A terminal includes a spine extending along a longitudinal axis from a first end to a second end and extending along a lateral axis, which is perpendicular to the longitudinal axis, from a first edge to a second edge. An attachment portion at the first end provides fixation to an electrical conductor. A contact portion extends from the second end and cantilevers over the spine such that the contact portion is spaced apart from the spine in a direction along a vertical axis which is perpendicular to both the longitudinal axis and the lateral axis. A locking tab extends from the first edge and has a locking tab attachment end which is fixed to first edge and which extends toward, and is aligned with, the contact portion in a direction parallel to the vertical axis. The locking tab also has a free end which flares outward beyond contact portion.

An electronic assembly is provided and includes a host circuit board having an upper surface and board contacts on the upper surface. The upper surface has a mounting area. The electronic assembly includes a socket connector mounted to the host circuit board at the mounting area. The socket connector includes a socket housing holding a plurality of socket contacts. Each socket contact has an upper contact portion and a lower contact portion. The lower contact portion is electrically connected to the corresponding board contact of the host circuit board. The socket contact is compressible between the upper contact portion and the lower contact portion. The socket housing includes coolant channels configured to receive coolant. The electronic assembly includes an electronic package coupled to the socket connector. The electronic package has a lower surface and package contacts on the lower surface. The package contacts are electrically connected to the upper contact portions of the socket contacts.

A connector assembly 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.

An interposer configured for connecting arrays of signal pads on parallel surfaces is described. Contacts of the interposer are configured to provide multiple conductive paths. A first conductive path extends through the body of the contact. A second conductive path is formed in parallel to the first conductive path when the contact is compressed between opposed substrates. The contact includes an intermediate portion, a rigid portion laterally extending from the intermediate portion, and a pair of compliant arms extending from the intermediate portion in opposite directions along the mating axis. When the contact is compressed, both arms touch and form an electrical connection with the rigid portion. The presence of the rigid portion allows for a reduction in the length of the beams in tall contacts.

Provided is a board-to-board radio frequency plug, including a plug body; a plurality of plug terminals and a plurality of metal spacers integrally formed in the plug body; and a shielding shell wrapping the plug body and the plurality of plug terminals. The plug body comprises: a body base; a body outer-wall formed by integrally extending upward from a periphery of the body base; an island portion formed by integrally extending upward from middle of the body base; and an insertion space formed between the body outer-wall and the island portion. The plug terminals extend on an outer periphery of the island portion, each metal spacer is provided between two adjacent ones of the plurality of plug terminals, and each metal spacers penetrates through the island portion and the insertion space in a perpendicular direction. The present disclosure further provides a board-to-board radio frequency receptacle.

An electrical connector includes: an insulative housing having a base; a center conductor secured to the insulative housing; and a metallic shell secured to the insulative housing and surrounding the center conductor, the metallic shell including a sleeve having a lower part secured to the base of the insulative housing and an upper part extending upwardly beyond the base of the insulative housing; wherein the insulative housing is insert-molded with the center conductor and the metallic shell; and the sleeve of the metallic shell is formed as a seamless structure.

A contact unit for use within a connector includes a primary piece essentially composed of an upper part and a lower part coupled with each other. The upper part includes an upper retaining section and a resilient upper contacting arm with an upper contacting section and an upper abutment section at a free end thereof. The lower part includes a lower retaining section and a resilient lower contacting arm extending downwardly with a lower contacting section and a lower abutment section at a free end thereof. A secondary piece is spaced from and opposite to the primary piece in a horizontal direction of the contacting arm, and includes an upper abutment region adapted to be abutted against by the upper abutment section of the upper contacting arm, and a lower abutment region adapted to be abutted against by the lower abutment section of the lower contacting arm.

An electrical connector includes: an insulative housing having a base; a center conductor secured to the insulative housing; and a metallic shell secured to the insulative housing and surrounding the center conductor, the metallic shell including a sleeve having a lower part secured to the base of the insulative housing and an upper part extending upwardly beyond the base of the insulative housing; wherein the upper part includes plural curvilinear flaps coplanar with the lower part of the sleeve and plural springy flaps interposed between adjacent curvilinear flaps and extending upwardly beyond the curvilinear flaps.

An electrical contact is stamped from sheet metal and includes a planar main body, a resilient upper contacting arm extending from an upper end of the main body and a resilient lower contacting arm extending from a lower end of the main body. The upper contacting arm includes an upper oblique section and an upper contacting section at a free end thereof, and the lower contacting arm includes a lower oblique section and a lower contacting section at the free end thereof. The width of the contacting arm is similar to that of the main body while the width of the contacting section is smaller than one half of that of the main body.
