Rotary self-locking SC type optical cable connector and assembly structure thereof

Abstract

The invention provides a rotary self-locking SC type optical cable connector and an assembly structure thereof. A mortise provided with a tail handle as well as a spring and a locking seat are arranged between an SC inner frame and an SC rotary outer frame of the connector, a rotary pull rod, a loudspeaker ring and a circular ring are arranged between the SC rotary outer frame and a tail sleeve, and an optical cable is connected from the tail sleeve; an inclined boss and a raised column are arranged at the top of the SC inner frame, and arc-shaped holes matched with an arc-shaped fixture blockon the locking seat are formed in the two side walls of the rear end of the SC inner frame; a first groove matched with the raised column is formed in the top of the SC rotary outer frame, the frontend of the SC rotary outer frame is matched with the inclined boss, a second groove is formed in the rear end of the SC rotary outer frame, and a third groove is formed in the front end of the SC rotary outer frame; and a fixture block matched with the second groove is arranged at the front end of the rotary pull rod, and a handle is arranged at the rear end of the rotary pull rod. The rotary self-locking SC type optical cable connector provided by the invention locks an optical cable connector by virtue of a specific self-locking structure, the connector is prevented from being pulled out bymistake, connection reliability of the connector with an adapter is guaranteed, smooth network signal connection is guaranteed, and use safety of the connector is improved.

Description

technical field [0001] The invention relates to the technical field of an optical cable connector and its assembly structure, in particular to a rotary self-locking SC type optical cable connector and its assembly structure. Background technique [0002] With the rapid development of the optical communication industry, conventional optical jumpers, optical connectors and other products are widely used, especially conventional LC, SC, FC, ST and other optical cable connectors. In the application of FTTH fiber to the home, chassis, and optical modem, the demand for SC connectors has greatly increased. [0003] The existing SC-type optical cable connector is connected to the adapter with a bayonet structure. In the use of the data center chassis, the SC-type optical cable connector can be easily pulled out due to the setting of the bayonet structure. cause loss. Another example is that if the optical modem has been connected for a long time or has been accidentally pulled out...

Problems solved by technology

[0003] The existing SC-type optical cable connector is connected to the adapter with a bayonet structure. In the use of the data center chassis, the SC-type optical cable connector can be easily pulled out due to the setting of the bayonet structure. cause loss

Another example is that if the optical modem has been connected for a long time or has been accidentally pulled out, the SC type optical cable connector is easy to fall off, causing the end face of the connector to be dirty. , The dirt on the end face will seriously affect the network signal. At this time, repairs need to be performed by professionals. The maintenance and cause investigation will waste a lot of time and resources; , easy to cause accidental damage, this is because most of the lasers transmitted in the optical fiber are 1310nm or 1550nm wavelength lasers, and the light of this wavelength belongs to infrared light, which is invisible to the naked eye

Therefore, the existing SC-type optical cable connectors cannot effectively prevent accidental pulling out. After the connector falls off, the network signal will be affected due to the dirty end face, and the optical fiber head of the connector after falling off is easy to cause damage to the eyes.
