Abstract
A coupling device interconnects a car connector BC and a charger connector SC positively by a small force to charge a battery in an electric car. After incompletely coupling, when an operation lever 8 together with a grip 32 are grasped, a sector gear 16 is turned to an anticlockwise direction and a pinion 15 is rotated to the anticlockwise direction through an intermediate gear 17. Thus a coupling plate 10 is moved from an advanced position to a retracted position through engagement of the pinion 15 and a rack 13. Distal ends of the coupling plates 10 are closed during a former movement of the plates so that windows 21 in the plates receive projections 22 on a connector housing of a car connector BC. A connector housing 2 of a charger connector SC together with a body 3 are drawn into the housing 1 during a latter movement of the plates, thereby completely interconnect both connectors BC and SC. When the lever 8 returns to an opening position, the coupling plate 10 is backed from the retracted position to return the housing 2 together with the body 3 and detach the housing 1. When the body 3 is pulled, both connectors BC and SC are separated.
