Embodiment 1

[0092] Embodiment 1 of the optical fiber connector in the present invention: the optical fiber connector in this embodiment is used to connect LC-type optical fibers, and can meet the requirement of fast on-site wiring of LC-type optical fibers. Such as figure 1 and figure 2 As shown, the optical fiber connector mainly includes a front housing 17, a ferrule assembly and a tail wiring assembly, and the tail wiring assembly includes a main housing 10, a fiber protection sliding sleeve 12 and an optical cable fixing member 11, which constitute the components of the optical fiber connector. There are many, so the structure of each part of the fiber optic connector is now explained.

[0093] The main housing 10 in the tail wiring assembly is installed on the rear end of the front housing 17 when assembling the optical fiber connector, and is assembled with the front housing 17 to form a shell, and the two sides of the main housing 10 are provided with triangular main housings bu...

Embodiment 2

[0112]Embodiment 2 of the optical fiber connector in the present invention: the difference from the above embodiments is that in this embodiment, the fiber protection sliding sleeve is inserted into the optical cable fixing part, and the wall surface that cooperates with the fiber protection sliding sleeve in the optical cable fixing part The rubber strip or frosted surface is set on the top, and the friction between the fiber protection sliding sleeve and the rubber strip or the frosted surface is relatively large, which can realize the sliding resistance cooperation between the fiber protection sliding sleeve and the optical cable fixing piece in the direction of the insertion sleeve, and make the optical fiber from the When stretching out from the fiber protection sliding sleeve, the operator needs to apply force to overcome the frictional force between the fiber protection sliding sleeve and the optical cable fixing member, so that the fiber protecting sliding sleeve protrud...

Embodiment 3

[0113] Embodiment 3 of the optical fiber connector in the present invention: the difference from the above-mentioned embodiments is that the maximum contour size of the fiber protection sliding sleeve in this embodiment is larger than the maximum contour size of the optical cable fixing part, and the optical cable fixing part is inserted into the in the slide. A slide block is arranged on the outer surface of the optical cable fixing part, and a guide groove is arranged on the inner wall surface of the fiber protection sliding sleeve, and the sliding block is embedded in the guide groove so that the optical cable fixing part and the fiber protection sliding sleeve can guide and cooperate. In other embodiments, the cross-sections of the fiber protection sliding sleeve and the cable fixing member are both rectangular or circular, relying on the inner and outer surfaces of the fiber protection sliding sleeve and the optical cable fixing member to achieve guiding fit between the fi...

Abstract

The invention provides an optical fiber connector and a tail wiring assembly thereof, and can solve the problems that an optical fiber is easily scratched and damaged with the inner wall of an existing optical fiber connector during assembly, and the reliability and the percent of pass are low due to the fact that optical signal transmission is affected by chippings generated by scratching. The tail wiring assembly comprises a main shell and an optical cable fixing piece; a fiber protection sliding sleeve is assembled with the optical cable fixing piece in an inserting and sleeving manner; thefiber protection sliding sleeve is provided with an extension position and a retraction position relative to the optical cable fixing piece; when in the extending position, the optical fiber fixing piece and the optical cable fixing piece jointly enclose a fiber protection space; when in the retraction position, the optical fiber can extend out of the front end of the optical fiber protection sliding sleeve; the fiber protection sliding sleeve and the optical cable fixing piece are in sliding resistance fit in the direction of a plug bush so as to keep relative fixation when no external forceis applied to the two; a stop structure is arranged in the inner cavity of the main shell and can be matched with the front end of the fiber protection sliding sleeve in an abutting mode to enable the fiber protection sliding sleeve to overcome the sliding resistance acting force with the optical cable fixing piece to retract; and the main shell is also provided with an opening for the optical fiber to extend out of the main shell.

Description

technical field [0001] The invention relates to an optical fiber connector and a tail wiring assembly thereof. Background technique [0002] The scheme of using optical fiber to transmit optical signals is widely used and mature, and because the positions of the two modules connected by optical fiber are uncertain, technicians arrange the optical fiber on site according to the distance between the two modules, and then connect the optical fiber connector with the The optical fiber is assembled and connected, and finally the optical fiber connector is inserted into the module. Existing optical fiber connectors are formed by nesting and combining multiple parts. For example, an optical cable connector disclosed in a patent document with the authorized announcement number CN207851354U and the authorized announcement date of 2018.09.11 includes a single butt joint housing. The front cover and the simplex back cover, and the ferrule assembly installed in the housing, the ferrule...
