摘要:
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.

Provided herewith a socket connector adapted to be mounted on a substrate having a conductive element is provided, and comprises an insulative housing, the housing having an exterior side adapted to face the substrate. A stamped contact is formed from a sheet of conductive material and is adapted to mate with a conductive component and extending substantially to the exterior side of the housing. The contact has a connection portion and wherein a substantially dried preparation of oxidation retarding and solder affinity deployed on the terminal portion before the contact assembled into the connector. The connector further includes a body of reflowable, electrically conductive material associated adjacent to the connection portion adjacent the exterior side of the housing.

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.

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.

A burn-in socket includes a base, a sliding plate mounted to the base and having a number of pin holes, a number of contacts secured to the base and an actuator mounted on the base. The contacts each comprise a base portion and a pair of arms received in the pin holes of the sliding plate. The actuator includes a frame and a number of actuating portion for driving the sliding plate to move in a transversal direction. The actuating portion has a protrusion at a top end thereof and the protrusion makes the sliding plate not only open one of the pair of arms, but also push a solder ball received in the pair of arms away from the other one of the pair of arms.
