Abstract: A computer housing includes: a housing body; a first supporting plate mounted in the housing body; a second supporting plate mounted in the housing body and cooperating with the first supporting plate to define a mounting space therebetween; and an operating lever pivoted to the second supporting plate, formed with an engaging tongue, and rotatable relative to the second supporting plate between a first angular position, in which the engaging tongue extends into the mounting space for retaining a box-like device in the mounting space, and a second angular position, in which the engaging tongue is disposed outside of the mounting space for permitting removal of the box-like device.

Abstract: A computer housing includes: a housing body having a front wall formed with a front opening and a mounting frame that defines a frame space and that has two opposite side walls, each of which is formed with two engaging holes and an engaging notch; and a faceplate having two engaging units, each of which includes a pair of first engaging arms and a second engaging arm. Each of the first engaging arms extends into a respective one of the engaging holes. The second engaging arm has a hook end in snap engagement with the engaging notch.

Abstract: A test socket for an integrated circuit includes a frame body, a number of electrical contacts, two sliding plates, a mechanism for slidingly moving the sliding plates in a horizontal direction, and two elastic elements. When applying a force to the mechanism, the sliding plates slide away from each other to make each ball contact of a ball grid array integrated circuit move downwardly into an associated through-hole of the sliding plate. When the force is removed, returning forces provided by the elastic elements return the sliding plates to their close contact status, and each ball contact is born against by an associated electrical contact and thus retained in the associated through-hole of the sliding plate such that signals from the ball contacts can be outputted via the electrical contacts.
