Abstract
A low profile interposer with multiple electrical contacts held in a housing via a process, such as heat staking, that deforms portions of the housing into protuberances that lock the electrical contacts within openings of the housing. The contacts may be arranged in multiple parallel columns and may have an elongated dimension that is aligned at an acute angle with respect to the column direction. Distal tips of the contact portions of the electrical contacts may be bent to extend into an opening in the housing, even when the electrical contact is in an uncompressed state.
Claims22
An interposer, comprising:
- an insulative member comprising a first surface, a second surface parallel to the first surface, and a plurality of openings through the insulative member, the insulative member further comprising a shelf and a protuberance within each the plurality of openings;
- and
- a plurality of electrical contacts disposed within respective openings of the plurality of openings, each electrical contact of the plurality of electrical contacts comprising a base, a first contact portion extending from the base toward the first surface and a second contact portion extending from the base toward the second surface,
- wherein, for each electrical contact of the plurality of electrical contacts, the base is captured between a shelf and a protuberance within a respective opening of the plurality of openings.
An interposer, comprising:
- an insulative member comprising a first surface, a second surface parallel to the first surface, and a plurality of openings through the insulative member;
- and
- a plurality of electrical contacts disposed within respective openings of the plurality of openings, each electrical contact of the plurality of electrical contacts comprising a base, a first contact portion extending from the base toward the first surface and a second contact portion extending from the base toward the second surface,
- wherein, for each electrical contact of the plurality of electrical contacts:
- the base of the electrical contact is between a first portion of the insulative member and a second portion of the insulative member;
- the first portion of the insulative member is between the electrical contact and the first surface;
- the second portion of the insulative member is between the electrical contact and the second surface;
- and
- the insulative member comprises a void between the first portion and the first surface adjacent a respective opening of the plurality of openings in which the electrical contact is disposed.
An interposer, comprising:
- an insulative housing comprising:
- a first surface and a second surface parallel to the first surface;
- a plurality of openings arranged in an array and extending between the first surface and the second surface, each of the plurality of openings being bounded by a surface and comprising a groove in the surface;
- and
- a plurality of electrical contacts, each disposed within a respective opening of the plurality of openings and comprising a U-shaped base, a first beam extending from the U-shaped base, a second beam extending from the U-shaped base and an extension extending from the electrical contact, wherein, for each of the plurality of electrical contacts:
- the extension of the electrical contact extends into the groove of the respective opening;
- and
- the electrical contact is heat staked within the respective opening.
