Lock detecting terminals are disposed on one of connector housings that are engageable with each other, and a short circuit terminal is disposed on the other connector housing, the short circuit terminal serving to short-circuit the lock detecting terminals upon engagement of both housings. The lock detecting terminals are arranged so as to extend along an inner wall surface of the housing in such a manner that the distal ends thereof are not contact with the edge portion of the engagement opening of the housing. As a result of this construction, the lock detecting terminals will no longer be deformed while caught by the edge portion of the housing even when the housing is being engaged with the housing misaligned. Furthermore, the one connector has the short circuit electrode exposed to the outside and has a cover movable between a protecting position and an opening position, the protecting position being such a position as to allow the cover to cover the short circuit electrode, the opening position being such a position as to allow the cover to expose the short circuit electrode.

An electrical connector assembly used for charging an electric vehicle includes a power source side connector and a vehicle side connector. The power source side connector is detachably connected to the vehicle side connector mounted on the body of an electric vehicle. A locking device disposed in the power source side connector is turned to a locking state with an ignition key of the electric vehicle so that the connectors are locked in the mating engagement. Since the power source side connector cannot be disconnected from the vehicle side connector, charging can be prevented from being inadvertently interrupted. The charging can be initiated only when the connectors are locked in the mating engagement. Alternatively, the locking device can be used to lock a switch of a charging circuit in a closed position which allows charging to take place.

A cover 20 is attached to connector body 10, and has a connecting and supporting member 30 engageable with a receiving member 16. Once engaged the member 30 cannot be removed. The connecting and supporting member 30 can be released only by breaking a breakable member 32. Consequently the connection of the cover 20 with the connector body 10 is maintained with certainty. In a preferred embodiment a part of the breakable member 31 is retained after breaking, this giving evidence that the cover has been removed.

In a connector of male and female interlocking terminals, a lever is provided on a first connector in a freely pivoting manner. Guide pins provided on a second connector are inserted to guide channels formed in the first connector. A stopper block is provided on the top wall of the first connector. A spring is connected between the back side of the lever and the back side on the top wall of the first connector. The lever is pulled by the spring against the stopper block and is held at a disengaging position in which guide grooves formed inside the lever and the guide channels are aligned to form an inlet for the guide pins. Since the lever is automatically returned to the disengaging position by the spring even if the lever is accidentally turned, it is not necessary to re-rotate the lever to the disengaging position, making connecting operation smoothly.

A contact face 16 of a rib 15 is arranged to be inclined downwards with respect to the fitting direction of connector housings 10,20. Detecting terminal fittings 14 make contact with the contact face 16 and are resiliently bent in a predetermined manner. If the rib 15 should be bent away from the detecting terminal fittings 14, the detecting terminal fittings 14 follow due to their inherent resilience and thereby maintain contact with the contact face 16.

A plasma shutter forming apparatus for forming a plasma shutter used in a system configured to generate and accelerate radiations by irradiating a target with a laser pulse and generating a high-density plasma for blocking the laser pulse which is returned as a feedback light to upstream of the system without being absorbed by the high-density plasma, including a plasma shutter generating target, and a plasma shutter triggering laser irradiator, wherein the laser pulse from the plasma shutter triggering laser irradiator is directed to the plasma shutter generating target to generate the high-density plasma and form the plasma shutter, thereby blocking the laser pulse which is returned as the feedback light. Optics are prevented from becoming damaged by feedback light reflecting when generating the high-density plasma in a laser-driven radiation generating system and returning back to the upstream of the laser system.

A board-mounted-type connector 1 includes a housing body 3, metal terminals 2 mounted in the housing body 3, and a retainer 4 mounted on the lower side of the housing body 3 to hold the metal terminal 2 against withdrawal. The metal terminal 2 has connecting ports 5A and 5B formed respectively at its upper end lower ends. The board-mounted-type connector 1 is mounted on a board 12, and in this condition each mating metal terminal 7 can be connected to the associated metal terminal 2 through a terminal-loosely-fitting hole 30, formed in the board 12, from that side of the board 12 facing away from the board-mounted-connector 1.

An opening which leads inside a surface-moutable switch is sealed by a tape seal, a good seal being maintained even when heat is applied to the switch. A switch body has a top surface and an inner space in which an electrical contact is provided. A switch knob operating the electrical contact provided inside the switch is accessed through the opening. The tape seal seals the opening with an adhesive applied between the tape seal and a top surface of a switch body. A portion of the tape seal directly above the opening is drawn into the opening by a negative pressure in the opening. The surface-mountable switch is manufactured by placing the switch body applied with the tape seal in a vacuum chamber so as to evacuate air surrounding the switch body. The seal for the opening is temporarily broken by an air pressure inside the opening, and the pressure inside the opening becomes a negative pressure with respect to the atmospheric pressure. The portion of the tape seal directly above the opening is drawn into the opening. The switch body applied with the tape seal may be simply heated so that the air inside the opening is expanded. The expanded air is abruptly discharged through an air vent opening formed between the tape seal and the switch body. A negative pressure is generated in the opening to draw the tape seal into the opening, and the opening is hermetically sealed.

A battery terminal for a terminal post of a battery includes a terminal body formed by a single plate. The terminal body has top and bottom terminal members each continuous to top and bottom tightening members. The top and bottom tightening members are provided with tapered outer surfaces. A tightening tool having upper stage tapered surfaces and lower stage tapered surfaces is place above the tightening members. When the tightening tool is pressed against the tightening members, the upper stage tapered surfaces and the lower stage tapered surfaces press said first and second tapered outer surface to compress said top and bottom terminal members to firmly hold the terminal post.

An electrical connector includes a connector housing having a drain hole. A vacuum pump is connected to the drain hole through a suction pipe. The suction pipe is connected to a water trap. A control unit controls the vacuum pump on the basis of the state of a mode selecting switch and a reed switch detecting the state of a lid for closing and opening an open end of the connector housing. In mode A, the vacuum pump is actuated to aspirate water from in the connector housing with air while the lid is open. In mode B, the vacuum pump is actuated both when the lid is opened and when the lid is closed.
