An electrical system includes a conductor configured to carry energy from an electrical power supply, a receiver configured to output energy to an electrical component, and a connector electrically and mechanically connecting the conductor and the receiver. The connector includes a base and a head extending from the base along a longitudinal axis. The head includes a void defined therein by a radially inner surface and further includes a radially outer surface. At least a portion of the radially outer surface is curved about the longitudinal axis. The head is insertable into the receiver, and elastic deformation of the head causes the connector to press against the receiver to retain the connector and the receiver together.

Aspects of the invention include a press-fit pin for mechanically and electrically connecting to a through-hole of a substrate. The press-fit pin can include a press-fit portion configured to be deformed upon insertion into the through-hole against a plated surface of the through-hole. A surface mount technology (SMT) pad can be coupled to a first end of the press-fit portion. The SMT pad can include a conductive material. The press-fit pin can further include a trace extension coupled to the SMT pad. The trace extension can extend from the SMT pad in a direction perpendicular to the press-fit portion. The press-fit pin can include a tip portion coupled to a second end of the press-fit portion.

Photovoltaic panels may be aggregated in various ways and may be aggregated with the use of a backplane where the backplane comprises electrical connectors positioned to electrically connect the PV panels. The PV panels may have various sizes and shapes and may overlap one or more other PV panels or PV panels being aggregated.

A pin terminal includes a bar-like base material and a plating layer covering a predetermined region of the base material. A constituent material of the base material is pure copper or a copper alloy. The plating layer includes a tin-based layer made of metal containing tin. One end side of the base material includes a tip covering portion covering an entire region in a circumferential direction of the base material. The tin-based layer includes the tip covering portion. The tip covering portion includes a thin film portion and a thick film portion at positions different in the circumferential direction of the base material. The thin film portion is provided in contact with the base material. The number of whiskers present on a surface of the thin film portion is 15 or less in a square visual field having one side length of 0.35 mm.

Disclosed is a lamp with easy assembly and disassembly comprising a power socket and a lamp body. The power socket comprises a housing and a power supply assembly which is provided in the housing, the power supply assembly is connected with a power supply, the housing is provided with at least one mounting slot which is provided with a press-type locking socket and PCB probes, and the PCB probes are electrically connected with the power supply assembly, a mounting plug with an accommodating groove is provided on the lamp body, a press-type locking plug and a PCB board are provided in the mounting plug; the PCB board is electrically connected to the light source of the lamp body; when the mounting plug is inserted into the mounting slot, the push-type locking plug is inserted into the push-type locking socket and is locked.

A multiple coaxial connector includes a contact pair that is composed of a first contact and a second contact, a body that accommodates each contact, a shell that accommodates the body, a shield cover that covers a portion of the shell, and a board mounting portion. The first contact includes a first main body portion that is extended in a first direction, a first contact portion that is formed on one end of the first main body portion and is to be brought into contact with a contact of the mating multiple coaxial connector, and a first leading portion that is extended from the other end of the first main body portion in a direction that is orthogonal to the first direction and directs toward a second direction. A plurality of the contact pairs are arranged in a third direction.

A low insertion force contact terminal which has a conductor mating portion, a securing portion and a substrate mating portion. The conductor mating portion is configured to terminate a conductor therein. The securing portion is configured to secure the terminal in a terminal receiving cavity of a housing. The substrate mating portion extends from the securing portion. The substrate mating portion has at least two sections which have curved portions thereon. The at least two sections move independently, which allows the curved portions to exert a normal force on walls of through holes of a substrate to which the contact terminal is mated which is sufficient to provide a stable electrical connection while allowing for a low insertion force.
