可视压接状态的光纤活动连接器

Abstract

本实用新型公开了一种可视压接状态的光纤活动连接器，包括连接器外壳、尾部套管和外壳后套，外壳后套上装配有铆压支撑环和铆压束环，尾部套管上设有可视窗口，可视窗口用于观察铆压支撑环与外壳后套、铆压束环与铆压支撑环的铆压连接状态；通过可视窗口可以观察压接处部件是否有脱落，如未观察到铆压束环、铆压支撑环脱落，可以直接判定在光缆的施工拉线过程中没有对其与光纤活动连接器的连接产生损伤，可以进行正常的连接使用；如观察到铆压束环或铆压支撑环脱落分离，则说明光纤与光纤活动连接器的连接处有受损，需要进一步检查并实施复接，以保证光缆在安装连接后能够顺利地使用，直接保证了光纤的连接质量，并间接保证了光纤的连接效率。

Claims

1. A fiber optic field connector with visual crimp status, comprising a connector housing for housing internal components, a tail ferrule removably assembled with said connector housing, an end of said connector housing housing a housing backshell connected to said tail ferrule, and said housing backshell extending partially outside of said connector housing, a crimp support ring for introducing an optical fiber removably assembled with said housing backshell outside of said connector housing, and a crimp band ring assembled with said crimp support ring, characterized in that: The tail sleeve is provided with a viewing window corresponding to the position of the riveting support ring and the riveting clamping ring. The viewing window is used to observe the riveting connection status between the riveting support ring and the rear sleeve of the outer shell, and between the riveting clamping ring and the riveting support ring. The outer shell is fitted with a riveting enhancement device at the connection point with the riveting support ring. The outer wall of the riveting support ring is provided with a riveting positioning mark, and the riveting positioning mark is set corresponding to the riveting enhancement device. The viewing window includes a window through-hole that runs through the tail tube. A viewing window plate is fixed on the tail tube to cover the window through-hole. The viewing window plate is transparent and also serves as a protective cover for the window through-hole.

2. The visual crimp status fiber optic field connector of claim 1, wherein: the crimp status indicator is a color; and the crimp status indicator is visible through the crimp status indicator window. The riveting enhancement device includes at least one riveting enhancement ring groove disposed on the outer wall of the rear sleeve of the housing.

3. The visual crimp status fiber optic field connector of claim 2, wherein: the crimping of the ferrule into the crimping groove is visible through the window. The riveting positioning mark is a riveting positioning coating set on the outer wall of the riveting support ring, and the riveting positioning coating is an annular structure corresponding to the riveting enhancement ring groove. The riveting positioning coating and the riveting enhancement ring groove are set one-to-one, and the color of the riveting positioning coating is different from the color of the tail sleeve. ​ 4. The visual crimp status fiber optic field connector of claims 2 or 3, wherein: The riveting enhancement groove is configured as an arc groove, and the two sides are smoothly transitioned to the outer wall of the rear sleeve of the outer shell using an arc surface.

5. The visual crimp status fiber optic field connector of claim 1, wherein: the crimp status indicator is a color; and the crimp status indicator is visible through the outer housing. The connector housing is configured as either the housing of an SC type fiber optic active connector or the housing of an FC type fiber optic active connector.
