Below in conjunction with accompanying drawing, with way of example explanation embodiments of the invention.Wherein:

Figure 1A and 1B illustrate the form that a kind of shutoff vehicle cable block head side enters the moulded plastic convex assembly that opening uses; With

Fig. 2 A and 2B illustrate extension crooked or the band angle, are orientated or follow its variation in order to the variation with the bundle conductor direction.

Referring to Figure 1A and Figure 1B, the mold pressing steel of the rubber coating that forms with two separation members or glass-filled nylon system convex assembly 14 are assemblied in around the bundle conductor 12, to form a bead jut 16 along the bundle conductor projection.With known heat-shrinkage material (having the 10-20% shrinkage after the heating) but make, its inner surface has the coating bonding agent adhesive tape 20 that the induction heating type spiral of the bonding agent (not shown) of induction heating twines and form a cover around being wrapped in bundle conductor 12 and bead jut 16, and be fastened with overlapping splicing tape, the cover 20 that is wound in taper covers any shutoff with bonding filler (not shown), this filler can be filled between the lead of bundle conductor, and this will be explained below.This assembly carries out induction heating with known method then, shrinking above-mentioned cover, and orders about shutoff and is filled in sticky object between the lead of bundle conductor, to make black box.Above-mentioned convex assembly 16 has the tapered flexible fingers of many integral body 17, discharging some stress, and forms mild transition 12 of convex assembly and bundle conductors with the cover that is wound in taper.Shown in side on extending transversely 18 shutoff bead end socket 22 enter breach 24, be intended to reduce or stop two relative edges' of this breach laterally the moving of potential destruction sealing.

Wall or bulkhead wiring feedthrough GB3

Convex assembly can be made by various materials, denser moulding material for example, glass-filled polypropylene, polyamide or ABS engineering plastics, so that desired clamping rigidity and sound insulation value to be provided, and other flexible plastic material, for the usefulness of flexible taper shaping, make it to be adjusted to flexibly various bundle conductor sizes.

The problem that the present invention will solve is to be positioned on the long stranded conductor bundle about the thermal contraction driver sleeve with the shutoff cable, and this bundle conductor must not passed this cover.The solution of this problem does not have the side import (" coiling ") cover is realized by this thermal contraction driver is made.The notion of this side import itself is known, and many ready-made structures adopt mechanical clamps or bonding lining, and the perhaps discrete item made of adhesive tape will be will overlap the maintenance one.With regard to the purpose of ready-made feeder means, the mechanical fasteners technology is not satisfied, forms sealing because it hinders on side import feeder means.Binding agent blocking technology is in the past failed often, because binding agent can not stop connected cover edge with common hot-air, when flame or infrared ray heating are shunk cover, slides mutually.

Heat in the bundle conductor that unique heat that various preferred induction heating technique provided that addresses this problem need should to equal sealing can be provided so far and flow to the heat in the outside of cover from the inboard of cover.In addition, temperature can be controlled effectively with magnetic field, because magnetic field intensity and magnetic density can be controlled, heating cycle also can be controlled.The toroidal winding (for example U-shaped coil or so-called " shell " shape coil) that this can enter with the side is realized with changing coil diameter and coil turn spacing.Adopt large-diameter coil, thereby reduce magnetic field intensity and can around the bead of feeder means assembly, realize low heating intensity, and the diameter of coil can reduce, and adapts with the tapered cross-section with bead, thereby improves the magnetic field intensity of the bundle conductor center that needs the formation airtight and watertight padding.At last, at the coil back segment around the cover part that exceeds bundle conductor shutoff district, the spacing between each coil turn can increase, to reduce magnetic field intensity.The Temperature Distribution of the length direction of whole like this cover can satisfy the requirement of every part, and the heat that adds of each position also can accurately be controlled and be adjusted.This meaning can reach in bundle conductor inside and cause shutoff airtight and watertight padding (for example hot-melt adhesive) fusing and the temperature that flows, and the twister around the overcoat can be in low temperature, otherwise will cause that bonding sealing adhesive tape destroys.This helps to select suitable binding agent, makes cover twister on every side keep whole.

