Description

[0002] Against the backdrop of the nation's efforts to develop new productive forces and its announcement of a strategy to "develop humanoid robots with the full force of the nation," the construction of 10-gigabit fiber optic trunking (FTTR) networks by telecom operators is in full swing. While FTTR customers bring substantial cloud and computing network service fees, it also brings a sharp increase in maintenance pressure and costs for optical network operators, especially since FTTR uses fiber optic composite cables, which pose even greater challenges to connectivity.

[0003] The fiber optic composite cable connection device with fusion protection is generally used in conjunction with the main structure of the fusion splice protection base and the fiber optic splice, and becomes a component of the fusion splice box or fiber optic splice. Generally, the fiber optic composite cable consists of an outer sheath, positive and negative wires (multi-strand copper wires), a tight-closing layer, and bare optical fibers. The optical path connection is completed by cold splicing or hot fusion of two bare optical fibers, while the conduction and fixation of the positive and negative wires are accomplished by the fiber optic composite cable connection device with fusion protection.

[0004] Currently, there are no fiber optic composite cable connection devices with fuse protection on the market. Summary of the Invention

[0041] The beneficial effects of this utility model are:

[0042] 1. This utility model incorporates a fuse in the positive electrode circuit to achieve overcurrent protection. 2.

The diode illuminates when energized, and the presence of light through the card holder indicates whether the conductive connection is successful. This method is highly efficient and practical. 3. This utility model features a retaining ring and a clamp on the left and right positive electrode plates. The retaining ring holds the fuse securely, and the clamp holds or welds the electrode wires at both ends of the fuse, thus fixing the fuse and achieving circuit connection. The structure is compact, firmly fixed, and shock and drop resistant. 4. The left, right, and negative electrode plates extend to the contact slots on the optical cable base. They connect by "touching" with the conductive metal plate mounted on the optical cable base, solving the problem of connecting the fuse protection and power-on display components in a small space. The structure is simple and reliable. 5. The clip of this utility model can be removed from the optical cable holder, facilitating the replacement of the fuse and light-emitting component in the clip without affecting the connection of the optical circuit of the optoelectronic composite cable, thus simplifying maintenance. 6. The conductive metal plate installed in the guide groove of this utility model has corresponding clips on the base feet. By squeezing the base feet, the clips can be pre-cut into the outer sheath of the optoelectronic composite cable, reducing the risk of electric shock during operation. 7. With the threaded sleeve tightened, this utility model can shrink the space of the base feet, allowing the pressure teeth on the opposite sides of the base feet to embed into the outer sheath. This results in a more secure fixation of the optoelectronic composite cable, with a pull-out force greater than 50N. Simultaneously, the clips cutting into the outer sheath of the optoelectronic composite cable will not loosen or cause loose circuit connections. Attached Figure Description
