Description
Technical field
The utility model relates to the Novel PCB board knot of modular power source technical field, particularly modular power source.
Background technology
In prior art, as shown in Figure 1, metal pins 1 upper end is through the pin bores 21 of pcb board 2, and metal pins 1 lower end is welded together by metal pins cap 11 and the pad 3 being arranged on pcb board 2 lower surface for the pcb board structure of modular power source.There is following defect in this Welding Structure:
1, during welding, need with hand steered firmly metal pins, can ensure that metal pins can not come off, thus once can only weld one, not only production efficiency is low, and the mode of its manual spot welding, also easily occurs rosin joint phenomenon;
2, fixing between metal pins and pcb board, welding of place one's entire reliance upon metal pins cap and pad, when shaking appears in pcb board, easily causes the swing of metal pins and causes coming off of pad;
3, the structure of metal pins wide (except pin cap) up and down, makes it through on pcb board during pin bores, sometimes easily occurs catching phenomenon;
4, during encapsulating, the consistency ensureing height of pin is difficult to.
For this reason, await making improvement to the structure of pcb board.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provide a kind of easy for installation, production efficiency is high, Stability Analysis of Structures, welding are firm, and can ensure the Novel PCB board knot of the modular power source that height of pin is consistent.
The purpose of this utility model is achieved by the following technical programs:
A Novel PCB board structure for modular power source, comprises pcb board and metal pins, described pcb board is provided with the pin bores for installing metal pins and is positioned at pin bores lower end and the welded disc concentric with pin bores; Described metal pins one end is welding ends, this welding ends is provided with conical nose and backstop cap portion, the welding ends of described metal pins is guided by conical nose and welds together with welded disc through after the pin bores on pcb board and welded disc successively, and described backstop cap portion coordinates with the upper surface of pcb board is spacing.
Further, the lower surface of described pcb board is provided with the groove for being installed with welded disc, and the lower surface of described welded disc protrudes from this groove.
Further, the welding ends of described metal pins that section of outer wall between conical nose and backstop cap portion is provided with at least two spacing raised lines be uniformly distributed circumferentially, and the hole wall of the pin bores on described pcb board is provided with the limit sliding chutes with spacing raised line corresponding matching.
Further, described spacing raised line has two or three, and accordingly, described limit sliding chutes also has two or three.
Further, the main part of described metal pins is cylindrical, and described backstop cap portion and welded disc are all in annular.
Further, the other end of described metal pins is the link be connected with device, and this link is provided with screens or screw thread.
Further, described metal pins forms at the basis of copper material upper outside plating layer of metal layer.
Compared with prior art, the utility model tool has the following advantages:
1, the welding ends of metal pins is designed with conical nose, welding ends can be guided to pass through pin bores on pcb board, and there will not be catching phenomenon, thus also facilitate the installation of pin.
2, metal pins is installed to after on pcb board, can ensure self-align, without the need to hand steered, thus can use solder dip process under the effect of backstop cap portion and spacing raised line, increases substantially production efficiency on the one hand, also can avoid rosin joint phenomenon on the other hand.
3, metal pins is except lower end and pad solder, have also been devised the axial limiting to metal pins and circumferential position limiting structure, thus can guarantee that metal pins is weldingly fixed on pcb board solid and reliablely, when pcb board can be avoided to shake metal pins occur swing and then and cause Pad off; Moreover pad itself is arranged in the pre-groove of pcb board bottom surface, also spacing anticreep effect can be played further.
4, under the effect of axial limiting and circumferential position limiting structure, the consistency of each height of pin during encapsulating can be ensured.
