Technical field

The present invention relates to novel joint design scheme, described joint is used for to instrument and the power supply of their particular device, especially for integrated with rfi filter or equipment.

The invention particularly relates to the integrated package of a kind of power cable and circuit, described assembly is used for a kind of instrument with sidewall or shell, and described assembly comprises a power cable and a circuit, and described circuit is a rfi filter especially.A kind of like this assembly is disclosed in EP0805617A1.

First innovative characteristics of the present invention is; be provided with a plate for the end of the power cable of instrument; this plate and power cable itself compound molded (over moulded) together; described plate will be accommodated in the aperture of the sheet metal of instrument or shell; the inner surface of this plate can both be connected on the supporting member that is used for keeping such as radio frequency interference equipment by coupling; be connected to again on its electric wire and electric connection; electric wire and electric connection are essential for the operation of instrument; described supporting member is embedded in the case structure spare; this case structure spare sealing is also protected above-mentioned parts, guarantees that their intensity reaches the safety standard of electrical connection.

Described safety standard can be predicted, the existence of electronic filter can suppress or reduce the electromagnetic noise because of using instrument to bring, will avoid the chance of connector component (connectorblock) except constructional adjusting and open and will guarantee the installation fastness of cable, described safety standard makes the builder want the electric wire of integrated maximum, to constitute case structure spare, wherein compound molded contact is inserted into or is connected to by any way on the printed circuit and can support described filter and cable sealed (cable blocking) device with electric wire and general electric connection, so that feasible volume and time that is spent and cost minimization according to the standard equipment manufactured thereby.

Background technology

In above-mentioned known technology, above-mentioned patent EP0805617A1 has predicted a kind of realization of integrated package of connector component-filter, this integrated package comprises a centerbody with a hollow bulb, it has held described that be integrated and the assembled parts of a rfi filter (RFI filter), and a series of electric terminals are placed on the side stand that is connected on the described main body, also have a mechanical cable lock uint to be employed thereon.

Other known technology is predicted, no matter adopt what mode all to be provided with one or polylith plate with different elements fixing and supporting RFI filter and connector, each technology and the difference of all the other technology only be the layout of element different and they to be fixed to the shell or the fixture on the wall of instrument different.

All these known technologies are also predicted, and filter and its wiring system are inserted in the electrolysis tank of electric insulation resin, thereby are cured, and only electric connection derives from this.

Thereby with the current techique that the element embedded resin is cured mainly is because must make filter joint and power cable overhang insulation.In fact, this process has been brought a serious ecological problem, promptly under the situation of changing filter-connector assembly or under the situation of instrument wearing and tearing, select different elements because the resin itself that solidifies has hindered by the material type that can be recovered, cause thus can not recycling waste products.

And, oral area at described connector-filter assembly is provided with cable clip so that the sealed necessity of power cable, electric contact in making this power cable joint and being located at same assembly can not in time be set up and connect, this makes setter only after insertion and fixed cable, could on each device, realize these connections, this will bring very big inconvenience to duration of work, except inconvenient and attached cable pressed from both sides the extra time that needs, this means that the time and the cost that spend on the finished product are too many.

Another nearest technology foresight is to such possibility: near joining power cable connector only, and by the resin that is placed in the opening that its end is sealed then, so that the joint of power cable and filter and connector are insulated.However, this technology proposes to adopt a printed circuit, and this circuit is received every connecting wire on the corresponding contact of the box structural member of connector (connector box).

Or this technology, although it has cancelled the existence that needs the cable clip of layout during laying, thereby has improved prior art, the shortcoming that exists has been to use resin, resin makes structural member and printed circuit not recyclable, and this will cause producing not recycling waste products.

Constituting potential problems of the present invention is, realize especially integrated with a RFI filter of an electrical cnnector and another equipment---its can fully be realized in advance and the aperture of sheet metal by inserting the instrument that will be powered or shell in and directly installed, and the necessity of not carrying out the sealed and last wiring subsequently of cable, this does not use insulating resin just to realize.

Constituting another potential problems of the present invention is: under the situation of one of parts of changing electrical cnnector or under the situation that instrument itself damages, come built in items or printed circuit is installed owing to exempted the use insulating resin, thereby any parts in recyclable and/or described electrical cnnector of ecological ground recycling and the filter.

Constituting another potential problems of the present invention is, realizes wiring between power cable contact and integrated filter or other device, but guarantees to change the possibility of each parts, to avoid changing whole cable-filter body.

Constituting also potential problems of the present invention is, implements a kind of structural member, and this structural member supports described electrical cnnector and integrated device, i.e. RFI filter, and this is the most reliable, because firm and safety, and install easily.

Constitute of the present invention at last but be not that least important potential problems are, will reduce to minimum in the inconvenience during the application integration connector component, and subdue thereupon and use cost and the time that this connector component itself is spent.

These problems be the invention solves fully.
