Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The first embodiment is as follows: referring to fig. 1, a shielded cable, including electric wire and skeleton 3, a serial communication port, the electric wire includes conductor 1 and insulating layer 2, insulating layer 2 wraps up in the outside of conductor 1, the material of skeleton 3 is PPS plastics or ABS plastics, there are a plurality of holding chambeies in the skeleton 3, the electric wire is inserted in the holding chamber of skeleton 3, the electric wire root is separately, the possibility of short circuit has been reduced, the outside parcel of skeleton 3 has around covering 4, it has stopping 5 all to fill between covering 4 and the skeleton 3 and between the inner wall of skeleton 3 and insulating layer 2, stopping 5 is polypropylene, non-woven fabrics or glass fiber, it has woven shielding layer 6 to wrap up around the outside of covering 4, the material of woven shielding layer 6 is pure copper or tinned copper, be provided with earth connection 7 around covering 4 and between woven shielding layer 6, the outside parcel of woven shielding layer 6 has oversheath 8.

In this embodiment, the cross section in the holding chamber in the skeleton 3 is regular hexagon, when guaranteeing cable strength, and cable inner space utilization is higher, and the cable cross section is less.

Example two: referring to fig. 2, a shielded cable comprises a wire and a framework 3, and is characterized in that the wire comprises a conductor 1 and an insulating layer 2, the insulating layer 2 is wrapped outside the conductor 1, the framework 3 is made of PPS plastic or ABS plastic, a plurality of accommodating cavities are formed in the framework 3, the wire is inserted into the accommodating cavities of the framework 3, the electric wire root is separately, the possibility of short circuit has been reduced, the outside parcel of skeleton 3 has around covering 4, it has stopping 5 all to fill between covering 4 and skeleton 3 and between the inner wall of skeleton 3 and the insulating layer 2, stopping 5 is polypropylene, non-woven fabrics or glass fiber, it has woven shield 6 to wrap around the outside parcel of covering 4, the material of woven shield 6 is pure copper or tinned copper, be provided with earth connection 7 around covering 4 and between woven shield 6, the outside parcel of woven shield 6 has oversheath 8.

In this embodiment, the cross section of the accommodating cavity in the framework 3 is regular triangle, and the stability of the framework 3 is higher than that of the first embodiment, so that the strength of the cable is higher than that of the first embodiment.
