Line relative positional accuracy is ± 0.3mm, and because positioning accuracy is not high, having the insertion of FPC plug golden finger, connector is too deep or mistake
Shallow unfavorable condition；It needs whether sight check plugs in place after FPC insertion connector, influences packaging efficiency.
Utility model content
The main purpose of the utility model is the reinforcement supplementary structure for proposing a kind of FPC plug golden finger, it is intended to be changed existing
The reinforced structure of some FPC plug golden fingers, improves the intensity of plug golden finger, facilitates the plug at plug golden finger end and determines
Position.
To achieve the above object, the utility model proposes a kind of FPC plug golden finger reinforcement supplementary structure, including
FPC matrix, the FPC base end are equipped with plug golden finger, and the plug golden finger is plugged in connector interface, described to insert
Pulling out golden finger surface mount has the first stiffening plate, and the first stiffening plate surface mount has the second stiffening plate, first reinforcement
The width of plate is equal to the width of the plug golden finger, and the length of first stiffening plate is greater than the length of the plug golden finger
Degree, and the plug golden finger end face is concordant with the side of first stiffening plate, first stiffening plate and plug gold
The overall thickness of finger is equal to the connector interface height；The second reinforcement board width is equal to the plug golden finger width,
Second stiffening plate is equal to described close to the side of plug golden finger end and the horizontal distance of the plug golden finger end face
Plug the length of golden finger.
Preferably, first stiffening plate is set as PI stiffening plate.
Preferably, second stiffening plate is set as FR4 stiffening plate.
Preferably, the thickness of second stiffening plate is set as 0.3mm.
Compared with prior art, the utility model has the beneficial effects that by the double-deck benefit of plug golden finger surface superposition
Strong plate, improve plug golden finger intensity, meanwhile, by be arranged upper layer stiffening plate, realize plug golden finger fast insert-pull and
Positioning, and reinforced structure is attached on plug golden finger by the mode that automatic machine patch can be used, it is ± 0.1mm that automatic machine, which pastes precision,
Positioning accuracy is greatly improved, to improve the installation progress of plug golden finger, substantially increases production efficiency.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the side view that the utility model FPC plugs golden finger end reinforcement supplementary structure；
Fig. 2 is the front view that the utility model FPC plugs golden finger end reinforcement supplementary structure；
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific embodiment
A kind of reinforcement supplementary structure for FPC plug golden finger that the present embodiment proposes, including FPC matrix 1, the FPC base
1 end of body is equipped with plug golden finger 2, and the plug golden finger 2 is plugged in connector interface (not shown), the plug
2 surface mount of golden finger has the first stiffening plate 3, and 3 surface mount of the first stiffening plate has the second stiffening plate 4, and described first mends
The width of strong plate 3 is equal to the width of the plug golden finger 2, and the length of first stiffening plate 3 is greater than the plug golden finger 2
Length, and plug 2 end face 21 of golden finger is concordant with the side of first stiffening plate 3, first stiffening plate 3 and institute
The overall thickness for stating plug golden finger 2 is equal to the connector interface height；Second stiffening plate, 4 width is equal to the plug gold
2 width of finger, second stiffening plate 4 is close to the side of plug 2 end of golden finger and the water of plug 2 end face 21 of golden finger
Flat distance is equal to the length of the plug golden finger 2.
It should be noted that plug golden finger 2 directly can be inserted into connector interface, institute when operator plugs FPC
The length for stating plug golden finger 2 is equal to the depth of connector interface, the overall thickness of the first stiffening plate 3 and the plug golden finger 2
Equal to the connector interface height；There is the second stiffening plate 4 since 3 surface of the first stiffening plate increases, and described second mends
Strong plate 4 is equal to the plug gold close to the side of plug 2 end of golden finger and the horizontal distance of plug 2 end face 21 of golden finger
The length of finger 2, therefore, during grafting, side and connection of second stiffening plate 4 close to plug 2 end of golden finger
When device interface lateral surface abuts, the complete grafting of the plug golden finger 2 and connector interface plug 2 grafting of golden finger in place,
It is easy to operate to complete the grafting operation of plug golden finger 2, grafting efficiency is substantially increased, without carrying out whether grafting arrives
