A connecting element includes a support member, a flexible substrate wrapped around the support member, and elastic contacts provided on the flexible substrate. A positioning hole is formed in the support member. A first positioning component is positioned and soldered on a metal layer formed on a motherboard, and a second positioning component is positioned and soldered on a metal layer formed on an electronic component. The first positioning component is inserted into the positioning hole in the connecting element, and the second positioning member is fitted to the first positioning component. Accordingly, the connecting element is positioned with respect to both the motherboard and the electronic component.

Connecting element and circuit connecting device using the connecting element

A substrate is formed with a plurality of spiral contactors on an upper surface serving as a first surface and a plurality of connecting terminals on a lower surface serving as a second surface. Since the spiral contactors are arranged in a matrix on the upper surface serving as the first surface, a lot of spiral contactors can be provided on the substrate of the present invention, and a mount area can be enlarged, and the size of the connector can be decreased.

Substrate having spiral contactors

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.

Spiral contactor, contact sheet having spiral contactor, and connecting device having contact sheet

An IC card connector is provided with grounding terminal members, in which a pair of grounding terminal members has simple structure and common shape allowing a reduced cost and easy fabrication. The IC card connector is provided with a housing with a plurality of pin terminals, a frame mounted on the housing, a pair of guide sections are provided longitudinally at both side sections of the frame to remove and insert to IC card, and respective arm sections of grounding pieces. mounted on the guide sections. The IC card is inserted between the guide sections so that a grounding terminal of one side section of the IC card is made to come into contact with first expanded sections, while a grounding terminal of the other side section of the IC card is made to come into contact with second expanded sections.
