Conductor connection terminal and method of connection

Claim 2

A connection terminal having a connection portion for gripping two sides of a conductor accommodated in a groove disposed between groove-forming partitions of a terminal holder and bent back at the end of the terminal holder so as to connect to the conductor, said connection portion provided with a fork comprised of two prong portions facing each other across a slot of a size not substantially greater than the effective thickness of the bent back conductor so as to grip the two sides of the conductor bent back in the groove at the end of the terminal holder, and said fork having substantially flat prong portions of a thickness not substantially greater than the width of the conductor, and thick portions projecting laterally out from side surfaces of the flat prongs and having a thickness for insertion in the groove of the terminal holder and closely fitting between the partitions to laterally stabilize the connection portion position on the terminal holder.

Claim 3

A connection terminal as set forth in claim 1, wherein front ends of the prongs facing each other across the slot comprising the fork are formed with oppositely inclined surfaces across the slot so as to facilitate insertion over the bent back conductor.

Claim 4

A connection terminal as set forth in claim 2, wherein front ends of the prongs facing each other across the slot comprising the fork are formed with the opposed projections so as to press against the conductor.

Claim 5

A connection terminal as set forth in claim 3, wherein the interval between the prongs facing each other across the slot comprising the fork are spaced slightly narrower than the effective thickness of the conductor bent back at the terminal holder.

Claim 6

A connection terminal as set forth in claim 4, wherein the prongs facing each other across the slot comprising the fork have resiliency in a direction facing each other across the slot.

Claim 7

A connection terminal as set forth in claim 1, wherein a portion for connection to a wire is provided at the side of the prongs opposite to the slot.

Claim 8

A connection terminal as set forth in claim 1, wherein the conductor is at least one conductor of a flat cable, comprised of a plurality of conductors arranged at predetermined intervals and covered with an insulator, from which part of the insulating covering has been removed to expose the same.

Claim 9

A connection terminal as set forth in claim 7, wherein the opposed prongs are formed with surfaces divergently inclined toward the frontmost end for gripping the conductor.

Claim 10

A connection terminal as set forth in any one of claims 1 to 8, wherein the connection terminal is formed by bending a single sheet of conductive metal and has a thickness when bent which is not substantially greater than the thickness of the conductor.

Claim 11

A connection terminal as set forth in claim 9, wherein projecting portions comprising the thick portions are formed on the single sheet of conductive metal.

Claim 12

A connection terminal as set forth in claim 1, wherein the effective lateral thickness of the thick portions of the prongs of the connection terminal is a thickness not substantially greater than the lateral width of the groove of the terminal holder.

Claim 13

A connection terminal having a connection portion for gripping two sides of a conductor accommodated in a groove disposed between groove-forming partitions of a terminal holder and bent back at the end of the terminal holder so as to connect to the conductor, the connection portion comprising a fork having two resilient prongs facing each other across a slot of a size not substantially greater than the effective thickness of the bent back conductor so as to grip the two sides of the conductor bent back in the groove at the end of the terminal holder, the lateral thickness of the prongs being formed not substantially greater than the lateral width of the conductor, thick portions projecting laterally outward from side surfaces of the prongs and defining a thickness for insertion in the grooves of the terminal holder and closely fitting between the partitions to laterally stabilize the position of the connection portion on the terminal holder, the prongs each having wedge shaped surfaces to facilitate insertion of said fork on said bent back conductor, said wedge shaped surfaces terminating in projections disposed at oppositely spaced locations across the slot and the interval between the projections being set smaller than the effective thickness of the conductor to be gripped, and the conductor being effectively connected by the resiliency of the facing prongs.

Claim 14

A connection terminal having a connection portion for gripping two sides of a conductor accommodated in a groove disposed between groove-forming partitions of a terminal holder and bent back at the end of the terminal holder so as to connect to the conductor, the connection portion comprising a fork having two resilient prongs facing each other across a slot of a size not substantially greater than the effective thickness of the bent back conductor so as to grip the two sides of the conductor bent back in the groove at the end of the terminal holder, the lateral thickness of the prongs being formed not substantially greater than the lateral width of the conductor, thick portions projecting laterally outward from side surfaces of the prongs and defining a thickness for insertion in the grooves of the terminal holder and closely fitting between the partitions to laterally stabilize the position of the connection portion on the terminal holder, the prongs each having wedge shaped surfaces to facilitate insertion of said fork on said bent back conductor, said wedge shaped surfaces terminating in projections disposed at oppositely spaced locations across the slot and the interval between the projections being set smaller than the effective thickness of the conductor to be gripped, and the conductor being effectively connected by the resiliency of the facing prongs.
