Abstract
The utility model provides a composite shielding net for an electric cable, which adopts a composite shielding structure which can twist, wind and fix a cable, i.e. a layered shielding net which is formed by a metal foil and an insulating adhesive tape directly and wholly packs and binds the electric cable, therefore, the composite shielding net not only can realize the reliable shielding according to the correlative safety standard, but also guarantees the good radial intensity and rigidity of the electric cable, and is suitable for the connection and the fixation of the electric cable relative to a movement part. The composite shielding net mainly comprises at least one layer of metal foil which is wound at the outer layer of the electric cable, an insulating adhesive tape which is bonded at the outer layer of the metal foil, and a pair of nylon hasps which are arranged at the two ends of the insulating adhesive tape. According to the installation requirement and the different fixation parts of a railway vehicle-mounted electric device, the electric cables can be connected with each other according to the use requirement, and the composite shielding net and the electric cables are tightly crimpled and wound with each other and are locked with the nylon hasps.
Description
Technical field
The utility model is a kind of cable composite shielding net that is used for rail vehicle onboard electrical device electromagnetic protection, belongs to machine-building and electric field.
Background technology
Home and abroad high-speed track vehicle adopts driven by power at large at present, corresponding car load Electro Magnetic Compatibility need reach the EN50121 standard, wherein the electromagnetic interference main path that produced of onboard electrical device is radiation and conduction dual mode, adopts rationally, effectively filtering is the main path that solves this type of electromagnetic compatibility problem with shielding.
Because the electric current of the linear electric motors cable of high-speed track vehicle and AC power cable is bigger, for around the influence on system operation of other electric equipments bigger, must take good cable shield mode.Existing usually cable be inserted in the aluminum pipe and shield for being connected and fixed the position, but for the cable at relative motion position then because twisted wire just can adopt shielded type cable later on, therefore cause cable size big, be not easy bending and be connected and fixed.
If directly adopt the bare wire structure, can cause the cable at this position to produce bigger electromagnetic interference again.
The utility model content
The utility model relates to a kind of cable composite shielding net, its purpose of design is to address the above problem and adopts the composite shielding structure that can twine and play fixation at twisted wire later on, the laminated shield net that is about to the formation of tinsel and insulating tape is directly lived whole cable ground parcel and binding, can either realize shielding reliably by the associated safety standard, guarantee that again cable possesses good warp-wise strength and stiffness, the cable at suitable relative motion position connects and is fixing.
Another purpose of design is, realizes a kind of electromagnetic shielding component that on-site cable connects and overhauls that is adapted to, and can easily gauze screen be carried out ground connection disposal simultaneously.
For realizing above-mentioned purpose of design, described cable will include with the composite shielding host:
Be used to be wrapped in the tinsel of one deck at least of cable outer layer,
Be attached to the outer field insulating tape of tinsel, and,
Be provided with a pair of velcro at the two ends of insulating tape.
As above-mentioned basic scheme, require and the different fixing position according to rail vehicle onboard electrical Unit Installation, can earlier cable be connected by instructions for use, described then composite shielding net and cable twine tightly, finally tighten locking with velcro.
The composite shielding net is wrapped in cable outer layer, can carries out electromagnetic shielding, not only can prevent the electromagnetic interference of adjacent large power, electrically device of air by tinsel, and simple to operate, be easy to overhaul at electric device and cable.
For improving effectiveness and control manufacturing cost further, described tinsel can be selected the thin layer aluminium foil for use.
For guaranteeing the ground connection treatment effect of composite shielding net, can on aluminium foil, connect an establishment earth connection.
For the winding stability of improving cable and composite shielding net with prevent to cause cable fault, can be provided with cable protection rubber and nylon cable tie at the skin of insulating tape because of tying up tension.
As above content, advantage and the beneficial effect that the utlity model has are:
1, adopts the composite shielding net after twisted wire, directly whole cable ground to be wrapped, therefore can realize safely, shield reliably.
2, the composite shielding netting gear is equipped with good warp-wise strength and stiffness, is suitable for the connection of relative motion position cable.
3, be adapted to on-site cable connection and maintenance, can easily gauze screen be carried out ground connection disposal simultaneously.
Description of drawings
Now with explanation the utility model is done further explanation in conjunction with the following drawings.
Fig. 1 is the cross-sectional view of described cable with the composite shielding net;
Fig. 2 is a track car body local cable connection diagram;
Fig. 3 is that the B-B of Fig. 2 is to cut-away view;
As shown in Figure 1 to Figure 3, insulating tape 1, aluminium foil 2, velcro 3, establishment earth connection 4, cable protection rubber 5, nylon cable tie 6, cable 7, motor 8, car body mount pad 9.
Embodiment
Be provided with a pair of velcro 3 at the two ends of insulating tape 1.
Connect an establishment earth connection 4 separately at the two ends of aluminium foil 2.
As shown in Figures 2 and 3, motor 8 is installed on the car body mount pad 9, and cable 7 skins of motor 8 twine and tighten locking described composite shielding net.
Composite shielding net and cable 7 twine the back and use velcro 3 to lock, and come off from cable 7 for preventing the composite shielding net, tie up at also available cable protection rubber 5 in two ends and middle part and nylon cable tie 6.
