Description

Technical Field

[0001] The utility model relates to a connector device for optical fiber connection, in particular to an anti-loosening connector device for optical fiber connection. Background Art

[0002] The control system data of the mobile device is transmitted through the optical fiber line, and the optical fiber line is connected through the optical fiber connector. The general optical fiber connector adopts the plug-in type and the screw-in type connection method. Due to the vibration generated during the operation of the mobile device, the general optical fiber connector of the plug-in type and the screw-in type is generally loosened or detached after being subjected to the vibration for a long time during the long-term operation of the mobile device. Once the optical fiber connector is loosened or detached, the data of the mobile device is disconnected and out of control, which affects the operation of the mobile device or causes a production accident, resulting in a large economic and safety loss. In view of the above reasons, an anti-loosening connector device for optical fiber connection is proposed. Utility Model Content

[0003] The purpose of the utility model is to overcome the vibration generated during the operation of the mobile device. During the long-term operation of the mobile device, the plug-in type and the screw-in type of the general optical fiber connector will become loose or detached after being subjected to vibration for a long time. Once the optical fiber connector becomes loose or detached, the data of the mobile device will be disconnected or out of control, which will affect the operation of the mobile device or cause a production accident. Through reasonable design, an anti-loosening connector device for optical fiber connection is provided. The anti-loosening connector device of the utility model pushes the nut limiting disk through the anti-loosening spring sleeve to prevent the locking nut from rotating and loosening. The nut limiting disk is combined with the locking nut surface through the elastic friction force, which can prevent the locking nut from loosening and rotating. In addition, when the gap between the nut limiting disk and the locking nut is large, the locking nut can be prevented from loosening by combining the anti-loosening limiting block with the anti-loosening limiting groove. The phenomenon of loosening or detaching of the optical fiber connector can be avoided, so as to ensure the normal communication and control of the mobile and transported equipment, the smooth data transmission of the optical fiber line, and extend the service life of the communication and control system of the mobile and transported equipment.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-loosening connector device for optical fiber connection, which is composed of: an optical cable threading sleeve, an anti-loosening spring sleeve, an anti-loosening limit block, a spring, a nut limit disk, a locking nut, an anti-loosening limit groove, a socket positioning sleeve, a connector body, a spring seat, an optical fiber core sleeve, and a socket; an optical cable threading sleeve is arranged at the rear end of the anti-vibration loosening connector device, a socket positioning sleeve is arranged at the front end of the anti-vibration loosening connector device, a connector body is arranged between the optical cable threading sleeve and the socket positioning sleeve, an anti-loosening spring sleeve is arranged on the outside of the connector body, and a spring is arranged between the connector body and the anti-loosening spring sleeve; a nut limit disk is arranged at one end of the anti-loosening spring sleeve, and an anti-loosening limit block is arranged on one side of the nut limit disk; a spring seat is arranged on the outside of the rear end of the connector body, and both ends of the spring are arranged corresponding to the spring seat and the nut limit disk respectively;

[0005] An optical fiber core sleeve is arranged at the rear end of the connector body, and an optical fiber core is arranged in the optical fiber core sleeve; a socket is arranged at the front end of the connector body, a socket positioning sleeve is arranged at the outside of the socket, and a matching connector plug is arranged in the socket and the socket positioning sleeve; a locking nut is arranged at the outside of the socket positioning sleeve; a locking thread is arranged between the socket positioning sleeve and the locking nut; an anti-loosening limit groove is reserved at one end of the locking nut corresponding to the nut limit disk, and an anti-loosening limit block is arranged in the anti-loosening limit groove.

[0006] Beneficial effects: The anti-loosening connector device of the utility model pushes the nut limit plate through the anti-loosening spring sleeve to prevent the locking nut from loosening due to rotation. The nut limit plate is combined with the locking nut surface through elastic friction, which can prevent the locking nut from loosening and rotating. In addition, when the gap between the nut limit plate and the locking nut is large, the locking nut can be prevented from loosening by combining the anti-loosening limit block with the anti-loosening limit groove. The phenomenon of loosening or detachment of the optical fiber connector can be avoided, ensuring normal communication and control of mobile and transported equipment, smooth data transmission of the optical fiber line, and extending the service life of the communication and control systems of mobile and transported equipment.
