A connector includes a base member and a contact connected to a connection object, a first surface of the base member making contact with a bottom surface of a sheet-like conductive member, the contact being fixed to the base member by a deformed portion of the projection in a state where a root portion of the projection is accommodated in a projection accommodating portion with the sheet-like conductive member being sandwiched therebetween, an inner peripheral surface of the projection accommodating portion making contact with a flexible conductor of the sheet-like conductive member, whereby the connection object is electrically connected to the flexible conductor via the contact.

This utility model provides a wiring terminal, used for receiving and connecting to a conducting wire, the wiring terminal including: a housing, provided with a mounting channel and an insertion hole communicating with the mounting channel for the conducting wire to be inserted; a conductive piece and a clamping piece, both of which are arranged in the mounting channel, where the conductive piece and the clamping piece cooperate to form a natural state in which the conducting wire placed in the mounting channel is clamped between the clamping piece and the conductive piece through elastic abutment and a pressed state in which the conductive piece and the clamping piece are controlled by an external force to deform in a direction distal from the clamped conducting wire.

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.

A rivet assembly for securing a wire in electrical communication with a substrate having a hollow cylindrical body with a first opening at a proximal end and a second opening at a distal end. The rivet assembly further includes a wire with a portion in electrical communication with the cylindrical body. The rivet assembly yet further includes a compression mechanism configured for use selectively compressing the cylindrical body along an axial direction. Compression of the cylindrical body can cause diametric expansion of an outer diameter of the cylindrical body to retain the cylindrical body within a substrate. The rivet assembly additionally includes wire retention structure configured for holding the wire in electrical contact with the compressed cylindrical body.

An electrical power contact, for a fixed electrical outlet of a vehicle for connecting a battery of the vehicle to an external DC electrical source, consists of two conductive parts mechanically cold-assembled through snap-riveting, connecting part and a connection terminal. A first of the two conductive parts is provided with a shoulder and with a protruding portion protruding with respect to the shoulder, the other conductive part comprising a wall having a bearing face bearing against the shoulder and a free face opposite the bearing face. The wall is has a through-hole opening onto a counterbore forming a recess for the free face. The protruding portion passes through the through-hole and has a head housed in the counterbore.

The invention discloses a pulling rivet for fasten-connecting a conductive material. It consists of a rivet and a lantern ring, wherein the rivet comprises a dead head, a polish rod, a locking groove, a pulling groove and a short tail, the lantern ring comprises a flange, a deformation area and a clamping tooth, and a sharp protrusion is arranged on a contact surface of an inner side of the dead head and a fasten-coupling piece. The sharp protrusions of the present invention can be embedded into the surface of the fastening piece to prevent the sliding between the fasten-coupling piece and the rivet, and because the sharp protrusions are embedded into the surface of the fasten-coupling piece to form a tightly fitted whole, which improves the conductivity of the rivet and the frame.

A manufacturing method for the secondary battery includes a first preparation step for inserting a terminal formed in an oval like shape and having a cylindrical shaft part into an attachment hole formed on a sealing plate of the secondary battery, a second preparation step for arranging a conductive member on a surface at a side where the shaft part of the sealing plate protrudes, a first caulking step for using a caulking tool that includes a tip end part formed in an oval like shape and includes a base end part formed in a complete round shape whose diameter is larger than the tip end part, to insert the tip end part into the shaft part, so as to make the base end part expand an inner diameter of the shaft part, and a second caulking step for pressing an expanded portion of the shaft part to be flat.
