A connector includes a fixed housing, a movable housing, and multiple contacts. Each of the fixed housing and the movable housing is formed of an insulator. The contacts are formed of a conductor. Each of the contacts has a first end fixed to the fixed housing and a second end fixed to the movable housing to displaceably connect the movable housing to the fixed housing. The movable housing includes a protrusion positioned between the contacts.

An electrical connector includes: an insulating body; multiple terminals, each terminal having a contact portion and at least one clamping portion forming a clamping space; and multiple solder posts, each being correspondingly placed in the clamping space. The solder post has a foundation post and a protruding portion extending upward from the foundation post. The clamping portion clamps the foundation post in the clamping space. A width of the protruding portion is smaller than a width of the foundation post. The foundation post is cylindrical. A height of the solder post is greater than a diameter of the foundation post. The solder posts are arranged more densely on the insulating body. When the electrical connector and a circuit board are together placed into a reflow oven, hot gas flows around the protruding portion more easily, and a contact area between the hot gas and the protruding portion is larger.

To be capable of easily avoiding lengthening and heightening with a simple configuration even in a case where relatively large electric power is supplied.

Provided is a configuration in which the conductor resistance of a plurality of contact members 13 and 14 is reduced in accordance with an increment in thickness and energization allowable electric power is increased by one of more of the contact members 13 and 14 being formed thicker than the rest so that an increase in the size of an electric connector such as lengthening and heightening is prevented even in a case where the supply electric power with respect to the electric connector is large and the retention of a flat plate-shaped signal transmission medium F is enhanced by contact portions of the thickness-increased contact members 13 and 14 being pressure-welded to the flat plate-shaped signal transmission medium F.

An electrical connector for a glazing comprising a connector portion for connection to an electrical supply, and a button for soldering to a surface of the glazing, the button comprising a base portion adjacent, in use, to the surface of the glazing and an upper portion remote, in use, from the surface of the glazing, wherein the button comprises at least one solder-contacting surface, at least a portion of the solder-contacting surface curving from the base portion to the upper portion and defining a tapering solder cavity. A glazing comprising the electrical connector is also disclosed as is a method of soldering the electrical connector to a glazing.

A die-packaging component includes a substrate, a die, a jumper structure, a lead structure and a package body. The substrate has a base surface further including a die-connecting portion and a package-body retaining structure surrounding the die-connecting portion. The die connects the die-connecting portion. The jumper structure welded to the die generates a thermal deformation while in conducting a high-voltage current. The lead structure includes a lead groove defining a thermal-deformation tolerance allowable route. While in meeting the thermal deformation, the jumper structure welded to the lead groove as well is movable along the thermal-deformation tolerance allowable route. The package body at least partly covers the lead structure and the substrate, completely covers the die and the jumper structure, and is constrained by the package-body retaining structure.

An improved transition between a central contact of a coaxial component and a transmission line, such as a radio-frequency transmission line, is provided. The transition may be between a central contact of a coaxial component and a transmission line of a circuit such as a radio-frequency circuit. The central contact has a cylindrical front portion and, extending its front portion, a rear portion that makes contact with the transmission line and that is fastened thereto by a solder joint. The rear portion has at least one gap, defining a volume forming a reserve for the solder of the solder joint.

A strain relief for a coaxial cable and coaxial connector interconnection is provided as an injection moldable polymer material surrounding the interconnection. The injection moldable material fills a solder pre-form cavity between an outer conductor of the coaxial cable and an inner diameter of a bore of the connector body, strengthening and environmentally sealing the interconnection. Where the outer conductor is corrugated, the polymer material may be provided covering an exposed portion of the corrugations and/or filling portions of a corrugation trough between an outer jacket and the outer diameter of the outer conductor.

A card edge connector forms a plurality of passageways in the elongated housing to receive the corresponding contacts. Each contact has a retaining section secured to the housing, a resilient arm extending from an upper part of the retaining section with a contacting section exposed in the central slot, a soldering section extending from a lower part of the retaining section and out of the housing. A width of the passageway around the contacting section in the longitudinal direction is smaller than that around the soldering section.

A connector lead has a lead terminal that includes a recessed solder wicking restriction area for ensuring that enough solder remains on or near the lead terminal. The lead terminal has a neck portion and a base portion extending from the neck portion. The neck portion has a width that is narrower than the width of the lead. The narrower neck portion defines a recessed solder wicking restriction area that encourages more solder to accumulate on or near the base portion instead of wicking up the lead. The width of the neck portion may also be narrower than the width of the base portion, causing the lead terminal to resemble an inverted T when viewed from the front. A band of solder resistive material may be applied circumferentially or laterally around the connector lead above the lead terminal to limit wicking in some embodiments.

In examples of the present disclosure, a vented electrical terminal block may include a body that may be configured to support a plurality of electrical terminals In examples, the body may include a plurality of side walls that may extend from the body. The body may include a plurality of apertures extending through the body. A cavity may be defined by an underside of the body. The cavity may receive a cavity fluid. In examples, at least one side wall may include an opening for receiving a sealing fluid, and apertures may be configured to vent said cavity fluid from the cavity when sealing fluid is introduced into the cavity via the opening.
