Abstract

An edge card connector assembly has a harness-side portion connectable to a cable and a card-side portion adapted to receive a planar structure edgewise therein in a plane of entry. The edge card connector has a plurality of resilient electrical contacting members extending through the wall and is adapted for electrical connection with the cable in the harness-side portion and with the planar structure in the card-side portion. Upper and lower contacting members are disposed above and below the plane, respectively, such that the received planar structure impinges on the contacting members to urge the upper and lower contacting members away from the plane, and the upper and lower contacting members exert opposing holding pressure on the upper and lower surfaces of the planar structure at respective contact points.

First claim

The invention claimed is:

1. An edge card connector assembly, comprising:
a housing having a card-side portion, a harness-side portion connectable to a cable and a wall therebetween, the card-side portion including a walled chamber having slots to define a plane of entry for receiving a planar structure therein and adapted to receive a planar structure edgewise therein in a plane of entry, the planar structure having upper and lower surfaces; and
a plurality of resilient electrical contacting members extending through the wall and being adapted for electrical connection with the cable in the harness-side portion and with the planar structure in the card-side portion, the upper and lower contacting members being arranged as an upper set of multiple parallel rows above the plane of entry and a lower set of multiple parallel rows below the plane of entry, respectively, such that the received planar structure impinges on the contacting members to urge the upper and lower contacting members away from the plane, and the upper and lower contacting members exert opposing holding pressure on the upper and lower surfaces of the planar structure at respective contact points, the upper and lower contacting members comprising rearward extensions configured as at least one of sockets or pins that are designed to mate with pins or sockets respectively of a mating receptacle on the cable on the harness side.

2. The assembly according to claim 1 , wherein the slots terminate at the wall.

3. The assembly according to claim 1 , wherein the planar structure is a printed circuit board having electrical contacts that mate with the contacting members at the contact points.

4. The assembly according to claim 1 , wherein the housing is provided with snap-on clips that engage respective indentations of the planar structure.

5. The assembly according to claim 1 , wherein the contacting members comprise a finger portion and an elbow, the finger portion extending generally from the wall to the elbow, the elbow of at least a portion of the contacting members making galvanic contact with the planar structure at the one of the respective contact points.

6. The assembly according to claim 5 , wherein the finger portion is resilient.

7. The assembly according to claim 1 , wherein the upper set of rows and the lower set of rows total five rows.

8. The assembly according to claim 7 , wherein there are three rows in the upper set of rows and two rows in the lower set of rows.

9. The assembly according to claim 8 , wherein there are 34 contacting members.
