Description

Core wire group and the cable for using the core wire group

[technical field]

The utility model is in relation to a kind of core wire group and using the cable of the core wire group, and espespecially one kind is used for transmission high-frequency signal High speed signal cable.

[background technique]

As the development of electronics technology product is universal, high speed signal cable is widely applied as a kind of tool for transmitting signal In the connection of the electronic equipments such as household electrical appliances, instrument and meter, electric tool and automation equipment.However in signals transmission, Especially during high frequency signal transmission, cable need to often use shielding construction easily by the interference of external electromagnetic signal Design can prevent the leakage of transmission signal to eliminate or reduce the interference of external electromagnetic field.

Thus, it is necessary to which providing a kind of has stronger electromagnetism interference performance, stable signal transmission, reliable and be simple to manufacture Shield cable.

[utility model content]

It, should the main purpose of the utility model is to provide a kind of core wire group and using the high speed signal cable of the core wire group High speed signal cable uses a kind of completely enclosed shielding construction to improve the shield effectiveness of electromagnetism interference, and then ensures signal The reliability of transmission.

To achieve the above object, the utility model can use following technical scheme: a kind of core wire group comprising Yi Duixin Shielded layer, two ground lines being located on the outside of shielded layer on the outside of number line, cladding signal wire and it is coated on shielded layer and ground line The sheath in outside, the signal wire include signal wire conductor and the insulating layer for coating signal wire conductor, the axis of the ground line On the same line with the axis of signal wire, the shielded layer only has one layer.

To achieve the above object, the utility model can use a kind of following technical scheme: cable comprising several described Core wire group, the fixing layer being coated on the outside of the core wire group, the external shielding layer being coated on the outside of the fixing layer and it is coated on institute The cable cover of external shielding layer is stated, a pair of core wire group stacks arrangement in fixing layer.

Compared with prior art, the utility model has the following beneficial effects: the electrical characteristic performance of high speed signal cable It improves, there is the high speed data transfer ability of the signal frequency greater than 20GHz.Shielded layer is completely covered by insulating layer, to make From outside electromagnetic interference when the signal wire conductor propagation signal of signal wire, while the signal on signal wire conductor can also be prevented Leakage, and then ensure the reliability of signal transmission.

[Detailed description of the invention]

Fig. 2 is the cross-sectional view of the first embodiment of cable.

Fig. 3 is the cross-sectional view of the second embodiment of cable.

[specific embodiment]

Refering to Figure 1, being the embodiment of the utility model core wire group 1.The core wire group 1 since center outward according to The secondary sheath 14 equipped with signal wire 11, the shielded layer 13 of cladding signal wire 11, ground line 12 and cladding ground line and shielded layer, Wherein signal wire 11 is arranged in parallel, and the shielded layer 13 is wrapped in the outside of signal wire 11, two wound on the signal wire 11 The distance between section shielded layer is known as pitch, and pitch is smaller, then what is wound is closer.The shielded layer 13 is made of metal foil, Electromagnetic shielding performance can be improved by changing the size of pitch, the signal wire 11 includes signal wire conductor 111 and insulating layer 112.The signal wire conductor 111 is made of silver-plated copper conductor, is used for transmission high-frequency signal.The insulating layer 112 coats signal Line conductor 111 separates signal wire conductor 111 and the external world.The ground line 12 is made of metallic conductor, two ground lines 12 Point-blank, the ground line 12 is electrically connected the axis of axis and two signal wires 11 with the shielded layer 13.

On the basis of previous embodiment, the first embodiment of the utility model cable 2 is proposed.The cable 2 includes The core wire group 21 of previous embodiment, the fixing layer 22 of the cladding core wire group 21, the cladding fixing layer 22 external shielding layer 23, And the cable cover 24 of the cladding external shielding layer.The core wire group 21 is successively arranged signal wire 211, cladding outward since center Shielded layer 213, ground line 212 and the cladding of signal wire 211 are grounded and the sheath 214 of shielded layer.The signal wire 211 wraps It includes signal wire conductor 2111 and is coated on the insulating layer 2112 in 2111 outside of signal wire conductor.The signal wire conductor 2111 is by plating Silver-bearing copper conductor is made, and is used for transmission high-frequency signal.The ground line 212 is set to be electrically connected with shielded layer 213.

On the basis of previous embodiment, second of embodiment of the utility model cable 3 is proposed.The cable 3 includes The core wire group 31 of previous embodiment, the fixing layer 32 for coating the core wire group 31 wrap around arrangement around the fixing layer 32 Outer fixing layer 33 around several core wire groups 31 of arrangement of several core wire groups 31, cladding, the cladding outer fixation The external shielding layer 34 of layer 33 and the cable cover 35 of the cladding external shielding layer 34.The core wire group 31 since center outward according to The secondary sheath equipped with signal wire 311, the shielded layer 313 of cladding signal wire 311, ground line 312 and cladding ground line and shielded layer 314.The signal wire 311 includes signal wire conductor 3111 and the insulating layer 3112 for being coated on 3111 outside of signal wire conductor.Institute It states signal wire conductor 3111 to be made of silver-plated copper conductor, is used for transmission high-frequency signal.The ground line 312 is set and shielded layer 313 are electrically connected.Several core wire groups 31 in the fixing layer 32 stack arrangement.

It is understood, however, that although before description in refer to the utility model many features and advantage, including The details of some structure and functions, but the disclosure is merely illustrative, and many details can change, especially appended In component shape, size and arrangement in concept represented by the broad sense general sense of the term of claim statement.
