A connector assembly includes an insulative housing, first and second conductive ground wafers (see e.g., 661 and 663) and a plurality of grounding links. The insulative housing has a plurality of conductive signal terminals disposed therein (see e.g., 662). The insulative housing has opposite side surfaces and a plurality of openings therein extending between the side surfaces. The second ground wafer is spaced from and parallel to the first ground wafer. The grounding links are electrically connected to one of the ground wafers and extend towards another of the ground wafers and extend through the openings in the housing.

An electrical connector including a substrate, a pitch transformation routing assembly formed on the substrate and including pitch transformation routing members, a first set of contact members where each contact member extends away from a first end of a corresponding pitch transformation routing member, and a second set of contact members where each contact member extends away from a second end of a corresponding pitch transformation routing member. Each pitch transformation routing member includes multiple routing sections, where each routing section extends in the first direction or the second direction. In a first subset of the pitch transformation routing members, the pitch transformation routing members have routing sections with different dimensions in the first direction and the second direction.

An electrical terminal includes a base, a first elastic arm and a second elastic arm formed side by side by extending upwardly from an upper end of the base, and a protruding portion. The first elastic arm has a mating portion, and the second elastic arm has a contact portion. The protruding portion protrudes and extends from a first side of the first elastic arm, and the first side of the first elastic arm is adjacent to the second elastic arm. A lower surface of the protruding portion has a contact surface overlapping with the contact portion in a vertical direction, such that the contact portion upwardly abuts the contact surface. When the chip module presses downwardly on the electrical terminal, the contact portion can move on the contact surface, such that the chip module does not need to press downwardly on the contact portion with a relatively large pressure.

According to a certain embodiment, a pin plunger includes: a first contact member; a second contact member that faces the first contact member and is apart from the first contact member; a spring arranged between the first contact member and the second contact member; and a housing that houses the first contact member, the second contact member, and the spring. The housing comprises a bimetal inside or outside the housing. The bimetal comprises a first metal and a second metal, the first metal having a thermal expansion coefficient different from a thermal expansion coefficient of the second metal. The elastic force decreased or increased by contracting or expanding of the spring due to a temperature change is compensated with a warping force due to stretching of the first metal and the second metal.

A printed circuit board, including: a contact point for contacting; a contact spring for an electrical contact in a vehicle; in which the contact point has a support element of tin that is reflow soldered to the printed circuit board. Also described are a related module and method.

A game control device includes a housing, a circuit board, a joystick control module, and a limiting frame. The housing includes a shell plate, a through hole, and an internal accommodation space. The through hole is defined through the shell plate along an axial direction and in communication with the internal accommodation space. The circuit board is disposed in the internal accommodation space. The joystick control module includes a joystick and a motion sensor. The motion sensor is disposed in the internal accommodation space and electrically connected to the circuit board. One end of the joystick is detachably connected to the motion sensor, the other end of the joystick protrudes out of the shell plate, and the joystick is within the through hole. The limiting frame is disposed on the shell plate and detachably connected to the through hole to limit a movement of the joystick along the axial direction.

A redriver chip comprising: pre-stage transmission pin sets, pre-stage reception pin sets, post-stage transmission pin sets, post-stage reception pin sets and selectors. The pre-stage transmission pin sets and the pre-stage reception pin sets are disposed in alternating arrangement, and the post-stage transmission pin sets and the post-stage reception pin sets are disposed in alternating arrangement. The amount of the post-stage transmission pin sets is an integral multiple of the amount of pre-stage reception pin sets, and the amount of the pre-stage reception pin sets is an integral multiple of the pre-stage transmission pin sets. Each of the selectors is connected to one of the pre-stage reception pin sets and integral multiple amount of the post-stage transmission pin sets, or is connected to one of the pre-stage transmission pin sets and integral multiple amount of the post-stage reception pin sets.

An electrical ground connector for use as part of a test connector in an integrated circuit (IC) device testing apparatus having a resilient connector for electrical grounding and comprising a dual elastomer contact stacked vertically above a rigid ground block. The height of the ground block can be adjusted to compensate for the lack of height of the dual elastomer contacts, so that the entire connector has enough height to maintain electrical connection between a load board of the testing apparatus and the IC device.

A socket electrically connects a first electric component and a second electric component, including: a base part in which a through hole extending through the base part from a top surface to a bottom surface in a vertical direction is formed; a contact pin inserted to the through hole such that a pin lower end is exposed from the bottom surface, and configured such that, when in use, a pin upper end makes contact with the first electric component; and a sheet member including a through electrode extending therethrough in the vertical direction, disposed at the base part in a state where the sheet member faces the bottom surface, and configured such that, when in use, an upper end of the through electrode makes contact with the pin lower end and a lower end of the through electrode makes contact with the second electric component.

A detachable capacitor connection structure is provided for a storage device. In an embodiment, a connection element detachably connects a capacitor module including one or more capacitors to a circuit board such that the capacitor module is stacked over the circuit board. The connection element includes: a first connector including two pin headers, mounted on a bottom plane of the capacitor module; and a second connector including two sockets, mounted on a top plane of the circuit board corresponding to the bottom of the capacitor module, suitable for connecting the first connector to the circuit board.
