Abstract
A fastening system for attaching two components with a spring force is disclosed. The fastening system utilizes O-rings to provide the spring force, eliminating the need for any metal components. The O-ring may be disposed in an O-ring holder that has a plurality of spokes. When compressed, indentations are created in the O-ring by the spokes. The number of spokes and their size and shape determine the spring force of the fastening system. In another embodiment, vertically oriented O-rings are utilized. The fastening system may be used to fasten various components of an ion source.
Claims19
A fastening system for fastening a first component to a second component, comprising:
- a pin, having a head and a body;
- a latch having a flange and a center opening dimensioned so that the body of the pin passes therethrough;
- an O-ring holder having a circular recess with a bottom, an inner sidewall and an outer sidewall, wherein the O-ring holder is separate from and disposed on the second component;
- and
- a O-ring, where the O-ring is disposed in the circular recess and contacts an underside of the latch and the O-ring holder and wherein the flange extends downward and covers the O-ring and at least a portion of the outer sidewall of the O-ring holder.
A fastening system for fastening a first component to a second component, comprising:
- a pin, having a head and a body;
- a latch having a center opening dimensioned so that the body of the pin passes therethrough;
- an O-ring holder having a plurality of vertical slots;
- and
- a plurality of O-rings, where each of the plurality of O-rings is disposed in a respective vertical slot, and contacts an underside of the latch.
An extraction plate assembly for use with an ion source, comprising:
- an extraction plate having an extraction aperture;
- and a hole proximate the extraction aperture;
- a blocker, having an opening;
- and
- a fastening system, comprising:
- a pin, having a head and a body, passing through the hole and the opening;
- a latch having a flange and a center opening dimensioned so that the body of the pin passes therethrough;
- an O-ring holder;
- and
- an O-ring, wherein the O-ring is disposed in the O-ring holder and contacts an underside of the latch and wherein the flange extends downward and covers the O-ring and at least a portion of the O-ring holder.
