The present disclosure discloses a socket connector including an insulating base and a number of socket terminals. The insulating base includes an outer plastic frame defining a receiving channel and an inner plastic block received in the receiving channel. The inner plastic block includes two sidewalls opposite to each other in a left-and-right direction. The socket terminals are arranged in two rows by positioning symmetrically and respectively on the two sidewalls of the inner plastic block. The socket terminals of each row are arranged in an upper-and-lower direction and spaced away from each other in the upper-and-lower direction. Each socket terminal extends along a front-and-back direction perpendicular to both the left-and-right direction and the upper-and-lower direction. A connector assembly including the socket connector and the mated plug connector is also disclosed in the present disclosure.

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.

An electrical connector includes: an insulating body provided with multiple accommodating holes running vertically therethrough, and multiple terminals correspondingly accommodated in the accommodating holes. Each accommodating hole has two protruding portions. Each terminal includes a main body portion. Two upper elastic arms are formed by bending upward and extending from left and right sides of the main body portion. Each upper elastic arm extends backward to form an upper abutting portion. A strip connecting portion extends upward from the main body portion to be connected to a strip. The strip connecting portion is located between the two upper elastic arms. Each of the left and right sides of the main body portion is provided with a position limiting portion protruding outward. The position limiting portion is located below the protruding portion. The position limiting portion and a corresponding upper elastic arm overlap along a vertical direction.

An electrical contact for use with an electrical connector includes a conducting part and a supporting part wherein the conducting part has the better conduction characteristic than the supporting part while the supporting part has the better resiliency/strength characteristic than the conduction part. The conducting part includes a main body, an upper contacting arm extending upwardly from the main body and a lower contacting arm extending downwardly from the main body. The supporting part includes a secondary body, an upper supporting arm upwardly extending from the secondary body and a lower supporting arm downwardly extend from the secondary body. The main body and the secondary body are engaged together securely. The end of the upper contacting arm and that of the upper supporting arm are coupled together and the end of the lower contacting arm and that of the lower supporting arm are coupled together.

An electrical connector includes multiple conductive terminals respectively retained in multiple accommodating slots of an insulating body. Each conductive terminal includes a base portion, a connecting portion extending from one side of the base portion, a first elastic arm and a second elastic arm extending from the connecting portion toward a direction away from the same one side of the base portion, and at least one fixing portion extending from another side of the base portion. A width of the connecting portion is less than a width of the base portion and less than a width of a location of the first elastic arm near the connecting portion as well as a width of a location of the second elastic arm near the connecting portion. The fixing portion and the first elastic arm are respectively located at different sides of the base portion, thus achieving good elasticity and thinness.

An interposer includes a housing having a plurality of through-holes penetrating a first surface and a second surface and a signal contact pair composed of a pair of signal contacts. Each of the signal contacts includes a base portion press-fitted in one of the through-holes, a first contact beam extending from the base portion beyond the first surface, and a second contact beam extending from the base portion beyond the second surface. The pair of signal contacts are positioned adjacently to each other widthwise and are each asymmetrical with respect to a width direction. A first minimum spacing between the first contact beams of the pair of signal contacts is narrower than a second minimum spacing between the base portions of the pair of signal contacts. The signal contact pair has a plane-symmetrical shape with respect to the width direction.

A connector includes: a housing; and a detector detecting whether a terminal is received at a regular position. The locking portion has an abutment part to lock the terminal, and an interference part interfering with the detector to prevent the detector from being assembled to the housing. The abutment part is displaced to lock the terminal at the regular position when the terminal is at the regular position, and to leave the terminal when the terminal is not at the regular position. The interference part moves along with the abutment part to a position not to interfere with the detector when the terminal is at the regular position, and to be displaced to a position to interfere with the detector when terminal is not at the regular position.

A terminal unit assembly in which a plurality of terminal units extending in a longitudinal direction are arranged in a lateral direction orthogonal to the longitudinal direction, and a frame member including an assembly accommodating recess for accommodating the terminal unit assembly; wherein the terminal unit includes a longitudinally extending terminal holding part, a main body held by the terminal holding part, a plurality of terminals including contact parts protruding above the top face or below the bottom face of the terminal unit and contact arms connecting the main body to the contact parts, and a housing wall extending in the longitudinal direction; and the terminal holding part includes a plurality of laterally protruding protrusions, and at least one of the protrusions abuts against a housing wall of an adjacent terminal unit.

An electrical contact includes a main body, a supporting arm extending upwardly from an upper edge thereof, and a spring arm extending curvedly and upwardly from a lower edge thereof with a contacting region at a free end. The spring arm will contact the supporting arm when the spring arm is downwardly pressed by the CPU. A solder part is sidewardly connected to a downward extension formed on a lower portion of the main body and located beside the spring arm, and includes a vertical section extending from the side edge of the downward extension, a horizontal solder pad extending from a lower edge of the vertical direction wherein a curved joint is formed between the downward extension and the vertical section for easy adjusting the angle formed between the downward extension and the vertical section, thus being adapted to fit different CPUs and PCBs.

An interposer assembly having a housing with contact positioning holes each having a first wall face and a second wall face. The interposer contact has a base portion with shoulder portions and contact arm portions. The base portion is closer to the first wall face. The contact arm portions are once bulged from both respective vertical ends of the base portion toward the first wall face and then curved toward the second wall face. The housing has a retaining protrusion and a pair of slit portions. The retaining protrusion retains the interposer contact inside the contact positioning hole. Each of the shoulder portions is inserted into the slit portion. The slit portion blocks the interposer contact from moving toward the second wall face.
