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: 5

Claim 1

Independent Claim 210 words

A surface mountable electrical connector (10) for use with a circuit board (70) having an outer row (74) of trace termini (76) and an inner row (82) of trace termini (84) closely spaced therefrom on the mounting surface (72) of said board (70), said connector (10) including a dielectric housing (12) having at least one row of electrical terminal members (30) extending therebetween, said terminal members (30) being arranged adjacent to each other and in a dense array in said at least one row, said terminal members (30) including elongate arm portions extending from said housing (12) to surface mount contact sections (38) at free ends thereof associated with a respective one of said trace termini (76,84) of said circuit board (70), the connector (10) being characterized in that: each said terminal member (30) associated with said outer row (74) of termini includes a portion (40) immediately adjacent said surface mount contact section (38) that is abruptly directed away from said mounting surface (72)of said circuit board (70) at least a selected distance above the spacing between said outer and inner rows (74,82) of said termini (76,84) to minimize wicking of solder thereat thereby preventing solder from wicking to closely adjacent ones of said termini (84) of said inner row.

Claim 2

Dependent Claim 218 words

A surface mountable electrical connector (10) for use with a circuit board (70) having at least one row (82) of trace termini (84) on the mounting surface (72) of said board (70), said connector (10) including a dielectric housing (12) having at least one row of electrical terminal members (46) therein, said terminal members (46) being arranged adjacent to each other and in a dense array in said at least one row, said terminal members (46) including elongate arm portions (52) extending from said housing (12) to surface mount contact sections (54) at free ends thereof associated with a respective one of said trace termini (84) of said circuit board (70) the connector (10) being characterized in that: each said terminal member (46) has a registration portion (56) proximate a said free end thereof and directed upwardly away from the mounting surface (72) of the board (70) said registration portion (56) being receivable in an associated recess (20) extending into said housing (12), at the mounting face (18) thereof, thereby maintaining the registration of said elongate arm portions (52) and the accurate spacing of said surface mount contact sections (54) during handling and mounting of said connector (10) to said board (70) and preventing inadvertent engagement with closely spaced contact sections and misalignment with corresponding trace termini (84).

Claim 3

Dependent Claim 43 words

The surface mountable electrical connector of claim 2 wherein said terminal member (46) is a ground terminal member, said ground terminal member including two elongate arm portions (52) extending in opposite directions from said housing (12), each having a respective registration portion (54).

Claim 4

Dependent Claim 29 words

The surface mountable electrical connector (10) of claim 3 wherein each said ground terminal member (46) includes a board support section (58) intermediate said two elongate arm portions (52).

Claim 5

Dependent Claim 26 words

The surface mountable electrical connector (10) of claim 4 wherein said board support section (58) is electrically connectable to ground termini (90) on said board (70).
