Abstract
Abstract The electrical connector comprises a housing having contact receiving passages with contacts disposed therein. Recesses are disposed along a mounting face of the connector and are defined by walls therealong. The recesses are in communication with the contact receiving passages. A rigid ground bar is disposed along sidewalls of the housing. Chip capacitors are positioned in the recesses to have one electrode electrically connected with the contact and the other electrode to be electrically connected with the ground bar. The chip capacitor provides a low impedance pathway for EMI from the contact to the ground.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
173 words
An electrical connector, comprising: a housing having sidewalls, mounting flanges, a mounting face, an interior mating cavity, a contact receiving passageway, and a recess disposed along the mounting face, the recess being defined by walls along the mounting face, the recess being open to the mounting face and towards sides of the housing, the recess also being in communication with the contact receiving passageway; a contact being secured within the contact receiving passageway, the contact having a mating portion, a rigid intermediate portion and a mounting portion; a rigid ground bar extending lengthwise along the housing and secured thereto, the ground bar being in communication with the recess along the sides of the housing; and a chip capacitor having two electrodes and being disposed in the recess with one of said electrodes in electrical contact with the contact and the other of said electrodes being in electrical contact with said ground bar; whereby the capacitor is secured within the recess between the rigid intermediate portion of the contact and the rigid ground bar.
Claim 2
Dependent Claim
173 words
An electrical connector, comprising: a housing having sidewalls, mounting flanges, a mounting face, an interior mating cavity, a contact receiving passageway, and a recess disposed along the mounting face, the recess being defined by walls along the mounting face, the recess being open to the mounting face and towards sides of the housing, the recess also being in communication with the contact receiving passageway; a contact being secured within the contact receiving passageway, the contact having a mating portion, a rigid intermediate portion and a mounting portion; a rigid ground bar extending lengthwise along the housing and secured thereto, the ground bar being in communication with the recess along the sides of the housing; and a chip capacitor having two electrodes and being disposed in the recess with one of said electrodes in electrical contact with the contact and the other of said electrodes being in electrical contact with said ground bar; whereby the capacitor is secured within the recess between the rigid intermediate portion of the contact and the rigid ground bar.
Claim 3
Dependent Claim
36 words
The connector of claim 1, wherein an end cap is disposed over the mounting flange, the end cap having extensions which are electrically connected to the ground bar to provide ground connection to the circuit board.
Claim 4
Dependent Claim
21 words
The connector of claim 1, wherein the housing has a slot disposed therealong, the ground bar being secured within the slot.
Claim 5
Dependent Claim
43 words
The connector of claim 3, wherein the ground bar has a securing portion which is secured within the slot, a mounting portion which is perpendicular to the securing portion, and an angled portion which extends from the securing portion to the mounting portion.
Claim 6
Dependent Claim
51 words
The connector of claim 4, wherein a silicon rubber pad is secured along the mounting face to secure the chip capacitor within the recess, the silicon rubber pad having a through hole which the contact extends through, the silicon rubber pad being secured to the mounting portion of the ground bar.
Claim 7
Dependent Claim
25 words
The connector of claim 1, wherein the mounting portion of the contact has resilient legs for engaging with a through hole in a circuit board.
Claim 8
Dependent Claim
33 words
The connector of claim 1, wherein the sidewalls of the housing have an overhang which is directed toward the mounting face, the overhang having a slot therealong to secure the ground bar therein.
Claim 9
Dependent Claim
20 words
The connector of claim 7, wherein walls extend downwardly from the overhang to define the recess along the mounting face.
Claim 10
Dependent Claim
30 words
The connector of claim 8, wherein contacts are disposed in the housing in two rows, a center wall extends along the mounting face to separate adjacent recesses from each other.
Claim 11
Dependent Claim
21 words
The connector of claim 1, wherein the housing is mounted on a circuit board and the mating face extends upwardly therefrom.
Claim 12
Dependent Claim
28 words
The connector of claim 10, wherein the mounting portion of the contact is a through hole contact, the circuit board having through holes to receive the mounting portion.
Claim 13
Dependent Claim
81 words
The connector of claim 1, wherein an elastomeric pad is disposed along the mounting face to retain the chip capacitor within the recess, whereby upon mounting of the connector to a circuit board, the elastomeric pad provides a force against the chip capacitor which is directed toward the ground bar, the ground bar then directs the force toward the contact thereby providing good electrical connection between the chip capacitor and the ground bar, and between the chip capacitor and the contact.
Claim 14
Dependent Claim
22 words
The connector of claim 12, wherein the chip capacitors are disposed within the recess at an angle with respect to the contact.
