In view of this, be necessary to provide a kind of electronic component fixed structure in fact, this fixed structure need not to use special Mould Machining, also more easily assembling of electronic component simultaneously.

[summary of the invention]

The utility model purpose is to provide a kind of electronic component fixed structure, and this fixed structure need not to use special Mould Machining, also more easily assembling of electronic component simultaneously.

Implement electronic component fixed structure of the present utility model, this structure is provided with a retainer, this retainer is used for fixing the welding foot of electronic component, and this retainer is provided with a heat-shrinkable T bush, and so retainer can be fixed together by the condensation and the electronic component of thermal shrinkable sleeve; In addition, this fixed structure also is provided with positioning piece, this keeper comprises a supporting bracket and is respectively equipped with perpendicular baffle plate in each end limit of this supporting bracket, and these baffle plates and supporting bracket form a receiving space, and this receiving space is used for accommodating the combination of retainer and electronic component; And outside the combination of keeper and retainer and electronic component, place by a sheathed fixture, electronic component can be fixed on the case of electronic device, so do not need for electronic component independent align member to be set separately, make and assembling thereby be beneficial to.

Compared to prior art, this fixed structure need not use special Mould Machining, and retainer, heat-shrinkable T bush, keeper and fixture, all can buy to obtain on market, thereby save cost, and be beneficial to manufacturing and assembling.

[embodiment]

Ask for an interview shown in Figure 2, the utility model is a kind of electronic component fixed structure, this structure is provided with a retainer 3, the volume of this retainer 3 is identical with the volume of electronic component 7, and this retainer 3 is sleeves on the welding foot 71 that electronic component 7 one ends protrude, and is provided with groove 31 in these retainer 3 relative two sides, again, between relative two grooves 31, be provided with a through hole 32, and groove 31 on this retainer 3 and through hole 32 match with an end welding foot 71 of electronic component 7 at retainer 3 middle parts.

This retainer 3 is arranged with a heat-shrinkable T bush 4 with outer the placing of electronic component 7 close welding foot 71 1 ends, this heat-shrinkable T bush 4 is a rectangle framework, which is provided with the receiving space 40 of accommodating retainer 3 and electronic component 7, these receiving space 40 sizes at room temperature are the sizes less than retainer 3 and electronic component 7, during use, earlier heat-shrinkable T bush is heated, make its expansion, then it is sheathed on retainer 3 and outer the placing of electronic component 7 near welding foot 71 1 ends, will shrink after then waiting heat-shrinkable T bush to be cooled to room temperature, then receiving space 40 diminishes, and combines thereby retainer and electronic component are fixed.
