Description

Stacked electric connector combination

The utility model relates to a kind of stacked electric connector combination, refer in particular to and a kind ofly lead by electricity that accessory is auxiliary to cover formed gap between the shielding casing that is placed in respectively on the craft port, and make shielding casing mutual conduction ground connection to improve the stacked electric connector combination of its screening effect.

Because the electromagnetic interference that the external world and electronic installation internal electronic element are produced is at all times, though especially under the high-frequency transmission environment trickle electromagnetic interference also influence greatly, this phenomenon will seriously influence the quality that telecommunication is transmitted.Thereby in existing electric connector, all be provided with shielding casing usually in order to the protection electromagnetic interference in the electric connector outside.Wherein relevant with this case design sees also No. the 84207854th, 85214651, TaiWan, China patent application etc.These existing stacked electric connectors combinations are most of reaches and covers electromagnetic interference function by being placed in shielding casing on each layer connector body interface respectively.Yet, each layer shielding casing when design only correspondence cover insulating body craft port near zone, therefore usually between shielding casing regular meeting have tangible gap to produce.This will cause extraneous electromagnetic interference to enter and cause telecommunication to disturb in the gap thus, make the effect of high-frequency transmission stable inadequately.In addition, also there is the shielding casing that to adhere to the different layers electric connector separately to be designed to holistic design in the existing design, just this shielding casing that fuses has the magnetic noise of can powering equally and enters gap in this electric connector combination between two craft port, and it also can't guarantee stablizing of signal transmission.And the shielding casing because of each layer electric connector connects together on making, thereby make its layer connect size and be difficult to change, when this stacked electric connector combination makes its overall dimensions or the folded mode of group slightly change be arranged in response to actual demand, promptly must make the shielding casing of different size to adapt to these different stacked modes, so will cause the mould versatility to reduce, the manufacturing cost of these electric connector combinations is greatly improved.

One of the utility model purpose is to provide a kind of stacked electric connector combination, it can be led the accessory cooperation by the electricity of auxiliary usefulness and cover on the gap between the shielding casing that is placed in respectively on the craft port, and make each shielding casing mutual conduction simultaneously, greatly to improve its screening effect.

Another purpose of the present utility model is, this stacked electric connector combination connects each shielding casing of conducting and auxiliary effect of covering is provided by part, therefore on making easily in response to different overlapped way and highly adjusted, thereby can effectively reduce cost and reduce the manufacturing stock of part.

Another purpose of the present utility model is to provide a kind of stacked electric connector combination of grounding path preferably that has.

The purpose of this utility model is to realize like this, this stacked electric connector combination mainly includes connector body, shielding casing and electricity and leads members such as accessory, wherein connector body one side surface is made as interface, on this interface, convex with simultaneously two at least and be arranged side by side and the protuberance of tool craft port, and on each craft port interior sidewall surface, be installed with several conducting terminals.In addition, this interface lengthwise to both end sides respectively be provided with the coupling hole of arranging with the craft port being aligned.Shielding casing then is coated on the periphery of craft port, and it is provided with through hole with respect to coupling hole place set on the connector body.Electricity is led accessory and then is arranged between connector body interface and the shielding casing, and be in contact with each shielding casing, so that mutual conduction between shielding casing, also can cover formed gap between these shielding casings simultaneously, with the bulk shielding effect of this stacked electric connector combination of further raising.

Compared with prior art, advantage of the present utility model is:

1. can greatly improve anti-electromagnetic interference capability of the present utility model.

2. can increase ground connection approach of the present utility model, make shield effectiveness better.
