Claim 3

Dependent Claim 26 words

The receptacle of claim 1 characterized in that the second resilient contact portions comprise cantilever spring portions which upstand above the flat flexible cable receiving surface.

Claim 4

Dependent Claim 160 words

An electrical connector for electrically interconnecting conductors of flat flexible cable to a plurality of second conductors, the connector including an insulative housing having a terminal receiving platform with a plurality of terminals aligned side-by-side along the platform for contact with the conductors of the flat flexible cable, the connector being characterized in that: the terminal receiving platform of the insulative housing is profiled for receiving the conductors of the flat flexible cable towards a surface of the platform, and includes side-by-side grooves for receiving the terminals, the terminals each having a cantilever beam portion which projects above a surface of the platform for interconnection to respective facing conductors of the flat flexible cable; and in that the surface of the platform includes sidewalls upstanding therefrom and a moving means which includes an insulating block which is profiled to engageably fit between the sidewalls thereby holding the flat flexible cable in a fixed registration relative to the cantilever beam portions.

Claim 5

Dependent Claim 160 words

An electrical connector for electrically interconnecting conductors of flat flexible cable to a plurality of second conductors, the connector including an insulative housing having a terminal receiving platform with a plurality of terminals aligned side-by-side along the platform for contact with the conductors of the flat flexible cable, the connector being characterized in that: the terminal receiving platform of the insulative housing is profiled for receiving the conductors of the flat flexible cable towards a surface of the platform, and includes side-by-side grooves for receiving the terminals, the terminals each having a cantilever beam portion which projects above a surface of the platform for interconnection to respective facing conductors of the flat flexible cable; and in that the surface of the platform includes sidewalls upstanding therefrom and a moving means which includes an insulating block which is profiled to engageably fit between the sidewalls thereby holding the flat flexible cable in a fixed registration relative to the cantilever beam portions.

Claim 6

Dependent Claim 26 words

The electrical connector of claim 3 characterized in that the insulating block and sidewalls include complementary ratchet teeth for progressive locking arrangement in successive lowered positions.

Claim 7

Dependent Claim 109 words

An electrical connector having an insulative housing and a plurality of electrical terminals therein, the electrical terminals having resilient contact portions and conductor connecting portions, and an insulating block which is moveable towards the conductor connecting portions of the terminals to move conductors into electrical engagement therewith, the connector being characterized in that: the housing includes a terminal support platform which houses the terminals in side by side arrangement therealong, the housing further including two sidewalls which upstand from the platform and flank the support platform, the sidewalls and the insulating block each including complementary ratchet teeth for progressive locking arrangement of the conductors with the conductor connecting portions.

Claim 8

Dependent Claim 109 words

An electrical connector having an insulative housing and a plurality of electrical terminals therein, the electrical terminals having resilient contact portions and conductor connecting portions, and an insulating block which is moveable towards the conductor connecting portions of the terminals to move conductors into electrical engagement therewith, the connector being characterized in that: the housing includes a terminal support platform which houses the terminals in side by side arrangement therealong, the housing further including two sidewalls which upstand from the platform and flank the support platform, the sidewalls and the insulating block each including complementary ratchet teeth for progressive locking arrangement of the conductors with the conductor connecting portions.

Claim 9

Dependent Claim 43 words

The electrical connector of claim 5 characterized in that the housing is profiled to receive flat flexible cable conductors, the housing including a platform having a cable receiving surface having a plurality of grooves which receive the conductor connecting portions of the terminals.

Claim 10

Dependent Claim 34 words

The electrical connector of claim 6 characterized in that the conductor connecting portions are defined by cantilever beam portions, an upper contact area of which projects above the surface of the cable receiving surface.
