Embodiment Construction

[0038] figure 1 It is a plan view showing the screw contact as the first embodiment of the present invention, figure 2 yes figure 1 A sectional view of the 2-2 line.

[0039] figure 1 The illustrated screw contact 10 has a support portion 11 and a deformation portion 12 formed in a spiral shape. The deformation portion 12 has a winding start portion 12a on the outer peripheral side, and a winding end portion 12b on the center and inner peripheral side of the scroll. The supporting part 11 is provided on the outer peripheral side of the deforming part 12 , and the winding start end part 12 a of the deforming part 12 is a structure extending continuously from the supporting part 11 . In addition, the front end of the winding end portion 12b is formed in a large area, and is provided as a butting portion 12c for contacting the center of the external contact of the electronic component.

Abstract

This invention provided a spiral contact capable of improving a mounting density per unit area, and also having large spring constant, and a contact sheet or the like equipped therewith. A supporting portion is provided only at a winding start portion side and an outside of the other part of a deforming portion other than the winding start portion side is opened. Thus, adjacent spiral contactors can be arranged to be close to each other. Therefore, a mounting density of a spiral contactor on a guide frame can be increased. Further, since the deforming portion can be arranged at an opened region, a width of the deforming portion can be widened. As a result, the spiral contactor having a large spring constant is provided.

Description

technical field [0001] The present invention relates to a screw contact electrically connected to an electronic component having a connecting terminal such as BGA or LGA, in particular to a screw contact capable of increasing the spring constant and at the same time increasing the assembly density per unit area, and a contact with the screw contact sheet and a connecting device with said contact sheet. Background technique [0002] Figure 7 is a plan view showing part of a contact piece having a conventional screw contact, Figure 8 It is an enlarged plan view of a conventional screw contact. [0003] Figure 7 The illustrated contact strip 1 has a guide frame 2 made of an insulating sheet, on which a plurality of screw contacts 3 are regularly arranged longitudinally and transversely. like Figure 8 As shown, each screw contact 3 is formed of a substantially square thin copper plate or the like, and has a support portion 3A functioning as an outer frame and a deformed p...
