Abstract:
An electrical connector includes an insulative housing having a top surface, a bottom surface opposite to the top surface and a number of receiving holes penetrated the top surface and the bottom surface, a number of terminals receiving in the receiving holes and a number of solder balls assembled to the receiving holes from a bottom surface thereof and contacting with the corresponding terminals. The receiving hole includes an inner wall and a core, the inner wall has a pair of ribs extending toward to the core and the movement of the solder ball in a vertical direction is limited by the pair of ribs in a vertical direction and the solder ball is positioned by the terminal.
Abstract:
A socket connector mounted on a mother board includes a socket body with a plurality of contacts received therein, a load plate rotatable with respect to the socket body and capable of being located in a closed position above the socket body, a load lever engaged with the load plate to lock the load plate in the closed position, and a locking member. The load lever has a fastened portion engaged with locking member. The locking member has a supporting portion below the fastened portion for preventing the load lever from touching the mother board and a latching portion above the fastened portion for preventing the load lever from upwardly escaping away from the locking member.
Abstract:
An electrical contact (20) for using in a CPU (central processing unit) socket, includes a planar base portion (201), a pair of flexible arms (203) extending from the planar base portion, a pair of contact portions (204) being orthogonal to the flexible arms, a pair of stopper portions (205) coplanarly formed on the flexible arms and a solder portion (206) being orthogonal to the planar base portion and extending parallel to the contact portions.
Abstract:
An electrical connector includes a base having a number of passageways and a compartment in one end thereof. A cover is mounted to the base. The cover has a plurality of through holes corresponding to the passageways and a driving compartment corresponding to the compartment. The driving compartment has one single-step stopper. One recess is positioned adjacent the stopper and receives a stiffener therein for supporting the stopper. A cam is disposed in the driving compartment and the compartment to drive the cover moving relative to the base along a front-to-back direction.
Abstract:
An electrical connector assembly according to a preferred embodiment includes an electrical connector (1) and a pick up device (5) engageably mounted onto the electrical connector. The electrical connector includes a rear head portion, where an actuator (4) is rotatably held therein, and a front tail portion opposite to the head portion. The pick up device has a front covering portion (58) extending in a forward and downward direction relative to the front tail portion. Thus, during a SMT process used for soldering the electrical connector to a printed circuit board, temperature in difference is prevented between the head portion and the tail portion due to their different heat absorption characteristic, thereby avoiding solder wicking and/or bridging of the tail portion.

Abstract:
An electrical connector having a fusible element for mounting on a substrate includes an insulative housing and a contact terminal retained in the insulative housing. The contact terminal includes a resilient contacting arm extending beyond a mating face of the insulative housing and a soldering portion for mating with the fusible element. A gelatinous flux is deployed on the fusible element, and/or on the soldering portion, and/or between the fusible element and the soldering portion, and then flux is dried to immovably fix the fusible element with respect to the soldering portion. The dried flux will be re-juvenile to clean and remove an oxidized layer originally existed on the soldering portion so as to achieve robust welding quality. Besides, a method for trimming an electrical connector to have robust welding properties is also disclosed.
Abstract:
A contact sheet (100) comprises a first contact strip (1), a second contact strip (4) coplanar with the first contact strip (1) and a plurality of first contacts (2) and second contacts (3) located between the first contact strip (1) and the second contact strip (4) alternatively, the first contact (2) comprises a first body portion (21) having a first notch (211) and a first protruding portion (212), the second contact (3) comprises a second body portion (31) having a second notch (311) and a second protruding portion (312), the first protruding portion (212) fits with the second notch (311), the second protruding portion (312) fits with the first notch (211).

Abstract:
An electrical connector comprises an insulative housing (2), a plurality contacts (4) received therein, at least a pair of securing members (3) disposed on adjacent corners of housing (2). The securing members (3) are used for supporting a chip module and able to slide in an upright direction, which can solve the balance problem produced in process of mounting a heat sink.
