2. Description of the Related Art Generally, various display panels such as electric parts, such as liquid crystal display panels, electroluminescence panels, and plasma display panels, have a large number of electrode portions on a substrate. Therefore, in the manufacturing process of the display panel, the display panel before connection of the peripheral circuits such as the driving IC tabs is inspected for display defects, display quality and the like. When inspecting the display or performance of this type of display panel, an electrical component inspection socket equipped with a contact member called a display panel inspection socket for supplying driving power to the display panel is used. There is.

As an example of this type of electrical component inspection socket, a contact member formed by forming a contact pattern on a contact film is arranged on a plate, and an electrical component mounted on the contact member is provided. By sandwiching the electrode member on the substrate of the electric component and the contactor of the contact member with a clip member having a substantially U-shaped cross section, the clip member contacts the rear side of the electric component. There has been proposed a device that is slidable between a pressing position and a position where an electric component is detachably opened.

As another example of the electrical component inspection socket, an electrical component inspection socket using two plates has been proposed. This is because the two plates sandwiching the electrical component are fastened by a tightening tool so that the contact of the contact member disposed on one plate at the time of inspection and the electrode portion on the substrate of the electrical component are in a required contact. It is configured to make contact by pressure.

[0005]

However, in the above-mentioned conventional socket for inspecting electric parts, when the display panel as an electric part is inspected, the contact of the contact member faces upward, so that It is designed to be attached to the electrical component inspection socket with the display unit facing downward. When the display panel is attached to the electrical component inspection socket, the display panel's electrode part is flipped upside down (front and back). There was a problem that the inspection had to be carried out from the normal direction upward.

Further, in the conventional socket for inspecting electric parts, individually-dedicated sockets for inspecting electric parts are required in accordance with the size of the electric part and the position of the electrode portion of the electric part. When the size of the electric parts formed on the manufacturing line or the position where the electrodes are arranged changes, for example, when a large number of types of electric parts are manufactured in one manufacturing line per day, the size of the electric parts or the electrode parts The entire electrical component inspection socket must be replaced every time the installation position of the electrical component is changed, and there has been a problem that replacement of the electrical component inspection socket requires a great deal of labor and time.

That is, the conventional electrical component inspection socket has a problem that the inspection efficiency of electrical components is poor.

The present invention has been made in view of these points, and an object of the present invention is to provide an electrical component inspection socket capable of efficiently inspecting electrical components.
