Abstract

The utility model relates to a multi-colour conducting wire. The utility model is provided with a plurality of conducting wires, and the inner parts of the conducting wires are provided with metal cores, the outer part of each metal cores is respectively coated with PVC layers with different colors, and the outer part of each layer which is provided with the PVC layers with different colors can be respectively coated with the transparent PVC layers with molds; connecting parts are formed between every two adjacent transparent PVC layers. The utility model can discriminate the different polarities of sinal wires by taking advantage of the PVC layers with different colors, the utility model can be produced with large amount by the molds, and the appearance of the utility model is beautiful.

Description

Multi-colour conducting wire

The utility model relates to a kind of Multi-colour conducting wire, specifically belongs to PVC (polyvinyl chloride) layer that can utilize various different colours and forms the signal line that can supply the difference opposed polarity.

The utilization rate of lead is quite frequent now, especially uses more frequently on computer industry or household electric appliances, and signal line of especially using with transmission signal on using or the horn wire used with sound equipment are in the majority.

Yet, discuss with the lead of general traditional type, mostly be homochromy (black) lead greatly, again with the difference of the joint of different colours as opposed polarity, its shortcoming is that color is than torpescence, and then do not see polarity if do not see joint, its inconvenience is arranged in the use, it and for example shown in Fig. 4 another kind of conventional wires, it can be the horn wire that a kind of sound equipment is used, it mainly is to have metal-cored 60 in inside, external packets in metal-cored 60 is covered with suitable thickness and has same color PVC (polyvinyl chloride) layer 61 of (as for red), then form connecting portion 62 between the adjacent two PVC layers 61, in order to distinguish the different polarity of lead, in the outside of a PVC layer 61 wherein coated with the PVC layer 63 (as being black) of one deck and aforementioned PVC layer 61 different colours, so can utilize the different different polarity of color differentiating lead, but, above-mentioned structure but have as after shortcoming remain to be improved:

(1) because red PVC layer 61 is an extrusion molding, and because the different colours after extruding is followed the situation that there is batch mixing at the place, so outward appearance is smooth inadequately, influence exterior appearance, and because of after need finish PVC layer 61, reshaping PVC layer 63, so process velocity is slower, not satisfactory.

(2) color of lead can be restricted: when the color that is covered in outside PVC layer 63 when more shallow, the PVC layer 61 that then inside can't be had color covers really, thereby the color of two different conductors can't be made a distinction really, thereby the color of lead is restricted.

A kind of traditional lead (as shown in Figure 5) is arranged in addition, its mainly be have several with spacing distance arranged side by side metal-cored 64, be coated with the PVC layer 65 of different colours respectively in each outside of metal-cored 64, between each adjacent PVC layer 65 then with supersonic mode in addition hot melt form, but with the lead of hot melt fusing mode gained have as after shortcoming:

With the made lead of hot melting mode, because in hot melt when operation, is because of length and the restriction of heat welded time, so process velocity is quite slow, thereby have can't mass-produced shortcoming, and the structural strength at hot melt place is relatively poor easily to be crushed by external force, thereby has the improper problem that gets loose of generation between the lead that makes.

Therefore, above-mentioned traditional type conductor structure exists not enough in producing use, and the necessity that is improved is arranged.

Main purpose of the present utility model is to overcome the deficiencies in the prior art, provides a kind of PVC layer that utilizes various different colours to distinguish the Multi-colour conducting wire of signal line opposed polarity.

The purpose of this utility model is achieved in that a kind of Multi-colour conducting wire, includes the metal-cored lead of a plurality of tools, is coated with the PVC layer with different colours respectively in each metal-cored outside, wherein:

The outside that each lead has the PVC layer of different colours respectively can coat transparent PVC layer by mould, is formed with connecting portion respectively between the two adjacent transparent PVC layers.

The utlity model has following advantage:

(1) can produce in a large number: the utility model uses roller 40, mould 41, tank 50 etc. can reach fast and mass-produced purpose when producing.

(2) different polarity be distinguished, be discerned to the lead of opposed polarity can easily by the PVC layer of different colours.

(3) inside of the present utility model has metal-cored 10 and PVC layer 20 with color, can utilize mould 41 that the outside of PVC layer 20 is coated transparent PVC layer 30 apace, and quite smooth after coating, thereby has preferable exterior appearance.

(4) be one-body molded between connecting portion 31 of the present utility model and the transparent PVC layer 30, do not need as conventional wires, to make hot melt,, and be not easy to the advantage that the generation of lead place gets loose so it is preferable to have structural strength with mould.

Accompanying drawing below in conjunction with embodiment further specifies specific structural features of the present utility model and purpose.

Brief Description Of Drawings:

Fig. 1 is the stereo appearance figure of an embodiment of Multi-colour conducting wire of the present utility model;

Fig. 2 is the schematic diagram of Fig. 1 when procedure for processing;

Fig. 3 be Fig. 1 Multi-colour conducting wire in conjunction with cutaway view Amplified image;

Fig. 4 be first kind of conventional wires in conjunction with cutaway view Amplified image;

Fig. 5 be second kind of conventional wires in conjunction with cutaway view Amplified image.

The utility model is a kind of Multi-colour conducting wire (shown in Fig. 1,3).The utility model includes: the lead of a plurality of inner tools metal-cored 10, be coated with PVC (polyvinyl chloride) layer 20 respectively with different colours in each outside of metal-cored 10, each layer has the different outsides of the PVC layer 20 of looks frequently and is coated with respectively between the adjacent transparent PVC layer 30 of transparent PVC layer 30, two and is formed with connecting portion 31 respectively.

For another example shown in Fig. 2,3, be the schematic diagram of the utility model when procedure for processing, the utility model is to utilize inside to have metal-cored 10 and have the PVC layer 20 of different colours respectively, each gang PVC layer 20 can transfer in the mould 41 via number roller 40, to keep the elastic strength of lead, and the raw material of transparent PVC can be added by the top of mould 41 in the mould 41, and can be in the external packets of each PVC layer 20 coated with transparent PVC layer 30, again external packets is covered with PVC layer 20 behind the transparent PVC layer 30 via tank 50 coolings after, re-use several rollers 40 and collected.
