Abstract

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes at least one first electrical contact and an actuator movable between a first position and a second position. The second electrical contact device includes at least one second electrical contact device and an interlock feature to engage the actuator when the actuator is in the first position. The actuator is in the first position when the first electrical contact is in electrical communication with a power source, and the actuator is in the second position when the electrical communication between the first electrical contact and the power source is disconnected. When the actuator is in the first position and the second electrical contact engage the first electrical contact, the interlock feature engages the actuator, thereby securing the first electrical contact device and the second electrical contact device against disconnection.

First claim

What is claimed is:

1. An electrical connector assembly comprising:
a first electrical contact device including at least one first electrical contact and an actuator movable between a first position and a second position, the actuator being in the first position while the at least one first electrical contact is in electrical communication with a power source, the actuator being in the second position while the electrical communication between the at least one first electrical contact and the power source is disconnected; and
a second electrical contact device including at least one second electrical contact and a connector to engage the actuator when the actuator is in the first position and the at least one second electrical contact engages the at least one first electrical contact, the engagement of the connector and the actuator secures the first electrical contact device and the second electrical contact device against disconnection,
wherein the actuator is a first latch, wherein one of the first electrical contact device and the second electrical contact device includes a second latch engaging a second connector on the other of the first electrical contact device and the second electrical contact device, and
further comprising a first solenoid and a second solenoid, the first solenoid preventing the first latch from disengaging the first connector when the first solenoid is in a first position, the first solenoid permitting the first latch to disengage the first connector when the first solenoid is in a second position, the second solenoid preventing the second latch from disengaging the second connector when the second solenoid is in a first position, the second solenoid permitting the second latch to disengage the second connector when the second solenoid is in a second position.

2. The electrical connector assembly of claim 1 , wherein the at least one first electrical contact includes a plurality of electrical contacts oriented in a first plane that is at an oblique angle to a longitudinal direction of the actuator.

3. The electrical connector assembly of claim 1 , wherein the at least one first electrical contact includes a plurality of electrical contacts extending parallel to a connection direction, the actuator being movable between the first position and the second position in a direction that is transverse to the connection direction.

4. The electrical connector assembly of claim 1 , wherein the first latch locks the first electrical contact device to the second electrical contact device when fully connected.

5. The electrical connector assembly of claim 1 , further comprising an indicator signifying an electrical state of the electrical connector assembly.

6. The electrical connector assembly of claim 1 , wherein when the actuator is in the first position, the at least one first electrical contact is inhibited from moving in a translational direction to engage or disengage the at least one second electrical contact, and when the actuator is in the second position, the at least one first electrical contact is permitted to move in the translational direction to engage or disengage the at least one second electrical contact.

7. The electrical connector assembly of claim 1 , wherein the actuator receives an input power from the power source by an auxiliary circuit.

8. The electrical connector assembly of claim 1 , wherein the actuator is driven between the first position and the second position by an electromagnet.
