Abstract
一种光纤耦合器,一耦合座、与该耦合座相对两端分别配合的至少一 镜套及至少一耦合头、固设该镜套内的至少一镜片,其特征在于:该光纤 耦合器还包括调整镜套与耦合头之间的相对位置的至少一第一固定件及至 少一第二固定件,其中第一固定件与镜套松动配合,并与耦合座紧密配合; 第二固定件与镜套紧密配合,并与耦合座抵接配合。本实用新型光纤耦合 器通过第二固定件与镜套之间紧密配合后,再装有镜片的镜套移动来调整 镜片的焦点的轴向位置,调节好后,该第二固定件可防止镜套发生相对滑 移,再通过第一固定件将镜套固定在耦合座上,稳定性较好,调节距离统 一,且本整体结构简单,成本低,节省调节时间。

Abstract (en)
An optical fiber coupler includes a coupling supporter, at least a lens bag and at least a coupling head which respectively match with both ends of the coupling supporter which are opposite to each other, and at least a lens which is fixed in the lens bag; the utility model is characterized in that the optical fiber coupler also includes at least a first fixture and at least a second fixture which are used to adjust the relative positions of the lens bag and the coupling head, wherein, the first fixture loosely matches with the lens bag and tightly matches with the coupling supporter; the second fixture tightly matches with the lens bag, and rejects to and matches with the coupling supporter. The optical fiber coupler of the utility model adjusts the axial positions of the focus of the lens by shifting the lens bag with the lens after the second fixture and the lens bag tightly match; after adjustment, the second fixture can prevent the lens bag from relatively sliding; and then the first fixture fixes the lens bag on the coupling supporter, so that the stability is quite good and the adjusted distance is unified; in addition, the integral structure has simple structure, is low in cost and saves the adjusting time. |
