Description

Circuit board bearing device

The utility model is about a kind of circuit board bearing device, refers to that especially a kind of circuit board bearing frame snaps in the circuit board bearing device that assembles in the casing of electronic apparatus with two sections.

The tradition Computer system case includes pedestal, loam cake and panel, is used for encapsulation such as computer subsystems such as disc driver, CD drive and motherboards.Pedestal comprises base plate, flat board, header board and back plate, and framework normally is square.Base interior also is provided with magnet stand, power supply support and motherboard carrier etc., and wherein the motherboard carrier is to be fixedly arranged on pedestal one side, constitutes the square box body with an opening with pedestal.On assembling flow path, this tradition Computer system case is that said elements is fitted together one by one, and then acquires the computer subsystem step by step in housing.But this single assembling flow path can make assembly line long and be difficult to the management, when a certain link of assembly line goes wrong, whole production line is stopped.Especially when the assembling motherboard, because the restriction of shell space kenel brings greater inconvenience to practical operation.Moreover, computer competition in the industry fierceness now, the computer price constantly descends, and the computer member is on the increase, producer has the simplification assembling flow path only, improves packaging technology, shortens to assemble and just can force down high speed development and the low price wind transmission tide of production cost to adapt to computer man-hour, and is to be one of packaging technology emphasis in the computer casing of how motherboard fast being packed into reliably.

For this reason, some removable formula motherboard carriers are employed, and its installation and the mode that removes are varied, no matter but any mode all exists bigger defective.As No. the 84201628th, Taiwan patent application, the motherboard carrier of its announcement be with the dismounting of Spring lock catch mode on computer chassis, but the complex structure of this Spring lock catch device, element is a lot of, it is limited not only to reach effect, also increases the manufacturing cost of product simultaneously.

No. the 84214655th, the Taiwan patent application for another example, the motherboard carrier of its announcement be with pallet from bottom to top buckling device on computer chassis, this carrier one side is provided with first lug to be fastened on first caulking groove of casing, the carrier opposite side then is provided with second lug, be installed with into the shell fragment of V font on this lug, when snapping in first caulking groove by first lug, shell fragment is fastened on casing and carrier is fixed.Though this kind carrier is simple in structure, assembling easily, but V font shell fragment elasticity after using several times can reduce widely, make the retain strength between carrier and casing occur loosening phenomenon inadequately, thereby firm inadequately, and from the bottom to top pallet is packed into, comparatively difficult for the assembler application of force, the Assembly Action smoothness that can't link up, really can't realistic production line on the requirement of assembling fast.

And for example No. the 85200273rd, the Taiwan patent application, motherboard carrier four edges of its announcement are provided with bent sheet, following bent sheet can be inserted in the corresponding fixed rail of chassis backplane location and can be along the fixed rail slippage, between the retaining edge that last bent sheet then can be resisted against casing top diaphragm plate is dashed forward with plate, prominent corresponding to this plate, last bent sheet is provided with depressed part, allows depressed part align plate bent sheet is inserted between retaining edge and plate dash forward.By this carrier of slippage backward, the retaining edge is dashed forward and carrier can be fixed with plate.But clearly can be owing to manufacturing tolerance etc. between the prominent and bent sheet of shelves edge, plate former thereby have the gap, carrier also can move on fore-and-aft direction thereby be firm inadequately.

And for example No. the 86209311st, the Taiwan patent application, and it has disclosed and a kind ofly directly with slide rail motherboard has been installed in mode on the casing.This mode is that slide rail is set on motherboard, and the chute of being made up of lug then is set on casing, and slide rail slides in the groove and the assembling motherboard.But this kind mode can only be applied in the specific motherboard and casing structure, and can not adapt to the change of motherboard or casing structure, does not have flexibility.

The purpose of this utility model provides a kind of circuit board bearing device that can pack into fast and securely in the case of electronic device, and this device being by protruding peritreme and cooperatively interacting of chute and slidable fit, and the buckle that passes through shell fragment is fixed.

The purpose of this utility model is achieved through the following technical solutions: the utility model circuit board bearing device comprises carrier, is divided into the shell fragment of the upper and lower slide rail of magnet stand and chassis backplane and several and the affixed one of upper and lower slide rail.Wherein slide rail respectively is provided with flat part, and flat part is then established chute, and chute divides and is set as guide channel road and main channel and forms " L " shape.Carrier is equipped with respectively and flat part and corresponding bent plate of chute and protruding peritreme in upper limb and lower edge, with slidable fit and locate this carrier.This carrier is provided with trip in addition, and shell fragment then is provided with hole clipping, but is snapped in this carrier of hole clipping fixing by trip.

By technique scheme, the assembling of the utility model circuit board bearing device and case of electronic device is quick and firm, thereby saves man-hour, reduces cost.