The open tube that the technology that realizes that the winding cover seals has adopted the heat-shrinkable extruded tube of a kind of usefulness to make, but it is preferably made by the low temperature EVA composite material that the hot-melt adhesive of being with the particle (known) that adds induction heating serves as a contrast.This pipe preferably has 3: 1 shrinkages so that provide bead to the transition between bundle conductor.As an example, this pipe can be placed on around the bead that diameter is 35mm, and the heat-shrinkable tube of Xing Chenging is the same long with the bundle conductor district that needs shutoff like this.Adopt known high temperature pressure sensitive adhesive tape that open tube is fixed together.Open tube shrinks during the induction heating, with the bead shape that enters with the side and consistent by the cable of shutoff.Heat is controlled with the magnetic field that is applied to the bead place in the cover, and the convergent force at bead place may be maximum.The machinery means, for example bundling belt can be used for predetermined fixed open tube before contraction, and prevents to produce in heating and contraction process mobile.By with magnetic field concentration by the cable district of shutoff, promptly on the lead or be placed with the position of shutoff airtight and watertight padding between lead, it is maximum that the heat of generation can reach.EO can be removed adhesive tape before the cooling.

A kind of technology of replacing is that the vertical shrinkage of employing is about 50% adhesive tape, but the material of induction heating is contained in this belt inside, and this band just can heat in magnetic field like this; Perhaps but under the situation of the hot melting cohesion layer that adopts induction heating, this adhesive tape contains the material of non-induction heating.Heating can be by magnetic field grade and density control (changing loop construction by the part realizes).This adhesive tape can apply hot-melt pressure sensitive, perhaps hot melt bonding coat, and this coating has many pressure sensitive adhesives, to assist the location.Suitable adhesive tape can for example, push before electron beam crosslinking and orientation with known method formation in fact, given then electron-beam dose, and maximum vertically shrinkage is locked in only 25 to 50% residues.This adhesive tape should be around bead, and spirality is wrapped on the dactylozoite on the cable, covers the cable that has the shutoff airtight and watertight padding, terminates on the cable surface at last.In the induction heating process, heat can concentrate on the cable section that needs shutoff with coil device, and is minimum at two ends, causes that with minimizing adhesive tape is in cable surface moves or the excess shrinkage power of sliding is brought risk.Length of tape can produce the trend of shortening, thereby compresses following assembly and form one with it, and bonding coat can be integral the envelope of the adhesive tape after twining, and with its shutoff on bunch of cables and bead inside.Lower another advantage of adhesive tape shrinkage is that the power that is applied to the cable occluding member in the operating process is less, thereby has reduced the impaired risk of temperature-sensitive wire insulation.

For this system, be to obtain optimum efficiency, preferentially adopt wide as far as possible bonding shutoff shape, with the height of shutoff binding agent in before contraction process, reducing to overlap.Pile up together when each shutoff adhesive tape, when reaching desired shutoff airtight and watertight padding volume, total heap is piled up highly may be greater than cable size, and it should be higher than desired adhesive tape shrinkage.This can be avoided by using individual layer shutoff airtight and watertight padding, for example has basic flat pattern, the band that perhaps has the outer extension member (being commonly called as " centipede worm band ") between a plurality of insertion leads, its width is preferably the desired width that equals occluding body substantially, profile is suitable with the less entity that the heap of shutoff airtight and watertight padding is piled up, and promptly has only 7mm wide.By reducing component count, this individual layer shape also makes work simplification.

The application on the other hand correspondingly with the fixing relevant of cover of reeling, for example fixed form of ubi supra, the perhaps fixed form with the coating adhesive tape that bonds of ubi supra.This respect also provides said modules or external member, particularly apply under the situation of follow-up induction heating, wherein said cover is the cover with sheet material or the band longitudinal opening that is wound into, be suitable for perhaps that winding method provides, bundle conductor and bead or convex assembly and fixture are that the form with the pressure sensitive adhesive tape or the roll coil of strip provides, with the cover fix in position that will be wound into.

