In order to achieve the above described object, a secondary battery case according to the present invention includes: a can configured to have a lower plate and a raised side wall which extends upward from the lower plate and has an inner space of which the upper side is open; and a cap configured to have an upper plate and a dropped side wall which extends downward from the upper plate, has an inner space of which the lower side is open, and is inserted into the inner space of the can in order to isolate the inner space of the can from the outside so that the lower end of the dropped side wall is received by the upper surface of the lower plate. The present invention may include a fastening strengthening unit which surrounds a partial section of the dropped side wall with a partial section of the raised side wall so that fastening and sealing are improved when the can and the cap are fastened with each other. According to the secondary battery case of the present invention, a connection structure for the can and the cap is simplified, and thus product size can be reduced, the fastening and the sealing between the can and the cap are improved, and conductivity with an electrode assembly is improved.

The present invention pertains to a conductive pattern having a layer (A) comprising a base, a receptive layer (B) and a conductive layer (C), said conductive pattern being characterized in that the receptive layer (B) is formed by applying a conductive ink containing a conductive substance (c), which forms the conductive layer (C), to the surface of a resin layer (B1) containing a vinyl resin (b1) obtained by polymerizing a monomer mixture containing 10 mass% to 70 mass% of methyl (meth)acrylate, and then cross linking the resin layer (B1).

The invention relates to a crimping die part and a crimping die. In one aspect, the crimping die part is provided; the crimping die part can comprise a die body; the inner wall of the die body can comprise an inner surface partially defining a crimping cavity; and the crimping die part is characterized in that the inner surface of the inner wall of the die body can be provided with a protruding part which protrudes inwards in the radial direction from the inner surface. According to the crimping die part and the crimping die, while the manufacturing difficulty and / or the manufacturing cost ofthe crimping die part / the crimping die is obviously reduced, the drawing tolerance and / or the power-on capacity between a cable and a terminal or cables which are crimped together can be improved.

[Problem] When conductors are connected to one another, conventionally the conductors are plated with silver or tin, which are conductive and corrosion resistant, in order to prevent the formation of oxide films on the surface of the conductors, and to prevent electrolytic corrosion resulting from different types of metal coming into contact with one another. Plating the entire conductor results in an increase in cost, and partial plating requires the addition of a masking operation, and depending on the shape of the conductor, may result in a cost that is higher than coating the entire conductor. [Solution] According to the present invention, when conductors are to be connected using a fastener, an electrically conductive member for connection of conductors is interposed between the two conductors. A plurality of protruding portions are formed on the surfaces, of the electrically conductive member for connection of conductors, that come into contact with the conductors. A plating layer is formed on the contacting surfaces that include the protruding portions, by means of an electrically conductive and corrosion-resistant plating process. When the conductors are connected to one another using a fastener, the contact pressure of the protruding portions causes oxide films on the electrically conductive member for connection of conductors to be removed.
