[Prior art]
In recent years, studies on technologies for connecting wiring bodies such as electric wires, cables, and circuit boards, or between wiring bodies and electrical devices have progressed (in this specification, wiring bodies and electrical devices to be connected are described below. "Connected body"). In particular, when there are a large number of connection points in the connection body, a technique for collectively connecting these connection parts, for example, a technique using a connector is required, and the technology has been actively studied.
[0003]
A relay card edge connector for connecting printed boards (circuit boards) is known as an example of a technique that uses a connector for connecting connectors. The relay card edge connector is for connecting the first printed board and the second printed board so that they can be inserted and removed, for example, the second printed board for converting the arrangement of the conductive pattern and the relay printed board. Used in combination with a card edge connector to eliminate the need to change the pattern of the first printed board (see Patent Document 1).
