Background technology
Electric connector is the parts extensively used in electric signal transmission, along with constantly widening of its application, electric connector only can complete common electric signal transmission and can not satisfy the demands far away, and various electric equipment all proposes more harsh requirement to the index such as function, size, waterproof and dustproof, signal transmission quality of electric connector.Wherein signal transmission quality becomes the important indicator weighing electric connector quality in some field especially.
In traditional electric connector, mostly be to consider from metal shell and tail accessory to the shielding construction design of electric connector, such as, circular shield electric connector, it is when tail portion of connector installs cable, by the copper shield cover of inside, the metal shell of the gauze screen on cable and connector is compressed conducting, thus reach the object of shielding external interference.
The shielding of above-mentioned electric connector is owing to being only lean on the metal shell of electric connector to realize, and therefore it only can realize the overall shielding relative to the external world of electric connector, namely only can resist the interference of connector outside.But for some electric connectors, the mutual interference between its internal contacts even will exceed the interference of connector outside, if shielding construction only can resist the interference of electric connector outside, it obviously cannot meet instructions for use.Therefore, the shielding construction of current electric connector also exists the problem that shielding is comprehensive, shield effectiveness is poor.
Summary of the invention
The object of the present invention is to provide a kind of full-shield electric connector, to solve the problem that the shielding of existing shield electric-connector is comprehensive, shield effectiveness is poor.
In order to solve the problem, full-shield electric connector of the present invention is by the following technical solutions: full-shield electric connector, comprise metal shell, dielectric member and contact parts, described dielectric member comprises the inner insulator and outer insulator that are fixedly assembled together, be provided with inner shield cover between inner insulator and outer insulator, contact parts comprise the inner layer contacts part be assemblied on inner insulator and the outer layer part be assemblied on outer insulator.
One in described inner insulator and outer insulator is equipped with positioning key, another is equipped with the featherway coordinated with positioning key, coordinated by described positioning key key between outer insulator with inner insulator, the respective end of inner shield cover is provided with the keyway coordinated with positioning key.
Described dielectric member also comprises fixed insulation body, and fixed insulation body to be fixed in metal shell and to compress inner insulator from front to back, and inside and outside layer insulator is fixed together by fixed insulation body.
Described fixed insulation body is fixed in metal shell by jump ring.
One in described outer insulator and metal shell is provided with directing pin, and another is provided with guiding groove, by directing pin and guiding groove location fit between outer insulator and metal shell.
Metal shell inwall is provided with the otic placode extended internally in the rear end of dielectric member, dielectric member is fixed in metal shell by the screw that described otic placode is arranged.
Dielectric member due to full-shield electric connector of the present invention comprises the inner insulator and outer insulator that are fixedly assembled together, and be provided with inner shield cover between inner insulator and outer insulator, contact parts comprise the inner layer contacts part be assemblied on inner insulator and the outer layer part be assemblied on outer insulator, therefore, when in use, inner shield cover can play the effect isolated mutually between inner layer contacts part and outer layer part, thus by the interference of metal shell shielded connector outside, interfering with each other between the contact of being isolated both sides inside and outside it by inner shield cover, and then realize the comprehensive shielding of electric connector, solve the shielding of existing shield electric-connector not comprehensive, the problem of shield effectiveness difference.
