Electric connector

Claim 2

A low insertion force electrical connector adapted to connect a conductor of a first flat flexible circuit member having at least one conductor to another circuit member, said connector including, a housing with a forward conductor receiving opening and a bottom wall, a terminal mounted in the housing with a base connected to said another circuit member and a flexible arm, wherein said bottom wall and said flexible arm defining a mating region therebetween communicating with said conductor receiving opening, said flexible arm, adapted to be placed in either a preloaded or non-preloaded position, having a contact point on a side of said flexible arm adapted to be positioned out of electrical contact with said conductor in said preloaded position, allowing said conductor to be inserted in said mating region, and said contact point adapted to electrically mate with said conductor in said non-preloaded position after said cable with said conductor is received within the mating region, an actuator slidingly received within said mating region between said bottom wall and said flexible arm and having a front portion, the improvement comprising: said terminal flexible arm having a cam surface separate from said contact point and on the same side of the flexible arm as the contact point, and said actuator front portion having a cam follower adapted to contact an extended section of said cam surface and force said contact point away from said conductor in said preloaded position and, as the actuator is further inserted into the mating region, said cam follower sliding off said extended section onto a non-extended section of said cam surface in said non-preloaded position allowing said flexible arm to force said contact point toward the conductor, establishing an electrical connection therebetween.

Claim 3

An electrical connector according to claim 1, wherein said non-extended section of the cam surface is adjacent the extended section of the cam surface with a gradual transition section extending longitudinally therebetween.

Claim 4

An electrical connector according to claim 1, wherein said contact point is followed first by a non extended section, next by an extended section and finally by another non-extended section with a curved transition section extending between said extended and said non-extended sections.

Claim 5

An electrical connector according to claim 1, wherein said actuator has a flat surface upon which said flat flexible cable can lie while said actuator moves from said preloaded to said non-preloaded positions.

Claim 6

An electrical connector according to claim 4 wherein said flat surface has an inclined surface with increasing depth as the inclined surface approaches the front portion of the actuator.

Claim 7

A low insertion force electrical connector adapted to connect a conductor of a first flat flexible circuit member having at least one conductor to another circuit member, said connector including, a housing with a forward conductor receiving opening and a bottom wall, a terminal mounted in the housing with a base connected to said another circuit member and a flexible arm, wherein said bottom wall and said flexible arm defining a mating region therebetween communicating with said conductor receiving opening, said flexible arm, adapted to be placed in either a preloaded or non-preloaded position, having a contact point adapted to be positioned out of electrical contact with said conductor in said preloaded position, allowing said conductor to be inserted in said mating region, and said contact point adapted to electrically mate with said conductor in said non-preloaded position after said cable with said conductor is received within the mating region, an actuator slidingly received within said mating region between said bottom wall and said flexible arm and having a front portion, the improvement comprising: said terminal flexible arm having cam surface; said actuator having a flat surface upon which said flat flexible circuit member can lie while said actuator moves from said preloaded to said non-preloaded positions said flat surface being inclined with increasing depth as the flat surface approaches the front portion of the actuator, and said actuator front portion having a cam follower adapted to contact an extended section of said cam surface and force said contact point away from said conductor in said preloaded position and, as the actuator is further inserted into the mating region, said cam follower sliding off said extended section onto a non-extended section of said cam surface in said non-preloaded position allowing said flexible arm to force said contact point toward the conductor, establishing an electrical connection therebetween.

Claim 8

A low insertion force electrical connector adapted to connect a conductor of a first flat flexible circuit member having at least one conductor to another circuit member, said connector including, a housing with a forward conductor receiving opening and a bottom wall, a terminal mounted in the housing with a base connected to said another circuit member and a flexible arm, wherein said bottom wall and said flexible arm defining a mating region therebetween communicating with said conductor receiving opening, said flexible arm, adapted to be placed in either a preloaded or non-preloaded position, having a contact point adapted to be positioned out of electrical contact with said conductor in said preloaded position, allowing said conductor to be inserted in said mating region, and said contact point adapted to electrically mate with said conductor in said non-preloaded position after said cable with said conductor is received within the mating region, an actuator slidingly received within said mating region between said bottom wall and said flexible arm and having a front portion, the improvement comprising: said terminal flexible arm having cam surface; said actuator having a flat surface upon which said flat flexible circuit member can lie while said actuator moves from said preloaded to said non-preloaded positions said flat surface being inclined with increasing depth as the flat surface approaches the front portion of the actuator, and said actuator front portion having a cam follower adapted to contact an extended section of said cam surface and force said contact point away from said conductor in said preloaded position and, as the actuator is further inserted into the mating region, said cam follower sliding off said extended section onto a non-extended section of said cam surface in said non-preloaded position allowing said flexible arm to force said contact point toward the conductor, establishing an electrical connection therebetween.
