Problems solved by technology

[0002] In the prior art, a cable generally used for signal transmission includes a number of horizontally arranged signal wires arranged from inside to outside, a metal shield surrounding the several signal wires, and an insulating sheath surrounding the metal shield. However, sometimes when the metal shielding layer inside the cable is partially stripped off and the signal wire cannot be completely covered, the signal transmission of the cable is susceptible to external electromagnetic interference, which will also increase the characteristic impedance of the cable.

Embodiment Construction

[0015] see Figure 1 to Figure 3 The cable 1 of the present invention includes a pair of differential signal wires 11 arranged laterally, a ground wire 12, a metal shielding layer 13 covering the pair of signal wires 11 and the grounding wire 12, and a metal shielding layer 13 covering the outside of the metal shielding layer 13. An insulating outer covering layer 14 . The cable 1 also includes a sleeve 15 sheathed on the front end of the cable 1 . Each signal wire 11 includes a conductor 111 and an insulator 112 covering the conductor 111 . The front end of the cable 1 refers to the front end of the signal conductor 11 exposed on the metal shielding layer 13 , the metal shielding layer 13 exposed on the insulating outer covering layer 14 , and the insulating outer covering layer 14 .

[0016] see figure 2 , the metal shielding layer 13 does not completely cover a pair of differential signal wires 12, and one end of the pair of differential signal wires 12 is exposed outsi...

Abstract

The invention discloses a cable (1). The cable comprises a pair of transversely arranged differential signal conductors (11), metal shielding layers (13) and outer insulating coating layers (14), wherein the metal shielding layers are incompletely coated on the pair of signal conductors and outer insulating coating layers (14) are incompletely coated on the metal shielding layers; the cable also comprises a heat shrinkable bushing (15) sleeved at the front end of the cable; and the internal side of the heat shrinkable bushing is a metal layer (151) coated at the periphery of the front end of the cable.

Description

【Technical field】 [0001] The invention relates to a cable, in particular to a cable with a shielding function. 【Background technique】 [0002] In the prior art, a cable generally used for signal transmission includes a number of horizontally arranged signal wires arranged from inside to outside, a metal shield surrounding the several signal wires, and an insulating sheath surrounding the metal shield. However, sometimes when a part of the metal shielding layer inside the cable is peeled off and the signal wire cannot be completely covered, the signal transmission of the cable is susceptible to external electromagnetic interference, which will also increase the characteristic impedance of the cable. [0003] Therefore, an improved cable is needed to overcome the deficiencies of the prior art. 【Content of invention】 [0004] The purpose of the present invention is to provide a cable with a heat-shrinkable sleeve, which has a good anti-EMI effect. [0005] In order to achie...
