Optical fiber connector convenient for pipe penetration

Abstract

The utility model discloses an optical fiber connector convenient for pipe penetration. The optical fiber connector comprises a tail handle with a hollow through hole, an inner core and a tail sleeve, wherein the inner core and the tail sleeve surround the tail handle; the device further comprises a connecting piece and a traction piece. The connecting piece is sleeved on the tail handle, and one end of the connecting piece is connected with the tail sleeve; the inner core and the traction piece are detachably matched with the other end of the connecting piece in a replaceable mode. A rotatable traction part is arranged on the traction piece, a traction through hole penetrating through the traction part is formed in the traction part, and pipe penetrating is achieved through cooperation of a traction rope and the traction through hole; when the interior of the pipeline is uneven or the direction of a certain angle is changed, certain rotation acting force can be possibly generated to cause rotation when the traction rope is pulled to pull all the components to pass through, the traction part can relieve the rotation acting force through self rotation, and therefore the connecting piece, the tail handle, the tail sleeve and the optical fiber can pass through normally without rotation. And the risk that the optical fiber is damaged when penetrating through the tube is greatly reduced.

Description

It can permanently or detachably connect two optical fibers together and has a connecting part with protective components. Optical fiber connector is the end device of optical fiber.

[0003] In some construction environments, optical fibers need to pass through some pipelines, and optical fibers have very weak tolerance to lateral forces, and may be broken by a very small force; therefore, when optical fibers pass through some longer pipelines, if the optical fibers are directly inserted into the pipelines, they may be broken and damaged; of course, other objects can be used to bind the optical fibers and pull them through the pipelines, but the optical fibers may be damaged in the process of binding the optical fibers; to solve the above problems, a fiber optic connector is disclosed in the patent name of a fiber optic connector (application number CN202322848387.3), including a tail handle with a hollow through hole, a tail handle assembled on the tail handle to surround the tail handle An inner core and an outer shell assembled on the inner core, the outer shell cooperates with the optical fiber interface; the optical fiber enters the through hole and is connected to the tail handle; it also includes a traction member, which is detachably assembled on the inner core; after the traction member is removed from the inner core, the outer shell is assembled on the inner core and cooperates with the optical fiber interface; the inner core includes an assembly part that cooperates with the outer shell and the traction member; the traction member is provided with a traction part, and the traction part is provided with a traction perforation; the traction member is able to receive the traction force through the traction part and the traction perforation provided on the traction part, and then transmits the received force to the tail handle and the optical fiber, so as to drive the optical fiber through the pipeline without damaging the optical fiber as much as possible.
