Abstract
A connector can be provided that allows for improved route-out including straight-back routing. Signal and ground terminal tails can be arranged in a single row to help facilitate such functionality. Consequentially, a connector with two vertically stacked card slots can be provided that allows for straight back routing of the signal traces in four layers while still providing a compact connector design.
Claims12
A connector, comprising:
- a housing have a card slot;
- a first wafer having a first and second ground terminal, the first and second ground terminals having, respectively, a first and second contact positioned on opposite sides of the card slot, the first wafer having a bar electrically connecting the first and second ground terminal, the bar including a plurality of first junctions;
- a second wafer having a first signal terminal and a second signal terminal, the second wafer supporting a plurality of tail stubs, the signal terminals each having a contact, a signal tail and a body extending therebetween, the contacts of the first and second signal terminals positioned on opposite sides of the card slot and the plurality of tail stubs each having a second junction and a ground tail;
- a third wafer having a third signal terminal and a fourth signal terminal, the third and fourth signal terminals each having a contact, a signal tail and a body extending therebetween, the contacts of the third and fourth signal terminals positioned on opposite sides of the card slot, the first terminal of the second wafer and the third terminal of the third wafer forming a first broad-side coupled differential pair and the second terminal of the second wafer and the fourth terminal of the third wafer forming a second broad-side coupled differential pair;
- and
- a plurality of conductive members electrically connecting the first junctions with the second junctions.

A connector, comprising:
- a housing having a first side and a mounting side, the first side including a card slot and the mounting side configured to be mounted on a circuit board;
- a first wafer that supports a plurality of first signal terminals, each first signal terminal including a contact, a tail and a body extending therebetween;
- a second wafer that supports a plurality of second signal terminals, each second signal terminal including a contact, a tail and a body extending therebetween, the bodies of the first and second signal terminals being in a broad-side coupled relationship, wherein at least one of the first and second wafers supports a plurality of tail stubs;
- a third wafer that supports a plurality of ground terminals, each ground terminal including a contact and a body and an end, the ground terminals not including a tail;
- and
- at least one commoning member electrically connecting the ends to the tail stubs.
3 more elements
A connector, comprising:
- a housing with a card slot on a first face, the card slot having a first side and a second side;
- and
- a plurality of wafers arranged in pattern that includes a ground wafer, a signal wafer and a signal wafer, each of the plurality of wafers supporting a first signal terminal and a second signal terminal, the first signal terminal having a contact on the first side and the second signal terminal having a contact on the second side, ground terminals each having an end, the ends being electrically connected to tail stubs supported by the signal wafers.
