Embodiment
For ease of skilled artisan understands that the technical solution of the utility model, below by technical side of the present utility model
Case is described in further detail in conjunction with specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of SD card adapter 100 includes the first housing 20, the second housing 40 and electricity
Road plate 30；
The circuit board 30 is provided with the first spacing hole 31 and the second spacing hole 32；First housing 20 is provided with first
The limited post 22 of limited post 21 and second；First spacing hole 31 and first limited post 21 connect, second spacing hole
32 and second limited post 22 connect, connect the circuit board 30 and first housing 20, prevent the SD card from transferring
The circuit board 30 loosens device 100 in use, so as to cause the loose contact of SD card adapter 100, influences to use；It is described
Second housing 40 covers the circuit board 30 in side of the circuit board 30 away from the first housing 20, second housing 40 and described
First housing 20 is fixed, so as to which the circuit board 30 is fixed between first housing 20 and second housing 40, institute
State the first housing 20 and second housing 40 protects the circuit board 30, reduce the materials such as the water in air and dust and be adhered to
Circuit board 30, and cause the Damage by Short Circuit of circuit board 30；It is simple in construction, it is easy to use.Above-mentioned technical proposal ratio is set in circuit board 30
Limited post is put, while sets the technical scheme cost of spacing hole cheap in the first housing 20, because circuit board 40 belongs to production board,
If necessary to set limited post on circuit board 30, it is necessary to the welded limiting post on circuit board 30.
Second housing 40 is provided with support column 41, and the support column 41 is only butted on circuit board 30；Due to difficult in production
To ensure that second housing 40 and the circuit board 30 are bonded, when between second housing 40 and the circuit board 30 due to
It is not bonded, easily causes the crimp of 100 second housing of SD card adapter 40, the caused easily damaged circuit of crimp
Plate 30；When there is irregular tip raised on the second housing 40, the easily damaged circuit board 30 of projection.In order to ensure
Support strength between the housing 40 of second circuit board 30 and second, one or more support columns are set on second housing 40
41, circuit board 30 is damaged so as to reduce external force the second housing 40 of extruding, setting the technical scheme of support column 41 has structure simple
Singly, the advantages of safe and reliable.
Second housing 40 is fixed with first housing 20 using ultrasonic bonding；Ultrasonic bonding is generally used for moulding
Material welding, it is the high-tech technology of welding thermoplastic articles, can replaces being bonded with glue completely.Various thermoplastic cement parts
Ultrasonic fusing technology can be used to be handled, without solubilizer, bonding agent or other supplements.Its principle is by upper
Ultrasonic energy is sent to welding zone by weldment, big using acoustic resistance at the interface of two welding, and producing localized hyperthermia makes weldment
It is merged；It is not connect bolt during ultrasonic bonding, nail, buckle, the material knot such as welding material or adhesive
Be combined, it than traditional adhesive or viscose glue water speed faster, and drying time is also very fast, and the process of welding can be with
It is easily achieved automatically, can easily customizes, be soldered with adapting to the product of all types of The concrete specifications.
The SD card adapter 100 includes SD card socket 60；Second housing 40 is provided with the second solder joint 42 and the 3rd
Solder joint 43, second solder joint 42 and the 3rd solder joint 43 are distributed in the both sides of SD card socket 60；First housing 20
Ultrasonic fusing is fixed at the solder joint 43 of the second solder joint 42 and the 3rd with second housing 40, the SD card socket 60 by
The first housing 20 and the second housing 40 around SD card socket 60 are easily caused in the plug of SD card to separate, and the He of the second solder joint 42 is set
3rd solder joint 43 is advantageous to strengthen the bonding strength of the first housing 20 and the second housing 40, so that the structure of SD card socket 60 is steady
It is fixed, increase the service life of the SD card adapter 100.
Second housing 40 also includes the first solder joint 44, and first solder joint 44 is described away from the SD card socket 60
First housing 20 connects with second housing 40 at first solder joint 44；Strengthen the housing of the first housing 20 and second
40 bonding strength, extend the service life of the SD card adapter 100.
The SD card adapter 100 also includes write-protect switch 50, and the write-protect switch 50 disclosure satisfy that the SD card
Adapter 100 realizes read-only function or read-write capability.
Above is preferred embodiment of the present utility model is not used in restriction the scope of protection of the utility model.It should approve,
The non-creativeness that those skilled in the art is made after it understanding of technical solutions of the utility model changes and deformation, should also belong to
In the scope of protection of the utility model.
