Abstract: To provide a speaker cable plug which is high in performance and easy to use, a speaker terminal for connection to such plug, and a speaker terminal system using such plug and terminal as a set.

Abstract: A connector including a plurality of terminal wires forming gently-sloping hills in a longitudinal direction and having curved front and rear opposite end portions and wire retaining bodies each of which has substantially the same length as the wires to partially cover front half sides and rear half sides of one faces of the wires without contact and to restrain and retain intermediate portions of the wires. The two wire retaining bodies are combined into combined wire retaining bodies in such a manner that the curved opposite end portions of the retained wires face each to form terminal pinching portions. The combined wire retaining bodies are housed in a cylindrical connector casing having front and rear opposite open ends. The front and rear terminal pinching portions of the retaining bodies face the front and rear open end portions of the connector casing.

Abstract: It is an object of the present invention to achieve solderless connection with a connector of a type to be plugged in a board and a plug to be plugged in the connector, improvements having been made in a cost of metal molds and a cost of manufacturing of the connector by simplifying structures of the metal molds and making it possible to assemble the connector on an automatic assembly line. To achieve this object, the invention provides the connector including a plurality of terminal wires forming gently-sloping hills in a longitudinal direction and having curved front and rear opposite end portions and wire retaining bodies each of which has substantially the same length as the wires to partially cover front half sides and rear halt sides of one faces of the wires without contact and to restrain and retain intermediate portions of the wires.

Abstract: A plug for the speaker cables of the invention comprises a plug main body involving terminal loading slots for positive and negative polarities on the front thereof, loading slots for cables in response to both polarities on the rear thereof, and a hollow inside thereof, wherein first tongues for holding terminals functioning to hold speaker terminals are inserted from the terminal loading slots from the external surface thereof by spring action, second tongues for holding cables connected to the tongues for holding terminals and functioning to hold stranded wires of speaker cables are inserted from the cable loading slots from the external surface thereof by spring action, and third tongues for holding cables are formed so as to expand sections for holding cables by operating pieces disposed so as to be exposed outside the plug main body.

Abstract: Contacts are provided wherewith attachment to a board can be made with adequate attachment strength, without requiring soldering, which can be easily removed from the board without causing damage to occur. Parts of wiring rounds 37 positioned at the extreme diagonally lower right point on a printed circuit board 31 are clamped from above and below by the upper portion of a wiring round side contact part W, indicated by solid lines, facing on a slit 39 positioned at the extreme diagonally lower right point in a base 19, and by the lower portion of a wiring round side contact part W indicated by broken lines. The part of the wiring rounds 37 is clamped by the wiring round side contact part W, by spring forces that operate in directions to tighten that part, which spring forces develop in the upper portion and the lower portion of the wiring round side contact part W.
