Description

光纖轉接器Fiber optic adapter

本創作係有關一種光纖轉接器，更特別有關一種單件式光纖轉接器。This creation is about a fiber optic adapter, more specifically a single-piece fiber optic adapter.

近年來，用於通信目的的光纖使用量已經非常大，數據、語音和其他通信網路越來越多使用光纖來傳輸信息。光纖通常配置為用來承載光的玻璃纖維。單根纖維可以被分組成能夠同時攜帶大量數據。In recent years, the amount of fiber used for communication purposes has been very large, and data, voice, and other communication networks are increasingly using optical fibers to transmit information. Optical fibers are typically configured as fiberglass for carrying light. Individual fibers can be grouped to carry large amounts of data at the same time.

在建構光纖網路時，每根光纖通常會連接到來源設備和目標設備。另外，沿著來源和目的地之間的光纖路徑，可以在光纖上形成各種連接或耦合以調整光纖長度。每個連接或耦合需要連接器和轉接器來對齊光纖，使得光可以不中斷地傳輸。典型的連接器包括兩個對稱的殼體，每個殼體具有連接器閂鎖。一個對齊袖管(sleeve)放置在連接器閂鎖內，以確保光纖精確地對齊。然後，兩個殼體以焊接（即，通過超音波焊接）、鉚接或其他方式彼此附接在一起，從而形成連接。然後將單根光纖放置在每個連接器閂鎖內，對齊袖管因此對齊了光纖。When building a fabric, each fiber is typically connected to the source and destination devices. Additionally, along the fiber path between the source and destination, various connections or couplings can be formed on the fiber to adjust the fiber length. Each connection or coupling requires a connector and an adapter to align the fibers so that light can be transmitted without interruption. A typical connector includes two symmetrical housings, each housing having a connector latch. An aligned sleeve is placed inside the connector latch to ensure precise alignment of the fibers. The two housings are then attached to each other by welding (ie, by ultrasonic welding), riveting or other means to form a joint. A single fiber is then placed in each connector latch, aligning the sleeves and thus aligning the fibers.

由於需要多個部件（每個部件可能需要單獨製造），並且必須進行焊接、鉚接或其他連接工藝來連接兩個對稱的殼體，所以這種示例性的連接器生產成本較高。此外，由於在焊接過程中兩個對稱的殼體部件可能移位，所以對齊問題可能由連接過程引起。This exemplary connector is costly to produce because multiple components are required (each component may need to be manufactured separately) and must be welded, riveted or otherwise joined to join the two symmetrical housings. Furthermore, since two symmetrical shell parts may be displaced during the welding process, the alignment problem may be caused by the joining process.

在1994年5月31日授予Beard等人的美國專利第5,317,663號公開了一種減少所需部件數量的方法。在前述專利中，公開了一種光纖轉接器，該光纖轉接器包括了放置兩個連接器閂鎖的單件式外殼以及對齊袖管。然而，為了將部件放置在殼體內，在殼體中設有窗口，並將一個外蓋焊接在外殼上以覆蓋該窗口。雖然前述美國專利的設計可以消除由於連接兩個殼體部件而導致的任何對齊問題，但是仍然需要許多部件和多個組裝步驟，包括將殼體罩蓋焊接在窗口上。A method of reducing the number of components required is disclosed in U.S. Patent No. 5,317,663, issued to A.S. Pat. In the aforementioned patent, an optical fiber adapter is disclosed that includes a one-piece housing with two connector latches and an aligned sleeve. However, in order to place the component within the housing, a window is provided in the housing and an outer cover is welded to the housing to cover the window. While the design of the aforementioned U.S. patent can eliminate any alignment problems caused by joining the two housing components, many components and multiple assembly steps are still required, including welding the housing cover to the window.

另外，如圖1所示，一種習知LC雙工型光纖轉接器包含有一外殼體100、一對齊袖管(sleeve)300以及一內殼體200。In addition, as shown in FIG. 1, a conventional LC duplex fiber optic adapter includes an outer casing 100, an aligned sleeve 300, and an inner casing 200.