As above pointed out, monovolume around closure, for example above-mentioned with adhesive tape or coat the fixing sheet material of adhesive tape or the cover of band opening, when the cover that is wound into need be with the disclosed induction heating modularity heat shrink of respectively applying in above-mentioned the examining, work well unusually, can be with or not be with the auxiliary fixedly roll coil of strip or adhesive tape.The unexpected success of the bonding coiling sealing mode of heat shrinking sleeve perhaps is because due to the inboard induction heating that produces contraction heat of assembly, it with in the past can to produce hot-air or flame external heat that coiling closure bonding fails as everyone knows significantly different.

The heat shrinking sleeve itself that closed side enters (" coiling ") that bonds just should be regarded invention as.This induction heating can by the thermoinduction material production (for example: cover, preferably on Tao the inner surface or the thermoinduction particle that carries of inner surface annex; Perhaps Tao coating on inner surface, for example the thermoinduction particle that carries of hot melting cohesion coating; Perhaps on the bundle conductor or the thermoinduction particle that carries of the airtight and watertight padding of using for sealed guide bundle internal pore in the bundle conductor), perhaps the induction heater that is made of the wire in the bundle conductor produces, perhaps the combination in any by them produces.

The application provides said modules or external member on the other hand, perhaps according in the claim 1 to 16 in the GB Patent Application No. 9603629.8 each, perhaps according to each assembly that provides or external member in the claim 1 to 14 in the GB Patent Application No. 9606393.8 and 18 to 22, wherein said cover provides with taper, can be arranged to from the cone of described convex assembly towards the bundle conductor surface before any thermal contraction of cover during use.

When applying induction heat on taper bead or assembly, the conical pipe or the tapered opening cover that adopt said method to constitute can reduce a large amount of uncompleted contractions, and this is to take place in the straight tube cover.Yet preferred solution is to adopt above-mentioned helical coil strip winding, to form described taper sheath.

Correspondingly, the application provides said modules or external member on the other hand, the tapering part of wherein said cover, be to be used in the method for twining two-layer or multilayer rubber or plastic tape around the tapering part of described bead or convex assembly to form, but described band is preferably with the fluid sealant or the binding material of heat effect.

But above-mentioned band is preferably with the sealant layer of induction heating, is preferably the type that aforesaid and/or aforementioned UK Patent Application kind is addressed, and the disclosed content of these patent applications should comprise in this manual as a reference.The above-mentioned best spirality ground of being with is from the bundle conductor surface, and through the thinner end of taper bead or assembly, to thicker end, complete trails is entwined, and continuous spirality volume is optimally arranged, to reduce potential leakage paths.

Ask on the other hand in this, provide a kind of and made bundle conductor block head feed-in assembly by induction heating, be preferably formed as the manufacture method of said modules, wherein (ⅰ) is by the taper coil consistent with bullet, on bullet, carry out induction heating and/or (ⅱ) this induction heating coil effect, spacing between the adjacent turn of this coil can change, with when work along magnetic field that the coil length direction changes.Adopt tapering how much to follow the tapering of the assembly that needs induction heating, can be more effectively with the induction heating the action of a magnetic field in this assembly.Induction coil itself this taper or variable spacing perhaps should be regarded a distinguishing feature as, therefore the present invention includes a kind of like this coil, and it is specially adapted to above-mentioned bundle conductor shutoff feed-in assembly is carried out induction heating.

The application on the other hand, provide coiling sheet or the cover made with the heat-shrinking plastics that has the induction heating material, preferably the coating on inside surface contains the induction heating material when the use of sheet or cover, also have binding agent simultaneously, pressure sensitive adhesives preferably, so that sheet or cover are fixed with its reeling condition, preferably before induction heating makes above-mentioned plastic shrink, fix by superimposed adhesive tape.But the coiling cover that this induction heating shrinks is preferably used for making said modules.

Be used to form the load coil of said modules, be combined with or have, the positioner that the assembly that will heat during use accurately is positioned at an accurate precalculated position in the magnetic field that coil produces is should be preferred.Above-mentioned positioner perhaps also comprises for example anchor clamps class formation, the suitable part of above-mentioned convex assembly can be fixed in this structure, each bundle conductor that needs order therefrom to pass through can be positioned substantially at same position like this, so that carry out the induction heating operation on the assembly line in for example automatic wiring workshop.
