Claims

[Scope of Claim for Utility Model Registration] It has a package connector fixed to a package board on which various parts are mounted, and a back connector mounted on a back wiring board provided on the back of a unit on which the package board is mounted in a bookshelf format. It is a guide pin of a plug-in connector that connects the package board and the back wiring board by fitting the package connector and the back connector. In the structure of the guide pin, which is inserted into the guide pin alignment hole of the package connector and guides when the package connector and the back side connector are mated, the guide pin has a narrow diameter part in the middle separated by steps at both ends, and also serves as a guide for the back side wiring board. A guide pin that passes through a guide pin hole with a diameter larger than the outside diameter of the pin, and is fitted into the narrow diameter portion on the opposite side of the back wiring board from the back connector, and is shaped like an umbrella in the axial direction of the guide pin. A guide pin structure for a plug-in connector, characterized in that it has a locking piece that expands and a cut-and-raise spring that holds the back connector floating on the back wiring board via the guide pin.
