ABSTRACT:
A test adapter is provided for connection to a PLCC (Plastic Leaded Clip Carrier), hereinafter referred to as a carrier, which assures accurate alignment with the carrier, which can be locked to the carrier during a test, which has a width only slightly greater than that of the carrier to enable testing of closely mounted carriers, and which can be simply constructed. The adapter includes an inner housing that bears against the top of the carrier and four contact frames pivotally mounted on the housing and carrying contacts that engage leads of the carrier. Each contact frame has separators between the contacts, the separators passing between the leads of the carrier to directly engage the sides of the carrier housing. The lower surface portions of the separators are slightly angled from the vertical so when they press against angled surfaces on the carrier housing sides, the adapter is locked to the carrier. The contact frames are held to the housing to pivot thereon by a snap ring that extends around the four frames and is supported by the frames.
