Abstract
To bring the pressure welding protruded pieces into firm contact with a frame body for abating the noise due to oscillation, etc., further regulating the cover warping by a method wherein a frame body is covered with a cover so as to cover a part of the frame body so that the protruded pieces may be pressure-welded onto the frame body to bring the sides of protruded and recessed parts into resilient contacts. A frame body is covered with a cover 9 so as to cover the opened part 6 of the frame body 1. At this time, the oblique part 14 of the pressure welding protruded piece 10 abuts against the protrusion 7 provided on a side board 2 while that 14 of the protruded piece 12 against the protrusion 8 provided on the other side board 3. When the cover 9 is pushed into the fame body 1 in such a state, the pressure welding protruded pieces 10, 11, 15, 16 in the pressure welded state respectively onto the side covers 2, 3, 4, 5 shift the cover 9 downward until it hits the end of the frame body 1 for fitting the cover 9 to the frame body 1. At this time, the upper part of the cover 9 is drawn in the arrow C direction while the lower part is drawn m the D direction, so that the protrusions 7, 8 is brought into relisilent contact with the sides of the pressure welding protruded pieces 10, 11.
Description
The present invention relates to the electronic installation of a kind of television tuner, modulator (amplitude modulator) etc., particularly relate to the electronic installation (be e-machine or instrument, below all abbreviate electronic installation as) of the mounting structure of a kind of framework and lid.
At first see also Fig. 7, shown in Figure 8, existing electronic installation has the metal framework 20 of box-shaped, this framework 20 is provided with mutual opposing sideplates 21,22 and mutual opposing sideplates 23,24, this side plate 23,24 is provided with notch 23a, 24a to the position of oblique side-lower, and another is distolateral to be opened portion 20a.
In framework 20, accommodate and be equiped with the electronic circuit component (not shown), simultaneously, be provided with the terminal board (not shown) of deriving electronic circuit to the outside at above-mentioned notch 23a, 24a.
This framework 20 is provided with the metal lid 25 of rectangular shape, this lid 25 its mutual opposed side edges 25a, 25b relatively are provided with crimping tab 26,27 downwards, in addition, its another mutual opposed side edges 25c, 25d are provided with crimping with tab 28,29 at oblique side-lower.
Above-mentioned crimping in tiltedly side-lower setting does not match the position that formation is staggered with tab 28,29 and above-mentioned notch 23a, 24a.
This lid 25 covers like that with the opened portion 20a that covers framework 20 and is located on the framework 20, the crimping of lid 25 with tab 26,27,28,29 respectively elasticity be connected on the side plate 21,22,23,24 of framework 20.
As shown in Figure 8, lid 25 is installed on the framework 20, at lid 25 mutual opposed side edges 25c, 25d, is respectively equipped with the crimping tab 28,29 to oblique side-lower.Crimping is not provided with crimping tab with tab 29 in its opposed side edges 25c side in its opposed side edges 25d side and crimping with tab 28.
Join to the elasticity of side plate 23 with tab 28 by crimping, make opposed side edges 25d along the arrow directions X to side 25c side shifting, again, join to the elasticity of side plate 24 with tab 29 by crimping, make opposed side edges 25c along arrow Y direction to side 25d side shifting, like this, then make 25 states that are distortion that cover.
Because existing electronic installation moves to opposed side edges 25c, 25d by cover 25 crimping with tab 28,29, make crimping with tab 28,29 and side plate 23,24 contact a little less than, have the phenomenon that produces noise owing to vibrating.
Because lid 25 produces distortion, so the outward appearance of product is plain, makes the value of product to reduce.
As known from the above, existing electronic installation, the crimping of lid is not moved to the side of crimping with tab is set with tab, so with a little less than crimping contacts with the side plate of tab, when situation such as vibration takes place, be easy to generate noise.
Because the drawback that above-mentioned existing electronic installation exists, the inventor is based on rich practice experience and professional knowledge, through constantly studying, design, and after studying sample repeatedly and improving, creates the present invention finally.
Main purpose of the present invention is, overcome the defective that existing electronic installation exists, and provide a kind of electronic installation of new structure, make its crimping more firm with contacting of framework with tab, can limit reversing of lid, make when situations such as vibration take place, can not produce noise, and can improve the value of commodity.
The objective of the invention is to realize by following technical scheme.The electronic installation that proposes according to the present invention is to have the metal lid of crimping with tab by the metal framework that is provided with opened portion and at periphery, this covers with the above-mentioned crimping above-mentioned framework of tab clamping, and cover at least a portion opened portion of above-mentioned framework, either party of above-mentioned framework and above-mentioned lid is provided with protuberance, its opposing party then is provided with recess, and the side of raised part and above-mentioned recess Elastic Contact mutually constitutes.
The present invention is provided with protuberance by giving prominence to foreign side in framework, and above-mentioned covering is provided with recess and constitutes between crimping is with tab.
The present invention is provided with recess by the opened portion side in framework, covers crimping and is provided with protuberance with tab and constitutes.
Have, the present invention is that the leading section at recess is provided with rake and constitutes again.
Also have, the present invention is by having rectangular-shaped lid, on the position on relative two limits of this lid, only be formed with the crimping tab in a side position, when raised part and above-mentioned recess elasticity are joined, constituting with the framework crimping of tab is more firm with crimping.
The present invention compared with prior art has tangible advantage and good effect.By above technical scheme as can be known, electronic installation of the present invention is provided with the metal framework of opened portion, be provided with the lid of crimping at periphery with tab, either party of framework and lid is provided with protuberance, the opposing party is provided with recess, resemble and cover on the framework at least a portion opened portion that covers framework, crimping is crimped on the framework with tab, simultaneously the side elastic of itself and protuberance and recess joins, so crimping with tab to there not being crimping tab side shifting, make crimping firm with the contact of the framework of tab, when situations such as vibration take place, can not produce noise, can limit reversing of lid, can improve the value of product.
Because framework is provided with protuberance to foreign side is outstanding, cover crimping and constitute with being provided with recess between tab, again owing to be provided with recess, cover crimping and be provided with protuberance with tab and constitute, so can limit the position of covering by simply constructing in the opened portion side of framework.
Have, the leading section of recess is provided with rake again, and protuberance inserts to recess easily, has improved transaction capabilities.
Also have, has rectangular-shaped lid, the mutual alignment on relative two limits of this lid, only be formed with the crimping tab, when protuberance and recess elasticity are joined, make crimping more firm with tab and framework crimping in a side position, crimping is with a tab side or when asymmetricly existing only on the relative position on particularly relative two limits, can limit the position of lid, crimping is more firm with contacting of framework with tab, and noiseless electronic installation can be provided.
