Embodiment Construction

[0029] It can be seen from the background art that the optical fiber connector in the prior art has the problem of limited transmission laser power. Combining with the optical fiber connector in the prior art, the reasons for the limitation of the transmitted laser power are analyzed:

[0030] refer to figure 1 , shows a schematic cross-sectional structure diagram of an optical fiber joint.

[0031] The optical fiber connector includes a housing 10 and a sleeve 12 inside the housing 10 for fixing the optical fiber 11 ; the sleeve 12 is sleeved on the end of the optical fiber 11 . In the prior art, the material of the sleeve 12 is generally metal, which is directly wrapped on the end surface of the optical fiber 11 .

[0032] When the optical fiber connector is in use, laser light is coupled into the optical fiber 11 , and the laser light is totally reflected on the surface of the optical fiber 11 , thereby realizing the propagation of the laser light in the optical fiber 11 ...

Abstract

The invention relates to an optical fiber connector, which comprises a shell with a hollow through hole, a sleeve and a protective element, and is characterized in that an optical fiber penetrates through the hollow through hole; the sleeve is located in the hollow through hole and used for fixing the optical fiber; and the protective element is located between the optical fiber and the sleeve and used for realizing heat dissipation. According to the invention, heat dissipation is realized through setting the protective element between the end part of the optical fiber and the sleeve, the heat dissipation capacity of the end part of the optical fiber is improved, and the possibility that the tube wall temperature of the sleeve is enabled to rise because light leak at the end part of the optical fiber is reduced, thereby being conducive to reducing burnout of the optical fiber due to too high temperature of the sleeve, and facilitating to improve the power of laser transmitted in the optical fiber.

Description

technical field [0001] The invention relates to an optical fiber passive device, in particular to an optical fiber joint. Background technique [0002] Laser is one of the great inventions of mankind in the 20th century, and it is widely used in many fields. The clinical value of low-intensity laser irradiation therapy has been affirmed at home and abroad. Mainly used in the treatment of brain diseases, cardiovascular diseases, diabetes, malignant tumors, leukemia, psychiatric diseases, psoriasis, rhinitis and other diseases. According to the discovery of health medicine, low-intensity laser has a good curative effect in the early prevention of cardiovascular and cerebrovascular diseases and the recovery period after the onset, and has a certain effect on health and inhibition of human aging. In addition, laser technology is also widely used in biochemical testing, blood analysis, etc., and high-power lasers can also be used in surgical operations. [0003] In surgery, th...
