Description

Ship LAN cable of warship

Technical field

The utility model is related to a kind of cable, and especially a kind of ship LAN cable of warship, belongs to field of cable technology.

Background technology

Need to use substantial amounts of LAN cable, the local on current naval vessel with the raising of the level of IT application, on naval vessel The material of net cable is the copper conductor polyethylene insulation pe sheath of 0.5mm2, this kind of cable be generally laid in electromagnetic environment compared with It is complex environment, therefore it is required that this kind of cable has stronger anti-electromagnetic interference capability, two-layer is generally used in the prior art Shielding construction is solved, i.e., one layer of aluminium foil layer is surrounded with outside cable conductor, and layer of metal shielding is woven with sheath Layer or other armors.

There is problems with and shortcoming in prior art：

1st, because the single core of this kind of cable is typically 0.5mm2, core is smaller, and tensile capacity is poor, and cable is typically to put On reel, the situation that workman breaks core is frequently encountered in work progress；

2nd, employ in the prior art two-layer shielding construction can effectively withstand external electromagnetic interference influence, but office Domain net cable is usually four groups of pair twist core twisted synthesizing cable cores, and the cross-talk between each core cannot be solved at all.

The content of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of ship LAN cable of warship, Can solve the problem that the problem that cable tensile property is poor, core has cross-talk in the prior art.

According to the technical scheme that the utility model is provided, the ship LAN cable of warship, including cable core, it is characterized in that： The centrally disposed cross insulation framework of the cable core, four gap locations that insulation framework is separated into are respectively provided with four groups of twisted pair wires Core, pair twist core and insulation framework it is stranded after in the wrapped polyester belt of outer layer, channelizing line is set in the outside of polyester belt, in polyester belt The wrapped aluminium foil strip in outside, channelizing line is arranged in aluminium foil strip, sheath is extruded in the outer layer of aluminium foil strip, in the outer layer of sheath The total screen layer of braiding tinned copper wire braiding；Outer jacket is extruded in the outer layer of the cable core.

Further, the pair twist core is formed by both threads core pair twist, in the outer braid tinned copper wire of pair twist core Pair twist always shields layer.

Further, the core includes conductor, in the outer layer extruded insulation layer of conductor, is plated in the outer braid of insulating barrier Tin copper wire split screen layer.

Further, the centrally disposed high intensity aramid yarn of the insulation framework.

Ship LAN cable of warship described in the utility model by the way of " split screen+total screen ", solves electricity outside core The problem of each core cross-talk in cable inside, improves the electromagnetism interference performance of cable；Cable center with high intensity aramid yarn Cross insulation framework solve the problems, such as cable not tension in the prior art, improve the tensile property of cable.

Brief description of the drawings

Fig. 1 is the structural representation of ship LAN cable of warship described in the utility model.

Description of reference numerals：Channelizing line 1, high intensity aramid yarn 2, insulation framework 3, conductor 4, insulating barrier 5, tinned copper wire point Screen layer 6, tinned copper wire pair twist always shield layer 7, polyester belt 8, aluminium foil strip 9, the total screen 11, outer jacket of sheath 10, tinned copper wire braiding 12。

Specific embodiment

With reference to specific accompanying drawing, the utility model is described in further detail.

As shown in Figure 1：Ship LAN cable of warship described in the utility model includes cable core, the centrally disposed cross of cable core Insulation framework 3, four gap locations that insulation framework 3 is separated into are respectively provided with four groups of pair twist cores, pair twist core and insulation framework 3 In the wrapped polyester belt 8 of outer layer after stranded, channelizing line 1 is set in the outside of polyester belt 8, in the wrapped aluminium foil strip in the outside of polyester belt 8 9, channelizing line 1 is arranged in aluminium foil strip 9, and sheath 10 is extruded in the outer layer of aluminium foil strip 9, tin plating in the outer braid of sheath 10 Proof copper-wire braided always shields layer 11；Outer jacket 12 is extruded in the outer layer of the cable core.

The pair twist core is made up of both threads core by the way of pair twist, in the outer braid tinned copper wire of pair twist core Pair twist always shields layer 7；The core includes conductor 4, in the outer layer extruded insulation layer 5 of conductor 4, is plated in the outer braid of insulating barrier 5 Tin copper wire split screen layer 6.

The centrally disposed high intensity aramid yarn 2 of the insulation framework 3.

The operation principle of ship LAN cable of warship described in the utility model：

1st, tensile property is improved：The centrally disposed cross insulation framework of LAN cable, its effect is for supporting Cable conductor, it is ensured that cable roundness, while also separate each group core, it is convenient to install.

Cross insulation framework by extruded outside an aramid yarn cross insulation be made, cross sets in gap Four groups of pair twist cores are put, because four groups of pair twist cores are stranded, twisted pair wire around cross insulation framework in finished cable Physical length after core launches is more long than the length of cross insulation framework, therefore during dragging, main stress point is concentrated on On cruciform skeleton, cable pair twist core is protected.

2nd, solve the problems, such as internal cross-talk and improve electromagnetic interference performance：

The shielding of the pair twist core of cable is to weave tin-coated copper outside each core using in " split screen+total screen " structure, i.e. cable Braiding split screen, count is 90%, and one layer of pair twist split screen is woven outside pair twist core, and count is 90%, and this Rotating fields can Other cores are not disturbed with the electromagnetic wave for each core of cable is produced, cross-talk between each core is solved the problems, such as；Exist in addition There are two-layer shielding construction, i.e. aluminium foil strip and metal knitted total screen outside cable core, this double-layer structure can prevent external electromagnetic interference from entering Enter inside cable, strengthen the anti-electromagnetic interference capability of cable.
