In an embodiment, a socket comprises a housing, where the housing is a dielectric material. In an embodiment, a shell passes through a thickness of the, where the shell is conductive. The socket may further comprise a plug within the shell, where the plug is a dielectric material, and where the plug has a bottom surface. In an embodiment, a pin passes through the thickness of the housing within an inner diameter of the shell, where the pin has a first portion with a first diameter and a second portion with a second diameter, and where the pin is conductive. In an embodiment, the socket further comprises a spring around the first portion of the pin, where a first end of the spring presses against the bottom surface, and where a second end of the spring presses against the second portion of the pin.

The present invention relates to a chip-fixing device for a socket, which comprises a fixing base body and a movable stop. The socket is assembled in a socket-accommodating recess of the fixing base body. The movable stop is assembled in the fixing base body and controlled in such a manner that a stopper is moved between a first position and a second position, wherein the first position refers to a position where the stopper is located right above the socket, and the second position refers to a position where the stopper is not located right above the socket. Accordingly, the socket-accommodating recess can be used to install sockets of different sizes, and the movable stop can drive the stopper to restrict a chip from falling off the socket or drive the stopper to release the chip, depending on presence or absence of an external force.

The present disclosure sets forth a rigid, self-aligning radio frequency (“RF”) connector comprising a rigid body with a first connection end and a second connection end opposite the first connection end. The RF connector can also comprise a recess disposed on an outer surface of the rigid body between the first and second connection ends, and a collapsible connector support that can comprise a connection portion and a collapsible portion. The collapsible connector support can be disposed within and protrude from the recess while also being configured to collapse into the recess. The collapsible connector support can also be configured to interface with an interfacing surface to facilitate generation of a reaction force sufficient to support the RF connector in an offset position relative to the interfacing surface and to nominally align the RF connector with a device to be connected.

The present disclosure provides to a lamp socket structure. The lamp socket structure includes a plastic outer housing, a metal inner housing, an insulating bottom plate, a live-wire metal connecting piece, and a neutral-wire metal connecting piece, wherein the metal inner housing is in a cylindric structure, a receiving chamber configured to receive a lamp cap is disposed inside the metal inner housing, a positioning chamber having a small upper portion and a large lower portion vertically runs through a top portion of the metal inner housing, the live-wire metal connecting piece is plugged into the two matting columns, a riveting head is integrally and protrusively fixed to both a top portion of the live-wire metal connecting piece and a top portion of the neutral-wire metal connecting piece, the riveting head being in a U-shaped plate structure; and the metal inner housing, the insulating bottom plate, the live-wire metal connecting piece, and the neutral-wire metal connecting piece constitute a conducting base for conduction of the lamp cap, the plastic outer housing being mounted to the conducting base by an injection molding process. The lamp socket structure is reasonable in design, and may prevent poor contacts at a wire junction due to high temperature at the lamp cap when the wire is mounted. Therefore, this lamp socket structure is suitable to promotion and application.

A connection system to facilitate the mechanical coupling, and the transfer of electrical power between, trunk sections of an artificial tree is disclosed. The connection system can include a mechanical coupling system having a guiding surface and a guiding slot on a first trunk section and a guiding protrusion disposed inside a second trunk section. Insertion of the first trunk section into the second trunk section and thus contact of the guiding protrusion against the guiding surface can cause the first trunk section to rotate relative the second trunk section until a predetermined rotational alignment is reached, aligning electrical contacts of first and second electrical connectors, each of which is attached to an outer wall of a respective trunk section. The electrical contacts of the first and second electrical connectors can establish electrical communication between the first and second electrical connectors, and thus between the first and second trunk sections.

A radio frequency (RF) electrical contact includes an electrical contact having a stationary electrical contact member and a movable electrical contact member that is received by the stationary electrical contact member. The movable electrical contact member is movable between an initial position and a mated position. The movable electrical contact member can contact the stationary electrical contact member at a stationary or fixed contact location.

A terminal is to be connected to a mating terminal having a flat surface portion. The terminal includes a conductive main body having an abutment surface, an annular terminal spring, the annular terminal spring being held on the abutment surface and a fastener holding the annular terminal spring on the abutment surface. The fastener includes a main body shaft being inserted into a central space of the annular terminal spring, a first end of the main body shaft being fixed to the conductive main body, and a plurality of arm portions extending outward in a radial direction of the fastener from a second end of the main body shaft, the second end being opposite to the first end, the plurality of arm portions being configured to hold the annular terminal spring at a contacting portion of the annular terminal spring, the contacting portion contacting the abutment surface.

An electrical connector includes an electrical connector housing having a body with a receiving portion, a movable pin, a part of the movable pin is movably disposed in the receiving portion, a first elastic piece disposed in the receiving portion, and a second elastic piece located between a side wall of the receiving portion and the movable pin and elastically abutted against an outer circumferential surface of the movable pin. A first end of the movable pin movably protrudes out of the receiving portion against an elasticity of the first elastic piece. The movable pin is electrically connected to the electrical connector housing by the first elastic piece and the second elastic piece.

The present invention relates to a board mating connector including a first body part having a first hollow portion formed therein, a signal contact part inserted into the first hollow portion, a dielectric part positioned between the first body part and the signal contact part, a second body part which has a second hollow portion formed therein, is positioned between the dielectric part and the first body part, and is formed of a metal plate, and a ground contact part which extends upward from an upper side of the second body part and is separated into a plurality of portions by a plurality of slits to have elasticity.

A retractable pin includes: a cylindrical body, a retractable member with an insertion cavity at one end, and a spring disposed in a spring cavity defined by the combination of the retractable member and the cylindrical body. Upon application of a force to a free end of the retractable member, the retractable member is configured to retract into the cylindrical body by means of compression of the spring. This invention is further directed to a coaxial connector including a retractable pin as described above.
