## Abstract

An adapter having a housing, a ground clip and an adapter subassembly all located in the housing. The adapter subassembly includes a proximal portion that can be coupled to a coaxial connector and a distal portion that can be coupled to a printed circuit board. A central conductor in the form of an elongated shaft that runs through the subassembly and has a ball contact end for contacting a conductor located on a printed circuit board and the elongated shaft is tapered in a region near the ball contact.

## Claims

### Claim 1

A solderless printed circuit board edge connector comprising:
a housing including a first end and a second end, wherein at least a portion of an inner surface of the housing is non-conductive, wherein the non-conductive portion includes a cylindrical recess;
a conductive cylindrical connector, the conductive cylindrical connector being positioned partially within the cylindrical recess of the housing and partially outside of the housing;
a conductive center connector positioned within the conductive cylindrical connector;
a first contact electrically connected to the conductive center connector positioned between the first and second ends of the housing;
a second contact electrically connected to the conductive cylindrical connector positioned between the first and second ends of the housing;
wherein the distance between the first and second contacts increases when the printed circuit board edge connector engages a printed circuit board.

### Claim 2 (depends on 1)

The edge connector of claim 1, wherein the non-conductive inner surface of the housing is shaped to receive an end portion of the conductive cylindrical connector.

### Claim 3 (depends on 1)

The edge connector of claim 1, wherein the conductive cylindrical connector is press fit into the housing.

### Claim 4 (depends on 1)

The edge connector of claim 1, further comprising an insulator positioned within the conductive cylindrical connector, wherein the conductive center connector is positioned within the insulator.

### Claim 5 (depends on 1)

The edge connector of claim 1, wherein the housing is entirely constructed of a non-conductive material.

### Claim 6 (depends on 1)

The edge connector of claim 1, wherein the first contact deflects when the printed circuit board edge connector engages a printed circuit board.

### Claim 7 (depends on 1)

The edge connector of claim 1, wherein the second contact deflects when the printed circuit board edge connector engages a printed circuit board.

### Claim 8 (depends on 1)

The edge connector of claim 1, wherein both the first and second contacts deflect when the printed circuit board edge connector engages a printed circuit board.

### Claim 9 (depends on 1)

The edge connector of claim 1, wherein the return loss is better than −30 decibel from 0 Megahertz to 2500 Megahertz for printed circuit boards having a thickness of between 0.062 inches to 0.093 inches.

### Claim 10

A solderless printed circuit board edge connector comprising:
a housing including a first end and a second end, wherein at least a portion of an inner surface of the housing is non-conductive;
a conductive cylindrical connector, the conductive cylindrical connector being positioned partially within the housing and partially outside of the housing;
a conductive center connector positioned within the conductive cylindrical connector;
a first contact electrically connected to the conductive center connector positioned between the first and second ends of the housing;
a second contact electrically connected to the conductive cylindrical connector positioned between the first and second ends of the housing;
wherein the distance between the first and second contacts increases when the printed circuit board edge connector engages a printed circuit board;
wherein the return loss is better than −30 decibel from 0 Megahertz to 2500 Megahertz for printed circuit boards having a thickness of between 0.062 inches to 0.093 inches.
