A connection electrode that is formed of solder on an electronic component side and a tip portion of an elastic contact each other at a contact portion. Regarding the elastic contact, a resistive layer is formed in the tip portion, and the tip portion is placed in a clearance of an induction coil. When a predetermined high-frequency current is passed through the induction coil, electromagnetic induction causes the resistive layer to generate heat. Solder that forms the connection electrode is melt, and flows onto the tip portion of the elastic contact. Thus, the tip portion of the elastic contact and the connection electrode can be strongly bonded together at the contact portion that is a single point therebetween.

Method for bonding metallic terminals by using elastic contact

To provide a contact, formed in an amorphous state, having better spring properties as compared to conventional one; a method for manufacturing the contact; a connection device including the contact; and a method for manufacturing the connection device. The present invention provides a contact comprising an elastically deforming portion that includes at least one amorphous part. The elastically deforming portion includes an auxiliary elastic membermade of, for example, NiP (a P content of 15 atomic percent). In this case, an amorphous phaseis predominant in the auxiliary elastic member. This enhances spring properties such as a yield stress.

A connecting unit for establishing a connection with external connecting portions of an electronic device includes a base and a plurality of spiral contactors having a conductive layer and an auxiliary resilient layer. The top face, the bottom face, and both side faces of the conductive layer are completely surrounded by the auxiliary resilient layer. The conductive layer is composed of a material having a specific resistance lower than the specific resistance of the auxiliary resilient layer. The auxiliary resilient layer is composed of a material having a yield point and an elastic modulus higher than the yield point and the elastic modulus of the conductive layer.

Connecting unit including contactor having superior electrical conductivity and resilience, and method for producing the same

A connector for connecting with an external terminal on an electronic component includes a spiral contact which is wound a plurality of turns. The spiral contact has a single projection that projects outwardly toward an outer circumference of the turns. When the spiral contact is in contact with the external terminal, the projection of the spiral contact comes into contact with the external terminal.

Connector

A discontinuous contact region is formed in the vicinity of the tip of a spiral contact towards the center of the spiral. When a spherical contact is pressed into the spiral contact, a contact point P is formed since the angular portion of the tip of the discontinuous contact region comes into contact with the surface of the spherical contact first. Thus, the electrical characteristic, such as the contact resistance, between the spiral contact and the spherical contact becomes constant, and the connections between the two contacts can be stabilized.

A connecting element includes a support member, a flexible substrate wrapped around the support member, and elastic contacts provided on the flexible substrate. A positioning hole is formed in the support member. A first positioning component is positioned and soldered on a metal layer formed on a motherboard, and a second positioning component is positioned and soldered on a metal layer formed on an electronic component. The first positioning component is inserted into the positioning hole in the connecting element, and the second positioning member is fitted to the first positioning component. Accordingly, the connecting element is positioned with respect to both the motherboard and the electronic component.

Connecting element and circuit connecting device using the connecting element

There are provided a connector capable of accomplishing electrical stability between contact members constituting the connector and a base, reduction in manufacturing cost, and simplicity in assembly and a method of manufacturing the connector. A basecomprises a plurality of bump portionsextending from the bonding surface, which contact members are bonded to, toward the opposite surface, and an insulating layer interposed between the bump portions. The contact membersare bonded to the bump portions. Accordingly, since the contact memberscan be surface-mounted on the base, it is possible to enhance the electrical stability between the contact membersand the base

Method of manufacturing a connector

A supporting portion is provided only at a winding start portion side and an outside of the other part of a deforming portion other than the winding start portion side is opened. Thus, adjacent spiral contactors can be arranged to be close to each other. Therefore, a mounting density of a spiral contactor on a guide frame can be increased. Further, since the deforming portion can be arranged at an opened region, a width of the deforming portion can be widened. As a result, the spiral contactor having a large spring constant is provided.

Spiral contactor, contact sheet having spiral contactor, and connecting device having contact sheet

A pin contact of a connector and a method of fabricating the pin contact which enables a substantial decrease of manufacturing cost, and smooth installation of the pin connector without a change in the pitch of arrangement at the time of press-fitting into a pin housing. A flat metal sheet undergoes blanking and pressing to form a narrow piece including a strip portion of decreased area of a fracture. Then an approximately L-shaped connecting portion is bent at right angles to raise the narrow piece sideways. Thereafter the strip portion of the narrow piece is pressed along the direction of rising, to thereby form an approximately cylindrical contact section. A raised piece at the rear of the contact section is provided with a locking section which faces approximately at right angles with the direction of arrangement.

A PC card connector in which a plurality of pin contacts are secured in a pin housing in a predetermined arrangement such that each of the plurality of pin contacts has a long and narrow terminal end protruding out from the pin housing. The front end portion of each terminal end is soldered onto a mounting surface of a printed board. The PC card connector includes first and second pin holders secured to the pin housing such that bottom surfaces of the pin holders are positioned opposite the mounting surface of the printed board, each of the first and second pin holders having a number of parallel guide grooves for receiving the terminal ends of the plurality of pin contacts. The bottom surfaces of the first and second pin holders are in resilient contact with the front end portions of the terminal ends, and the first and second pin holders are secured to the pin housing such that they are disposed, respectively, at the front and at the back of the pin housing, respectively, along the direction of insertion and removal of a PC card.

A PC card wherein a housing of a socket connector is provided with a guide boss and a stopper protruding on the circuit board side, and with a cutout for fitting the guide boss in the circuit board. In this cutout the guide boss is fitted to position the socket connector in the direction of x. And the forward end of this stopper is held in contact with the circuit board to position in the direction of y, thus facilitating positioning of a socket connector in relation to a circuit board without a fear of socket connector displacement in subsequent processes.
