Description
Technical field
The present invention relates to a kind of structure that is connected and fixed of circuit board, and particularly relevant for a kind of plug-in card fixing structure.
Background technology
Please refer to Fig. 1, Fig. 2, it illustrates the known fixed structure that is used for fixing long and short card respectively.Along with the consumer is more and more higher with microminiaturized requirement to product function, electronic product is many to be its development trend to have miniaturization and multifunction concurrently.For this reason, manufacturer develops that required circuit layout is integrated in modularized design and electronic building brick forms electronic cards or printed circuit board (PCB), to save the space and to be beneficial to installation.With Fig. 1, Fig. 2 is example, and stub 110a wherein and long card 110b are exactly modular electronic cards.Stub 110a is identical with the long card bayonet connector 104 that 110b connected.Yet, because stub 110a blocks the different of 110b length with length, just need be on the substrate in diverse location boring with the installing support column.For example, stub 110a utilizes support column 106a and screw 108 to be fixed on the substrate 102; Long card 110b utilizes support column 106b screw 108 to be fixed on the substrate 102.Because support column 106a is different with support column 106b position, need be on the substrate 102 in diverse location boring with the installing support column.If support column 106a and support column 106b are contained on the substrate 102 simultaneously so that fixedly stub 110a and length are blocked 110b (being illustrated as Fig. 3), when the long card of installing 110b, the installing of the long card of support column 106a meeting overslaugh 110b, and drilling hole amount increases on circuit board, understands the wiring area of compressor circuit plate relatively.Above-mentioned all inconvenience makes manufacturer that the demand of improvement plug-in card fixing structure be arranged.
Summary of the invention
Therefore purpose of the present invention is exactly that a kind of plug-in card fixing structure of improvement is being provided.
According to above-mentioned purpose of the present invention, a kind of plug-in card fixing structure is proposed, it comprises a substrate, a bayonet connector and a bracing frame.Bayonet connector is positioned on the substrate, is connected with it for the direction of a plug-in card with the almost parallel substrate.Bracing frame has a base plate, biside plate and two fixtures.Base plate is fitted and is fixed on the substrate.Biside plate stretches out from the both sides of base plate.Two fixtures are positioned at the top margin of each side plate, wherein base plate be selectivity be fixed on the substrate a plurality of positions one of them, make one side that two fixtures are not connected with bayonet connector in order to fixing plug-in card.This fixed structure can reduce the drilling hole amount of substrate, increases the wiring area of circuit board relatively; And can promote the stability of plug-in card.

Embodiment
Please refer to Fig. 4, Fig. 5, it illustrates the plug-in card fixing structure according to a preferred embodiment of the present invention.Plug-in card fixing structure 200 comprises a substrate 202 (for example printed circuit board (PCB)), bayonet connector 204 and bracing frame 206.Fig. 4, Fig. 5 illustrate two kinds of fixed forms of bracing frame 206 respectively, make screw hole 206c on the bracing frame 206 apart from bayonet connector 204 differences (both directions are opposite), and then the fixing plug-in card of different length.
Only boring on the substrate 202 under the situation of a pair of screw hole, bracing frame 206 just can utilize screw 208 to lock in two ways on the substrate 202, and makes virtual online (with reference to the dotted line among Fig. 4, Fig. 5) between the 206c of two-screw hole be parallel to the fillet 204a of bayonet connector 204.
With reference to Fig. 4, Fig. 6, virtual online when nearer between the 206c of two-screw hole apart from bayonet connector 204, bracing frame 206 just can utilize screw 208 to lock one side that stub 210a is not connected with bayonet connector 204.Stub 210a utilizes another side to be plugged on the fillet 204a of bayonet connector 204 with the direction of almost parallel substrate 202.
With reference to Fig. 5, Fig. 7, virtual online when far away between the 206c of two-screw hole apart from bayonet connector 204, bracing frame 206 just can utilize screw 208 to lock one side that the long 210b of card is not connected with bayonet connector 204.Long card 210b utilizes another side to be plugged on the fillet 204a of bayonet connector 204 with the direction of almost parallel substrate 202.
The mode that bracing frame 206 is fixed in substrate 202 is not restricted to above-mentioned mode.With reference to Fig. 8, bracing frame 206 can only bore a lockhole, utilizes a screw 208 to be attached on the substrate 202 in the screw hole.Bracing frame 206 the same can being fixed on the substrate 202 according to Fig. 4 and Fig. 6 dual mode.In addition, with reference to Fig. 9, the lockhole 206d on the bracing frame 206 can be a strip, the convenient distance of adjusting between bracing frame 206 and the bayonet connector 204.The long axis direction of lockhole 206d is approximately perpendicular to virtual online (with reference to the dotted line among the figure) between the 206c of two-screw hole.When between the 206c of two-screw hole during the virtual online fillet 204a that is parallel to bayonet connector 204, bracing frame 206 can prolong direction 220 (direction of vertical fillet 204a) and adjust the distance between bracing frame 206 and the bayonet connector 204.Therefore, the plug-in card length range that can fix of bracing frame 206 can widen.Bracing frame 206 the same can being fixed on the substrate 202 according to Fig. 4 and Fig. 6 dual mode.
In addition, the fixture on the bracing frame 206 also is not restricted to above-mentioned screw hole.Please refer to Figure 10, the fixture on the bracing frame 206 is that a trip 206e is in order in the lockhole that snaps in plug-in card.The connecting portion of trip 206e and side plate 206b has pliability, makes things convenient for plug-in card to be fixed on the bracing frame 206 or dismounting on the self-supporting frame 206.
By the invention described above preferred embodiment as can be known, use plug-in card fixing structure of the present invention, manufacturer just can utilize the design of above-mentioned bracing frame, adjusts the distance between bracing frame and the bayonet connector, with the fixing plug-in card of different length.
Though the present invention discloses as above with a preferred embodiment; right its is not in order to limiting the present invention, anyly is familiar with this technical staff, without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention should be as the criterion with the content that claim was defined.
