An electronics circuit card system includes a flexible elongated hollow receptacle; a working fluid disposed within the flexible elongated hollow receptacle; one or more wicking structures formed within an interior hollow region of the flexible elongated hollow receptacle, wherein the one or more wicking structures are configured to circulate the working fluid within the flexible elongated hollow receptacle and expand the flexible elongated hollow receptacle against an electronics circuit card; and a chassis configured to hold the flexible elongated hollow receptacle against the electronics circuit card.

A method of maintaining a circuit card in a card rack and a circuit card rack system are disclosed. A card rack including a laterally oriented clamping slot is provided. The clamping slot is at least partially formed from a temperature-contractible material. A circuit card having a clamped side region is provided. At least a portion of the clamped side region is inserted into the clamping slot. A predetermined temperature differential is applied to the clamping slot to reduce a longitudinal dimension of at least a portion of the clamping slot. A compressive force is exerted on the portion of the clamped side region which is located longitudinally within the clamping slot, via thermal expansion of the clamping slot.

An image apparatus includes an imaging unit, a housing that houses the imaging unit, a wiring substrate, and a stopper that sandwiches the wiring substrate between the housing and the stopper. The housing has a protruding part that protrudes from a back surface of a side opposite to a front surface on the side of the imaging unit in the wiring substrate. The stopper has an engagement part that engages with an outer peripheral surface of the housing, and a hook part that is hooked onto an inner peripheral surface of the protruding part of the housing.

A deep-water submersible system is disclosed. The system can include a pressure vessel and an internal assembly. The internal assembly can include a housing and a wedge lock assembly coupleable to the housing. The wedge lock assembly can include a plurality of wedge members arranged along a longitudinal axis and including end wedge members at each end and one or more intermediate wedge members between the end wedge members. The wedge lock assembly can also include a displacement device along the longitudinal axis and connecting the end wedge members. The displacement device can be actuatable in one direction to move the end wedge members toward one another to displace adjacent wedge members relative to one another in a direction transverse to the longitudinal axis to engage and apply a clamping force to the housing and the pressure vessel. In addition, the wedge lock assembly can include a variable gap compensation mechanism operable to exert a biasing force on the plurality of wedge members to accommodate the relative transverse movement of the adjacent wedge members and maintain the clamping force on the housing and the pressure vessel within a predetermined range as a distance between the housing and the pressure vessel varies.

The present invention relates to a fixing apparatus for fixing one or more printed circuit boards to a housing wall having a frame part that comprises at least one locking means for fixing the frame part to the housing wall and at least one wedge body displaceably supported within the frame part, wherein the wedge body is displaceable into a position relative to the frame part in which a compressive force applied to the frame part by the wedge body deforms the outer frame wall at least regionally outwardly.

A printed circuit board cooling structure is provided, where a printed circuit board (PCB) is fixed to the printed circuit board cooling structure for cooling and meeting mechanical and electrical requirements. The printed circuit board cooling structure includes a cooling case in which printed circuit boards (PCB) are cooled with air or fluid, and a cold plate structure which is placed in the case made from a slit opened in the relevant board area of the cooling case, transfers the heat to chassis (case) wall, and eliminates wedge mechanism.

A guide and support apparatus is provided. The guide and support apparatus comprises a mounting portion, a support portion, and a guide and lock portion. The support portion extends to the guide and lock portion and ends at the mounting portion. The mounting portion extends downward from one or two ends of the support portion and comprises a lock structure. The guide and lock portion extends from the support portion to a certain height. Further, a method for manufacturing the guide and support apparatus is provided.

A faceplate that is attached to a circuit board on the side of an extraction direction in which the circuit board is extracted from a slot includes: a main body that covers an opening of the slot; and two handle portions that are disposed respectively at both ends of the main body with respect to a width direction of the circuit board and that extend in the extraction direction. The two handle portions have respective distal ends shifted from each other in a thickness direction of the circuit board. Multiple slots are formed in a casing of an electronic device along a width direction thereof.

A method of maintaining a circuit card in a card rack and a circuit card rack system are disclosed. A card rack including a laterally oriented clamping slot is provided. The clamping slot is at least partially formed from a temperature-contractible material. A circuit card having a clamped side region is provided. At least a portion of the clamped side region is inserted into the clamping slot. A predetermined temperature differential is applied to the clamping slot to reduce a longitudinal dimension of at least a portion of the clamping slot. A compressive force is exerted on the portion of the clamped side region which is located longitudinally within the clamping slot, via thermal expansion of the clamping slot.

A card edge connector assembly includes a card edge connector having a housing defining a card slot configured to receive a paddle card of a pluggable module and having a mounting lug having a datum surface. The card edge connector assembly includes support hardware coupled to the housing having a base including a locating cavity having a locating surface that receives the mounting lug such that the locating surface engages the datum surface of the mounting lug to locate the support hardware relative to the housing at a support location. The support hardware has a support beam extending from the base having a support surface for supporting the pluggable module independent of the card edge connector such that the paddle card is oriented in the card slot relative to the contacts for electrical connection therewith.
