Description

Connecting device for optical cable

Technical Field

The utility model belongs to the optical cable auxiliary connection device field especially relates to a connecting device for optical cable.

Background

In recent years, optical fiber technology has been widely used in many fields because of the great improvement in information transmission, reception quality, and transmission speed of optical fibers over the use of previous electronic conductors.

However, due to the severe conditions of some use environments, such as high temperature and high pressure, vibration, corrosive fluids, etc., the optical fiber is easily damaged under the action of these conditions alone or in combination, resulting in premature failure of the optical fiber relative to other applications. The hydrogen ions in the working environment of the optical fiber can cause the increase of the transmission loss of the optical fiber after acting on the optical fiber, in addition, the hydrogen ions outside the optical cable can also permeate into the optical cable to cause the hydrogen loss of the optical fiber, and the optical cable itself can generate hydrogen which can cause damage to the optical fiber due to the degradation of polymers in materials, electrochemical corrosion of metals and the like independently or together, so the contact between the optical fiber and the hydrogen environment needs to be reduced or avoided. The welding between the optical fibers is bound to occur according to the requirements of the connection between the optical fibers and the optical fiber sensor, the extension of the optical cable and the like, and the welding point of the optical fibers is easier to damage than the welding-free point after the welding, so that a device which can strictly avoid the influence of severe environment on the welding point of the optical fibers is needed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a connecting device for optical cable aims at solving the problem of adverse circumstances to the influence that the optical fiber welding point department produced.

The utility model discloses a realize like this, a connecting device for optical cable, its characterized in that: including first connector and second connector, first connector includes outermost casing, outermost casing tail end is equipped with the round axle body, the round axle body is kept away from outermost casing one end is equipped with first screw thread, the round axle body is formed with six first optical cable through-holes, outermost casing skin evenly is equipped with four fixed plates, the fixed plate intermediate position is equipped with the fixed orifices, the second connector includes the casing, the casing internal diameter be equipped with can with first screw thread second screw thread that mutually supports, the casing is formed with second optical cable through-hole.

Furthermore, a sealing rubber ring is arranged at the edge of one end, close to the fixed plate, of the outermost shell, and a sealing rubber ring is arranged between the second connector base and the second thread.

Furthermore, the first connecting body and the second connecting body are made of aluminum alloy.

Furthermore, the fixing plate and the outermost shell are connected by welding.

Furthermore, the first cable through hole and the second cable through hole have the same aperture and the same axis.

Further, the included angle between the adjacent fixing plates is 90 degrees.

Compared with the prior art, the beneficial effects of the utility model are that: because the utility model discloses be equipped with the split type design of first connector and second connector, can effectively protect the junction under the condition that remains sufficient space for the junction, the protection to more end optical cable can be realized to the design of first optical cable through-hole and second optical cable through-hole simultaneously.
