Abstract
Abstract An electrical contact comprising a holding section (2) formed of opposing side plates (6) bent from a bottom plate (5), a contact section (3) extending outwardly from the holding section (2) for electrical connection with a circuit board, a wire-connection section (4) between the side plates (6) for electrical connection to an insulated electrical wire (30), projections (18) at the sides of the wire-connection section (4) disposed in projection-receiving holes (8) in the side plates (6), and the side plates (6) having thermal-insulation holes (9, 9') adjacent the projection-receiving holes (8) to dissipate heat conducted along the contact section (3) and holding section (2) when the contact section (3) is soldered to the circuit board to obviate the melting or softening of the insulation of the electrical wire (30) in the wire-connection section (4).

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
145 words
An electrical contact comprising a holding section formed of opposing side plates bent from a bottom plate, a contact section extending outwardly from said holding section for electrical connection with a circuit board, a wire-connection section between said side plates for electrical connection to an insulated electrical wire and projections at the sides of said wire-connection section disposed in projection-receiving holes in said side plates, characterized in that said side plates have thermal-insulation holes adjacent said projection-receiving holes to dissipate heat conducted along the contact section and holding section when the contact section is soldered to the circuit board to obviate the melting or softening of the insulation of the electrical wire in the wire-connection section, wherein at least one of said thermal insulation holes has at least one edge that is continuous with an edge of at least one of said projection receiving holes.
Claim 2
Dependent Claim
145 words
An electrical contact comprising a holding section formed of opposing side plates bent from a bottom plate, a contact section extending outwardly from said holding section for electrical connection with a circuit board, a wire-connection section between said side plates for electrical connection to an insulated electrical wire and projections at the sides of said wire-connection section disposed in projection-receiving holes in said side plates, characterized in that said side plates have thermal-insulation holes adjacent said projection-receiving holes to dissipate heat conducted along the contact section and holding section when the contact section is soldered to the circuit board to obviate the melting or softening of the insulation of the electrical wire in the wire-connection section, wherein at least one of said thermal insulation holes has at least one edge that is continuous with an edge of at least one of said projection receiving holes.
Claim 3
Dependent Claim
25 words
An electrical contact as claimed in claimed 1, characterized in that the wire-connection section is a part of the bottom plate and has a slot.
Claim 4
Dependent Claim
29 words
An electrical contact as claimed in claim 1, characterized in that wire holding members are bent inwardly from said side plates across said bottom plate leaving a gap therebetween.
Claim 5
Dependent Claim
21 words
An electrical contact as claimed in claim 1, characterized in that said contact section includes resilient legs having staggered stepped portions.
Claim 6
Dependent Claim
160 words
An electrical contact comprising a holding section formed of opposing side plates bent from a bottom plate, a contact section extending outwardly from said holding section for electrical connection with a circuit board, a wire-connection section between said side plates for electrical connection to an insulated electrical wire and projections at the sides of said wire-connection section disposed in projection-receiving holes in said side plates, characterized in that at least one of said side plates has thermal insulation means interposed between said projections and said side plates for insulating said projections from heat conducted along the contact section and holding section when the contact section is soldered to the circuit board and thereby prevent the melting or softening of the insulation of the electrical wire in the wire-connection section, and wherein said thermal insulation means comprises an insulating gap formed by said at least one projection-receiving hole and a thermal-insulation hole, whereby thermal conductivity is impeded across said insulating gap.
Claim 7
Dependent Claim
160 words
An electrical contact comprising a holding section formed of opposing side plates bent from a bottom plate, a contact section extending outwardly from said holding section for electrical connection with a circuit board, a wire-connection section between said side plates for electrical connection to an insulated electrical wire and projections at the sides of said wire-connection section disposed in projection-receiving holes in said side plates, characterized in that at least one of said side plates has thermal insulation means interposed between said projections and said side plates for insulating said projections from heat conducted along the contact section and holding section when the contact section is soldered to the circuit board and thereby prevent the melting or softening of the insulation of the electrical wire in the wire-connection section, and wherein said thermal insulation means comprises an insulating gap formed by said at least one projection-receiving hole and a thermal-insulation hole, whereby thermal conductivity is impeded across said insulating gap.
