Definitions
- the invention relates to a shielded electrical connector for Printed circuit boards, in particular surface-mounted connectors, flatter Design consisting of a connector in which electrical connection elements are arranged in isolation, for contacting pin contacts a complementary connector are provided, wherein at least one side of the connector is covered with a shielding plate is which connection ends for connecting to conductor tracks one Has printed circuit board, and wherein the electrical contacting of the shielding plate of the connector with the shielding plate of the complementary Connector takes place by means of contact elements.
- Shielding electrical connectors is to improve the Transmission properties in the RF range, as well as for the greatest possible reduction own and third-party interference signals required.
- EP 0 637 858 A1 is a shielded electrical one Plug connection for printed circuit boards, consisting of a connector, in the electrical connection elements are arranged insulated, which for Contacting of pin contacts of a complementary connector provided are, with at least one side of the connector with a Shielding plate are covered, which connection ends for connection with Has conductor tracks of a circuit board, known.
- WO 98/09 354 A1 describes a shielded connector for Printed circuit boards, being used for shielding between the rows of A shield plate is provided in each connector in the contact elements and wherein the contact elements are on the same level as the shield plates lie.
- the invention has for its object a shielded connector of the type mentioned in the beginning to form a shield to be provided, which reduces the overall height to a minimum.
- the advantages achieved by the invention are in particular that the overall height of the connector is significantly reduced. Furthermore is due to the constant distance between the plug contacts and the shielding has a constant impedance curve across the entire connector width reached along the signal path.
- the ring-shaped, closed spring tongues also show a better shielding effect than conventional narrow shielding tongues.
- 1 and 2 is a connector, consisting of a connector 1 and a mating connector 2 shown.
- FIG. 1 shows that applied to a printed circuit board 5 Connector 1 with its protruding electrical spring contacts 20 inside the insulating case 3 in rows and Columns are arranged.
- the contact with the mating connector 2 takes place via the knife contacts 21, which are guided in bushings 23 within the insulating housing 4 and enable the electrical signal connection to a printed circuit board 6.
- the shielding plate 7 on the upper and lower side of the connector 1 is connected to conductor tracks 16 of the printed circuit board 5 by means of contact tabs 15, shown here in a resilient manner, the shielding plate 7 being locked in the channel 25 with the insulating body 3.
- the shielding plates 8 of the mating connector 2 are connected by means of pin-shaped shielding contacts 17, which are guided through openings 18 in the insulating body 4, via conductor tracks 19 to the ground potential of the printed circuit board 6.
- Fig. 2 are the two connectors in a perspective view 1 and 2 shown in a position just before plugging together. It can be seen that the shielding plates 8 of the mating connector 2, arranged within the outer boundary of the insulating body 4 - above and below are while the knife contacts 23 for electrical signal transmission arranged in rows and columns, inserted in between are. (see also Fig. 1)
- rectangular recesses 22 are provided, in which the flat fastening hooks 24 for the shielding plate 7 of the connector 1 when plugging the two connectors together so that a seamless surface transition between the two connectors is achieved becomes.
- the shielding plate 7 during its assembly, first with its contact tongues 9 in inserted the front flat fastening hooks 24 of the connector 1 and then with locking tabs 13 in corresponding recesses 14 locked in the insulating housing 3 of the connector 1. Doing so simultaneously the shielding plate 7 with its rear end part bent by 90 ° 26 in a correspondingly shaped groove 25 in the insulating housing 3 of Inserted connector 1 and there by means of not shown locking elements locked. This is an electrical connection via the spring here trained contact tabs 15 which on the conductor tracks 16 of the Press circuit board 5, ensured.
- the two plug connectors are connected to one another, so the shielding plates 7 and 8 of the two connectors 1 and 2 contacted each other by the Contact tongues 9 and 10 side by side on one level in each mutually provided gaps so that the ring-shaped trained contact tongues 9 and 10 on the lateral contact surfaces 11 and touch 12.
- the oval rings shown in the example are used slightly compressed and result in a safe electrical contact.
