Abstract
A novel cable branch joint protection box belongs to a cable connection protection device. The existing branch joint protection box has the defects of difficult secondary operation and maintenance for a sealing structure. The protection box comprises a shell body which is combined by a box cover and a box bottom by butt joint. The two ends of the shell body are provided with circular through holes; a seal groove which is internally provided with a seal gasket is respectively arranged on the butt joint surface of the shell body and the inner wall of the through holes; the thickness of the seal gasket is larger than the depth of the seal groove; the through hole at one end of the shell body is provided with a seal ring; and the shell body is provided with an air tap which is communicated with the cavity of the shell body. By the sealing of the seal gasket and the seal ring, the protection box has good sealing performance; and the jointing and installation operation of the cable is convenient, and the cable can be reusable.
Description
Technical field
The utility model relates to a kind of cable and connects protective device, and is especially relevant with a kind of novel branch cables joint protection box.
Background technology
Cable or optical cable cable bundles use protective sleeve with many cable boundling suits, when needs carry out branch or jointing, each root cable are separated the protective sleeve strip off.Need carry out encapsulation process in branch and joint, prevent that cable other media under abominable operational environment from entering in the protective sleeve or influence the laser propagation effect of cable in the joint.At present, people adopt the way of artificial rubber to realize the sealing function at cable protection cover and cable joint place, and still, such hermetically-sealed construction all is disposable operation, can't carry out the joint second time again in the original place, make maintenance difficult.
The utility model content
The purpose of this utility model is exactly to solve the hermetically-sealed construction secondary operation of existing branch cables joint protection box and the defective of maintenance difficult, and a kind of good sealing effect, branch cables joint protection box easy to use are provided.For this reason, the utility model is by the following technical solutions:
A kind of novel branch cables joint protection box, comprise housing, it is characterized in that: described housing two ends are respectively arranged with manhole, two parts formed two interfaces at the bottom of housing was divided into lid and box by the cross section of the center line by described through hole, connect two parts butt joint at the bottom of the lid of housing and the box fixing by screw, all be provided with seal groove on the described interface and on the inwall of described through hole, be provided with sealing gasket in the seal groove, the thickness of sealing gasket is greater than the degree of depth of seal groove, and the seal groove on described interface and the through-hole wall interconnects perforation; Described housing wherein be provided with the cylindrical seal circle in the end through hole, sealing ring is provided with a plurality of axial holes.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Be respectively arranged with many seal grooves on the through-hole wall at described housing two ends, the sealing gasket in each bar seal groove is connected as a single entity by a brace.
Sealing gasket on the through-hole wall at sealing gasket on the described interface and described housing two ends is connected as a single entity.
Described housing is provided with the valve that communicates with the inner chamber of housing, can be by valve to input pressure air in the housing, be used for installing in the check protection box sealing after cable and the butt joint.
When the utility model uses, the axial hole by sealing ring one by one with branch cables earlier, inner chamber at the bottom of the box of again sealing ring and cable being packed into is fixed lid with docking at the bottom of the box then, and cable and sealing ring are laid respectively in the through hole at housing two ends; Install the back and inflate toward the housing inner chamber, be used for checking the sealing of housing by valve.
Use the utility model can reach following beneficial effect: easy for installation, good airproof performance.
