Abstract
The utility model relates to a manufacturing device used for optical fiber communication devices, particularly an electric heating device for the fusion of optical fiber communication devices. The utility model is characterized in that the utility model is formed by combining a high-temperature ceramic heat shielding protective sleeve 1 and an electrode 4. A groove 2 arranged on the protective sleeve 1 is matched with a groove 3 arranged on the electrode 4 to form a whole. Thus, the utility model can adjust the temperature in large range and exactly control the temperature, besides, the utility model can not be influenced by the external environment and has the advantages of stable heating and favorable consistency of performance of optical fibre devices. Furthermore, the utility model uses the low voltage for heating, which ensures high safety and reliability. The electric heating avoids OH<-> generation, reduces product consumption and raises product reliability.
Description
Technical field:
The utility model relates to a kind of fiber optic telecommunications equipment manufacturing installation, particularly fiber optic telecommunications equipment fused electric heater.
Background technology:
The fused biconical taper method is the important method of making fiber optic telecommunications equipment, and this method is the fiber fuse temperature more than 1100 ℃ that obtains by the burning high-purity gas, and there is following shortcoming in the method for this flame heating:
1. flame heating is subject to the interference of environment, waves easily, and the temperature instability causes the consistence of optical fibre device performance poor, and it also is subjected to the influence of jar interior gas pressure intensity in addition, need regulate the proportioning of two kinds of gases often, operation inconvenience.
2. the temperature regulating range of flame is narrow, reaches temperature required requirement, and the control difficulty is big.
3. flame heating produces [OH]
-, it is present in the loss that can cause optical fibre device in the optical fiber strengthens, and reduces reliability.
4. using gas is dangerous, and the price of gas is expensive, the preparation cost height.
Summary of the invention:
The purpose of this utility model is the weak point that overcomes aforesaid method, a kind of fiber optic telecommunications equipment fused electric heater that is applicable to is provided, can directly adopts electrically heated to come fused optic fiber in air, the consistency of performance of device be good, Technological Economy is good, satisfies the service requirements of opticfiber communication.
The utility model is used for the electric heater of optical fiber device fusion, and by pyroceramic thermal insulation protection cover 1 and electrode 4 combinations, the groove 3 that groove 2 and the electrode 4 that its protective sleeve 1 has has matches and is combined into an integral body.As shown in drawings.
The advantage and the positively effect of invention:
The utility model has overcome the existing shortcoming of flame heating, can regulate large-scale temperature, accurately temperature is controlled, and is not vulnerable to the influence of external environment, adds thermally-stabilisedly, and the consistency of performance of optical fibre device is good; The heating of employing low voltage, safe and reliable; [OH] avoided in electrically heated
-Produce, reduced the loss of product, improved reliability of products.
Description of drawings:
Fig. 1: the electricity that the utility model is used for optical fiber device fusion adds the device structural representation;
The side-view of Fig. 2: Fig. 1;
Fig. 3: electrode structure synoptic diagram;
The side-view of Fig. 4: Fig. 3.
Embodiment:
Fig. 1, Fig. 2 have showed that also the utility model is used for the working order of fiber optic telecommunications equipment fused electric heater; its energising rear electrode is to heating; temperature reaches more than 1100 ℃, the photoconductive fiber more than two is placed to make it fusion in the groove 3 that electrode 4 has and the groove 2 that the protective sleeve 1 that matches has be one.Realized the reallocation of luminous power in the optical fiber.
