Abstract
The utility model discloses a flexible single-core fireproof cable pre-branching coupler. The coupler is equipped with copper pipes, wherein two ends of each copper pipe are sealed by sealing caps, a sealing chamber is then formed, and one end of a main cable penetrates through one sealing cap, is positioned inside the sealing chamber, and is branched into branch cables via an insulating coupling head. According to the utility model, when the main cable is coupled to the branch cables, it is not required to break the main cable, and the coupler is made of a high temperature resistant material, simple and practical in structure, small in size, low in weight and convenient for reeling and transporting.
Description
[technical field]
The utility model relates to a kind of cable coupler, especially relates to the pre-branch of the single core fire-resisting cable of a kind of flexibility coupling.。
[background technology]
Existing cable coupler, lead, when branch cable connects, need leader cable is disconnected, then do collateral branch along separate routes, cause thus that coupling increases, node contact resistance variation factor is many and the drawback of fault point, and the material non-refractory of coupling, volume is heavy, many inconvenience are in use arranged, therefore be necessary to improve.
[utility model content]
The technical problem that the utility model solves provides the pre-branch of the single core fire-resisting cable of a kind of flexibility coupling, main, branch cable does not need when connecting leader cable is disconnected, and the material of coupling all adopts high temperature resistant material, and is simple and practical, volume is little and slim and graceful, is convenient to reel and transportation.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the pre-branch of flexible single core fire-resisting cable coupling, has copper pipe, described copper pipe two ends are with the sealing cap rear formation seal chamber that is tightly connected, leader cable one end passes sealing cap and places in the seal chamber and by the insulation coupling head and tell branch cable, and described leader cable and the branch cable other end pass sealing cap.
Further, described sealing cap inboard is provided with sealing gasket, and the place that described sealing cap is connected with branch cable for leader cable is equipped with sealing ring and sealing ring and is connected with sealing cap and scribbles fluid sealant.
Further, described sealing cap is the hexagonal sealing cap and adopts copper material to make.
Further, described insulation coupling head adopts fire-resistant inorganic insulating material to make.
Further, described fluid sealant and sealing gasket all adopt anti-spray encapsulant to make.
The utility model beneficial effect compared with prior art is:
1, leader cable does not disconnect, and directly does bypass branch, has avoided leader cable to disconnect and has done bypass branch, causes the drawback that coupling is many, node contact resistance variation factor many and the fault point is many, node heating or the fault such as open circuit;
2, all structural materials all are copper materials, and identical with the cable jacket material, and the ability of its tolerance flame is identical with cable, so can tolerate 950 ℃+50 ℃, the product standard regulation that fire duration 180min is above;
3, bifurcation (i.e. main, branch cable connection place) insulating material is that inorganic insulation material (mica tape) has the identical fiery ability that is subjected to cable insulation material, can reach 950 ℃+50 ℃ flame temperatures, and the ability that did not lose efficacy more than the fire duration 180min;
4, about this product length 250mm, about diameter 80mm, wall thickness 3-4mm, lean on two ends hexagonal sealing cap and sealing gasket, fluid sealant to seal space in this container, cut off with ambient atmosphere, protection bypass connection place insulation is not subjected to external environment influence, and is simple in structure, practical, slim and graceful, and because volume is little, be convenient to reel and transportation; Simultaneously leader cable does not disconnect, and good hauling ability is arranged, namely can whole piece transmitting loop integrally dragging, and needn't be as the bypass distribution box, need step traction, connection, and easy construction;
5, totally-enclosed because of the coupling inner chamber and structural material is high temperature resistant, during breaking out of fire, the water spray that fire-fighting lance produces and the shock of a fall of burning material can not cause damage to coupling, thereby guarantee that the fire-fighting distribution loop powers continuously;
6, because coupling copper pipe sheath props up a conducting by wedge sealing ring and master, outer the protecting of branch cable, so can working as the PE line, this type protective coverings of cable uses.
[description of drawings]
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, consists of the application's a part, but does not consist of to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model.
Description of reference numerals: 1-copper pipe; The 2-sealing cap; The 3-seal chamber; The 4-leader cable; The 5-coupling head of insulating; The 6-branch cable; The 7-sealing gasket; The 8-sealing ring; The 9-fluid sealant.
[embodiment]
Below in conjunction with accompanying drawing 1 embodiment of the present utility model is described.
The pre-branch of flexible single core fire-resisting cable coupling, has copper pipe 1, described copper pipe 1 two ends are with the sealing cap 2 rear formation seal chamber 3 that is tightly connected, leader cable 4 one ends pass sealing cap 2 and place in the seal chamber 3 and by insulation coupling head 5 and tell branch cable 6, described insulation coupling head 5 adopts fire-resistant inorganic insulating material to make, described leader cable 4 and branch cable 6 other ends pass sealing cap 2, described sealing cap 2 is for the hexagonal sealing cap and adopt copper material to make, described sealing cap 2 inboards are provided with sealing gasket 7, described sealing cap 2 is connected the place passed for leader cables 4 and is equipped with sealing ring 8 and sealing ring 8 and is connected with sealing cap 2 and scribbles fluid sealant 9 with branch cable, described fluid sealant 9 and sealing gasket 7 all adopt to be prevented spraying encapsulant and make.
The utility model is that flexible fireproof cable is special-purpose when carrying out branch, and in the cable production scene, after completing in advance, reel is transported to the cable erecting bed, directly lays, and send the purpose of electricity to reach the leader cable bypass branch.
The above is only in order to convenient explanation the utility model, and in the spiritual category that does not break away from the utility model creation, that is familiar with that those skilled in the art of this technology does various simple in a disguised form still belongs to protection range of the present utility model with modification.
