Abstract
Abstract A surface mountable electronic component socket for mounting on the surface of a printed circuit board includes a socket made of insulative material and a plurality of surface mountable terminals which are disposed within the socket body. Each terminal includes a lead portion for surface mounting on an associated contact area of a circuit board, and a hollow body section adapted to receive the lead of an integrated circuit or other electronic component. Each terminal is axially movable or floatable within its respective opening in the socket. This axial movement of the terminals accommodates misalignment which may occur between the surface mounted leads and the printed circuit board thereby providing reliable engagement of the socket with the circuit board.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A surface mount socket for removably retaining an electronic component having a plurality of leads, the socket comprising: a housing of insulative material having a plurality of through holes, each having a diameter sized to receive and retain a respective terminal; and a plurality of terminals each retained in a respective through hole of the housing, each of the terminals including: a body section having a head portion on one end and a lead portion on the opposite end; the body section having an outside diameter slightly smaller than the diameter of the through hole of the housing and an axial length greater than the length of the through hole to permit axial movement of the terminal in the through hole; the head portion having a diameter larger than the diameter of the through hole; and the head portion having a diameter larger than the diameter of the through hole; and at the juncture between the body section and the lead portion and having a diameter greater than the diameter of the through hole.
Claim 2
Dependent Claim
174 words
A surface mount socket for removably retaining an electronic component having a plurality of leads, the socket comprising: a housing of insulative material having a plurality of through holes, each having a diameter sized to receive and retain a respective terminal; and a plurality of terminals each retained in a respective through hole of the housing, each of the terminals including: a body section having a head portion on one end and a lead portion on the opposite end; the body section having an outside diameter slightly smaller than the diameter of the through hole of the housing and an axial length greater than the length of the through hole to permit axial movement of the terminal in the through hole; the head portion having a diameter larger than the diameter of the through hole; and the head portion having a diameter larger than the diameter of the through hole; and at the juncture between the body section and the lead portion and having a diameter greater than the diameter of the through hole.
Claim 3
Dependent Claim
90 words
The surface mount socket of claim 1 wherein: each of said plurality of terminals is retained in said housing by said head portion and said retaining means such that each terminal is axially movable over a length defined by a space separating the head portion and the retaining means; the body section and head portion include a cavity for receipt of a lead of an electronic component mounted on the socket; and the lead portion includes an outer end surface, mountable on a contact area of a printed circuit board.
Claim 4
Dependent Claim
145 words
A terminal for removably retaining an electronic component lead and for mounting within a through hole in a socket wherein said terminal comprises: a body section having a head portion on one end and a lead portion on the opposite end; the body section having an outside diameter slightly smaller than the diameter of the through hole of the socket and an axial length greater than the length of the through hole to permit axial movement of the terminal in the through hole; the head portion having a diameter larger than the diameter of the through hole into which the terminal is to be mounted; and retaining means integral with the terminal and disposed at the juncture between the body section and the lead portion and having a diameter greater than the diameter of the through hole into which the terminal is to be mounted.
Claim 5
Dependent Claim
145 words
A terminal for removably retaining an electronic component lead and for mounting within a through hole in a socket wherein said terminal comprises: a body section having a head portion on one end and a lead portion on the opposite end; the body section having an outside diameter slightly smaller than the diameter of the through hole of the socket and an axial length greater than the length of the through hole to permit axial movement of the terminal in the through hole; the head portion having a diameter larger than the diameter of the through hole into which the terminal is to be mounted; and retaining means integral with the terminal and disposed at the juncture between the body section and the lead portion and having a diameter greater than the diameter of the through hole into which the terminal is to be mounted.
Claim 6
Dependent Claim
30 words
The terminal of claim 3, wherein the retaining means includes a tapered ring having its greater diameter confronting a through hole of a socket in which the terminal is mounted.
Claim 7
Dependent Claim
27 words
The terminal of claim 4, wherein the lead portion of the body section includes a contact for surface mounting to a contact area of a circuit board.
Claim 8
Dependent Claim
83 words
The terminal of claim 3 wherein: the terminal is retained in the socket by the head portion and the retaining means and is axially movable over a length defined by a space separating the head portion and the retaining means; the body section and the head portion having an internal cavity for receipt of a lead of an electronic component mounted on the socket; and the lead portion having an outer end surface, mountable on a contact area of a printed circuit board.
Claim 9
Dependent Claim
44 words
The terminal of claim 6, wherein said retaining means comprises a top edge and an outer wall wherein: the top edge extends perpendicular to the outside diameter of the body section; and the outer wall tapers from said top edge to the lead portion.
Claim 10
Dependent Claim
23 words
The terminal of claim 4, wherein the internal cavity of the body section includes means for engaging a lead of an electronic component.
