Abstract
The invention concerns a method of wrapping bus-bars for prefabricated electric ducts. An insulating sheath is prepared having the shape and dimensions of the bar to be covered, the insulating sheath is cut at some preset intervals; a bus-bar is housed in the shaped insulating sheath; the overlapping edges of the insulating sheath are sealed lengthwise using ultrasound welding or a glue; and the bar-sheath assembly is bent at preset intervals along its length. The invention concerns also the bus-bar achieved using this method.
Description
Technical field
The present invention relates generally to that prefabricated electric pipe (electric duct)-(bus bus-bar), relates in particular to a kind of (wrap) method of sealing that is used to form the busbar of described prefabricated electric pipe to be also referred to as busbar.
Background technology
Electric pipe is exactly in fact the electric wire of constructing according to projected route.They are made up of lid or seal bootr that the housing that is also referred to as section bar and of a side opening of a busbar is fixed on the shell nozzle side usually, and wherein busbar is placed in the housing and along the length of this housing and extends.Busbar is coated with an insulating case of usually being made by polyester resin usually to avoid when they are directly contacted when placed side by side.
The operation that covers busbar with insulating case is commonly referred to as seals, and this operates in the various methods of present usefulness and realizes.
For example, a kind of encapsulation system is each busbar all is encapsulated in one continuous or in the dielectric film of several portions.For example, another kind of encapsulation system be that each busbar is all inserted one may be in the heat-shrinkable tubulose insulation component.In any example, encapsulating method all exists a lot of problem well-known to those skilled in the art, a difficult problem and defective up to now, and is crooked so that adjacent electric conductor can be connected all the more so with terminal box busbar.
Summary of the invention
The present invention is intended to avoid effectively problem and the shortcoming in the known technology.
An object of the present invention is to provide encapsulating method a kind of novelty, original creation, mode that thus can an advantages of simple covers busbar successively and is crooked, its productivity ratio height, has reduced labour's demand and can reach effect preferably.
Another object of the present invention is the condition of sealing that is formed for the busbar of prefabricated electric pipe, its preparation one is in order to hold the insulating case of a busbar, and make insulating case that busbar and this insulating case can closely be centered around on the busbar in the course of processing before or after the bending together, and needn't (after bending) once more to they weld/bonding.
According to the present invention, these purposes realize that by a kind of encapsulating method that is used for prefabricated electric pipe this method consists essentially of:
-form shape and size and the cross section of the busbar that will be capped and the insulating case that length is complementary, and make vertical free edge part of this insulating case can be overlapping;
-busbar is put into the cover that has been shaped, make the longitudinal edge portions of this insulating case overlapping;
-longitudinally connect the partly overlapping edge of this insulating case so that this insulating case sealing and closely around the busbar of putting within it;
-according to this busbar of set location bending-insulating case assembly;
-can seal by welding or the partly overlapping edge that glues together this insulating case.
Description of drawings
The present invention will be described in more detail below with reference to exemplary and nonrestrictive accompanying drawing, wherein:
Fig. 1 shows an initial busbar;
Fig. 2 shows the insulating case that a shaping is used for coverage diagram 1 busbar;
Fig. 3 shows and is insulated the busbar that cover is sealed; With
Fig. 4 shows the crooked busbar that has insulating case.
Embodiment
According to the encapsulating method that proposes herein, initial busbar 11 is straight-Fig. 1, and being used for covering the insulating case 12 of busbar 11 by for example one section flat film moulding in advance that is generally polyester.The configuration of the cross section of insulating case 12 and length and busbar 11 is complementary, and vertical free edge 13 of this insulating case 12 has and is used for partly overlapping size-Fig. 2.If necessary, can must keep naked position some parts excision-Fig. 4 of insulating case 12 at busbar.
Busbar 11 is contained in the preformed insulating case 12, and the longitudinal edge 13 of insulating case 12 is overlapping in a side part of this busbar.
According to a kind of processing method, make 13 connections of partly overlapping edge it closely around busbar 11-Fig. 3 with sealing insulating case 12.Can preferably use ultrasonic wave or adhesive to come the edge is sealed along at least one sticking/sealing wire 15 continuous or that be interrupted.Thereby advantageously on busbar 11 always, therefore on a plane, realized this sealing to insulating case 12.
Then usually at end and zone line, for example corresponding to the cut part of cover with predetermined interval the busbar bending-Fig. 4 that has cover.Available clod wash or hot bending are with busbar-insulating case assembly bending.
According to other method, busbar 11 put into cover back just in the precalculated position with busbar clod wash or hot bending, then partly overlapping edge 13 sealings of grip so that its closely seal around this busbar.Equally, in this case, it is continuous or interrupted bonding that the method for sealing the margin can be that preferred use ultrasonic wave or adhesive carry out.
As a result, busbar its each part-comprise corresponding to the point of the most critical of bending area and in forming process the firm position of sealing insulating case-all be matched with in the insulating case rightly.
