Description

The The invention relates to a connector with a connected thereto Shielded cable according to the preamble of claim 1 and a method according to the preamble of claim 10.

The Creation of a conductive connection between a cable shield and a connector does not require one in the prior art to be underestimated constructive and assembly technical Effort.

The Invention has the task to solve this problem.

The Invention solves this problem by the subject matter of the claim 1. The invention further provides the method of claim 10 and the subject matter of the independent claim 9.

To the indicator of claim 1, the connector has at least a sprayed screen element made of a sprayable electrically conductive Material, in particular an electrically conductive plastic, on, which is conductively connected to the cable shield. The production of this Umbrella element is particularly simple and straightforward and it will achieved a very good shielding.

According to one Variant of the invention is the sprayed screen element as preferred formed circumferentially closed shielding sleeve, whereby a particularly good shielding is achieved. This shielding sleeve can optionally with another serving for shielding device be connected to the connector.

Exemplary are suitable sprayable conductive materials in the WO 2005/057590 A1 specified.

advantageous Embodiments are to be taken from the subclaims.

following the invention is based on embodiments below With reference to the drawings described in more detail. It shows:

1 to 5 a schematic representation of a manufacturing process of a connector with a cable connected thereto based on a state representation in each case after passing through successive manufacturing steps;

6 a sectional view of the connector 5 ; and

7 another connector with two cables in the manner of a T-connection.

1 shows a cable 1 comprising at least one or more individually by a conductor insulation and / or by a surrounding jacket 3 insulated conductors 2 having in common, or at least part of a cable shield 4 , in particular of a braided shield, are enclosed, which extends over the axial length of the cable. The cable can also have a cable shield 4 surrounding insulating cladding 5 have (see also 5 ).

The cable 1 is - here at a free end - to a connector 6 connected, which can be plugged together with a corresponding connector, not shown here.

In the production, the conductors are first 2 or their conductive wires in a stripped and possibly stripped end region with not shown contacts of a contact carrier 7 connected to the connector ( 1 ).

Preferably, the cable shield 4 in its axial end on the connector 6 from the connector 6 way back over the serving 5 handled.

An area in which the individual wires or the conductors 2 stripped to the contact wearer - 1 - Can with an insulating, electrically non-conductive plastic to form a sectional insulating jacket 8th to be overmoulded ( 2 ). Make sure that the cable shield 4 in some cases not from the insulating jacket 8th is wrapped.

It can be provided then via the contact carrier an electrically conductive configured connecting element such as a coupling nut 9 , preferably made of metal or an electrically conductive plastic ( 3 ), which serves for connection or coupling with a corresponding connection element of a corresponding connector.

Then the cable shield will be 4 in sections and if present, in particular in the folded area - with an electrically conductive material, in particular an electrically conductive plastic, encapsulated, so that a sprayed shielding sleeve 10 made of electrically conductive material. The shielding sleeve 10 on the one hand, preferably directly with the cable shield 4 , especially in the handled. Range, and on the other hand directly or optionally via a conductive metal sleeve 11 with the electrically conductive, a part of a extending in the axial direction shielding connecting element 9 - here the clutch mother 9 - connected. The connecting element is used for contacting a shielding on the corresponding connector (not shown here) or on a housing or a printed circuit board or the like.

The connecting element is here as a coupling nut 9 formed, which preferably consists of metal and is further designed here for screwing with a corresponding external thread made of metal of the corresponding connector.

The thus prefabricated arrangement ( 4 ) may conclude to form a housing or handle portion 12 be encapsulated with an insulating plastic, wherein possibly also the still exposed area of the cable shield is encapsulated ( 5 ). The mating face of the connector 6 bears the reference number 13 , A sectional view of the connector 5 shows 6 ,

7 shows a particularly preferred embodiment, in which a connector 6 ' two shielded cables 1 and 1' are connected, which are conductively connected in the region of the contact carrier, so that with the connector 6 ' a kind of T-shaped branching is realized. An appropriately sprayed shielding sleeve is used here in a particularly advantageous embodiment for realizing a conductive connection of the two cable shields of the two cables led to the connector 1 and 1' (not visible here).

It is also conceivable, the coupling nut 9 made of a conductive plastic.

at the sprayed conductive material, in particular plastic, can it is for example an electrically conductive polymer or a plastic / metal hybrid material.
