Abstract
The utility model discloses an electronic element arranged on a circuit board with tin paste, comprising an isolation body and conductive terminals housed in the isolation body. The conductive terminal is provided with a welding part which is protruding out of the isolation body and can be inserted in the tin paste. The utility model is characterized in that the solder is provided above the welding part. Compared with the prior art, the welding part of the conductive terminal of the electronic element of the utility model is provided with solders in the upper part. When the conductive terminal and the circuit board are proceeded to welding, the solder above the welding part is heated to melt, which increases the desired amount of the solder and the fastness of the welding in the process of welding, so as to guarantee the better electrical connection with circuit board.
Description
[technical field]
The utility model relates to a kind of electronic component, especially a kind of electronic component that electrically connects mutually with printed circuit board (PCB).
[background technology]
At present, electronic component generally is connected together by the mode and the circuit board of welding.Prior art can see figures.1.and.2, its electronic component is used for being connected with circuit board 3, wherein circuit board 3 is provided with tin cream 30, electronic component comprises insulating body 1, and some plurality of conductive terminals 2 that are located in the insulating body 1, these terminal 2 afterbodys are provided with welding ends 20, and this welding ends 20 can insert in the tin cream 30 on the circuit board 3, thereafter by heating conducting terminal 2 is fixed with circuit board 3 and be in the same place, realize the electric connection of electronic component and circuit board 3.
Yet the defective of the prior art is: the scolder on the circuit board uses the tin cream amount limited, when tin cream is not enough, causes easily under the situation of failure welding, even causes the situation of solder crack easily, has a strong impact on the electric connection of electronic component and circuit board.
Therefore, be necessary to design a kind of new-type electronic component, to overcome above-mentioned defective.
[summary of the invention]
