Abstract
The invention is directed to plug-type connectors for backplane wirings composed of blade connector and spring clip, whereby the individual contact springs are surrounded by electrically conductive shieldings that are connected to contactings applied in the intermediate grid both at the backplane side as well as at the assembly side, said contactings being charged with an appropriate potential. The invention discloses various possibilities for contacting between the shielding in the spring clip and the printed circuit boards carrying the shield potential.
Claims2
A plug-type connector comprising:
- a backplane having a plurality of blades;
- a housing open at one side adapted for plugging onto blades of a wiring backplane;
- a plurality of contact springs mounted within said housing, each contact spring being adapted to contactably receive one of said blades of the wiring backplane;
- a plurality of electrically conductive tubular shields disposed within said housing such that each of said tubular shields generally surrounds one of said contact springs;
- and
- a plurality of contact pins, the contact pins being secured to the housing and protruding therefrom, each of said contact pins having at least one wire connected thereto within the housing, each wire contacting one of the tubular shields, the contact pins and wires being arranged between the tubular shields such that adjacent tubular shields are interconnected by one of said contact pins and respective wires;
- a plurality of tubular bushings disposed in the backplane in a press-fit manner, each bushing having inner inwardly directed springs which, in a plugged condition, receive a respective one of the contact pins, such that a shielding potential applied to the tubular bushings is delivered to the tubular shields through the respective inwardly directed springs, contact pins, and wires.
