Description

本発明は、電子制御装置のワイヤハーネス保護構造に関する。   The present invention relates to a wire harness protection structure for an electronic control device.

しかし、特許文献１に記載の発明では、金型により突出部の樹脂成形を行う場合、金型の型抜きにより底面に開口部が形成され、この開口部の縁部が鋭利に形成される。このため、振動等によってワイヤハーネスが開口部の縁部に接触した場合、ワイヤハーネスの一点に大きな圧力が作用し、このような接触の繰り返しによりワイヤハーネスに被覆された絶縁材が損傷する可能性がある。   However, in the invention described in Patent Document 1, when the protrusion is resin-molded by a mold, an opening is formed on the bottom surface by die cutting of the mold, and the edge of the opening is sharply formed. For this reason, when the wire harness comes into contact with the edge of the opening due to vibration or the like, a large pressure acts on one point of the wire harness, and the insulation covered with the wire harness may be damaged due to repeated such contact. There is.

本発明は、振動等によってワイヤハーネスが開口部の縁部に繰り返し接触した場合であっても、ワイヤハーネスに被覆された絶縁材の損傷を防止し、ワイヤハーネスを保護することができる電子制御装置のワイヤハーネス保護構造を提供することを目的とする。   The present invention relates to an electronic control device capable of preventing damage to an insulating material covered with a wire harness and protecting the wire harness even when the wire harness repeatedly contacts the edge of the opening due to vibration or the like. An object of the present invention is to provide a wire harness protection structure.

本発明は、開口部の縁部のうち突出部の突出方向に延びる部分に、突出方向から見てワイヤハーネス側へ向けて張り出す弧状の保護部を形成したことを特徴とする。 The present invention is characterized in that an arc-shaped protection portion that protrudes toward the wire harness side when viewed from the protruding direction is formed in a portion extending in the protruding direction of the protruding portion in the edge portion of the opening.

本発明によれば、開口部の縁部のうち突出部の突出方向に延びる部分に、突出方向から見てワイヤハーネス側へ向けて張り出す弧状の保護部を形成したことから、ワイヤハーネスが開口部の縁部に接触した場合であっても、保護部によりワイヤハーネスに作用する圧力が分散される。このため、ワイヤハーネスの一点に大きな圧力が作用することがなくなり、開口部の縁部との接触の繰り返しによりワイヤハーネスに被覆された絶縁材が損傷することが防止され、ワイヤハーネスを保護することができる。   According to the present invention, since the arc-shaped protection portion that protrudes toward the wire harness side when viewed from the protruding direction is formed in the portion of the edge portion of the opening portion that extends in the protruding direction of the protruding portion, the wire harness is opened. Even when it contacts the edge of the part, the pressure acting on the wire harness is dispersed by the protective part. For this reason, a large pressure does not act on one point of the wire harness, and the insulating material covered by the wire harness is prevented from being damaged due to repeated contact with the edge of the opening, thereby protecting the wire harness. Can do.

以下、本発明の実施形態について説明する。
図１に示すように、本実施形態に係る電子制御装置１は、例えばハイブリッド車等の車両の走行用のモータを制御するパワーコントロールユニット（ＰＣＵ）に内蔵されている。ＰＣＵは、車両のバッテリの電圧を昇圧し、交流に変換してモータに電力を供給する。 Hereinafter, embodiments of the present invention will be described.
As shown in FIG. 1, an electronic control device 1 according to this embodiment is built in a power control unit (PCU) that controls a motor for driving a vehicle such as a hybrid vehicle. The PCU boosts the voltage of the vehicle battery, converts it into alternating current, and supplies power to the motor.

