Description

Molded cabling and a method of production

The present invention relates to a kind of molded cabling and a kind of production method, especially use the multiple conducting wires cabling of plastics class molding compounds (plastic molding compound) braiding and a kind of production method of molded cabling.

Electrical cable has diversified shape, wire type, number of lead wires, insulator and structure.Electrical cable can be simple solid conductor, the lead outside is wrapped up in one deck insulator simply, electrical cable also can be complicated to having different size and dissimilar multiple conducting wires, along having different tip nodes or leading point (exit point) on the cable length direction.Cabling also can have multiple terminating device at the end of lead, perhaps looks concrete use occasion, also can be made into exposed shape.

Some electrical cable in fact often is used in each equipment that is equipped with electronic circuit or electronic component.Cabling often is required to make power supply and electronic equipment to fuse, and the signal of telecommunication is transmitted and be transferred to other electronic equipments, instrument, gauge outfit, optical indicator or other visual detectors, thus communication between the realization equipment and coordination.Whenever must transmit any type of electronic signal or electric current or be transferred to another equipment from an equipment, all will use cable usually.

Usually, when between sophisticated equipment or machine, transmitting composite signal or electric current, adopt custom cable with multiple conducting wires and a plurality of terminations.

Custom cable often is applied to military equipment, computer, TV, some phone, stereo and some other be difficult to imagine, equipment of using electronic technology of automobile, truck, aircraft, jet engine, rocket, other type.

The cable of prior art can be made with several different structures and method.Usually, in a shell or shell, multiple conducting wires is housed.Shell can be with distinct methods of the prior art parcel or molded.The cable that molding technique finally causes the outside of multiple conducting wires to be wrapped by certain molding compounds (molding compound).Cable can be a kind of structure in several different structures.Cable can be flat belt-like, also can be modal circular configuration.Multiple conducting wires can be and is parallel to each other, and also can decide on the type of specific application occasion and lead, is looped around together mutually with certain Weaving pattern.

In the example of prior art, electric lead is with a kind of special pattern braiding, and promptly the outside of main signal line is wrapped with the many non-leads that carry signal, can avoid the interference of other signals like this.Non-holding wire can be the lead that is loaded with electric current, also can be earth lead.In most of the cases, the braided wire outside is wrapped with one deck insulating material.

Use in some special occasions of customization cabling, usually have lead several different parts of cable into and out of, and each position has certain terminating device.Such cable usually adopts certain to be in particular this application scenario and the preparation of the anchor clamps that design.Lead, or is installed one group by one group by a ground along anchor clamps.Each root lead or each group lead is superimposed on the cable on some ad-hoc location, and terminating device is left enough cable extension length, and terminating device can be linked to each other with certain electric device.In case all leads put in place, just cable is wrapped up, or cable is carried out mold treatment with a kind of insulating material, cover thereby make cable be insulated material.Under latter event, insulating material fills up all spaces between the lead usually fully, and wraps lead fully, forms an insulating material overcoat around cable.

The cabling of prior art has several weak points.In case when multiple conducting wires is included in the cable, be difficult to a certain lead keeped in repair.Generally, cable and outer layer insulation material must be peeled off a sufficient length, come orientation problem where to appear at, if must change this lead the time, must be from an end to the other end complete peeling outer layer insulating material.If each lead is woven together with certain pattern, then can't peel off or repair a certain lead usually.If lead is wrapped in certain molding outer casing,, just can't peels off or repair solid conductor if do not destroy the integrality of cable.

Another weak point is to be used for to make the weight of the insulating material of cable.In some cases, in fact the weight of insulating material can surpass the weight of lead in the cable.Some uses the occasion of electric cabling that very strict requirement is arranged.The device of particularly using cable has under some motion or the mobile situation all the more so, as automobile, aircraft, spaceship and other military affairs with unmilitary application occasion under, only lift several examples here.

Correspondingly, one object of the present invention is to provide a kind of molded cabling and a kind of production method, adopts this method can produce a kind of electrical cable that overcomes the several defectives of prior art.

Another goal of the invention of the present invention is to provide a kind of cabling, and the total weight of this molded cabling has alleviated compared with the total weight of analogous cable of the prior art greatly.

Further goal of the invention of the present invention is to provide a kind of molded cabling, and the solid conductor in this molded cabling is easy to be stripped from, repairs or changes, and does not damage the integrality of whole cable.

