An electrical connector for a compressor of an HVAC system includes electrical leads and a plug communicatively coupled to the electrical leads. The plug includes a plug body and first connectors configured to electrically couple the electrical leads to second connectors of the compressor via engagement of the first connectors with the second connectors. The first connectors are symmetrically distributed on the plug body such that the first connectors can align with the second connectors in a plurality of alignment orientations of the first connectors and the second connectors. The plug also includes at least one interference projection radially extending from a periphery of the plug body. The at least one interference projection is configured to physically interfere with a positioning guide of the compressor and block engagement between the first connectors and the second connectors in all except for one alignment orientation of the plurality of alignment orientations.

A socket connector device for mating with a central processing unit having conductive portions is provided. The socket connector device includes a circuit module, a terminal module, and a cover plate. The terminal module is placed on the circuit module. The terminal module includes a terminal block. The terminal module includes a terminal block, multiple rows of terminals integrally formed with the terminal block, and a support housing protecting the terminal block. Each terminal includes a first contact end and a second contact end corresponding to each other. The second contact end protrudes from the support housing. Each first contact end electrically contacts one conductive portion, and each second contact end electrically contacts the circuit module. The cover plate is rotatably assembled on the terminal module, so that the conductive portions of the central processing unit electrically contact or do not contact the terminals of the terminal block.

A multi-platform modular device including a plurality of platforms or modules. Each module implements a different function and can be connected to another module via a plurality of magnetic contacts. The magnetic contacts can be used for synchronization, communication, and power delivery between the modules.

An implantable medical device includes a cover assembly and a feedthrough assembly that couples with the cover assembly. The cover assembly receives a connector end of a lead having lead contacts, and aligns the lead contacts with pockets or apertures of the cover assembly. The feedthrough assembly may include feedthrough contacts in the form of feedthrough pins at or above a surface of a feedthrough substrate, or conductive vias on the surface of the substrate. Electrical contacts configured as leaf spring contact assemblies, torsion spring contacts, or torsion spring contact assemblies are permanently attached to the feedthrough contacts. When the cover assembly and feedthrough assembly are coupled, contact tabs of the electrical contacts are positioned in the pockets or apertures of the cover assembly. Upon complete seating of the cover assembly and feedthrough assembly, the contact tabs are compressed into contact with the lead contacts.

A magnetic connector assembly has a female connector with spring-loaded conductive pins slightly protruding inside a recess or cavity in the female connector's body. A corresponding male connector has a protrusion on its body with conductive pins slightly indented into the protrusion's surface. The protrusion on the male connector is sized and shaped to fit into the cavity in the female connector such that the male connector's pins engage the pins of the female connector, allowing for electrical communication across the connector assembly. Magnets on the male and female connectors secure them in a correct orientation. A unique shape ensures proper alignment of the pins and prevents the connection of incompatible devices.

An electrical connection unit for a battery pack includes a busbar having a first hole therein, a top surface and a bottom surface, an annular bushing having a top end abutting the bottom surface, a bottom end opposed to the top end and a bore hole therein registered with the first hole, a busbar cage secured to the busbar and retaining the annular bushing in abutment with the busbar, the busbar cage having a cavity therein above the top surface, and a fastener having a head portion captured within the cavity and a shank portion extending through the first hole. The annular bushing may include one or more indents formed on an outer surface thereof, and the busbar cage may include a plurality of fingers extending along the outer surface and interfacing with the one or more indents. Each finger may include a protrusion configured to rest within an indent.

A clamping assembly for attaching a grounding conductor to a pipe having a protective coating includes an elongate conductive strap and a clamp. The conductive strap is sufficiently long to circumferentially surround the pipe and has longitudinally spaced sharp projections that are sufficient to penetrate the protective coating around the pipe to make an electrical coupling between the strap and a conductive part of the pipe beneath the protective coating. The clamp is coupled to the grounding conductor and clamps the conductive strap to the pipe at a tension sufficient to maintain an electrical connection between the conductive part of the pipe and the grounding conductor without the need for any welding of the grounding conductor to the pipe and without the need for any stripping of the protective coating from the pipe.

A plug connector for connecting to a complementarily formed counter plug connector, having an inner conductor which is supplied with high current, and an outer conductor that surrounds the inner conductor and has an outer contact element on a front side of the plug connector for the purposes of shield transfer where the outer contact element is designed for shield transfer, being in the form of a rigid ring element having a mating surface, surrounding same in a peripheral direction, for surface mating with a complementarily formed counter mating surface of the counter plug connector, which mating surface runs transversely in relation to an insertion direction (S) of the plug connector.
