Abstract
The utility model relates to the field of electronic components, in particular to an improvement structure of a single-winding panel inductor, which is welded on a PCB. A false pin used for keeping the balance of the center of gravity is added opposite to a pin. Three pins of an inductance component are welded on the PCB so as to increase the welding firmness. In addition, the false pin does not affect other electronic components, can keep the balance of a magnetic core, and firmly fix the magnetic core, thus better processing the phenomenon such as vibration and the like in transportation or work, improving the welding reliability and safety of the inductance component, and having very convenient operation and use.
Description
[technical field]
The utility model relates to the electronic devices and components field, specifically refers to a kind of simplex winding planar inductive structure-improved that is welded on the pcb board.
[background technology]
At present, along with the development of industrialization technology, electronic product more and more trends towards miniaturization, causes the volume of inner components and parts also to be tending towards microminiaturized day by day, but the function of each electronic product inconvenience even more powerful.As shown in Figure 1, be the inductance element of using on the various electronic products 10, be welded on the pcb board by tin cream, though constant weight is arranged but these inductance element 10 volumes are small, and general inductance element only is provided with two metal pins 20,30, is fixed on the pcb board by welding pin 20,30, but because inductance element 10 has certain weight, and pin 20,30 is arranged in a side, and the opposite side of magnetic core cannot be fixed, and will cause inductance element 10 integral body to be subjected to force unbalance; Can occur inductance element 10 uncontrollable bad phenomenon after loading onto pcb board takes place, because of having only two pins 20,30 fixing, in transportation because of vibrations, skew can take place whole center of gravity just might cause that pin 20,30 is loosening, cause inductance element 10 failure weldings, it is bad that rosin joint or open circuit etc. can appear in solder joint, and power supply can not be worked, to directly cause the poor reliability of electronic product, this person of being to use is reluctant to see.
[utility model content]
The technical problems to be solved in the utility model is to cause at inductance element centre-of gravity shift in the existing electronic product that not prison welding is solid, insecure problem, and a kind of simplex winding planar inductive structure-improved is provided.
A kind of simplex winding planar inductive structure-improved, comprise the inductance element main body, the bottom surface of described inductance element main body is provided with first pin and second pin of arranging side by side, also is provided with the 3rd false pin that keeps inductance element main body gravity balance on the bottom surface of wherein said inductance element main body.
Preferably, the line stretcher of described the 3rd false pin is vertical with line stretcher between first pin and second pin.
The described the 3rd false pin is consistent with the height of first pin and second pin.
The utility model simplex winding planar inductive structure-improved increases a false pin that keeps gravity balance on the pin opposite. and make inductance element have three place's pins to be welded on the pcb board, to increase the firmness of welding.Described in addition false pin does not influence other electrical component, magnetic core can be kept balance to reach and firmly fix, and well bears the phenomenons such as vibrations in transportation or the work, has improved inductance element welding reliability and fail safe, and has manipulated very convenient yet.
[description of drawings]
The prior art constructions schematic diagram of Fig. 1 for disclosing;
Fig. 2 is a structural representation of the present utility model.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
See shown in Figure 2, be the utility model simplex winding planar inductive structure-improved schematic diagram, it comprises inductance element main body 10, the bottom surface of described inductance element main body 10 is provided with first pin 20 and second pin 30 of arranging side by side, also be provided with the 3rd false pin 40 that keeps inductance element main body gravity balance on the bottom surface of wherein said inductance element main body 10, the 3rd false pin available metal material is made, as copper, but be not electrically connected with inductance element, make inductance element have three place's pins to be welded on the pcb board, to keep balance, even phenomenons such as chatter in transportation or work, occur, described inductance element main body 10 also not can and pcb board between bad phenomenon such as dry joint or open circuit appear, the reliability and the fail safe that have improved inductance component greatly.
In addition, for the ease of operation and welding, the line stretcher of the described the 3rd false pin 40 is vertical with line stretcher between first pin 20 and second pin 30, can form stable supporting surface; The 3rd false pin 40 is consistent with the height of first pin 20 and second pin 30, can improve the quality and the efficient of welding, is convenient to standard operation.
Above-described only is better embodiment of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