Another goal of the invention of the present invention is to provide a kind of molded cabling, and this molded cabling is used for being formed for the custom cable of special application occasion, has a plurality of discrepancy ends on the cable, and each end of coming in and going out has special terminating device.

Another goal of the invention of the present invention is to provide a kind of method of producing molded cabling, makes a kind of braiding molded cabling according to the present invention.

Another goal of the invention of the present invention is to provide a kind of molded cabling with bigger flexibility.

In order to realize above-mentioned and other goals of the invention, the invention provides a kind of molded cabling and production method, or rather, a kind of electric lead braid is provided, lead wherein is not to use lead through braiding around the place of solid conductor, but with a kind of moulding material of plastics class.

Molded cabling and production method contain multiple conducting wires usually, and, keep and secure wires with a certain spacing relation with a kind of plastic materials with lead with a kind of Weaving pattern weaving together.The Weaving pattern of plastic materials forms with a kind of injection molding technology usually.

Cable can contain multiple conducting wires, is stamped first lead, second lead usually, until the mark of last root lead utilizes the Weaving pattern of plastic materials to leave a determining deviation mutually between the lead.One fillet molding combination materials forms an initiating terminal around lead, weaves above the lead at first then, weaves below second lead again, again around weaving above the lead to the 3rd, and is woven into last root lead with this Weaving pattern always.Then,, oppositely each lead is woven, be woven into first lead always, thereby each lead is woven together with a certain spacing relation around last root lead.This Weaving pattern repeats to a final position always, and forms an end end at nearly destination county around lead.

Foregoing invention purpose of the present invention, other goals of the invention and feature can be better understood from the detailed description of the main embodiment hereinafter selected for description and accompanying drawing.

Fig. 1 one contains the vertical view of the molded cabling of multiple conducting wires, and wherein lead is drawn at the different parts of cable.

Fig. 2 is the upward view of molded cabling starting point.

Fig. 3 is the sectional view of molded cabling.

Fig. 4 represents to hold the mould of a molded cabling.

What Fig. 5 described is to produce the mould that molded cabling of the present invention is used.

Referring to accompanying drawing.Fig. 1 has described the principal character of molded cabling of the present invention to preferred embodiment shown in Figure 3.Molded cabling 10 of the present invention contains multiple conducting wires 12 usually, and the plastics class combination materials 28 with braiding between lead keeps determining deviation relation.

The preferred embodiment and the most preferred embodiment thereof of molded cabling of the present invention are described now, and production method.Yet, should be appreciated that the most preferred embodiment of Miao Shuing refers to describing method herein, rather than a kind of restriction.The scope of the invention comprises that all contain the improvement of main design feature.

Can contain in the molded braiding cabling 10 of the present invention and have only three leads, until almost unlimited root lead.Usually, included lead is many more, and Weaving pattern is just complicated more, and is all the more so during particularly if desired more than the structure more than one deck.Lead 12 can refer to 14, the second leads 16 of first lead usually, until last root lead 18.Lead 12 becomes spacing relation each other, and plastics class combination materials 24 and lead 12 usefulness Weaving patterns 30 weavings are together.Plastics class combination materials 24 is a kind of molding combination materials in the present embodiment.

For purpose of description, the Weaving pattern 30 of plastics class combination materials can be described as a fillet 28 of plastics class combination materials 24.Yet in this preferred embodiment, fillet 28 is actually such formation, promptly a kind of thawing molding compounds is injected in the mould, almost forms Weaving pattern 30 along whole length simultaneously.At first, plastics compounds 24 forms an initiating terminal at initiating terminal 20 places of near-lying mode system braid 10 around lead 12.This makes the line end 20 of lead 12 become spacing relation each other.Fillet 28 weaves on first lead 14 then, and braiding below second lead 16 again weaves above the lead at the 3rd again, and this Weaving pattern is performed until last root lead 18 is included.Fillet 28 is woven on the lead 12 with opposite direction around last root lead 18 then, back be woven on first lead 14, thereby lead with spacing relation braiding and tighten together.Weaving pattern repeats final position 32.Fillet 28 forms one around all leads 12 and finishes end 34 then, and lead 12 is in proximal points 32 place's terminations.

Initiating terminal 26 and finish end 34 all leads are tightened together keeps the certain spacing relation mutually at the starting point and the destination county of molded cabling 10.If do not have initiating terminal 26 and finish end 34, lead 12 slides to first braid over braid of plastics compounds with side direction, thereby has weakened the structure of these position molded cablings.

