Fiber optic connector

#This application claims priority of Taiwanese Utility Model Patent Application No. 110207743, filed on Jul. 2, 2021.

#The disclosure relates to a connector, more particularly to a fiber optic connector.

#With continuous advancement of data transmission technology, new specifications, such as a four-channel quad small form-factor pluggable (QSFP) interface, for optical fiber connectors of high speed optical fibers are developed. Referring to FIGS. 1 and 2, a conventional optical fiber connector 1 includes a casing body 11, a head sleeve 12 disposed in the casing body 11, two core heads 13 mounted between the casing body 11 and the head sleeve 12 and arranged vertically spaced apart from each other, a tail sleeve 14 connected removably to a rear end of the casing body 11, a handling lever 15 disposed on the casing body 11 and extending rearwardly, and two engaging members 16 extending from the casing body 11 upwardly. When it is desired to connect the optical fiber connector 1 to an adaptor or a socket (not shown), the casing body 11 is inserted into the adapter or the socket, and at least one of the engaging members 16 is engaged into a slot formed in the adaptor or the socket, such that the core heads are connected with another two core heads (not shown) inserted into the adaptor or the socket, respectively. By use of various pairing modes of the core heads 13, a change in polarity of connection can be achieved.

#Other features and advantages of the disclosure will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:

#FIG. 1 is a schematic side view of a conventional optical fiber connector;

#FIG. 2 is an exploded perspective view illustrating the structure of the conventional optical fiber connector shown in FIG. 1;

#Referring to FIGS. 3 to 5, an embodiment of a fiber optic connector according to the present disclosure is shown. The fiber optic connector includes a ferrule 2, an insert body 3 detachably inserted into the ferrule 2, a tail sleeve 4 sleeved on a rear end of the insert body 3 along a front-rear direction (A), and two core heads 5 extending removably into a front end of said ferrule 2 and spaced apart from each other along an up-down direction (C) transverse to the front-rear direction (A).

#The ferrule 2 includes an outer frame 21, an operating handle 22 extending rearwardly from the outer frame 21 along the front-rear direction (A), and two engaging members 23 (only one is visible) protruding from the outer frame 21 along the up-down direction (C) away from each other and adapted to be connected to an adaptor. The outer frame 21 of the ferrule 2 includes a front frame portion 211, two lateral frame portions 212 connected to the front frame portion 211, extending along the front-rear direction (A), and spaced apart from each other along a left-right direction (B) transverse to the front-rear direction (A) and the up-down direction (C), and two connecting wall portions 213 (only one is visible) spaced apart from each other along the up-down direction (C) and connected to the lateral frame portions 212. The front frame portion 211 surrounds and defines an inserted opening 214 that is open along the front-rear direction (A). Each of the lateral frame portions 212 is formed with a limiting slot 215 open along the left-right direction (B). Each of the connecting wall portions 213 is formed with a sliding slot 216 that extends along the front-rear direction (A) and open rearwardly. The operating handle 22 is integrally connected to the lateral frame portions 212 and one of the connecting wall portions 213, and is formed with a slot 221 extending along the front-rear direction (A), open forwardly, and in spatial communication with the sliding slot 216 of the corresponding one of the connecting wall portions 213 to constitute a slot unit. The engaging members 23 protrude respectively from the connecting wall portions 213 of the outer frame 21 away from each other, i.e., one of the engaging members 23 protrudes upwardly and the other one of the engaging members protrudes downwardly.

#Further referring to FIG. 6, the insert body 3 is disposed in the outer frame 21, and includes a casing sleeve 31 permitting the core heads 5 to extend thereinto, a receiving seat 32 connected to a rear end of the casing sleeve 31, and a plurality of polarity-representing marks 33.
