Heating groove assembly for optical fiber fusion splicer

Abstract

The invention discloses a heating groove assembly for an optical fiber fusion splicer, and relates to the technical field of optical fiber fusion splicing. The heating groove assembly for the opticalfiber fusion splicer comprises a circuit substrate and two heating elements connected in a V shape, a V-shaped groove serves as a heating area, a thermal shrinkable sleeve provided with an optical fiber fusion point is arranged in the heating area, and the included angle of the V shape is about 40 degrees; the bottom of each heating element is connected with a concave pin penetrating through the circuit substrate, the inner wall of each heating element is coated with an anti-sticking layer, the outer wall of each heating element is pasted with a rectangular resistance layer, the boundary of each resistance layer is smaller than that of the corresponding heating element, and an electrode layer is pasted on each concave pin. A V-shaped supporting plate is arranged between the circuit substrate and the heating element and is tightly attached to the outer wall of the heating element, the attaching position of the supporting plate and the heating element is in an arc shape, and the fillet radius of the arc is smaller than 1 mm; during use, the contact area with the heat-shrinkable sleeve is increased, the heat conduction speed is increased, and the heating efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of optical fiber fusion splicing, in particular to a heating tank assembly for an optical fiber fusion splicing machine. Background technique [0002] Optical fiber joint fusion usually includes two main processes: fusion and heat shrinkage. The fusion splicing process includes advancement, core adjustment, and discharge. If the surface becomes fragile, it is necessary to wrap the welding point with a heat-shrinkable sleeve and put the heating tank assembly in the heat-shrinking device for heat-shrinking reinforcement. [0003] At present, most optical fiber fusion splicers use U-shaped tank heating tank components. On the one hand, there is only one line contact between the heat shrinkable tube and the tank body, so the heat conduction speed is slow and the heating efficiency is low; on the other hand, The pad that realizes the electrical connection between the heating element and the control circuit is in...

Problems solved by technology

[0003] At present, most optical fiber fusion splicers use U-shaped tank heating tank components. On the one hand, there is only one line contact between the heat shrinkable tube and the tank body, so the heat conduction speed is slow and the heating efficiency is low; on the other hand, The pad that realizes the electrical connection between the heating element and the control circuit is in the core high temperature area, which will inevitably cause the temperature of the pad to be too high, and the temperature of the pad that is too high will cause the lead wire to be separated from the pad, and the pad to be separated from the base of the heating element, eventually causing heating. fail
