specific Embodiment 1

[0049] The double-core plug of the present invention is used for inserting and matching with the adapter in the front and back direction, so as to realize the connection transmission of the optical fiber signal.

[0050] In this example, if image 3 , Figure 4 , Figure 7 , Figure 9 and Figure 10 As shown, the double-core plug includes a plug housing assembly 4 and an optical fiber extending into the plug housing assembly 4. The plug housing assembly 4 includes an inner housing 40 and an outer housing 41, and the inner housing 40 is fixed with a plug inner housing. There are two plug-in cores, and the optical fiber extends into the inner housing 40 from the rear end and is connected to the rear end of the corresponding plug-in inner core, so as to realize the connection between the optical fiber and the plug housing assembly 4 . The front end of the plug-in inner core is exposed from the front end of the inner housing 40 to form a plug-in end for plugging and mating wit...

specific Embodiment 2

[0069] The difference between it and the specific embodiment 1 is that there is only one plug-in position in the adapter housing adapted to the double-pin plug in this embodiment, that is, one adapter housing is mated with a double-pin plug, and the double-pin plug On the inner housing, the locking claw is arranged on the outer wall corresponding to the long side of the rectangular inner housing, and the corresponding hollow slot is arranged on the outer wall corresponding to the long side of the rectangular outer housing. The positions of the hollowed-out slots are corresponding.

specific Embodiment 3

[0071] The difference from the first embodiment is that only the upper side wall of the inner casing is provided with locking claws and elastic hooks, the lower side wall is not provided with locking claws and elastic hooks, and the locking elastics on the upper side wall The claws cooperate with the bayonet on the upper side of the adapter housing to realize the locking fit between the double-core plug and the adapter, and the resisting bosses and guiding protrusions on the adapter housing corresponding to the lower side wall of the inner housing are continuously arranged in the front and rear directions. That is, no bayonet is provided between the resisting boss on the lower side of the adapter housing and the guiding protrusion.

[0072] In other embodiments, only the locking claws and elastic hooks are provided on the lower side wall of the inner housing, and the upper side wall is not provided with locking claws and elastic hooks, which correspond to the upper side wall of...

Abstract

The invention relates to a double-core plug shell assembly and a double-core plug. The double-core plug comprises an inner shell and an outer shell, and the inner shell and the outer shell are detachably connected. A locking elastic claw is located on the outer side surface of the inner shell and overhangs from front to back; a bidirectional stop structure is arranged on the inner shell and is used for being in stop fit with the outer shell in the front direction and the rear direction; a hollow long groove is formed in the outer shell and corresponds to the locking elastic claw so that at least parts of the locking elastic claw is exposed out of the outer shell to be matched with a resisting boss of an adapter in a stopping manner; and a pressing structure is arranged on the outer shell and presses the locking elastic claw downwards in the process that the outer shell slides backwards relative to the inner shell so that the locking elastic claw is unlocked from the resisting boss of the adapter. According to the double-core plug, if the polarity of the double-core plug needs to be replaced, only the inner shell needs to be taken out of the outer shell, the posture of the inner shell is replaced, then the inner shell is installed into the outer shell again, polarity replacement is completed, operation is convenient, and installation is accurate.

Description

technical field [0001] The invention relates to the field of connectors, in particular to a double-core plug housing assembly and a double-core plug. Background technique [0002] With the rapid popularization of optical fiber communication technology, its application in industry and life is becoming more and more extensive, and the accompanying optical plug-in components, namely optical fiber connectors, have also been continuously developed. At present, more duplex LC connectors and their adapters are used, such as Figure 1-2 As shown, the duplex LC connector 2 includes a pair of LC plugs and a fixed housing for fixing the two LC plugs. The LC plug includes a shell and a claw 20 arranged on the outer surface of the shell. The middle sides of the claw 20 are A boss 21 is provided, and a pressing plate 22 cantilevered to the upper side of the claws 20 of the paired LC plugs is provided on the fixed clamping shell. A card stand 10 is provided in the insertion cavity of the ...
