Then, the conventional complicated work of the tape winding 14 can be omitted, and the occurrence of a defective protector due to the defective tape winding 14 can be prevented.
