Background technology

The connector range of application is quite extensive, is the important bridge between connecting circuit and signal, is the normal and stable critical elements of function of keeping electronic product.Along with electronic product continues towards gently, thin, short, little direction develops, the built-in system disposal ability is also more and more stronger, as image and sound optical disk in recent years, the digital multifunctional CD, the high-res Digital Television, audio-visual phone and video conference etc., these new systems are in order to allow the user can enjoy better quality, the information that its framework has all adopted the mode of total digitalization to come processed voice and image, the digital signal speed that is transmitted is constantly accelerated (signal can be not compressed), make relatively in the connector planning and designing also must towards " thin spaceization "; " high frequencyization " direction develops.

But high-speed transfer can produce problems such as matched impedance, cross-talk noise, transmission delay, signal attenuation, Electromagnetic Interference, causes signal of video signal or audio signals to produce noise or interruption easily when playing, and the quality of listening to or watching is greatly reduced; And cause important data data thereby loss when network communication again easily, these problems all must effectively further certainly be separated, and so can make connector improve quality and conform with the market demand.

As shown in Figure 1, the circuit board that is had for traditional its inside of existing wire and cable connector, the transmission line that all has only general simple planning, among be not preset with any good signal adjusting device, do balanced type when transmission so be used in high frequency, the anisochrouous state taking place between each pin easily, and badly influence signal transmission effect, is its major defect.

Summary of the invention

In view of this, the present utility model people is at above-mentioned disappearance further investigation improvement,

For reaching aforementioned purpose, the set a kind of choking-winding sig-nal-conditioning unit of the utility model, this sig-nal-conditioning unit comprises a circuit board, be provided with plural transmission circuit in circuit board, one side of transmission circuit is signal input part, another side is a signal output part, it is characterized in that: corresponding string is provided with plural choking-winding in the middle of this plural number transmission circuit.

The utility model also provides a kind of connector, this connector comprises a choking-winding sig-nal-conditioning unit, this sig-nal-conditioning unit comprises a circuit board, be provided with plural transmission circuit in circuit board, one side of transmission circuit is signal input part, another side is a signal output part, and should be provided with plural choking-winding by the middle corresponding string of plural number transmission circuit; The input terminal of described signal input part and connector electrically connects, and the lead-out terminal of described signal output part and connector electrically connects.

The beneficial effects of the utility model are that its structural design is simplified practicality,, can be with the balanced type transmission signals, the signal when being adjusted into etc. by the anisochrouous state can effectively improve signal transmitting quality, is particularly useful for high-frequency signal transmission.

Embodiment

After constitution content of the present utility model and other characteristics can describe in detail in the embodiment of the following conjunction with figs. of reading, and be tending towards clear.

Shown in Fig. 2～7, the set a kind of choking-winding sig-nal-conditioning unit 10 of the utility model, it comprises a circuit board 20, be provided with plural transmission circuit 21 in circuit board 20, one side of transmission circuit 21 is signal input part 22, and another side is a signal output part 23, and its improved characteristics is:

Corresponding string is provided with plural choking-winding 30 in the middle of this plural number transmission circuit 21; During enforcement, as shown in Figure 3, Figure 4, this plural number choking-winding 30 can adopt common mode choke (commom choke), and promptly a shell 31 inside are provided with two choking-windings 30 of handing over ripples, and four branch connecting pins 32 are equipped with in the outside, make it to be connected across respectively on the reserved place of two adjacent transmission circuits 21.

Please join shown in Fig. 2～4, during manufacturing, this choking-winding sig-nal-conditioning unit 10, can be directly arranged on the cable connector 40, circuit board 20 is embedded in cable connector 40 inside, output 23 with transmission circuit 21 is electric connection with connector lead-out terminal 41, and the limit input 22 in addition of transmission circuit 21 is electric connection with cable 42.During composition, 20 of circuit boards are located at cable connector 40 inside, and be provided with outside the cable connector 40 plastic material make outside over body case 43; The terminal of housing 43 also is provided with a lead-out terminal joint 44 at least.

And for example shown in Fig. 5,6, this choking-winding sig-nal-conditioning unit 10, also can be directly arranged on the connector adapter 50, circuit board 20 is embedded in connector adapter 50 inside, output 23 with transmission circuit 21 is electric connection with connector adapter lead-out terminal 51, and the limit input 22 in addition of transmission circuit 21 is electric connection with connector adapter input terminal 52.
