Abstract
Abstract A carrier for dual-in-line integrated circuit package having a rigid flat body is provided with retention means including an opposite pair of cantilever fingers integrally formed in opposite walls of the carrier and rearwardly extending therefrom in elongated form and at an acute angle with body-engaging surfaces provided with a plurality of rearwardly spaced-apart detents to accommodate bodies of differing thicknesses. The cantilever fingers are adapted to be deflected toward the walls by insertion of the body with at least one of the detents engaging a side of the body in a finger-force releasing relationship. The carrier also is provided with guide shoulders and rearwardly positioned support shoulders for predetermined positioning of the packages.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
201 words
A carrier adapted to receive an inserted dual-in-line integrated circuit package having leads and a generally flat rigid body with rearwardly extending side surfaces, said carrier comprising a one-piece insulating housing including a front face, a cavity having a generally rectangular cross-section extending rearwardly from said face and sized to receive said package, a plurality of rearwardly extending walls forming said cavity with frontwardly disposed surfaces for receiving said leads in spaced relationship and rearwardly disposed supporting surfaces for rearwardly positioning said package in said cavities, and retention means for retaining said body in said cavity, said means including deflection means integrally hinged frontwardly on opposite first and second of said walls and rearwardly extending therefrom in elongated form to at least a position coplanar with said supporting surfaces and in spaced-apart relationship so as to be capable of deflection towards said oNe wall by the insertion of said body, said elongated form including a surface facing away from said one wall at an acute angle, said surface including finger-force releasable holding means arranged to engage one of said side surfaces of said body and including a plurality of rearwardly spaced-apart detents to accommodate bodies of differing rearwardly extending side surfaces.
Claim 2
Dependent Claim
201 words
A carrier adapted to receive an inserted dual-in-line integrated circuit package having leads and a generally flat rigid body with rearwardly extending side surfaces, said carrier comprising a one-piece insulating housing including a front face, a cavity having a generally rectangular cross-section extending rearwardly from said face and sized to receive said package, a plurality of rearwardly extending walls forming said cavity with frontwardly disposed surfaces for receiving said leads in spaced relationship and rearwardly disposed supporting surfaces for rearwardly positioning said package in said cavities, and retention means for retaining said body in said cavity, said means including deflection means integrally hinged frontwardly on opposite first and second of said walls and rearwardly extending therefrom in elongated form to at least a position coplanar with said supporting surfaces and in spaced-apart relationship so as to be capable of deflection towards said oNe wall by the insertion of said body, said elongated form including a surface facing away from said one wall at an acute angle, said surface including finger-force releasable holding means arranged to engage one of said side surfaces of said body and including a plurality of rearwardly spaced-apart detents to accommodate bodies of differing rearwardly extending side surfaces.
Claim 3
Dependent Claim
24 words
The carrier of claim 1 wherein said walls include frontwardly disposed guide surfaces arranged for predetermined lateral positioning of said package in said cavity.
Claim 4
Dependent Claim
195 words
The carrier adapted to receive an inserted dual-in-line integrated circuit package having leads and a generally flat rigid body with rearwardly extending side surfaces, said carrier comprising an insulating housing including a front face, a cavity having a generally rectangular cross section extending rearwardly from said face and sized to receive said package, first and second pairs of rearwardly extending opposite walls forming said cavity with said first pair of said walls having frontwardly disposed surfaces for receiving said leads in loose fitting relationship and rearwardly disposed, frontwardly facing surfaces for supporting said package, and retention means for retaining said body in said carrier, said means including deflection means integrally hinged on each of said second pair of opposite walls, each deflection means extending rearwardly from said each wall in elongated form and in spaced-apart relationship for deflection towards said each wall by insertion of said body, said elongated form including a surface facing away from said each wall and including finger-force releasable holding means arranged to engage one of said side surfaces of said body, said holding means including a plurality of rearwardly spaced-apart detents to accommodate bodies of differing rearwardly extending side surfaces.
Claim 5
Dependent Claim
195 words
The carrier adapted to receive an inserted dual-in-line integrated circuit package having leads and a generally flat rigid body with rearwardly extending side surfaces, said carrier comprising an insulating housing including a front face, a cavity having a generally rectangular cross section extending rearwardly from said face and sized to receive said package, first and second pairs of rearwardly extending opposite walls forming said cavity with said first pair of said walls having frontwardly disposed surfaces for receiving said leads in loose fitting relationship and rearwardly disposed, frontwardly facing surfaces for supporting said package, and retention means for retaining said body in said carrier, said means including deflection means integrally hinged on each of said second pair of opposite walls, each deflection means extending rearwardly from said each wall in elongated form and in spaced-apart relationship for deflection towards said each wall by insertion of said body, said elongated form including a surface facing away from said each wall and including finger-force releasable holding means arranged to engage one of said side surfaces of said body, said holding means including a plurality of rearwardly spaced-apart detents to accommodate bodies of differing rearwardly extending side surfaces.
Claim 6
Dependent Claim
56 words
The carrier of claim 3 wherein said cavity extends from said front face rearwardly through said housing, said deflection means is an elongated cantilever finger rearwardly extending away from said wall at an acute angle and said first pair of opposite walls includes guide surfaces arranged for predetermined lateral positioning of said package in said cavity.
Claim 7
Dependent Claim
45 words
The carrier of claim 4 wherein said housing includes a pair of peripheral flanges extending laterally and including means for cooperating with carrier handling equipment, and said cantilever finger extends rearwardly to at least a position coplanar with said support rearwardly disposed frontwardly facing surfaces.
