Abstract
The utility model winding displacement comprises an insulation body and a plurality of conductors arranged inside the insulation body. The conductors is arranged inside the insulation body at least in three layers, wherein the width of the a middle layer is less than or equal to the width of two neighboring layer. Compared with prior art, the utility model winding displacement is provided with multi-layer conductors inside the insulation body which can transmit high-frequency signals. The model, of a low price and of high performance, is suitable for mass production which conform to rapid developing tendency of electronic industry in information age.
Description
[technical field]
The utility model relates to a kind of winding displacement.
[background technology]
At present, industry is the various in style of holding wire in order to transmission signals, difference according to institute's transmission signals, holding wire is also neither identical, our common several holding wires have twisted-pair cable at present, coaxial cable, the winding displacements of signal etc. are organized in optical cable and transmission simultaneously more, wherein, the twisted-pair cable low price, but frequency transmission signal is lower, when frequency is higher, between the holding wire because there is not a corresponding shielding measure, the signal transmission is subjected to very serious disturbance between adjacent holding wire and make, and the accuracy of signal transmission descends, and transmission speed is also restricted greatly, certainly, comparatively speaking, the superior performance of coaxial cable and optical cable many promptly can transmitting high-frequency signal, transmission speed is very fast again, but expensive again many of price.
Develop rapidly along with the IT industry, the speed of data is more and more faster, capacity is increasing, frequency is more and more higher, therefore also more and more harsher to the requirement of transport vehicle, the carrier that winding displacement transmits simultaneously as multi-group data, both satisfied the big capacity of data, the transmission of two-forty, solved the interference problems such as cross-talk of high-frequency transmission again to a certain extent, still, present existing winding displacement wants one only to adopt signal terminal and the staggered form of ground wire terminal simply to eliminate the interference of damask signal, want one with screen holding wire to be surrounded fully and shields with regard to the form that adopts similar coaxial line, the former, shield effectiveness is relatively poor, still interference problem can occur in transmitting high-frequency signal, the latter's shield effectiveness is fine, and the divisor performance is also very superior, but involves great expense, and is unfavorable for a large amount of production utilizations.
Therefore, be necessary to design a kind of novel winding displacement, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide a kind of winding displacement, and it is simple in structure, and effectively transmitting high-frequency signal, and sexual valence height is convenient to large batch of production and processing.
In order to reach above-mentioned creation purpose, the utility model winding displacement, comprise insulating body and place the interior several conducting of insulating body, described electric conductor is three layers of arrangement at least in insulating body, and wherein its width of the electric conductor in intermediate layer is not more than the width of adjacent two layers electric conductor.
Compared with prior art, the utility model winding displacement, by in insulating body, being installed with the multilayer conductive body, both can transmitting high-frequency signal, price is cheap again, and the cost performance height is convenient to large batch of production and processing, meets the trend that the information age electron trade develops rapidly.
[description of drawings]
Fig. 1 is the stereogram of the utility model winding displacement;
Fig. 2 is the transverse sectional view of the through hole of winding displacement shown in Figure 1;
Fig. 3 is a part enlarged drawing in the winding displacement cross circular section shown in Figure 2;
[embodiment]
Below in conjunction with the drawings and specific embodiments the utility model winding displacement is described further.
Please refer to Fig. 1 to shown in Figure 3, the utility model winding displacement comprises insulating body 10 and several conducting 20, and described electric conductor 20 layerings are located in this insulating body 10.
Described electric conductor 20 comprises signal transmission body 201 and shield 203, when being installed with in insulating body 10,20 one-tenth three layers of arrangements of electric conductor, wherein, signal transmission body 201 is positioned at the center, its upper strata and lower floor are all the shield 203 of width greater than signal transmission body 201 itself, its left and right sides is level height other two shields 203 identical with it, be the center promptly with signal transmission body 201, its periphery be provided with four grounded shield 203 up and down, and have part to overlap between two-layer up and down shield and intermediate layer shield.
In addition, described insulating body 10 is provided with some through holes 30, part overlapping place of two-layer shield and intermediate layer shield about this through hole 30 is located at, be provided with the conductor 301 that connects three layers of shield in its through hole 30, so, four shields 203 of the periphery of each signal transmission body 201 are provided with two through holes 30, it is with described four shield 203 conductings, make it to form a ring-type integral body that electrically conducts, this through hole 30 can be provided with row's (not icon) by an end at the utility model winding displacement, also can be to be provided with many rows (as shown in Figure 1), the conducting effect that the shield of many row's ground connection is set certainly can be better, can decide according to needs in the production.
By electromagnetic principle as can be known: around the signal transmission body is the earth shield body, when signal transmitted, electromagnetic field was limited between signal transmission body and the shield, and its decay is little, and the cross-talk between the signal transmission body of signal transmission body and vicinity is also little, helps the transmission of high-frequency signal.
Share the shield 203 in an intermediate layer between per two signals transmission of the utility model winding displacement body, thereby reduced the quantity of shield on the whole, dwindled the volume of winding displacement, reduced cost, certainly its signal transmission body 201 can be one, also can be two or more signal transmission bodies of the same signal source signal of transmission.From whole winding displacement, when production and processing, this winding displacement can be installed with in one deck insulating body 10 by electric conductor 20, perhaps also can be installed with in two or more insulating bodies (not icon) and then processing connects as one.
Therefore its processing of the utility model winding displacement is simple, and cost is lower, and signal transmission quality is also higher relatively, is convenient to large batch of production and processing.
