Description

Movable fixed plate is used radiating machine casing more

The utility model relates to a kind of radiating machine casing, particularly be that a kind of little complete electronic set movable fixed plate is used radiating machine casing more.

Commercially available middle-size and small-size complete electronic set all is that various elements such as each circuit board, transformer, integrated package are fixed on the casing component by screw, support etc. at present, heater element is directly installed on the heating panel of the complete machine back side or both sides.Have in recent years and adopt aluminium alloy compression casting that little complete electronic set casing and radiator are combined.Be provided with the support column of the band screw that several and casing bottom surface connect together, be used for fixing printed circuit board and power transformer, the heater element etc. of certain specific circuit architecture, casing and heating panel are integrated.But the support printed board in this radiating machine casing, the thread pillar of element can only be determined according to a certain specific products, therefore after the production of die sinking tool, just can only adapt to this a kind of product, and because the restriction on the structural manufacturing process, can only be in the bottom surface direction installation elements and printed circuit board, so casing is big, cost is high; Once product renewal, must make mould in addition; Production cycle is long, is difficult to the many usefulness of a shell, is unfavorable for the rapid update of product; When circuitry will be done less change, just be commonly used on the casing method of holing, using the swivel nut fixed printed board, the process-cycle is long, is unfavorable for large-scale production.

In view of above reason, the purpose of this utility model is to use radiating machine casing for the housing movable fixed plate little, that cost is low, can be suitable for multiple little complete electronic set needs that a kind of energy fixed series printed circuit board or heater element etc. are provided more.

Be useful on the groove (referring to Fig. 1, Fig. 4) of retaining element radially and/or printed panel on the utility model casing, how much the depending on the needs of groove quantity.

The through hole that communicates with groove is arranged on the above-mentioned casing, and groove width of rebate b is less than through-hole diameter φ (referring to Fig. 1, Fig. 3), forms bayonet socket at circular arc and channel opening exchange place, on the tapping screw on bayonet socket clamping force big and laborsaving.

The utility model can be provided with the groove of varying number and the through hole that communicates with it according to the needs of product on casing, fixedly printed circuit board or heater element or transformer etc. of left surface direction and right flank direction in the horizontal direction,, and treat that retaining element (plate, device) can both move arbitrarily along the slotted eye direction, the assembly precision height, but securing cover plate, one shell is used more, thereby satisfy the needs of multiple little electronic system product, be particularly suitable for doing the series of products of the similar internal circuit of external form, element difference, band heater element.When product improvement, do not need boring in addition, needn't change outer casing mold, can shorten the production cycle of little electronic system product such as CATV amplifier and so on.

The utility model housing is little, and cost is low.Can adopt the moulding of hot extrusion processing technology.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:

Fig. 1 is the utility model schematic perspective view

Fig. 2 is installation site figure such as printed circuit board

Fig. 3 is groove, lead to the hole site graph of a relation

Fig. 4 is for installing the casing cross sectional representation of screw-filter

Embodiment 1:

Fig. 1-Fig. 3 is embodiment 1 figure.With reference to figure 1, Fig. 3, fixedly 8 through holes 1,2,3,4,5,6,7,8 of front and rear cover plate are arranged, the groove 9,10,11,12,13,14,15,16 that communicates with 8 through holes respectively on the casing.Groove width of rebate b is less than through-hole diameter φ.Several tapping screws 17 pass upper cover plate 18 and groove 9,10 and upper cover plate 18 are fixed on the casing.Several tapping screws are through respectively on printed circuit board 19,20 and transformer 21 plates and the groove 11,12,13,14,15,16 and circuit board 19,20, transformer 21 are installed in the casing right flank respectively, on left surface and the horizontal plane.Also can other circuit board and electronic component be installed on the casing by tapping screw and groove 15,16.This has just increased packing density greatly, adjacent panels is because orthogonal, reduced bad coupling, and all grooves all are horizontal long groove shape, identical product has been reduced the positioning accuracy request of installation elements and groove, be easy to move in the horizontal direction and adjust and guarantee each interelement reasonable cooperation, the circuit board of different product has been easy to find in the suitable position of each groove suitable fixing point, make it some kinds of products of a series of simultaneous adaptation, or the circuit of identical product is changed.Wherein groove 15,16 is particularly suitable for the fixedly MHW series integrated circuit of U.S. MOROTOLA company.The utility model casing adopts the moulding of aluminum alloy heat extrusion process.

The casing of extrusion modling in the present embodiment can be truncated into one section of 1.4～2m, also can be used to the frame principal post of fabrication and installation 19 casing equipment.

Embodiment 2:

Fig. 4 is the cross sectional representation of the present embodiment 2 of installation screw-filter.After casing adopts the hot extrusion technique extrusion modling to become aluminium alloy extrusions, being truncated into pipe nipple uses, groove 22,23,24,25 on it can be fixed two vertical direction printed circuit boards, 8 through holes in outer, groove can be fixed former and later two end plates, end plates can serve as with printed circuit board, in order to constitute various little circuitries.

Claims (2)

1, movable fixed plate is used radiating machine casing more, it is characterized in that being useful on the described casing groove of retaining element radially and/or printed panel.

2, movable fixed plate as claimed in claim 1 is used radiating machine casing more, and it is characterized in that has the through hole that communicates with groove on the described casing, and groove width of rebate b is less than through-hole diameter φ.
