Description

本発明は、冷却ファンの取付構造に関し、特に電源リード線の余長引き回しに関する。 The present invention relates to a mounting structure of a cooling fan, to extra length routing of particular power leads.

冷却ファン装置を備えた機器の従来構造の一例を、以下に示す。 An example of a conventional structure of a device equipped with a cooling fan device, shown below.

冷却ファン装置は、ファン穴が形成された対向する第1の面と第2の面を有する直方形状の外装体を有し、その内部に冷却ファンを備える。 Cooling fan device has a exterior body of rectangular shape having a first surface and a second surface opposite the fan holes are formed, a cooling fan therein. また、第2の面からは冷却ファン装置を駆動するための電源リード線が引き出されており、側面(第1の面と第2の面をつなぐ面)には、第1の面から第2の面へと溝形状が形成される。 Further, from the second surface is led power leads to drive the cooling fan device, the side surfaces (first surface and a surface connecting the second surface) is first from the first surface 2 groove shape is formed into a plane.

冷却ファン装置の取付対象である機器については、その筐体において冷却ファン装置が設置されるための開口穴、および開口穴の奥の角部には冷却ファン装置を固定させるためのねじ穴が形成された保持具が形成される。 The cooling fan device apparatus is a mounting target, opening holes for the housing thereof a cooling fan apparatus is installed, and the corner portion of the back of the opening hole screw holes for fixing the cooling fan device formed retention device is formed. 筐体内部には、冷却ファン装置の電源リード線と接続されるためのコネクターが設置される。 Inside the housing, a connector for being connected to a power lead of the cooling fan apparatus is installed.

冷却ファン装置は、第1の面が機器の保持具側を向くように、筐体の開口穴に設置される。 Cooling fan device, the first surface so as to face the retainer side of the device, is placed in an opening hole of the casing. このとき、電源リード線は冷却ファン装置の第2の面から側面に形成された溝形状を通って第1の面側へと引き回され、さらに筐体の内部に配置されているコネクターに接続される。 At this time, the power supply leads are routed to the first surface through a formed on the side surface of the second surface of the cooling fan device groove shape, connected to the connector being further arranged inside the housing It is.

このような構成において、電源リード線は冷却ファン装置を設置する前に開口穴を介してコネクターと接続される為、余長をもって形成される。 In such a configuration, the power supply leads to be connected with the connector through the opening hole before installing the cooling fan device, is formed with a surplus length. 従って、冷却ファン装置とコネクターとの間の狭い空間で配線処理しなければならない。 It must therefore be wire treated with a narrow space between the cooling fan unit and connector. このとき、電源リード線の余長は組付状態においてたるみとなり、余長部分が移動したり吸い込まれて、冷却ファンの羽根に接触して破損することがある。 At this time, the excess length of the power leads become slack in assembled state, the extra length portion is drawn or moved, it may be damaged in contact with the blades of the cooling fan.

これに対し、冷却ファン装置における電源リード線の余長処置に関するものが、特許文献1に示されている。 In contrast, it relates to the extra length treatment of power leads in the cooling fan unit is shown in Patent Document 1. 特許文献1では、冷却ファン装置の取付対象である制御装置について、冷却ファン装置の取り付け面に密着すると共にファン穴が形成された仕切り部材と、冷却ファン装置の位置を決める位置決め部材を有し、仕切り部材と位置決め部材との間に空隙が形成され、そこから電源リード線を引き出す構成となっている。 Patent Document 1, for an attachment object of the cooling fan device controller includes a partition member which is fan holes formed with close contact with the mounting surface of the cooling fan device, a positioning member for positioning of the cooling fan device, gap between the partition member and the positioning member is formed, has a configuration to bring out the power leads from there. 仕切部材によって電源リード線と冷却ファン装置の羽根との接触が阻止される。 Contact blades of the cooling fan unit and power lead by the partition member is prevented.

しかし、特許文献1の構成においても、例えば電源リード線接続用のコネクターが、取付対象における冷却ファン装置に近い通風路に形成されているような場合は、冷却ファン装置の近くの狭い空間で配線処理しなければならない。 However, in the configuration of Patent Document 1, for example, connectors for power lead connection, if such is formed in the ventilation path close to the cooling fan device in a mounting object, the wiring near the narrow space of the cooling fan device It must be processed. このとき、電源リード線の余長は組付状態においてたるみとなり、余長部分が移動したり吸い込まれて、冷却ファン装置の羽根に接触して破損することがある。 At this time, the excess length of the power leads become slack in assembled state, the extra length portion is drawn or moved, it may be damaged in contact with the blades of the cooling fan device.

この発明は上記の様な問題点を解消するために成されたもので、冷却ファン装置の取り付け時に電源リード線の余長の処置を容易に行うことができ、電源リード線が冷却ファン装置の羽根で破損することを防止できる冷却ファン取付構造を得ることを目的とする。 This invention has been made in order to solve such problems described above, the cooling fan device extra length treatment of power leads during mounting can be easily performed in the power supply leads of the cooling fan device and to obtain a cooling fan mounting structure it can be prevented from being damaged by the blade.

本発明は、冷却ファン装置を取付対象の保持具に取り付ける冷却ファンの取付構造に関する。 The present invention relates to a mounting structure of a cooling fan mounting the cooling fan device attached target holder. 冷却ファン装置は、保持具側を向く第1の面、その反対側の第2の面、溝形状が第1の面から第2の面へと形成された側面を備える。 Cooling fan device comprises a first surface facing the holder side, a second surface opposite the side where the groove shape is formed from the first surface to the second surface. また、冷却ファン装置の第2の面に対面して配設される、ファン穴を有する取付板を備え、冷却ファン装置は、第2の面において取付板との間に空間を形成する凹形状を備える。 Also, it is arranged facing the second surface of the cooling fan device, comprising a mounting plate having a fan holes, the cooling fan device, concave shape to form a space between the mounting plate in the second plane equipped with a. 冷却ファン装置の電源リード線は、冷却ファン装置の第2の面側から側面の溝形状を通って第1の面側へと引き回され、その余長は第2の面の凹形状内に収納可能である。 Power leads of the cooling fan unit, cooling from the second surface side of the fan unit through the groove shape of the side surface routed to the first surface side, the excess length in the concave inside of the second surface it can be stored.

冷却ファンの電源リード線を溝形状に引き廻した後、電源リード線のたるみを冷却ファン装置の凹形状に収納することにより、たるみが取付対象の筐体内部で発生しないので、電源リード線が冷却ファン装置の羽根に接触し破損することを防止することが可能である。 After the power leads of the cooling fan turn pulls the groove shape, by accommodating slack in the power leads to the concave shape of the cooling fan device, since slack is not generated inside the casing of the mounting object, the power supply leads it is possible to prevent the contact with the blades of the cooling fan device damage.
