Patent ID: 7738255

Claim:
An electronic module comprising: a board unit including a board attachment portion on which a circuit board is mounted, and a panel portion to which a handle is attached; and a module housing to which the board unit is removably attached, wherein the handle includes a grip portion, and a pair of leg portions extending from both ends of the grip portion, a length of the handle in a longitudinal direction of the handle is shorter than that of the panel portion in the longitudinal direction, the pair of leg portions is supported by a pair of support members fixed to the panel portion so that the pair of leg portions is rotatable in a direction along which the grip portion is brought into contact with and is separated from the panel portion, the support members are fixed to the panel portion at an interval which is shorter than the length of the panel portion in the longitudinal direction of the handle, the pair of leg portions has engagement convex portions that extend from portions, serving as rotary pivots, of the leg portions toward a side opposite to the grip portion, and protrudes from one side of the board attachment portion on which the circuit board is not provided, the module housing includes, in a port portion through which the circuit board is taken in and out, engagement concave portions that are provided so as to correspond to the engagement convex portions and that extend along the longitudinal direction of the handle, when the board unit is inserted into the module housing, by rotating the handle around the rotary pivots in a direction along which the grip portion approaches the panel portion, the engagement convex portions are brought into contact with a part of the engagement concave portion to produce a force in a direction, along which the board unit is pressed into the module housing; and when the board unit is extracted from the module housing, by rotating the handle around the rotary pivots in a direction along which the grip portion is separated from the panel portion, the engagement convex portions are brought into contact with another portion of the engagement concave portion to produce a force in a direction, along which the board unit is extracted from the module housing.
