An electrical connector assembly for electrically and mechanically connecting a component to a power source is disclosed. The connector assembly includes a male terminal with side walls defining a receiver. The side wall includes a contact arm that extends across an aperture in the side wall. The assembly also includes an internal spring member dimensioned to reside within the receiver of the male terminal. The spring member has at least one spring arm that extends from a base portion. The assembly further includes a female terminal with a receptacle dimensioned to receive both the male terminal and the spring member residing within the receiver of the male connector to define a connected position. In the connected position, the spring arm exerts an outwardly directed biasing force on the contact arm of the male terminal to outwardly displace it into engagement with an inner surface of the receptacle to ensure connectivity.

An electrical connector system for electrically and mechanically connecting with a component in a motor vehicle is disclosed. The connector system includes a motor vehicle component and a male connector assembly with a male housing that receives a male terminal. This terminal includes a receiver and side walls with a contact arm that extends across an aperture in the side wall. An internal spring member with at least one spring arm resides within the male terminal receiver. A female connector assembly includes a female terminal with a receptacle that receives both the male terminal and the spring member. A female housing receives the female terminal and an extent of the male connector assembly. When the connector system moves from the partially assembled state to a connected position for connection of the vehicle component, the male connector assembly is inserted into female housing, the contact arm is brought into sliding engagement with an angled internal segment of the female housing, and the contact arm is inwardly displaced as the contact arm slidingly engages with the angled internal segment.

An electrical female terminal for mating with a connector assembly generally including a main body, a two-bodied spring, and a wire fastening portion. A protrusion extends from an unattached end portion of the lever member, the protrusion having faces angled relative to each other to efficiently deflect the lever member upwards when the protrusion interacts with an internal protrusion of a housing or a connector assembly. A top portion of the retainer member of the electrical female terminal, located above the two-bodied spring, has a dimple portion. The terminal face or leading end portion of the electrical female terminal is prevented from damaging or cutting a silicone seal. The overstress feature of the tang member of the lever is improved upon by relocating and reshaping the protruding member thereof. The configuration or shape of the cross-section across the upper portion and the support member at the front end portion of the main body of the electrical female terminal is substantially U-shaped. The configuration or shape of the cross-section across the attached end portion of the lever member of the electrical female terminal is also substantially U-shaped. The electrical female terminal is formed as a continuous and contiguous single construction having included therein at least the main body, the two-bodied spring, and the wire fastening portion and/or the lever member (or tang member), along with the neck member that joins the main body and the wire fastening portion.

A top portion of the retainer member of the electrical female terminal, located above the two-bodied spring, has a dimple portion to increase the number of contacts to an upper spring of the two-bodied spring, so as to increase the stiffness of the two-bodied spring. The terminal face or leading end portion of the electrical female terminal is prevented from damaging or cutting a silicone seal, which seals the connector assembly from environmental contaminants, during mating therewith by providing thereon a recessed top face portion and a recessed bottom face portion. The overstress feature of the tang member of the lever is improved upon by relocating and reshaping the protruding member thereof.

A male terminal fitting is provided with a base wall extending in a front-rear direction, and a plate-like tab portion extending forward from a front end part of the base wall. The tab portion includes a first wall portion extending forward from the front end part of the base wall, a second wall portion facing the first wall portion, a coupling wall portion coupling side edges on one side, out of both left and right sides, of the first and second wall portions, and a contact wall portion extending from a side edge on the other side, out of the both left and right sides, of the first wall portion toward the second wall portion and abutting on the second wall portion.

A battery pack adapter system includes a device that allows different sized and shaped battery packs to be converted for use with multiple power tools from different brands. In one embodiment, a drill battery and drill are joined together through means of the battery pack adapter device. This allows the drill battery to power the drill even though the battery and drill have different configurations. The battery pack adapter device includes metal electrical connectors that extend from a top end of the device towards a bottom end of the device. The metal electrical connectors transfer the electrical energy from the battery to the power tool through by means of the adapter.

A connector 10 is provided with a terminal 11, a die-cast member 13 for surrounding an outer periphery of the terminal 11, a dielectric 12 to be arranged between the terminal 11 and the die-cast member 13, and a housing 14 into which the die-cast member 13 is mounted. The die-cast member 13 includes a locking protrusion 37, and the housing 14 includes a locking recess 49 recessed in a mounting direction of the die-cast member 13. The locking protrusion 37 is press-fit into the locking recess 49. A closing portion 53 shut off from outside is formed between a tip part of the locking protrusion 37 in the mounting direction and a back end part of the locking recess 49 in the mounting direction.
