Embodiment Construction

[0018] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Specific embodiments of the fiber optic connector plug of the present invention, such as figure 1 As shown, the fiber optic connector plug includes a fiber optic connector plug housing and an optical cable 5 that is worn and fixed in the fiber optic connector plug housing. The fiber optic connector plug housing includes a front housing 1, and a The locking sleeve 2 and the rear sleeve 3 sleeved on the rear end of the front housing 1 .

[0020] The front housing 1 is provided with a mounting hole for a ferrule component. There is a fixed section with a larger diameter in the middle of the ferrule component mounting hole. The ferrule component includes a ceramic pin 11 and a flange 12 sleeved behind the ceramic pin 11. The rear outer side of the flange plate 12 is provided with a fastening sleeve 13 with a step at the front end, the outer side of t...

Abstract

The invention relates to an optical fiber connector plug shell and an optical fiber connector plug. The fiber optic connector plug housing includes: a front housing, in which ferrule components are installed; a rear sleeve, which is connected to the rear end of the front housing and encloses an inner cavity with the front housing, and the rear sleeve has an optical cable passage, and the rear sleeve An optical cable sheath fixing structure is also provided in the sleeve; the optical cable sheath fixing structure includes a crimping sleeve and a supporting sleeve, and the crimping sleeve can be placed outside the supporting sleeve to press the optical cable sheath on the supporting sleeve. In the present invention, the sheath of the optical cable is sleeved on the supporting sleeve from the rear and then crimped through the crimping sleeve. When applying glue, since the inner side of the sheath of the optical cable has a support pad, the glue is difficult to flow into the inner sheath of the optical cable, and the optical fiber can be The retraction is carried out in the outer sheath of the optical cable, so the plug housing does not need to be provided with a remaining section for the bending of the optical fiber, thereby reducing the length of the entire plug housing, so that the plug using this plug housing can be installed in a place where the space is relatively narrow , with a wider scope of application.

Description

technical field [0001] The invention relates to an optical fiber connector plug shell and an optical fiber connector plug. Background technique [0002] Optical fiber connector is a device for connecting optical fibers to optical fibers, and is used to precisely butt the end faces of two optical fibers. The Chinese invention patent application with the application publication number CN109445040A discloses a YMF series circular optical fiber connector. The plug of the connector includes a housing. The inner sleeve of the sheath and the crimping sleeve set outside the crimping sleeve, the outer sheath of the optical cable is crimped and fixed by crimping the sleeve after the front end of the inner sleeve is folded over to the outside of the inner sleeve. In order to improve the tensile strength of the optical fiber connector plug, it is also necessary to apply glue to the crimping part. In the actual glue application process, first apply glue to the torn optical cable sheath ...
