A connector assembly includes a first connector having a first fitting detection terminal and a second connector having a second fitting detection terminal, when a fitting operation starts, a pressing portion of a second housing of the second housing makes contact with a pressed portion of a spring portion of the first fitting detection terminal to cause an elastic deformation of a spring body, whereby the second connector advances without making contact a second contact point of the second connector with a first contact point of the first connector, and when the fitting operation is completed, the pressing portion passes the pressed portion of the spring portion to release the elastic deformation of the spring body, whereby the second contact point makes contact with the first contact point, and the second fitting detection terminal is electrically connected to the first fitting detection terminal.

A connector includes a first insulator having a first support surface, a second insulator having a second support surface, a contact member held by the second insulator and having a contact portion exposed at the second support surface, and a hold mechanism holding the contact portion toward the first support surface, the first insulator having a first through hole penetrating the first insulator from the first support surface to a bottom surface of the first insulator at a position corresponding to the contact portion, the hold mechanism having a boss passing through the first through hole to a bottom surface side of the first insulator and holding the contact portion toward the first support surface by use of the boss.

A sample preparation method and device for preparing a vitrified sample layer (1) on a sample holder grid (3) for subsequent analysis of physical sample characteristics, particularly for subsequent cryo electron microscopy, are presented. The method comprises:providing the sample holder grid (3) with sample solution (5) on at least one surface of the sample holder grid (3);- spreading the dispensed sample solution (5) along the surface (7) of the sample holder grid (3) using one or a sequence of multiple shock pressure waves (9) being generated by a shock pressure wave generator (11) emitting and directing the one or multiple shock pressure waves (9) via at least one nozzle (13) onto the surface (7) of the sample holder grid (3);- vitrifying the spread sample solution (5) by exposing it to a cooling liquid (17) at cryogenic temperatures.
