By adopting technique scheme, plastic cement positioning body and contact pin form connector, weld part inserts the edge PTH hole of PCB and is welded and fixed, contact site is vertical with weld part, contact pin can be realized be connected with turning to of external source device, the hole that contact pin can connect one to one on PCB by pedestal, and be fixed on PCB surface stably, when external terminal is connected with contact site, play the contact performance that wall can strengthen external terminal and contact site, pedestal can improve with the connected mode playing wall the intensity and elasticity that play wall, gap is had between welding and pedestal, pedestal can be avoided to be pressed onto the circuit on edge PTH hole side on PCB, and connector construction is simply compact, take up room on circuit boards little, manufacture simple, production cost is low.

The utility model is set to further: contact pin cross section is square, and described contact pin end is provided with chamfering.

By adopting technique scheme, when in contact pin patchhole, between square and circular hole, also have enough spaces, more solder can be entered, improve the welding performance in contact pin and hole, the chamfer design of contact pin, can hold when using connector in the easy patchhole of contact pin, improving welding efficiency.

The utility model is set to further: the one side playing the relative contact pin of wall is provided with fin, plays wall from fin along the turnover of the another side of relative contact pin, forms folding portion.

By adopting technique scheme, when external terminal is connected with contact site, the design of fin, can improve and play wall to the pressure of external terminal, thus increasing the switching performance of external terminal and contact site, the design of folding portion, then make external terminal easily be connected with contact site.

The utility model is set to further: pedestal is cuboid.

By adopting technique scheme, the pedestal of cuboid is more suitable for being used in single contact pin and fixes, and can be fixed on PCB surface stably, and it is little to take up room.

The utility model is set to further: contact pin quantity is four, and described successive pins center to center spacing is 5mm.

By adopting technique scheme, this is suitable for novel is be used in the connector on PCB that hole center to center spacing is 5.08mm, linear array 4 holes.
