Abstract
The utility model relates to a clamp-connection type explosion-proof box for an intermediate joint of a cable. The clamp-connection type explosion-proof box comprises a first cylindrical shell and a second cylindrical shell. One end of the first cylindrical shell and one end of the second cylindrical shell respectively have a tightening port. A far end of the first cylindrical shell from the tightening port has a plugging cavity formed by a hole reaming technology and a flange which extends outwardly in a radial direction is arranged at an end edge. A bottom part of the plugging cavity forms a circular step surface. The flange is provided with a clamp plate which extends axially. An end part of the clamp plate is provided with a wedge-shaped clamp connection part. The end surface of a far end of the second cylindrical shell from the tightening port extends axially to form an annular sleeve. The annular sleeve abuts against the circular step surface to achieve muff coupling with the plugging cavity. The outer periphery of the first cylindrical shell is provided with a clamp groove at a position corresponding to the wedge-shaped clamp connection part. The wedge-shaped clamp connection part at the end part of the clamp plate is in clamp connection with the clamp groove. The explosion-proof box is simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment of high-voltage cable middle joint, is specifically related to a kind of plug-in anti-explosion box for cable middle connector.
Background technology
Those skilled in the art should know, anti-explosion box for cable middle connector of the prior art generally comprises two semicylinder shells that connect, and then form the flame proof inner chamber between two semicylinder shells, yet, the anti-explosion box for cable middle connector of this kind structure is because the flange that connects is longer, and then causes the flame proof gap of interface also longer, is used in the bolt use amount of interface position locking armored cassette relatively many, and it is feasible that the distribution of bolt has no rule, and production cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of simple and compact for structure and plug-in anti-explosion box for cable middle connector that can effectively reduce production costs is provided.
for achieving the above object, the utility model adopts a kind of plug-in anti-explosion box for cable middle connector, comprise the first cylindrical shell and the second cylindrical shell, a wherein end of described the first cylindrical shell and described the second cylindrical shell has respectively the mouth of tightening, the described mouth that tightens has the through hole that passes through for cable penetration, have in an end that tightens mouth the grafting cavity that is processed to form by reaming at a distance on described the first cylindrical shell, the annular step surface is formed on the bottom of this grafting cavity, and have in the end edge edge that tightens mouth the flange that extends radially outwardly at a distance on described the first cylindrical shell, be provided with the clamp that extends axially and radially inwardly be the minute angle inclination on described flange, the end of this clamp is provided with the wedge shape Access Division, on described the second cylindrical shell, at a distance extended axially annulus on its end end face that tightens mouthful, this annulus forms socket with described grafting cavity by the form that is connected to the annular step surface, on the outer circumference surface of described the second cylindrical shell, the position corresponding with described wedge shape Access Division offer buckling groove, the wedge shape Access Division of described clamp end and described buckling groove form clamping.
Concrete, for the overall structure that makes armored cassette is compacter, the docking location of described the first cylindrical shell and described the second cylindrical shell is provided with elastic rubber layer.
Concrete, on the inwall of described the first cylindrical shell and the second cylindrical shell, the close neighbour is provided with fireprotection layer, describedly tightens close neighbour on mouthful through-hole wall at place and is provided with axial waterstop.
The utility model is by the above-mentioned improvement to prior art, reached the beneficial effect of following two aspects: 1, due to after the first cylindrical shell and the second cylindrical shell are connected together and pass through the Access Division and buckling groove formation clamping of clamp end, with respect to armored cassette of the prior art, cancellation obviously the use of bolt, and simplified assembly process, therefore, when having improved production efficiency, effectively reduce production cost; 2,, owing to being provided with axial waterstop on the through-hole wall tightening the mouth place, prevented that further outside moisture from entering the armored cassette inner chamber by cable with tightening mouthful gap at place, reached fabulous block-water effect.
