Description of the Invention: [Technical Field] The present invention relates to a light pipe, and more particularly to a light guiding structure for preventing light wave interference. [Prior Art] Many electronic devices often use the signal light source emitted by the light emitting diodes (LED) as the indicator light of the current operating conditions of the electronic device, but the position of the light emitting diode is often set. It is separated from the surface of the casing of the electronic device, so the light pipe must be transmitted by means of a light pipe and displayed on the surface of the casing. Please refer to the schematic diagram of the configuration of the light pipe of the prior art. Each of the light emitting diodes 100 is disposed at one end of the light pipe 110 and emits light waves of red, blue, and green light of different wavelengths. When light waves are transmitted within the respective light pipes 110, the user can see the light being lit at the other end of the light pipe 110 to judge the current operation of the electronic device. > However, due to the limitation in forming, the light guide 110 must be plastically formed and connected by the fixed connecting member 120 so as to be fixed at an appropriate position inside the electronic device. However, this causes a light wave in the light pipe 110 to be conducted through the fixed connection member 120 to the other light pipe 1]0, resulting in a mixture of light waves and disordered optical signals. Therefore, how to make the light emitted from the light-emitting diode 100 not be conducted into the other light pipe 110 is an important issue that cannot be delayed. SUMMARY OF THE INVENTION The present invention provides a light guiding structure to prevent mutual interference of light wave phases 5 1306173 22652 twf.doc/g in a light pipe. The present invention provides a light guiding structure comprising a plurality of light pipes, a forming connector and a holder. The light pipes are arranged on a holder, and the light pipes are connected by a shaped connection. The shaped connector has a plurality of necked portions that can be broken to cause the shaped connectors to be disconnected from the light pipe. In an embodiment of the invention, a plurality of light emitting diodes are disposed at one end of each light pipe for emitting light waves into the light pipe, and the other end of the light pipe can display light waves transmitted through the light pipe as an indication. light. • In one embodiment of the invention, the mounting bracket includes a plurality of light blocking walls, and the light guides are spaced apart by the light blocking walls. In addition, the holder includes a plurality of hook members, and the light guide is fixed to the holder by a hook member. In one embodiment of the invention, the mount includes a plurality of plugs and the light guide is secured to the mount by a plug. In one embodiment of the invention, the necked portion is broken to intercept the transmission path of the light wave to prevent light waves from interfering with each other through the shaped joint between the two light pipes. φ The light guiding structure of the present invention can cut light waves through the forming connecting member by using the forming connecting member having the necking portion, so that the light wave transmission path can only be transmitted from the light introducing end of the light guide to the light guiding end, thereby avoiding light waves. Interfere with each other. The above described features and advantages of the present invention will become more apparent from the following description. [Embodiment] 6

请參考圖2之示意圖，成形連接件22〇具有多個 部222，其可破壞地連接光導管210。為了使成形連接部 220容易被移除，頸縮部222的截面積小於其他區域的戴 面積，例如約0.3mm ’因此使用者只要—次彎折成形連接 件220即可在頸縮部222斷裂而移除成形連接件22〇。如 圖3所示，經過組裝光導管21()之後，圖2的成形連接件 220被移除而不見於圖3中。 /當然，除了頸縮部222之外’亦可在成形連接件22〇 上形成多個截面積較小的區域，例如以鑽孔形成多個貫孔 (未繪示），以使貫孔周圍的結構強度被破壞而易於折斷 成形連接件220。 ' 、圖4為圖3之光導管固定在固定架上的剖面示意圖。 為了使各光導管210能緊固地固定在固定架23〇上，固定 ^ 230還設有多個插塞24〇以及多個卡勾件242、244。插 基240可插入光導管21〇的基座21〇a内，並且插塞240 可加熱施壓而使其融化固定於基座210a上。此外，卡勾件 242、244成對排列在光導管21〇兩侧。當外力施壓於光導 官210時，卡勾件242、244受力變形而使光導管21〇通過 8 1306173 22652twf.doc/g 其間並使光導官210固定於卡勾件242、244之下。由於各 光導官210可藉由上述的插塞240以及卡勾件242、244 固定於固定架230上，因此即使成形連接件22〇被移除， 仍不會影響其組裝可靠度。 π 所< 本發明之導光結構包括多個光導管、一成 形連接件固定架。成形連接件具有多 部，而 頸縮部可受;力斷裂而使志 '' 光波無法經由成形連光導管神^ 擋光牆，其配置於相;管：固定架還設=個 進而使相鄰光源之間不會相互影響。Μ防止先波干丈 限定本發施例揭露如上’然其龙非用以 脫離本發日月之精朴範二郝，巾具有通常知識者’在不 因此本發明之保護範圍 :^些許之更動與潤飾， 為準。 後附之申請專利範圍所界定者 【圖式簡單說明】 圖1是習知光導管的配詈_ ^ 9 Β , „ 日7配置不意圖。 圖3是是本發明—奋#彳丨九、〜構的示意圖。 圖4為圖3 ㈠之導光結構的配置示意圖 之切管固技㈣架上的剖面示意圖 【主要元件符號說明】 1 〇〇 •發光二極體 9 1306173 22652twf.doc/g 110 ： 光導管 120 ： 固定連接件 200 ： 導光結構 210 ： 光導管 210a :基座 212 ： 光導入端 214 ： 光導出端 220 ： 成形連接件 222 ： 頸縮部 230 ： 固定架 232 ： 擋光牆 240 ： 插塞 242、 244 :卡勾件 250 ： 基板 252 ： 隔板Referring to the schematic view of Fig. 2, the shaped connector 22 has a plurality of portions 222 that are detachably coupled to the light pipe 210. In order to facilitate the removal of the shaped connecting portion 220, the cross-sectional area of the necked portion 222 is smaller than the wearing area of other regions, for example, about 0.3 mm'. Therefore, the user can bend the necking portion 222 as long as the forming member 220 is bent. The shaped connector 22 is removed. As shown in Figure 3, the shaped connector 220 of Figure 2 is removed after assembly of the light pipe 21() and is not seen in Figure 3. / Of course, in addition to the necked portion 222, a plurality of regions having a small cross-sectional area may be formed on the formed connecting member 22, for example, a plurality of through holes (not shown) are formed by drilling to surround the through hole. The structural strength is broken to easily break the shaped connector 220. 4, FIG. 4 is a schematic cross-sectional view of the light pipe of FIG. 3 fixed on the fixing frame. In order to securely fix each of the light guides 210 to the holder 23, the fixing member 230 is further provided with a plurality of plugs 24A and a plurality of hook members 242, 244. The interposer 240 can be inserted into the base 21a of the light guide 21A, and the plug 240 can be heated and pressed to be fixed to the base 210a. Further, the hook members 242, 244 are arranged in pairs on both sides of the light guide 21''. When an external force is applied to the light guide 210, the hook members 242, 244 are deformed by force to cause the light guide 21 to pass through 8 1306173 22652 twf.doc/g and the light guide 210 is fixed under the hook members 242, 244. Since each of the light guides 210 can be fixed to the holder 230 by the above-described plug 240 and the hook members 242, 244, even if the formed joint 22 is removed, the assembly reliability is not affected. π < The light guiding structure of the present invention comprises a plurality of light pipes, a forming connector holder. The forming connector has a plurality of parts, and the neck portion can be subjected to; the force is broken, so that the light wave cannot be blocked by the light pipe, and is disposed in the phase; the tube: the fixing frame is further set to The adjacent light sources do not affect each other.
