Abstract
Abstract The present invention provides an electrical contact which can be used in a board-mounted electrical connector and is capable of effecting resilient engagement with circuit pads on a circuit board. Electrical connector 10 has a plurality of electrical contacts 50 inside a housing 20. Each of the electrical contacts 50 has a first plate member 62 and a second plate member 63 which are formed by folding at one end on an engaging side. The first plate member 62 has a press-fitting section 53 and a resilient contact section 52 extending at an inclined angle. The second plate member 63 includes a pressing shoulder 66 used during press-fitting into a cavity of the housing. When the housing 20 is mounted on a circuit board, the contact sections 52 of the electrical contacts 50 flex resiliently at the bottom side of the housing 20, and termination sections 54 resiliently engage circuit pads on the circuit board.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
120 words
An electrical contact for insertion into and retention in a cavity of a dielectric housing, comprising a first plate member and a second plate member connected together at one end by folding the plate members back upon one another so that the plate members are disposed at a slight angle; an inclined-contact section at an outer end of the first plate member; and a securing section provided by the first plate member adjacent the inclined-contact section so that the securing section engages a wall of the cavity when the electrical contact is inserted into the cavity thereby securing the electrical substantially rigid contact in the cavity and causing the plate members to extend along one another defining a contact member.
Claim 2
Dependent Claim
120 words
An electrical contact for insertion into and retention in a cavity of a dielectric housing, comprising a first plate member and a second plate member connected together at one end by folding the plate members back upon one another so that the plate members are disposed at a slight angle; an inclined-contact section at an outer end of the first plate member; and a securing section provided by the first plate member adjacent the inclined-contact section so that the securing section engages a wall of the cavity when the electrical contact is inserted into the cavity thereby securing the electrical substantially rigid contact in the cavity and causing the plate members to extend along one another defining a contact member.
Claim 3
Dependent Claim
20 words
The electrical contact as claimed in claim 1, wherein said inclined-contact section includes a first portion and a second portion.
Claim 4
Dependent Claim
22 words
The electrical contact as claimed in claim 2, wherein the second portion is inclined at a greater angle than said first portion.
Claim 5
Dependent Claim
16 words
The electrical contact as claimed in claim 1, wherein the securing section includes spaced projecting members.
Claim 6
Dependent Claim
24 words
The electrical contact as claimed in claim 2, wherein an outer end of said second portion defines a termination section having an arcuate configuration.
Claim 7
Dependent Claim
124 words
An electrical connector, comprising a dielectric housing having contact-receiving cavities; electrical contacts disposed in the contact-receiving cavities, each of the electrical contacts including a first plate member and a second plate member connected at one end and extending along one another within the contact-receiving cavity thereby defining a substantially rigid contact member for electrical engagement with a mating contact, an inclined-contact section at an outer end of the first plate member including a termination section at a free end thereof extending outwardly from a bottom surface of the dielectric housing, and a securing section on the contact member engaging a wall of the contact-receiving cavity thereby securing the electrical contact within the contact-receiving cavity and causing the plate members to extend along one another.
Claim 8
Dependent Claim
124 words
An electrical connector, comprising a dielectric housing having contact-receiving cavities; electrical contacts disposed in the contact-receiving cavities, each of the electrical contacts including a first plate member and a second plate member connected at one end and extending along one another within the contact-receiving cavity thereby defining a substantially rigid contact member for electrical engagement with a mating contact, an inclined-contact section at an outer end of the first plate member including a termination section at a free end thereof extending outwardly from a bottom surface of the dielectric housing, and a securing section on the contact member engaging a wall of the contact-receiving cavity thereby securing the electrical contact within the contact-receiving cavity and causing the plate members to extend along one another.
Claim 9
Dependent Claim
25 words
The electrical connector as claimed in claim 6, wherein the housing has a protruding section along which the contact members of the electrical contacts extend.
Claim 10
Dependent Claim
24 words
The electrical connector as claimed in claim 6, wherein the contact-receiving cavities have recesses including inclined surfaces in which the inclined-contact sections are disposed.
Claim 11
Dependent Claim
18 words
The electrical connector as claimed in claim 8, wherein the inclined-contact sections include first portions and second portions.
Claim 12
Dependent Claim

Claim 14
Dependent Claim
28 words
The electrical connector as claimed in claim 6, wherein the housing has opposing sides and the termination sections do not extend beyond the sides of the dielectric housing.
Claim 15
Dependent Claim

Claim 16
Dependent Claim
20 words
The electrical connector as claimed in claim 13, wherein the projecting members are generally perpendicular to said first plate member.
Claim 17
Dependent Claim
169 words
An electrical contact for insertion into and retention in a cavity of a dielectric housing having a protruding section, comprising a first plate member and a second plate member connected together at one end by folding the plate members back upon one another so that the first plate member is disposed at an angle with respect to the second plate member; an inclined-contact section at an outer end of the first plate member; and a securing section on the first plate member at a junction of the first plate member and the inclined-contact section so that when the electrical contact is inserted into the cavity, the second plate member extends along a surface of the protruding section, the securing section engages a wall of the cavity thereby securing the electrical contact in the cavity, causing the first plate member to extend along the second plate member with the first plate member defining a contact member and the inclined contact section being inclined with respect to the second plate member.
Claim 18
Dependent Claim
