Abstract
The utility model discloses the circuit board of an adapter, which comprises a board substrate, and an electronic element arranged on the board substrate. The middle part of the upper top edge of the board substrate is provided with a threading clamping part. Two matched recesses are parallelly arranged at an interval at the lower bottom edge of the board substrate. The bottom edges of the two mated recesses are horizontally provided with metal jumper wires connected with the electronic element. The circuit board of the adapter is artful and reasonable in structural design. Due to the adoption of the threading clamping part, a wire can be conveniently drawn out of the circuit board. Meanwhile, the board substrate can be conveniently and quickly positioned and fixed inside the cover body of the adapter. Under the spacing and guiding effect of the matched recesses, metal connecting elastic sheets can be accurately abutted against the metal jumper wires. The condition that due to the inaccurate alignment, the normal combination or the current conduction cannot be realized can be avoided. The cooperation is facilitated to be tight and stable and the electrical conductivity is greatly improved. In addition, the circuit board of the adapter has the advantages of simple and compact integral structure, easy realization and low cost, and is favorable for wide popularization and application.
Description
Technical field
The utility model relates to the power supply adaptor technical field, is specifically related to a kind of adapter circuit plate that is applied on power supply adaptor.
Background technology
The electric equipment products of most tool mobilitys, all is furnished with power supply adaptor, but utilize simultaneously the battery of recharge as supply of electric power, these electrical equipment comprise: panel computer, mobile phone, notebook computer, electric game machine, electric tool, printer, walkman etc., the user can be plugged in power supply adaptor the power connection of above-mentioned electrical equipment, can but the battery of the recharge of inside be charged, can enjoy the convenience of carry-on use after electric power is full of, use until electric power is finished recharge again.
The power supply adaptor of selling on the market at present is varied, and it has different design concepts separately, makes every effort to reach the instructions for use of different user.Although these power supply adaptors can roughly satisfy instructions for use, but the board design in it is unreasonable, be difficult to this circuit board is connected with metal on plug-in pin the shell fragment connection of conflicting, generally when do coordinating, malposition when entering very easily appears, and cause normally making metal connection shell fragment and circuit board to do stable bond, and then make in conjunction with the time occur can't On current situation, and circuit board all is fixed by screws on bottom, and the assembling trouble affects production efficiency.
The utility model content
The purpose of this utility model is, for above-mentioned deficiency, provides a kind of structural design ingenious, reasonable, and is convenient for assembly and can be connected with metal shell fragment and carry out good fit adapter circuit plate.
For achieving the above object, technical scheme provided by the utility model is: a kind of adapter circuit plate, it comprises board substrate and is arranged on electronic element on this board substrate, the upper topside centre position of described board substrate is provided with a threading screens, the interval, bottom of this board substrate has two adaptive recess side by side, and is provided with in the position, base of this adaptive recess level the metal jumper that is connected with described electronic element.
As a kind of improvement of the present utility model, the appearance profile of described board substrate is a rectangle, and its four corners are provided with circular arc chamfering.
As a kind of improvement of the present utility model, the thickness of described board substrate is 0.5～1.3 millimeter.
As a kind of improvement of the present utility model, the spacing distance between two adaptive recess equals the length of described threading screens.
The beneficial effects of the utility model are: the utility model structural design is ingenious, reasonable, can conveniently electric wire be drawn by the threading screens, fast and easy is located board substrate and is fixed in the lid of adapter simultaneously, and under the spacing guide effect of adaptive recess, can make metal connect shell fragment and precisely conflict on metal jumper, stop malposition when coordinating, cause normally combination or can't On current etc. situation, be beneficial to cooperation and cooperation tight, stable, greatly improved conductivity; Overall structure is simple, compact in addition, is easy to realize, cost is low, is beneficial to extensively to promote the use.
Below in conjunction with accompanying drawing and embodiment, the utility model is further illustrated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment, referring to Fig. 1, Fig. 2 and Fig. 3, a kind of adapter circuit plate that the present embodiment provides, it comprises board substrate 1 and is arranged on electronic element 2 on this board substrate 1, the upper topside centre position of described board substrate 1 is provided with a threading screens 3, the interval, bottom of this board substrate 1 has two adaptive recess 4 side by side, and is provided with in the position, base of this adaptive recess 4 level the metal jumper 5 that is connected with described electronic element 2.
The appearance profile of described board substrate 1 is a rectangle, and its four corners are provided with circular arc chamfering.
In the present embodiment, the thickness of described board substrate 1 is preferably 0.8 millimeter.In other embodiment, the thickness of described board substrate 1 also can be 0.5～1.3 millimeter.
Spacing distance between two adaptive recess 4 equals the length of described threading screens 3.Structural design is ingenious, reasonable, when convenient location is fixing, also facilitates electric wire is drawn.
During assembling, can conveniently electric wire be drawn by threading screens 3, fast and easy is located board substrate 1 and is fixed in the lid of adapter simultaneously, and under the spacing guide effect of adaptive recess 4, can make metal connect shell fragment and precisely conflict on metal jumper 5, stop malposition when coordinating, cause normally combination or can't On current etc. situation, be beneficial to cooperation and cooperation tight, stable, greatly improved conductivity.
The announcement of book and instruction according to the above description, this utility model those skilled in the art can also change and revise above-mentioned execution mode.Therefore, the embodiment that discloses and describe above this utility model is not limited to also should fall into some modifications and changes of this utility model in the protection range of claim of this utility model.In addition, although used some specific terms in this specification, these terms do not consist of any restriction to this utility model just for convenience of description.As described in the utility model above-described embodiment, adopt structure same or analogous with it and the circuit board of other structure of obtaining, all in the utility model protection range.
