Cable connector having multiple, mutually independent contact arms
View Patent ↗A cable connector is provided including an insulative housing having an insertion opening through which a flat flexible cable may be inserted. An actuator is movably mounted on the housing and configured to be moved from a first position at which the flat flexible cable may be inserted and a second position at which the contact pads of the flat flexible cable are operatively engaged by terminals of the connector. A plurality of conductive terminals are mounted in the housing. Each terminal is configured to be electrically connected to a contact pad of the flat flexible cable. Each terminal includes a base portion disposed at a rear end of the terminal and extending in the vertical direction, an actuator holding arm portion, a front resilient contact arm portion, and a rear resilient contact arm portion. The contact arm portions engage the contact pads in a mutually independent way. The actuator holding arm portion and each contact arm portion have a proximal end thereof secured to the base portion and a contact portion at a free end of thereof.
1. A cable connector, comprising:
an insulative housing, the housing including an insertion opening through which a flat flexible cable may be inserted;
an actuator, the actuator being movably mounted on the housing and configured to be moved from a first position, at which the flat flexible cable may be inserted, and a second position, at which contact pads of the flat flexible cable are operatively engaged by terminals of the connector; and
a plurality of conductive terminals, each terminal being mounted in the housing and configured to be electrically connected to a contact pad of the flat flexible cable, each terminal including a base portion, the base portion disposed at a rear end of the terminal and extending in the vertical direction, an actuator holding arm portion, which engages the actuator to facilitate movement of the actuator between the first and second positions, a front resilient contact arm portion, and a rear resilient contact arm portion, the contact arm portions engage the contact pads in a mutually independent way to maintain secure contact between the contact arm portions and the contact pads;
wherein:
the actuator holding arm portion and each contact arm portion have a proximal end thereof secured to the base portion and a contact portion at a free end of thereof configured to engage the contact pads; and
the first contact arm portion is secured to the base portion below the second contact arm portion.
2. The cable connector according to claim 1 , wherein the actuator is rotatably mounted on the housing for rotational movement between the first and second positions.
3. The cable connector according to claim 2 , wherein the actuator holding arm portion engages a shaft portion of the actuator to facilitate the rotation of the actuator.
4. The cable connector according to claim 3 , wherein the actuator includes a cable pressing surface, the cable pressing surface being opposed to the contact arm portions when the actuator is in the second position.
5. The cable connector according to claim 4 , wherein the contact arm portions are disposed at mutually different positions with respect to an insertion direction of the flat flexible cable.
6. The cable connector according to claim 1 , wherein the contact arm portions are disposed at mutually different positions with respect to an insertion direction of the flat flexible cable.
7. The cable connector according to claim 1 , wherein the actuator includes a cable pressing surface, the cable pressing surface being opposed to the contact arm portions when the actuator is in the second position.
8. The cable connector according to claim 1 , wherein each terminal includes both the actuator holding arm portion for engaging the actuator and the plurality of distinct, resilient, cantilevered, contact arm portions configured to be electrically connected to one of the contact pads.
