Abstract

The utility model relates to an optical fiber flange for connect optic fibre, including base and drum, the drum is fixed on the base, be equipped with the through-hole on the drum, optic fibre alternates in the through-hole, be equipped with fixed area and inflation district in the through-hole, the fixed area with the inflation district is connected, and optic fibre is fixed in through the hot melt adhesive in the fixed area, the temperature risees, and the hot melt adhesive expands to the inflation district. The optical fiber flange can avoid the phenomenon that the optical fiber is broken by the expanded hot melt adhesive due to the expansion of the hot melt adhesive when the temperature rises, so that the optical fiber can stably transmit data.

Description

Optical fiber flange

Technical Field

The utility model belongs to the technical field of the information transmission technique and specifically relates to an optical fiber flange is related to.

Background

The optical cable is an optical fiber communication cable which takes optical fiber as a carrier and light wave as a transmission medium, the optical cable is mainly used in the communication industry, such as operators of telecommunication, mobile and Unicom, and the like, in addition, the broadcasting television field can also use the optical cable as the transmission medium of a broadcasting network, along with the large-area popularization of computers and smart phones, the information transmission amount is increased greatly, the traditional network line cannot be qualified for the existing workload, and the optical cable plays a leading role in information transmission.

In the optical fiber network physical connection in the prior art, the optical fiber movable connection depends on movable connectors at two ends, the middle part is fixedly butted with each other through an optical fiber connector, the flange is used as an important component part of the optical fiber connector, general optical fibers are fixed in the flange through hot melt adhesive, but when the temperature rises, the hot melt adhesive can expand, the optical fibers are easily broken, and the optical fibers cannot transmit data.

SUMMERY OF THE UTILITY MODEL

A primary object of the present invention is to provide an optical fiber flange, which can solve the above problems and prevent the thermal adhesive from expanding and breaking the optical fiber.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an optical fiber flange for connect optic fibre, including base and drum, the drum is fixed on the base, be equipped with the through-hole on the drum, optic fibre wears to be arranged in the through-hole, be equipped with fixed area and inflation district in the through-hole, the fixed area with the inflation district is connected, and optic fibre is fixed in through the hot melt adhesive in the fixed area, the temperature risees, and the hot melt adhesive is to the inflation district inflation.

Preferably, the expanded region has a diameter slightly larger than the fixation region.

Preferably, a guide area is arranged in the through hole, and the guide area is connected with the expansion area.

Preferably, a guide groove is arranged between the guide area and the expansion area.

Preferably, a groove is arranged on the base, and the groove is arranged on the outer surface of the base.

Preferably, the end of the fixing region is provided with a chamfer.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, an optical fiber flange is used for connecting an optical fiber, and includes a cylinder 1 and a base 2, the cylinder 1 is fixed on the base 2, the base 2 and the cylinder 1 are integrally formed, and can be directly processed on a lathe without assembly, thereby reducing production cost, a through hole 11 is provided on the cylinder 1, the optical fiber is arranged in the through hole 11, a fixing region 111, an expansion region 112 and a guiding region 113 are provided in the through hole 11, the fixing region 111, the expansion region 112 and the guiding region 113 are sequentially connected, the guiding region 113 can facilitate the optical fiber to be inserted into the through hole 11, the optical fiber is fixed in the fixing region 111 through hot melt adhesive, the temperature rises, the hot melt adhesive expands towards the expansion region 112, the diameter of the expansion region 112 is slightly larger than the fixing region 111, so that a space is left when the hot melt adhesive expands, thereby avoiding.

As a preferable scheme of this embodiment, a guide groove 12 is provided between the guide region 113 and the expansion region 112, and when the optical fiber is inserted, the guide groove 12 can guide the optical fiber into the expansion region 112, thereby facilitating the insertion of the optical fiber.

As a preferable scheme of this embodiment, the end of the fixing region 111 is provided with a first chamfer 13, and the end of the guiding region 113 is provided with a second chamfer 14, so as to protect the optical fiber and prevent the optical fiber from being broken when the optical fiber is in and out.

As a preferable mode of the present embodiment, the base 2 is provided with a groove 21, and the groove 21 is provided on the outer surface of the base 2, so that the flange can be fixed to the optical fiber connector.

The above-mentioned embodiments are merely preferred examples of the present invention, and do not limit the scope of the present invention, so all equivalent changes or modifications made by the structure, features and principles of the present invention should be included in the claims of the present invention.
