Abstract
Abstract In a press-in type terminal member for a single core cable, a temporary holding space is formed between contact arms and above a conductor press-in slot, to temporarily hold the cable before press-in operation. The terminal member may have an outward projection which forms another temporary holding space in cooperation with an adjacent terminal member, to hold another cable for a second row of terminals which is staggered from the first row of terminals.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
345 words
An electric contact terminal member for accomodating therein a single core cable having exterior insulation, said terminal member comprising: a first metal plate having formed therefrom a first pair of contact arms defining therebetween a first slot having an open outer end adjacent outer ends of said first pair of contact arms; said first slot including an inlet portion extending inwardly from said open outer end of said first slot, said inlet portion being dimensioned to receive and grasp a single core cable including insulation thereof without damage to the insulation; said first slot including a press-in portion extending inwardly from said inlet portion, said press-in portion being dimensioned to, upon the cable being pressed thereinto, receive the core of the cable, while the cable insulation is broken by facing edges of said first pair of contact arms; said first pair of arms having adjacent said outer ends thereof integral projection means extending into said inlet portion of said first slot for aiding in grasping the cable; said inlet portion of said first slot and said projection means forming temporary holding means for enabling accurate positioning of the cable before the cable is pressed into said press-in portion; a second metal plate having formed therefrom a second pair of contact arms defining therebetween a second slot having an open outer end adjacent outer ends of said second pair of contact arms; said second metal plate being positioned adjacent said first metal plate, with said second pair of contact arms parallel to said first pair of contact arms, and with said second slot parallel to said first slot; said second slot being dimensioned to, upon the cable being pressed thereinto, receive the core of the cable, while the cable insulation is broken by facing edges of said second pair of contact arms; and said outer ends of said second pair of contact arms being outwardly pointed to facilitate breaking of the cable insulation upon the cable being pressed from said temporary holding means into said press-in portion of said first slot and into said second slot.
Claim 2
Dependent Claim
345 words
An electric contact terminal member for accomodating therein a single core cable having exterior insulation, said terminal member comprising: a first metal plate having formed therefrom a first pair of contact arms defining therebetween a first slot having an open outer end adjacent outer ends of said first pair of contact arms; said first slot including an inlet portion extending inwardly from said open outer end of said first slot, said inlet portion being dimensioned to receive and grasp a single core cable including insulation thereof without damage to the insulation; said first slot including a press-in portion extending inwardly from said inlet portion, said press-in portion being dimensioned to, upon the cable being pressed thereinto, receive the core of the cable, while the cable insulation is broken by facing edges of said first pair of contact arms; said first pair of arms having adjacent said outer ends thereof integral projection means extending into said inlet portion of said first slot for aiding in grasping the cable; said inlet portion of said first slot and said projection means forming temporary holding means for enabling accurate positioning of the cable before the cable is pressed into said press-in portion; a second metal plate having formed therefrom a second pair of contact arms defining therebetween a second slot having an open outer end adjacent outer ends of said second pair of contact arms; said second metal plate being positioned adjacent said first metal plate, with said second pair of contact arms parallel to said first pair of contact arms, and with said second slot parallel to said first slot; said second slot being dimensioned to, upon the cable being pressed thereinto, receive the core of the cable, while the cable insulation is broken by facing edges of said second pair of contact arms; and said outer ends of said second pair of contact arms being outwardly pointed to facilitate breaking of the cable insulation upon the cable being pressed from said temporary holding means into said press-in portion of said first slot and into said second slot.
Claim 3
Dependent Claim
22 words
A terminal member as claimed in claim 1, wherein said first and second metal plates are in abutting contact with each other.
Claim 4
Dependent Claim
25 words
A terminal member as claimed in claims 1 or 2, wherein said first and second metal plates are integrally formed of a single metal element.
Claim 5
Dependent Claim
34 words
A terminal member as claimed in claim 1, wherein said first pair of arms have adjacent said outer ends thereof outwardly extending projections for cooperation with adjacent separate terminal members for holding other cables.
