A C-shaped fixed core is provided at a power receiving portion, and a secondary coil is wound on a vertical portion of the fixed core. A moving core is vertically movable in sliding contact with distal end surfaces of horizontal portions of the fixed core. A primary coil, having an air core portion, is provided at a charging coupler. When the charging coupler is attached to the power receiving portion, the moving core is moved downward to extend through the air core portion of the primary coil, and opposite end portions of the moving core are contacted respectively with the horizontal portions of the fixed core. As a result, a magnetic circuit is formed between the primary and secondary coils. The charging coupler is lightweight since it does not have a core.

To prevent increase in stress on a soldered join between a terminal pin and a circuit board in the event of thermal expansion, a support (22) with a larger diameter and a recess (21) with a smaller diameter are formed on a terminal pin (20). An alignment plate (30) is arranged to be movable with respect to a connector housing (11) between a support position in which the support member (22) is a close fit in a position fixing hole (31), and a release position in which the recess (21) is a loose fit. This eliminates the increase in stress on the soldered portion (M) due to differing rates of thermal expansion and contraction of the circuit board (P) and alignment plate (30).

Magnetic coupling device for charging an electric vehicle

Groups of magnets are respectively provided on the joint surfaces of a vehicle-side connector and a power-supply-side connector in such a way that the N and S poles of a plurality of permanent magnets are alternately arranged in a circle. When charging is carried out, the magnetic attraction generated by placing the heteropolar magnets in both groups of magnets opposite to one another is utilized for bringing the vehicle-side connector and the power-supply-side connector into engagement with each other. After the charging, the group of magnets of the power-supply-side connector are turned by one pitch to place the homopolar magnets in both groups of magnets opposite to one another, whereby both connectors are easily separated from each other because of the magnetic repulsive force generated therebetween.

A magnetic coupling device for charging an electric vehicle includes: a primary unit having a primary core and a primary coil wound on the primary core; and a secondary unit having a secondary core and a secondary coil wound on the secondary core, the secondary unit disposed on the electric vehicle and coupled with the primary unit, so that the primary and secondary cores constitute a closed loop-like magnetic circuit; each of the primary and secondary cores having a junction face which contacts with each other under the coupling, wherein the junction faces of the primary and secondary cores have a mutually opposing relationship in which the junction faces intersect with an attaching direction of the primary unit.

To facilitate the charging of an electric automotive vehicle, a primary coil 31 connected with a charging power source is so provided as to project from a wall surface W of a parking space. An electric automotive vehicle E is advanced toward the wall surface W and parked in a position where the primary coil 31 is accommodated in a receptacle 11 provided below a front bumper B of the vehicle E. Then, a pressure switch 40 provided in a shock absorbing material 39 operates to detect the presence of the vehicle E, and the primary coil 31 is excited. A secondary coil 14 is provided above the receptacle 11. A voltage is generated in the secondary coil 14 by action of electromagnetic induction, thereby charging a battery 19.

Connecting system and a connection method

A slidable element is provided for easy positioning in a guide slot when a handle is withdrawn. A handle 40 is inclinably provided on a mount body 35 bearing a movable electrode 31 by a support shaft 45. The support shaft 45 is loosely movable with respect to the mount body 35 by being fixed to the handle 40 and being inserted through oblong holes 42 formed in bearing portions 41 of the mount body 35. In order to withdraw the handle 40, it is necessary to position slidable projections 70 at the bottom ends of linear portions 75 of guide slots 74 while the handle 40 is pulled up. Since the support shaft 45 is movable upward within the oblong holes 42, the handle 40 can singly be pulled up while the movable electrode 31 is still engaged with the fixed electrodes 11a, 11b. During this time, the slidable projections 70 can be positioned and passed through the linear portions 75 of the guide slots 74 with a small force.

Breaker device

A breaker device is provided to prevent an insufficient engagement of electrodes. The device, according to the invention, is excellent in safety because of its construction in which a conductive path is located inside the casing 1 and is allowed to have a compact configuration of particularly low height because a handle 40 can be inclined to its resting position. When the handle 40 is inclined to the resting position while a movable electrode 31 is insufficiently engaged, engaging portions 77 come into contact with receiving portions 75 and a lever action works with the contact positions of the engaging portions 77 and the receiving portions 75 as a fulcrum. As a result, a rotating force applied to an operable portion 40A is translated into a downward acting engaging force applied to the movable electrode 31 via rotation center shafts 45 and a mount body 35. In other words, since the movable electrode 31 is brought into its properly engaged state by inclining the handle 40 to the resting position, the insufficient engagement of the movable electrode 31 can be prevented.

A compact breaker device includes a pair of fixed electrodes 11a, 11b are placed upright at one side of the casing 1, and a fuse 12 is accommodated at the other side thereof. A movable electrode 31 including a pair of fittable terminals 32a, 32b connected with each other is mounted on a mount body 35. By engaging and disengaging the fittable terminals 32a, 32b with and from the fixed electrodes 11a, 11b through the ceiling wall of the casing 1, a breaker switch for connect and disconnect the fixed electrodes 11a, 11b is formed. The fuse 12 is connected in series with the breaker switch. A handle 40 is inclinably mounted on the upper surface of the mount body 35. The handle 40 is firmly held in a standing position and a resting position by a spring member 47 provided between it and the mount body 35. The handle 40 is inclined to the resting position when the breaker device is used, while being held upright when the breaker switch is turned on and off.

A connection system and connection method for easily charging an electric automotive vehicle are provided. A secondary coil 20 connected with a battery 21 is provided at the bottom of a body of an electric automotive vehicle E. On the other hand, a recess A is formed in the ground of a parking lot, and a coil moving device 30 for movably supporting a primary coil 10 is installed in the recess A. Three magnetic sensors 50 are provided on a body 40 of the coil moving device 30. Further, power supply circuits 13a to 13e provided in an external power supply equipment 11 at the back of the parking lot and a main controller 12 supply power to the primary coil 10, magnetic sensors 50 and coil moving device 30 and control them. In order to charge the battery 21, the vehicle E is parked, straddling the recess A, and the secondary coil 20 is excited. Then, the magnetic sensors 50 detect the position of the secondary coil 20, and the main controller 12 drives the coil moving device 30 to guide the primary coil 10 to a position where both coils 10, 20 are to be electromagnetically coupled.

Connection system and connection method for an electric automotive

A connector for a printed circuit board which minimizes the deformation of the positioning member for aligning terminals. The engaging members are located at the outside of guide surfaces formed on the outer surfaces of the housing of the connector. The spacing between the engaging members is longer than if they were located inwardly of the guide walls projecting from the front surface of the housing. Accordingly, the deformation per unit length of the positioning member is small. Such a small deformation of the positioning member minimizes the misalignment of the holes into which the terminals are to enter. Thus, the terminals can be aligned with great accuracy.
