Abstract

The utility model is an arc-bending fiber coupling arrangement designed particular for connecting the indoor fiber pigtail, comprising a fiber socket and a pigtail plug. The plug-in segment of the pigtail plug is arc bending, whose bending radius is 7.5-30mm; the angle between the plug-in segment and the pigtail sleeve is no less than 90 degree, but less than 120 degree; the optimum bending radius of the plug-in segment is 7.5mm and the optimum angle between the plug-in segment and the pigtail sleeve is 90 degree. The pigtail coupling arrangement is simple in structure, convenient in operation, little in the bending loss and good in the use effect is.

Description

A kind of tail optical fiber coupling arrangement

Technical field

The utility model relates to optical fiber communication, in particular to a kind of optical cable tail optical fiber coupling arrangement.

Background technology

In the communications field, optical fiber communication is widely used and develops, the application of optical cable in LAN (Local Area Network) is very extensive especially, various terminal devices all need to be connected with the optical cable tail optical fiber, because the geometrical property and the optical characteristics of optical fiber, and transport property has very high requirement to the tail optical fiber coupling arrangement, and existing tail optical fiber coupling arrangement is various informative, basically can satisfy request for utilization, but its tail optical fiber plug is linear pattern.Though can avoid the bending loss of optical fiber like this, to having relatively high expectations of environment for use and space, limitation is very big.

Summary of the invention

The utility model is exactly for solving a kind of circular arc elbow tail optical fiber coupling arrangement that its limitation designs, being made up of fiber-optical socket and tail optical fiber plug.The slotting body or the tail optical fiber sleeve pipe of tail optical fiber plug are circular shape, and the arc bend bilge radius is 7.5-30mm, and its slotting body and Pigtail sleeve pipe clamp angle are more than or equal to 90 °, less than 120 °.Insert body or Pigtail sleeve canal curvature radius and be preferably 7.5mm, insert body and Pigtail sleeve pipe clamp angle and be preferably 90 °.The utility model is crooked fixing in slotting body or tail optical fiber sleeve pipe with tail optical fiber, neither damages tail optical fiber, and it is still very convenient that tail optical fiber is pegged graft, and the requirement of usage space is reduced relatively, and do not increase the bending loss of optical fiber.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure, the slotting body of 1 tail optical fiber plug, 2 tail optical fiber sleeve pipes, 3 fiber-optical sockets.

Embodiment

As shown in Figure 1, no matter fiber-optical socket 3 and tail optical fiber plug are any forms, the slotting body 1 or the tail optical fiber sleeve pipe 2 of its tail optical fiber plug are circular-arc, the arc bend bilge radius is more than or equal to 7.5mm, less than 30mm, be preferably 7.5mm, the angle of its slotting body 1 and tail optical fiber sleeve pipe 2 is more than or equal to 90 °, less than 120 °, be preferably 90 °.

Claims (2)

1, a kind of tail optical fiber coupling arrangement, form by fiber-optical socket and tail optical fiber plug, it is characterized in that it is 7.5-30mm that the slotting body (1) of said tail optical fiber plug or tail optical fiber sleeve pipe (2) are the arc-shaped bend radius, insert body (1) and tail optical fiber sleeve pipe (2) angle more than or equal to 90 °, less than 120 °.

2, tail optical fiber coupling arrangement according to claim 1 is characterized in that the bending radius of said slotting body (1) or tail optical fiber sleeve pipe (2) is 7.5mm, and inserting body (1) is 90 ° with tail optical fiber sleeve pipe (2) angle.
