A terminal assembly structure according to an embodiment of the present invention includes: a crimp terminal having a crimp portion configured to crimp and connect a core wire of an electric wire and a fastening portion configured to be fastened by a fastening member; and a holder having a base portion configured to place the crimp terminal when fastening the crimp terminal to the holder. The holder has a detection rib at a position on the base portion to be oppose to the crimp portion of the crimp terminal, the detection rib being configured to interfere with the crimp portion when misassembly of front and back sides of the crimp terminal to the holder occurs.

A connector includes: a terminal fitting connected to an electric wire; a housing including a housing chamber, an electric wire drawing port, a communication hole, and a counterpart fitting chamber where a gap formed between the counterpart fitting chamber and a counterpart terminal fitting is filled with a first sealing member; a lid member; a second sealing member that fills a gap between these and forms a first sealed space part in the housing with the first sealing member; a waterproof member including one end part in close contact with an end part of the housing, the other end part in close contact with the electric wire drawn from the electric wire drawing port, and a tubular part, the tubular part including a second sealed space part communicating with the first sealed space part through the electric wire drawing port; and a ventilation component.

A terminal assembly structure according to one or more embodiments includes: a terminal having a crimp portion configured to crimp and connect to a core wire of an electric wire and a fastening portion configured to be fastened by a fastening member; and a holder having a base configured to mount the terminal when fastening the terminal to the holder. The holder has a plurality of ribs extending in a fastening direction of the fastening member and arranged around the fastening portion of the terminal when the fastening portion is set and positioned onto the base.

A terminal post assembly for connecting at least one electrical terminal to a substrate. The terminal post assembly includes a terminal post which has a substrate mounting portion, a terminal receiving portion and a cap receiving portion. The substrate mounting portion has a base and a securing portion which is dimensioned to extend through a mounting opening of the substrate. The terminal receiving portion is configured to receive the at least one electrical terminal thereon and make an electrical connection to the at least one electrical terminal. The cap receiving portion has a cap positioned thereon. the cap cooperates with the at least one electrical terminal to retain the at least one electrical terminal in position on the terminal receiving portion to maintain the electrical connection between the at least one electrical terminal and the terminal receiving portion of the terminal post of the terminal post assembly.

Electrical line hardware such as termination arrangements and splices for use with overhead electrical cables that enable the interrogation of the overhead electrical cables through the hardware. The hardware includes at least one port to facilitate access to the strength member of the electrical cable so that interrogation instruments may operatively couple to the strength member and to interrogation elements such as optical fibers associated with the strength member. The interrogation may occur after the overhead electrical cable has been fully tensioned and secured by the hardware, e.g., secured to a support tower.

Discussed is a battery pack including a plurality of battery cells coupled to a busbar plate and a battery pack case configured to receive the plurality of battery cells, wherein an external coupling portion of the busbar plate is disposed at the outer surface of the battery pack case so as to be exposed therefrom, and the external coupling portion is coupled to a ring terminal by fastening using a rivet without being deformed. The external coupling portion of the busbar plate is formed so as to be short such that opposite surfaces of the ring terminal can be coupled to the busbar plate.

The subject disclosure relates to a water-tight sealed stud assembly for high current applications. The water-tight sealed stud assembly can include a stud, a sealing ring, a sleeve, and a body. The stud may have a stud base and a thickened portion having an annular groove. The sealing ring may be disposed in the annular groove. The sleeve may be disposed circumferentially around the stud and made of a conductive material. The body may be disposed circumferentially around the sleeve and made of a non-conductive material. Systems and methods are also provided.
