Description

Technical Field

[0001] The utility model relates to the technical field of crimping clamps, and more specifically to a combined crimping clamp for optical cables. Background Art

[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communications cable assemblies that utilize one or more optical fibers enclosed in a sheath as the transmission medium and can be used individually or in groups. With the development of the optical communications industry, one or more lenses are placed at each end of an optical cable. The lenses, optical cables, crimping rings, and sleeves are combined to form an AOC optical module's optical cable jumper. The ends of the cable jumper are installed in two optical modules to form a module connection. During the processing of the cable jumper, the aluminum crimping sleeve needs to be crimped to connect the ceramic ferrule installed on the cable core to the cable sheath.

[0003] After searching, the utility model patent with announcement number CN210605089U discloses a multi-port synchronous crimping jumper clamp, including an upper clamp and a lower clamp cooperating with the upper clamp, and a plurality of crimping stations are correspondingly arranged between the upper clamp and the lower clamp, and a plurality of crimping interfaces of different specifications are arranged in any of the crimping stations; since the crimping interfaces of different sizes are made in the same crimping station, the aramid fiber and the outer skin of the optical cable can be directly crimped and fixed in place in one step at the same time, and the multiple crimping steps in the jumper production process can be omitted, and the risk factors of broken skin and different sizes in the crimping process are reduced, and the quality problems caused by secondary crimping are avoided, thereby greatly ensuring the quality of the jumper, reducing labor intensity, improving production efficiency, and reducing production costs; the patent also has the advantages of simple structure, reasonable design, convenient and accurate operation, etc.

[0004] However, the aforementioned patent has the following drawbacks: the fixture is not portable, making it inconvenient for patch cord manufacturing outdoors. Furthermore, it is difficult to support the ceramic ferrules and optical cables at both ends of the crimping sleeve. When the crimping sleeve is placed on the lower fixture, manual support is required to hold the ceramic ferrule and optical cable, making it inconvenient. Therefore, we propose a combined optical cable crimping fixture. Utility Model Content
