Description
Technical field
The utility model relates to automobile audio technical field, in the automobile audio of specially a kind of anti-screw fragmental texture of band
Frame.
Background technique
With automobile industry development, requirement of the main engine plants to product quality is higher and higher, reaches PPM grades to the statistics of failure
Not, the Aftermarket Claims of quality problems are also executed with further stringent, reduction failure rate, embracing for client can be substantially reduced by reducing claim
Resentment reduces the operation cost of enterprise and promotes the competitiveness of enterprise.
Especially in recent years, as the yield of vehicle is increasing, the demand of automobile audio is also significantly promoted, and with
Function is more enriched, such as navigation, and in limited space, the complexity of PCB is being continuously increased, element envelope used
Fill smaller and smaller, the distance between component is also very small, also has more type to need to arrange 2 or more in center
Wiring board realize many functions and external socket/interface, therefore how effective solution screw hole metal fragment at
For extremely important problem.
Present fixing structure for circuit board is to turn over all over threaded hole, i.e., uses punching on the stationary plane of the wiring board of metal plate center
Technique go out the through-hole of a height about 1 ~ 1.5mm, and with tap tapping, the fixation of Lai Shixian screw.
Existing fixing screws are turned over all over threaded hole, and effective hole depth only has 1.5 ~ 2mm, and thread turns is less, screw
Easily there is removal torque and is substantially reduced to show with screw loosening after vibration-testing in stripped thread torque and to reuse number all lower
As, and tapping procedures processing after being needed individually after mold molding, under efficiency, after tapping in threaded hole easy kish
Clast, be easily assembled in complete machine assembling process in clast can fall on wiring board, lead to potential failure risk, for this purpose, I
Propose the automobile audio center of anti-screw fragmental texture of band a kind of.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of automobile audio center of the anti-screw fragmental texture of band
The problem of being proposed in background technique.
To achieve the above object, the utility model provides the following technical solutions: a kind of automobile of the anti-screw fragmental texture of band
Sound equipment center, including center, center left and right sides top is arranged symmetrically, and there are four extension boards, and offer on four extension boards
Blind hole, extension board top are placed with wiring board, and the screw hole to match with blind hole, installation in screw hole are offered at left and right sides of wiring board
There is screw, screw bottom is fixed in blind hole.
Preferably, center is an integral molding structure with extension board, and middle frame bottom is uniformly provided with heat release hole.
Preferably, screw is self-tapping screw, and the distance between screw bottom end and hole bottom are 3-5mm.
Compared with prior art, the utility model has the beneficial effects that the utility model is used in fixed screw
Self-tapping screw, the depth bounds of self-tapping screw tapping are all effective cooperation ranges, so stripped thread torque and heavy burden use time
Number, which is all significantly more than to turn over, can effectively promote the fixed reliability of screw all over threaded hole, and it is bright not occur removal torque after vibration-testing
The phenomenon that aobvious smaller and loosening, and blind hole can use progressive die straight forming, not need to reuse individually after mold forms
Tapping procedures afterwards improve production efficiency, and the metal fragment generated in self-tapping screw installation can remain in blind via bottom, no
The problem of metal fragment is fallen can occur, improve reliability and stability.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model screw and blind hole attachment structure schematic diagram.
In figure: 1, center；2, extension board；3, blind hole；4, wiring board；5, screw；6, heat release hole.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of automobile audio of the anti-screw fragmental texture of band
Center, including center 1, center 1 select Metal plate, and 1 left and right sides top of center is arranged symmetrically, and there are four extension boards 2, are used for
Wiring board 4 is supported, and offers blind hole 3 on four extension boards 2, blind hole 3 can use progressive die straight forming, not need in mould
Tapping procedures after reusing individually after tool molding, improve production efficiency, wiring board 4, wiring board are placed at the top of extension board 2
4 left and right sides offer the screw hole to match with blind hole 3, and screw 5 is equipped in screw hole, and 5 bottom of screw is fixed in blind hole 3,
Wiring board 4 is fixed on 2 top of extension board by screw 5.
Wherein, center 1 is an integral molding structure with extension board 2, and 1 bottom of center is uniformly provided with heat release hole 6, convenient for dissipating
The heat generated when wiring board 4 works out；
Screw 5 is self-tapping screw, convenient for making the depth bounds of self-tapping screw tapping all be effective cooperation range, stripped thread
Torque and heavy burden access times, which are all significantly more than to turn over, can effectively promote the fixed reliability of screw 5 all over threaded hole, and 5 bottom of screw
The distance between end and 3 bottom hole of blind hole are 3-5mm, and the metal fragment generated in self-tapping screw installation can remain in blind hole 3
Bottom will not occur the problem of metal fragment is fallen, improve reliability and stability.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
