An electrical connector includes: an insulating housing; and plural terminals held in the insulating housing and arranged in terminal pairs, each of the terminals including: a holding portion held in the insulating housing; a cantilever extending forward from the holding portion, a slot being provided on the cantilever; a contact portion at a front of the cantilever; and a mounting portion for mounting on a circuit board; wherein the slot extends to the contact portion; and in each terminal pair, a first distance from a center of the contact portion of one terminal thereof to a center of the contact portion of the other terminal thereof is less than a second distance from a center of the mounting portion of one terminal thereof to a center of the mounting portion of the other terminal thereof.

A press-fit insertion method is provided. The press-fit insertion method includes loading press-fit pins into a connector, heating a printed circuit board (PCB) defining plated through holes (PTHs) into which the press-fit pins are insertable and pressing the connector onto the PCB to insert the press-fit pins into the PTHs with the PCB remaining heated.

A method for inserting preformed solder members into connector pins for use with electrical connectors. The method generally includes a connector pin having an open cavity at one end, into which a preformed solder member can be first inserted and then pressed, rather than melted, in place, such that voids and air spaces within the cavity are substantially eliminated. The method allows for inserting solder members in high quantities, where the preformed solder members are placed in a fixture and the fixture is placed on a shaker table, so that solder members can be inserted into large numbers of connector pins that are pre-installed in connector grommets, largely simultaneously.

An electrical contact assembly includes an electrically nonconductive base, a first electrical contact supported by the base and a second electrical contact supported by the base such that the first contact and the second contact are separated by a space. The first electrical contact is configured to engage a first external conductive circuit element and the a second electrical contact is configured to engage a second external conductive circuit element. The first contact and the second contact are configured such that a portion of the first contact and a portion of the second contact converge as the base moves in a first direction relative to the first and second external conductive circuit elements and diverge as the base moves in a second direction relative to the first and second external conductive circuit elements.

A printed circuit board (PCB) device including one or more insulating layers and one or more conducting layers arranged to form a layer stack; and one or more blind holes disposed along a side edge of the layer stack and parallel to a plane of the layer stack. Each of the one or more blind holes along the side edge of the layer stack is configured to receive a pin. Each pin can make an electrical connection with a corresponding blind hole.

An electronics device includes a folded printed circuit board which is folded about at least one fold region which defines a first section and a second section. A housing has a plurality of side portions. The first section of the folded printed circuit board is secured along an outer surface of a first side portion of the plurality of side portions. The housing further includes an interior. At least one first slot is defined within the interior and disposed along or near a second side portion arranged opposite the first side portion. At least one first pin member is disposed partly within the at least one first slot and extends therefrom. A distal end portion of the at least one first pin member engages with the second section of the folded printed circuit board so as to hold the second section in position over the interior of the housing.

In a control unit having a press-fit structure, a substrate includes: a connected portion to which the press-fit terminal is connected; and a guide portion extending from the substrate around the connected portion. The press-fit terminal includes: a tip end portion; a contact portion adjacent to the tip end portion; and an enlarged portion. The guide portion includes: an opening portion; a guide hole extending from the opening portion to the substrate; a tapered surface formed on an inner side of the opening portion; and a reduced-hole portion formed continuous to the tapered surface. The tip end portion of the press-fit terminal is configured such that the contact portion is positioned with respect to the connected portion while the enlarged portion is guided by the tapered surface and an inner wall of the reduced-hole portion.

A preformed solder-in-pin system for use with electrical connectors. The preformed solder-in-pin system generally includes a connector pin having an open cavity at one end, into which a preformed solder member can be first inserted and then pressed, rather than melted, in place, such that voids and air spaces within the cavity are eliminated. The preformed solder-in-pin system can be assembled in high quantities, where the preformed solder members are placed in a fixture and the fixture is placed on a shaker table, so that large numbers of connector pins, pre-installed in connector grommets, can be inserted largely simultaneously.

This invention provides a method for mounting an electroacoustic component on a PCB and an electroacoustic component structure, so as to improve the problem that the traditional electroacoustic component affects the electrical characteristics due to the high temperature baking action in a reflow oven. The method comprises a step of separating and constructing a housing of the electroacoustic component. The housing comprises a shell seat and a base seat, the shell seat is provided with a plurality of sound producing components, and the base seat is provided with at least two conducting terminals for adhering the base seat to the PCB. The conducting terminals on the base seat and the at least two contacts on the PCB are adhered to each other and electrically connected in the reflow oven, and then the shell seat and the base seat are combined to make the shell seat and the base seat with the PCB combined outside the reflow oven into a single body to form an electroacoustic component that is mounted on the PCB.

A component mounting board includes first and second substrates, a connection substrate, an interposer, and an electronic component. The first substrate has first and second surfaces opposing each other, a first side surface between the first and second surfaces, and a first signal pattern. The second substrate is disposed on the first substrate, has third and fourth surfaces opposing each other and a second side surface between the third and fourth surfaces, and includes a second signal pattern. The connection substrate is bent to connect the first and second side surfaces, and the interposer is disposed between the first and third surfaces and electrically connects the first and second signal patterns. The electronic component is mounted on at least one of the first to fourth surfaces.
