The application relates to the technical field of optical fiber manufacturing equipment, and discloses a fusion splicer for optical fiber manufacturing, which comprises a fusion splicer body, the upper surface of the fusion splicer body is fixedly connected with a guide mechanism, the upper surface of the fusion splicer body is clamped with a protective shell, the upper surface of the fusion splicer body is fixedly connected with a melting device and a clamping device, and the side surface of the fusion splicer body is fixedly connected with a damping mechanism. Through the setting of a semicircular cylinder, extrusion of the two semicircular heat-shrinkable tubes is realized, the two semicircular heat-shrinkable tubes are tightly attached, and the fusion joint is completely sealed; the two air bags flexibly clamp the optical fiber, rigid damage is avoided, the optical fiber is clamped with the heating box one by the semicircular heat-shrinkable tube two, and the external force influence on the fusion joint is reduced; the synchronous bending rod connects the two side push plates, synchronous movement is ensured, and the optical fiber is prevented from being unevenly stressed; the rough surface plate is rubbed with the fuselage, the sliding rod one is damped to slide, the speed of the optical fiber when moving above the heating box one is prevented from being too large, and the impact is reduced.

The utility model discloses a horizontal optical cable splicing box, including box body, box cover and fusion fiber tray, the rear side of box cover and box body hinge, and be provided with support column and fixed column in the box body, fusion fiber tray is provided with multiple groups, and the rear side of multiple fusion fiber trays is hinged in proper order, and the lowermost fusion fiber tray is set up on the support column, and is connected with the fixed column, and the uppermost fusion fiber tray cover is equipped with the apron, is provided with a plurality of fusion joint slot on the fusion fiber tray, and the inner wall distribution of fusion fiber tray is provided with a plurality of card position, and the top cover of adjacent fusion fiber tray is equipped with the baffle, when multiple fusion fiber trays are stacked, can be bound by the ribbon. The utility model discloses horizontal optical cable splicing box, through the hinge between box cover and box body, and the hinge between multiple fusion joint trays, can be convenient for the fusion of optical fiber, the coiling of optical fiber redundancy and wiring operation, and through multiple fusion joint trays can fuse more optical fiber, to improve the core number, and through the baffle and ribbon can ensure the fusion stability in multiple fusion joint trays.

This invention discloses an intermediate fusion joint for power cables, an integration method, and an online monitoring system. The joint comprises a conductor fusion connection portion, an insulation regeneration layer, and a metal shielding sleeve. The conductor fusion connection portion forms a fusion connection at the junction of two cable cores. The insulation regeneration layer covers the outside of the conductor fusion connection portion and includes a semi-conductive inner shielding portion, an insulating portion, and an outer shielding portion arranged sequentially from the inside out. The metal shielding sleeve covers the outside of the insulation regeneration layer, forming electromagnetic shielding and, together with the outer shielding portion, constituting the shielding structure of the joint area. This allows for the integrated restoration of conductor connection, electric field control, and shielding continuity in the joint area, ensuring stable electrical connection and insulation during long-term operation. This improves the withstand voltage stability and lifespan consistency of the intermediate joint under long-term load, temperature rise changes, and environmental fluctuations.

The utility model discloses a kind of PE yarn ultrasonic wire connecting device, including base, lifting adjusting mechanism, lifting seat, rotary table, double-shaft moving mechanism, ultrasonic welding head, cooling air pipe and wiring table;The movable end of rotary table is connected with double-shaft moving mechanism, ultrasonic welding head is located on double-shaft moving mechanism, wiring table is located on the base below ultrasonic welding head, wiring table top surface is equipped with wire clamping groove, wire clamping groove is used to place two PE yarns to be ultrasonically welded, cooling air pipe is obliquely arranged in the side end of the ultrasonic welding head.The ultrasonic welding head of the utility model can contact with the PE yarn in wire clamping groove, to make PE yarn end portion local melting by high-frequency vibration and adhere, wire clamping groove can limit two PE yarns and align, avoid PE yarn sliding or misplacement in welding process, after welding is completed, cooling air pipe can directional cooling to yarn fusion joint by cooling airflow, to shorten solidification time, improve wiring efficiency.
