Coupling device of charging connector assembly for electric car
First Claim
1. A coupling device of a charging connector assembly for an electric car, wherein a car connector and a charger connector are interconnected to charge a battery in the electric car, comprising:
- a body having a barrel portion and a grip;
an operation lever pivotably connected to said grip and biased by an elastic member toward a direction moving away from said grip;
means for locking said operation lever at a closing position near said grip;
gear means mounted on a proximal end of said barrel portion and engaging with an end of said operation lever;
a front cover mounted on a distal end of said barrel portion for accommodating said charger connector; and
coupling means mounted on said barrel portion movably along the longitudinal direction of said barrel portion and having an end coupled to said gear means and the other end coupled to either one of both said connectors.

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.
