Definitions
- the present invention relates to a shielded cable connector according to the preamble of claim 1 and to a combination of such a shielded cable connector and a plug-in plug-in card for electronic data processing devices according to the preamble of claim 7.
- a shielding contact is provided separately on the contact carrier, which is connected to the shield housing during assembly of the shielded cable plug.
- the plug-in card is also provided with a separate shielding contact on its connector part, which is connected to the metal housing of the plug-in card.
- the object of the present invention is therefore to provide a shielded cable connector of the type mentioned, in which a simplified connection can be made from the shielding of the cable used to the shielding contact of the cable connector, and a combination of such a shielded cable connector and a plug-in card of the type mentioned To create a way in which also a connection between the shielding of the cable used via the in the simplest possible and essentially without additional parts to be used Connector to the shield housing of the plug-in card is accessible.
- the features specified in claim 1 are achieved in a shielded cable connector of the type mentioned and in the combination of such a shielded cable connector and a plug-in plug-in card by the features specified in claim 7.
- the measures according to the invention avoid the complicated process of connecting the shield housing and the shield contact in the case of shielded cable plugs, since the shield housing in the form of one or more shield contact tabs is merely extended.
- the transfer of the shielding contact from the shielding of the cable used to another component by the cable connector is possible by a simple crimp connection and without further electrical transitions.
- a continuous shielding from the shielding of the cable used to the plug-in card without additional parts and without further electrical transitions than that of the crimped connection and the plug connection is achieved by the measures according to the invention.
- the reduction in the number of components required for this enables cost-effective production and connection.
- a mechanical connection between the shield housing of the cable connector and the contact carrier is achieved at the same time by the features according to claim 2.
- shield housing of the shielded cable connector result from the features of one or more of claims 4 to 6.
- shielding contact tabs as many shielding contact tabs as possible are to be provided, on the one hand to make the combination of cable connector and plug-in card as shield-tight as possible and on the other hand to ensure security to increase the shield contact.
- the shielding contact tab of the cable plug as well as the relevant connector part is brought into or through the end plate of the plug connector part of the plug-in card, so that there is a contact connection between the shielding contact tab and the metal housing of the plug-in card.
- This can be done, for example, in such a way that the shielding contact tab or tabs contact the metallic housing of the plug-in card from the inside.
- this may conceal the Danger in itself that the relatively thin-walled metallic housing of the plug-in card bulges outward when the contact pressure of the shielding contact tab is too high and then protrudes over the end plate of the connector part. This could potentially result in injury.
- the features according to claim 8 are provided in a preferred embodiment of the present invention.
- the contact pressure of the shielding contact tab or tabs from the recessed outside of the metallic housing of the plug-in card is given inwards, so that there is no danger that areas of the metal housing of the plug-in card can protrude beyond the outer circumference of the connector part .
- FIG. 1A is a perspective view of a shielded cable connector according to a preferred embodiment of the present invention
- FIG. 1B shows a perspective view of a with the shielded cable connector according to FIG. 1A plug-in plug-in card for electronic data processing devices according to an embodiment of the present invention
- FIG. 2 shows a perspective exploded view of the individual components of the shielded cable connector according to FIG. 1A
- Figure 3 is a schematic, partially broken and enlarged view of a section along the line IIIA-IIIA of Figure 1A and along the line IIIB-IIIB of Figure IB and
- Figure 4 shows a section corresponding to Figure 3, but in the assembled position of the shielded cable connector and plug-in card.
- the shielded cable connector 10 shown in accordance with a preferred exemplary embodiment of the present invention is provided in particular in the design as a PCMCIA cable connector, in which it is designed with a multiplicity of poles and in a very small size.
- the shielded cable connector 10 has a contact carrier 11 which is provided with a frame plate 12.
- the front area of the contact carrier 11 is designed as connector parts 13 and 14, which protrude in one piece from the frame plate 12 and are elongated flat and are provided with asymmetrically arranged rails 16, 17 for unmistakable insertion into the IC plug-in card 50, for example.

- the cable 23 is also provided with a shield 24, shown only schematically, for example in the form of a wire mesh, and with an insulation 25 surrounding the shield 24.
- the cable connector 10 also has a shield housing 30, which is composed of two housing shells 31 and 32. The two housing shells formed from a thin sheet of metal
- the two housing shells 31 and 32 have a large-area plate 33, 34, which are each provided with narrow narrow edges 35 and 36 on the side.
- the two housing shells 31 and 32 have a width corresponding to the width of the contact carrier 11 on their front area and run trapezoidally on their rear area facing the cable 23.
- the two housing shells 31 and 32 can be locked into one another by means of their overlapping edges 35 and 36.
- the 32 has at its rear end facing the shielded cable 23 a cable crimp 37 in the form of a U-shaped channel part 38 with three or four protruding fingers 39.
- the upper housing shell 31 is provided with a web 40 opposite the cable crimp 37, between which and the shield 24 of the shielded cable 23 is arranged in the cable crimp 37.
- the connection of the shield 24 of the cable 23 to the two housing shells 31 and 32 takes place in that the cable crimp 37 or its finger 39 is shaped or crimped tightly around the shield 24 and the web 40.
- Both housing shells 31 and 32 are provided at their front end with shielding contact tabs 43 and 44 which project in one piece over their front edge 41, 42.
- two spaced shielding contact tabs 43 and 44 are provided per housing shell 31, 32.
- the shielding contact tabs 43, 44 are opposite the plate 33 and 34 of the two housing shells 31 and 32 in the region in which they penetrate the slots 45 and 46 of the frame plate 12 with one pointing towards the outside Bend.
