The utility model has the advantages of good connecting reliability of the pins and the circuit board, simple connecting structure, easy production and manufacture of the parts and easy assembly of the products.

Description

A kind of power supply adaptor
Technical field
The utility model relates to a kind of power supply conversion equipment for small portable electronic device and electronic apparatus, especially a kind of power supply adaptor.
Background technology
Existing power supply adaptor is the power supply conversion equipment for small portable electronic device and electronic apparatus, and it is by loam cake, lower cover, the pin that covers down, form with the lead that links to each other with circuit board with the circuit board in the loam cake that pin is connected.Circuit board in the pin of power supply adaptor and the loam cake mainly is communicated with by dual mode: a kind of connected mode is for to be connected with pin by conducting strip or the lead that is welded on the circuit board, and the production technology of this connected mode is loaded down with trivial details, and product is difficult assembles; Another kind of mode is an end reflexed of the conducting strip that connects of pin, forms spring function, is communicated with point pressure tight fit on the circuit board.The reflexed end of this connected mode conducting strip is easy to generate elastic fatigue, and the reliability that pin is communicated with circuit board is affected, and directly influences the functional reliability of power supply adaptor.
The utility model content
The utility model purpose is to provide a kind of pin and circuit board connection reliability good, and syndeton is simple, and parts are easy to production and processing, and product is easy to the power supply adaptor of assembly.
For achieving the above object, technical solutions of the utility model are: power supply adaptor by loam cake, lower cover, the pin that covers down, with loam cake that pin is connected in circuit board and form with the lead that circuit board joins, circuit board is connected with pin by the power spring that compresses; The loam cake inwall of power supply adaptor is provided with the spacing preiection that cooperates with circuit board, and circuit board is by the effect and the power spring compression fit of spacing preiection.
One end of described power spring is connected with pin, the point pressure tight fit on the other end and the circuit board.
Described power spring links to each other with pin by brace, an end of brace and power spring clamping, and the other end is connected with pin.
Described connected mode can also be that the elongated end of power spring is socketed on the pin, covers down to be provided with the limit casing that prevents the power spring displacement.
The elongated end of described power spring is clipped between the convex edge and the terminal stator of riveting of pin of pin.
After adopting said structure, because circuit board is connected with pin by the power spring that compresses; The loam cake inwall of power supply adaptor is provided with the spacing preiection that cooperates with circuit board, and circuit board is by the effect and the power spring compression fit of spacing preiection.The production technology of this structure is simple, and the more important thing is product when assembling only needs lower cover, circuit board and loam cake are assembled into together, just can realize being communicated with of pin and circuit board, and the functional reliability of this structure is good.

Embodiment
In the utility model power supply adaptor embodiment 1 shown in Figure 1, power supply adaptor is formed by the circuit board 4 in the pin 3 on loam cake 1, lower cover 2, the lower cover 2, the loam cake that is connected with pin 31 with the lead 5 that circuit board 4 joins.Contact point 6 on the circuit board 4 is connected with pin 3 by the power spring 7 that compresses; Loam cake 2 inwalls of power supply adaptor are provided with the spacing preiection 8 that cooperates with circuit board 4, and when the power supply adaptor assembling was finished, at this moment circuit board 4 had just realized the connection of pin 3 with circuit board 4 by the effect and power spring 7 compression fit of spacing preiection 8.Power spring 7 links to each other with pin 3 by brace 9, an end of brace 9 and power spring 7 clampings, and the other end is connected with pin 3.This syndeton parts are easy to processing and assembly.
In Fig. 2 and the utility model power supply adaptor embodiment 2 shown in Figure 3, power spring 7 one ends of power supply adaptor cooperate with the contact point 6 on the circuit board 4, and are loaded in the limit casing 10.Other end elongated end 11 is a helical form, and is socketed on the joint pin 12 of pin 3 ends.Joint pin 12 is provided with spiral draw-in groove and can cooperates with the elongated end 11 of power spring 7.This structure can conveniently connect power spring 7 and pin 3.
In Fig. 4 and the utility model power supply adaptor embodiment 3 shown in Figure 5, the power spring 7 of power supply adaptor is different with embodiment 2 with the connected mode of pin 3.Power spring 7 elongated ends in the power supply adaptor are socketed on the pin 3, and lower cover 2 is provided with the limit casing 10 that prevents power spring 7 displacements.The elongated end of power spring 7 is clipped between the convex edge 13 and pin 3 terminal stators 14 of riveting of pin 3.This syndeton is simpler, and is convenient to assemble and can enhances productivity.The functional reliability of power supply adaptor also is improved.
