For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.A lot of details have been set forth in the following description so that fully understand the utility model.But the utility model can be implemented much to be different from alternate manner described here, those skilled in the art can be in the situation that do similar improvement without prejudice to the utility model intension, so the utility model is not subject to the restriction of following public concrete enforcement.
It should be noted that, when element is called as " being fixed in " another element, can directly can there be element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may have centering elements simultaneously.
Unless otherwise defined, all technology that this paper is used are identical with the implication that belongs to the common understanding of those skilled in the art of the present utility model with scientific terminology.The term used in instructions of the present utility model herein, just in order to describe the purpose of concrete embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise one or more relevant Listed Items arbitrarily with all combinations.
Referring to Fig. 1 and Fig. 2, is the camera module 100 in an embodiment.Camera module 100 comprises camera lens 110, image sensor 120 and dustproof frame 130.
Described camera module 100 is applied in the electronic equipment in an embodiment, and this electronic equipment comprises circuit board and this camera module 100.Particularly, electronic equipment can be digital camera, notebook computer, panel computer or mobile phone etc.For convenience of description, below take mobile phone describes as embodiment.Certainly, camera module 100 can also be applied in above-mentioned other electronic equipment to take pictures being used for.
Be provided with the connector that the conducting terminal 122 with image sensor 120 sides is complementary on circuit board.Connector is connected with the conducting terminal 122 of image sensor 120 sides, and then realizes that camera module 100 is electrically connected to circuit board.
While being incorporated on circuit board by the camera module 100 in present embodiment, conducting terminal 122 contacts with the connector on circuit board, realizes being electrically connected to of camera module 100 and circuit board.Light arrives image sensor 120 and produces signal of video signal via the eyeglass in lens barrel 112, microscope base 114, by conducting terminal 122, with the connector on circuit board, is electrically connected to and signal of video signal is transferred on the circuit board of electronic equipment.
For ease of assembly, the cross-sectional area of the microscope base of camera module 100 114 is arranged to be less than to the cross-sectional area of image sensor 120, so the marginal portion 120a of image sensor 120 can expose microscope base 114, exposed outside microscope base 114.
Particularly, dustproof frame 130 can comprise many frame 130a.Many frame 130a is one-body molded.Certainly, in other embodiment, can also by the mode of assembling, form by many frame 130a.Particularly, in the present embodiment, microscope base 114 is tetragonal body, and image sensor 120 is tetragonal platy structure, so image sensor 120 is exposed the marginal portion 120a of microscope base 114, is four end to end chimbs.Accordingly, dustproof frame 130 is the dustproof frame 130 that comprises four edges frame 130a.130a is one-body molded for the four edges frame, form sheathed and be adhered to the dustproof frame 130 of microscope base 114 sidewalls, dustproof frame 130 is covered in along the axial direction of lens barrel 112 the marginal portion 120a that image sensor 120 is exposed microscope base 114, the four edges frame 130a of dustproof frame 130 is covered in four chimbs that image sensor 120 is exposed microscope base 114, prevents that dust from falling into the conducting terminal 122 of image sensor 120 sides and affecting electric conductivity.
Certainly, when microscope base 114 is other gengon, the marginal portion 120a that image sensor 120 is exposed microscope base 144 also is polygon accordingly, as triangle, pentagon, hexagon etc., so dustproof frame 130 also is set to three limits, five limits, hexagon etc. accordingly, as long as guarantee that dustproof frame 130 is held in microscope base 114 sidewalls, and be covered in the marginal portion 120a that image sensor 120 is exposed microscope base 114, prevent that the conducting terminal 122 that dust falls into image sensor 120 sides from getting final product.
Particularly, the shape of dustproof frame 130 can with image sensor 120, to expose the shape of marginal portion 120a of microscope base 114 identical.Now, dustproof frame 130 is sheathed and while being adhered to microscope base 114 sidewall, dustproof frame 130 can shelter from along the axial direction of lens barrel 112 the marginal portion 120a that image sensor 120 is exposed microscope base 114 fully, prevent that dust from falling into the conducting terminal 122 of image sensor 120 sides, avoids affecting the electric conductivity of conducting terminal 122.
Particularly, dustproof frame 130 can be the plastic dust frame.The low cost of manufacture of plastics, quality is light, and is good insulating body.Dustproof frame 130 can be opaque plastic dust frame, when assembling, can first the CMOS image sensor be incorporated on the connector of circuit board, then opaque plastic dust frame is placed in to the microscope base lateral wall, makes dustproof frame be held in the microscope base sidewall.In present embodiment, can also be transparent plastic dust frame, when assembling, can first transparent plastic dust frame be placed in and be bonded in the microscope base lateral wall, and then CMOS is incorporated on the connector on circuit board.Owing to being transparent plastic dust frame, when being incorporated on the connector on circuit board by the CMOS image sensor, can not affect sight line.
In present embodiment, also be provided with the first 114a of fool proof section on microscope base 114, the side of dustproof corresponding the first 114a of fool proof section of frame 130 also is provided with the second 130b of fool proof section.The first 114a of fool proof section be set be anti-loaded or wrongly installed when preventing that camera module 100 is on being assembled to circuit board.It is in order to facilitate integrated dustproof frame 130 to be sheathed on quickly and easily microscope base 114 lateral walls that the second 130b of fool proof section is set.
Particularly, the first 114a of fool proof section can be the first projection extended to form along the axial direction of lens barrel 112 by microscope base 114 sidewalls, the second 130b of fool proof section the second projection that dustproof frame 130 extends to form along the axial direction of lens barrel 112 of serving as reasons.Arrange when the first projection and the second projection can effectively prevent from assembling and make mistakes, ease of assembly.Certainly, in other embodiment, the first 114a of fool proof section also can be for being opened in the first fool proof groove on microscope base 114, and the second 130b of fool proof section also can be for being opened in the second fool proof groove on dustproof frame 130.
Above-mentioned camera module 100 and electronic equipment, because dustproof frame 130 is covered in along the axial direction of lens barrel 112 the marginal portion 120a that image sensor 120 is exposed microscope base 114, so exposing the marginal portion 120a of microscope base 114 frame 130 that prevented dust, image sensor 120 shelters from, rather than outside exposed, dustproof frame 130 can block dust, avoids dust to fall on the conducting terminal 122 of image sensor 120 sides and affects electric property.
The above embodiment has only been expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
