The specific embodiment
Like Fig. 1, shown in 2, the utility model comprises box body 1, framework 2, transverse slider 3 and spacer 4.Through adjustable spacer 4 is set in box body 1, makes in the device and can put a plurality of size different circuits.Through height and the pin length according to circuit card on spacer 4 positive stop lug boss 8 is set, the position of permanent circuit has also protected the circuit card pin not receive touching to distortion on the other hand better on the one hand.The utility model is easy and simple to handle, and cost of manufacture reduces greatly, only need open a mould to multiple circuit and process, even by the job operation of very high degree of precision, your single circuit inner packing cost also only has about ten yuan.Increase with order quantity, cost is also lower.
Box body 1 is for square and have nowel 5 and loam cake 6, and nowel 5 can be closed and locked with loam cake 6, and according to the minimum altitude requirement of intraware, the inner chamber height of box body 1 should be greater than 25mm; Consider traffic cost, box body 1 should be selected the plastics of lighter weight for use.
Framework 2 is embedded in around nowel 5 inboards, and framework 2 is that 2020 matrix type aluminium section bar is formed by code name, because on this kind aluminium section bar groove is arranged, is convenient to install slide block.Be cut into two kinds of size section to above-mentioned model aluminium section bar through machinework, as the long limit 15 and broadside 16 of framework 2, be assembled into four frames with four standard straight angle connectors 14 that match with aluminium section bar respectively, right-angle connector 14 is connected through screw with aluminium section bar.Specification is this kind aluminium section bar of 202mm * 125mm, and maximum can be put 2 in the circuit of the outer length of side of 60mm * 60mm, and minimum can be put 8 in the circuit of the outer length of side of 12mm * 12mm.
As shown in Figure 3, transverse slider 3 is a gauge member, and there is tapped bore inside, and it is connected through screw with spacer 4.The big I of slide block is selected according to the groove size of aluminium section bar.
As shown in Figure 4, spacer 4 is positioned at framework 2 upper surfaces and there is connecting bore 7 at two ends, and connecting bore 7 is positioned on the groove of framework 2 length directions, the tapped bore of transverse slider 3 be positioned at said connecting bore 7 under.
As shown in Figure 5; Spacer 4 is selected antistatic material for use, and the positive stop lug boss 8 of two integrated moldings is arranged on the spacer 4, and positive stop lug boss 8 is made up of horizontal stand 9 and two vertical bars 10 of square; Horizontal stand 9 width a are 1.5mm; Can reduce the area of contact of circuit bottom surface and packing, prevent that the bottom surface from having heat sink or during cover plate, cause the friction of large tracts of land Gold plated Layer.Two vertical bar 10 grades are high, are used for the horizontal degree of freedom of restricting circuits plate, and vertically the height of bar 10 is confirmed according to the vertical dimension of pin.The angle of the horizontal stand 9 of two squares relatively but do not contact otherwise can cause scratch mutually between the circuit card on the same spacer 4.
As shown in Figure 6, the structure of all spacers 4 is all identical with installation direction, and two spacers 4 share the package main body that can clamp a circuit.Spacer 4 drives transverse slider 3 and on groove, slides, and confirms the spacing between the spacer 4 according to the package main body size; After spacer 4 spacings were confirmed, spacer 4 was fixedly connected on the framework 2 with transverse slider 3.
As shown in Figure 1, framework 2 has longitudinal sliding block 11 in the groove of Width, in the longitudinal sliding block 11 tapped bore is arranged, and the annexation of longitudinal sliding block 11 and groove is same as the relation of transverse slider 3 and groove.After all spacers 4 are fixedly connected on the framework 2; The longitudinal screw slide block is through screw 12 and framework 2 detachable static connections; Purpose is for the height that utilizes screw 12 to exceed aluminium section bar limits the degree of freedom of aluminium section bar in box body 1 short transverse, prevents in transit, and the loam cake 6 of circuit and box body 1 clashes into; So after nowel 5 and loam cake 6 closures, the inside face of loam cake 6 just in time contacts the head of said screw.
As shown in Figure 7; Method in adopting Fig. 1 limits the box body 1 short transverse degree of freedom, can also take the method for elasticity joint strip 13, pastes two elasticity joint strips 13 at the inside face of the loam cake 6 of box body 1; The position that as far as possible makes joint strip is at the edge of loam cake 6, so as not to the extruding circuit.As shown in Figure 3, guarantee elasticity joint strip 13 thickness with the height of assembly height h with than the big 1mm-2mm of box body 1 inner chamber height, neither transition extruding circuit card can satisfy the requirement of restraint of liberty degree again.
The content of not doing to describe in detail in the specification sheets of the present invention belongs to those skilled in the art's known technology.
