The housing includes a first recess extending in a first direction within a horizontal plane, opening downward, and having at least a rear side inner facing surface and a plurality of slits extending in a second direction intersecting the first direction within the horizontal plane at intervals in tg downward, and having at least a rear side inner facing surface and a plurality of slits extending in a second direction intersecting the first direction within the horizontal plane at intervals in the first direction. The terminals are disposed in the housing so as to extend from inside the first recess to inside the slits and electrically connect a conductive portion provided on a board to thehe first direction. The terminals are disposed in the housing so as to extend from inside the first recess to inside the slits and electrically connect a conductive portion provided on a board to theelectrode of a device under test. The needle holder is disposed in the first recess. The rear side inner facing surface of the first recess includes a slope sloping with respect to both the horizontalelectrode of a device under test. The needle holder is disposed in the first recess. The rear side inner facing surface of the first recess includes a slope sloping with respect to both the horizontal plane and a vertical plane perpendicular to the horizontal plane so as to extend forward as it extends upward. Each terminal abuts on the slope at at least a part of its rear end. Thus, sliding of thplane and a vertical plane perpendicular to the horizontal plane so as to extend forward as it extends upward. Each terminal abuts on the slope at at least a part of its rear end. Thus, sliding of the terminals with respect to the conductive portion is reduced.e terminals with respect to the conductive portion is reduced.

Description

technical field [0001] The present invention relates to an electrical connection device used in the energization test of a planar object to be inspected such as an integrated circuit, and more particularly to an electrical connection device for electrically connecting a conductive part formed on a substrate and an electrode of the object to be inspected. device. Background technique [0002] In a semiconductor device such as an integrated circuit, a plurality of electrodes protrude from the body of the device. Such a semiconductor device is subjected to an energization test (inspection) using an electrical connection device called a socket. As one type of such an electrical connection device, there is an electrical connection device described in Patent Document 1, for example. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2003-123874 [0004] Such as Figure 7A , Figure 7B as well as Figure 7C As shown, the electrical connection device described in Patent ...
