Abstract
Abstract A surface mountable electrical connector 10 for use with a circuit board 70 of the type having one or more rows 74,82 of closely spaced trace termini 76,84 on the mounting surface 72 of the board 70, the connector 10 including a housing 12 having one or more rows of closely spaced electrical terminal members 30,46 therein. The terminal members 30,46 include elongate arm portions 36,52 extending from the housing 12 to surface mount contact sections 38,54 at free ends thereof. Each terminal associated with an outer row 74 of circuit board termini 76 includes a portion immediately adjacent and inwardly from the contact section 38, which is abruptly directed away from the mounting surface 72 to minimize wicking of solder to a nearby inner row termini 84. Some terminal members 46 include a registration portion 56 proximate free ends thereof and directed upwardly away from the mounting surface 72 of the board 70, to be received in an associated recess 20 extending into the mounting face 18 of the housing 12, thereby maintaining the registration of the elongate arms 52 and the accurate spacing of the surface mount contact sections 54 during handling and mounting.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
261 words
A surface mountable electrical connector for use with a circuit board of the type having an outer row of trace termini and an inner row of trace termini closely spaced therefrom on the mounting surface of said board, said connector comprising a dielectric housing having a mounting face and a mating face and at least one row of electrical terminal members extending therebetween, said terminal members arranged adjacent to each other and in a dense array in said at least one row with some of said terminal members being associated with said outer row of termini and others of said terminal members being associated with said inner row of termini, said terminal members including elongate arm portions extending from said housing and generally parallel to said mounting face thereof, at least each said terminal members associated with said outer row of termini including an intermediate portion extending at an angle from said elongate arm portion and generally away from said mounting face, said intermediate portion concluding in a surface mount contact section that extends generally parallel to said mounting face, said intermediate portion defining a surface facing said inner row of trace termini that is abruptly directed away from said mounting surface of said circuit board at least a selected distance above the spacing between said outer and inner rows of said termini to provide clearance above solder used to solder said surface mount contact section to a respective trace termini in said outer row thereby preventing solder from wicking to closely adjacent ones of said termini of said inner row.
Claim 2
Dependent Claim
261 words
A surface mountable electrical connector for use with a circuit board of the type having an outer row of trace termini and an inner row of trace termini closely spaced therefrom on the mounting surface of said board, said connector comprising a dielectric housing having a mounting face and a mating face and at least one row of electrical terminal members extending therebetween, said terminal members arranged adjacent to each other and in a dense array in said at least one row with some of said terminal members being associated with said outer row of termini and others of said terminal members being associated with said inner row of termini, said terminal members including elongate arm portions extending from said housing and generally parallel to said mounting face thereof, at least each said terminal members associated with said outer row of termini including an intermediate portion extending at an angle from said elongate arm portion and generally away from said mounting face, said intermediate portion concluding in a surface mount contact section that extends generally parallel to said mounting face, said intermediate portion defining a surface facing said inner row of trace termini that is abruptly directed away from said mounting surface of said circuit board at least a selected distance above the spacing between said outer and inner rows of said termini to provide clearance above solder used to solder said surface mount contact section to a respective trace termini in said outer row thereby preventing solder from wicking to closely adjacent ones of said termini of said inner row.
Claim 3
Dependent Claim
49 words
The surface mountable electrical connector of claim 1 wherein said intermediate portion of each said terminal associated with said outer row of circuit board termini is of sufficient length to elevate said elongate portion above said circuit board a distance that is greater than the thickness of the terminal.
Claim 4
Dependent Claim
207 words
A surface mountable electrical connector of the type having terminal members with elongate arm portions with surface mounted contact sections for use with a circuit board of the type having at least one row of trace termini on the mounting surface of said board, said connector comprising a dielectric housing having a mounting face and a mating face and at least one row of electrical terminal members extending therebetween, said terminal members arranged adjacent to each other and in a dense array in said at least one row, said terminal members including elongate arm portions extending from said housing to surface mount contact sections at free ends thereof associated with a respective one of said trace termini of said circuit board, each said terminal member having a registration portion directed upwardly away from the mounting surface of the board, said registration portion being receivable in an associated recess extending into said mounting face of said housing and inwardly from a side surface of said housing, thereby maintaining the registration of said elongate arms and the accurate spacing of said surface mount contact sections during handling and mounting of said connector to said board and preventing inadvertent engagement with closely spaced contacts and misalignment with corresponding trace termini.
Claim 5
Dependent Claim
207 words
A surface mountable electrical connector of the type having terminal members with elongate arm portions with surface mounted contact sections for use with a circuit board of the type having at least one row of trace termini on the mounting surface of said board, said connector comprising a dielectric housing having a mounting face and a mating face and at least one row of electrical terminal members extending therebetween, said terminal members arranged adjacent to each other and in a dense array in said at least one row, said terminal members including elongate arm portions extending from said housing to surface mount contact sections at free ends thereof associated with a respective one of said trace termini of said circuit board, each said terminal member having a registration portion directed upwardly away from the mounting surface of the board, said registration portion being receivable in an associated recess extending into said mounting face of said housing and inwardly from a side surface of said housing, thereby maintaining the registration of said elongate arms and the accurate spacing of said surface mount contact sections during handling and mounting of said connector to said board and preventing inadvertent engagement with closely spaced contacts and misalignment with corresponding trace termini.
Claim 6
Dependent Claim
39 words
The surface mountable electrical connector of claim 3 wherein said terminal member is a ground terminal member, said ground terminal member including two elongate arm portions extending in opposite directions from said housing, each having a respective registration portion.
Claim 7
Dependent Claim
25 words
The surface mountable electrical connector of claim 4 wherein each said ground terminal member includes a board support section intermediate said two elongate arm portions.
Claim 8
Dependent Claim
22 words
The surface mountable electrical connector of claim 5 wherein said board support section is electrically connectable to ground termini on said board.
