Abstract: A tulip contact comprises a plurality of outer contact fingers and inner contact fingers. The outer contact fingers forming a shape of the outer surface of fixed contact in order to make the contact surface of each of these fingers contact with the outer surface of fixed contact. The inner contact fingers forming a shape of the inner surface of fixed contact in order to make the contact surface of each of these fingers contact with the inner surface of fixed contact. Each said contact finger comprises a first contact bulge for contacting with the surfaces of the fixed contact, and a second contact bulge for contacting with the bushing. And each said contact bulge comprises a contact slot on its surface. The first contact bulges of the outer contact fingers are not at the same cross section with the first contact bulges of the inner contact fingers.

Abstract: An electrical connection passing through a dividing wall contains a contact plate (2) having a base piece (4) covering a surface, and a contact piece (8) connected to the base piece via a connecting piece (6), wherein the perimeter of the base piece, including the attached area of the connecting piece, is held and sealed in the dividing wall (24), and the contact piece has an elastically deformable area (10) exposed for making contact with a component. The dividing wall seals a chamber of a housing in which is located an electrical circuit connected by a contact lug (12) of the base piece (4). Outside the chamber a battery compartment is provided in which is held a battery pressed elastically in position against a facing surface by the spring tongue (10).

Abstract: A lower surface contact type contact which is to be arranged in array on a connector body made of an insulative material, comprising an upwardly projecting contact portion on which a lower surface of an external contact of an electronic part is placed to press the upward projecting contact portion downward; a leftwardly expanding curved spring portion including a downward displacement component for allowing a downward displacement of the contact portion when the contact portion is pressed downward by the external contact and a rightward displacement component for causing a tendency for rightward displacement of said contact portion; and a support post implanted in the connector body and adapted to support the curved spring portion, the support post being displaced leftward when the contact portion is displaced downward, so as to offset the tendenct for rightward displacement.

Abstract: An object of the invention is to quickly supply inexpensive large current terminals without entailing complicated metal-working process and labor. Further, another object thereof is to provide methods of metal-working such terminals. A large current male terminal is constructed by forming a hollow cylindrical electric contact part on one end of a conductive pipe, a hollow cylindrical wire crimping part on the other end thereof, and a collar between the electric contact part and the wire crimping part. The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto.

Abstract: A connector terminal includes a first terminal having a cylindrical tubular portion, and a second terminal that can be connected to the cylindrical tubular portion. An outer terminal member and an inner terminal member for contacting respectively with outer and inner surfaces of the tubular portion are selectively attached to the second terminal. By selecting the two terminal members suitably, designs for respectively accommodating different allowable current values can be easily achieved.
