Abstract: The present invention is directed toward a protective cap with grease fitting that is designed and configured to cover an electrical plug such that the prongs of the plug do not corrode when the plug is not in use. The protective cap may include a housing with an exterior wall and an interior wall, a plurality of grooves within the housing, and a self-lubricating plastic that encases the grooves within the housing.

Abstract: A moving plate moves from a protection position for protecting a tip part of a male tab to a connection position in a receptacle according to a connecting operation of a female housing. A male housing includes a male housing lock, and the female housing includes a female housing lock. The moving plate includes a plate male lock for locking the male housing lock at the protection position to restrict a movement to the connection position, and a plate female lock for locking the female housing-side locking portion to restrict separation of the female housing when locking of the male housing lock and the plate male lock is maintained.

Abstract: Systems and methods are disclosed for automatically or remotely rendering a solar array safe during an emergency or maintenance. A watchdog unit is disclosed for monitoring a signal from a central controller. If the signal is lost, interrupted, or becomes irregular, or if a shutdown signal is received, then the watchdog unit can shutdown one or more solar modules. Shutting down a solar module can mean disconnecting it from a power bus of the solar array or lowering the solar module voltage to a safe level.

Abstract: There is disclosed a power connection apparatus which can secure connection between a power socket and a power plug with a simple constitution and which can simplify the connecting operation properties thereof. A handle rotatably attached to the power plug having terminals includes engaging claw disengageably engaged with engagement portion of the power socket having an electrode portion, an abutment portion which abuts on the power socket, and a grip portion. In a state where the handle is rotated to such an angle that the handle is at substantially right angles to the power socket, the abutment portion abuts on the power socket, thereby releasing connection between the electrode portion and the terminals or the like.

Abstract: A three-dimensional connector, which is used by a coordinate input device of a touch pad, has a flat conductor cable with an end being connected to the touch pad and another end forming a soldered conductive contact head perpendicular to the flat conductor cable to pass through a support to shorten a length of said conductor cable and enhance electro-conductibility of the connector.

Abstract: A power board includes an on-board connector having an output terminal that is surrounded by a housing made of synthetic resin. The output terminal is arranged in an area of the housing that is farther from the edge portion of a circuit board so that sectional arrangement is provided. The output terminal is thus surrounded by the synthetic-resin housing, and thereby a leak at the output terminal can be prevented. Further, the output terminal is arranged in the limited area of the housing farther from the edge portion of the circuit board, resulting in a long distance maintained between the output terminal and the edge portion of the circuit board, which can effectively prevent the leak.

Abstract: An modular plug includes a plug main body that can be inserted into and removed from a connector; an engaging claw configured to engage the plug main body with the connector; and an operations lever configured to turn off engagement of the plug main body and the connector by the engaging claw; wherein a lock turning-off member is provided at the plug main body so that the lock turning-off member can be slid in inserting and removing directions; an inclination surface of the lock turning-off member is formed in a position facing the operations lever; and the inclination surface operates the operation lever accompanying sliding in the inserting direction of the lock-turning off member so that the engagement of the engaging claw and the connector is turned off.

Abstract: In a color cathode ray tube, the outer diameter of a neck is set at 22 mm-23 mm, the diameter of a pin circle formed by stem pins outside the flare section of a stem welded to an end of the neck is set at a nominal value of 15.24 mm, and the maximum diameter of a base adhered to an outer surface of the stem is set at 23 mm or less. Accordingly, while the neck outer diameter is reduced to reduce the power consumption of the color cathode ray tube, the color cathode ray tube has a high resolution.

Abstract: A protector for cathode ray tube (CRT) lead pins includes a cylindrical body having a central tubular portion with an inside surface, an outside surface surrounding the tubular portion, pin inserting holes concentrically arranged around the central tubular portion for receiving lead pins mounted on a neck portion of a CRT, and a flange portion extending circumferentially at one end of the body. At least the body or the flange includes opposed manually detectable position indicators for orienting the protector with respect to the lead pins of the CRT. The protector can be engaged with the lead pins accurately and rapidly.

Abstract: A hermetic terminal assembly structure adapted to be sealed along the periphery of an aperture in a chamber defining housing wall of a hermetically sealed chamber including a terminal pin sealed by a coalescent aperture seal in the aperture to include inner and outer pin portions, each of which pin portions is surrounded by one of a pair of sleeve members sealingly cooperative with the aperture seal.

Abstract: A connector with a retractable base plate to protect its contact outlets, the connector functioning to ensure connections between various parts of television type cathode ray tubes and correspoding printed circuits, comprises a contact holder casing, a sliding base part supporting the contact holder casing, the sliding base part having hollowed out housings, integral therein, contact outlets into which the housings are respectfully inserted, guiding and click and spring work systems for maintaining said contact outlets in said housing, the aforementioned guiding and click and locking systems functioning to lock the base plate onto the casing whereby pressure brought on the casing perpendicular to the printed circuit causes the base plate coming into contact with the printed circuit to undergo translation, effectuating the passage of contact end pieces from the housing through holes in the base plate whereby the contact outlets can be brazed.

Abstract: A base for a CRT has an outside diameter which is less than the outside diameter of the tube neck. A plurality of resilient detents are integral with the base and act against the exhaust tubulation to help retain the base on the neck of the tube. A silo is integral with the base and surrounds the high voltage pin. The pins freely pass through pinslots to avoid bending the pins when putting the base onto the neck. The pinslots are configured to facilitate the reception of bent or misaligned pins.
