Embodiment Construction
[0027] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0028] Specific embodiments of the optical fiber connector of the present invention, such as Figure 1 to Figure 2 As shown, the optical fiber connector includes an optical fiber connector housing and an optical cable 5 that is fixed in the optical fiber connector housing. The optical fiber connector housing includes a front housing 1 and a locking sleeve 2 sleeved on the outside of the front housing 1. And the rear sleeve 3 that is screwed on the rear end of the front housing 1.
[0029] A ferrule component mounting hole is provided in the front housing 1, and the ferrule component is fixed in the ferrule component mounting hole. A locking sleeve 2 is provided on the outside of the front housing 1. After the locking sleeve 2 is screwed and fitted with the socket, the front housing 1 is pressed forward, so that the ferrule parts inside the front housing...

The invention relates to an optical fiber connector shell and an optical fiber connector. The optical fiber connector shell comprises a front shell, a rear sleeve and a sheath; an insertion core partis mounted in the front shell; an optical cable outer skin fixed structure is arranged in the rear shell; the sheath is inserted at the tail part of the rear sleeve; a step structure of which the front side has a large diameter and the rear side has a small diameter is arranged outside the sheath; a large-diameter section is closely attached to the inner wall of the rear sleeve, and a small-diameter section extends out of the rear sleeve; the rear sleeve extends backwards to form an engaging lug; pressure plates are fixed on the engaging lug; two pressure plates clamp the sheath together; andthe pressure plates are in checking fit with the step surface on the sheath in the axial direction of the sheath. The optical fiber connector shell carries out fixing by enabling the rear sleeve to extend backwards to form the engaging lug and enabling the pressure plates to clamp the sheath, and thus, a case of driving the sheath to rotate so as to drive an optical cable to rotate cannot be generated; and when the tail part of the optical fiber connector is fixed, the optical fiber connector shell is easier to enable the optical cable and an optical fiber to be kept in a normal flat and straight state, so that reliability of the optical fiber connector is improved.
Description
technical field [0001] The invention relates to an optical fiber connector housing and an optical fiber connector. 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. A sealing ring and a compression ring are arranged in the tail sleeve of the connector. Tighten, seal with the optical cable, and at the same time press the compression ring axially forward through the sealing nut, and the compression ring compresses the sealing ring to fix the tail. However, in the actual operation process, when the sealing nut is rotated, as the sealing nut, the compression ring and the sealing ring are gradually compressed, it is easy to cause the sealing nut to drive the compression ring and the sealing ring to ro...
