Abstract: An elastic electrical contact device and a contact conductor are introduced. The elastic electrical contact device includes two contact conductors. Each contact conductor includes a head and an electrical contact portion integrally connected with each other. The electrical contact portion has a cross section shaped as a curved bend and has a guide groove formed thereon. The electrical contact portion is bilaterally symmetrical along a second central axis, wherein a first central axis and the second central axis are parallel to each other and non-coaxial. The electrical contact portions of the two contact conductors are disposed to have openings thereof face each other and are mutually connected in respective guide grooves, are mutually slidable to extend and retract relative to each other, and are sleeved by an elastic reset member to enable the two contact conductors to be elastically reset when extending and retracting relative to each other.

Abstract: A case structure for card-type electronic product includes an intermediate frame having insertion slots spaced thereon; a lower cover connected to a lower side of the intermediate frame by lower hooking members upward inserted into the insertion slots, and each of the lower hooking members including two spaced latch legs; and an upper cover connected to an upper side of the intermediate frame by upper hooking members downward inserted into the insertion slots corresponding to the lower hooking members, and each of the upper hooking members including two laterally outward extended latch hooks. When the upper and lower covers are assembled to the upper and lower sides of the intermediate frame, the latch hooks of the upper hooking members are abutted on lower edges of the latch legs of the lower hooking members to firmly hold the lower cover to the upper cover in three directions.
