A socket (,) includes a body (,) and a cover (,). Body (,) has a base (,) having a horizontally movable slide (,) thereon on which a BGA package can be mounted and a plurality of contact members (,) arranged on base (,) corresponding to a pattern of solder balls of the BGA package. Each of contact members (,) has a pair of spring arms (,) which can be opened and closed in response to movement of slide (,). In one embodiment, a cover (,) is vertically movable relative to body (,). The cover (,) has motion transfer portions (,) having a wedge shape which are engageable with tapered force receiving portions (,) of slide(,). As cover (,) is pushed down, engagement surfaces (,) of motion transfer portions (,) engage force receiving surfaces (,) of slide (,) and slide (,) moves so that arms (,) of contact members (,) are opened. In another embodiment, the motion transfer parts (,) are provided on a head (,) which has an air suction holder for a BGA package.

Electrical socket apparatus

This invention relates to a fuel heating device for internal combustion engines, in which both fuel heating means and fuel conductance passage are accommodated in the main body, constructed in such a manner that the fuel is injected after being heated while it passes the aforementioned fuel conductive passage to be arranged proximate to the combustion chamber of the internal combustion engine.

Fuel heater for internal combustion engines

A thermally and electrically conductive housing having a solid tip portion is shown mounting a heating element thermally and electrically coupled to the tip portion which in turn is electrically coupled to a switch mechanism mounted within the housing. The switch mechanism includes a thermostatic snap acting disc adapted to bias a movable electrical contact away from a stationary electrical contact at preselected temperatures. The housing is shown mounted in a carburetor of an automobile to contact energization of a honeycomb heater disposed in the carburetor, however; the device can be used in other locations where it is desired to maintain a body within a selected temperature range.
