Abstract
The utility model relates to the encapsulating structure of a kind of pcb board and fuse, comprise pcb board and fuse, fuse is made up of fuse body and pin, fuse is arranged on pcb board, the position hollow out at installation insurance silk place on described pcb board, the hollow out position of the pcb board that fuse body is placed in, the pin of fuse is welded on pcb board.The front and back width at described pcb board hollow out position is than the large 1mm of the width of fuse body; The right and left at pcb board hollow out position is respectively 2mm, 4mm to the distance at two ends, fuse body left and right.The encapsulating structure of pcb board provided by the utility model and fuse, convenient welding, weld time is short, and in welding process, fuse damage less, has effectively ensured encapsulation quality, has saved Material Cost.
Description
Technical field
The utility model relates to the encapsulating structure of a kind of pcb board and fuse.
Background technology
In battery protecting plate, often adopt tack tubulose Thermal Cutoffs, use as battery two segment protects.Tack tubulose Thermal Cutoffs is made up of with the metal pin that is connected two ends fuse body, in the time of PCB and tack tubulose Thermal Cutoffs package design, it on traditional approach, is only the pad as fuse pin with two pads of a determining deviation, by the welding of pin and PCB, thereby fuse body is encapsulated on pcb board.
Tack tubulose Thermal Cutoffs is to responsive to temperature; conventionally protection temperature value is no more than 150 DEG C; in the time that body temperature exceeds protection temperature certain value; fuse does oneself's fusing and cuts off the electricity supply; and Welding iron temperature is up to 370 DEG C, the flatiron temperature of 370 DEG C makes fuse body temperature rise within very short time, in the time that temperature exceeds fuse protection temperature; easily cause fuse damage, the fuse after damage cannot normally use.Traditional fuse encapsulation can only be by widening solder pad space length; rapid welding raises with the body temperature that reduces fuse; and the pin of fuse is parallel with PCB surface; usually need external force that pin is pressed and pad contact weld; not only weld time long, and after External Force Acting, fuse body and the easy deformation of pin link position are impaired; affect fuse performance, also strengthen the internal resistance of baffle.
Utility model content
For addressing the above problem, the utility model provides the encapsulating structure of a kind of pcb board and fuse, and its technical scheme adopting is as follows:
The encapsulating structure of a kind of pcb board and fuse, comprise pcb board and fuse, fuse is made up of fuse body and pin, fuse is arranged on pcb board, the position hollow out at installation insurance silk place on described pcb board, the hollow out position of the pcb board that fuse body is placed in, the pin of fuse is welded on pcb board.
Preferably, the front and back width at described pcb board hollow out position is than the large 1mm of the width of fuse body; The right and left at pcb board hollow out position is respectively 2mm, 4mm to the distance at two ends, fuse body left and right.
By the realization of technique scheme, the encapsulating structure of pcb board provided by the utility model and fuse, convenient welding, weld time is short, and in welding process, fuse damage less, has effectively ensured encapsulation quality, has saved Material Cost.
Brief description of the drawings
Fig. 1 is overall structure figure of the present utility model.
Embodiment
As shown in Figure 1, the encapsulating structure of a kind of pcb board and fuse, comprise pcb board 1 and fuse, fuse is made up of fuse body 21 and pin two 2, position 11 hollow outs at installation insurance silk place on pcb board 1, fuse body is trapped in for 21 times in the position 11 of hollow out, the front and back width at hollow out position 11 is than the large 1mm of the width of fuse body 21, the right and left at hollow out position 11 is respectively 2mm to the distance at fuse body 21 two ends, left and right, 4mm, make the pin two 2 of fuse press close to pcb board, thereby just can be directly welded on pcb board without pressing pin 22, shorten weld time, in welding process, fuse body 21 maximum temperatures reduce, reduce situation about damaging because of excess Temperature, and do not produce deformation after welding, avoid causing the bad situation of Thermal Cutoffs to occur because of extruding break even insurance silk body 21.
Claims (2)
