Abstract

The invention relates to a compact type cable hut which comprises a base, two side plates, two or more cable fixers, a protective cover and a shunting device, wherein the protective cover comprises a first-half protective cover and a second-half protective cover which are detachably connected; the shunting device is arranged in the protective cover and used for shunting a branch cable from a core wire of a main cable; and the side plates, the cable fixers and the protective cover are all in double-piece structures, thereby ensuring that the hut can be arranged on laid cables without cutting off the main cable. In addition, after the main cable is fixed through the cable fixers by the compact type cable hut, the core wire can be stereoscopically shunted in the hut body, and the shunting device is flexibly distributed, so that the side of the hut can be reduced, and the hut is convenient to mount in construction, which is specially useful in a vertical shaft with a limited construction range; and meanwhile, conductor deformation while shunting can be reduced. In addition, the flame resistant grades of cable sections which are not armored are recovered under the protection of the protective cover.

Description

The compact cable coupling box

Technical field

The present invention relates to a kind of cable hut, relate in particular to a kind of armoured cable coupling box.

Background technology

Along with rapid development of economy, high level and high-rise building are increasing.Therefore, also increasing to the demand of cable branch.The T that generally uses in the industry at present connects case and only is suitable for the tap mode of blocking cable.Main line branch when some junction boxes can realize that cable does not cut off is the enclosed construction design but this type of junction box adopts, and promptly the junction box inserts in cable laying.And this type of junction box do not use cable retainer, and all cables are fixed through binding post, and binding post is fixed on the terminal box.Because adopt fixed connection terminal, all cables need be fixed on the plane, concerning multicore cable, need the conductor distortion bigger.

Because the structural design of itself, there is following problem in the junction box of prior art: (1) need be blocked cable and could insert, and perhaps need in cable laying, insert, and can not install flexibly; (2) size is generally bigger, when actual installation, particularly in the limited vertical shaft of boundary of works area, installs inconvenient.

Therefore, be badly in need of a kind of cable distribution box that can under the situation of not blocking leader cable, realize installation flexibly and compact conformation in this area.

Summary of the invention

The object of the invention just provides a kind of cable hut, and it can not destroy the flame retardant rating at cable distribution place being installed under the situation of not blocking cable on the cable that has laid, and compact dimensions, easy construction.

For realizing above-mentioned purpose, a kind of compact cable coupling box is provided, comprising: base; Two side plates; It is installed in the two ends of base respectively on leader cable passes the direction of said coupling box; Each said side plate comprises confession leader cable cable passage that passes and the branch line passage that supplies branch line to pass, and each said side plate comprises first fixed head and second fixed head of opposition, and at least one said fixed head is removably mounted on the base; And each said fixed head comprises a recess, when said first and second fixed heads all are installed on the base, to form said cable passage; Two or more cable retainer are installed at least one said cable retainer on each said side plate, said cable retainer comprises first member and second member of opposition, and said first and second members removably connect with fixing leader cable; Guard shield, it comprises removably the first and second half guard shields that connect; And tapping device, it is positioned at guard shield, is used for picking out branch line from the heart yearn branch of leader cable.

The side plate of compact cable coupling box of the present invention, cable retainer and guard shield all are two-part construction, and this makes it possible to be implemented under the situation of not blocking leader cable this coupling box is installed on the cable that has laid.In addition, use three-dimensional tap mode in the casing, but therefore the tapping device flexible arrangement can reduce the size of coupling box in casing, make it in construction, be convenient to install, this is particularly useful in the limited vertical shaft of boundary of works area.In addition, the cut cable that does not have armouring has recovered flame retardant rating under the protection of guard shield.

Preferably, said cable retainer is adjustable cable retainer, and said first and second members are removably connected with according to the distance between said first and second members of the diameter adjustment of leader cable by bolt.This makes can the different armoured cable of fixed diameter.

Preferably; Said first member and second member comprise interior clamping element respectively; Clamping element can not only slide and can rotational slide reel and guarantee that fastening the contact avoiding skid with the appropriate cable armor being parallel on the axial direction of cable in said; And preferably, said interior clamping element has semicircular surface to cooperate the cable outer surface.

Preferably; Said the first and second half guard shields are removably mounted on the base by threaded fastening device; And have upper and lower hook shaped ends respectively at the place of being bonded with each other, the upper and lower hook shaped ends of the correspondence of the upper and lower hook shaped ends of said the first half guard shields and said the second half guard shields is coupled together by the plug-in type seal respectively.The guard shield installation is more convenient like this, and saves the space.

Preferably; Said the first and second half guard shields are installed on the base by dismountable hinge structure in the lower end respectively; And hook shaped ends on the upper end has respectively, the last hook shaped ends of the correspondence of the last hook shaped ends of said the first half guard shields and said the second half guard shields is coupled together by seal.

Preferably, said recess is semicircle, when said first and second fixed heads all are installed on the base, to form circular said cable passage.

Preferably, in the said branch line passage said fixed head located therein, this fixed head is fixedly mounted on the base.

Preferably, said coupling box comprises four said cable retainer, in the both sides of each said fixed head a said cable retainer is installed respectively.

Preferably, said seal is processed by stainless steel, has the not cross section of occluded ellipse shape.

Preferably, said base is processed by galvanized steel plain sheet, and said side plate, said cable retainer and said guard shield are processed by stainless steel.
