Coil spring contact type connector

Abstract

A coil spring contact connector (C) includes a plurality of coil spring contacts (1) and an insulating holder (2) holding the coil spring contacts arranged at intervals. Each coil spring contact has a pair of end contact coils (10) to be brought into contact with a terminal electrode (6c), and middle contact coils (12) radially offset relative to the end contact coils (10) so as to be brought into contact with another terminal electrode (5c). The holder is provided with openings through which contact parts of the end and the middle contact coils project outside, respectively, restrains each coil spring contact (1) from axial deformation and axial movement, and allows each coil spring contact (1) to be deformed in an offset direction thereof.

Description

technical field

[0001] The present invention relates to a coil spring contact connector for connecting spring coils by being interposed between two parts and a circuit substrate for electrically connecting the connecting electrodes of the two parts. Background technique

[0002] Hitherto, as a connector for electrically connecting the connection electrodes of two components and a circuit board by being interposed between them, an elastic connector composed of conductive rubber contacts contained in a case has been used. However, in such elastic connectors, there is a disadvantage that it is difficult to obtain stable contact because the conductive rubber contacts are deformed and exposed outside the case.

[0003] Therefore, connectors for connecting spring coils instead of conductive rubber contacts have been proposed. This coil spring contact connector (patent 10-12777 published in 10 years of Japanese Heisei) is as Figure 12 with 13 shown.
