Abstract

Abstract The invention is teaching an edge connector (10) for a printed circuit board (13) having a mating edge and a plurality of signal and ground contact pads (17a, 17b) adjacent the edge, the connector including an elongated dielectric housing (16) having a board-receiving slot (12) for receiving the mating edge of the printed circuit board, a plurality of signal terminals (28) and a plurality of ground terminals (30) mounted on the housing, the terminals having body portions (32, 48) located in the housing and spring contact portions (34, 50) extending into the slot for contacting respective ones of the contact pads on the printed circuit board, said signal terminals (28) and ground terminals (30) being positioned in an alternating array along each side of the slot means, with each signal terminal being aligned with a ground terminal or each ground terminal being aligned with a signal terminal on opposite transverse sides of the slot, and the ground terminals having significantly larger transverse areas than the signal terminals.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 166 words
An edge connector (10) for a printed circuit board (13) having a mating edge and a plurality of signal and ground contact pads (17a, 17b) adjacent the edge, the connector including an elongated dielectric housing (16) having a board-receiving slot (12) for receiving the mating edge of the printed circuit board, a plurality of signal terminals (28) and a plurality of ground terminals (30) mounted on the housing, the terminals having body portions (32, 48) located in the housing and spring contact portions (34, 50) extending into the slot for contacting respective ones of the contact pads on the printed circuit board, characterized in that said signal terminals (28) and ground terminals (30) being positioned in an alternating array along each side of the slot means, with each signal terminal being aligned with a ground terminal or each ground terminal being aligned with a signal terminal on opposite transverse sides of the slot, and the ground terminals having significantly larger transverse areas than the signal terminals.
Claim 2
Dependent Claim 29 words
An edge connector as set forth in claim 1, wherein the body portions of the grounds terminals have significantly larger areas than the body portions of the signal terminals.
Claim 3
Dependent Claim 61 words
An edge connector as set forth in claims 1 or 2, wherein the body portions of the ground terminals include base portions (52), mounting barbs (54) projecting from the base portions for securing the terminals in the housing and enlarged surface area portions (56) projecting from the base portions, with the spring contacts portions projecting from the enlarged surface area portions.
Claim 4
Dependent Claim 68 words
An edge connector as set forth in claims 1, 2 or 3, wherein the connector is adapted for mounting on a printed circuit board (11) having a common ground circuit and a plurality of circuit traces forming portions of the common ground circuit, and wherein said ground terminals have at least two grounding portions (57, 60) for engaging the common ground circuit to establish a multiple-point contact therewith.
Claim 5
Dependent Claim 35 words
An edge connector as set forth in claim 4, wherein an area of the printed circuit board, between the points of contact is left open to facilitate routing various other circuit traces on the board.
Claim 6
Dependent Claim 26 words
An edge connector as set forth in one of claims 1 to 5, wherein said terminals comprise stubs which can be trimmed to a given size.
Claim 7
Dependent Claim 28 words
An edge connector as set forth in one of claims 1 to 6, wherein said mechanically non-functional sections comprise stubs which can be broken away from the terminals.
Claim 8
Dependent Claim 36 words
An edge connector as set forth in one of claims 1 to 7, wherein said mounting portion includes a mounting leg located in a recess (26a) in the housing for securing the terminals in the housing.
Claim 9
Dependent Claim 22 words
An edge connector as set forth in claim 8, wherein the contact portions and the mounting portions project from the body portions.
Claim 10
Dependent Claim 53 words
An edge connector as set forth in claim 9, wherein said mounting portions and said contact portions project from one side of the body portions, the mounting portions being located outside the contact portions and said slot, and said mechanically non-functional sections include stubs projecting from the body portions inside the contact portions.
