Further, a method for installing a flexible, resilient lid to a container, the container comprising a base portion having a side support at each side of the container and an end support at each end of the base portion, the method including bending the lid by applying pressure to each end of the lid; aligning the lid with each end support; and releasing the lid, wherein the lid re-forms into a flat lid within the end supports.

A medical device, comprising a housing, a combined modular structure which is formed by connecting a board card and an interface panel to a main bracket; a first opening arranged on the housing for the insertion of the combined modular structure; a first locking structure for locking and fixing the combined modular structure to the housing; a screen assembly; a second opening arranged on the housing for mounting the screen assembly, and a second locking structure for locking and fixing the screen assembly to the housing. The integral arrangement of a functional module of a medical device helps to improve the assembly precision between various components, and ensure the reliability of the connection between components. The housing adopts an integral structure, has good waterproof and dustproof effects as well as low production costs; the present disclosure facilitates the assembly of board card and other components, as well as module configuration and modular testing while also having good seismic performance.

A housing for an electronic circuit comprises tub-shaped lower and upper parts and a rectangular printed circuit board, PCB. The lower part comprises PCB supports and molded position fixing formations on opposite inner walls and first parts of latching apparatuses, for connecting to the upper part, on opposite outer walls. The formations positionally fix the PCB by engaging into matching fixing slots therein. The PCB has, in each corner, a slot-parallel to the inner walls with the supporting elements forming elongate, resilient tabs, the length of the slots greater than the spacing of the respective slot from the adjacent PCB edge. The upper part comprises pins protruding out of the plane of the edge and pressing the resilient tabs out of the PCB plane into the lower part, with the housing assembled, and, on opposite outer walls, second parts of the latching apparatus for connecting to the lower part.

An electronic device is provided. The electronic device includes: a panel, a first support component, and a second support component. The panel includes a bottom surface, a first corner and a second corner, and the bottom surface is connected between the first corner and the second corner. The first support component includes a first side portion that supports the first corner of the panel. The first side portion has a first length and a first Young's modulus. The second support component includes a second side portion that supports the second corner of the panel. The second side portion has a second length and a second Young's modulus. The first length and the second length satisfy the following inequalities: $10\times \sqrt{\frac{W}{2k1\times \tan 1^{°}}}\le L1<\frac{P}{2},\mathrm{and}$

A cold worked stainless steel bezel for a portable electronic device is provided. The bezel is secured flush to a housing to form part of the case of the portable electronic device. A brace that includes a slot for receiving a wall extending from the bezel is fixed to the housing. When the bezel engages the housing, the wall of the bezel is inserted in the slot of the brace and releasably held by a spring that engages both the brace and the wall. The bezel can be released by disengaging the spring, (e.g., using a special tool or a magnetic field). Because the bezel is manufactured from cold worked stainless steel, it is hard and resistant to impacts. Cold worked steel also facilitates manufacturing within design constraints and tolerances, and requires very little machining after manufacturing to comply with those constraints.

An electrical device includes a container, a conversion unit, an outer cover and an inner cover. The container is provided with an inner bottom surface and an inner which define an accommodating channel together. An inlet of the accommodating channel is opposite to the inner bottom surface. The conversion unit is disposed within the accommodating channel. The outer cover covers the inlet of the accommodating channel. The inner cover is disposed within the accommodating channel, and located between the conversion unit and the outer cover. One part of the conversion unit extends to the opening, and at least one outer edge of the inner cover is connected to an inner wall of the container.

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.
