Description

Can get rid of electromagnetic interference winding displacement and connector thereof

Technical field

The utility model relates to a kind of electromagnetic interference winding displacement and connector thereof got rid of, detailed is to form ground structure between a kind of winding displacement and external shell, in order to strengthen winding displacement antagonism electromagnetic interference anti noise such as (EMI, ELECTROMAGNETIC INTERFERENCE).

Background technology

Electric room all need be dependent on the media that corresponding connector transmits as signal, and general connector is to be provided with joint for two ends, or a termination head end one end is aspects such as control circuit board for reaching purposes such as automatic control or transmission interaction.

Connector is generally to be wire and to have certain-length, be positioned at the electronic equipment that does not exist together in order to be connected to, and the design focal point of connector, no more than accurately undistorted signal is transmitted back and forth, for making signal stable, so connector is also quite important for the eliminating such as noises such as electrostatic interference, electromagnetic interference;

Ground connection being designed to eliminated effective ways a kind of of noise, and the application of ground connection design, the previous TaiWan, China patent application case of applying for of for example this case utility model people number No. 96211519 " electric connector structure ", the pad bottom that its clinching is used is to be extended with for being welded in the location division that circuit board is used, make this pad be arranged at insulating body and when suppressing bonnet, also, can make this insulator structure stability and signal stability promote all to some extent by compressing tablet with the effect of insulating body electrostatic grounding;

Yet, in the above-mentioned case, its grounding function only terminates in the electrostatic grounding of insulating body, but still can not provide the ground connection effect to winding displacement effectively, but winding displacement is the maincenter assembly of signal transmission, come line and be easy to generate noises such as electromagnetic interference, if a suitable ground connection design is not arranged, then the stability of signal transmission promotes still more limited.

Summary of the invention

The utility model provides a kind of electromagnetic interference winding displacement and connector thereof got rid of, and commonly uses the disappearance that connector can't effectively overcome the noises such as electromagnetic interference of winding displacement in the hope of improving.

For reaching aforementioned purpose, the utility model is to comprise a winding displacement, an insulating body and a housing, wherein:

This winding displacement is to have to comprise a terminal layer and be coated on the outer insulating barrier of terminal layer, this terminal layer is to have spaced plural core, this terminal layer is to have the part core to be exposed to outside the insulating barrier, exposing core is to form a first terminal that can supply transmission signal in winding displacement one end, but forms second terminal of supply equipment overlap joint at least one end face of winding displacement;

This winding displacement can be for a conductive layer of ground connection to being less than that insulating barrier one side is provided with, the insulating barrier that this winding displacement is nearly the second terminal place hollows out and changes and establish the conduction material and replace, this conduction material is to can be conducting resinl, this conduction material is to contact with core and conductive layer, makes terminal layer with conduction material and conductive layer mutual conduction;

This insulating body is as the usefulness that connects, this insulating body is to be provided with holder, this holder is to establish for the winding displacement group, and make the insulating body two ends be able to the first terminal to do and connect, in addition, corresponding the first terminal one side of this insulating body is provided with convex jointing part, has access slot in this convex jointing part, this access slot is that a trip is set, and makes insulating body connect Shi Keyu with the first terminal with this trip and connects object and firmly connect;

This housing be for metal made, housing is to comprise a upper shell and a lower house, at least one is provided with shell fragment this upper and lower casing, this shell fragment also is that metal is made, this shell fragment is and the conductive layer butt, and this upper and lower casing is to be mounted on insulating body upper and lower surface and fixing winding displacement, and is provided with a pressing plate between this winding displacement and housing, this pressing plate is made for plastics, and this pressing plate can increase the stationarity of housing to winding displacement;

The utlity model has following beneficial effect, but this winding displacement removes the first terminal that forms transmission signal, extra again formation can with second terminal of equipment overlap joint, add that terminal layer is by conduction material and conductive layer mutual conduction, so first, second terminal just can see through conductive layer and produce the ground connection effect, suffers electromagnetic interference in order to prevent winding displacement and equipment;

Be with, this connector is when unidirectional or two-way assembling, because conductive layer and the made shell fragment butt of housing metal, this winding displacement just can see through conductive layer and produce the ground connection effect through shell fragment and housing, in addition, because this terminal layer is with conduction material and conductive layer mutual conduction, and this conductive layer again with the shell fragment butt, so when the utility model overlapped with the second terminal supply equipment, this equipment just can see through second terminal, conductive layer produces the ground connection effect through shell fragment and housing, is subjected to electromagnetic interference in order to prevent equipment;

Hence one can see that, and the utility model is not only simple in structure, and ground connection is respond well, really is a kind of utility model that quite has practicality and progressive, and worth industrial circle is widelyd popularize, and makes society know.
