  • Publication number: 20030186596
    Abstract: An electrical terminal and a system of the terminal and a housing is disclosed as an example of the present invention. The electrical terminal and the housing have a number of advantages including being sufficiently stiff to prevent arcing and physical damage to the electrical terminal upon being exposed to surge current/voltage. The terminal includes a contact with a base portion from which two spaced apart arms extend outwardly. First portions of the arms are generally parallel to one another. Second portions of the arms converge toward each other and then flare outwardly along third portions of the arms. At the junction of the second and third portions, there is a contact region formed to receive the lead of a surge protection device. The tenminal is enclosed in an opening in the electrically insulative housing, the opening being bordered by walls closely adjacent to the first portions of the arms. The spacing of the walls from the arms is about 0.001 inches on each side of the terminal.

    Abstract: The present invention relates to an electrical connector which at least partially receives a foil with printed conductors embedded therein, and comprises an insulating housing with an insertion aperture for the foil and at least one foil contact with a contact section for contacting the printed conductors. The foil contact has a connection section for connection to an electric component and an actuating zone to receive mechanical pressure. To ensure reliable contacting and inexpensive production and simplified assembly of the components, the foil contact is bent as one piece from a punched spring sheet and has at its first contact arm an end section which is bent approximately to a U-shape, which can be brought into contact with the two contact arms by mechanical pressure. According to the invention, the connector also comprises an actuator to actuate this foil contact in which retaining webs are integrally formed which penetrate the foil when the actuator is closed.

  • Patent number: 6537111
    Abstract: An electric contact plug receives a tip jack input at a plug-in zone, and completes the electrical connection via a connection zone to an electronic component, such as a printed circuit board. The electric contact plug also includes an intermediate zone, connected between the plug-in zone and the connection zone. The intermediate zone is designed to deform mechanically when the plug-in zone is subjected to vibrational stresses, as typically occur in a motor vehicle. As a result, the tip jack is held securely within the plug-in zone, while the intermediate zone absorbs the effects of the vibrational stresses. Thus, the inventive electric contact plug avoids the problems of friction and corrosion within the plug-in zone. Moreover, this electric contact plug is compatible with thick-wire bonding, and can be manufactured economically.

  • Patent number: 6375488
    Abstract: A connector has a reduced height housing, and a reduced risk of breaking an electric wire. Electric wires Fc are connected by gripping pressure between connecting members 46 located at tips of arm members 42 of terminal fittings 40. When the terminal fittings 40 are in an attached state with a connector housing 10, the pair of arm members 42 are aligned in a width-wise direction of a flat cable F. Consequently, the height of the connector housing 10 can be reduced. Further, when the electric wires Fc are to be connected with the terminal fittings 40, these electric wires Fc merely need to be moved in a direction at a right angle to their direction of distribution until they are gripped between the connecting members 46. When this connection takes place, a pulling force is not exerted on the electric wires Fc in a length-wise direction. Consequently, breakage of these electric wires Fc can be avoided.

  • Publication number: 20010049238
    Abstract: An electric contact plug receives a tip jack input at a plug-in zone, and completes the electrical connection via a connection zone to an electronic component, such as a printed circuit board. The electric contact plug also includes an intermediate zone, connected between the plug-in zone and the connection zone. The intermediate zone is designed to deform mechanically when the plug-in zone is subjected to vibrational stresses, as typically occur in a motor vehicle. As a result, the tip jack is held securely within the plug-in zone, while the intermediate zone absorbs the effects of the vibrational stresses. Thus, the inventive electric contact plug avoids the problems of friction and corrosion within the plug-in zone. Moreover, this electric contact plug is compatible with thick-wire bonding, and can be manufactured economically.

  • Patent number: 6325681
    Abstract: An electrical cable connector comprises a plurality of female contacts 20 and a plurality of cables 50. The female contacts 20 are aligned and retained in a row extending in a right and left direction in an insulative housing 10, and one end of each cable is connected to a corresponding female contact in the insulative housing 10. Each of the female contacts comprises a base portion 21, which is fixed in the insulative housing 10 and to which the core wire of a corresponding cable 50 is connected, and a resilient arm portion 25, which is continuous from the base portion 21 and extends along the base portion 21 with a predetermined distance therebetween. When this connector is engaged with a matable connector, each female contact receives and holds a corresponding male contact of the matable connector in a space between the base portion 21 and the resilient arm portion 25, thus establishing the electrical connection of the female and male contacts.

  • Patent number: 6296533
    Abstract: An electrical receptacle contact is provided having contact beams which are asymmetrically opposed, defining a terminal receiving section therebetween. Asymmetrically opposed contact beams may have various widths to provide an appropriate spring force for a selected plating material, while ensuring that the receptacle contact maintains the same overall dimensional shape as contacts made with a different plating material. Although allowing for variable spring rate in limited dimensioned contact, susceptibility of fracture of the contact of the present invention during forming is minimized.

    Abstract: A connector contact has a main body portion, a pair of elastic pieces extending like beams on the same side from two sides of the main body portion, and contact portions respectively formed at distal ends of the elastic pieces, to come into contact with a male contact inserted between the contact portions. The pair of elastic pieces have, at their distal ends, protrusions at which the contact portions are to be arranged and each of which projects in a lateral direction opposite to the other elastic piece. The pair of elastic pieces are deformed by twisting or bending, so that the contact portions oppose each other.

  • Patent number: 6247976
    Abstract: A female terminal comprises a base, a pair of mounting portions vertically extending from opposite edges of the base and a pair of mating portions extending from other opposite edges of the base in a direction opposite from that of the mounting portions. The mating portion forms a spring arm, a contact section and a guidance portion. The contact sections define an angle therebetween, and the angle between the contact sections approaches zero when a male terminal is inserted into and connects with the female terminal, thereby causing the male terminal to connect with the contact sections substantially in a plane. Thus, the male terminal and the corresponding female terminal are reliably connected.

  • Patent number: 6227916
    Abstract: A novel electrical connector structure is disclosed. The electrical connector includes a socket portion for receiving therein an electrical plug, a conductive terminal for clamping a metal pin of the electrical plug in the socket portion, and a wrapping portion for securing and protecting the conductive terminal in the socket portion. By designing the shape of the conductive terminal to be relatively narrow in front and relatively wide in rear, and modifying the opening shape of the socket portion accordingly, the conductive terminal can be smoothly inserted into the socket portion so as to allow the electrical connector to be easily assembled. Furthermore, the socket portion can be integrally formed because the conductive terminal is combined with the socket portion by direct insertion operation rather than conventional placing and covering operations.
