Abstract: The present invention relates to a low-thermal resistance pressing device for a socket, which mainly comprises a housing, an inner collar, a heat conductive pressing block, a bearing collar and a locking member. The locking member on the housing is used to lock the socket. The inner collar is threadedly engaged with the housing. The bearing collar is located between the inner collar and the heat conductive pressing block. In the case of rotating the inner collar in the housing, the bearing collar drives the heat conductive pressing block to move axially so as to exert an axial force to a device to be tested. Because the heat conductive pressing block protrudes from the upper and lower surfaces of the housing, one end thereof can be in contact with a temperature control module, and the other end thereof can be in contact with the device to be tested.

Abstract: 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.