In fact the structure that adopts molded cabling 10 of the present invention and production method to make does not have any restriction.As described in Fig. 1 and Fig. 4, there are an initiating terminal 20 and three to finish end 22.The form of the quantity of the practical structures of cable, initiating terminal and end end and position, termination is decided by practical application.Description here and example also do not mean that it is restriction to scope of the present invention and application.Under arbitrary given application scenario, a plurality of ends of incoming cables and leading-out terminal can be arranged.In addition, a plurality of cables in the table apparatus can be configured to have different structures.

Molded cabling 10 of the present invention has many remarkable advantages.This comprises: greater flexibility, and weight saving, the maintenanceability in the cable has only been enumerated the most tangible example here.Because lead is not fastened, and all is fastened in the shell, so no matter be that wrap up or molded, lead has bigger freedom of motion.Lead 12 can slide between the arrowband in the Weaving pattern 30 28.This has greater flexibility with regard to making cable than the cable of other types of the prior art.

Because plastic materials has only covered the only about half of outer surface of lead 12, and is not filled in the space between the lead, so only need half or material still less.Also because only used half of materials, so weight has alleviated greatly.

Can in molded cabling 10, keep in repair lead 12.This is because the lead 12 in the cabling 10 can be free to slide in Weaving pattern 30, and can observe the cause of the outer surface of lead about 1/2nd.So, can easily observe and enter the problem region.Solid conductor (perhaps multiple conducting wires) can be extracted from Weaving pattern 30, and puts back to, and can not destroy the integrality of cable.This can not accomplish in the known cabling of prior art usually.Usually, the lead that the inside is comprised could be observed and contact to cable jacket of the prior art must after peeling off or isolating out.So, as a rule, be to change cable, rather than recovery cable.

Just as noted above, plastics class combination materials 24 is to be a kind of molding combination materials in this most preferred embodiment.As shown in Figure 4, in this preferred embodiment, Weaving pattern 30 is to form with injection molding technology.Main inlet is represented with label 36.The molding compounds that melts is injected in the main inlet 36, and flows into inlet 40 one by one by injecting groove 38.In preferred embodiment as shown in the figure, each inlet 40 forms two plastics compounds arrowbands 28.When designing all inlets 40, should be injected into molding compounds in the Weaving pattern 30 simultaneously.So, should almost form all arrowbands 28 simultaneously.

The excessive molding compounds that injects from inlet flows out by the outlet 42 of molded cabling 10 reverse side.Unless have excessive moulding material to flow out, otherwise can not do complete molded cabling 10 from all outlet ports 42.So just can guarantee before mould 50 is removed, to be completed into all arrowbands 28.

First step for preparing molded cabling 10 of the present invention is a preparation mould 50, as shown in Figure 5.Mould 50 can prepare with any method well known in the prior art.Mould 50 should have notch, Weaving pattern 30, injection 40 and outlet 42.Groove 52 should be corresponding with size, quantity and the desired structure of lead 12, the final cable 10 that will produce.Mould 50 also should have certain inlet 36, is used for receiving molding compounds.In originally than embodiment, main inlet 36 is used for guiding injection groove 38.Inlet 40 length directions that link to each other with injection groove 38 are used for presenting injection material to the each point of Weaving pattern 30.Usually, multiple spot is corresponding with other structures of Weaving pattern.Also have open area 44 on the initiating terminal 26, finish to also have open area 46 on the end 34.

After mould was finished, what next step will be done was that lead 12 is installed in the groove 52, and finished the assembling of mould 52 and lead 12, thereby was ready to the injection of molding compounds.

Use a kind of any injection technology well known in the prior art then, the molding compounds that melts is injected in the main inlet 36.Molding compounds flows into inlet 40 one by one by injecting groove 38, and flows into Weaving pattern 30.In case Weaving pattern 30 is filled up fully, excessive molding compound just flows out from exporting 42.

Then, decide on concrete molding compounds, available a kind of curing process makes the appropriate location of molding compounds and solidifies.After appropriate the curing, mould 50 can be removed, and what stay is exactly molded cabling 10.Remove excessive compound and flash thereof, thereby finish finished product.

After describing the present invention in detail, the technical staff in the industry will be understood that, under the situation that does not depart from foregoing invention spirit, can improve the present invention.

So, describe above should only not being limited in the scope of the invention and the scope of the preferable enforcement described in.And scope of the present invention should be as the criterion with claims hereinafter.
