Abstract
The utility model discloses a connecting structure of an adapter power supply input end and a PCB board thereof, wherein the connecting structure has the advantages of low cost and good contact, occupies a small space, and conforms to relevant safety standards. A tower-shaped conductive spring is arranged between the inner end of a power supply pin and the PCB board. The conductive spring is arranged between the inner end of the power supply pin and the PCB board in an inverted manner, wherein the small end of the conductive spring is downward, and the large end is upward. According to the utility model, the tower-shaped conductive spring is arranged between the inner end of the adapter power supply input end and the PCB board; compared with an adapter which uses a complex elastic piece or a bonding wire connection structure in the prior art, the assembled adapter has the advantages of simple assembly, reduced material cost and improved production efficiency; the conductive spring is in fixed interference fit with the inner end of the power supply input end, and fully contacts the bottom surface of the PCB board; the contact resistance is low; and through the structure, electromagnetic interference produced by an insertion moment is greatly reduced.
Description
Technical field
The utility model relates to a kind of adapter, particularly the syndeton of power input and its pcb board in a kind of portable adaptor.
Background technology
Fast development along with electronics technology, nowadays to do exquisiter and exquisiter small and exquisite for adapter, syndeton in adapter of the prior art between power input and its pcb board, the shell fragments that adopt directly contact or by bonding wire connected mode, pcb board are connected with power input with the pad on pcb board more, like this, need to increase a plurality of parts at element instep and could solve the electronic technology difficult problems such as electromagnetic interference, assembling work complex process, manufacturing cost is high, and shell fragment shape need to be done corresponding variation according to the concrete structure in adapter shell, therefore, its shape variation is made trouble and easily affects safety distance, simultaneously, also be subject to the restriction of overall space in shell.Syndeton poor stability, the short-circuit risks of shell fragment of the prior art directly and between pcb board is high, when shell fragment size is large, bend is when more, will makes it when socket power, produce larger electromagnetic interference wave, thereby affect the normal work of adapter.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of cost low, contact, take up room little and meet the adaptor power supplies input of associated safety standard and the syndeton of its pcb board.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The syndeton of adaptor power supplies input of the present utility model and its pcb board, comprise power pin, between described power pin the inner and pcb board, be provided with the power spring that is turriform, this power spring with small end down large end mode be upward inverted between power pin the inner and pcb board.
The small end of described power spring is buckled on the projection that is arranged at power pin the inner with interference fit cover.
Big or small two ends at power spring are connected with respectively auxiliary spring side by side, and the spring linear diameter of this auxiliary spring is greater than the gap between the coil of power spring.
Described auxiliary spring is two circles.
The utility model adopts the power spring of turriform between the inner of adaptor power supplies input and its pcb board, make the adapter of assembling thus compared with the adapter of the complicated shell fragment of available technology adopting or bonding wire syndeton, assembling is simple, material cost declines, production efficiency improves, and because power spring interference fit is fixed on the inner of power input, it fully contacts with pcb board bottom surface, contact resistance is therebetween lower, and this structure can greatly reduce the electromagnetic interference producing because of the moment of pegging graft.

Reference numeral is as follows:
Pcb board 1, power pin 2, the inner 21, projection 22, power spring 3, auxiliary spring 4, drain pan 5, upper casing 6.
Embodiment
As shown in Figure 1,2,3, 4, the syndeton of adaptor power supplies input of the present utility model and its pcb board 1,, between adaptor power supplies pin 2 inner 21 and pcb board 1, the power spring 3 that is turriform is set, power pin 2 inner 21 is cylindrical projection 22, the small end interference fit of power spring 3 snaps onto on this projection 22, the large end of power spring 3 and the bottom surface of pcb board 1 touch, thus power pin 2 is communicated with pcb board 1, this power spring 3, after adapter has assembled, is placed between power pin 2 inner 21 and pcb board 1 with compressive state.
As shown in Figure 5, in order to prevent described power spring 3 to be intertwined mutually when compressed, follow the string, big or small two ends at power spring 3 are connected with respectively two circle auxiliary springs 4 side by side, and the spring linear diameter of this auxiliary spring 4 is greater than the gap between the coil of power spring 3.
The utility model is a kind of new Joining Structure so that adapter is when meeting safety standard requirements, embody produce efficient, reduce costs.The utility model structure can meet corresponding technical parameter and performance index, and assembly manipulation is simple, reliable in function.
The utility model employing power spring 3 dexterously substitute mode makes power supply by having realized reliable connection between input terminal and pcb board 1.
In sum, the utility model adopts over-surplus fit structure between power spring 3 and the cylinder of power input the inner 21, make it meet the requirement of product mechanical function and Electronic Performance parameter completely, thereby reach minimizing part, reduce manufacturing cost, simplify the object that assembling meets again adapter functions requirement.
During assembling, pcb board 1 is packed into after upper casing 6, then the drain pan 5 that installs power spring 3 is tipped in upper casing 6, last ultrasonic bonding sealing.
