Description

Technical Field

[0001] The utility model relates to the technical field of optical cable jumpers, and more specifically to an adjustable glue dispensing fixture for optical cable jumpers. Background Art

[0002] One of the processes in the assembly of optical modules is to connect the fiber jumper to the PCB integrated module. There are usually two connection methods: one is plug connection and the other is glue connection. The plug connection is convenient for disassembly, storage and transportation. However, among the many types of modules, some modules still need to adopt the second connection method. In this way, the module assembly requires the use of a fixture to complete the glue process.

[0004] However, the aforementioned patent has the following drawbacks: the internal cavity of the PCB fixing slot is fixed in size, which means that optical cable jumpers can only be installed on PCBs of a specific size, making it impractical. Furthermore, after the optical cable jumper is fixed to the jumper holder, it is difficult to adjust the front-to-back position and vertical height of the optical cable jumper, making it difficult to align the glue joints between the optical cable jumper and the PCB. Therefore, we propose an adjustable glue dispensing fixture for optical cable jumpers. Utility Model Content
