A connector includes a sphere serving as a contact portion and a support member rotatably and elastically supporting the sphere. The sphere and the support member form an electrical connection path. The connector may further include a housing fixed to the support member, wherein the housing has a through hole sized such that the sphere cannot pass therethrough, and the sphere protrudes through an opening of the through hole to outside of the housing.

An electrical connector includes an insulating body, and multiple terminals accommodated therein. Each terminal has a connecting portion, two side portions bending backward and extending from left and right sides of the connecting portion, two extending portions provided opposite to each other and extending downward from the two side portions, and two embracing arms connected to lower ends of the two extending portions. The two embracing arms jointly embrace a solder ball, which has a first vertical central plane in a front-rear direction. The two embracing arms are located on two sides of the first vertical central plane. A distance between the front ends of the two embracing arms is less than a distance between the rear ends of the two embracing arms of each terminal. The front ends of the two embracing arms are attached with solder liquid formed by melting of the solder ball during soldering.

An electrical connector and an electrical connector assembly are provided. The electrical connector assembly includes: a mating assembly including a support plate and multiple insertion portions provided on the support plate and protruding downward out of the support plate; and an electrical connector. The electrical connector includes: a substrate, provided with multiple accommodating holes running through the substrate vertically; and multiple terminals accommodated in the accommodating holes. Each terminal has a base and two clamping portions configured to clamp a corresponding insertion portion. The two clamping portions are located in front of the base. A top end of the base is lower than top ends of the two clamping portions. When the two clamping portions jointly clamp the corresponding insertion portion, a portion of the corresponding insertion portion lower than the top ends of the clamping portions is located right above the base of an adjacent terminal.

An electrical connector includes an insulating body and multiple terminals accommodated in the insulating body. Each terminal has a base portion, a strip connecting portion extending upward from the base portion to be connected to a strip, and an elastic arm extending from the base portion. The elastic arm has a first tearing edge torn from the strip connecting portion, a second tearing edge torn from the strip, and a blanking edge blanked from the strip. The second tearing edge or the blanking edge has a dividing point. When each terminal is connected to the strip and expanded in a same vertical plane, the dividing point and a top point of the first tearing edge are vertically aligned. After the elastic arm is formed by bending, the dividing point and the first tearing edge are both located at a back side of the strip connecting portion.

An arrangement of components for transferring electric current from a current-feeding component to a current-discharging component, including a first component, which feeds current to the arrangement or discharges current from the arrangement. The first component includes a first metallic material and, on at least one surface, has at least one spring lamella composed of the first metallic material and machined out of the first metallic material at the surface. The lamella is machined out of the first metallic material at the surface of the first component such that it is connected monolithically to the first component in a connecting region and, starting therefrom extends as far as a free end and when deflected out of a rest position toward the surface of the first component, exerts a spring force directed away from the surface. A second component is in immediate contact with the lamella of the first component.

A PCB direct connector is directly mounted to a circuit board, and the PCB direct connector includes terminal members arranged in two rows to respectively contact upper conductive patterns and lower conductive patterns provided to an upper surface and a lower surface of the circuit board, and a connector housing configured to accommodate the terminal members therein and allow a connector connection portion formed at one side of an end of the circuit board to be fitted into and released from the connector housing.

An electrical connector for connecting an electronic package to a printed circuit board, includes an insulative housing with a plurality of passageways therein, and a plurality of contacts are retained in the corresponding passageways, respectively. Each contact has a main body and opposite upper and lower contacting arms extending therefrom in a symmetrical manner in the vertical direction. Each of the upper contacting arm and the lower contacting arm has a pair of spring beams spaced from each other. Each beam includes an extension section directly extending from and coplanar with the main body, an oblique section extending from the extension section and a contacting section extending from the oblique section. The distance between the oblique sections of the pair of beams is essentially same with that of the extension sections thereof, while larger than that of the contacting sections thereof.

An electrical connector includes an insulative housing forming plural rows of passageways wherein each row of passageways extends along a transverse direction while the plural rows are spaced from one another in a front-to-back direction perpendicular to the transverse direction. Each passageway is dimension to receive a unified contact having three sets of spring arms spaced from one another in the transverse direction. The three sets of spring arms are categorized with two outer sets and one inner set therebetween in the transverse direction. The pitch between the two neighboring sets of spring arms of each unified contact is essentially one half of the distance between one outer set of spring arms of one unified contact and another outer set of spring arms of the neighboring unified contact.

A connector assembly including a female connector and a male connector. The female connector and the male connector both can rotate relatively. The female connector includes a plurality of female conductors, and the male connector includes a plurality of male conductors. When the female connector and the male connector both rotate relatively, each of the female conductors can be electrically connected to at least one of the plurality of male conductors, thereby assuring electrical connection between the female connector and the male connector. This configuration, when being applied to a wearable device, allows function elements of the wearable device to be expanded and modified.
