Abstract
Abstract A low profile socket for receiving an electronic multi-pin package is characterized by having a housing including a plurality of elongated channels, and a corresponding plurality of terminal pins. Each terminal pin includes a receptable portion that is disposed within a channel in the housing, and furthermore includes a post portion which extends from one side of the housing. Each channel includes a flexible membrane portion having an aperture through which the post of the terminal pin extends, with the aperture of the flexible membrane portion being smaller in cross-section than the cross-section of the post. Accordingly, when the terminal pin is fully inserted in the housing, the flexible membrane portion is flexed or stretched, and thereby forms a fluid type seal with the terminal post, thereby restricing liquid or foam flux and solder from entering the channel of the socket when the socket is being connected, such as by wave soldering, to the associated printed circuit board.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
A socket for receiving an electronic multi-pin package comprising an elongated housing having the plurality of channels extending therethrough and a plurality of terminals; each terminal including (1) a post portion received within a respective one of said channels and extending from one side of the housing, and (2) a receptacle portion disposed within said respective channel for engaging a pin of said multi-pin package; each said channel in said housing defined by (1) rigid upstanding wall portions for engaging the sides of said receptacle portion of the terminal, and (2) a flexible membrane base having an aperture therein, with the cross-section of said aperture being less than the cross-section of said terminal post portion whereby, when the terminal post portion is fully assembled in said channel, the membrane base thereof deforms downwardly to sealingly engage the terminal.
Claim 2
Dependent Claim
138 words
A socket for receiving an electronic multi-pin package comprising an elongated housing having the plurality of channels extending therethrough and a plurality of terminals; each terminal including (1) a post portion received within a respective one of said channels and extending from one side of the housing, and (2) a receptacle portion disposed within said respective channel for engaging a pin of said multi-pin package; each said channel in said housing defined by (1) rigid upstanding wall portions for engaging the sides of said receptacle portion of the terminal, and (2) a flexible membrane base having an aperture therein, with the cross-section of said aperture being less than the cross-section of said terminal post portion whereby, when the terminal post portion is fully assembled in said channel, the membrane base thereof deforms downwardly to sealingly engage the terminal.
