Background technology

The utility model relates to a kind of optical cable welding point protection device of registering one's residence, and is used for the protection to the welding point of the optical cable of registering one's residence.

Technical field

Along with the development and the fiber-to-the-home popularization of optical communication, the optical cable of registering one's residence is employed under a lot of local and a lot of situations.

Under existing situation, after the optical cable welding of registering one's residence, with heat-shrinkable T bush protection, but heat-shrinkable T bush can not be protected with the bare fibre part of registering one's residence between the optical cable, is easy to herein rupture.

In sum, at the defective of prior art, need a kind of protective device of the optical cable welding point of registering one's residence especially, to solve above-mentioned problem.

The utility model content

The purpose of this utility model is to provide a kind of optical cable welding point protection device of registering one's residence; solve the defective of above-mentioned prior art; to covered wire cable welding point, and welding puts the part of registering one's residence between the optical cable and all protects, to increase reliability, permanance and the physical strength of welding point.

The technical matters that the utility model solved can realize by the following technical solutions:

A kind of optical cable welding point protection device of registering one's residence; it is characterized in that; it comprises loam cake, end box and optical fibre clip; the ccontaining respectively and fixing described optical cable in the two ends of the bottom surface of box of the described end is sandwiched in box inside, the end; described optical fibre clip is provided with U-lag; this U-lag surface is provided with some parallel racks, the end face of described loam cake be at the bottom of U-shaped and its complete closed box above.

Wherein, described end box is at the middle part of bottom surface projection one U-shaped thermal shrinkable sleeve tube seat.

Wherein, the two ends of two sides of described end box are respectively equipped with the bayonet socket that cooperates loam cake.

The optical cable welding point protection device of registering one's residence of the present utility model compared with prior art has following advantage:

(1) adopted and adding a protective device in the optical cable welding point protection heat-shrinkable T bush outside of registering one's residence and make the welding point of protective device inside and heat-shrinkable T bush and the optical fiber of registering one's residence between the optical cable obtain good protection, can not be subjected to pulling force, pressure, bending power and deformation.Guaranteed the transmission of light signal in optical fiber.

(2) optical fiber in the protective device can not produce flexural deformation, therefore can not cause the bending loss that light signal transmits in optical fiber;

(3) optical cable of registering one's residence has adopted the structure of sawtooth tooth bar in being fixed on the optical fibre clip of registering one's residence the time, makes the optical cable of registering one's residence add hold tighter like this in the optical fibre clip of registering one's residence, and is difficult for being drawn out.

The utility model well protects by the protective device optical cable welding point of will registering one's residence; after having solved the optical cable welding of registering one's residence, heat-shrinkable T bush and heat-shrinkable T bush do not have the problem of protection to the one section optical fiber between the optical cable of registering one's residence; make that the welding point is well protected; and has better reliability; welding point and the impaired possibility of optical fiber have been reduced; having designed novel register one's residence optical fibre clip and loam cake, end box device in addition makes and the simple and operation easily of device realizes the purpose of this utility model.

Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.
