Problems solved by technology

[0014] However, in a non-contact connector, when it is desired to arrange the electrodes on two substrates at a high density to increase the number of transmission channels, since the above-mentioned mutual distance needs to be set very narrow, only This is difficult to achieve in manufacturing due to mechanical precision
In addition, in the miniaturized non-contact connector, there is no structure that can reliably maintain the above-mentioned mutual distance at a predetermined value with a simple structure.

Embodiment Construction

[0037] Figure 2A The basic structure of an example of the non-contact connector of the present invention is shown together with a wiring board. for having Figure 2A The capacitive coupling-type non-contact connector of the shown basic configuration may be configured as a board-to-board connector for electrically connecting opposing wiring boards, for example, as will be described later.

[0038] exist Figure 2A Here, the wiring board may be, for example, the transmission-side wiring board 10B or the receiving-side wiring board 10A. The reception-side wiring board 10A and the transmission-side wiring board 10B having a predetermined waveform shaping circuit have the same configuration as each other except for a transmission chip and a reception chip to be described later. Therefore, the basic configuration of the reception-side wiring board 10A having the reception unit portion 12A will be described, and the description of the transmission-side wiring board 10B will be om...

Abstract

Disclosed is a non-contact connector which restricts the gap between an electrode pad (18bi) and another electrode pad (30ai) to a predetermined value using protruding sections (18BD) after a reception unit section and a transmission unit section are brought close to each other. The upper end surfaces of the protruding sections (18BD) abut the surface of a reception side wiring board (30A) under a predetermined pressure caused by the elastic force of a flexible wiring board (18B).

Description

technical field [0001] The present invention relates to a non-contact connector applicable to electrostatic capacitive coupling and electromagnetic induction coupling. Background technique [0002] In data transmission / reception sections of a pair of memory cards connected to each other, for example, as shown in Patent Document 1, a non-contact connector of a so-called electromagnetic induction coupling method has been proposed. In addition, this memory card is inserted into a writing / reading device, for example. [0003] In each memory card, the non-contact connector includes, for example, a writing control coil and a reading control coil, a plurality of writing coils and a plurality of reading coils, and the plurality of writing coils and multiple Two reading coils are alternately formed in a straight line along the end of the memory card. [0004] The write coil in one memory card and the read coil in the other memory card are arranged to face each other, and electromag...
