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

Electronic component
[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]
The purpose of this utility model is to provide a kind of new electronic component, and it can guarantee to electrically connect preferably with circuit board.
In order to reach above-mentioned creation purpose, the utility model electronic component, be used to be installed in circuit board, this circuit board is provided with tin cream, this electronic component comprises insulating body and is contained in conducting terminal in the insulating body, wherein conducting terminal is provided with weld part, and this weld part protrudes in insulating body and can insert in the tin cream, it is characterized in that: this weld part top is provided with scolder.
Compared with prior art, the weld part top of the conducting terminal of the utility model electronic component is provided with scolder, when conducting terminal and circuit board weld, the scolder melted by heat of weld part top, increased amount of solder required when welding, increased the fastness of welding, guaranteed to electrically connect preferably with circuit board.

[embodiment]
Below in conjunction with accompanying drawing the utility model electronic component is made and to further describe.
With reference to Fig. 3 and Fig. 4, the utility model electronic component is used to be installed in circuit board 4, comprises insulating body 1, conducting terminal 2 and a tin ball 3 (also can be the scolder of other form), and wherein circuit board 4 is provided with tin cream 40.
Insulating body 1 is provided with accepting groove 10, and this insulating body 1 lower surface upwards is concaved with accommodation space 11.
Conducting terminal 2 is contained in the accepting groove 10 of insulating body 1, and by accommodation space 11, its end is provided with weld part 20, and weld part 20 passes accommodation space 11 and protrudes in lower surface.
Tin ball 3 is positioned at the accommodation space 11 of insulating body 1, is positioned at weld part 20 tops of conducting terminal 2, and contacts with conducting terminal 2.
When being connected with circuit board 4, at first the weld part 20 with the conducting terminal 2 of electronic component inserts in the tin cream 40 of circuit boards 4, heat tin cream 40 fusings then, weld together mutually with the weld part 20 of conducting terminal 2, at this moment, tin ball 3 melted by heat of electronic component deform, be connected together with tin cream 40, thereby increase the fastness of welding.
Certainly, also can in the opening 11 of insulating body 1, establish two tin balls 3 (as shown in Figure 5), conducting terminal between two tin balls 3, and and tin ball 3 contact, also can increase the fastness of welding.
Figure 6 shows that the 3rd embodiment of the utility model electronic component, be with first kind of embodiment difference: in the present embodiment, the lower surface of insulating body 1 is provided with boss 12, and the tin liquor after melting with restriction flows towards periphery and causes short circuit between the terminals of adjacent.
Figure 7 shows that the 4th embodiment of the utility model electronic component, be with second kind of embodiment difference: in the present embodiment, the lower surface of insulating body 1 is provided with boss 12, and the tin liquor after melting with restriction flows towards periphery and causes short circuit between the terminals of adjacent.
Compared with prior art, the weld part top of the conducting terminal of the utility model electronic component is provided with scolder, when conducting terminal and circuit board weld, the scolder melted by heat of weld part top, increased amount of solder required when welding, increased the fastness of welding, guaranteed to electrically connect preferably with circuit board.
