Abstract

Abstract A right angle header connector (10) is disclosed for mounting on a surface of a printed circuit board (44) wherein the connector includes a dielectric housing (12) having a bottom mounting face (28), a forward mating face (24) and a rearward terminating face (26). A plurality of contact passages (36, 38) are provided in the housing and extending between the forward mating face and the rearward terminating face and defining top and bottom rows and vertical columns of passages, with at least a pair of passages in each column. A plurality of terminals (4) are secured in the passages and have contact sections (16) projecting from the forward mating face and terminating sections (18) projecting from the rearward terminating face connectable to corresponding circuit traces (42) on the printed circuit board. The terminating sections of the contacts in the bottom row (18b) thereof are formed at a first angle, and the terminating sections of the contacts in the top row thereof (18a) are formed at a relatively smaller angle for connection to corresponding rows of circuit traces on the printed circuit board spaced different distances from the rearward terminating face of the housing. The resultant configuration allows the terminals of both rows to have substantially equal electrical pathlengths and therefore eliminates signal delay in high speed applications. Furthermore, the rearward terminating face of the housing compensates for the relatively smaller bending moment of the top row of terminals by recessing the upper row of terminal passages thereby optimizing lead coplanarity.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 286 words
In a right angle electrical connector (10) for mounting on a surface of a printed circuit board (44) wherein the connector includes a dielectric housing (12) having a bottom mounting face (28), a forward mating face (24) and rearward terminating face (26), a plurality of terminal passages (36, 38) in the housing and extending between the forward mating face (24) and the rearward terminating face (26) and defining top and bottom rows and vertical columns of passages with at least a pair of passages in each column, and a plurality of conductive terminals (14) secured in the passages each having a contact section (16) projecting from said forward mating face and a terminating section (18) projecting from the rearward terminating face including a board engaging end (40) connectable to corresponding circuit traces (42) on the printed circuit board at a given board angle, the board angle of the terminating sections of the top row (18a) being greater than the board angle of the terminating sections of the bottom row (18b), each terminating section defining a mounting arm deflectable about a point generally defined between the contact section and the terminating section in response to a force applied to the board engaging end of the terminal by the printed circuit board characterized in that: the points of deflection of the mounting arms of the terminating sections in the top row being offset from the points of deflection of the mounting arms of the terminating sections in the bottom row in the direction of the forward mating face of the housing whereby the bending moments of the mounting arms in the top row are substantially equal to the bending moments of the mounting arms in the bottom row.
Claim 2
Dependent Claim 66 words
In an electrical connector as set forth in claim 1, wherein the terminating sections of the contacts in the bottom row thereof project from the rearward terminating face of the housing generally in the planes of the respective columns of contacts and the terminating sections of the contacts in the top row thereof project from the rearward terminating face of the housing offset from said planes.
Claim 3
Dependent Claim 40 words
The electrical connector of claim 1 wherein the points of deflection of the mounting arms of the terminating sections in the top and bottom rows are defined by the portion of the rearward terminating face superjacent the respective terminal passage.
Claim 4
Dependent Claim 23 words
The electrical connector of claim 1 wherein the length of the conductive terminals (14) of said top and bottom rows are substantially equal.
Claim 5
Dependent Claim 214 words
In a right angle electrical connector (10) for mounting on a surface of a printed circuit board (44) wherein the connector includes a dielectric housing (12) having a bottom mounting face (28), a forward mating face (24) and rearward terminating face (26), a plurality of terminal passages (36, 38) in the housing and extending between the forward mating face (24) and the rearward terminating face (26) and defining top and bottom rows and vertical columns of passages with at least a pair of passages in each column, and a plurality of conductive terminals (4) secured in the passages, each having a contact section (16) projecting from said forward mating face and a terminating section (18) projecting from the rearward terminating face including a board engaging end (40) connectable to corresponding circuit traces on the printed circuit board at a given board angle, the board angle of the terminating sections of the top row (18a) being greater than the board angle of the terminating sections of the bottom row (18b), characterized in that: the conductive terminals of said top and bottom rows being of substantially the same overall length whereby an electrical signal travelling through each of said terminals will travel approximately the same distance in the same amount of time thereby eliminating signal delay.
Claim 6
Dependent Claim 66 words
In an electrical connector as set forth in claim 4, wherein the terminating sections of the contacts in the bottom row thereof project from the rearward terminating face of the housing generally in the planes of the respective columns of contacts, and the terminating sections of the contacts in the top rows thereof project from the rearward terminating face of the housing offset from said planes.
Claim 7
Dependent Claim 73 words
In an electrical connector as set forth in claim 4, wherein the terminating sections of the contacts in the bottom row thereof project from the rearward terminating face of the housing offset to one side of the planes of the respective columns of contacts, and the terminating sections of the contacts in the top row thereof project from the rearward terminating face of the housing offset to the opposite side of said planes.
