Abstract
The utility model provides an element pin structure suitable for a printed circuit board. The printed circuit board is provided with a plurality of jacks, wherein an element mainly comprises a body and a plurality of pins arranged at one side of the body, and two adjacent pins are welded by solder paste, so that the welded pins can be simultaneously inserted in the plug hole. Preferably, according to the element pin structure, the solder paste is heated and melted after the welded pins are subjected to reflow soldering, and the adjacent pins are opened and are tightly attached on a hole wall of the jack. According to the element pin structure provided by the utility model, two adjacent pins are welded by the solder paste and then are simultaneously inserted into the jack, and after a second reflow soldering, as the solder paste is heated and melted, the pins are elastically opened and are tightly attached on the hole wall of the jack, and disengagement with the jack is not easy.
Description
Technical field
The utility model relates to a kind of element leg structure, relates in particular to a kind of element leg structure and easily inserts or anticreep on printed circuit board (PCB).
Background technology
As shown in Figure 1, element shown in the figure 10 comprises the pin 101 that its body and this body one side are provided with, two pins that separate 101 of this element 10 need insert in the jack 201 that printed circuit board (PCB) 20 is provided with simultaneously, because this two pin that separates 101 is when inserting jack 201, pin 101 contacts with the hole wall of jack 201, its frictional resistance is larger, is difficult for inserting, and produces easily pin 101 causes pin 101 bendings when inserting situation.
When carrying out second time reflow soldering, because element is downward, be used for the hole wall that fixing pin 101 can't tighten jack 201, cause easily floating highly, even fall part.
Summary of the invention
In view of the above problems, the utility model provides a kind of element leg structure, easily inserts or anticreep on the printed circuit board (PCB) easily.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of element leg structure, it is applicable on the printed circuit board (PCB), this printed circuit board (PCB) is provided with several jacks, wherein, several pins that described element mainly comprises body and is arranged at this body one side utilize tin cream to weld together to make this pin that welds together to insert in the jack simultaneously in twos between the adjacent pin.
Better, the utility model provides a kind of element leg structure, and wherein, the described pin that welds together is its tin cream melted by heating after reflow, this in twos adjacent pin open and be adjacent to the hole wall of jack.
Compared to prior art, the utility model provides a kind of element leg structure, not only utilize tin cream to weld together so that insert simultaneously in the jack between the adjacent pin in twos, and utilizing after the reflow soldering second time, adjacent pin is because the tin cream melted by heating in twos, elastic force opens and is adjacent to the hole wall of jack, is not easy to break away from jack.

Fig. 3 is the schematic diagram after the tin cream melting behind the pin insertion jack described in the utility model
Embodiment
Please refer to Fig. 2 and shown in Figure 3, the utility model provides a kind of element leg structure, and it is applicable on the printed circuit board (PCB) 20, and this printed circuit board (PCB) 20 is provided with several jacks 201.
Wherein, described element 10 is the plug-in unit class component, and several pins 101 that it mainly comprises body and is arranged at this body one side, the pin 101 of 10 liang of two phase flows of described element need to insert in the same jack 201 that this printed circuit board (PCB) 20 is provided with simultaneously.
In present embodiment, as shown in Figure 2, this element 10 utilizes tin cream 30 to weld together between the adjacent pin 101 in twos, so, so that this pin that welds together 101 inserts in the jack 201 simultaneously.
Again, refer again to shown in Figure 3.When this pin that welds together 101 inserts on the printed circuit board (PCB) 20 behind the jack 201 simultaneously, after the reflow soldering second time, tin cream 30 melted by heating on the described pin that welds together 101, since this in twos adjacent pin 101 have certain elastic force, after tin cream 30 melted by heating, this in twos adjacent pin 101 with certain elastic force opens and is adjacent to the hole wall of jack 201, reaches this element 10 is fixed in purpose on this printed circuit board (PCB) 20.
Compared to prior art, the utility model provides a kind of element leg structure, not only utilize tin cream 30 to weld together between the adjacent pin 101 in twos so that insert simultaneously in the jack 201 on the printed circuit board (PCB) 20, and utilizing after the reflow soldering second time, adjacent pin 101 is because tin cream 30 melted by heating when reflow soldering in twos, elastic force opens and is adjacent to the hole wall of jack 201, is not easy to break away from jack 201.
Claims (2)
1. element leg structure, it is applicable on the printed circuit board (PCB), this printed circuit board (PCB) is provided with several jacks, it is characterized in that, several pins that described element mainly comprises body and is arranged at this body one side utilize tin cream to weld together to make this pin that welds together to insert in the jack simultaneously in twos between the adjacent pin.
2. element leg structure according to claim 1 is characterized in that, the described pin that welds together is its tin cream melted by heating after reflow, this in twos adjacent pin open and be adjacent to the hole wall of jack.
