Description

本発明は、車両等に配索されるワイヤーハーネスが挿通されることによりワイヤーハーネスを保護するプロテクタに関する。 The present invention relates to a protector that protects a wire harness by inserting a wire harness routed in a vehicle or the like.

特許文献１には、ワイヤーハーネスが挿通され、このワイヤーハーネスを保護するプロテクタが提案されている。このプロテクタは、プロテクタ本体と、プロテクタ本体の開口部を閉塞する蓋材とで形成されている。プロテクタ本体は、底壁部と、この底壁部の両側から同方向へ立ち上がる側壁部とで形成され、側壁部間にワイヤーハーネスを内部に配索する開口部が形成されている。 In Patent Document 1, a wire harness is inserted and a protector for protecting the wire harness is proposed. This protector is formed of a protector body and a lid member that closes the opening of the protector body. The protector body is formed of a bottom wall portion and side wall portions that rise in the same direction from both sides of the bottom wall portion, and an opening portion is formed between the side wall portions to route the wire harness.

そして、開口部からワイヤーハーネスを側壁部間に挿通させ、蓋材により開口部を閉塞することでワイヤーハーネスがプロテクタ本体内に挿通される。また、開口部を閉塞する蓋部材によってプロテクタ本体内からのワイヤーハーネスの抜けが阻止されている。このようにワイヤーハーネスが内部に挿通されたプロテクタは、車体固定部により車体に固定される。 And a wire harness is penetrated in a protector main body by inserting a wire harness between side wall parts from an opening part, and obstruct | occluding an opening part with a cover material. Further, the wire harness from the inside of the protector body is prevented from coming off by the lid member that closes the opening. Thus, the protector with the wire harness inserted therein is fixed to the vehicle body by the vehicle body fixing portion.

従来のプロテクタでは、プロテクタ本体内に挿通されるワイヤーハーネスの径が変化すると、すなわちワイヤーハーネスを構成する複数本の電線の本数が変化すると、プロテクタ本体を構成する底壁部と両側壁部間の電線の収容率が変化して、ワイヤーハーネスと底壁部、両側壁部との間に隙間が生じるため、振動によりワイヤーハーネスと底壁部、両側壁部、蓋材とが干渉し、異音が発生するおそれがある。 In the conventional protector, when the diameter of the wire harness inserted into the protector body changes, that is, when the number of the plurality of electric wires constituting the wire harness changes, between the bottom wall part and both side wall parts constituting the protector body. Since the capacity of the electric wire changes and a gap is created between the wire harness and the bottom wall and both side walls, the vibration causes interference between the wire harness, the bottom wall, both side walls, and the cover, resulting in abnormal noise. May occur.

また、ワイヤーハーネスがプロテクタ内で分岐して幹線部と分岐線部とに分岐する部分をプロテクタで保護するような場合において、幹線部では蓋材によってワイヤーハーネスを押さえ付けて、その振動を抑制することができても、分岐線部では電線の本数が分岐により少なくなっているので、この部分が小径となり、分岐線部で底壁部、両側壁部、蓋材との間に隙間が生じて、振動により異音が発生するおそれがある。 In addition, when the wire harness branches in the protector and protects the main branch part and the branch line part with the protector, the trunk part suppresses the vibration by pressing the wire harness with a lid. Even if it is possible, since the number of wires in the branch line portion is reduced due to branching, this part has a small diameter, and there is a gap between the bottom wall portion, both side wall portions, and the lid material in the branch wire portion. There is a risk that abnormal noise may occur due to vibration.

このような場合、ワイヤーハーネスの径に応じてプロテクタ本体の底壁部、両側壁部、蓋材で囲まれる内部の断面積を設定したプロテクタをそれぞれ形成することによりワイヤーハーネスと底壁部、両側壁部、蓋材との間に隙間が生じないようにすることが考えられる。しかしながら、この場合には、プロテクタを成形する金型をワイヤーハーネスの径の種類に応じて複数個設けることになり、金型の種類が多くなる。 In such a case, the wire harness and the bottom wall part, both sides are formed by forming the protector with the cross-sectional area set inside surrounded by the bottom wall part, both side wall parts, and the cover material of the protector body according to the diameter of the wire harness. It is conceivable that no gap is generated between the wall portion and the lid. However, in this case, a plurality of molds for molding the protector are provided according to the type of diameter of the wire harness, and the types of molds are increased.

そこで、本発明はワイヤーハーネスの径が変化しても、ワイヤーハーネスの径に応じたプロテクタを形成することなく、ワイヤーハーネスをプロテクタ本体内に確実に固定することができるプロテクタを提供することを目的とする。 Then, even if the diameter of a wire harness changes, this invention aims at providing the protector which can fix a wire harness in a protector main body reliably, without forming the protector according to the diameter of a wire harness.