ＰＣＵは、モータを制御する図示しないモータＥＣＵと、ＩＰＭ５と、常時放電抵抗７と、急速放電抵抗９と、電子制御装置１と、を含んで構成されている。
ＩＰＭ５は、モータＥＣＵへの給電経路の電圧を昇圧するものである。
常時放電抵抗７及び急速放電抵抗９は、モータＥＣＵへの給電経路の電流を調整するものである。
電子制御装置１は、ワイヤハーネス１１と、基板３と、筐体４と、を含んで構成されている。
ワイヤハーネス１１は、電線を絶縁材で被覆して構成され、ＩＰＭ５と、常時放電抵抗７と、急速放電抵抗９と、に接続されると共に、基板３に接続されている。
基板３は、各種電子部品を実装されると共にワイヤハーネス１１に接続され、ワイヤハーネス１１を介して、ＩＰＭ５と、常時放電抵抗７と、急速放電抵抗９と、の間で電力を授受する。
筐体４は、樹脂成形により形成され、ワイヤハーネス１１及び基板３が組み込まれている。 The PCU includes a motor ECU (not shown) that controls the motor, an IPM 5, a constant discharge resistor 7, a rapid discharge resistor 9, and the electronic control unit 1.
The IPM 5 boosts the voltage of the power supply path to the motor ECU.
The constant discharge resistor 7 and the rapid discharge resistor 9 adjust the current in the power supply path to the motor ECU.
The electronic control device 1 includes a wire harness 11, a substrate 3, and a housing 4.
The wire harness 11 is configured by covering an electric wire with an insulating material, and is connected to the IPM 5, the constant discharge resistor 7, and the rapid discharge resistor 9 and is connected to the substrate 3.
The substrate 3 is mounted with various electronic components and connected to the wire harness 11, and exchanges electric power among the IPM 5, the constant discharge resistor 7, and the rapid discharge resistor 9 through the wire harness 11.
The housing 4 is formed by resin molding, and the wire harness 11 and the substrate 3 are incorporated therein.

図２，３に示すように、筐体４は、底面１６と、底面１６に立設されて互いに対向する立設面１７，１８と、立設面１７から突出する突出部１９と、を含んで構成されている。   As shown in FIGS. 2 and 3, the housing 4 includes a bottom surface 16, standing surfaces 17 and 18 that are erected on the bottom surface 16 and face each other, and a protruding portion 19 that protrudes from the erected surface 17. It consists of

これにより、車両に振動等が発生した場合であっても、底面１６と、立設面１７，１８と、突出部１９と、によって、ワイヤハーネス１１の配線位置が規制される。   Thereby, even when vibration or the like occurs in the vehicle, the wiring position of the wire harness 11 is regulated by the bottom surface 16, the standing surfaces 17 and 18, and the protruding portion 19.

また、底面１６における突出部１９と対向する位置に、開口部２１が形成されている。開口部２１は、突出部１９を金型で樹脂成形する際に、金型の型抜きによって形成される。 In addition, an opening 21 is formed at a position on the bottom surface 16 that faces the protrusion 19. The opening 21 is formed by die cutting when the protrusion 19 is resin-molded with a mold.

開口部２１の縁部２３のうち突出部１９の突出方向に延びる部分に、該突出方向から見て、ワイヤハーネス１１側へ向けて張り出す弧状の保護部２３ａが形成されている。
これにより、車両に振動等に起因してワイヤハーネス１１が縁部２３に接触した場合であっても、弧状の保護部２３ａによりワイヤハーネス１１に作用する圧力が分散されるため、縁部２３がワイヤハーネス１１の一点に対して大きな圧力を作用させることが回避される。このため、ワイヤハーネス１１が縁部２３に繰り返し接触した場合であっても、ワイヤハーネス１１に被覆された絶縁材の損傷が防止され、ワイヤハーネス１１を保護することができる。 An arc-shaped protection portion 23 a that protrudes toward the wire harness 11 when viewed from the protruding direction is formed in a portion of the edge portion 23 of the opening 21 that extends in the protruding direction of the protruding portion 19.
Thereby, even when the wire harness 11 contacts the edge portion 23 due to vibration or the like in the vehicle, the pressure acting on the wire harness 11 is dispersed by the arc-shaped protection portion 23a. Applying a large pressure to one point of the wire harness 11 is avoided. For this reason, even if it is a case where the wire harness 11 contacts the edge part 23 repeatedly, damage to the insulating material coat | covered with the wire harness 11 is prevented, and the wire harness 11 can be protected.

なお、弧状の保護部２３ａは、開口部２１の縁部２３をその周辺よりも凸状とすることで形成するのみならず、縁部２３に対し面取りを行うことで形成してもよい。   In addition, the arc-shaped protection part 23a may be formed not only by making the edge part 23 of the opening part 21 convex from the periphery but also by chamfering the edge part 23.

本発明は、振動等に起因してワイヤハーネスが筐体に接触した場合に、ワイヤハーネスを保護する電子制御装置のワイヤハーネス保護構造を提供することにある。   An object of the present invention is to provide a wire harness protection structure for an electronic control device that protects a wire harness when the wire harness comes into contact with a housing due to vibration or the like.
