Description

A kind ofly easily adorn readily removable type interconnecting cable electromagnetic shielding protective jacket

Technical field

The utility model relates to a kind of protective jacket that is used for interconnecting cable electromagnetic shieldings such as holding wire, power line, data wire, control line, is a kind of readily removable type interconnecting cable electromagnetic shielding protective jacket of easily adorning exactly.

Background technology

Along with the fast development of modern electronic technology, the frequency of electronic equipment and system is more and more higher on the one hand, causes interference and coupling and electromagnetic radiation to external world between the interconnecting cable line increasing; The residing electromagnetic environment of electronic equipment is also more and more abominable on the other hand, causes extraneous electromagnetic interference also increasing to the influence of equipment.A large amount of theory and engineering experiences show, it is 60% relevant with interconnecting cable that the electromagnetic compatibility problem of electronic equipment and system has, so the Electro Magnetic Compatibility of interconnecting cable has become an important factors of decision device and systematic function.By being coated on the electromagnetic coupled that shielded type cable made on the interconnecting cable heart yearn can effectively suppress interconnecting cable, improve the screening effectiveness of shielded type cable by metal or metallized flexible shielding body.

Shielded type cable mainly is divided three classes:

● a class is that screen is the Weaving type shielded type cable that φ 0.1mm～braiding of φ 0.15mm nickel plating copper wire forms by diameter;

● a class is that screen is the containing type shielded type cable that metallic foils such as the aluminium foil coating about 0.001mm forms by thickness;

● the 3rd class is that screen is the combined shielded type cables that metallic foil coats, skin forms for the braiding of nickel plating copper wire such as aluminium foil by internal layer.

In above-mentioned three kinds of cables, combined cable adopts maximum a kind of forms owing to combine the advantage of Weaving type and containing type shielded type cable and become the high-performance shielded type cable.But two kinds of situations have limited the application of shielded type cable in the engineering: the one, and the restriction of weight, because the woven shield very heavy (the woven shield weight that is generally about diameter phi 40mm～φ 55mm just reaches 0.333kg/m) of combined shielded type cable, thereby limited this type shielding cable requires harsh occasion to weight in aviation or space flight etc. application; The 2nd, the restriction of fault diagnosis, when carrying out failure diagnosis at the equipment work scene or to equipment, because the diameter of connector is all greater than the diameter of interconnecting cable, and this moment, cable core often installed with the connector soldering group, therefore in the time of carrying out shielding processing or improvement as if need to cable shield, have only interconnecting cable heart yearn and connector unsolder, screen could be inserted on interconnection heart yearn and the interconnecting cable.And in actual job site, generally do not allow interconnecting cable heart yearn and connector unsolder for the equipment that has assembled, especially for the important electronic equipment of the many holding wires of interconnection, so just limited the application of shielded type cable.

Summary of the invention

The purpose of this utility model be to provide a kind of have the screening effectiveness height, in light weight, the bending resistance folding endurance is good, be easy to install with use, do not destroying that interconnecting cable is connected and equipment erecting bed a kind of easily adorns readily removable type interconnecting cable electromagnetic shielding protective jacket.

For achieving the above object, the technical solution of the utility model is: a kind ofly easily adorn readily removable type interconnecting cable electromagnetic shielding protective jacket, it is characterized in that: comprise conductive fabric, conductive zippers, the two ends of conductive fabric are connected with the stiff end limit of conductive zippers by conductor wire.

Described conductive fabric is the gentle shape shield that nickel plating or plating copper and nickel metalized fibers adopt the longitude and latitude mode to be formed by weaving.

Described conductive zippers is the metal zip fastener piece of copper or copper nickel plating and conductive fabric to be suppressed by the mode of crimping constitute.

Described conductor wire is nickel plating or plating copper and nickel fiber.

The utility model has the advantages that: because electromagnetic shielding is to be made of conductive fabric 1 and conductive zippers 2, the two ends of conductive fabric 1 connect by the stiff end of conductor wire 3 with conductive zippers 2.The whole flexible tubular shield that forms makes screening effectiveness raising, weight saving, does not destroy interconnecting cable simultaneously and connects and the equipment erecting bed, can reach 40～80dB in 200K～10GHz frequency range.Make the overall screening effectiveness of protective jacket suitable with combined shielded type cable.
