Description

A kind of panel casing of CD player

Technical field

The utility model relates to a kind of casing of CD player and the support of internal circuit board thereof, is meant a kind of casing structure of Ultrathin DVD machine especially.

Background technology

Along with the high speed development of electronic technology, miniaturization of electronic products, ultra-thinization are inexorable trends, and this point seems especially outstanding in domestic electronic appliances.But miniaturization makes distance or the gap between the product inner components more and more littler, and assembly difficulty is increasing, and is also more and more higher to the requirement of assembling connecting piece.For CD player, adopt soft, the outward appearance style of metal decking quality with respect to plastic rubber panel, seem high-grade more, material has determined also that with job operation the structure of metal decking is relative simple simultaneously.Now the metal decking of Cai Yonging is a kind of drawing aluminium section bar, because its any cross section along its length all is identical, causes many textural elements directly to generate, and need create the needs that can satisfy assembling by follow-up machine work.Because the profile relative fixed of CD casing is rectangular parallelepiped, it is more and more littler highly to reduce the inner space, back, and button and circuit board must be installed in inside, also be necessary for movement turnover storehouse and reserve passage, these all require metal decking inside vertical reinforcing plate structure should be arranged for button, circuit board and the both sides decorative panel location and the usefulness of taking root are installed, need to machine away wherein a part again and make the usefulness step down, cause thus that manufacturing procedure is many, process is complicated and require height, cost is high, production efficiency is low, less economical.

Summary of the invention

The purpose of this utility model provides after a kind of simple in structure, one-shot forming that the following process program is few, the easy casing structure of assembling and supporting supporting structure thereof.

Designed a kind of panel casing of CD player according to above-mentioned purpose, comprise that body cross-section is the groove shape panel casing of Contraband type, the middleware interior lining panel that includes also that a button, circuit board and both sides decorative panel are installed on it and realize by draw-in groove and screw fixedlying connected with the panel casing.

Wherein, the width of groove shape panel casing end face is shorter than the width of bottom surface, and inboard close panel wall one side has been provided with the projection of position-limiting action in the bottom surface, is provided with a downward locating groove in inside top surface and protruding corresponding section.The width of end face at this moment is 2/5～2/3 of a bottom width, the position of locating groove the end face width 1/3～2/3 between.Particularly, described locating groove two cell wall one high and one low, by the cell wall height of panel wall one side, short by the cell wall of opening one side, the height of short cell wall is 2/5～3/5 of a high cell wall.The wall by a side in the groove of short cell wall pushes up one jiao of be processed to tilt domatic in groove; High cell wall is the L type, and the corner of L is the slope that parallels with short trough wall surface slope.

In addition, the section shape of the aluminium alloy lining plate that is complementary with locating groove and spacing preiection, be used to install button, circuit board and support machine case is the flagpole shape, is movingly between the upper end of flagpole and locating groove.The lower end of interior lining panel is L shape crimping, have at L the end with the bottom surface on the corresponding screw of fixing threaded hole, the L type that above this fixing threaded hole, is provided with turn left to and the frame of the power circuit board location that fuses with edge, have through hole on it with the screw coupling.Be provided with the zigzag sway brace that the xsect that stretches out is slightly deformed outside the panel casing on the top of interior lining panel, forward stretch out that support has the main frame case on the end face, the Γ type that below sway brace, also is provided with turn left to and the frame of the power circuit board location that fuses with edge, have through hole on it with the screw coupling.

The utility model has effectively been realized keeping away the position and having reduced installation procedure and subsequent reprocessing program of installation process, structure, the structure of CD player casing inside had both been simplified greatly, improved efficiency of assembling again greatly, compared with prior art turnout doubles.
