A connector includes a housing which allows for insertion and fitting into a mating connector in an insertion direction perpendicular to a height direction and to a width direction, and a regular fitting detecting member. The regular fitting detecting member is supported on an outer wall surface of the housing so as to be slidable in the insertion direction to a non-detection position and a detection position. The regular fitting detecting member includes a base portion which has a detecting portion which allows for detecting regular fitting at the detection position, and an elastic piece and a pair of guide pieces which extend in the insertion direction from the base portion. The guide pieces allow for guiding sliding of the regular fitting detecting member by engagement with the housing. The elastic piece allows for the regular fitting detecting member to move to the detection position by being elastically deformed in the width direction. A lower surface of the elastic piece and lower surfaces of the guide pieces are disposed in a manner that shifts the position in the height direction.

A waterproof connector includes a contact, a housing, a seal member, and a cover member. An inserted portion of the housing is inserted in an insertion hole of a wall portion of a device case. The inserted portion includes an annular surface disposed flush to or with a step provided with respect to a surface of the wall portion. The seal member includes an annular first seal portion, fitted in an annular groove formed in the annular surface, and a covering portion, extending orthogonally from the first seal portion toward the surface side of the wall portion. The covering portion spanningly covers a first gap, which is a gap between an outer peripheral surface of the inserted portion and an inner peripheral surface of the insertion hole. The cover member is fixed to the wall portion across the covering portion. A second seal portion, providing sealing between the cover member and the surface of the wall portion, is formed by a portion of the covering portion that is sandwiched by the cover member and the front surface of the wall portion.

An imaging device of the present invention includes: a first case having an opening; a substrate on which a first terminal electrically connected to an imaging element is mounted, the substrate being provided in the first case; a second case covering the opening of the first case; and a connector. A first terminal accommodation portion accommodating the first terminal is fixed to the substrate. The connector includes a second terminal accommodation portion accommodating a second terminal electrically connected to the first terminal. The second case has a through hole. The first and second terminals are configured so that, in a process in which the first terminal accommodation portion and the second terminal accommodation portion are inserted to be accommodated in the through hole, the first and second terminals come into contact with each other while sliding on each other and the first and second terminals are elastically deformable upon contact with each other.

Imaging device

An imaging device includes: a first case having an opening; a substrate where a first terminal electrically connected with an imaging element is mounted, the substrate being provided in the first case; and a second case closing the opening. The second case includes an accommodation portion accommodating a second terminal designed to be electrically connected with the first terminal. A mating portion capable of being mated with the accommodation portion is secured to the substrate. Inside the mating portion, the first terminal extends along a mating direction of the accommodation portion and the mating portion. The first and second terminals are designed to come into contact with each other while sliding along the mating direction in a mating process of the accommodation portion and the mating portion, and to be elastically deformable in a first direction orthogonal to the mating direction upon contact with each other in the mating process.

A male connector includes a housing fixed to a base, a holding unit supported in such a manner as to enable displacement with respect to the housing; and an elastically deformable male terminal held by the holding unit. The housing is able to maintain the holding unit in a stationary state with the terminal undeformed and apart from the conductive film, while the holding unit is in the temporal locking position with the housing fixed to the base. The housing is able to maintain the holding unit in a stationary state with the terminal elastically deformed and contacting the conductive film, while the holding unit is in the non-temporal locking position with the housing fixed to the base.

In a memory diagnostic method, a fixed domain stores data that are not changed during process execution. A variable domain stores data that are subject to writing during process execution. A fixed domain diagnostic part adds an error-detecting code to data to be stored in the fixed domain. The fixed domain diagnostic part compares an error-detecting code calculated from data read from the fixed domain with the added error-detecting code to determine whether there is any data error. A variable domain diagnostic part temporarily stores data stored in the variable domain in a memory region different from the memory storing the data, and writes known data in the variable domain where the temporarily stored data were stored. The variable domain diagnostic part reads data from the region where the known data were written and determines whether the data is the same as the written known data.
