Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

It is to be noted that, unless otherwise indicated, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

In the present application, where the contrary is not intended, the use of directional words such as "upper, lower, top and bottom" is generally with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, perpendicular or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the invention.

The OPGW (Optical fiber Composite Overhead Ground Wire) splice closure generally adopts a cap type structure, and includes a housing structure, an internal component, and the like, where the housing structure includes a box body, a base, and a connecting member therebetween.

In the prior art, the compression between the box body and the base is generally realized by adopting steel belt fastening, when the box body is fixed by adopting a stainless steel belt and is continuously packaged on site, the stainless steel belt is easy to twist and rotate, so that the site fastening process is difficult to control, and the sealing quality of the joint box can be directly influenced. Base, box body and sealing washer form triangle-shaped seal structure when sealed, because box body edge machining precision is not enough with reasons such as manual operation, rubber circle compression ratio control is accurate inadequately. When the compression ratio of the rubber ring is too high, the rubber ring can generate permanent deformation and lose the sealing performance; when the compression ratio of the rubber ring is too small, the sealing effect is poor, and the sealing effect is also influenced. The sealing washer is extruded and is produced the deformation after the stainless steel band fastening, because do not draw close completely between base and the box body lower limb, the sealing washer is extruded from between base and box body, and exposed sealing washer can be ageing with higher speed, influences sealed effect.
