Description

Technical Field

[0001] The utility model relates to the technical field of circuit board production and processing, in particular to a crimping jig for optical fiber connectors. Background Art

[0002] Fiber optic connectors are devices that make detachable (movable) connections between optical fibers. They precisely connect the two end faces of optical fibers so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent possible, and the impact on the system caused by its involvement in the optical link is minimized. This is the basic requirement of fiber optic connectors. To a certain extent, fiber optic connectors affect the reliability and performance of optical transmission systems.

[0003] The crimping of optical fiber connectors requires a more convenient and faster method, so we proposed a crimping jig for optical fiber connectors to solve this problem.

The crimping jig includes an upper mold and a lower mold for pressing an aluminum sleeve and a beam ring; the upper mold and the lower mold are combined to form a crimping mold cavity; the crimping mold cavity is a through hole, and the through hole includes a stepped table surface, the large hole portion on one side of the stepped table surface is the aluminum sleeve crimping hole, and the small hole portion on the other side of the stepped table surface is the beam ring crimping hole.
