DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector, and more particularly, to a protector which protects a bundle of wires such as a wire harness and to which a binding band which can be locked to a panel or the like of a vehicle body can be attached.

[0002]

2. Description of the Related Art Generally, a wire bundle such as a wire harness attached to a panel of a vehicle body or an electric device is provided with a protector for protecting the wire harness from the outside. In particular, locations subject to external forces (for example,
In the case of a wire harness attached to a light truck's cargo bed where there is a lot of lifting and lowering, use a circular or oval strong protector to securely protect the wire harness from the outside. I have.

[0003] As a conventional protector of this type, the protector shown in Figs. 4 and 5, reference numeral 1 denotes a wire harness, and a circular or elliptical protector 2 is attached to an outer peripheral portion of the wire harness 1. A binding band 3 is attached to the outer periphery of the protector 2. The binding band 3 is attached to the base 4, a band member 5 attached to the base 4, and windable around the outer periphery of the protector 2, 4, and a non-return locking body 7 which is locked to the opening 6 a of the vehicle body panel 6 so as not to come off.
It is composed of

[0004] To attach the wire harness 1 to which the protector 2 is attached to the vehicle body panel 6, the band member 5 is attached to the outer periphery of the protector 2 so as to be at an attachment position corresponding to the opening 6 a of the vehicle body panel 6. After winding and attaching the binding band 3 to the protector 2, the non-return locking member 7 is retained and locked in the opening 6a.

[0005]

However, in the protector 2 to which such a binding band 3 is attached, the protector 2 is crushed even if the binding band 3 is firmly attached to the protector 2 because the strength of the protector 2 is large. Since the binding band 3 did not bite into the protector 2, the binding band 3 laterally shifted in the longitudinal direction of the protector 2 or rotated in the circumferential direction.

For this reason, although the binding band 3 is attached to the protector 2 in advance in accordance with the position of the opening 6a, a displacement of the binding band 3 occurs, and the binding band 3 is moved to the opening. 6a, it is difficult to attach the wire harness, and the workability of attaching the wire harness deteriorates. Therefore, the present invention can prevent the binding band from being laterally displaced or rotated, can securely position the binding band on the partner member, and can easily attach the wire bundle to the partner member. The purpose is to provide a protector that can.

[0007]

According to the first aspect of the present invention,
In order to solve the above problems, a base, a band member attached to the base and capable of being wound around an outer peripheral portion of a protector, and a locking member which stands upright on the base and can be locked to a counterpart member. A tubular protector attached to an outer peripheral portion of the wire bundle, the pair of annular members protruding from the outer peripheral portion of the protector and extending in a circumferential direction of the protector. At least one set of protrusions is provided, and the annular protrusions are separated in the longitudinal direction of the protector so as to be able to hold the band member, and the front and rear ends in the extending direction are separated so as to be able to hold the base. It is characterized by.

In this case, the band member is positioned between the annular protrusions, and the band member is attached to the protector such that the base member is positioned between the front and rear ends of the annular protrusions. The band member can be prevented from laterally shifting by being sandwiched by the projections, and the band member can be prevented from rotating by sandwiching the base between the front and rear ends of the annular projection.

As a result, the binding band can be reliably positioned on the mating member, and the wire bundle can be easily attached to the mating member.
