Abstract
Abstract An electrical header (40) comprises an insulating block (42) having contact elements (44) thereon which are made from bent drawn wire, each contact element (44) comprising a contact portion (46) extending across one side (41) of the block (46) and a leg (50) for insertion into a hole (H) in a printed circuit board (PCB). An electrical jack (2) for mating with the header (40) has an insulating housing (4) with a cavity (b 6) for receiving a mating plug. Terminals (10) secured in a wall (12) of the housing (4) have contact springs for engaging contacts of the plug and contact tails (18) with contact loops (24) which are bowed away from the cavity wall (12) to engage the contact portions (46) of the header (40) when it has been mated with the jack (2). This construction of the jack and header avoids the need to taper ends of the wires from which the contact elements are made, for mating with the contact tails.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
An electrical jack and header assembly, wherein the jack comprises an insulating housing defining a cavity for receiving an electrical plug, and a row of electrical terminals secured to a wall of the cavity and each having a contact spring extending obliquely thereinto for engaging a respective electrical contact on the plug, and a contact tail depending from said wall, the header comprising an insulating block having securing thereto to a row of contact elements each having on one side of the block, a contact portion, and on the opposite side of the block a leg for insertion in a hole in a printed circuit board, the jack being matable with the header to cause each contact tail of the jack to engage a respective contact portion of the header; wherein each contact tail terminates in a contact surface which is bowed in a direction perpendicular to, and away from, said wall, and in that each contact portion extends across said one side of the insulating block, the leg of each contact element depends from the opposite end of the contact portion thereof to a next adjacent leg of the header, whereby the insertion legs depend from the header in two spaced rows.
Claim 2
Dependent Claim
203 words
An electrical jack and header assembly, wherein the jack comprises an insulating housing defining a cavity for receiving an electrical plug, and a row of electrical terminals secured to a wall of the cavity and each having a contact spring extending obliquely thereinto for engaging a respective electrical contact on the plug, and a contact tail depending from said wall, the header comprising an insulating block having securing thereto to a row of contact elements each having on one side of the block, a contact portion, and on the opposite side of the block a leg for insertion in a hole in a printed circuit board, the jack being matable with the header to cause each contact tail of the jack to engage a respective contact portion of the header; wherein each contact tail terminates in a contact surface which is bowed in a direction perpendicular to, and away from, said wall, and in that each contact portion extends across said one side of the insulating block, the leg of each contact element depends from the opposite end of the contact portion thereof to a next adjacent leg of the header, whereby the insertion legs depend from the header in two spaced rows.
Claim 3
Dependent Claim
30 words
An assembly according to claim 1 wherein the contact surface of each contact tail is defined by an end portion thereof which has been reversely bent to form a loop.
Claim 4
Dependent Claim
44 words
An assembly according to claim 1 wherein there depends from the housing pair of latch arms for latching engagement with respective latch members on opposite ends of the insulating block, and a latching member for latching engagement in an opening in the circuit board.
Claim 5
Dependent Claim
34 words
An assembly according to claim 1 wherein there depend from the housing a pair of spaced arms having inwardly projecting end portions for insertion through notches in opposite undercut edges of the insulating block.
Claim 6
Dependent Claim
203 words
An electrical jack and header assembly, wherein the jack comprises an insulating housing defining a cavity for receiving an electrical plug, and a row of electrical terminals secured to a wall of the cavity and each having a contact spring extending obliquely thereinto for engaging a respective electrical contact on the plug, and a contact tail depending from said wall, the header comprising an insulating block having secured thereto a row of contact elements each having on one side of said block, a contact portion, and on the opposite side of said block a leg for insertion in a hole in a printed circuit board, the jack being matable with the header to cause each contact tail of the jack to engage a respective contact portion of the header; wherein each contact tail terminates in a contact surface which is bowed in a direction perpendicular to, and away from, said wall, and in that each contact portion extends across said one side of the insulating block, a pair of latch arms depends from the housing for latching engagement with respective latch members on opposite ends of the insulating block, and a latching member for latching engagement is an opening in the circuit board.
Claim 7
Dependent Claim
203 words
An electrical jack and header assembly, wherein the jack comprises an insulating housing defining a cavity for receiving an electrical plug, and a row of electrical terminals secured to a wall of the cavity and each having a contact spring extending obliquely thereinto for engaging a respective electrical contact on the plug, and a contact tail depending from said wall, the header comprising an insulating block having secured thereto a row of contact elements each having on one side of said block, a contact portion, and on the opposite side of said block a leg for insertion in a hole in a printed circuit board, the jack being matable with the header to cause each contact tail of the jack to engage a respective contact portion of the header; wherein each contact tail terminates in a contact surface which is bowed in a direction perpendicular to, and away from, said wall, and in that each contact portion extends across said one side of the insulating block, a pair of latch arms depends from the housing for latching engagement with respective latch members on opposite ends of the insulating block, and a latching member for latching engagement is an opening in the circuit board.
Claim 8
Dependent Claim
30 words
An assembly according to claim 5 wherein the contact surface of each contact tail is defined by an end portion thereof which has been reversely bent to form a loop.
