Abstract
In order to solve the problem of poor electromagnetic compatibility effect in the prior art, the invention discloses a homemade shielded cable accessory EMC (electromagnetic compatibility) thin-film assembly of military equipment, and belongs to the technical field of electromagnetic compatibility. Aluminum conductive layers are plated on the two surfaces of a polyethylene film substrate; ferrite magnetic material layers are electrically deposited on the aluminum conductive layers on the two surfaces respectively; and the electrically deposited ferrite magnetic material layers are formed by 1/2 area from the top down of one of the electrically-deposited ferrite magnetic material layers on the two surfaces and by 1/2 area from the bottom up of the other electrically-deposited ferrite magnetic material layer on the two surfaces so as to form a closed electrical space and a closed magnetic space on the outer layer of a shielded cable. According to the homemade shielded cable accessory EMC thin-film assembly of military equipment, the electrical shielding performance and the magnetic shielding performance of the homemade shielded cable are improved; the electromagnetic interference resistance capability of the military equipment is improved; the reliability of the military equipment is enhanced; and extremely high practical value is realized.
Description
Technical field
The invention belongs to the electromagnetic compatibility technology field, be specifically related to a kind of military equipment self-control shielded type cable annex EMC film assembly.
Background technology
In military electronics equipment, the photoelectric measurement equipment of various models, radar and remote sensing equipment, EW Equipment and subsystem thereof, the EMC performance design processing mode of subsystem, all be simple traditional shielded type cable annex mounting process that adopts: the cable outer shielding layer adopts metal net, this shielded type cable is the shielding measure of taking for electric field, and for the larger magnetic field of near-field energy, this technological design electromagnetic compatibility (EMC) weak effect, make military equipment poor anti jamming capability in debugging and use procedure, crosstalk, disturb mutually and happen occasionally, this has directly had influence on the functional reliability of military equipment and the requirement that its realization develops rapidly.
Summary of the invention
For the problem of the electromagnetic compatibility weak effect that overcomes prior art, the invention provides a kind of military equipment self-control shielded type cable annex EMC film assembly.
Technical scheme of the present invention is:
A kind of military equipment self-control shielded type cable annex EMC film assembly, the conductive layer of aluminizing on the two sides of polyethylene film base material, at two sides aluminium conductive layer Electrodeposition Bath of Iron oxysome magnetic material layer respectively, and the Electrodeposition Bath of Iron oxysome magnetic material layer on two sides is set to respectively one side, and 1/2nd area, another side are 1/2nd area from bottom to up from top to bottom.
Beneficial effect of the present invention: a kind of military equipment self-control of the present invention shielded type cable annex EMC film assembly, form shielded cable and pricked outer sealing electricity, the magnetic space, and can conveniently transform the interface device of existing military equipment, improve self-control shielded type cable electricity, magnetic shield performance, the GJB-151A that greatly improves between various military equipments and its subsystem detects qualification rate, Effective Raise conduction emission (CE), radiation-emitting (RE), conducted susceptibility (CS), radiated susceptibility (RS) characteristic index, improve the anti-electromagnetic interference capability of military equipment, strengthened the reliability of military equipment; Owing to having adopted the polyethylene base material, the three anti-temperature characterisitics that reach are given prominence to, and can adapt to various adverse circumstances, and are soft, light, bending resistance is strong, and assembling, replacing are rapidly, and be simple to operate, failure rate is low, work is flexible, and the reliability of increasing work efficiency and working has high practical value.
Description of drawings
Fig. 1 is the structural representation of a kind of military equipment self-control of the present invention shielded type cable annex electromagnetic compatibility film assembly.
Among the figure: 1, polyethylene film base material, 2, the conductive layer of aluminizing, 3, Electrodeposition Bath of Iron oxysome magnetic material layer.
Embodiment
As shown in Figure 1, a kind of military equipment self-control shielded type cable annex EMC film assembly, the conductive layer 2 of aluminizing on the two sides of polyethylene film base material 1, at two sides aluminium conductive layer 2 Electrodeposition Bath of Iron oxysome magnetic material layers 3 respectively, and the Electrodeposition Bath of Iron oxysome magnetic material layer 3 on two sides is respectively one side, and 1/2nd area, another side are 1/2nd area from bottom to up from top to bottom.According to the difference that self-control shielded type cable characteristic index requires, can select magnetic material and the electro-deposition thickness of heterogeneity.
Application of the present invention: make the present invention by oneself shielded type cable annex EMC film assembly and be tailored into the wide take-up strap of 25mm, uniform winding is pricked outer at the self-control cable, the two-layer overlapped winding of the conductive layer of aluminizing, and every layer of overlapped width is 1/2 of take-up strap width.Carry out again the outer fence operation of cable at the film assembly skin.
Operation principle explanation of the present invention: the present invention makes shielded type cable annex EMC film assembly by oneself and is installed on the self-control shielded cable bundle, when disturbing pulse occurs, cable is pricked will produce larger disturbing magnetic field, consume most magnetic field energys by the magnetizing mediums on the EMC film assembly; And when producing the electric field radiation interference on the cable, the conductive layer of aluminizing on the EMC film assembly has played again the effect of electric screen layer, thereby plays anti-electric field interference effect.Since formed electricity, the magnetic space layer of sealing at cable outer layer, also quite desirable for the shield effectiveness that electricity, magnetic radiation disturb.
