The first and second connector alignment pins and the first and second alignment openings can each include tapered portions to move the connector assembly into alignment with the connector aperture as the cover is attached with the housing.

An enclosure assembly for housing printed circuit boards and related electrical components having a secured faceplate that may be removed by use of a hand tool.

A frame includes a first frame, a back case and a second frame. The first frame includes a first frame plate and a first frame wall, the back case includes a back case plate and a back case wall, the second frame includes a second frame plate and a second frame wall, and the second frame surrounds the first frame and the back case. The second frame plate is located on a side of the first frame plate facing away from the back case plate, and the first frame wall is protruded from a surface of the first frame plate facing towards the back case plate, the back case wall is protruded from a surface of the back case plate facing towards the first frame plate, and the second frame wall is protruded from a surface of the second frame plate facing towards the first frame plate.

According to one embodiment, a connection device includes an engaging claw extending in a first direction from a first member, and a receiving portion provided in a second member. The engaging claw includes a pair of first side surfaces, and a pair of engaging protrusions projecting out from the respective side surface. Each engaging protrusion includes an inclined surface continuous from the first side surface and inclined to the first direction. The receiving portion includes a pair of slopes extending in the first direction and each including a second side surface engaging the first side surface, and an engaging projection connected to the second side surface, the engaging projection engaging the engaging protrusion.

Disclosed are an electronic signboard and a wall hanging device. The electronic signboard includes a display device and a wall hanging device. The display device is provided with a first fitting portion, and the wall hanging device is provided with a second fitting portion detachably connected to the first fitting portion. The wall hanging device is further provided a fixing surface via which the wall hanging device is fixed to a mounting base.

A device casing is configured to include a first casing member provided with a hole including a guide hole and a fitting hole that communicates with the guide hole, and a second casing member provided with a protrusion at a position corresponding to the hole, the second casing member being configured to be fixed with respect to the first casing member by fitting the protrusion to the fitting hole. The guide hole guides movement of the protrusion that entered within the guide hole in an oblique direction when fixing the second casing member with respect to the first casing member so that the second casing member can get close to the first casing member in a state where the second casing member is guided in the oblique direction. The protrusion that moved in the oblique direction along the guide hole, passed through the guide hole and reached inside the fitting hole fits to the fitting hole. The second casing member is fixed with respect to the first casing member by the fitting of the protrusion to the fitting hole.

An electronics device includes a housing having a through-hole disposed in a central portion of the housing. A printed circuit board is connected to the housing.
