An electrical power connector and an electrically conductive terminal are provided. The electrical power connector includes an insulating housing, multiple electrically conductive terminals, and at least one position fixing member. The insulating housing includes multiple column bodies and a convex rib structure, the column bodies extend in a first direction and are arranged at intervals, and the convex rib structure extends in a second direction and is formed in an intersecting arrangement. An inside of the insulating housing has multiple tunnels that correspondingly penetrate through the column bodies in the first direction. Multiple grid passages are formed by the convex rib structure. The electrically conductive terminals are respectively mated in the grid passages and the tunnels. The electrically conductive terminals are each connected to a cable. The at least one position fixing member is embedded on at least one side of the convex rib structure.

An electrical power tap connector for a model vehicle is provided including a first power tap housing. The first power tap housing contains a power tap terminal configured to electrically couple with a connector terminal of an electrical connector. The power tap connector also includes a second power tap housing releasably securable to the first power tap housing and a releasable locking mechanism configured to physically secure the power tap connector to the electrical connector. Wherein the power tap terminal is configured to electrically couple with the connector terminal via a non-mating end of the electrical connector.

Method for crimping a cable terminal onto an electric cable includes providing an electric cable having an outer insulation sheath and at least one conductive strand with a sheathed portion, and providing a terminal having shrink wings and provide a gasket having a sealing portion and a shrink portion. The method also includes stripping the electrical cable so that a stripped portion is formed, positioning the shrinkage portion of the joint so that it directly overlaps the stripped portion of the cable without the shrinkage portion overlapping the sheathed portion of the cable, and fully crimping the shrink wings onto the shrink portion of the joint without the shrink wings covering the sheathed portion of the cable.

A terminal-equipped wire 1 is provided with a terminal 10 and a coated wire W pulled out rearward from the terminal 10. The terminal 10 includes a wire barrel portion 20 to be crimped to a core wire W1 in an end of the coated wire W. The wire barrel portion 20 includes a crimping bottom surface 22 and a pair of wire barrel pieces 21 extending from both side edges of the crimping bottom surface 22. A front end part of the core wire W1 is covered by front end parts of the pair of wire barrel pieces 21 of the wire barrel portion 20. A confirmation hole 40 enabling confirmation of the front end part of the core wire W1 is provided in the crimping bottom surface 22 of the wire barrel portion 20.

A crimping terminal includes a conductor crimping portion, the conductor crimping portion including: a bottom plate on which a conductor of an electric wire is disposed; and a pair of conductor tightening pieces extending from both side edges of the bottom plate, the conductor crimping portion configured to be crimped and connected to the conductor by tightening the conductor in a state where the conductor is covered with the conductor tightening pieces. The conductor crimping portion includes a serration extending in a groove shape across the pair of conductor tightening pieces and the bottom plate in a direction intersecting an extending direction of the conductor to be disposed on the bottom plate, and a width of an opening of the serration is equal to or larger than a width of a bottom surface of the serration.

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.
