Abstract
The invention features the following: using metallic filament ball to fill the gap between cables or between cable and bulkhead, and filling the conducting daub and sealant at both side of the metallic filament ball; and further, the cable, conducting daub, sealant and metallic filament are loaded together into a cable pipe, and the cable pipe passes through the bulkhead and makes a sealed connection with the bulkhead.
Description
Technical field
The invention belongs to the electromagnetic compatibility field, a kind of cable penetrating technology for electromagnetic shielding cabin of more specifically saying so.
Background technology
Current continuous development owing to electronics, electric product, the usage quantity and the scope of electronics, electric product are sharply expanded.The Electro Magnetic Compatibility of electronic product, electronic equipment and electrical system becomes very distinct issues.Electromagnetic compatibility problem solves badly, and gently then equipment work can be interfered, and is heavy then at all can't operate as normal, even equipment is suffered damage.Especially for narrow space, environment that equipment is numerous, locate the life-and-death especially major issue of work of electromagnetic compatibility as the control room of telecommunications control room, computer room, boats and ships etc., must be in design, install, just consider in advance in the construction.
The operating state that wants in the electromagnetic compatibility field to reach desirable just means that various electronics, electric equipment can be independent of each other and work without interfering with each other, that is to say that each electronic equipment will improve the anti-electromagnetic interference of self and the ability of inhibition electromagnetic interference on the one hand, to not disturb other as far as possible when generally being exactly equipment work, do not disturbed yet by others; Also to create a good working environment on the other hand, reduce extraneous electromagnetic interference as far as possible to electronic equipment.
Want to reduce the extraneous electromagnetic interference interference source of must trying every possible means to take measures to block, cut off the route of transmission.Mainly contain two kinds with regard to the electromagnetic interference route of transmission: a kind of is conducted interference by power line; Another kind is exactly the electromagenetic wave radiation interference by the space coupling.
The effective method of blocking-up space electromagnetic interference is exactly with an airtight can electronic equipment to be shut up, and this theoretical method is very simple but implement and be not so easy.Imagination has an electric room on the ship, some sensitive electronic devices have been adorned in its inside, because the wall in modern its cabin of boats and ships can be used the metal material manufacturing, therefore remaining task of wanting the baffle space electromagnetic interference to propagate is exactly hole, the hole of being opened around how going to block or mask in this room.Owing in the room a large amount of electronic equipments is arranged, inevitably perforate penetrates a large amount of various cables on bulkhead.For there are multiple choices in the space between shutoff cable and the cable, between cable and the bulkhead.
A kind of is to use the filler shutoff earlier between cable and cable, cable and bulkhead, adopts aluminium foil or Copper Foil to overlay between the cable with shielding electromagnetic wave then.This method has certain effect, but the quality of its shielding action and construction has very big relation, because sheet metal overlays on impossible complete closed between the cable, always stays some holes, and these spaces can make the interference electric wave pass through smoothly in some frequency range, and enter the sensitizing range.Another kind is to use the filler shutoff between cable and cable and cable and bulkhead, and then coated with woven wire.Effect of the method and shortcoming are the same substantially with preceding a kind of method.Also having a kind of is to adopt the metal envelope piece make definite shape to be filled between cable and cable and cable and the bulkhead, and the method effect is better, wants custom-made but metal seals piece, and takies that volume is big, manufacturing cost is high, and weight is also big.
Summary of the invention
The purpose of this invention is to provide a kind of simple and easy, practicality and obvious results construction method, be used to shield, block the Electromagnetic Interference of space coupling.
The special penetrating technology of a kind of electromagnetic shielding cabin cable is characterized in that with the space between wire ball filled cable and cable and cable and the bulkhead, and in the both sides of wire ball difference filled conductive clay and fluid sealant successively.
Described wire ball adopts the stainless steel soft pompon usually, because this material can corrosion, goes for multiple metal hull; Described conduction clay plays ground connection and the electromagnetic wave effect that partly decays.
Further, the above-mentioned special penetrating technology of electromagnetic shielding cabin cable can be packed cable, conduction clay, fluid sealant and wire ball in the cable tube, and the cable tube passes bulkhead and cable drum outer wall and bulkhead and is tightly connected.
Above-mentioned conduction clay and fluid sealant use conventional commercially available prod to get final product.
It is long that above-mentioned cable tube is generally 80mm～100mm, in order to make the screen reliable ground of cable, the sheath of mid portion that passes the cable of cable tube can be removed, and the length of removing is 35～45mm.
This method both can make wire ball closely contact with cable shield and bulkhead, filled the space between cable shield and the bulkhead again, can not produce the space of direct puncture, shield effectiveness is good, simple, the reliable in quality, with low cost of effectively counterchecking electromagnetic wave radiated interference, and construction.
This method needing not only to go for the ship's space of electromagnetic shielding, and goes for the place that other needs electromagnetic shielding, as places such as telecommunications control room, computer rooms.
Description of drawings
The structural representation of Fig. 1 for filling with method provided by the invention
Embodiment
At first selecting tube length for use is the cable tube 8 of 80mm, is welded on the bulkhead 6 that cable 9 need pass through, and disposes rubbish and greasy dirts in the cable tube 8.In order to make the screen reliable ground of cable, peel off one section long sheath of 40mm as cable 9 surfaces that cable has oversheath then to need to pass cable tube 8, the position that this section should be peelled off sheath is positioned at 20mm place, cable tube 8 one end nozzle depths, reduce to minimum in order to make earth resistance, soldering earth connection 1 in every cable 9 external shields of peelling off sheath, and concentrate and be connected on the earth stud 3 of cable tube 8 collar extensions.Care should be used to when noting the stripping sheath can't damage its shielding, and during many cable penetrations, the cable exposure section should be neat; Do not draw when noting cable laying tension, suitably be placed with certain slackness.In the middle of cable tube 8, evenly insert stainless steel soft pompon 5, conducting resinl 4 is closely inserted on stainless steel soft pompon 5 both sides respectively in the cable tube simultaneously, must fill up and compacting,, fill the fluid sealant 2 of 20mm at cable tube 8 two ends to guarantee good electrical conductance and shielding, during installation, available putty knife is pressed into fluid sealant 2, thereby guarantees that fluid sealant is evenly filled in the cable tube, and available scraper compresses the fluid sealant between cable floating, thereby reach fabulous airtight, watertightness.
After installing, wait about 6～7 days, after glue to be sealed fully solidified, banded cable 9 again.
