Description

TECHNICAL FIELD The present invention relates to a wire harness holder, and more particularly to a wire harness holder around which a corrugated tube is wound.

(Prior Art) Conventionally, there is a holder 40 shown in FIG. 9 for disposing this kind of wire harness W in a state of being protected by the corrugated tube 3, and this holder 40 has two substantially half halves. A circular holding member 41 is connected via a hinge 42 to form a substantially cylindrical mating type to hold the corrugated tube 3. The corrugated tube 3 is provided on both edges of the inner peripheral surface of the holding member 41. Ribs 43 that engage with the uneven surfaces 3a and 3b are formed over the entire edge portion.

(Problems to be Solved) However, in this configuration, for example, the corrugated tube 3 that holds the wire harness W is provided with the notch c in the vertical split direction as shown in FIG. Is inserted and taping T is performed at a predetermined interval. At the time of taping T, the surface of the notch c relatively moves and the notch c is twisted in a substantially spiral shape. In some cases, the cut c may be on the lower side. Therefore, for example, when the wire harness W holding the corrugated tube 3 is attached to the bracket 2 or the holder 40 that is previously fixed through the attachment hole in the engine room of the vehicle, etc., if the notch c faces downward, Steam is generated by heat or the like, and this steam forms a rib on the holding member 41 of the holder 40.
There is a problem that water droplets accumulate in the concave portions between 43 and enter into the corrugated tube 3 through the notch c, and further propagate along the electric wire to reach the branch wire connecting portion, causing an electrical trouble, etc. Therefore, paying attention to the directionality of the cut c has a problem that workability is significantly deteriorated.
Further, in order to discharge the water droplets, it is considered to open a window portion in the holding member 41, but since the mounting height is restricted in the arrangement portion, the locking leg portion 31 shown in the holding member 41 is provided. Since it is necessary to provide and arrange it, there is a problem that the window cannot be opened.

The present invention has been made in order to solve the above-mentioned conventional problems, in which water droplets do not collect, electrical troubles can be prevented, and workability can be improved. An object of the present invention is to provide a holder for a wire harness that does not impose restrictions on the parts.

(Means for Solving the Problems) In order to solve the above technical problems, the present invention provides a substantially semi-circular mounting member and a holding member having a substantially cylindrical shape having a predetermined diameter via a thin hinge portion. Ribs that engage with the corrugated surface of the corrugated tube that protects the outer circumference of the wire harness are provided on the inner peripheral surfaces of both members, and the mounting portion is provided on the lower surface of the mounting member or on the opposite side of the hinge portion. A holder for a wire harness in which a drainable slit is provided at least at one location in the rib of the attachment member at a position where it does not interfere with the molding of the attachment portion.

A retainer having a rib on its surface that engages with the corrugated surface of the corrugated tube that protects the outer periphery of the wire harness, and a mounting portion formed on the lower surface of the mounting member or on the opposite side of the hinge portion to form the mounting portion. Since the rib of the mounting member, which is a position not interfering with, is provided with at least one slit capable of draining water, the notch of the corrugated tube is mounted on the lower side, and the temperature in the engine room is maintained. Even if the water vapor rises to generate water vapor and this water vapor penetrates into the holder to form water droplets between the ribs of the mounting member, the ribs have corresponding slits, so the water droplets are the same. Since water will not drain from the slit to the outside of the holder and water droplets will not accumulate inside the holder, it is possible to prevent water from entering the corrugated tube through the notch and solve the electrical connection trouble. Since it is not necessary to pay attention to the taping work of the corrugated tube and the direction of attachment of the notch holder, etc., the wire harness can be easily assembled ... The work efficiency can be improved, and in particular, Since the drainage slit is provided on the rib side, molding can be performed without any restrictions on the mounting part, and the height, space, etc. of the mounting part can be dealt with. The degree of freedom in molding can be improved.