請參照圖2，外殼體100內部具有左、右兩個結構相同的腔室190。腔室190由四個壁圍繞形成，其內部設置有一底板110以及一對齊圓筒130。底板110大致上為矩形，其兩側分別連接到腔室190的左壁與右壁，而另外兩側則分別靠近腔室190的上壁和下壁，但並未與腔室190上壁和下壁連接。對齊圓筒130從底板110延伸出。外殼體100內部還形成有兩個楔形的擋塊140，分別設置在腔室190的上壁與下壁上。各楔形擋塊140具有一正面141以及一卡扣面142。Referring to FIG. 2, the outer casing 100 has two chambers 190 having the same structure, left and right. The chamber 190 is formed by four walls, and a bottom plate 110 and an alignment cylinder 130 are disposed inside. The bottom plate 110 is substantially rectangular, and its two sides are respectively connected to the left and right walls of the chamber 190, and the other two sides are respectively close to the upper and lower walls of the chamber 190, but not to the upper wall of the chamber 190 and The lower wall is connected. The alignment cylinder 130 extends from the bottom plate 110. The inside of the outer casing 100 is further formed with two wedge-shaped stoppers 140 which are respectively disposed on the upper wall and the lower wall of the chamber 190. Each wedge stop 140 has a front surface 141 and a snap surface 142.

請參照圖3，內殼體200包含有一底板210，該底板210的正面延伸出有一對齊圓筒230，該對齊圓筒230的前後兩端各具有一開口，其中後端開口係開設在底板210上。底板210背面的兩側邊各延伸出有一卡勾240，該兩卡勾240係相對設置，且各卡勾240包含有一第一延伸部241、一第二延伸部242以及一卡扣部243，其中第一延伸部241與第二延伸部242大致上形成一個V字形的剖面。Referring to FIG. 3, the inner casing 200 includes a bottom plate 210. The front surface of the bottom plate 210 defines an alignment cylinder 230. The front and rear ends of the alignment cylinder 230 have an opening. The rear end opening is defined by the bottom plate 210. on. A hooks 240 are disposed on the two sides of the back surface of the bottom plate 210. The two hooks 240 are oppositely disposed, and each of the hooks 240 includes a first extending portion 241, a second extending portion 242, and a latching portion 243. The first extension portion 241 and the second extension portion 242 form a substantially V-shaped cross section.

前述光纖轉接器在組裝時，係將對齊袖管300的一半從對齊圓筒130後端***對齊圓筒130內。之後，將內殼體200塞入外殼體100的腔室190內，並使對齊袖管300的另一半從對齊圓筒230後端***對齊圓筒230內。圖4顯示前述組裝完成後的光纖轉接器。The aforementioned fiber optic adapter is assembled by inserting one half of the aligned sleeve 300 from the rear end of the alignment cylinder 130 into the alignment cylinder 130. Thereafter, the inner casing 200 is inserted into the chamber 190 of the outer casing 100, and the other half of the aligned sleeve 300 is inserted into the alignment cylinder 230 from the rear end of the alignment cylinder 230. Figure 4 shows the fiber optic adapter after the aforementioned assembly is completed.

當前述內殼體200組裝至定位後，其卡扣部243會抵在擋塊140的卡扣面142上，藉此防止內殼體200拉出外殼體100外。除此之外，第一延伸部241與第二延伸部242會被壓縮並***底板110與腔室190上壁和下壁之間的空隙內。When the inner casing 200 is assembled to the positioning, the locking portion 243 abuts against the locking surface 142 of the stopper 140, thereby preventing the inner casing 200 from being pulled out of the outer casing 100. In addition to this, the first extension portion 241 and the second extension portion 242 are compressed and inserted into the gap between the bottom plate 110 and the upper and lower walls of the chamber 190.

前述內殼體200組裝至定位後，因第一延伸部241與第二延伸部242被嚴重壓縮，兩者間的連接處因此產生巨大的應力，時間久後卡勾240的作用容易失效。After the inner casing 200 is assembled to the position, since the first extending portion 241 and the second extending portion 242 are severely compressed, the joint between the two is greatly stressed, and the action of the hook 240 is prone to failure after a long time.
