Abstract
Provided is a polarization-maintaining insertion core heater, comprising an upper support, a lower support, an electric heating block, and a countershaft heating block. The heater is characterized in that the countershaft heating block is fixed on the electric heating block which is embedded with a heating wire on the center. The countershaft heating block is provided with insertion core holes, and the insertion core holes are in a groove. The insertion core holes are vertical to a plane in the groove. The countershaft heating block of the polarization-maintaining insertion core heater is provided with the insertion core holes, the insertion core holes are in the groove, and the insertion core holes are vertical to the plane in the groove. Internal grooves are directly used to make an insertion core step horizontal, and horizontal accuracy is greatly improved, thereby improving error-tolerant rate. The polarization-maintaining insertion core heater is characterized by high production efficiency and high horizontal accuracy rate of the insertion core step.
Description
Technical field
The utility model relates to optical fiber industry, specifically refers to a kind of inclined to one side lock pin well heater of protecting.
Background technology
The inclined to one side lock pin of guarantor of prior art adopts the step of outside notch water plug flat core to axle heat block, horizontal accuracy rate and the production efficiency of lock pin step are not high, cause serious forgiveness low.
Summary of the invention
The utility model object is to propose the inclined to one side lock pin well heater of a kind of production efficiency guarantor high, that the horizontal accuracy rate of lock pin step is high.
The technical solution of the utility model is: the inclined to one side lock pin well heater of guarantor of the present utility model, it comprises upper bracket, lower carriage, electric heating block and to axle heat block, in the middle of it is characterized in that axle heat block to be fixed on, inlay on the electric heating block of heating wire, to there being lock pin hole on axle heat block, above-mentioned lock pin hole is in a groove, and above-mentioned lock pin hole is vertical with the plane in groove.
The inclined to one side lock pin well heater of guarantor of the present utility model, due to there being lock pin hole on axle heat block, above-mentioned lock pin hole is in a groove, and above-mentioned lock pin hole is vertical with the plane in groove.Directly adopt inner notch water plug flat core step, the accuracy rate of level is greatly improved, thereby has improved serious forgiveness.The utlity model has production efficiency high, the feature that the horizontal accuracy rate of lock pin step is high.
