Beneficial effect：This utility model has the advantages that：

(1) compared with prior art, the master core in this utility model is used for transmission signal, its outside setting main shield Layer, shielding interference, and after the wrapped stranding of main cables, further the total screen layer of setting increases anti-jamming effectiveness；Prior It is to be provided with subordinate line cable in the gap location of three main clues cable, the subordinate line cable of everywhere is provided with three, and the arrangement in triangle, Auxiliary screen layer is also equipped with the subordinate line core of subordinate line cable, on the one hand the auxiliary screen layer of itself eliminates part interference to subordinate line cable, uses In transmission signal, increase the intensity of signal；On the other hand it is arranged on the gap location of three main clues cable, itself can be used as screen layer Using it is ensured that the signal transmission strength of main cables is with without interruption, cable shield effect therefore of the present utility model is good, signal By force, strong antijamming capability；

(2) master core of the present utility model twists for copper wire and forms, and primary shield is the mesh shields of proof copper-wire braided Layer, both arrange the same shield effectiveness that can strengthen primary shield；Subordinate line core is that tin plated wire speed silk forms, and auxiliary screen layer is plating The mesh shields layer of stannum silk braiding, can strengthen the shield effectiveness of auxiliary screen layer；And the material of primary shield and auxiliary screen layer Matter setting different, so can interleaving shields interference signal of different nature, further enhance shield effectiveness.

Brief description

Fig. 1 is this utility model structure chart.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, the present embodiment is with this utility model Implemented under premised on technical scheme it should be understood that these embodiments are merely to illustrate this utility model rather than limit this reality With new scope.

As shown in figure 1, a kind of multifunctional amphibious detection private cable, including three main clues cable, described main cables Core 1 based on innermost layer；Master core 1 is coated with insulating barrier 2, and insulating barrier 2 is coated with primary shield 3；Primary shield 3 outsourcing It is covered with oversheath 4；Three main clues cable is filled by packed layer 5 and is passed through the wrapped stranding of lapping layer 6 in positive triangle arrangement；Described around Covering 6 is coated with waterproof layer 7, and waterproof layer 7 is coated with total screen layer 8, and total screen layer 8 is coated with oversheath 9.

It is additionally provided with subordinate line cable at 5 three adjacent segments of three main clues cable packed layer；Subordinate line cable at each adjacent segment It is provided with three, and be in equilateral triangle arrangement；Core 10 supplemented by described subordinate line cable innermost layer；Subordinate line core 10 is coated with auxiliary screen Cover layer 11, auxiliary screen layer 11 is coated with auxiliary sheath 12.
