Abstract
Abstract A dual inline integrated circuit socket having nonpluggable electrical pin positions relative to receiving the leads of an integrated circuit package. The socket provides this function by means of a cap having "blind" positions or a "short" cap to allow access to the nonpluggable electrical contacts.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
236 words
An improved socket for receiving the leads of a dual inline integrated circuit package or the like pluggable unit comprising: an insulative body having a plurality of longitudinally spaced apart socket apertures extending through the body and arranged adjacent opposite longitudinal edges of the body in parallel aligned rows, the spacing between each of the sockets in said rows being substantially the same, a plurality of electrical conducting contacts having a female socket portion constructed and defined at one end and a male terminal extending therefrom, the contacts being mounted and held in each of the socket apertures with the male terminals extending outwardly from one side of the insulative body, and an insulative cap member having a preselected lengh with a plurality of longitudinally spaced apart entry apertures constructed and defined to extend through the cap member and arranged in aligned parallel rows adjacent opposite edges of the cap member, the cap member being secured to the insulative body with each of the entry apertures mounted in vertical alignment with the corresponding female socket portions, the number of entry apertures defined in the cap member being less than the number of socket apertures containing female socket portions in the insulative body but permitting the leads of an integrated circuit package or the like pluggable unit to be mounted into the entry apertures of the cap member in an electrical conducting relationship with the electrical contacts.
Claim 2
Dependent Claim
236 words
An improved socket for receiving the leads of a dual inline integrated circuit package or the like pluggable unit comprising: an insulative body having a plurality of longitudinally spaced apart socket apertures extending through the body and arranged adjacent opposite longitudinal edges of the body in parallel aligned rows, the spacing between each of the sockets in said rows being substantially the same, a plurality of electrical conducting contacts having a female socket portion constructed and defined at one end and a male terminal extending therefrom, the contacts being mounted and held in each of the socket apertures with the male terminals extending outwardly from one side of the insulative body, and an insulative cap member having a preselected lengh with a plurality of longitudinally spaced apart entry apertures constructed and defined to extend through the cap member and arranged in aligned parallel rows adjacent opposite edges of the cap member, the cap member being secured to the insulative body with each of the entry apertures mounted in vertical alignment with the corresponding female socket portions, the number of entry apertures defined in the cap member being less than the number of socket apertures containing female socket portions in the insulative body but permitting the leads of an integrated circuit package or the like pluggable unit to be mounted into the entry apertures of the cap member in an electrical conducting relationship with the electrical contacts.
Claim 3
Dependent Claim
37 words

Claim 4
Dependent Claim
33 words
An improved integrated circuit socket as defined in claim 2 wherein the cap member has N-2 entry apertures with one blind spot arranged in each row of entry apertures over a socket aperture.
Claim 5
Dependent Claim
25 words
An improved integrated circuit socket as defined in claim 3 wherein the blind spots are arranged at the ends of each row of entry apertures.
Claim 6
Dependent Claim
26 words
An improved integrated circuit socket as defined in claim 4 wherein the blind spots are arranged at the same end of each row of entry apertures
Claim 7
Dependent Claim
44 words
An improved integrated circuit socket as defined in claim 5 wherein the insulative body and cap member are both defined to have essentially the same length and width with a coextensive relief area defined in the body and cap member at said same end.
Claim 8
Dependent Claim
128 words
An improved socket as defined in claim 1 wherein the cap member has a preselected length shorter than the length of the insulative body but having said number of entry apertures and the electrical contacts are mounted in the body at the location corresponding to a location outside the perimeter of the cap member and the short length of the cap member exposes and allows access to at least a pair of the electrical conducting contacts at the female socket portions thereof at an upper surface of the insulated body, and the insulative body is constructed and defined with a relief area intermediate the end of the cap member and the insulative body, and an electrical component secured to said pair of electrical contacts at said socket portions.
Claim 9
Dependent Claim
16 words
An improved socket as defined in claim 7 wherein the electrical component is an electrical capacitor.
Claim 10
Dependent Claim
77 words
An improved socket as defined in claim 1 whereinthe cap member has a preselected length shorter than the length of the insulative body and electrical contacts are mounted in each of the socket apertures, the length of the cap member is selected to expose and allow access to at least a pair of the electrical contacts at the female socket portions at an upper surface of the insulative body and outside the perimeter of the cap member.
Claim 11
Dependent Claim
59 words
An improved socket as defined in claim 9 wherein the cap member allows access to the pir of electrical contacts arranged adjacent an end of the insulative body and on opposite sides thereof and the insulative body is constructed and defined with a relief area intermediate said pair of electrical contacts and outside the perimeter of the cap member.
Claim 12
Dependent Claim
215 words
An improved socket including an insulative body having a preselected length for defining a pair of rows of longitudinally extending equally spaced apart sockets arranged therein for mounting electrical contact elements in the sockets, the number of sockets being N, and an insulative cap removably secured to the body, the cap having a length to at least overlie the socket openings in the insulative body and having entry apertures therein for permitting electrical access through the cap to electrical contact elements mounted in each of the sockets, the improvement comprising an insulative cap member having a length to at least overlie all of the socket openings in the insulative body but having N minus a number equal to or greater than 1 entry apertures for the sockets that it overlies, the entry apertures are arranged in longitudinally extending parallel rows adjacent opposite edges of the cap member for permitting electrical contact with an electrical contact arranged in the socket through an entry aperture and with one blind spot arranged at the same end of each row of entry apertures over an entry aperture for preventing electrical contact with an electrical contact arranged in the socket at the blind spot, the cap member being adapted to be removably secured to one side of the insulative body.
Claim 13
Dependent Claim
215 words
An improved socket including an insulative body having a preselected length for defining a pair of rows of longitudinally extending equally spaced apart sockets arranged therein for mounting electrical contact elements in the sockets, the number of sockets being N, and an insulative cap removably secured to the body, the cap having a length to at least overlie the socket openings in the insulative body and having entry apertures therein for permitting electrical access through the cap to electrical contact elements mounted in each of the sockets, the improvement comprising an insulative cap member having a length to at least overlie all of the socket openings in the insulative body but having N minus a number equal to or greater than 1 entry apertures for the sockets that it overlies, the entry apertures are arranged in longitudinally extending parallel rows adjacent opposite edges of the cap member for permitting electrical contact with an electrical contact arranged in the socket through an entry aperture and with one blind spot arranged at the same end of each row of entry apertures over an entry aperture for preventing electrical contact with an electrical contact arranged in the socket at the blind spot, the cap member being adapted to be removably secured to one side of the insulative body.
