Problems solved by technology

If you want to use an inexpensive connector that does not have a guide function, since it does not have a guide function, there is a fear that the printed circuit boards will not be connected correctly due to deviation of the insertion position or wrong insertion (reverse insertion), and it will be difficult to connect the connector. Plugging and unplugging, connector damage, etc.

Abstract

The invention is to provide a printed board connecting strucuture, wherein printed boards can be connected together properly, even when using an inexpensive connector that is not provided with a guiding function. A motherboard (1) comprises a guiding hole (1a); and a child board (2) comprises a guiding protrusion (2a). When connecting the motherboard (1) and the child board (2), the guiding protrusion (2a) of the child board (2) engages into the guiding hole (1a) of the motherboard (1), and a first connector (3-1) (one of male connectors (3)) and a second connector (3-2) (one of female connectors (3)) are mated together with the engagement of the guiding hole (1a) and the guiding protrusion (2a) as guidance.

Description

technical field [0001] The present invention relates to a connection structure for connecting printed circuit boards to each other through fitting of connectors. Background technique [0002] Conventionally, connection between printed circuit boards has been performed by fitting connectors. That is, the connection between the printed circuit boards is performed by fitting one of the male and female connectors with the other. The connector used for the connection between the printed circuit boards has not only the function of connecting signal lines but also the function of guiding for normal fitting (for example, refer to Patent Document 1). Also, some connectors have a sequencing function (a function of determining the contact order of ground terminals, power terminals, signal terminals, etc.) in addition to the guiding function (for example, refer to Patent Document 2).
