Problems solved by technology
[0002] The bare fiber on the existing fiber optic connector plug is directly exposed to the plug-in end of the fiber optic connector plug. During the process of carrying, using and maintaining, it is easy to touch the bare fiber, causing damage to the bare fiber. When the last bare fiber is inserted into the adapter, the signal loss transmitted by the optical fiber connector will increase or even the signal will be interrupted, which seriously affects the normal working stability and increases the maintenance cost.
[0003] When the optical fiber connector plugs at both ends of the existing multi-core optical fiber connector are inserted into the adapter, the bare fibers on the two optical fiber connector plugs are guaranteed by the cooperation of the guide pin and the guide hole. The guide hole and the guide pin will be worn out, which will lead to poor alignment accuracy, resulting in inaccurate centering of the ferrules at both ends after the two fiber optic connector plugs are inserted, resulting in interruption or instability of the communication signal, which will affect the normal adverse effect on communications

Embodiment Construction
[0030] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0031] exist figure 1 and figure 2 The fiber optic connector plug in the illustrated embodiment of the present invention includes a first body 10, and the first body 10 includes a plug-in end 11, and a longitudinal insertion hole for inserting an optical fiber end is provided on the plug-in end 11. One end of the optical fiber 20 protruding from the insertion end 11 is a row of a plurality of bare fibers 21 arranged in parallel at adjacent intervals. The bare fibers 121 are cantilevered in the longitudinal insertion hole, and will freely bend slightly in the longitudinal insertion hole under force. The fiber optic connector plug is also provided with a bare fiber protection device 30, which is installed on the plug en...

The invention relates to a connector of an optical fiber connector plug, the connector plug includes a plug-in end, and the plug-in end includes a longitudinal insertion hole for inserting an optical fiber end; the optical fiber connector plug also includes a bare fiber protection device and The elastic device; the bare fiber protection device includes a through hole corresponding to the longitudinal insertion hole for the bare fiber at the end of the optical fiber to pass through, and can move back and forth between a protection position and a working position in the longitudinal direction of the insertion end Installed on the plug-in end; the elastic device is arranged between the bare fiber protection device and the plug-in end, providing an elastic force for the bare fiber protection device to maintain the protection position. Through the bare fiber protection device in the present invention, the bare fiber can be isolated and protected from the outside when the optical fiber connector plug is in a non-working state, and will not be damaged by external force impact.
Description
technical field [0001] The invention relates to an optical fiber connector, more specifically, to a multi-core optical fiber connector plug and a multi-core optical fiber connector. Background technique [0002] The bare fiber on the existing fiber optic connector plug is directly exposed to the plug-in end of the fiber optic connector plug. During the process of carrying, using and maintaining, it is easy to touch the bare fiber, causing damage to the bare fiber. When the final bare fiber is inserted into the adapter, the signal loss transmitted by the optical fiber connector will increase or even the signal will be interrupted, which seriously affects the normal working stability and increases the maintenance cost. [0003] When the optical fiber connector plugs at both ends of the existing multi-core optical fiber connector are inserted into the adapter, the bare fibers on the two optical fiber connector plugs are guaranteed by the cooperation of the guide pin and the gui...
