Abstract
Abstract A multiple male pin electrical header is provided for connection to the surface of a printed circuit board. No header components need extend entirely through the board. The header comprises an integral and electrically insulating body member; and the plurality of male pin connectors extend through the body member. The pins have tail portions adapted to electrically contact pads or other surfaces of a printed circuit board. Pin head portions extend upwardly for connection with another electrical connector. The header body portion is formed to define a plurality of pin cavities, each cavity being shaped to expose only an individual male pin connector for contact by test probe. These cavities are shaped to discourage simultaneous test probe shorting contact across a plurality of connector pins. The body member is geometrically configured to provide recesses between the pin members, so that the body member can be broken apart at any one of the recesses to provide a multiple pin electrical header of desired extent.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
A multiple male pin electrical header for connection to the surface of a printed circuit board, the header comprising, in combination, an integral, electrically insulating body member, and a plurality of solid, generally cylindrical male pin connectors extending at least partly through the body member, at least one pin having a tail portion adapted to electrically contact the surface of a printed circuit board and being provided with a pad tip recess opening in the direction of the axis of the cylindrical male pin and adapted to temporarily receive in a recess a reflow solder pellet oriented parallel to the surface of the underlying printed circuit board, the pin further having a head portion adapted for connection with another electrical connector, the insulating header body portion being formed to define a plurality of pin cavities, each cavity being shaped to expose a single individual solid male pin connector side for contact by a test probe, yet discourage simultaneous test probe shorting contact with a plurality of connector pins or a plurality of single connector pin surfaces.
Claim 2
Dependent Claim
176 words
A multiple male pin electrical header for connection to the surface of a printed circuit board, the header comprising, in combination, an integral, electrically insulating body member, and a plurality of solid, generally cylindrical male pin connectors extending at least partly through the body member, at least one pin having a tail portion adapted to electrically contact the surface of a printed circuit board and being provided with a pad tip recess opening in the direction of the axis of the cylindrical male pin and adapted to temporarily receive in a recess a reflow solder pellet oriented parallel to the surface of the underlying printed circuit board, the pin further having a head portion adapted for connection with another electrical connector, the insulating header body portion being formed to define a plurality of pin cavities, each cavity being shaped to expose a single individual solid male pin connector side for contact by a test probe, yet discourage simultaneous test probe shorting contact with a plurality of connector pins or a plurality of single connector pin surfaces.
Claim 3
Dependent Claim
25 words
A header according to claim 1 wherein said cavities are each defined by at least one wall extending horizontally outwardly beyond said male pin member.
Claim 4
Dependent Claim
41 words
A multiple pin electrical header according to claim 1 wherein at least one male pin member is provided with a body portion including a mediate formation adapted to secure said pin to and at least partly within the header body portion.
Claim 5
Dependent Claim
66 words
A multiple pin electrical header according to claim 1 further including standoff enbossments extending from said body portion whereby, when said header is mounted upon the printed circuit board, said pin tail portions are located at positions spaced above said printed circuit board, so as to permit cleaning solution to flow freely under and around the header pins and circuit board and thereby remove solder flux.
Claim 6
Dependent Claim
66 words
A multiple pin electrical header according to claim 1 wherein said pins are provided with elongated feet extending outwardly and downwardly from said pins to positions below the body member, whereby, said body member is assembled to said printed circuit board, said extending feet contact the printed circuit board with a positive force encouraging good electrical contact between said pin foot and said printed circuit board.
Claim 7
Dependent Claim
75 words
A header according to claim 1 wherein said body member mounts a plurality of said male pin members in a regular array of at least one column, and wherein said body member is provided with recesses in registry with said column to facilitate the detachment of one portion of the integral body member from another portion and thereby provide the header user with a multi-pin male connector member of desired size and number of pins.
Claim 8
Dependent Claim
28 words
A header member according to claim 6 wherein said body portion recesses are regularized to permit a plurality of connectors to be interlockingly nested together in a stack.
Claim 9
Dependent Claim
46 words
A multiple pin electrical header according to claim 1 further including at least one guide lug extending outwardly from said body portion for engagement in a mating recess provided in the printed circuit board to accurately locate the header on the circuit board during header/board assembly.
Claim 10
Dependent Claim
32 words
A multiple pin electrical header according to claim 8 wherein said guide lug is sized to extend less than entirely through said printed circuit board, to provide an uninterrupted reverse board surface.
