A connecter terminal structure includes: a male housing of a male connecter; a male terminal accommodated in the male housing and including a first electrical contact portion; a stepped shaft portion formed at a tip end of the first electrical contact portion; a hood portion surrounding the first electrical contact portion; an annular terminal spring externally fitted to the stepped shaft portion; and an insulating cap fixed to a tip end of the stepped shaft portion and configured to hold the annular terminal spring. The connecter terminal structure further includes: a female housing of a female connecter; a female terminal accommodating portion configured to be fitted into the hood portion; and a female terminal accommodated in the female terminal accommodating portion and including a second electrical contact portion having a tubular shape to allow the first electrical contact portion to be inserted therein.

An electrical junction box includes: a first housing configured to hold a first terminal having a flat plate shape; a second terminal configured to allow the first terminal to be inserted thereinto such that the second terminal is conductively connected to the first terminal when the first terminal is inserted into the second terminal; and a second housing configured to be engaged with the first housing. The first housing has a first space defining, together with a second space of the second housing, a space configured to accommodate the second terminal. The first space is configured to accommodate a part of the first terminal. When the first housing is engaged with the second housing, the first terminal is allowed to be inserted into the second terminal such that the first terminal and the second terminal are conductively connected.

A self-lubricating connector with a housing having a contact receiving cavity with a contact provided therein. A lubricating device is positioned in the housing proximate the contact. The lubricating device extends into the contact receiving cavity and has lubricant provided therein. The lubricant from the lubricating device is deposited or on the outside surface of the contact as the contact is moved between the first position and the second position, reducing wear on the contacts as the contacts are moved between the first position and the second position.

A preformed solder-in-pin system for use with electrical connectors. The preformed solder-in-pin system generally includes a connector pin having an open cavity at one end, into which a preformed solder member can be first inserted and then pressed, rather than melted, in place, such that voids and air spaces within the cavity are eliminated. The preformed solder-in-pin system can be assembled in high quantities, where the preformed solder members are placed in a fixture and the fixture is placed on a shaker table, so that large numbers of connector pins, pre-installed in connector grommets, can be inserted largely simultaneously.

The present invention provides a contact member that strikes a balance between low electrical resistance and sliding durability under the condition of load as low as about 0.1 N. A contact member of the invention has a metal base and a coating disposed on at least part of the metal base. The coating contains fluorinated oil having a polar group, and metal particles surface-treated with a fluorine-based compound having a polar group.

A power tool including a housing that has a battery pack receiving portion configured to receive an interface of a battery pack, device contacts extending from the housing and configured to mechanically and electrically engage with the battery pack, and a latching mechanism supported by the housing and including an actuator and a latch member configured to selectively engage the interface of the battery pack. The actuator is pivotable to operatively pivot the latch member.

A terminal equipped electric wire includes an electric wire including: a conductor and an insulating sheath covering the conductor, a part of the conductor extending out of an end portion of the insulating sheath being an exposed portion, a terminal fitting having an electric wire connection portion at a rear side of the terminal fitting, the electric wire connection portion being connected to the exposed portion, a water stop shrinkable tube covering the electric wire connection portion connected to the exposed portion in a watertight manner, a sensor disposed on an outer surface of the water stop shrinkable tube, the sensor contacting the outer surface of the water stop shrinkable tube and a sensor fixing shrinkable tube covering and fixing the sensor on the outer surface of the water stop shrinkable tube.

A separable high-voltage connector assembly which can miniaturize a size by individually separating each first pin of a connector mounted on a board to form multiple small connectors and simplify a process and prevent an error that connectors are incorrectly inserted into each other by forming an inserting connector through fastening and assembling each of individually separated second pins.
