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 a proximal end of said barrel portion 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;
a link mechanism 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 link mechanism 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 under a small force to charge a battery in an electric car. After bringing housings 1 and 2 of both connectors BC and SC, when an operation lever 8 together with a grip 32 are grasped, an engaging projection 229 pushes a rear end of a coupling groove 228 so that a coupling plate 10 is moved from an advanced position to a retracted position. During a former movement of the plates 10, a projection 232 rids on an inner side from a rear edge of an escape groove 233 so that distal ends of the coupling plates 10 are closed. Consequently, windows 231 in the plates receive projections 209 on the housing of the car connector BC. The housing 2 of the charger connector SC together with a body 3 are drawn into the housing 1 during a latter movement of the plates, thereby completely interconnecting 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 the distal end of the coupling plates 10 are widened to detach the housing 1. When the body 3 is pulled, both connectors BC and SC are separated.
