Pull ring unlocking structure of optical module

Abstract

The invention provides a pull ring unlocking structure of an optical module, which enables an upper cover and a sliding block to be integrated into an integrated structure, is quick and convenient to assemble, is good in subsequent reliability, and improves the production efficiency. The pull ring unlocking structure comprises an upper cover, a lower cover and a pull ring body, a first semi-cylindrical face and a second semi-cylindrical face which are equal in radius are arranged at the opposite positions of the rear ends of the upper cover and the lower cover, a transverse connecting rod of the pull ring body is embedded in a cylindrical mounting cavity formed by the first semi-cylindrical face and the second semi-cylindrical face, and swing arms on the two sides of the pull ring body are exposed. The pull ring unlocking structure is characterized in that a rear end mounting table is arranged at the rear end of the upper cover and used for mounting a pull ring, a notch groove is formed in the front end of the middle of the rear end mounting table in the width direction, a sliding block mounting groove is formed in the middle area of the lower surface of the rear end mounting table in the width direction, and a sliding block is embedded in the sliding block mounting groove; and a guide notch groove is formed in the front end of the middle of the sliding block in the width direction.

Description

technical field [0001] The invention relates to the technical field of optical communication technology, in particular to an unlocking structure of a pull ring of an optical module. Background technique [0002] When the optical module is in use, an elastic unlocking mechanism is usually used to realize the insertion and removal operation in the cage. When the optical module is inserted into the cage, the elastic unlocking mechanism rebounds and is fastened with the cage through the buckle; when the optical module is pulled out of the cage, the elastic unlocking mechanism pushes up the shrapnel on the cage to release the buckle. The existing elastic unlocking mechanism drives the slider and the spring that are lifted up by the shrapnel to be set independently. It is difficult to assemble, and the cooperation between the slider and the upper cover is difficult, and the parts are easy to be lost during assembly. As a result, the matching quantity of parts is inconsistent, whi...

Problems solved by technology

The existing elastic unlocking mechanism drives the slider and the spring that are lifted up by the shrapnel to be set independently. It is difficult to assemble, and the cooperation between the slider and the upper cover is difficult, and the parts are easy to be lost during assembly. It leads to inconsistent matching quantities of parts and components, which is not conducive to the improvement of production efficiency and mass production
