Abstract
Abstract The feeder connector consists of feeding-side and receiving-side connectors. The feeding-side connector includes a casing consisting of split-type cases fastened to each other, a connector body slidably installed in a front half section of the casing, and a handle movably mounted in a rear half section of the casing such that it advances through rotation of a lever to push the connector body against the receiving-side connector, the handle also serving as lead wires-passing tube. The lever includes a first locking means for locking the connector body in an engaged state with a mating connector body of the receiving-side connector, a second locking means operated through energizing an electro-magnetic coil, and a means for releasing the lever from the locking by the first locking means after the locking by the second locking means is released by deenergizing. The feeder connector prevents the feeding-side and receiving-side connectors from detachment during feeding in charging an electric vehicle and has a simple structure suitable for multi-polarization.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
148 words
A feeder connector including a feeding-side connector provided on a side of a feeder apparatus and a receiving-side connector provided on a body of a vehicle or the like, said feeding-side connector comprising: a casing; a connector body slidably installed in a front half section inside said casing and accommodating a plurality of terminals; a hollow-shaped handle that allows lead wires connected to said plurality of terminals to pass therethrough; a lever at an intermediate portion thereof rotatably supported inside said casing and including an operating portion extending outside said casing, said lever, when rotated, causing said connector body to move forwardly into engagement with said receiving-side connector; and an electro-magnetic locking means provided at a position offset from a fitting axis of said connector body for restricting the rotation of said lever such that said connector body and said receiving-side connector are maintained engaged with each other.
Claim 2
Dependent Claim
148 words
A feeder connector including a feeding-side connector provided on a side of a feeder apparatus and a receiving-side connector provided on a body of a vehicle or the like, said feeding-side connector comprising: a casing; a connector body slidably installed in a front half section inside said casing and accommodating a plurality of terminals; a hollow-shaped handle that allows lead wires connected to said plurality of terminals to pass therethrough; a lever at an intermediate portion thereof rotatably supported inside said casing and including an operating portion extending outside said casing, said lever, when rotated, causing said connector body to move forwardly into engagement with said receiving-side connector; and an electro-magnetic locking means provided at a position offset from a fitting axis of said connector body for restricting the rotation of said lever such that said connector body and said receiving-side connector are maintained engaged with each other.
Claim 3
Dependent Claim
43 words
A feeder connector according to claim 1, wherein said electro-magnetic locking means comprises an electro-magnetic coil energized on sensing a current flow such that said lever is locked against rotation to maintain said connector body and said receiving-side connector engaged with each other.
Claim 4
Dependent Claim
33 words
A feeder connector according to claim 2, wherein said electro-magnetic coil is provided with a plunger axially movable, on energizing said magnetic coil, into engagement in a corresponding bore formed on said lever.
Claim 5
Dependent Claim
62 words
A feeder connector according to claim 1, wherein said hollow-shaped handle is mounted in a rear half section inside said casing and coaxially slidable with said connector body, and wherein said lever is at a front working portion thereof pivotally attached to said handle so that said connector body is brought into engagement with said receiving-side connector through advancement of the handle.
Claim 6
Dependent Claim
26 words
A feeder connector according to claim 4, wherein said handle is formed as a single unit and moves as a whole when said lever is rotated.
Claim 7
Dependent Claim
54 words
A feeder connector according to claim 1, wherein said feeding-side connector further comprises a second locking means for locking said lever and a release means for releasing said lever from said second locking means after the locking of said lever by said electro-magnetic locking means is released through deenergizing of the magnetic locking means.
Claim 8
Dependent Claim
42 words
A feeder connector according to claim 6, wherein said second locking means and said release means comprise a single release lever rotatably attached at an intermediate portion thereof to said casing and engageable at a front working portion thereof with said lever.
Claim 9
Dependent Claim
42 words
A feeder connector according to claim 4, wherein said front half section and said rear half section inside said casing are divided by a partition wall with an opening through which said handle passes to come into contact with said connector body.
Claim 10
Dependent Claim
26 words
A feeder connector according to claim 8, wherein said feeding-side connector further comprises a spring means that normally urges said connector body towards said partition wall.
Claim 11
Dependent Claim
43 words
A feeder connector according to claim 5, wherein said handle has a rear half portion extended outside said casing and bent downwardly to form a grip portion, and wherein said operating portion of said lever may be grasped together with said grip portion.
Claim 12
Dependent Claim
28 words
A feeder connector according to claim 7, wherein said feeding-side connector further comprises a means engageable with said receiving-side connector to lock said feeding-side and receiving-side connectors together.
Claim 13
Dependent Claim
61 words
A feeder connector according to claim 11, wherein said connectors-locking means comprises a spring-urged locking arm rotatably supported to said casing, and wherein said working portion of said release lever is located between said lever and said connectors-locking means such that stepwise operation of said release lever unlocks said lever and then unlocks said feeding-side and receiving-side connectors from each other.
