Specific embodiment
It please refers to shown in Fig. 1 to Fig. 7, is that one kind can essence that show the specific structure of the preferred embodiments of the invention
The really TYPE C mould group of insertion pcb board, includes TYPE C mould group 10 and pcb board 20.
Wherein: the end of the TYPE C mould group 10 is equipped with a locating slot 11 for being used for grafting pcb board 20, the TYPE C
The end of multiple conductive terminals extends outward to form two rows of legs 12 in the upper and lower ends of locating slot 11 in mould group 10.In this implementation
In example, the pcb board 20 includes main part 21 and plug division 22, the upper and lower surface of the main part 21 be equipped with it is multiple with it is conductive
The equal pad 23 of number of terminals, pad 23 and the leg 12 of conductive terminal connect one to one；It is coated on the main part 21
Welding resistance oil, the plug division 22 do not apply welding resistance oil and are thinner than one guiding of the formation of main part 21 and carve angle 221.Using do not apply welding resistance oil
What plug division 22 was formed, which carves angle 221, can be convenient plug division 22 and is precisely inserted into locating slot 11, on the one hand can to insert
Socket part 22 is not easy to bump against two rows leg 12 and leg 12 is deformed, and improves reliability when grafting；On the other hand also
Two rows of legs 12 of TYPE C mould group 10 can be made accurately to be overlapped on 23 center of correspondence pad of PCB, can welding
Pin can be climbed up and wrapped well when tin, so that the full smoothness of solder joint.
Specifically, two grooves 201, the plug division are gone out by fine blanking die in the head end two sides of the pcb board 20
22 are formed between two grooves 201.And the two sides of the plug division 22 are equipped with the fillet 222 that can be oriented to grafting.Utilize fine
Mold goes out 22 shape of plug division of PCB, it is ensured that 22 width of plug division positive and negative 0.05mm smaller than the width of locating slot 11；From
And after plug division 22 is inserted into locating slot 11, the whole left and right displacement of pcb board 20 is small；And the fillet 222 being arranged can
So that playing the role of guiding when insertion.It says in more detail, the width of each pad 23 of the pcb board 20 is greater than corresponding
Leg 12 width, the width of each pad 23 is 0.3mm, and the width of each leg is 0.2mm.Every row's leg 12 is
With the first leg 121 and the second leg 122, which is set on six of 10 center of TYPE C mould group the
Two legs 122 are two for being respectively arranged on 10 two sides of TYPE C mould group.The width of pad 23 is set greater than to the width of leg 12
Degree, but can permit the offset 0.05mm in left and right in weld tabs of leg 12 when its connection, but without departing from the region of pad 23.
The manufacturing method of the pcb board 20 includes having the following steps；Prepare pcb board 20 first, pcb board 20 is cut into symbol
Desired size is closed, is punched into groove 201 in the head end two sides of the pcb board 20 using fine blanking die to form pcb board
Main part 21 and plug division 22 are punched into fillet 222 in 22 end of plug division；Then weldering is arranged in the tow sides of main part 21
Disk 23, each pad 23 have certain width；Pad 23 is coated after deploying in 21 tow sides of main part of pcb board 20
Welding resistance oil, the plug division 22 and main part 21 for being not coated with welding resistance oil form one and carve angle 221.It says in more detail, each pad 23
Width must assure that as 0.3mm.The thickness control of the welding resistance oil is in 0.05~0.08mm.
Design focal point of the invention is: by the way that the plug division 22 of pcb board 20 is not applied welding resistance oil, so that plug division 22 is thin
In main part 21, and plug division 22 just forms a guiding and carves angle 221；The guiding, which carves angle 221, can be improved plug division 22 and positioning
Grafting and positioning between slot 11, allow leg 12 to be accurately overlapped on the centre of pad 23；And the guiding carves angle 221
Can also prevent plug division 22 be easy to appear in grafting pcb board 20 it is blocked up and the case where leg 12 is hit deformation so that its
Grafting is more reliable.
The above described is only a preferred embodiment of the present invention, be not intended to limit the scope of the present invention,
Therefore any subtle modifications, equivalent variations and modifications to the above embodiments according to the technical essence of the invention, still
Belong in the range of technical solution of the present invention.
